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 Tyres of size 185/60 R 15 are only
approved as winter tyres.
Tyres of size 185/65 R 15 are only
approved as winter tyres on vehicles with a sports chassis. We recommend that you contact a workshop in order
to find out whether your vehicle is
equipped with a sports chassis.Winter tyres
Winter tyres improve driving safety attemperatures below 7 °C and should
therefore be fitted on all wheels.
Tyres of size 185/60 R 15,
185/65 R 15, 185/70 R 14,
195/55 R 16 and
205/50 R 16 are permitted as winter
tyres.
Tyres of size 195/60 R 15,
215/45 R 17 1)
and 225/35 R 18 must
not be used as winter tyres.
Run-flat winter tyres may only be
used on factory approved alloy
wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.

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 deflation detection system.
Remove the valve cap key from the
fuel filler flap and use it to unscrew the valve cap.
Tyre pressure 3 217 and on the label
on the inside of the fuel filler flap or on
the front right 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.
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.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 202.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 217.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.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.

174Vehicle careTyre pressure monitoring
system The vehicle may be fitted with a tyrepressure monitoring system or a tyre
deflation detection system 3 175.Caution
Modifications made to the tyre
pressure monitoring system
(TPMS) by anyone other than an
authorised service facility may
void authorisation to use the
system.
The tyre pressure monitoring system
checks the pressure of all four wheels once a minute when vehicle speed
exceeds a certain limit.
Caution
Tyre pressure monitoring system
warns only about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
Winter tyres or additional wheel sets
have to be fitted with sensors,
otherwise the system will not work
and the control indicator A illuminates
continuously.
If A lights up, stop as soon as
possible and inflate the tyres as
recommended 3 217.
After inflating, driving may be
required to extinguish A.
If A lights up at lower temperatures
and extinguishes after some driving,
this could be an early indicator for getting low pressure. Check tyre
pressure.
The tyre pressure monitoring system
malfunction indicator is combined
with the low tyre pressure controlindicator. If the system detects a
malfunction, the control indicator will
flash for approx. 1 minute and then
remain continuously illuminated. This sequence will continue upon
subsequent vehicle start‐ups as long as the malfunction exists.
A temporary spare wheel is not
equipped with a pressure sensor. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator A illuminates.
Operating electronic devices or being
near facilities using radio wave
frequencies similar to the tyre
pressure monitoring system could
cause the tyre pressure monitoring
system sensors to malfunction.
Tyre pressure monitoring system malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tyres or
wheels on the vehicle that prevent the tyre pressure monitoring system fromfunctioning properly. Always check
the tyre pressure monitoring system
malfunction control indicator after
replacing one or more tyres or wheels
