tion pressure. Underinflated tires affect the ability to steer or brake the vehicle. You might lose control over the vehicle.

i With a spare wheel mounted, the system may still indicate the tire inflation pressure of the removed road wheel for some minutes. If this happens, keep in mind that the indicated value where the spare wheel is mounted does not re- flect the actual spare tire inflation pressure.

i When the message Tire pressure is only displayed after driving for a few minutes appears in the multifunction display, the individual inflation pressure values are matched with the tires. The individual values are displayed after a few minutes driving.

Warning!

Warning!

The TPMS does not indicate a warning for wrongly selected inflation pressures. Always adjust tire inflation pressure according to the placard on the driver’s door B-pillar or, if available, the supplemental tire pressure in- formation on the inside of the fuel filler flap.

The TPMS is not able to issue a warning due to a sudden dramatic loss of pressure (e.g. tire blowout caused by a foreign object). In this case bring the vehicle to a halt by care- fully applying the brakes and avoiding abrupt steering maneuvers.

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recom- mended by the vehicle manufacturer on the vehicle placard or the tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or the tire inflation pressure label, you should determine the proper tire infla- tion pressure for those tires). As an added safety feature, your vehicle has been equipped with a tire pressure monitor- ing system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires are significantly underinflated. Accord- ingly, when the low tire pressure telltale illu- minates, you should stop and check your tires as soon as possible. Driving on a signif- icantly underinflated tire causes the tire to overheat and can lead to tire failure.

Operation Tires and wheels

Underinflation also reduces fuel efficiency and tire tread life, and may effect the vehi- cle’s handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driv- er’s responsibility to maintain correct tire pressure, even if underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

i Operating radio transmission equipment (e.g. wireless headsets, two-way radios) in or near the vehicle could cause the TPMS to mal- function.

347

Operation Tires and wheels

Reactivating Advanced TPMS* The TPMS must be reactivated when you have adjusted the tire inflation pressure to a new level (e.g. because of different load or driving conditions). The TPMS is then recalibrated to the current tire inflation pressures.

Warning!

It is the driver’s responsibility to calibrate the TPMS on the recommended cold infla- tion pressure. Underinflated tires affect the ability to steer or brake the vehicle. You might lose control over the vehicle.

왘 Using the tire placard on the driver’s door B-pillar (컄 page 336) or, if avail- able, the supplemental tire pressure information on the inside of the fuel filler flap (컄 page 321), make sure the tire inflation pressure of all four tires is correct.

348

i Reactivate the TPMS after adjusting the tire inflation pressure to the inflation pressure rec- ommended for the vehicle operating condition. Tire pressure should only be adjusted on cold tires. Observe the recommended tire inflation pressure on the placard on the driver’s door B-pillar (컄 page 336). Some vehicles may have supplemental tire pressure information for driv- ing at high speeds (컄 page 342) or for vehicle loads less than the maximum loaded vehicle con- dition (컄 page 342). If such information is pro- vided, it can be found on the inside of the fuel filler flap (컄 page 321). 왘 Press button è or ÿ on the mul-

tifunction steering wheel repeatedly until the standard display menu appears in the multifunction display (컄 page 151).

왘 Press the j or k button repeat- edly until you see the current inflation pressures for each tire appear in the display or the following message ap- pears in the display Tire pressure displayed after driving for a few minutes

i For illustration purposes only. Actual data on tires are specific to each vehicle and may vary from data shown in above illustration.

General: Depending on the design standards used, the tire size molded into the sidewall may have no letter or a letter preceding the tire size designation. No letter preceding the size designation (as illustrated above): Passenger car tire based on European design standards. Letter “P” preceding the size designation: Passenger car tire based on U.S. design standards. Letter “LT” preceding the size designation: Light Truck tire based on U.S. design standards. Letter “T” preceding the size designation: Temporary spare tires which are high pressure compact spares designed for temporary emergency use only.

Tire width The tire width 1 (컄 page 350) indicates the nominal tire width in mm.

Aspect ratio The aspect ratio 2 (컄 page 350) is the dimensional relationship between tire section height and section width and is expressed in percentage. The aspect ratio is arrived at by dividing section height by section width.

