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

Matte finish care ! 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). Always have paintwork repairs performed at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.

! Do not use wash programs with a hot wax

treatment under any circumstances.

Observe these notes if your vehicle has a clear matte finish. This will help you to avoid damage to the paintwork due to incorrect treatment. These notes also apply to light alloy wheels with a clear matte finish. i The vehicle should preferably be washed by hand using a soft sponge, car shampoo and plenty of water.

MOExtended tires (tires with run-flat properties) General notes 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. The affected tire must not show any clearly visible damage. You can recognize MOExtended tires by the MOExtended marking which appears on the sidewall of the tire. You will find this marking next to the tire size designation, the load- bearing capacity and the speed index (Y page 351). MOExtended tires may only be used in conjunction with an active tire pressure loss warning system or with an active tire pressure monitor. If the pressure loss warning message appears in the multifunction display: RObserve the instructions in the display

messages (Y page 258).

RCheck the tire for damage. RIf driving on, observe the following notes. The maximum driving distance is approximately 50 miles (80 km) when the vehicle is partially laden and approximately 18 miles (30 km) when the vehicle is fully laden.

322 Battery (vehicle)

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. You must not exceed a maximum speed of 50 mph (80 km/h). i When replacing one or all tires, make sure

that you use only tires: Rof the size specified for the vehicle and Rmarked "MOExtended" If a tire has gone flat and cannot be replaced with a MOExtended tire, a standard tire may be used as a temporary measure. Make sure that you use the proper size and type (summer or winter tire).

Important safety notes 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.

Battery (vehicle) 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 lead, for example, to a short circuit and thus damage the vehicle electronics. This can lead to function restrictions applying to safety-relevant systems, e.g. the lighting system, ABS (anti-lock braking system) or ESP® (Electronic Stability Program). The operating safety of your vehicle may be restricted. You could lose control of the vehicle, for example: Rbraking Rin the event of abrupt steering maneuver and/or when the vehicle's speed is not adapted to the road conditions

There is a risk of an accident. In the event of a short circuit or a similar incident, contact a qualified specialist workshop immediately. Do not drive any further. You should have all work involving the battery carried out at a qualified specialist workshop. G WARNING Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explosive gases of a battery. There is a risk of an explosion.

Before handling the battery, touch the vehicle body to remove any existing electrostatic build-up.

The highly flammable gas mixture forms when charging the battery as well as when jump- starting. Always make sure that neither you nor the battery is electrostatically charged. A build- up of electrostatic charge can be caused, for example: Rby wearing clothing made from synthetic

fibers

Rdue to friction between clothing and seats Rif you push or pull the battery across the

carpet or other synthetic materials Rif you wipe the battery with a cloth G WARNING During the charging process, a battery produces hydrogen gas. If a short circuit occurs or sparks are created, the hydrogen gas can ignite. There is a risk of an explosion. RMake sure that the positive terminal of a

connected battery does not come into contact with vehicle parts.

RNever place metal objects or tools on a

battery.

RIt is important that you observe the

described order of the battery terminals when connecting and disconnecting a battery.

over the battery. Keep children away from batteries. Wash battery acid immediately with water and seek medical attention. H Environmental note

Batteries contain dangerous substances. It is against the law to dispose of them with the household rubbish. They must be collected separately and recycled to protect the environment. Dispose of batteries in an environmentally friendly manner. Take discharged batteries to a qualified specialist workshop or a special collection point for used batteries.

! Have the battery checked regularly at a

qualified specialist workshop. Observe the service intervals in the Maintenance Booklet or contact a qualified specialist workshop for more information.

! You should have all work involving the

battery carried out at a qualified specialist workshop. In the exceptional case that it is necessary for you to disconnect the battery yourself, make sure that: Ryou switch off the engine and remove the

SmartKey. On vehicles with KEYLESS- GO, ensure that the ignition is switched off. Check that all the indicator lamps in the instrument cluster are off. Otherwise, electronic components, such as the alternator, may be damaged.

