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. As it depends on environmental conditions, e.g. heavy air pollution, the interval may be shorter than stated in the Maintenance Booklet.
i It is possible that the dehumidification
function of the climate control system may be activated automatically an hour after the SmartKey has been removed. The vehicle is then ventilated for 30 minutes.

Notes on breaking-in a new vehicle 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).
RIdeally, for the first 1,000 miles (1,500 km),
drive in program E.
After 1,000 miles (1,500km), you can increase the engine speed gradually and bring the vehicle up to full speed. i You should also observe these notes on
breaking-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.

Starting the engine Important safety notes G WARNING Combustion engines emit poisonous exhaust gases such as carbon monoxide. Inhaling these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave the engine running in enclosed spaces without sufficient ventilation. G WARNING Flammable materials introduced through environmental influence or by animals can ignite if in contact with the exhaust system or parts of the engine that heat up. There is a risk of fire. Carry out regular checks to make sure that there are no flammable foreign materials in the engine compartment or in the exhaust system.
! Do not depress the accelerator pedal
when starting the engine.
i During a cold start, the engine runs at
higher speeds to enable the catalytic converter to reach its operating temperature. The sound of the engine may change during this time.
Automatic transmission X Shift the transmission to position P.
Transmission position display P is shown in the multifunction display.
i When the transmission is in position N, you can also start the engine with the brake pedal depressed.
Starting procedure X Turn the SmartKey to position 3 in the
ignition lock (Y page 135) and release it as soon as the engine is running.

Pulling away Automatic transmission i It is only possible to shift the transmission
from position P to the desired position if you depress the brake pedal. Only then can the parking lock be deactivated. If you do not depress the brake pedal, the DIRECT SELECT lever can still be moved but the parking lock remains engaged.
i If the transmission oil temperature is
below Ò4 ‡ (Ò20 † ), you can only shift from position P when the engine is running.
X Depress the brake pedal and keep it
depressed.
X Shift the transmission to position D or R. X Release the brake pedal. X Carefully depress the accelerator pedal.
The electric parking brake (Y page 150) is automatically released. The red ! indicator lamp in the instrument cluster goes out.
i The vehicle locks centrally once you have pulled away. The locking knobs in the doors drop down. You can open the doors from the inside at any time. You can also deactivate the automatic locking feature (Y page 198).
i Upshifts take place at higher engine
speeds after a cold start. This helps the catalytic converter to reach its operating temperature more quickly.
Hill start assist G WARNING After a short time, hill start assist will no longer brake your vehicle and it could roll away. There is a risk of an accident and injury. Therefore, quickly move your foot from the brake pedal to the accelerator pedal. Never leave the vehicle when it is held by hill start assist.
Hill start assist helps you when pulling away forwards or in reverse on an uphill gradient. It holds the vehicle for a short time after you have removed your foot from the brake pedal. This gives you enough time to move your foot from the brake pedal to the accelerator pedal and to depress it before the vehicle begins to roll. X Remove your foot from the brake pedal.
The vehicle is then held for about a second.
X Pull away. Hill start assist will not function if: Ryou are pulling away on a level road or on
a downhill gradient.
Rthe transmission is in position N. Rthe electric parking brake is applied. RESP® is malfunctioning. Further information on holding the vehicle stationary on uphill gradients (Y page 143).
ECO start/stop function Important safety notes G WARNING If the engine is switched off automatically and you exit the vehicle, the engine is restarted automatically. The vehicle may begin moving. There is a risk of accident and injury. If you wish to exit the vehicle, always turn off the ignition and secure the vehicle against rolling away.
General notes If the ¤ symbol is shown in the multifunction display, the ECO start/stop function switches the engine off automatically when the vehicle stops. The engine starts automatically when the driver wants to pull away again. The ECO start/stop function thereby helps you to reduce the fuel consumption and emissions of your vehicle.
The stop/start function is automatically activated each time you start the engine with the SmartKey. If the ECO start/stop function has been manually deactivated (Y page 138) or a malfunction has caused the system to be deactivated, the ¤ symbol is not displayed.
Automatic engine switch-off General notes The ECO start/stop function is operational and the ¤ symbol is displayed in the multifunction display, if: Rthe indicator lamp in the ECO button is lit
green.
Rthe outside temperature is within the
comfort range.

temperature.
Rthe set temperature for the vehicle interior
has been reached.
Rthe battery is sufficiently charged. Rthe system detects that the windshield is not fogged up when the air-conditioning system is switched on.
Rthe hood is closed. Rthe driver's door is closed and the driver's
seat belt is fastened.
If conditions for automatic engine switch-off have not been fulfilled, the ¤ symbol will not be shown. i All of the vehicle's systems remain active
when the engine has been stopped automatically.
i The engine can be switched off
automatically a maximum of four times (first stop and three subsequent stops) in succession. Automatic engine switch-off is possible again once the ECO symbol appears in the multifunction display.

Vehicles with automatic transmission If the vehicle is braked to a standstill in D or N, the ECO start/stop function switches off the engine automatically. i The HOLD function can be activated if the
engine has been switched off automatically. It is then not necessary to continue applying the brakes during the automatic stop phase. When you depress the accelerator pedal, the engine starts automatically and the braking effect of the HOLD function is deactivated.
Automatic engine start General notes The engine starts automatically if: Ryou switch off the ECO start/stop function
by pressing the ECO button. Ryou engage reverse gear R. Rthe vehicle starts to roll. Rthe brake system requires this. Rthe temperature in the vehicle interior
deviates from the set range.
Rthe system detects moisture on the windshield when the air-conditioning system is switched on.
