the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Power steering fluid
Caution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not
work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap/dipstick or
from entering the reservoir.
Power steering fluid level normally
does not need to be checked. If an
unusual noise sounds during steering or the power steering reacts
conspicuously, seek the assistance of
a workshop.

Vehicle care175Tyre 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 3 207 and on the label
on the driver's 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 3 207.
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.
Tyre pressure monitoring
system
The Tyre Pressure Monitoring
System (TPMS) uses radio and
sensor technology to check tyre
pressure levels.
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.
Page 178 of 219

176Vehicle care
The TPMS sensors monitor the air
pressure in the tyres and transmit tyre pressure readings to a receiver
located in the vehicle.
Each tyre, including the spare, should be checked monthly when cold and
inflated to the inflation pressure
recommended on the tyre pressure
label.
Control indicator w illuminates when
one or more tyres are significantly
under-inflated.
Check the tyre pressure as soon as
possible, and inflate them to the
recommended pressure 3 175.
When the system detects a malfunction, w will flash for approx.
one minute and then remain
continuously illuminated. This
sequence will continue upon
subsequent vehicle start-ups as long
as the malfunction exists.
When w is illuminated, the system
may not be able to detect or signal low
tyre pressure as intended.Tyre Pressure Monitoring
Operation
The TPMS is designed to warn the
driver when a low tyre pressure
condition exists. TPMS sensors are
mounted onto each tyre and wheel
assembly, excluding the spare tyre
and wheel assembly. The TPMS
sensors monitor the air pressure in
the tyres and transmit the tyre
pressure readings to a receiver
located in the vehicle.
When a low tyre pressure condition is
detected, w illuminates. Stop as soon
as possible and inflate the tyres to the
recommended tyre pressure 3 175.
Additionally a warning message or a
warning code is displayed in the
Driver Information Centre 3 94.
The low tyre pressure control
indicator and a warning message or
code come on at each ignition cycle
until the tyres are inflated to the
correct tyre pressure.
TPMS Malfunction Indicator and
Message Code
The TPMS will not function properly if
one or more of the TPMS sensors are missing or inoperable. When the
system detects a malfunction, w
flashes for approx. one minute and then illuminates. Additionally a
warning message or code is
displayed.
The indication by the TPMS
malfunction indicator and a warning
message or code will come on at each ignition cycle until the problem iscorrected. Some of the conditions
that can cause these to come on are:
■ One of the tyres has been replaced
with the spare tyre which does not
have a TPMS sensor.
Page 179 of 219

Vehicle care177
■ The TPMS sensor matchingprocess was not done or not
completed successfully after
rotating the tyres. The malfunction
light and the warning message or
code should go off after
successfully completing the sensor matching process. See "TPMS
Sensor Matching Process" later in
this section.
■ One or more TPMS sensors are missing or damaged. The warning
message or code and the
malfunction light should go off
when the TPMS sensors are
installed and the sensor matching
process is performed successfully.
Consult your workshop for service.
■ Replacement tyres or wheels do not match the original equipment
tyres or wheels. Tyres and wheels other than those recommended
could prevent the TPMS from
functioning properly.
■ Operating electronic devices or being near facilities using radio
wave frequencies similar to theTPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal
a low tyre condition. Consult your
workshop for service if the TPMS
malfunction light and a warning
message or code come on and stay on.
TPMS Sensor Matching
Process Each TPMS sensor has a unique
identification code. The identification
code must be matched to a new tyre/
wheel position after rotating the tyres
or replacing one or more of the TPMS
sensors. The TPMS sensor matching process should also be performed
after replacing a spare tyre with a
road tyre containing the TPMS
sensor.
The malfunction light and the warning
message or code should go off at the
next ignition cycle. The sensors are
matched to the tyre/wheel positions,
using a TPMS relearn tool, in the
following order: driver side front tyre,
passenger side front tyre, passengerside rear tyre, and driver side rear.
Consult your workshop for service or
to purchase a relearn tool. There are
two minutes to match the first tyre/
wheel position, and five minutes
overall to match all four tyre/wheel positions. If it takes longer, the
matching process stops and must be
restarted.
The TPMS sensor matching process
is:
1. Apply the parking brake.2. Turn the ignition on.
3. Use the MENU button on the turn
signal lever to select the Vehicle
Information Menu in the Driver
Information Centre (DIC).
4. Use the thumbwheel to scroll to the tyre pressure menu.
5. Press the SET/CLR button to
begin the sensor matching
process. A message requesting
acceptance of the process should
display.
