the driver's field of view.

Tyre designations

E.g. 215/60 R 16 95 H
215 = Tyre width, mm
60 = Cross-section ratio (tyre
height to tyre width), %
R = Belt type: Radial
RF = Type: RunFlat
16 = Wheel diameter, inches
95 = Load index e.g. 95 is
equivalent to 690 kg
H = Speed code letter
Speed code letter:
Q = up to 100 mph (160 km/h)
S = up to 112 mph (180 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 168 mph (270 km/h)

Tyre pressure

Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Unscrew the valve cap.
Tyre pressure 3 215 and on the label
on the front left door frame.
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.
Vehicle care
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to
tread separation and even to tyre
blow-out at high speeds.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Tyre pressure monitoring
system
The tyre pressure monitoring system
checks the pressure of all four wheels
once a minute when vehicle speed
exceeds a certain limit.
