Tyre pressure monitoring*Introduction
The tyre pressure monitoring system constantly checks the
pressure of the tyres.The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument panel display. The system works
with the help of the ABS sensors in the wheels.
Please bear in mind that the tyre inflation pressure is also influenced by the
temperature of the tyre. Tyre pressure increases about 0.1 bar for each 10 °C
in tyre temperature increase. The tyre heats up while the vehicle is being
driven and the tyre pressure will rise accordingly. Therefore, you should only
adjust the tyre pressures when they are
cold (i.e. approximately at ambient
temperature).
To ensure that the tyre pressure monitoring system works reliably, you should
check and, if necessary, adjust the tyre pressures at regular intervals and
store the correct pressures (reference values) in the system.

WARNING
•Never adjust tyre pressure when the tyres are hot. This may damage or
even burst the tyres. Risk of accident!•An insufficiently inflated tyre flexes a lot more at high speeds and
causes significant heating of the tyre. Under these conditions, the tyre
bead may be released or the tyre may burst. Risk of accident!For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear.
Note
•Responsibility for ensuring that the tyres are correctly inflated remains
with the driver; the system can only provide assistance.•Pressure can only be adjusted when the tyres are at ambient
temperature.

Driving and the environment
200Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly at
higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at level
crossings or at traffic lights with a long red phase. The fuel saved after only
30 - 40 seconds is greater than the amount of fuel needed to restart the
engine.
The engine takes a very long time to warm up when it is running at idling
speed. Mechanical wear and pollutant emissions are also especially high
during this initial warm-up phase. It is therefore best to drive off immediately
after starting the engine. Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maximum
reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture .
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately four kilometres. This is why we recommend avoiding
short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressure is just 1 bar too low, fuel consumption can increase by as much as 5%. Due to the greater rolling resistance, under-inflation also increases
tyre wear
and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all year round as they increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h your vehicle will use about
12% more fuel as a result of the extra wind resistance caused by the roof rack
even when it is not in use.
Save electricity
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical components when you do not need them. Examples of
components that use a lot of electricity are: the fan at high speeds, the rear
window heating or the seat heaters*.
Note
•If you vehicle has Start-Stop, it is not recommended to disconnect this
function.•It is recommended to close the windows when driving at more than 60
km/h•Do not drive with your foot resting on the clutch pedal, as the pressure can
make the plate spin, more fuel will be used and it can burn the clutch plate
lining, causing a serious fault.

Significant tyre pressure lossThe tyre symbol
~ is displayed and indicates that the tyre pressure of at least
one tyre is insufficient.
- Stop the vehicle.
- Switch the engine off.
- Check the tyre(s).
- Change the tyre if necessary.
Tyre pressure monitoring (RKA+)*
The tyre pressure monitor display on the instrument panel
indicates if the pressure is too low.The tyre pressure monitoring system makes use of the ABS sensors to
compare the rolling circumference and the frequency characteristics of the wheels. If the rolling circumference or frequency characteristic changes on
one or more wheels, the tyre pressure warning lamp
~ will light up. The fault
will also be indicated by a warning buzzer. The position of the affected tyre
will also be shown (if only one tyre is affected) on the centre display of the
instrument panel.
The rolling circumference and frequency characteristics can change if:
•the tyre pressure is too low.•the tyre has suffered structural damage.•the wheels or the inflation pressures have been changed without initial-
ising the system (see Adjusting the tyre pressure settings).•there is a greater load on the wheels of one axle (e.g. if you are carrying
more passengers or luggage).•the road surface under the left wheels is different to the road surface
under the right wheels for a long period.•when driving with snow chains.
Adjusting the tyre pressure settings (initialising the tyre pressure
monitoring system)
After any incident regarding the wheels of your vehicle, e.g. after modify the
tyre pressure ⇒page 248 or after changing or swapping around wheels ⇒
page 180 - with the vehicle at a standstill and the engine running - press
⇒ fig. 186 . The yellow warning lamp
~ will light up. Hold the button down
for 2 seconds until the warning lamp goes out and an acoustic warning is
given. You can now release the button.
If the wheels are subjected to extreme stress (e.g. heavy load), the tyre pres-
sure must be increased to the recommended value for the maximum load
(see the adhesive label on the inside of the fuel tank flap) and then initialise
the system.
Tyre pressure warning lamp on
When you switch on the ignition, the tyre pressure warning lamp
~ will light
up for about 2 seconds. There is a fault in the system if the indicator stays on
permanently after switching on the ignition. The instrument panel also