Tire code The tire code 3 (컄 page 350) indicates the tire construction type. The “R” stands for radial tire type. Letter “D” means diagonal or bias ply construction; letter “B” means belted-bias ply construction. At the tire manufacturer’s option, any tire with a speed capability above 149 mph (240 km/h) can include a “ZR” in the size designation (for example: 245/40 ZR 18). For additional information, see “Tire speed rating” (컄 page 352).

Operation Tires and wheels

Warning!

Warning!

The tire load rating must always be at least half of the GAWR (컄 page 360) of your vehi- cle. Otherwise, tire failure may be the result which may cause an accident and/or seri- ous injury to you or others.

Always replace rims and tires with the same designation, manufacturer and type as shown on the original part.

Do not overload the tires by exceeding the specified load limit as indicated on the plac- ard located on the driver’s door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure.

For additional information on tire load rating, see “Load identification” (컄 page 354). i Tire load rating 5 (컄 page 350) and Tire speed rating 6 (컄 page 350) are also referred to as “service description”.

Tire speed rating The tire speed rating 6 (컄 page 350) indicates the approved maximum speed for the tire.

Warning!

Even when permitted by law, never operate a vehicle at speeds greater than the maximum speed rating of the tires.

Exceeding the maximum speed for which tires are rated can lead to sudden tire failure, causing loss of vehicle control and possibly resulting in an accident and/or se- rious injury and possible death, for you and for others.

i Tire load rating 5 (컄 page 350) and Tire speed rating 6 (컄 page 350) are also referred to as “service description”.

앫 At the tire manufacturer’s option, any

tire with a speed capability above 149 mph (240 km/h) can include a “ZR” in the size designation (for exam- ple: 245/40 ZR18). To determine the maximum speed capability of the tire, the service description for the tire must be referred to.

The service description is comprised of the tire load rating 5 (컄 page 350) and the tire speed rating 6 (컄 page 350). If your tire includes “ZR” in the size designation and no service description 5 and 6 (컄 page 350) is given, the tire manufacturer must be consulted for the maximum speed ca- pability. If a service description 5 and 6 (컄 page 350) is given, the speed capa- bility is limited by the speed symbol in the service description. Example: 245/40 ZR18 97Y. In this example, “97Y” is the service description. The letter “Y” designates the speed rating and the speed capabil- ity of the tire is limited to 186 mph (300 km/h).

pressure

i For illustration purposes only. Actual data on tires are specific to each vehicle and may vary from data shown in above illustration.

This is the maximum permissible tire inflation pressure for the tire.

Always follow the recommended tire inflation pressure (컄 page 341) for proper tire inflation.

Warning!

Never exceed the max. tire inflation pressure. Follow recommended tire inflation pressures.

Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adverse- ly affect handling and fuel economy, and are more likely to fail from being overheated.

Do not overinflate tires. Overinflated tires can adversely affect handling and ride com- fort, wear unevenly, increase stopping dis- tance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road de- bris, potholes etc.

Uniform Tire Quality Grading Standards (U.S. vehicles)

Tire manufacturers are required to grade tires based on three performance factors: treadwear, traction and temperature resis- tance.

1 Treadwear 2 Traction 3 Temperature resistance

i For illustration purposes only. Actual data on tires are specific to each vehicle and may vary from data shown in above illustration.

357

Operation Tires and wheels

Quality grades can be found, where appli- cable, on the tire sidewall between tread shoulder and maximum section width. For example:

Treadwear Traction Temperature 200

AA

All passenger car tires must conform to federal safety requirements in addition to these grades.

Treadwear The treadwear grade is a comparative rat- ing based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For ex- ample, a tire graded 150 would wear one and one-half (1 1/2) times as well on the government course as a tire graded 100.

358

Temperature The temperature grades are A (the high- est), B, and C, representing the tire’s resis- tance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high tem- perature can cause the material of the tire to degenerate and reduce tire life, and ex- cessive 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 Mo- tor 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.

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 characteristics and climate.

Traction The traction grades, from highest to low- est, are AA, A, B, and C. Those grades rep- resent 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 perfor- mance.

Warning!

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

Warning!

Tire ply material

The temperature grade for this tire is estab- lished for a tire that is properly inflated and not overloaded. Excessive speed, underin- flation, or excessive loading, either sepa- rately or in combination, can cause excessive heat build-up and possible tire failure.

