Fuel gauge
The gauge @ only works when the ignition is
switched on. If there is less than 7 litres of fuel in
the tank, the LED at the bottom of the dial will
light up in red and the indicator lamp tD will ap
pear c:::>page 16. The LED at the bottom of the
dial will flash in red if the fuel level is very low.
The tank capacity of your vehicle is given in the
Technical data section c:::> page 258.
CD CAUTION
Never run the tank completely dry. If there is
an irregular fuel supply, misfiring can occur.
Unburnt fuel can then enter the exhaust sys
tem. This can lead to overheating and dam
age to the catalytic converter.
Warning and indicator
lamps
Description
The warning and indicator lamps light up or flash
in the instrument cluster. Their purpose is to in
dicate functions or faults.
Some of the warning and indicator lamps may be
accompanied by a driver message and a warning
tone. The warning/indicator lamps and driver
messages on the display can be masked by fur
ther displays. To display a warning or message
again, use the controls on the multi-function
steering wheel to select the display tab for warn
ing/indicator lamps and messages c:::> page 18.
If several malfunctions have occurred, you can
use the thumbwheel to scroll through them on
the display.
Some of the warning lamps may be displayed in
different colours.

.... Avoid
driving at high speed
Avoid travelling at top speed. Fuel consumption,
exhaust emissions and noise Levels all increase
very rapidly at higher speeds. Driving at moder
ate speeds will help to save fuel.
Do not let the engine idle for longer than
necessary
Engine idling periods are automatically reduced
on vehicles with start/stop system*. On vehicles
without start/stop system*, it is worthwhile
switching off the engine at Level crossings, for in
stance, or at traffic lights with a Long red phase.
The fuel saved after only 30 -40 seconds is great
er 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.
Regular ser vicing
Regular servicing can establish a basis for good
fuel economy before you start driving. A well
serviced engine gives you the benefit of im
proved fuel efficiency as well as maximum relia
bility and an enhanced resale value.
A poorly maintained engine can consume up to
ten percent more fuel than necessary.
Check the oil level when filling the tank. Oil con
su mption depends to a great extent on the en
gine load and engine speed. It is quite normal
that the oil consumption of a new engine only
reaches its lowest level after a certain mileage.
This means that the oil consumption can only be
properly assessed after about 5,000 km. Depend
ing on your personal driving style, oil consump
tion can be up to 0.5 Ltr./1,000 km.
Avoid short trips
The engine and emission control system need to
reach their proper working temperature in order
to minimise fuel consumption and emissions . Driving
A cold engine uses disproportionately more fuel.
The engine only reaches its working temperature
after about four kilometres, when fuel consump
tion will return to a normal level.
Check tyre pressures
Always make sure the tyres are inflated to the
correct tyre pressures to save fuel. If the tyre
pressures are just 0.5 bar too Low, this can in
crease the fuel consumption by as much as 5 %.
Due to the greater rolling resistance, under-infla
tion also increases tyre wear and impairs han
dling.
The tyre pressures should always be checked
when the tyres are cold.
Do not use winter tyres all through the year; they
will increase fuel consumption by up to 10 %.
Avoid carrying unnecessary loads
Every kilo of extra weight will increase the fuel
consumption, so it is worth checking the Luggage
compartment occasionally to make sure that no
unnecessary Loads are being transported.
Save electrical energy
The engine drives the alternator to generate elec
tricity. This means that fuel consumption rises
when more power is required for electrical equip
ment. Switch off electrical equipment when it is
not needed. Electrical equipment which uses a
Lot of electricity includes the blower (at a high
setting), the rear window heating and the seat
heating*.

technology
The effectiveness of the brakes can also be tem
porarily reduced if the car is driven for some dis
tance without using the brakes when there is a
lot of salt on the road in winter. The layer of salt
that accumulates on the discs and pads can be re
moved with a few cautious brake applications.
Corrosion
There may be a tendency for dirt to build up on
the brake pads and corrosion to form on the discs
if the car is used infrequently, or if you only drive
low mileages without using the brakes very
much.
If the brakes are not used frequently, or if corro
sion has formed on the discs, it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed ¢.&,..
Faults in the brake system
If the brake pedal travel should ever increase
suddenly, this may mean that one of the two
brake circuits has failed. Drive immediately to the
nearest qualified workshop and have the fault
rectified. On the way to the dealer, be prepared
to use more pressure on the brake pedal and al
low for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid level is
monitored electronically.
Brake servo
The brake servo amplifies the pressure you apply
to the brake pedal. It only works when the engine
is running.
& WARNING
- When applying the brakes to clean off de
posits on the pads and discs, select a clear,
dry road. Be sure not to inconvenience or en
danger other road users; do not risk an acci
dent.
- Never let the car coast with the engine
switched off (this can cause accidents).
102 CD
CAUTION
- Never let the brakes "drag" by leaving your
foot on the pedal when you do not really in
tend to brake. This overheats the brakes, re
sulting in longer stopping distances and
greater wear.
- Before driving down a long, steep gradient,
it is advisable to reduce speed and move the
selector lever to a lower gear. In this way
you will make use of the engine braking ef
fect and relieve the load on the brakes. If
you still have to use the brakes, it is better
to brake firmly at intervals than to apply the
brakes continuously.
Note
- If the brake servo is out of action, you must
apply considerably more pressure to the
brake pedal than you normally would.
- If you wish to equip the car with accessories
such as a front spoiler or wheel covers, it is
important that the flow of air to the front
wheels is not obstructed, otherwise the
brakes can overheat.
Electronic stabilisation
control (ESC)
Description
The electronic stabilisation control (ES() increa
ses the car's stability. It reduces the tendency to
skid and improves the stability and road holding
of the vehicle. The ESC detects critical handling
situations, such as understeer, oversteer and
wheelspin on the driven wheels. It stabilises the
vehicle by braking individual wheels or by reduc
ing the engine torque. The indicator lamp Ii] in
the instrument cluster starts flashing as soon as
the ESC intervenes.
The following systems are integrated in the ESC:
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under
braking until the vehicle has reached a virtual
standstill. You can continue to steer the vehicle
even when the brakes are on full. Keep your foot
