i If the indicator lamp flashes green after successful programming, the garage door system is using a rolling code. After programming, you must synchronize the garage door opener integrated in the rear- view mirror with the receiver of the garage door system.

Synchronizing the rolling code Observe the "Important safety notes" (Y page 414). Your vehicle must be within reach of the garage door or exterior gate drive. Make sure that neither your vehicle nor any persons/ objects are present within the sweep of the door or gate. X Turn the SmartKey to position 2 in the

ignition lock.

X Press the program button of the door or

Problems when programming If you are experiencing problems programming the integrated garage door opener on the rear-view mirror, take note of the following instructions: RCheck the transmitter frequency of garage

door drive remote control A. This can usually be found on the back of the remote control. The integrated garage door opener is compatible with devices that have units which operate in the frequency range of 280to 433MHz.

RReplace the batteries in garage door remote control A. This increases the likelihood that garage door remote control A will transmit a strong and precise signal to the integrated garage door opener in the rear-view mirror.

RWhen programming, hold remote control

A at varying distances and angles from the button that you are programming. Try various angles at a distance between 2and 12 inches (5to 30 cm) or at the same angle but at varying distances.

Care Notes on care Regular care of your vehicle is a condition for retaining the quality in the long term. Use care products and cleaning agents recommended and approved by Mercedes- Benz. G WARNING Many cleaning products can be hazardous. Some are poisonous, others are flammable. Always follow the instructions on the particular container. Always open your vehicle's doors or windows when cleaning the inside. Never use fluids or solvents that are not designed for cleaning your vehicle. Always lock away cleaning products and keep them out of reach of children.

! For cleaning your vehicle, do not use any

of the following: Rdry, rough or hard cloths Rabrasive cleaning agents Rsolvents Rcleaning agents containing solvents Do not scrub. Do not touch the surfaces or protective films with hard objects, e.g. a ring or ice scraper. You could otherwise scratch or damage the surfaces and protective film. H Environmental note Dispose of empty packaging and cleaning cloths in an environmentally responsible manner.

! Do not park the vehicle for an extended period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause increased corrosion of the brake discs and brake pads/linings. For this reason, you should drive for a few minutes after cleaning. Braking heats the brake discs and the brake pads/linings, thus drying them. The vehicle can then be parked.

Exterior care Automatic car wash G WARNING Braking efficiency is reduced after washing the vehicle. This could cause an accident. For this reason, you must drive particularly carefully after washing the vehicle until the brakes have dried.

You can wash the vehicle in an automatic car wash from the very start. ! It is preferable to use car washes with

adjustable19 high-pressure precleaning. In car washes that use high water pressures, there is a risk that a small amount of water may leak into the vehicle.

! Never clean your vehicle in a Touchless Automatic Car Wash as these use special cleaning agents. These cleaning agents can damage the paintwork or plastic parts.

If the vehicle is very dirty, pre-wash it before cleaning it in an automatic car wash. ! In car washes with a towing mechanism, make sure that the automatic transmission is in transmission position N, otherwise the vehicle could be damaged. RVehicles with a SmartKey:

Do not remove the SmartKey from the ignition lock. Do not open the driver's door or front-passenger door when the engine is switched off. Otherwise, the

automatic transmission selects park position P automatically and locks the wheels. You can prevent this by shifting the automatic transmission to N beforehand.

RVehicles with KEYLESS-GO:

Do not open the driver's door or front- passenger door when the engine is switched off. Otherwise, the automatic transmission selects park position P automatically and locks the wheels.

Observe the following to make sure that the automatic transmission stays in position N: X Make sure the vehicle is stationary and the

ignition is switched off.

X Turn the key to position 2(Y page 273) in

the ignition lock. Use the SmartKey instead of the Start/ Stop button on vehicles with KEYLESS-GO.

X Depress and hold the brake pedal. X Shift the automatic transmission to

position N.

X Release the brake pedal. X Release the electric parking brake. X Switch off the ignition and leave the

SmartKey in the ignition lock.

! Make sure that:

Rthe side windows and the sliding sunroof

are fully closed.

Rthe ventilation/heating is switched off

(the OFF button has been pressed).

Rthe windshield wiper switch is in position

0.

Otherwise, the vehicle might be damaged. After using an automatic car wash, wipe off wax from the windshield and the wiper blades. This will prevent smears and reduce wiping noises caused by residue on the windshield.

Washing by hand In some countries, washing by hand is only allowed at specially equipped washing bays.

Observe the legal requirements in all countries concerned. X Do not use hot water and do not wash the

vehicle in direct sunlight.

X Use a soft sponge to clean. X Use a mild cleaning agent, such as a car shampoo approved by Mercedes-Benz.

X Thoroughly hose down the vehicle with a

gentle jet of water.

X Do not point the water jet directly towards

the air inlet.

X Use plenty of water and rinse out the

sponge frequently.

X Rinse the vehicle with clean water and dry

thoroughly with a chamois.

X Do not let the cleaning agent dry on the

paintwork.

When using the vehicle in winter, remove all traces of road salt deposits carefully and as soon as possible.

Power washers G WARNING Do not use power washers with circular-jet nozzles (dirt grinders) to clean your vehicle, in particular the tires. You could otherwise damage the tires and cause an accident.

! Always maintain a distance of at least

11.8 in (30 cm) between the vehicle and the power washer nozzle. Information about the correct distance is available from the equipment manufacturer. Move the power washer nozzle around when cleaning your vehicle. Do not aim directly at any of the following: Rtires Rdoor gaps, roof gaps, joints, etc. Relectrical components Rbattery Rconnectors Rlights Rseals

Rtrim Rventilation slots Damaged seals or electrical components can lead to leaks or failures.

Cleaning the wheels ! Do not use acidic wheel cleaning products to remove brake dust. This could damage wheel bolts and brake components.

! Do not park the vehicle for an extended period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause increased corrosion of the brake discs and brake pads/linings. For this reason, you should drive for a few minutes after cleaning. Braking heats the brake discs and the brake pads/linings, thus drying them. The vehicle can then be parked.

Cleaning the paintwork Scratches, corrosive deposits, areas affected by corrosion and damage caused by inadequate care cannot always be completely repaired. In such cases, visit a qualified specialist workshop. X Remove dirt immediately, where possible,

while avoiding rubbing too hard.
