into place.

X Clean the windshield and the wiper blade

inserts with a clean cloth and mild detergent solution.

X Use a soft, clean cloth and a mild window cleaning solution on all outside and inside glass surfaces. An automotive glass cleaner is recommended.

! Fold the windshield wiper arms back onto the windshield before turning the SmartKey in the starter switch. Hold on to the wiper when folding the wiper arm back. If released, the force of the impact from the tensioning spring could crack the windshield.

! To clean the window interior, do not use a dry cloth, abrasives, solvents or cleaners containing solvents. Do not touch the inside of the front, rear or side windows with hard objects such as an ice scraper or ring. Doing so may damage the windows.

Light alloy wheels If possible, clean wheels once a week. X Use Mercedes-Benz approved Wheel Care,

a soft bristle brush and a strong spray of water for cleaning the light alloy wheels. ! Only use acid-free cleaning materials.

Acid may cause corrosion or damage the clear coat.

! The vehicle should not be parked for an extended period of time immediately after it has been cleaned. This applies especially after the wheel rims have been cleaned with wheel rim cleaner. Wheel rim cleaners can lead to increased corrosion of the brake disks and brake pads. Non-approved wheel cleaners may also damage the wheel paint if the vehicle is not driven after cleaning.

Vehicle care 191

Therefore, the vehicle’s brake system should always be warmed-up before it is parked after cleaning. 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.

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

X Wipe with a cloth moistened in a lukewarm

solution. The surface may temporarily change color. If this is the case, wait for it to dry. G Warning! Do not use cleaners or cockpit care sprays containing solvents to clean the cockpit or the steering wheel. Cleaners containing solvents will make the surface porous and vehicle occupants could suffer serious injuries from plastic parts coming loose in the event of air bag deployment.

! Do not use oil, wax or scouring agents.

Otherwise you may scratch or damage the surface.

Hard plastic trim items X Use Mercedes-Benz approved Interior Care on a soft, lint-free cloth and apply with light pressure.

COMAND display ! You must switch off the COMAND display

and allow it to cool prior to cleaning.

! Do not use any liquids or cleaning agents.

These can damage or even destroy the audio display screen.

! To avoid damage to leather upholstery:

RWipe with light pressure only. RDo not clean with abrasive cleaning

agents such as scouring milk or powder.

RDo not soak the leather upholstery.

As leather is a natural product, it could otherwise harden or become porous. RExercise particular care when cleaning

perforated leather as its underside should not become wet.

Wood trims X Only use water and a damp cloth to clean

wood trims in your vehicle.

! Do not use solvents like tar remover or wheel cleaner nor polishes or waxes as these may be abrasive.

Chrome-plated exhaust tip Regular cleaning and care of chrome-plated exhaust tips will help to maintain their shine and the classy appearance. X Use Mercedes-Benz approved Chrome

Polishing Paste each time the vehicle has been washed, especially during the winter.

! Do not use alkaline cleaners such as

wheel cleaners as they could cause corrosion.

In a crash they may not be able to provide adequate protection.

Upholstery Using aftermarket seat covers or wearing clothing that have the tendency to give off coloring (e.g. when wet, etc.) may cause the upholstery to become permanently discolored. By lining the seats with a proper intermediate cover, contact-discoloration will be prevented. Leather upholstery Please note that leather upholstery is a natural product and is therefore subject to a natural aging process. Leather upholstery may also react to certain ambient influences such as high humidity or high temperature by showing wrinkles for example.

G Warning! Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up and possibly a fire.

G Warning! Follow recommended tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely 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 comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.

Display messages h Tire Pres. Check Tires

Possible causes/consequences and X Solutions The tire pressure in one or more tires is already below the minimum value. X Carefully bring the vehicle to a halt, avoiding abrupt

steering and braking maneuvers.

X Check and adjust tire pressure as required. X If necessary, change the wheel (Y page 232).

G Warning! Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up and possibly a fire.

G Warning! Follow recommended tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely 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 comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.

The BAS, the EBB, the ESP® and the 4-ETS are also switched off (see messages in multifunction display). The brake system is still functioning normally but without the systems specified above available. If the ABS control unit is malfunctioning, other systems such as the navigation system or the automatic transmission may also be malfunctioning. X Continue driving with added caution. Wheels may lock during

hard braking, reducing steering capability.

X Read and observe messages that may appear in the

multifunction display (Y page 196).

X Have the system checked at an authorized Mercedes-Benz

Center as soon as possible.

Failure to follow these instructions increases the risk of an accident. The ABS has switched off due to insufficient power supply. The battery might not be charged sufficiently. When the voltage is above the required value again, the ABS is operational again and the ABS indicator lamp should go out. X If the ABS indicator lamp does not go out: Have the alternator
