Vehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehi‐
cle, 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 pressure.
Check the tire inflation pressure regularly
Regularly check the tire inflation pressure,
and correct it as needed: at least twice a month
and before a long trip. If you fail to observe this
precaution, you may be driving on tires with in‐
correct tire pressures, a condition that may not
only compromise your vehicle's driving stabil‐
ity, 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.
The displays of inflation devices may under-
read by up to 0.1bar, 2psi.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire Moni‐
tor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.
▷ Reinitialize the Flat Tire Monitor.
▷ Reinitialize the Tire Pressure Monitor.
Checking the inflation pressure of the
compact wheel
Located behind the bumper on the underside
of the vehicle is an opening for checking the
tire inflation pressure.
Pressure specifications
The tire inflation pressure table, refer to
page 169, 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.
