G WARNING Before programming the integrated remote control to a garage door opener or gate operator, make sure people and objects are out of the way of the device to prevent potential harm or damage. When programming a garage door opener, the door moves up or down. When programming a gate operator, the gate opens or closes. Do not use the integrated remote control with any garage door opener that lacks safety stop and reverse features as required by U.S. federal safety standards (this includes any garage door opener model manufactured before April 1, 1982). A garage door that cannot detect an object - signaling the door to stop and reverse - does not meet current U.S. federal safety standards. When programming a garage door opener, park vehicle outside the garage. Do not run the engine while programming the integrated remote control. Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide (CO), and inhaling it can cause unconsciousness and possible death.

X Check that the hood has engaged properly. If the hood can be raised slightly, it is not properly engaged. Open it again and close it with a little more force.

Radiator i Vehicles with a diesel engine: do not

cover the radiator, for example with a winter front or bug cover. Otherwise, the readings of the on-board-diagnostic system may be inaccurate. Some of these readings are required by law and must be accurate at all times.

Engine oil Notes on the oil level Depending on the driving style, the vehicle consumes up to 0.9 US qts. (0.8 l) of oil over a distance of 600 miles (1000 km). The oil consumption may be higher than this when the vehicle is new or if you frequently drive at high engine speeds.

Checking the oil level using the oil dipstick When checking the oil level: Rpark the vehicle on a level surface. Rthe engine should be switched off for

approximately five minutes if the engine is at normal operating temperature.

X Pull release lever : on the hood.

The hood is released.

Adding engine oil H Environmental note When adding oil, take care not to spill any. If oil enters the soil or waterways, it is harmful to the environment. G WARNING If engine oil comes into contact with hot engine parts, it may ignite and you could burn yourself. Do not spill any engine oil on hot engine parts.

! Use only engine oils and oil filters that

have been approved for vehicles equipped with a service system. A list of the engine oils and oil filters tested and approved in accordance with the Mercedes-Benz Specifications for Service Products can be called up by visiting http:// www.mbusa.com (USA only). More information about tested and approved engine oils and oil filters is available from any authorized Mercedes-Benz Center. Damage to the engine or exhaust system is caused by the following: Rusing engine oils and oil filters which

have not been specifically approved for the service system.

Rreplacing the engine oil or oil filter after the replacement interval required by the service system has elapsed Rusing engine oil additives.

Example: engine oil cap X Turn cap : counter-clockwise and remove

it.

X Add the amount of oil required. Fill carefully to the maximum mark on the oil dipstick. i Depending on the engine, the difference in quantity between the MIN mark and the MAX mark on the dipstick is approximately 1.6 to 2.1 US qt (1.5 to 2 l).

! Do not add too much oil. If the oil level is above the "max" mark on the dipstick, too much oil has been added. This can lead to

damage to the engine or the catalytic converter. Have excess oil siphoned off. For further information on engine oil, see (Y page 375). X Replace cap : on the filler neck and

Care Notes on care Regular care of your vehicle is a condition for retaining the quality in the long term.

306 Care

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. ! 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 SmartKey to position

2 (Y page 149) 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 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 Carefully remove all deposits of road salt as soon as possible when driving in winter. Also, clean the insides of the wheels when washing the underbody of the vehicle. X Do not use hot water and do not wash the

vehicle in direct sunlight.

X Use a soft car sponge for cleaning. X Use a gentle cleaning agent, e.g. a

Mercedes-Benz approved car shampoo.

X Wash down the vehicle with a gentle water

jet.

X Do not point the water jet directly at the air

inlets.

X Use plenty of water and rinse the sponge

frequently.

Care 307

X Rinse the vehicle with clean water and dry

it thoroughly with a chamois.

X Do not allow the cleaning agent to dry on

the paintwork.

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
