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.
Overview
When you switch on the ignition, some of the
warning and indicator lamps light up briefly to

.... 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*.

WARNING
- Never run the engine in confined spaces.
The exhaust gases are toxic -risk of poison­
ing!
- Never switch off the engine until the vehicle
is stationary.
- The brake servo and the power steering sys­
tem work only when the engine is running.
You need more strength to steer and brake
the vehicle when the engine is switched off.
This would mean a greater risk of accidents
and serious injury, because you cannot steer
and brake in the normal manner.
Avoid high engine speeds, full throttle and ex­
treme load conditions until the engine has
reached its normal operating temperature;
otherwise this can damage the engine.
{:!)) Note
- When starting from cold the engine may be
a little noisy for the first few seconds until
oil pressure has built up in the hydraulic
tappets. This is quite normal and no cause
for concern.
- If you leave the vehicle with the ignition
switched on, it will be switched off auto­
matically after a while. Please note that
electrical equipment such as the exterior
lighting will also be switched off.

A WARNING
- Never switch off the engine until the vehicle
is stationary . Otherwise you may not have
the full benefit of the brake servo and power
steering. You may need more strength to
steer and brake the vehicle than you nor­
mally would. This would mean a greater risk
of accidents and serious injury, because you
cannot steer and brake in the normal man­
ner.
-Always take the key with you when you leave
the vehicle. Otherwise the engine can be
started or power-operated equipment such
as the electric windows can be used. This
could result in serious injury.
CD CAUTION
If the engine has been working hard for a long
time, there is a risk of heat building up in the
engine compartment after the engine has
been switched off; this could cause engine
damage. For this reason, you should leave the
engine idling for about 2 minutes before
switching it off.
(1'> Note
After the engine is stopped the radiator fan
may run on for up to 10 minutes, even if the
ignition is switched off. The fan may also start
running again after some time if the coolant
temperature rises due to a build-up of heat,

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

& WARNING
- When extending or retracting the rear spoil­
er, please make sure that no persons or ob­
jects are close to the moving spoiler -risk of
injury!
- If the indicator lamp (M appears, the rear
spoiler may have failed to extend due to a
malfunction. In this case, the car's handling
may be different at high speeds. Drive to a
qualified workshop without delay (but do
not exceed 140 km/h) and have the fault
rectified.
CD CAUTION
- If you need to push the vehicle, never put
your weight on the rear spoiler -Risk of
damage!
- To avoid damage to the rear spoiler, you
should not lean on it or apply any other type
of pressure.
- Do not operate the rear spoiler manually
when the boot lid is open or any moving
parts of the automatic rear spoiler are ob­
structed -risk of damage!
Note
Clean the rear spoiler housing every 2 to 3
months. The rear spoiler housing must be free
of ice, snow and leaves in order to operate
correctly.
106 Power
management
This system helps to ensure reliable
starting
The power management controls the distribu­
tion of electrical energy and thus helps to ensure
that
there
is always enough power available to
start the engine.
If a vehicle with a conventional electrical system
is left parked for a long time, the battery will
gradually lose its charge because certain electri­
cal equipment (such as the immobiliser) contin­
ues to draw current even when the ignition is off.
In some cases there may not be enough power
available to start the engine.
Your vehicle is equipped with an intelligent pow­
er management system to control the distribu­
tion of electrical energy. This significantly im­
proves reliability when starting the engine, and
also prolongs the life of the battery.
The main functions incorporated in the power
management system are battery diagnosis, re­
sidual current management and dynamic power
management.
Battery diagnosis
The battery diagnosis function constantly regis­
ters the condition of the battery. Sensors detect
the battery voltage, battery current and battery
temperature. This enables the system to calcu­
late the current power level and charge condition
of the battery.
Residual current management
The residual current management reduces power
consumption while the vehicle is parked. It con­
trols the supply of power to the various electrical
components while the ignition is switched off.
The system takes the battery diagnosis data into
consideration.
Depending on the power level of the battery, the
individual electrical components are switched off
one after the other to prevent the battery from
losing too much charge and to ensure that the
engine can be started reliably.
