Main beam headlights 
This control lamp lights up when the main beams are on.
The warning lamp  is switched on once main beams are on or once the
headlight flasher is operating.
For further information see ⇒ page 106. 
Electro-hydraulic steering* 
The level of steering assistance depends on the vehicle speed and on the
steering wheel turning speed.
The control lamp should light up for a few seconds when the ignition is
switched on. It should go out once the engine is started.
There is a fault in the electro-hydraulic steering system if the lamp does not
go out or lights up whilst the vehicle is in motion. Take the vehicle to the
Technical Service as soon as possible.
Note
When towing the vehicle with the engine stopped or due to a fault in the
power steering, this will not operate. The vehicle can still be steered, but it
will require greater force to turn the steering wheel. Emission control system* 
This warning lamp monitors the exhaust system.
Control lamp  flashes:
When there is misfiring that can damage the catalytic converter. Reduce
speed and drive carefully to the nearest specialised workshop to have the
engine checked.
Control lamp  is lit:
If a fault has developed during driving which has reduced the quality of the
exhaust gas (e.g. lambda probe fault). Reduce speed and drive carefully to
the nearest specialised workshop to have the engine checked. 
Coolant level*/temperature 
The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.
There is a fault if:
● The warning symbol does not go out again after a few seconds.
● The warning lamp lights up or flashes while the vehicle is moving, and
three acoustic warning signals ⇒ 
are emitted.
This means that either the coolant level is too low or the coolant tempera-
ture is too high.
Coolant temperature too high
If the warning light comes on, stop the vehicle, switch off the engine and
wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunc-
tion of the radiator fan. Check the radiator fan fuse and have it replaced if
necessary ⇒ page 231. 

Air conditioning
● The outside temperature is below +3°C.
● The air conditioning system compressor has been temporarily switched
off because of an increased engine coolant temperature.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air conditioning checked by a spe-
cialised workshop. 
Air recirculation 
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside.
When air recirculation mode is switched on (button ⇒ Fig. 103 
with
warning lamp) strong odours in the outside air do not enter the vehicle inte-
rior, for example when passing through a tunnel or in a traffic jam.
When the outside temperature is low, air recirculation mode improves heat-
ing performance by heating air from the interior instead of cold air from the
outside.
When the outside temperature is high, air recirculation mode improves cool-
ing performance by cooling air from the interior instead of warm air from
outside.
For safety reasons, the air recirculation should not be switched on when the
air distribution control is set to the windscreen setting .
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioner is switched off, the windows can quickly
mist over. Therefore, never leave the air recirculation mode switched on
for a long time (risk of accident).
Note
● When engaging reverse gear, the air recirculation is connected automat-
ically to prevent the entrance of exhaust gases in the vehicle on travelling
backwards. The control lamp on the button 
does not light up.
● If the temperature control is turned to the coldest setting (blue point)
and the switch AC
is activated, the “Air recirculation” function is automati-
cally activated in order to cool the vehicle rapidly using less energy; its
function control lamp will light.
● If the function is not deactivated by pressing the button, this will deacti-
vate after approx. 20 min. 
Economic use of the air conditioning
When the air conditioning is switched on, the compressor consumes engine
power and has influence on fuel consumption. Consider the following
points in order to have the system operating in the minimum possible time.
● If the vehicle interior has overheated due to an excessive solar radiation,
it is best to open the windows or doors to allow the hot air to escape.
● While in motion, the air conditioning should not be switched on if the
windows or the sunroof are open.* 

Driving
WARNING (Continued)
● Never accelerate when moving the selector lever or you may cause an
accident.
● Never move the selector lever to R or P when driving. Risk of accident!
● Before driving down a long, steep slope, it is advisable to reduce
speed and change into a lower gear.
● If you stop the vehicle up hill, always hold the foot brake strongly de-
pressed down to stop it from rolling back.
● Never allow the brake to rub and do not use the brake pedal too often
or for long periods. Constant braking will cause the brakes to overheat
and will considerably reduce the brake effect. This increases the braking
distance and could cause the brake system to fail.
● Never allow the vehicle to roll down a mountain or a slope with the
lever in the N or D position, regardless of whether the engine is running
or not.
CAUTION
● If you stop the vehicle up hills, do not attempt to stop it from rolling
back by depressing the accelerator when a gear has been selected. Other-
wise, the automatic gearbox may overheat causing damage. Pull the hand-
brake up or fully depress the brake pedal to prevent the vehicle from rolling
away.
● If you allow the vehicle to roll when the engine is not running, or with
the selector lever in position N, a lack of lubrication in the automatic gear-
box will damage it. Changing gear in tiptronic mode*

