Average fuel consumption
The average fuel consumption since the memory was last erased is shown in the
display in litres/100 km
⇒ page 14. This information can help you to adapt your
style of driving to the fuel consumption you wish to achieve.
If you wish to determine the average fuel consumption over a certain period of
time, you must erase the memory at the start of the new measurement using the
button B on the windshield wiper lever
⇒ fig. 6. A zero appears in the display for
the first approx. 300 m you drive after erasing the memory.
The indicated value will be updated every 5 seconds while you are driving. Note
The amount of fuel consumed will not be indicated.
Range The estimated range in kilometres is shown on the display. It indicates the dis-
tance you can still drive with your vehicle based on the present level of fuel in the
tank for the same style of driving.
The readout is shown in steps of 10 km. After lighting up of the indicator light for
the fuel reserve the display is shown in steps of 5 km.
The fuel consumption for the last 50 km is taken as a basis for calculating the
range. If you drive in a more economical manner from this moment on, the range
will be increased accordingly.
If the memory is set to zero (after disconnecting the battery), the fuel consump-
tion of 10 ltr./100 km is calculated for the range; afterwards the value is adapted
accordingly to the style of driving.
Distance driven The distance driven since the memory was last erased appears in the display
⇒ page 14. If you wish to calculate the distance driven as of a particular time, you
must erase the memory at this moment in time by pressing the button
B on the
windshield wiper lever ⇒ fig. 6 .
The maximum distance indicated in both memories is 1
999 km or on vehicles with
information display, it is 9 999 km. The indicator is set back to null if this period is
exceeded. Average speed The average speed since the memory was last erased is shown in the display in
km/hour
⇒ page 14. If you wish to determine the average speed over a certain pe-
riod of time, you must erase the memory at the start of the new measurement by
pressing the button B on the windshield wiper lever
⇒ fig. 6.
A zero appears in the display for the first 100 m you drive after erasing the memo-
ry.

ditions prevailing to top up with coolant. Keep the engine switched off
and obtain
professional assistance from a specialist garage, otherwise it could lead to severe
engine damage.
If the coolant is within the specified range, the increased temperature may be
caused by an operating problem at the coolant fan. Check the fuse of the coolant
fan, replace it if necessary ⇒ page 186, Fuse assignment at the battery (automatic
gearbox).
If the warning light does not go out although the coolant is at the correct level
and also the fuse of the fan is in proper order, do not continue driving. Contact a

Instruments and warning lights
Faults in the brake surface
If you notice that the braking distance has suddenly become longer and that the
brake pedal can be depressed further, it is possible that a brake circuit of the dual-
circuit brake system has failed. Drive, in such cases, to the nearest specialist ga-
rage without delay in order to have the problem rectified. Drive at a reduced
speed while on your way to the dealer and adapt your style of driving to the high-
er brake pedal pressure required.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The
level of the brake fluid is monitored electronically
⇒ page 26, Brake system .WARNING
● Only apply the brakes for the purpose of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users in
jeopardy.
● When retrospectively mounting a front spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced oth-
erwise the braking system could run too hot.
● Allow for the fact that new brake pads do not achieve their full braking ef-
ficiency until approximately 200 kilometres. New brake pads must be first
“run in ”
before they develop their optimal friction force. You can, however,
compensate for this slightly reduced braking force by increasing the pressure
on the brake pedal. This guideline also applies to any new brake pads installed
at a future date. CAUTION
● Never allow the brakes to rub by applying slight pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a lon-
ger braking distance and excessive wear.
● Before negotiating a steep downhill section, please reduce your speed, shift
down into the next lower gear (manual gearbox) or select a lower driving stage
(automatic gearbox). This enables you to make full use of the braking power of
the vehicle and reduces the strain on the brakes. Any additional braking should be
done intermittently, not continuously. Note
The brake light flashes automatically in case of an emergency braking at speeds
greater than 60 km/h or with the intervention of the ABS, which lasts longer than
1.5 seconds. After the speed was reduced below 10 km/h or the vehicle was stop-
ped, the brake light stops flashing and the hazard warning light system switches
on. The hazard warning light system is switched off automatically after accelerat-
ing or driving off again.
Brake booster The brake booster boosts the pressure which you generate with the brake pedal.
The necessary pressure is only generated when the engine is running.
WARNING
● Never switch off the engine before the vehicle is stationary.
● The brake booster only operates when the engine is running. Greater
physical effort for braking is required when engine is switched off. Because if
you do not stop as normal, this can cause an accident and severe injuries.
● While stopping or braking with a vehicle with a petrol engine and manual
transmission in the low rev range, press down on the clutch pedal. If you fail
to do so, the result may be an impairment of the function of the power brake.
You will apply a greater force to the brake pedal which you are usde to - dan-
ger of accident!
Antilock brake system (ABS) ABS prevents the wheels locking when braking.
General
The ABS contributes significantly to enhancing the active safety of your vehicle.
Compared to a car not fitted with the ABS brake system, you are able to retain op-
timal steering ability even during a full brake application on a slippery road surface
because the wheels do not lock up.
You must not expect, however, that the braking distance will be shorter under all
circumstances as a result of the ABS. The braking distance for example on gravel
and fresh snow, when you should anyway be driving slowly and cautiously, will be
longer. £ 131
Intelligent Technology Using the system Safety Driving Tips General Maintenance Breakdown assistance Technical data
Regular servicing
A poorly tuned engine uses an unnecessarily high amount of fuel.
Having your vehicle serviced regularly at a specialist garge enables you to satisfy
one of the requirements for economical motoring even before you set off on your
journey. Keeping your vehicle properly serviced not only has a positive effect on
the safety of your vehicle and maintaining its value, but also saves on fuel.
A poorly tuned engine can result in a fuel consumption which is 10% higher than
normal.
The foreseen maintenance work should be undertaken exactly according to the
Service schedule by a specialist garage.
Also check the oil level after refueling. Oil consumption is dependent to a consid-
erable extent on the load and speed of the engine. Oil consumption could be as
high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine has a higher oil consumption at first, and rea-
ches its lowest level only after a certain running in time. It is therefore not possi-
ble to correctly assess the oil consumption of a new vehicle until after you have
driven about 5 000 km. For the sake of the environment
● You can achieve additional improvements in your fuel economy by using high-
lubricity oils.
● Check the ground below your car at regular intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garge if you find any
stains caused by oil or other fluids on the floor. Avoid driving short distances Short distances result in an above-average high fuel consumption.
Fig. 123 Fuel consumption in litres/100
km at different temperatures
– Avoid driving a distance of no more than 4 km if the engine is cold.
The engine and catalytic converter must first have reached their optimal operat-
ing temperature in order to effectively reduce fuel consumption and pollutant
emissions.
The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel immediate-
ly after starting. Fuel consumption drops to 10 litres/100 km after just 1 kilometre.
The engine reaches its operating temperature (outside temperature and engine
dependent) only after about 4 to 10 kilometres and the fuel consumption then
stabilizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature. The
⇒ fig. 123 shows the different fuel consumptions for the same distance, on the
one hand at +20°C and on the other hand at -10°C. Your vehicle has a higher fuel
consumption in winter than in summer.
Checking tyre inflation pressures Tyres which are correctly inflated save fuel.
Always ensure that your tyres are inflated to the correct pressure at all times. The
rolling resistance will be increased if the tyre filling pressure is too low. This will
not only increase fuel consumption but also tyre wear and the driving behaviour
will worsen.
Always check the inflation pressure of the tyres when cold. £138
