Replacing bulbs Important safety notes Xenon bulbs G DANGER Xenon bulbs carry a high voltage. You could get an electric shock and be seriously or even fatally injured if you touch the electric contacts on Xenon bulbs. Therefore, never remove the cover from Xenon bulbs. Do not change the Xenon bulbs yourself, but have them replaced at a qualified workshop.

If your vehicle is equipped with Xenon bulbs, you can recognize this by the following: the cone of light from the Xenon bulbs moves from the top to the bottom and back again when you start the engine. For this to be

Other bulbs G WARNING Bulbs and lamps can become very hot. For this reason, allow them to cool down before changing them. Otherwise, you could burn yourself when you touch them. Keep bulbs out of the reach of children. Otherwise, they could, for example, damage the bulbs and injure themselves. Never use a bulb which has been dropped. Such a bulb may explode and injure you. Halogen bulbs are pressurized and could explode when you change them, especially if they are very hot. You should therefore wear eye protection and gloves when you are changing them.

There are bulbs other than the Xenon bulbs that you cannot replace. Replace only the bulbs listed (Y page 132). Have the bulbs that you cannot replace yourself changed at a qualified specialist workshop. If you require assistance changing bulbs, consult a qualified specialist workshop. Do not touch the glass tube of new bulbs with your bare hands. Even minor contamination can burn into the glass surface and reduce the service life of the bulbs. Always use a lint- free cloth or only touch the base of the bulb when installing. Only use bulbs of the correct type. If the new bulb still does not light up, consult a qualified specialist workshop. Bulbs and lamps are an important aspect of vehicle safety. You must therefore make sure that these function correctly at all times. Have the headlamp setting checked regularly.

Windshield wipers Switching the windshield wipers on/ off G WARNING The windshield will not longer be wiped properly if the wiper blades are worn. This could prevent you from observing the traffic conditions, thereby causing an accident. Replace the wiper blades twice a year, ideally in spring and fall.

! Do not operate the windshield wipers when the windshield is dry, as this could damage the wiper blades. Moreover, dust that has collected on the windshield can scratch the glass if wiping takes place when the windshield is dry. If it is necessary to switch on the windshield wipers in dry weather conditions, always

use washer fluid when operating the windshield wipers.

! If the windshield wipers leave smears on the windshield after the vehicle has been washed in an automatic car wash, wax or other residues may be the reason for this. Clean the windshield using washer fluid after washing the vehicle in an automatic car wash.

! Intermittent wiping with rain sensor: due

to optical influences and the windshield becoming dirty in dry weather conditions, the windshield wipers may be activated inadvertently. This could then damage the windshield wiper blades or scratch the windshield. For this reason, you should always switch off the windshield wipers in dry weather.

138 Overview of climate control systems

i Ventilate the vehicle for a brief period

during warm weather, e.g. using the convenience opening feature (Y page 95). This will speed up the cooling process and the desired vehicle interior temperature will be reached more quickly.

i The integrated filter can filter out most

particles of dust, and completely filters out pollen. A clogged filter reduces the amount of air supplied to the vehicle interior. For this reason, you should always observe the interval for replacing the filter, which is specified in the Maintenance Booklet. Since the replacement interval depends on environmental conditions, e.g. heavy air pollution, the interval may be shorter than stated in the Maintenance Booklet.

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 Read the information on qualified specialist workshops: (Y page 27).

Overview of climate control systems Important safety notes G WARNING Observe the settings recommended on the following pages. The windows could otherwise fog up. This could prevent you from observing the traffic conditions, thereby causing an accident. G WARNING Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled replacement interval. A clogged filter will reduce the air volume to the interior and the windows could fog up, impairing visibility and endangering you and others. Have a clogged filter replaced as soon as possible at a qualified specialist workshop.

Climate control regulates the temperature and the humidity in the vehicle interior and filters undesirable substances out of the air. Climate control is only operational when the engine is running. The system only works optimally when the side windows and the roof are closed. The residual heat function can only be activated or deactivated with the ignition switched off (Y page 153).

