WARNING

MAX +80°

(cid:127) Prolonged and repeated exposure of the skin to engine oil can cause seri- ous skin disorders.

(cid:127) Avoid prolonged skin contact when-

ever possible. Wash the affected area thoroughly with soap and water after any contact.

(cid:127) Keep oil out of reach of children.

(cid:127) Do not touch the turbocharger or

manifold. These get very hot when the engine has been running.

(cid:127) Do not spill oil on hot parts of the

engine as this could cause a fire. Used engine oil is particularly flammable.

(cid:127) Protect the environment. Do not dis- pose of oil in the ground or down a drain. Dispose of all used oil and oil fil- ters at an appropriate disposal facility.

+80° MIN

Oil dipstick, automatic transmission

Transmission fluid Manual transmission Check and top up the fluid in accordance with the service program. If original fluid cannot be obtained for top- ping up, Dextron III (synthetic fluid) auto- matic transmission fluid can be used. If so, the car should be taken to an authorized Saab dealer as soon as possible to have the reason for low fluid level corrected and orig- inal fluid installed. Automatic transmission Check the fluid level as follows: 1 Park the car on level ground and apply the parking brake. The automatic trans- mission fluid must be at normal running temperature, approximately 175°F

(cid:127) 192

Car care

(80°C). This can be achieved by driving the car for about 30 min on the open road.

2 With the engine idling, move the selector

lever to D and wait for at least 15 seconds. Next, move the selector lever to R and wait for 15 seconds again. Finally, move the selector lever to P. Let the engine idle.

3 Wipe the dipstick clean with a lint-free

cloth and put it back.

4 With the fluid at normal temperature, the

level should be between the MAX and MIN marks on the dipstick. Top up, as necessary, with Texaco Texamatic Dex- tron III automatic-transmission fluid, adding it through the dipstick pipe. The distance between the MIN and MAX marks on the dipstick corresponds to a volume of approximately 0.4 qts (0.4 litre).

NOTE

If there is a burnt smell or the fluid is black, change the fluid as soon as possible.

If the outside temperature is below 50°F (10°C), the fluid will not reach the specified temperature of 175°F (80°C). In this case, the correct fluid level may be 0.8 in (20 mm) below the MAX mark.

Coolant

WARNING

(cid:127) Proceed with caution if the radiator is

boiling when you open the hood. Never remove the expansion-tank filler cap when the radiator is boiling. Loosen the cap carefully, and let the engine cool before removing the cap.

(cid:127) The cooling system is pressurized – hot coolant and vapor can escape when the filler cap is released.

(cid:127) Exercise care when adding coolant.

Coolant on hot surfaces constitutes a fire risk.

The expansion tank is transparent, to facili- tate checking. The level must be a little under the mark ”KALT – COLD” on the tank when the engine is cold. If the SID message "FILL COOLANT FLUID" is displayed, the level in the expansion tank should be checked. Top up as necessary with equal parts of clean water and coolant. Use only coolant approved by Saab. If the expansion tank is empty when coolant is added, run the engine to normal temper- ature and top up again, as necessary.

Coolant expansion tank

Coolant The cooling system is filled at the factory with coolant containing a 50% concentra- tion of a combined antifreeze and corrosion inhibitor. A weaker mixture will result in reduced anticorrosion protection. For pro- tection against freezing in very cold weather, a stronger concentration will be needed. A 60% concentration of antifreeze will pro- vide protection at temperatures down to -58 F (-50°C).

Car care

193

Air filter

WARNING

Only use an air filter recommended by Saab Automobile AB.

The coolant does not normally have to be changed during the service life of the car. This type of coolant has a reddish colour and should not be mixed with other types of coolant. Saab Original coolant should be used all year round. Only use coolant approved by Saab.

NOTE

Always mix the antifreeze with the appropriate volume of water before adding it to the cooling system. If pure antifreeze is added, the engine could still freeze and be damaged. This is because the antifreeze will not mix properly with the coolant before the thermostat has opened to allow full circulation.

