to painted surfaces. You could otherwise damage the paintwork.

If water no longer forms "beads" on the paint surface, use the paint care products recommended and approved by Mercedes- Benz. This is the case approximately every three to five months, depending on the climate conditions and the care product used. If the dirt has penetrated the paint surface or if the paintwork has become dull, then the paintwork should be cleaned. For cleaning, please use the paint cleaner recommend and approved by Mercedes Benz. Do not use these care products in the sun or on the hood while the hood is hot. X Use a suitable touch-up stick, e.g. MB

Touch-Up Stick, to repair slight damage to the paintwork quickly and provisionally.

Matte finish care If your vehicle has a clear matte finish, observe the following instructions in order to avoid damage to the paintwork due to incorrect care. These notes also apply to light alloy wheels with a clear matte finish. ! Never polish the vehicle or the light alloy

wheels. Polishing causes the finish to shine.

! The following may cause the paint to

become shiny and thus reduce the matte effect: RVigorous rubbing with unsuitable

materials.

RFrequent use of car washes. RWashing the vehicle in direct sunlight.

! Never use paint cleaner, buffing or

polishing products, or gloss preserver, e.g. wax. These products are only suitable for high-gloss surfaces. Their use on vehicles with matte finish leads to considerable surface damage (shiny, spotted areas).

i When you are driving with the emergency

spare wheel mounted, the tire pressure monitoring system cannot function reliably. Only restart the tire pressure monitoring system when the defective wheel has been replaced with a new wheel. All wheels mounted must be equipped with functioning sensors. The defective wheel should no longer be in the vehicle.

MOExtended tires (tires with run-flat properties) With MOExtended tires (tires with run flat characteristics), you can continue to drive your vehicle even if there is a total loss of pressure in one or more tires.

442 Battery

MOExtended tires may only be used in conjunction with the activated tire pressure loss warning system or with the activated tire pressure monitoring system. The driving distance in partially laden condition is approximately 50 miles (80 km), and approximately 18 miles (30 km) when fully loaded. In addition to the vehicle load, the driving distance possible depends upon: Rspeed Rroad condition Routside temperature The driving distance possible in run-flat mode may be reduced by extreme driving conditions/maneuvers, or it can be increased through a moderate style of driving. The maximum permissible distance which can be driven in run-flat mode is counted from the moment the tire pressure loss warning appears in the multifunction display. Do not exceed a vehicle speed of 50 mph (80 km/h). G WARNING When driving in emergency mode, the driving characteristics deteriorate, e.g. when cornering, accelerating quickly and when braking. There is a risk of an accident. Do not exceed the stated maximum speed. Avoid abrupt steering and driving maneuvers, and driving over obstacles (curbs, potholes, off-road). This applies in particular to a laden vehicle. Stop driving in emergency mode if: Ryou hear banging noises. Rthe vehicle starts to shake. Ryou see smoke and smell rubber. RESP® is intervening constantly. Rthere are tears in the sidewalls of the tire. After driving in emergency mode, have the wheel rims checked at a qualified specialist workshop with regard to their further use. The defective tire must be replaced in every case.

i When replacing one or all tires, make sure

that you only use tires marked MOExtended. Also ensure that they are of the specified size for the vehicle.

Battery Important safety notes Special tools and expert knowledge are required when working on the battery, e.g. removal and installing. You should therefore have all work involving the battery carried out at a qualified specialist workshop. G WARNING Work carried out incorrectly on the battery can, for example, lead to a short circuit and damage your vehicle's electronic system. This can disrupt driving safety systems such as ABS (anti-lock braking system) or ESP® (Electronic Stability Program). RIf ABS malfunctions, the wheels can lock during braking. This limits the steerability of the vehicle when braking and the braking distance may increase. There is a risk of accident.

RIf ESP® malfunctions, the vehicle will not be stabilized if it starts to skid or a wheel starts to spin. There is a risk of accident.

You should therefore have all work involving the battery carried out at a qualified specialist workshop. G WARNING Comply with safety precautions and take protective measures when handling batteries.

Risk of explosion

Fire, open flames and smoking are prohibited when handling the battery. Avoid creating sparks.

Jump-starting

G WARNING Failure to follow these directions will cause damage to the electronic components, and can lead to a battery explosion and severe injury or death. Never lean over batteries while connecting or jump starting. You might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin or clothing. In case it does, immediately flush affected area with water, and seek medical help if necessary. A battery will also produce hydrogen gas, which is flammable and explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking, etc. Attempting to jump start a frozen battery can result in it exploding, causing personal injury. Read all instructions before proceeding. G WARNING Non-combusted fuel can collect in the exhaust system and ignite. There is a risk of fire. Avoid repeated and lengthy starting attempts.

! Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be

damaged by the non-combusted fuel.

Do not use a rapid charging device to start the vehicle. If your vehicle's battery is discharged, the engine can be jump-started from another vehicle or from a second battery using jumper cables. Observe the following points: RThe battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,

jump-start the vehicle using a second battery or a jump-starting device.

RYou may only jump-start the vehicle when the engine and catalytic converter are cold. RDo not start the engine if the battery is frozen. Let the battery thaw first. Rjump-starting may only be performed from batteries with a nominal voltage of 12 V. ROnly use jumper cables which have a sufficient cross-section and insulated terminal clamps. RIf the battery is fully discharged, leave the battery that is being used to jump-start connected

for a few minutes before attempting to start. This charges the empty battery a little.

RMake sure that the two vehicles do not touch. Make sure that: Rthe jumper cables are not damaged. Rbare parts of the terminal clamp do not come into contact with other metal parts while the

jumper cables are connected to the battery.

Rthe jumper cables cannot come into contact with parts such as the V-belt pulley or the fan.