WARNING
If the vehicle moves with no control, an accident and serious injury may
occur.
● As a driver, you should never leave your vehicle if the engine is run-
ning and a gear is engaged. If you have to leave your vehicle while the
engine is running, you must always apply the handbrake and engage the
parking lock position P.
● If the engine is running and if D or R are engaged, you will need to
hold the vehicle stopped by depressing footbrake down. The vehicle
would creep forward as the power transmission is not fully interrupted
even when the engine is idling.
● Never accelerate when moving the selector lever or you may cause an
accident.
● Never move the selector lever to “R” or “P” when driving. Risk of acci-
dent.
● Before driving down a very steep slope, reduce your speed and shift
to first gear.
● Always hold the vehicle on the foot brake if you stop on hills. Other-
wise, the vehicle could roll back.
● Never allow the brake to rub and do not use the brake pedal too often
or for long periods. Constant braking will cause the brakes to overheat
and will considerably reduce the brake effect. This increases the braking
distance and could cause the brake system to fail.
WARNING
Never switch the engine off until the vehicle is stationary. You could lose
control of your vehicle. This could cause an accident and serious injury.
● The airbags and belt tensioners do not work when the ignition is
switched off.
WARNING (Continued)
● The brake servo does not work with the engine off. You need more
force to stop the vehicle.
● Power steering does not work when the engine is not running. That is
why it is much more difficult to turn the steering wheel.
● Never remove the key from the ignition if the vehicle is in motion. The
steering lock could suddenly engage, and you would not be able to steer
the vehicle.
● Never allow the vehicle to roll downhill with the selector lever in “N”,
regardless of whether the engine is running or not.
CAUTION
If you allow the vehicle to move when the engine is switched off or with the
selector lever in position “N”, take your foot off the accelerator and wait un-
til the engine starts idling before returning to position “D”. 
Kickdown feature
This feature allows maximum acceleration. If you press the accelerator down thoroughly, the gearbox automatically
changes down, depending on speed and engine speed, into a lower gear to
take full advantage of give the vehicle maximum acceleration.
The gearbox does not change gear until the engine reaches the maximum
determined engine speed for the gear. 

Intelligent technology
Electronic Stability Control (ESC)*
The ESC reduces the risk of skidding by braking the wheels individually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. When irregularities occur, for exam-
ple, if the vehicle begins to skid, the ESC brakes the appropriate wheel au-
tomatically.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle tends to oversteer, the system will act on the front
wheel on the outside of the turn.
WARNING
● Remember that not even the ESC can defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. The greater safety provided by the ESC should not
encourage you to run any risks.
CAUTION
● To ensure that the ESC works correctly, all four wheels must be fitted
with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
● Any modifications made to the vehicle (for example, to the engine,
brake system, running gear or to the combination of wheels and tyres) may
affect the operation of the ABS, EDL, ESC and ASR. Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during braking
⇒ page 169.

Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.
EDL helps the vehicle to start moving, accelerate and climb a gradient in
slippery conditions where this may otherwise be difficult or even impossi-
ble.
The system will control the revolutions of the driven wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 71.
At speeds of up to approximately 80 km/h (50 mph), it is able to balance
out differences in the speed of the driven wheels of approximately 100 rpm
caused by a slippery road surface on one side of the vehicle. It does this by
braking the wheel which has lost traction and distributing more driving
force to the other driven wheel via the differential.
To prevent the disc brake of the braking wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. The vehicle will con-
tinue to function normally without EDL. For this reason, the driver is not in-
formed that the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled
down. 

174Driving and the environment
recommend that you have the thickness of your brake pads checked by a
Technical Service more frequently than recommended in the Maintenance
Programme.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the vehicle, the effect of the brakes is
lessened as the brake discs are wet or even frozen (in winter). In this case
the brakes should be dried by pressing the brake pedal several times.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.
● New brake pads must be run in and do not have the correct friction
during the first 200 km (120 miles). However, the reduced braking ca-
pacity may be compensated by pressing on the brake pedal a little hard-
er. This also applies when the brake pads have to be changed further on.
● If brakes are wet or frozen, or if you are driving on roads which have
been salted, braking power may be lower than normal.
● On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed
and change down into a lower gear or range (depending on the type of
transmission). This makes use of engine braking and relieves the brakes.
● Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.
● Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.
● If the brake fluid loses its viscosity and is subjected to heavy use, va-
pour bubbles can form in the brake system. This reduces the efficiency of
the brakes.
WARNING (Continued)
● Non-standard or damaged front spoilers could restrict the airflow to
the brakes and cause them to overheat. Before purchasing accessories
please observe the relevant instructions ⇒ page 190, Technical modifi-
cations.
● If a brake system circuit fails, the braking distance will be increased
considerably. Contact a specialised workshop immediately and avoid un-
necessary journeys.

Exhaust gas purification system Catalytic converter*
To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages
the catalytic converter.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish with too much engine
oil ⇒ page 206, Topping up engine oil .
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 248.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest specialised workshop. In general, the exhaust gas warning lamp
will light up when any of the described symptoms occur ⇒ page 65. If this
happens, unburnt fuel can enter the exhaust system and escape into the en-
vironment. The catalytic converter can also be damaged by overheating. 

175
Driving and the environment
WARNING
The catalytic converter reaches very high temperatures! Risk of fire!
● Never park where the catalytic converter could come into contact with
dry grass or flammable materials under the vehicle.
● Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust sys-
tem. These materials could catch fire when the vehicle is being driven.
CAUTION
Never run the fuel tank completely dry because the irregularity of the fuel
supply may cause ignition problems. This allows unburnt fuel to enter the
exhaust system, which could cause overheating and damage the catalytic
converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel used. Quite often the problem can be
solved by changing to another brand of fuel. Diesel engine particulate filter*
The diesel engine particulate filter eliminates soot produced
by burning diesel.
Fig. 125 Vehicle data
sticker on back cover of
the Maintenance Pro-
gramme
Your vehicle is fitted with a DPF (Diesel particulate filter) if the vehicle data
sticker (back cover of the “Maintenance Programme”) lists the PR code 7GG
or 7MG ⇒ Fig. 125.
The diesel engine particulate filter eliminates most of the soot from the ex-
haust gas system. Under normal driving conditions, the filter cleans itself. If
the driving conditions do not allow the filter to clean itself (for example,
multiple short trips) the filter will be obstructed by dust and pollen and the
warning lamp  for the diesel engine particulate filter will light up. This
does not represent a fault, it is a warning that indicates that the filter has
not been able to regenerate automatically and that you must carry out a
cleaning cycle, as indicated in ⇒ page 70.