Brake pad wear indicators The outboard brake pads on the front wheels incorporate pad-wear indicators. When the lining is down to 0.11 in (3 mm), the pad will produce a screeching, squeal- ing or scraping noise when the brakes are applied. New pads should be installed with- out delay. Brake pads should only be changed by an authorized Saab dealer. To ensure optimum brake performance, use only Saab original brake pads.

Car care

194
Brake- clutch fluid and brake pads

WARNING

Brake fluid deteriorates as it becomes old. Because it is hygroscopic, it absorbs water from the air and, in time, could allow vapor to form in the brake system, thus reducing its performance. It is therefore important that brake fluid be changed reg- ularly, as specified in the service pro- gram.

Checking the fluid level The combined brake and clutch-fluid reser- voir is transparent to facilitate checking of the fluid level. The level should be between the MAX and MIN marks. Top up, as necessary, with DOT 4 fluid. Do not use DOT 5 brake fluid. Use only new brake fluid from a sealed con- tainer. Check that there are no leaks in the brake system. Changing of the brake fluid should be carried out by an authorized Saab dealer.

The vehicle´s regular braking system is adjusted automatically, but the parking brake has to be adjusted manually. This work, involving adjustment of the parking brake cables and brake pads, must only be carried out by an authorized Saab dealer. It is not possible to detect, through abnormal pedal or parking brake-lever travel, whether brake pads are worn and need replacing. It is therefore essential that brake pads be checked regularly, as specified in the ser- vice program..

NOTE

Avoid spilling brake fluid onto paintwork, since it can cause the paint to bubble and lift. If any brake fluid is spilled, the area should be flushed with large quantities of water as quickly as possible.

Power steering fluid reservoir

Car care

195

Battery

WARNING

(cid:127) Work on the battery may entail an

explosion hazard, since the battery gives off hydrogen which forms an explosive mixture with the oxygen in the air. For this reason, always avoid sparks or open flames when working near the battery.

(cid:127) The battery contains corrosive sulphu- ric acid. Always wear a face mask or goggles when working on the battery.

(cid:127) If battery acid gets into the eyes or

splashes the skin or clothing, wash the affected area liberally with water. If acid gets into the eyes or a large quantity makes contact with the skin, seek medical help.

Power steering

WARNING

Do not fill the power steering fluid to above the MAX mark. Too much fluid can result in leakage. Power steering fluid on hot engine com- ponents constitutes a fire risk.

Check the level of the power-steering fluid in the reservoir regularly, in accordance with the service program. The wheels should point forward during the check. Clean around the cap before it is unscrewed. Unscrew the cap and wipe the dipstick. To check the fluid level, first screw the cap on fully again and then remove. The level should be between the MAX and MIN marks on the dipstick when the oil temperature is about 68°F (+20°C). If the oil is colder the oil level can be lower, and in higher tempera- tures the level can be higher, both of which are acceptable. Top up with power-steering fluid CHF 11S (part number 8996860).

196

Car care

A car with standard equipment and a fully charged battery can be left for up to 40 days and still have a sufficient charge for starting. If extra equipment is fitted, such as a mobile telephone, the time may be reduced to about 15 days. Always connect the positive (red) cable to the positive (+) terminal of the battery and the negative (blue) cable to its negative (-) terminal. Always disconnect both battery leads when boost charging the battery.

NOTE

• Don’t connect the battery terminals

+ and – the wrong way around.

(cid:127) Serious damage can occur to the car’s electrical system if a battery or alterna- tor lead is disconnected while the engine is running.

Correct fluid level in the battery

Taking out the battery

The liquid level in the car battery must be checked at regular intervals.

NOTE

NOTE

Never use tap water to top up the battery. Use distilled or boiled water.

Tap water contains salts and minerals that accelerate the corrosion of the battery elec- trodes, which can shorten the life of the bat- tery. The charge level should be checked with a battery-acid tester. The specific gravity of the acid in a fully charged battery should be 1.28. A specific gravity of 1.18 roughly indi- cates a 50% charge.

A discharged battery can freeze and frac- ture. Batteries should therefore always be stored away from frost.

If frequent short journeys are made in cold weather, the battery may need to be given a booster charge. This can be done either using a battery charger or by taking the car for a long drive.

