Switching off Press the left button for the minimum
speed.
Switching on
Press any button except▷Rear window defroster.▷Seat heating.
Microfilter/activated-charcoal filter
In external and recirculated air mode the mi‐
crofilter/activated charcoal filter filters dust,
pollen, and gaseous pollutants out of the air.
This filter should be replaced during scheduled
maintenance, refer to page 204, of your vehi‐
cle.

from the sun.▷Draft-free ventilation:
Adjust the vent to let the air flow past you.

Parked-car ventilation
The concept The parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if nec‐
essary.
The system can be switched on and off at any
external temperature, either directly or by us‐
ing two preset switch-on times. It remains
switched on for 30 minutes.
Open the vents to allow air to flow out.

Wheels and tiresVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Tire inflation pressure Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the pressure
Tires have a natural, consistent loss of pres‐
sure.
Check the tire inflation pressure regularly
Regularly check the tire inflation pres‐
sure, and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect tire pressures, a condition
that may not only compromise your vehicle's
driving stability, but also lead to tire damage
and the risk of an accident.◀
Tires heat up during driving, and the tire infla‐
tion pressure increases along with the temper‐
ature of the tire. The tire inflation pressure
specifications relate to cold tires or tires with
the ambient temperature.
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours.
After correcting the tire inflation pressure:▷Reinitialize the Flat Tire Monitor.▷Reinitialize the Tire Pressure Monitor.
Pressure specifications The tire inflation pressure table, refer to
page 188, contains all pressure specifications
for the specified tire sizes at the ambient tem‐
perature. Pressure specifications apply to ap‐
proved tire sizes and recommended tire
brands. This information can be obtained from
your service center.
To identify the correct tire inflation pressure,
please note the following:
▷Tire sizes of your vehicle.▷Maximum permitted driving speed.
Tire inflation pressures up to
100 mph/160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer
to page 188, and adjust as necessary.
These pressure values can also be found on
the tire inflation pressure label on the driver's
door pillar.