Ryou first remove the negative terminal clamp and then the positive terminal clamp. Never swap the terminal clamps. Otherwise, the vehicle's electronic system may be damaged.

Rthe transmission is locked in position P

after disconnecting the battery. The vehicle is secured against rolling away. You can then no longer move the vehicle.

324 Battery (vehicle)

The battery and the cover of the positive terminal clamp must be installed securely during operation.

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. Battery acid is caustic. Avoid contact with skin, eyes or clothing. Wear suitable protective clothing, especially gloves, apron and faceguard. Rinse any acid spills immediately with clear water. Contact a physician if necessary. Wear eye protection.

Keep children away.

Observe this Operator's Manual.

For safety reasons, Mercedes-Benz recommends that you only use batteries which have been tested and approved for your vehicle by Mercedes-Benz. These batteries provide increased impact protection to prevent vehicle occupants from suffering acid burns should the battery be damaged in the event of an accident. In order for the battery to achieve the maximum possible service life, it must always be sufficiently charged. The vehicle battery, like other batteries, can discharge over time if you do not use the vehicle. In this case, have the battery

disconnected at a qualified specialist workshop. You can also charge the battery with a charger recommended by Mercedes- Benz. Contact a qualified specialist workshop for further information. Have the battery condition of charge checked more frequently if you use the vehicle mainly for short trips or if you leave it standing idle for a lengthy period. Consult a qualified specialist workshop if you wish to leave your vehicle parked for a long period of time. i Remove the SmartKey if you park the vehicle and do not require any electrical consumers. The vehicle will then use very little energy, thus conserving battery power.

i If the power supply has been interrupted, e.g. if you reconnect the battery, you will have to: Rset the clock. Information on setting the

clock can be found in the separate operating instructions. On vehicles with COMAND and a navigation system, the clock is set automatically.

Rreset the function for folding the exterior mirrors in/out automatically, by folding the mirrors out once (Y page 110).

Charging the battery G WARNING During charging and jump-starting, explosive gases can escape from the battery. There is a risk of an explosion. Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient ventilation while charging and jump-starting. Do not lean over a battery. G WARNING Battery acid is caustic. There is a risk of injury. Avoid contact with the skin, eyes or clothing. Do not inhale any battery gases. Do not lean

over the battery. Keep children away from batteries. Wash battery acid immediately with water and seek medical attention. G WARNING A discharged battery can freeze at temperatures below freezing point. When jump-starting the vehicle or charging the battery, gases can escape from the battery. There is a risk of an explosion. Allow the frozen battery to thaw out before charging it or jump-starting.

! Only use battery chargers with a

maximum charging voltage of 14.8 V.

! Only charge the battery using the jump-

starting connection point.

The jump-starting connection point is in the engine compartment (Y page 326). X Open the hood (Y page 306). X Connect the battery charger to the positive

terminal and ground point in the same order as when connecting the donor battery in the jump-starting procedure (Y page 326).

If, at low temperatures, the indicator lamps/ warning lamps in the instrument cluster do not light up, it is highly likely that the discharged battery has frozen. In this case, you may neither charge the battery nor jump- start the vehicle. The service life of a thawed- out battery may be shorter. The starting characteristics may be impaired, especially at low temperatures. Have the thawed-out battery checked at a qualified specialist workshop. Never charge a battery still installed in the vehicle unless a battery charger unit approved by Mercedes-Benz is being used. A battery charger unit specially adapted for Mercedes-Benz vehicles and tested and approved by Mercedes-Benz is available as an accessory. It permits the charging of the battery in its installed position. Contact an authorized Mercedes-Benz Center for further

Jump-starting

For the jump-starting procedure, use only the jump-starting connection point, consisting of a positive terminal and an earth point, in the engine compartment. G WARNING Battery acid is caustic. There is a risk of injury. Avoid contact with the skin, eyes or clothing. Do not inhale any battery gases. Do not lean over the battery. Keep children away from batteries. Wash battery acid immediately with water and seek medical attention. G WARNING During charging and jump-starting, explosive gases can escape from the battery. There is a risk of an explosion. Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient ventilation while charging and jump-starting. Do not lean over a battery. G WARNING During the charging process, a battery produces hydrogen gas. If a short circuit occurs or sparks are created, the hydrogen gas can ignite. There is a risk of an explosion. RMake sure that the positive terminal of a connected battery does not come into contact with

vehicle parts.