Drive belt

WARNING

Car care

197

(cid:127) Keep hands and clothing clear of drive

belts when engine is running. (cid:127) Always stop the engine before

inspecting drive belts.

(cid:127) The fan can start even when the

engine is switched off.

NOTE

Drive belt

Serious damage can occur to the car’s electrical system if an alternator lead is disconnected while the engine is running.

The alternator is situated on the right-hand side of the engine. It is driven via a poly-V belt from the crankshaft pulley. The poly-V-belt also drives the water pump, the A/C compressor and the steering servo pump. The belt tension is critical, and is adjusted by an automatic belt tensioner. See also page 61, "Warning charging".

Car care

198
Wipers and washers Wiper blades Check and clean all wiper blades regularly. We recommend Saab washer fluid for cleaning. If poor wiper performance is experienced, clean the windshield with Saab washer fluid. This is particularly important if the car has been through an automatic car wash, as this sometimes leave a wax coating on the wind- shield. If wiper performance is still unsatisfactory, fit new blades.

WARNING

Take care not to spill washer fluid concen- trate onto hot surfaces as this constitutes a fire hazard.

Windshield and rear window 1 Push the catch in (1). 2 Pull the complete wiper blade down-

wards so that it comes away from the wiper arm. Slide the entire blade out from the arm.

Headlight wipers 1 Lift the wiper arm off the headlight. 2 Detach the wiper blade by pulling it

laterally from the wiper arm.

3 Fit the new blade by sliding it into the

retainer on the wiper arm and pressing it firmly home.

Car care

199

Washer jets The washer jets, which are adjustable, can be cleaned with a pin if necessary. The jet for rear-window washing is located in the right-hand part of the high-mounted brake light.

Washer-fluid reservoir

Washer The reservoir holds 5 quarts (4.7 litres). When the SID message "WASHER FLUID LEVEL LOW" appears there is about 1.5 quarts (1.4 litres) left. Fill with quality washer fluid, available from your Saab dealer and follow the instructions on the package to reduce the risk of freez- ing. Note: If the reservoir is run dry and the car has a rear-window wiper, then after refilling you cannot wash the rear window until you have first washed the windscreen.

Tool for changing fuses

WARNING

To avoid the risk of short-circuiting and/or fire breaking out in the electrical system, the following advice should be heeded: (cid:127) Always consult an authorized Saab

dealer before modifying or adding any electrical equipment. Failure to do so can result in the electrical system being damaged.

(cid:127) Never replace a fuse with one having a

higher/lower rating than specified (see page 208). The color of the fuse indicates its amperage.

(cid:127) If the same fuse blows repeatedly,

have the electrical system checked by an authorized Saab dealer.

(cid:127) If a MAXI fuse blows, it means that

there is a major fault in the electrical system. Have the car checked without delay by an authorized Saab dealer.

Car care

206
Fuses The fuses are housed in two fuse panels: one at the end of the instrument panel on the driver’s side, and one under the hood. To check if a fuse has blown, first remove it from the panel (see below). If the filament is broken, the fuse has blown. A special tool for removing fuses is provided at the bottom of the fuse panel on the fascia. Simply push the tool onto the fuse, squeeze and remove the fuse.

Car care

207

The DICE and TWICE control modules are linked to a data bus, which is basically an information carrier that allows information to be exchanged between all the control mod- ules and components connected to the bus. If a fault occurs in any of these components, diagnostic faults codes are set in the rele- vant control module, which enhances fault diagnosis at the Saab dealer. The scan tool connector for fault diagnosis is located under the instrument panel on the driver’s side.

MAXI fuse for soft-top system (Convertible)

MAXI fuses The MAXI fuses are housed in the fuse box under the hood. These fuses can be checked in the same way as the other fuses. The MAXI fuses are designed to protect the car’s electrical system from being dam- aged. Each MAXI fuse protects a number of electrical circuits and functions and there- fore has a higher rating (amperage) than the standard fuses. No spare MAXI fuses are supplied with the car.

NOTE

If a MAXI fuse blows, it means that there is a major fault in the electrical system. Have the car checked without delay by an authorized Saab dealer.

