Your Authorised Service Centre can also be consulted to know if the vehicle
has been prepared for biodiesel use.
Things to note about RME fuel (biodiesel)
•The performance of a vehicle using biodiesel maybe somewhat reduced.•Fuel consumption of a vehicle using biodiesel may be slightly higher.•RME fuel is resistant to the cold down to approx. -10°C.•At temperatures below -10°C, we recommend using winter diesel fuel.•Your vehicle is designed to be refuelled with up to a maximum of 7%
blended biodiesel, in accordance with the DIN 51628 standard.Caution
•RME fuel can damage the fuel system in vehicles which are not suitably
adjusted.•If you refuel with biodiesel, please be sure that it conforms to the
DIN E 14.214 standard.•If you use biodiesel that does not meet the required standard, the fuel
filter could become clogged.Note
•In case of low exterior temperatures and a fuel biodiesel percentage of
higher than 50%, an increase in gas emission may occur during operation of
the independent heating.•The fuel filter may become clogged when fuel is changed to biodiesel. For
this reason, we recommend you that, when having run 300 or 400 km after a
fuel change, the fuel filter change must also be done. Also note the instruc-
tions in the Inspection and Maintenance plan.•If the vehicle is to remain parked for more than about two weeks, we
recommend filling the fuel tank with biodiesel and driving about 50 km in
order to avoid damage to the injection system.
Winter driving
Diesel can thicken in winter.Winter-grade diesel
When using summer-grade diesel fuel, difficulties may be experienced at
sub-zero temperatures because the fuel thickens due to wax separation.
Therefore, winter-grade diesel fuel is available in some countries during the
cold months. It can be used at temperatures as low as -22°C.
In countries with different climatic conditions the diesel fuel generally sold
has different temperature characteristics. Check with an Authorised Service
Centre or filling stations in the country concerned regarding the type of diesel
fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter pre-heater, making it well equipped for
operation in winter. This ensures that the fuel system remains operational to
approx. -24°C, provided you use winter-grade diesel which is safe to -15°C.
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24°C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (“thinners”, or similar additives) with diesel fuel.

when working on the battery.•Never touch the radiator fan while the engine is hot, as the fan could
start up suddenly.•Never open the expansion tank when the engine is hot. The cooling
system is under pressure.•Protect face, hands and arms from any hot steam or hot liquid coolant
released by covering the cap with a large, thick rag when opening the
expansion tank.•If any tests have to be performed with the engine running, there is an
extra safety risk from the rotating parts, such as the drive belts, alternator
and radiator fan, etc., and from the high-voltage ignition system.•Observe the following additional warnings if work on the fuel system or
the electrical system is necessary:
−Always disconnect the battery.
− Do not smoke.
− Never work near open flames
− Always keep an approved fire extinguisher immediately available.Caution
When topping up fluids, make sure the correct fluid is put into the correct
filler opening. This can otherwise cause serious malfunctions or engine
damage.
For the sake of the environment
Inspect the ground underneath your vehicle regularly so that any leaks are
detected at an early stage. If you find spots of oil or other fluids, have your
vehicle inspected in the garage.

Brake fluidChecking the brake fluid level
The brake fluid level can be checked at a glance.The brake fluid level must be between the “Min” and “Max” ⇒fig. 187 mark-
ings.
The fluid level may drop slightly after a period of time due to the automatic
compensation for brake pad wear. This is quite normal.
H owe ve r, if th e le ve l goes d own not icea bly i n a short time, or drops below the
“Min” mark, there may be a leak in the brake system. If the fluid level in the
reservoir is too low, this will be indicated by the brake warning lamp
⇒ page 70 and ⇒page 77. If this should happen, take the car to a qualified
workshop immediately and have the brake system inspected.

Wheels and tyres
242Wheels and tyresWheelsGeneral notesAvoiding damage
– If you have to drive over a kerb or similar obstacle, drive very
slowly and as near as possible at a right angle to the kerb.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage (cuts, cracks or blisters, etc.). Remove any foreign objects embedded in the treads.
Storing tyres
– Mark tyres when you remove them to indicate the direction of rotation. This ensures you will be able to install them correctly
when you replace them.
– When removed, the wheels and/or tyres should be stored in a cool, dry and preferably dark location.
– Store tyres in a vertical position if they are not fitted on wheel rims.New tyres
New tyres have to be run-in.
The tread depth of new tyres may vary, according to the type and make of tyre
and the tread pattern. Concealed damage
Damage to tyres and rims is often not readily visible. If you notice unusual
vibrations or the car pulling to one side, this may indicate that one of the tyres
is damaged. The tyres should be checked immediately by an Authorised
Service Centre.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with
directional tread. Always observe the direction of rotation indicated when
fitting the wheel. This guarantees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
WARNING
•New tyres do not have maximum grip in the first 500 km. Drive particu-
larly carefully to avoid risk of accident.•Never drive with damaged tyres. This may cause an accident.•If you notice unusual vibration or if the vehicle pulls to one side when
driving, stop the vehicle immediately and check the tyres for damage.
Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the tank flap.1. Read the required tyre inflation pressure from the sticker. The values refer to Summer tyres. For Winter tyres, you must add 0.2
bar to the values given on the sticker.

2. The tyre pressures should only be checked when the tyres are
cold. The slightly raised pressures of warm tyres must not be
reduced.
3. Adjust the tyre pressure to the load you are carrying.Tyre pressure
The correct tyre pressure is especially important at high speeds. The pressure
should therefore be checked at least once a month and before starting a
journey.
The sticker with the tyre pressure values can be found on the inside of the
tank flap. The tyre pressure values given are for cold tyres. Do not reduce the
slightly raised pressures of warm tyres ⇒.
WARNING
•Check the tyre pressure at least once per month. Checking tyre pressure
value is very important. If the tyre pressure is too high or too low, there is
an increased danger of accidents - particularly at high speeds.•A tyre can easily burst if the pressure is too low, causing an accident!•At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.•If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!For the sake of the environment
Under-inflated tyres will increase fuel consumption.
Tyre pressure monitoring*
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 cluster display.
Note that tyre pressure also depends on tyre temperature. 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. For this reason, 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.

 is displayed and indicates that the tyre pressure for a least
one tyre is insufficient.
- Stop the vehicle.
- Switch the engine off.
- Check the tyre(s).
- Change the wheel if necessary.
Tyre pressure monitoring (RKA+)*
The type pressure monitor display on the instrument panel
indicates that 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 245 or after changing of swapping around wheels ⇒
page 180 - with the vehicle at a standstill and the engine running - press
⇒ fig. 188. 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 extremely 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

246Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ page 245, fig. 189 , 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 car'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 244.
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 change them around as shown ⇒page 245, fig. 190. 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.•I f t y r e s s h o w e x ce s s i v e w e a r, y o u s h o u l d h a v e t h e r u n n i n g g e a r ch e cke d