1 Plies in sidewall 2 Plies under tread

i For illustration purposes only. Actual data on tires are specific to each vehicle and may vary from data shown in above illustration.

Rotating tires

Warning!

Rotate front and rear wheels only if the tires are of the same dimension.

If your vehicle is equipped with mixed-size tires (different tire dimensions front vs. rear), tire rotation is not possible.

Tire rotation can be performed on vehicles with tires of the same dimension all around. If your vehicle is equipped with tires of the same dimension all around, tires can be rotated, observing a front-to-rear rotation pattern that will maintain the intended rotation (spinning) direction of the tire (컄 page 336). In some cases, such as when your vehicle is equipped with mixed-size tires (different tire dimension front vs. rear), tire rotation is not possible.

Warning!

Have the tightening torque checked after changing a wheel. Wheels could become loose if not tightened with a torque of 96 lb-ft (130 Nm).

Only use Genuine Mercedes-Benz wheel bolts specified for your vehicle’s rims.

For information on wheel change, see the “Practical hints” section (컄 page 432) and (컄 page 452).

If applicable to your vehicle’s tire configu- ration, tires can be rotated according to the tire manufacturer’s recommended in- tervals in the tire manufacturer’s warranty pamphlet located in your vehicle literature portfolio. If none is available, tires should be rotated every 3000 to 6000 miles (5000 to 10000 km), or sooner if neces- sary, according to the degree of tire wear. The same rotation (spinning) direction must be maintained (컄 page 336). Rotate tires before the characteristic tire wear pattern becomes visible (shoulder wear on front tires and tread center wear on rear tires). Thoroughly clean the mounting face of wheels and brake disks, i.e. the inner side of the wheels/tires, during each rotation. Check for and ensure proper tire inflation pressure.

Operation Winter driving

Before the onset of winter, have your vehicle winterized at an authorized Mercedes-Benz Center. This service includes: 앫 Check of anticorrosion and antifreeze

concentration.

앫 Addition of cleaning concentrate to the water of the windshield and headlamp cleaning system. Add MB Concentrate “S” to a premixed windshield washer solvent/antifreeze which is formulated for temperatures below freezing point (컄 page 500). 앫 Battery test. Battery capacity drops

with decreasing ambient temperature. A well charged battery helps to make sure that the engine can be started even at low ambient temperatures.

앫 Tire change.

Winter tires

Always use winter tires at temperatures below 45°F (7°C) and whenever wintry road conditions prevail. Not all M+S rated tires provide special winter performance. Make sure the tires you use show the mountain/snowflake.marking on the tire sidewall. These tires meet specific snow traction performance requirements of the Rubber Manufacturers Association (RMA) and the Rubber Association of Can- ada (RAC) and have been designed specif- ically for use in snow conditions. Use of winter tires is the only way to achieve the maximum effectiveness of the ABS, ESP® and 4MATIC in winter operation. For safe handling, make sure that all mounted winter tires are of the same make and have the same tread design.

Warning!

Winter tires with a tread depth of less than 1/6 in (4 mm) must be replaced. They are no longer suitable for winter operation.

Always observe the speed rating of the winter tires installed on your vehicle. If the maximum speed for which your tires are rated is below the speed rating of your ve- hicle, you must place a notice to this effect where it will be seen by the driver. Such no- tices are available at your tire dealer or any authorized Mercedes-Benz Center.

Warning!

If you use your spare tire when winter tires are fitted on the other wheels, be aware that the difference in tire characteristics may very well impair turning stability and that overall driving stability may be reduced. Adapt your driving style accordingly.

364

Have the spare tire replaced with a winter tire at the nearest authorized Mercedes-Benz Center.

Block heater* (Canada only)

The engine is equipped with a block heat- er. The electrical cable may be installed at an authorized Mercedes-Benz Center.

Snow chains

! When driving with snow chains, always se- lect the raised level of the level control system Airmatic (컄 page 266). Other settings may result in damage to your vehicle.