Wheels Alternative wheels and tires If you wish to fit other tires or wheels than those supplied with the car, consult your Saab dealer first as to the possibilities avail- able. Wheels/tires combinations that are not approved by Saab can negatively affect the car´s directional stability, steering and brak- ing in both wet and dry conditions. Do not assume that a wheel/tire combina- tion will function properly just because it will bolt on. To ensure that the speedometer is as accu- rate as possible it should be reprogrammed if wheels of a different dimension are fitted. Contact an authorized Saab dealer.

NOTE

For wide wheels and/or low-profile tires, bear in mind the following: (cid:127) Tires and wheels can be damaged in

potholes etc.

(cid:127) Springs, shock absorbers and wheel

bearings and body mountings can be overloaded.

(cid:127) The wheels can come into contact with

chassis and body components.

(cid:127) The speed and load limits for the tires must not be exceeded; see page 212.

(cid:127) Wheels larger than 17” must not be fitted on the Saab 9-3. For Viggen models the wheel should not be larger than 17”. The maximum permissible offset for the 9-3 is 49 mm and for the Viggen 42 mm.

(cid:127) Wheels smaller than 16” must not be

fitted on Viggen models. Fitting a smaller size wheel on a Viggen is not possible due to the size of the brake discs.

The wheels and tires have been carefully matched to the characteristics of the car and play a key role in its outstanding roadhold- ing and handling.

Car care

211

Tire pressure

NOTE

Check the tire pressures at least once per month. Underinflation is the main cause of: (cid:127) Tires wearing out prematurely. (cid:127) Damage to the sidewalls. (cid:127) Damage to the wheels.

Tires need to be inflated to suit the load car- ried and the maximum speed the car will be driven (see the recommended tire pres- sures on the back cover). Tire pressure label, see page 243. Note that all values apply to cold tires. For tires with an aspect ratio less than /60, increase the tire pressure by 3 psi (20 kPa) for rough roads with potholes to minimize the risk of rim damage. Never reduce the pressure of a hot tire. If the tires are hot when you check them, only increase the pressure, if necessary. Soft tires will cause faster wear than over-pressurized tires. They also increase fuel consumption. If a valve is leaking, simply unscrew it and fit a new one. Important! Remember to adjust the tire pressures if you change the load in the car or intend to cruise at a substantially higher or lower speed than normal.

212

Car care

Rotating the tires

WARNING

When fitting just one new pair of tires, these should be fitted to the rear wheels, as these are more critical to the direc- tional stability of the car (e.g. on braking or in a skid). The existing rear tires should therefore be moved to the front. Always move left rear to left front and right rear to right front, so that the direction of rotation remains the same.

Because of front wheel drive, the front tires tend to wear faster than the rear ones. New tires should always be fitted in pairs, so that tires on the same axle have the same amount of tread. The wheels should be marked, L (left) and R (right), when changing between summer and winter (snow) tires. This ensures that the direction of rotation of the wheels is the same when they are refitted. Fit the tires in best condition to the rear wheels. Store wheels lying flat or hanging – never standing upright.

Tire markings An example of the meaning of the different markings in a tire size is given below for a tire size of 205/55 R16 91V:

205 Tire section width, mm 55 Aspect ratio, i.e. the section height

is 60 % of the section width

R Radial ply 16 Wheel rim diameter 16 in. at bead

H Tire approved for speeds up to

130 mph (210 km/h)

V Tire approved for speeds up to

150 mph (240 km/h)

W Tire approved for speeds up to

167 mph (270 km/h)

Y Tire approved for speeds up to

186 mph (300 km/h)

Winter tires Winter (snow) tires are recommended for winter climates where the majority of your driving will be done on snow and ice. Winter tires should be fitted to all four wheels to maintain a proper balance. Your Saab dealer can advise you of to the correct size tire for your car (if different from the original size) and also supply Saab approved winter tires pre-mounted on steel or alloy rims. Tire quality grading (cars sold in U.S.) New tires must be graded and labeled in accordance with new Federal regulations. Standard tests are conducted to measure performance in the areas of traction and temperature resistance. Refer to the tire sidewall for the specific quality grades of the tires provided on your new Saab. Compact spare tires are exempt. DOT QUALITY GRADES (cid:127) Treadwear. (cid:127) Traction AA, A, B, C. (cid:127) Temperature A, B, C. All passenger car tires must conform to Fed- eral safety requirements in addition to these grades.