Setting the air vents Important safety notes G WARNING Very hot or very cold air can flow from the air vents. This could cause burns or frostbite to bare skin in the immediate vicinity of the vents. Keep bare skin away from these air vents. If necessary, direct the airflow away to a different area of the vehicle interior.

In order to ensure the direct flow of fresh air through the air vents into the vehicle interior, please observe the following notes: Rkeep the air inlet grille on the hood and in

the engine compartment on the front- passenger side free of blockages, such as ice, snow or leaves.

Rnever cover the air vents or air intake grilles

in the vehicle interior.

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 Read the information on qualified specialist workshops: (Y page 27).

Breaking-in notes Important safety notes New and replaced brake pads and discs only reach their optimum braking effect after several hundred kilometers of driving. Compensate for this by applying greater force to the brake pedal.

The first 1,000miles (1,500 km) The more you look after the engine when it is new, the more satisfied you will be with its performance in the future. RYou should therefore drive at varying vehicle and engine speeds for the first 1,000 miles (1,500 km).

RAvoid heavy loads, e.g. driving at full

throttle, during this period.

RChange gear in good time, before the

tachometer needle is Ô of the way to the red area of the tachometer.

RDo not manually shift to a lower gear to

brake the vehicle.

RIf possible, do not depress the accelerator

pedal past the point of resistance (kickdown).

ROnly select shift ranges 3, 2 or 1 when

driving slowly, e.g. in mountainous terrain.

After 1,000 miles (1,500 km), you can increase the engine speed gradually and accelerate the vehicle to full speed. i You should also observe these notes on running in if the engine or parts of the drive train on your vehicle have been replaced.

i Always observe the respective speed

limits.

Driving Important safety notes G WARNING Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal. The operating and road safety of the vehicle is jeopardized. There is a risk of an accident. Make sure that all objects in the vehicle are stowed correctly, and that they cannot enter the driver's footwell. Install the floormats securely and as specified in order to ensure sufficient clearance for the pedals. Do not use loose floormats. G WARNING Unsuitable footwear can hinder correct usage of the pedals, e.g.: Rshoes with thick soles Rshoes with high heels Rslippers There is a risk of an accident. Wear suitable footwear to ensure correct usage of the pedals. G WARNING If you switch off the ignition while driving, safety-relevant functions are only available with limitations, or not at all. This could affect, for example, the power steering and the brake boosting effect. You will require considerably more effort to steer and brake. There is a risk of an accident. Do not switch off the ignition while driving.

G WARNING If the parking brake has not been fully released when driving, the parking brake can: Roverheat and cause a fire Rlose its hold function. There is a risk of fire and an accident. Release the parking brake fully before driving off.

! Warm up the engine quickly. Do not use the engine's full performance until it has reached operating temperature. Only shift the automatic transmission to the desired drive position when the vehicle is stationary. Where possible, avoid spinning the drive wheels when pulling away on slippery roads. You could otherwise damage the drive train.

KEYLESS-GO General notes RDo not keep the KEYLESS-GO key together:

- with electronic devices, e.g. a mobile

phone or another SmartKey

- with metallic objects, e.g. coins or metal

foil inside metallic objects, e.g. a metal case

This can impair the functionality of the KEYLESS-GO key.

Do not keep the KEYLESS-GO key in the temperature-controlled cup holder (Y page 339). Otherwise, the KEYLESS-GO key will not be recognized. Vehicles with KEYLESS-GO are equipped with a SmartKey featuring an integrated KEYLESS- GO function and a detachable Start/Stop button. The Start/Stop button must be inserted in the ignition lock and the SmartKey with the integrated KEYLESS-GO function must be in the vehicle. Pressing the Start/Stop button several times in succession corresponds to the different SmartKey positions in the ignition lock. This is only the case if you are not depressing the brake pedal. If you depress the brake pedal and press the Start/Stop button, the engine starts immediately. The Start/Stop button can be removed from the ignition lock. Then, you can insert the SmartKey into the ignition lock. i You do not have to remove the Start/Stop

button from the ignition lock when you leave the vehicle. You should, however, always take the SmartKey with you when leaving the vehicle. As long as the SmartKey is in the vehicle: Rthe vehicle can be started using the