! Even on vehicles with all-wheel-drive, use snow chains on rear tires only. Some tire sizes do not leave adequate clearance for snow chains. To help avoid serious damage to your vehicle or tires, make sure that the use of snow chains is permissible as specified in the “Technical data” section of this Operator’s Man- ual, see “Rims and tires” (컄 page 481).

Snow chains should only be driven on snow-covered roads at speeds not to ex- ceed 30 mph (50 km/h). Remove chains as soon as possible when driving on roads without snow. Please observe the following guidelines when using snow chains: 앫 Use of snow chains is not permissible

with all wheel/tire combinations (컄 page 481).

앫 Use snow chains in pairs and on rear wheels only. Follow the manufacturer’s mounting instructions.

! If snow chains are mounted to the front wheels, they may scrape against the body or axle components. The tires or the vehicle could be damaged as a result. 앫 Only use snow chains that are ap-

proved by Mercedes-Benz. Any autho- rized Mercedes-Benz Center will be glad to advise you on this subject.

Operation Winter driving

앫 Use of snow chains may be prohibited depending on location. Always check local and state laws before installing snow chains.

앫 Do not use snow chains on the spare

wheel (컄 page 487).

i When driving with snow chains, you may wish to switch off the ESP® (컄 page 102) before setting the vehicle in motion. This will improve the vehicle’s traction.

i E 63 AMG: Do not switch off the ESP® when driving in snow or with snow chains mounted.

To arrive at the true maintenance service deadline, you will need to subtract these days from the days shown in the maintenance service indicator message or maintenance service indicator dis- play. Do not confuse the maintenance service indica- tor with the engine oil level indicator :.

Resetting the maintenance service indicator

In the event that the maintenance service on your vehicle is not carried out by an au- thorized Mercedes-Benz Center, you can have the maintenance service indicator re- set. The automotive maintenance facility carrying out the maintenance service will find the information for resetting the main- tenance service indicator in the mainte- nance-relevant information for your vehicle. Such information is available from either your authorized Mercedes-Benz Center or directly from Mercedes-Benz.

i If the maintenance service indicator was in- advertently reset, have an authorized Mercedes-Benz Center correct it. Only reset if the proper maintenance service has been performed. Resetting the system without performing the proper service as called for by the maintenance service indicator will result in engine damage and/or other vehicle damage not covered by the Mercedes-Benz Limited Warranty.

왔 Vehicle care Cleaning and care of vehicle

Warning!

Many cleaning products can be hazardous. Some are poisonous, others are flammable. Always follow the instructions on the partic- ular container. Always open your vehicle’s doors or windows when cleaning the inside.

Never use fluids or solvents that are not de- signed for cleaning your vehicle.

Always lock away cleaning products and keep them out of reach of children.

While in operation, even while parked, your vehicle is subjected to varying external in- fluences which, if gone unchecked, can at- tack the paintwork as well as the vehicle underbody and cause lasting damage.

Such damage is caused not only by ex- treme and varying climatic conditions, but also by: 앫 Air pollution 앫 Road salt 앫 Tar 앫 Gravel and stone chipping To avoid paint damage, you should imme- diately remove: 앫 Grease and oil 앫 Fuel 앫 Coolant 앫 Brake fluid 앫 Bird droppings 앫 Insects 앫 Tree resins etc. Frequent washing reduces and/or elimi- nates the aggressiveness and potency of the above adverse influences.

Operation Vehicle care

More frequent washings are necessary to deal with unfavorable conditions: 앫 near the ocean 앫 in industrial areas (smoke, exhaust

emissions)

앫 during winter operation You should check your vehicle from time to time for stone chipping or other damage. Any damage should be repaired as soon as possible to prevent corrosion. In doing so, do not neglect the underbody of the vehicle. A prerequisite for a thor- ough check is a washing of the underbody followed by a thorough inspection. Dam- aged areas need to be re-undercoated. Your vehicle has been treated at the facto- ry with a wax-base rustproofing in the body cavities which will last for the lifetime of the vehicle. Post-production treatment is neither necessary nor recommended by Mercedes-Benz because of the possibility of incompatibility between materials used in the production process and others ap- plied later.