Uniform Tire Quality Grading (US) Quality grades can be found where applica- ble on the tire sidewall between tread shoul- der and maximum section width. For exam- ple: Treadwear 200 Traction AA Temperature A Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one half (1 1/2) times as well on the gov- ernment course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road character- istics and climate.

Traction The traction grades, from highest to lowest, are AA, A, B and C. These grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.

WARNING

The traction grade assigned to a tire is based on straight-ahead braking, traction test and does not include acceleration, cornering, hydroplaning or peak traction characteristics.

Car care

213

Temperature The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dis- sipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life. Excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

WARNING

The temperature grade for a tire is estab- lished for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire fail- ure.

Date code Tires should be regarded as perishable goods. As the tires age, the rubber becomes progressively harder, and the roadholding ability of the tires diminishes. This is partic- ularly true on winter tires. Tires now have a date-code marking for the year of manufacture. The first two digits denote the week number and the last two digits the year. The ”<” symbol points to the year. Accordingly, a date code of 0200 signifies that the tire was manufactured in week 02, 2000.

Wear indicators The tires incorporate wear indicators in the form of smooth, treadless strips across the width, which become visible when only 2/32" (1.6 mm) of tread remains. As soon as the indicators become visible, new tires should be fitted without delay. Make sure you are familiar with the legal limit for minimum tread depth in your country and also any regulations gov- erning the use of winter (snow) tires.

Spare wheel (under the carpet in the trunk)

Compact spare wheel The compact spare is light and easy to handle when changing the wheel. Its use is only permitted when a standard tire has sus- tained a puncture. The maximum life of the tire is only 2000 miles (3,500 km). Do not exceed 50 mph (80 km/h) with the compact spare fitted. The compact spare should be inflated to 60 psi (420 kPa). Carry the punctured tire in the spare-wheel well under the trunk floor. Have the standard tire repaired and refitted as soon as possible Driving considerations with compact spare wheel/tire fitted, see page 184. The spare wheel, the tools and the jack with its crank are carried under a panel in the trunk.

(cid:127) Stow the jack in the place provided for

it under the panel in the floor of the trunk. Secure it properly to avoid injury to passengers in the event of a crash.

(cid:127) Do not use the jack for any purpose

other than for jacking up the car.

(cid:127) If light-alloy wheels have been fitted to the car for several years and a change is made to steel wheels, the threads for the wheel bolts in the brake discs should be cleaned before the thinner steel wheels are fitted. The innermost threads in the holes may be clogged with sand, salt and rust so that the cor- rect tightening torque cannot be achieved.

Changing a wheel

WARNING

(cid:127) The car jack is designed solely for use

in changing a wheel or fitting snow chains. It must not be used to support the car during repair work or servicing.

(cid:127) Never crawl under a car that is

supported only by a jack.

(cid:127) Special care must be taken if the car is

on a slope – use wheel chocks!

(cid:127) Position chocks, one ahead and one behind, the wheel that is diagonally opposite to the one to be changed.

(cid:127) Switch on the hazard warning lights if

the car is on a road.

(cid:127) Apply the parking brake and leave the car in gear (1st or reverse). Automatic transmission: move selector to the P position.

(cid:127) Ensure that everybody is out of the car

before jacking it up.

(cid:127) Never start the engine while the car is

jacked up.

(cid:127) The jack must stand on a firm, level

surface.

When changing a wheel, take the tool kit out first, then the spare wheel.

NOTE

To avoid damaging an alloy wheel with a flat tire, this can be placed outside up in the spare-wheel well but only while driv- ing to the closest workshop. A general rule is that all heavy loads must be well secured in the luggage compart- ment, see page 142.

Car care

Position for jack

When it is time to raise the car, apply the jack to one of the four jacking points (front or rear) located beneath the sills. If a floor jack is used it can be applied to the standard jacking points used by the dealer or centrally under the front of the engine subframe. If the car is equipped with a trailer hitch, the jack can also be placed under the hitch.

