Wheels and tyres

Tyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb
when parking.
Regularly check the wheels for
damage. Seek the assistance of
a workshop in the event of damage or
unusual wear.
Tyres
Factory-fitted tyres are matched to
the chassis and offer optimum driving
comfort and safety.

Winter tyres

Winter tyres improve driving safety at
temperatures below 7 °C and should
therefore be fitted on all wheels.
Tyres of size 165/70 R 14
and 185/60 R 15 may be used as
winter tyres.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.

Tyre designations

E.g. 185/65 R 15 88 T
185 = Tyre width, mm
65 = Cross-section ratio (tyre
height to tyre width), %
R = Belt type: Radial
RF = Type: RunFlat
15 = Wheel diameter, inches
88 = Load index e.g. 88 is
equivalent to 567 kg
T = Speed code letter
Speed code letter:
Q = up to 160 km/h (100 mph)
S = up to 180 km/h (112 mph)
T = up to 190 km/h (118 mph)
H = up to 210 km/h (130 mph)
V = up to 240 km/h (150 mph)
W = up to 270 km/h (168 mph)
Vehicle care

Tyre pressure

Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel.
Tyre pressure 3 135 and the label
located on the driver's door pillar.
The tyre pressure data refers to cold
tyres. It applies to summer and winter
tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