369

Operation Vehicle care

We have selected car-care products and compiled recommendations which are specially matched to our vehicles and which always reflect the latest technology. You can obtain Mercedes-Benz approved car-care products at an authorized Mercedes-Benz Center. Scratches, corrosive deposits, corrosion or damage due to negligent or incorrect care cannot always be removed or repaired with the car-care products recommended here. In such cases it is best to seek aid at an au- thorized Mercedes-Benz Center. The following topics deal with the cleaning and care of your vehicle and give important “how-to” information as well as references to Mercedes-Benz approved car-care prod- ucts.

370

Power washer

! Follow the instructions provided by the pow- er washer manufacturer on maintaining a dis- tance between the vehicle and the nozzle of the power washer. Never use a round nozzle to power-wash tires. The intense jet of water can result in damage to the tire. Always replace a damaged tire. Always keep the jet of water moving across the surface. Do not aim directly at electrical parts, electrical connectors, seals, or other rubber parts.

i Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEYLESS-GO* is in close prox- imity, i.e. within approximately 3 ft (approxi- mately 1 m), the vehicle could be inadvertently locked or unlocked.

Tar stains Quickly remove tar stains before they dry and become more difficult to remove. A tar remover is recommended.

Paintwork, painted body components

! Affixing stickers, magnets, adhesive tape or similar materials to painted body components may damage the paintwork.

Mercedes-Benz approved Paint Care should be applied when water drops on the paint surface do not “bead up”. This should normally be done every 3 to 5 months, de- pending on the climate and washing deter- gent used. Mercedes-Benz approved Paint Cleaner should be applied if the paint surface shows signs of embedded dirt (i.e. loss of gloss). Do not apply any of these products or wax if your vehicle is parked in the sun or if the hood is still hot. 왘 Use the appropriate MB-Touch-Up

Stick for quick and provisional repairs of minor paint damage (i.e. chips from stones, vehicle doors, etc.).

Engine cleaning Prior to cleaning the engine compartment, make sure to protect electrical compo- nents and connectors from contact with water and cleaning agents. Corrosion protection, such as MB Anticor- rosion Wax should be applied to the engine compartment after every engine cleaning. Before applying, all control linkage bush- ings and joints should be lubricated. The poly-V-belt and all pulleys should be pro- tected from any wax.

Vehicle washing In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the vehicle underbody, do not forget to clean the inner sides of the wheels.

i Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEYLESS-GO* is in close prox- imity, i.e. within approximately 3 ft (approxi- mately 1 m), the vehicle could be inadvertently locked or unlocked.

Hand-wash Do not use hot water or wash your vehicle in direct sunlight. 왘 Only use a mild car wash detergent,

such as Mercedes-Benz approved Car Shampoo.

왘 Thoroughly spray the vehicle with a dif-

fused jet of water. Direct only a very weak spray towards the ventilation intake.

왘 Use plenty of water and rinse the sponge and chamois frequently.

왘 Rinse with clean water and thoroughly

dry with a chamois. Do not allow cleaning agents to dry on the finish.

! Do not use scouring agents on these parts. Never apply strong force and only use a soft, non-scratching cloth when cleaning the vehicle. Do not attempt to wipe the surface with a dry cloth or sponge. Otherwise you may scratch or damage the paint.

Operation Vehicle care

Automatic car wash You can have your car washed in an auto- matic car wash from the start. Automatic car washes without brushes are prefera- ble. 왘 To protect the filter system, switch the automatic climate control to air recir- culation mode (컄 page 214) or (컄 page 231).

! Do not clean your vehicle in an automatic touchless car wash which uses caustic spray. Otherwise the caustic spray will damage the paint or ornamental moldings.

If the vehicle is very dirty, prewash it be- fore running it through the automatic car wash.

371

Ornamental moldings For regular cleaning and care of ornamen- tal moldings, use a damp cloth.

Headlamps, tail lamps, side markers, turn signal lenses 왘 Use a mild car wash detergent, such as

! Do not use chrome cleaner on ornamental moldings. Although ornamental moldings may have chrome appearance, they could be made of anodized aluminum that will be damaged when cleaned with chrome cleaner. Instead, use a damp cloth to clean those ornamental moldings. For very dirty ornamental moldings of which you are sure are chrome-plated, use a chrome clean- er. If in doubt whether an ornamental molding is chrome-plated, contact an authorized Mercedes-Benz Center.