NOTE

(cid:127) Do not position the jack under the rear

axle or under the rear floor.

(cid:127) Only use the points specified on

page 217.

Positioning the jack

1 Put the car in 1st gear (automatic trans- mission: move selector to the P position) and apply the parking brake. Saab 9-3 Viggen: The front and rear jacking points are located behind covers that must be removed. See page 217.

2 Wind the jack up to a suitable height

before placing it under the recess in the sill.

3 Make sure that the jack fully engages

the recess in the sill and that the base of the jack is steady and flat on the ground.

4 Turn the jack handle clockwise until it

just begins to lift the car.

5 Remove the wheel cover (where appli- cable). Loosen the wheel bolts by half a turn.

6 Turn the jack handle to raise the wheel clear of the ground. Remove the wheel bolts and lift off the wheel.

7 Clean the contact surfaces between the

rim and hub.

8 Fit the wheel and screw in the bolts in the

sequence shown (opposite pairs). Tighten the studs enough for the studs and wheel to be seated correctly. See page 218 for sequence.

9 Lower the car and tighten the wheel

bolts to the correct torque in the sequence shown (opposite pairs). Tightening torque: Light-alloy wheels: 80 ft.lbs (110 Nm). Steel wheels: 80 ft.lbs (110 Nm)

miles. Tightening torque: Light-alloy wheels: 80 ft.lbs (110 Nm) Steel wheels: 80 ft.lbs (110 Nm)

We advise against using wheels with open wheel covers in winter, as the brake compo- nents are then more exposed both to slush and to road salt and grit.

NOTE

Do not overtighten the bolts using an impact wrench: not only can this damage the wheels but it can also make it impos- sible to undo the bolts using the wheel wrench in the car’s toolkit.

Flat spotting All tires get hot, especially on long journeys or when the car is driven hard. After the car has been parked with hot tires and the tires have cooled down, a flat spot can form in the tire, where it is in contact with the ground. The same can occur if the car has not been moved for a long time. Flat spots can cause vibration that can be felt through the steering wheel, similar to that experienced when the wheels need bal- ancing. Flat spots of this type disappear once the tires get hot again, usually after 10–15 miles (20–25 km) of driving at cruis- ing speed.

Safety belts

WARNING

Safety belts and belt pretensioners that were in use in a serious crash must be replaced even if they are not visibly damaged. No attempt must be made to repair, or modify the function of, safety belts.

A check should be made periodically to ensure that the safety belts are working properly. (cid:127) Hold the diagonal strap and pull it sharply. The safety belt should lock and it should not be possible to withdraw it further.

A sharp tug on the belt should cause the inertia reel to lock. Check the floor anchor- age points for corrosion damage. If a belt is worn or has any fraying edges, it should be replaced. Safety belts must not come into contact with substances such as polishes, oil or chemi- cals. If the belts get dirty, wash them with warm water and a detergent or have them replaced.

Textile carpeting Vacuum clean the carpeting regularly. Car- pets can also be cleaned using a brush, or carpet shampoo applied with a sponge. Do not use vacuum cleaners outdoors unless they are properly grounded.

Upholstery and trim To remove fluff or hairs from the seat uphol- stery or headlining, use a moist, lint-free cloth or a special lint remover (brush or roller). Remove any dirty marks using a cloth moistened with lukewarm soapy water. When using a stain remover, always work from the outside towards the center to avoid leaving a ring. If a soiled ring or spot should remain, it can usually be removed using lukewarm soapy water or water alone. Wet patches left by spilled soft drinks or thin oil must be wiped off immediately using an absorbent material, such as paper toweling, and treated with stain remover. Isopropyl alcohol is recommended for removing grease or oil stains, and a semi-stiff brush may also be used.