Wear indicators
The original tyres on your vehicle have 1.6 mm high tread wear indicators
⇒
page 248, fig. 187 , running across the tread. Depending on the make,
there will be six to eight of them evenly spaced around the tyre. Markings on
the tyre sidewall (for instance the letters “TWI” or other symbols) indicate the
positions of the tread wear indicators. The minimum tread depth required by
law is 1.6 mm (measured in the tread grooves next to the tread wear indica-
tors). Worn tyres must be replaced. Different figures may apply in export
countries ⇒.
Tyre pressure
Under-inflation or over-inflation will reduce the life of the tyres considerably
and also impair the vehicle's handling. The inflation pressures are listed on a
sticker on the inside of the fuel tank flap.
Correct inflation pressures are very important, especially at high speeds. The
pressure should therefore be checked at least once a month and before
starting any long journey.
Tyre pressure monitoring (RKA+ )*
Monitoring of the tyre pressures is based on the tyre pressures you have
stored. The tyre pressure monitoring system cannot function as intended if
you store tyre pressure settings for a normal load, but then drive with the
vehicle fully laden. The tyre pressure must be adapted to the actual load and
stored accordingly in the tyre pressure monitoring system ⇒page 247.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisable
to cha nge t he m ar oun d as sh own ⇒ page 248, fig. 188. All the tyres will then
last for about the same time. Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which results
in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause excessive
wear on steering, suspension and tyres. A wheel must also be rebalanced
when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety of
the vehicle. If tyres show excessive wear, you should have the wheel align-
ment checked by an Authorised Service Centre.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!•The tyres must be replaced at the latest when the tread is worn down to
the tread wear indicators. Failure to do so could result in an accident. Worn
tyres do not grip well at high speeds on wet roads. There is also a greater
risk of aquaplaning.•At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.•If tyres show excessive wear, you should have the running gear checked
by an Authorised Service Centre.•Keep chemicals such as oil, fuel and brake fluid away from tyres.•Damaged wheels and tyres must be replaced immediately!For the sake of the environment
Under-inflated tyres will increase fuel consumption.

If and when
256Spare steel rim wheel
The spare steel rim wheel is carried in the wheel well under
the floor panel in the luggage compartment. It is only
intended for temporary use over short distances.Taking out the spare wheel
–Turn the plastic knob ⇒fig. 192 anti-clockwise.
– Take out the spare wheel.
Securing the defective wheel in the spare wheel well
– Place wheel in spare wheel well in the luggage compartment.
– Secure the wheel by turning plastic knob clockwise.
– Replace the floor panel before closing the tailgate.
Your vehicle can be factory-equipped with a spare steel wheel. The spare
wheel does not usually meet the same performance standards as the wheels
fitted on the vehicle because of the wheel/tyre dimensions, rubber composi-
tion, tread pattern, etc. Therefore, note the following restrictions:•The spare steel wheel is designed only for your vehicle model. Do not
attempt to mount the wheel on any vehicle but your own.•Your vehicle will have different driving characteristics when the spare
steel rim wheel is mounted ⇒ .•The spare wheel is only intended for temporary use after having a flat tyre.
Replace the spare wheel with a normal wheel that has the proper tyre dimen-
sions as soon as possible.•If the size of the spare steel rim wheel is different to that of the other
wheels, it is unlikely that snow chains suitable for the other wheels will fit it.WARNING
•After mounting the spare steel rim wheel, the tyre pressure must be
checked and corrected as soon as possible. The tyre pressure must corre-
spond to the vehicle load (consult the table containing the inflation pres-
sures). Otherwise there is danger of causing an accident. Use the highest
tyre pressure as indicated in the table.•Do not drive faster than 80 km/h, as higher speeds can cause an acci-
dent.•Avoid heavy acceleration, hard braking and fast cornering, as this could
cause an accident.