These parts move when the engine is started and while it is running.

X Secure the vehicle by applying the electric parking brake. X Shift the transmission to position P. X Switch off all electrical consumers (e.g. radio, blower, etc.). X Open the hood (Y page 420).

Fuses Important safety notes G WARNING Only use fuses that have been approved for Mercedes-Benz vehicles and that have the correct fuse rating for the systems concerned. Do not attempt to repair or bridge faulty fuses. Using fuses that have not been approved or attempting to repair or bridge faulty fuses could cause the fuse to be overloaded and result in a fire. Have the cause traced and rectified at a qualified specialist workshop.

The fuses in your vehicle serve to close down faulty circuits. If a fuse blows, all the components on the circuit and their functions stop operating. Blown fuses must be replaced with fuses of the same rating, which you can recognize by the color and value. The fuse ratings are listed in the fuse allocation chart. If a newly inserted fuse also blows, have the cause traced and rectified at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. ! Only use fuses that have been approved

for Mercedes-Benz vehicles and which have the correct fuse rating for the system concerned. Otherwise, components or systems could be damaged.

Useful information

i This Operator's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety- related systems and functions.

i Please read the information on qualified

specialist workshops (Y page 29).

Important safety notes

G WARNING If wheels and tires of the wrong size are used, the wheel brakes or suspension components may be damaged. There is a risk of accident. Always replace wheels and tires with those that fulfill the specifications of the original part (designation, manufacturer, model). G WARNING A flat tire severely impairs the driving, steering and braking characteristics of the vehicle. There is a risk of accident. Tires without run-flat characteristics: Rdo not drive with a flat tire. Rimmediately replace the flat tire with your emergency spare wheel or spare wheel, or consult a qualified specialist workshop.

Tires with run-flat characteristics: Rpay attention to the information and

warning notices on MOExtended tires (tires with run-flat characteristics).

Accessories that are not approved for your vehicle by Mercedes-Benz or are not being used correctly can impair the operating safety.

Before purchasing and using non-approved accessories, visit a qualified specialist workshop and inquire about: Rsuitability Rlegal stipulations Rfactory recommendations Information on the dimensions and types of wheels and tires for your vehicle can be found in the "Wheel/tire combinations" section (Y page 477). Information on air pressure for the tires on your vehicle can be found: Ron the vehicle's Tire and Loading Information placard on the B-pillar

Ron the tire pressure label on the fuel filler

flap

Rin the "Tire pressure" section Pay special attention to the country-specific requirements for tire approval. These requirements can stipulate a specific tire type for your vehicle. Furthermore, the use of certain tire types in certain regions and areas of operation can be highly beneficial. You can find further information regarding tires at specialist tire retailers, at qualified specialist workshops or at any authorized Mercedes- Benz Center. i Further information on wheels and tires can be obtained at any qualified specialist workshop.

Operation Information on driving RIf the vehicle is heavily loaded, check the

tire pressures and correct them if necessary.

RWhile driving, pay attention to vibrations,

noises and unusual handling characteristics, e.g. pulling to one side. This may indicate that the wheels or tires are damaged. If you suspect that a tire is defective, reduce your speed immediately. Stop the vehicle as soon as possible to

Operation 455

check the wheels and tires for damage. Hidden tire damage could also be causing the unusual handling characteristics. If you find no signs of damage, have the tires and wheels checked at a qualified specialist workshop.

RWhen parking your vehicle, make sure that the tires do not get deformed by the curb or other obstacles. If it is necessary to drive over curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Otherwise, the tires, particularly the sidewalls, may be damaged.

approved by Mercedes-Benz for your vehicle. Do not use any other valve caps or systems, e.g. tire pressure monitoring systems. Regularly check the pressure of all the tires particularly prior to long trips. Adjust the tire pressure as necessary (Y page 458). Observe the notes on the emergency spare wheel (Y page 437). The service life of tires depends on the following factors amongst other things: RDriving style RTire pressure RDistance covered

Regular checking of wheels and tires G WARNING Damaged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle. There is a risk of accident. Check the tires regularly for signs of damage and replace any damaged tires immediately.

Regularly check the wheels and tires of your vehicle for damage at least once a month, as well as after driving off-road or on rough roads. Damaged wheels can cause a loss of tire pressure. Pay particular attention to damage such as: Rcuts in the tires Rpunctures Rtears in the tires Rbulges on tires Rdeformation or severe corrosion on wheels Regularly check the tire tread depth and the condition of the tread across the whole width of the tire (Y page 455). If necessary, turn the front wheels to full lock in order to inspect the inner side of the tire surface. All wheels must have a valve cap to protect the valve against dirt and moisture. Do not mount anything onto the valve other than the standard valve cap or other valve caps

Important safety notes on the tire tread G WARNING Insufficient tire tread will reduce tire traction. The tire is no longer able to dissipate water. This means that on wet road surfaces, the risk of hydroplaning increases, in particular where speed is not adapted to suit the driving conditions. There is a risk of accident. If the tire pressure is too high or too low, tires may exhibit different levels of wear at different locations on the tire tread. Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tires. Minimum tire tread depth for: RSummer tires: â in (3 mm) RM+S tires: ã in (4 mm) For safety reasons, replace the tires before the legally prescribed limit for the minimum tire tread depth is reached.

Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread. They are visible once the tread depth is approximately á in (1.6 mm). If this is the case, the tire is so worn that it must be replaced.

456 Winter operation

Bar indicator : for tread wear is integrated into the tire tread.

Selecting, mounting and replacing tires ROnly mount tires and wheels of the same

type and make. Exception: it is permissible to install a different type or make in the event of a flat tire. Observe the "MOExtended tires (tires with run-flat characteristics" section (Y page 441).