Mercedes-Benz approved Car Sham- poo, with plenty of water.

! Only use window cleaning solutions that are suitable for plastic lamp lenses. Window clean- ing solutions which are not suitable may damage the plastic lamp lenses of the headlamps. There- fore, do not use abrasives, solvents or cleaners that contain solvents. Never apply strong force and only use a soft, non-scratching cloth when cleaning the lenses. Do not attempt to wipe dirty lenses with a dry cloth or sponge. Otherwise you may scratch or damage the lens surface.

Operation Vehicle care

! Make sure that the windshield wiper switch is set to M (컄 page 58). Otherwise, e.g. the rain sensor could activate and cause the wipers to move unintentionally. This may lead to vehicle damage. Due to the width of the vehicle, fold in exterior rear view mirrors prior to running the vehicle through an automatic car wash to prevent dam- age to the mirrors.

i After running the vehicle through an auto- matic car wash, wipe any wax off of the wind- shield (컄 page 374) and the wiper blade inserts (컄 page 374). This will prevent smears and re- duce wiping noise which can be caused by resid- ual wax on the windshield. When leaving the car wash, make sure that the mirrors are folded out. Otherwise they may vibrate.

Operation Vehicle care

Cleaning the windows and the wiper blades

Warning!

! The windshield wipers must be in a vertical position before folding them away from the wind- shield. They could otherwise damage the hood. Never open the hood when the wiper arms are folded forward. 왘 Make sure the hood is fully closed. 왘 Switch on the ignition (컄 page 38). 왘 Turn combination switch to wiper

setting u (컄 page 58).

왘 With wiper arms in vertical position,

switch off the ignition (컄 page 63).

For safety reasons, switch off wipers and re- move SmartKey from starter switch (vehi- cles with KEYLESS-GO*: Make sure the vehicle’s on-board electronics have status 0) before cleaning the windshield and/or the wiper blades. Otherwise, the wiper motor could suddenly turn on and cause injury.

! Do not pull on the wiper blade inserts. They could tear. 왘 Fold the wiper arms forward until they

snap into place.

왘 Clean the wiper blade inserts with a

clean cloth and detergent solution.

왘 Use a soft, clean cloth and a mild win-

dow cleaning solution on all outside and inside glass surfaces. An automotive glass cleaner is recom- mended.

374

Cleaning the panorama roof with power tilt/sliding panel The rear part of the tilt/sliding panel has a protective layer on the inside. 왘 Use a soft, clean cloth and a mild win-

dow cleaning solution. An automotive glass cleaner is recom- mended.

Light alloy wheels If possible, clean wheels once a week. 왘 Use Mercedes-Benz approved Wheel Care, a soft bristle brush and a strong spray of water for cleaning the light al- loy wheels.

! Only use acid-free cleaning materials. Acid may cause corrosion or damage the clear coat.

! Do not use a dry cloth, abrasives, solvents or cleaners containing solvents. Do not touch the protective layer with hard objects such as an ice scraper or ring. Never apply strong force and only use a soft, non-scratching cloth when clean- ing the rear part of the tilt/sliding panel. Otherwise you may scratch or damage the pro- tective layer.

! The vehicle should not be parked for an ex- tended period of time immediately after it has been cleaned, especially not after the wheel rims have been cleaned with wheel rim cleaner. Wheel rim cleaners can lead to increased corro- sion of the brake disks and brake pads. Non-ap- proved wheel cleaners may also damage the wheel paint if the car is not driven after cleaning. Therefore, the vehicle’s brake system should al- ways be warmed-up before it is parked after cleaning. To do so, please drive your vehicle for several minutes to allow the brakes to dry. When applying Mercedes-Benz approved Tire Care and Mercedes-Benz approved Wheel Care products, take care not to spray them on the brake disks.

Operation Vehicle care

Plastic and rubber parts 왘 Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution.

왘 Wipe with a cloth moistened in a luke-

warm solution. The surface may temporarily change color. If this is the case, wait for it to dry.

Warning!

Do not use cleaners or cockpit care sprays containing solvents to clean the cockpit or the steering wheel. Cleaners containing sol- vents will make the surface porous and vehi- cle occupants could suffer serious injuries from plastic parts coming loose in the event of air bag deployment.