Cleaning and caring for leather upholstery The principal reason for treating leather upholstery is to maintain its elegant appear- ance and to provide it with a protective film. Discoloration caused by dust and wear mainly affects the lighter shades, although this is not detrimental to the leather – indeed, the patina resulting from use is often considered desirable in leather. But if the leather is allowed to become too grubby, it can start to look shabby. The leather upholstery should be cleaned and reconditioned twice a year in conjunc- tion with spring and autumn inspections. In very warm, dry climates the leather may need more regular reconditioning. Recom- mended conditioner - Saab Leather Care Lotion. Do not use unknown harsh polishing agents, cleaning agents, sprays, coarse soap or hot water. The leather will be clean and attractive for many years.

Car care Engine bay Clean the engine compartment using an engine detergent and rinse with hot water. Cover the headlights. Do not use a high-pressure washer Avoid spraying the hood liner, as this can become heavy and hang down and touch the engine when the hood is closed. Do not use gasoline as a cleaning agent or solvent when carrying out repairs or mainte- nance. Saab recommends the use of envi- ronmentally safe degreasing agents.

The underside of the car also needs wash- ing regularly, and this should be done very thoroughly at the end of winter. Clean the underside of the car by hand if the car is usu- ally washed in an automatic car wash with- out special facilities for underbody cleaning. Never wash or leave the car to dry in the sun, but wipe it dry with a chamois leather immediately after washing to avoid smears and streaks. Clean the window glass inside and out using a high quality window cleaner. This is partic- ularly important when the car is new, as upholstery and trim have a tendency to sweat a little at first. Keep the glass well cleaned, as this helps to prevent misting.

Washing The bodywork must be washed frequently. When the car is new, the body should be washed by hand using plain cold water and a clean, soft brush, or in a brushless car- wash that uses mild detergent. Automatic carwashes with brushes should be avoided when the car is new. Do not use automatic car washes for the first five or six months, before the paintwork has hardened prop- erly. Thereafter, use a high quality car wash soap added to lukewarm water. Do not use a pressure washer at close range on stone chip damage, scratches or other damage to the paintwork. The paint can otherwise start to flake. Remove any bird droppings without delay, as these can discolor the paintwork and prove difficult to polish out. Use a soft cloth moistened with methyl alco- hol to remove splashes of tar or asphalt. Do not use strong cleaners, as these can dry out the paintwork.

NOTE

Avoid using any alcohol-based cleaners on the front and rear light clusters, as these can cause cracking of the lenses.

NOTE

(cid:127) Try your brakes on leaving a car wash. Wet brake discs reduce the braking effect.

(cid:127) Turn off the radio before entering an

automatic car wash so the power antenna mast does not get damaged.

(cid:127) Clean the rod of the electrically pow-

ered antenna about once a month with a clean, dry rag. IMPORTANT! Use no oil, nor any sili- cone-based cleaning product.

(cid:127) Fixed antennas must be removed

when going through an automatic car wash.

(cid:127) Saab 9-3 Viggen: If you wash the car

in an automatic car wash, you must first remove the roof-mounted antenna, otherwise it will be damaged.

Waxing and polishing Do not wax a new car during the first three or four months. In fact, there is no need to polish the car before the paintwork has started to go dull through oxidation. Other than in exceptional cases, do not use abra- sive polishes containing a cutting agent on a new car. Always wash the car thoroughly before waxing or polishing.

Touching up the paint Damaged paintwork should be treated as soon as it is discovered: the longer it is left, the greater the risk of corrosion. The anti-perforation warranty does not cover corrosion resulting from untreated defects. Paintwork damage sustained in a crash is usually extensive and can only be properly restored by professionals. However, you can repair small scratches and stone-chip damage yourself. The nec- essary tools and materials, such as primer, touch-up paint and brushes, are available from your Saab dealer. In the case of minor flaws in the paintwork, where the metal has not been exposed and an undamaged layer of paint remains, touch-up paint can usually be applied directly, after any dirt has been scraped away using a pointed knife. If corrosion has already set in, e.g. as a result of stone-chip damage, use a pointed knife to scrape off all surface rust. If possi- ble, the damaged area should be taken back to the bare metal. The metal should then be primed with two thin coats of primer applied by brush. After the primer has dried, apply several thin layers of topcoat enamel until the surface of the repaired area is flush with the surround- ing paintwork. Stir both primer and touch-up enamel thor- oughly before use and allow each coat to dry before applying the next.