RNever place metal objects or tools on a battery. RIt is important that you observe the described order of the battery terminals when connecting

and disconnecting a battery.

RWhen jump-starting, make sure that the battery poles with identical polarity are connected. RIt is particularly important to observe the described order when connecting and disconnecting

the jumper cables.

RNever connect or disconnect the battery terminals while the engine is running. G WARNING A discharged battery can freeze at temperatures below freezing point. When jump-starting the vehicle or charging the battery, gases can escape from the battery. There is a risk of an explosion. Allow the frozen battery to thaw out before charging it or jump-starting.

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

damaged by the non-combusted fuel.

Do not start the vehicle using a rapid charging device. 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 exhaust system are cold. RDo not start the engine if the battery is frozen. Let the battery thaw first.

Jump-starting 327

ROnly jump-start from batteries with a 12 V voltage rating. 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 battery slightly.

RMake sure that the two vehicles do not touch. Make sure that: Rthe jumper cables are not damaged. Rwhen the jumper cables are connected to the battery, uninsulated sections of the terminal

clamp do not come into contact with other metal sections.

Rthe jumper cables cannot come into contact with parts which can move when the engine

is running, such as the V-belt pulley or the fan.

X Slide cover : of positive terminal ; in the direction of the arrow. X Connect positive terminal ; on your vehicle to positive terminal = of donor battery B using the jumper cable, always begin with positive terminal ; on your own vehicle first.

X Start the engine of the donor vehicle and run it at idling speed. X Connect negative terminal ? of donor battery B to ground point A of your vehicle using

the jumper cable, connecting the jumper cable to battery of other vehicle B first.

X Start the engine. X Before disconnecting the jumper cables, let the engine run for several minutes.

328 Towing and tow-starting

X First, remove the jumper cables from earth point A and negative terminal ?, then from positive clamp ; and positive terminal =. Begin each time at the contacts on your own vehicle first.

X Close cover : of positive clamp ; after removing the jumper cables. X Have the battery checked at a qualified specialist workshop. i Jump-starting is not considered to be a normal operating condition. i Jumper cables and further information regarding jump-starting can be obtained at any

qualified specialist workshop.

Towing and tow-starting Important safety notes G WARNING Functions relevant to safety are restricted or no longer available if: Rthe engine is not running. Rthe brake system or the power steering is

malfunctioning.

Rthere is a malfunction in the voltage supply

or the vehicle's electrical system.

If your vehicle is being towed, much more force may be necessary to steer or brake. There is a risk of an accident. In such cases, use a tow bar. Before towing, make sure that the steering moves freely. G WARNING If the weight of the vehicle to be towed or tow- started is greater than the permissible gross weight of your vehicle: Rthe towing eye could detach itself Rthe vehicle/trailer combination could

rollover.

There is a risk of an accident. When towing or tow-starting another vehicle, its weight should not be greater than the permissible gross weight of your vehicle.

Information on your vehicle's gross vehicle weight rating can be found on the vehicle identification plate (Y page 372).

Fuses Important safety notes G WARNING If you manipulate or bridge a faulty fuse or if you replace it with a fuse with a higher amperage, the electric cables could be overloaded. This could result in a fire. There is a risk of an accident and injury. Always replace faulty fuses with the specified new fuses having the correct amperage.

! 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.

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.

Before changing a fuse X Secure the vehicle against rolling away

(Y page 167).

X Switch off all electrical consumers. X Turn the SmartKey to position 0 in the

ignition lock and remove it (Y page 147).
