The engine compartment is a dangerous area! Before you open the 
bonnet to work on the engine or in the engine compartment, you must 
switch the engine off and allo w it to cool to reduce the risk of scalding or 
other kind of injuries. Read and  observe the relevant warnings 
⇒ page 213.Note
•
The appropriate warning lamp for a fault  will light up in vehicles without 
warning or information texts in the display.
•
In vehicles with warning or information texts on the screen, the appro-
priate warning lamp for a fault will ligh t up and a warning or information text 
will also appear on the screen.
Fuel level / reserve 
This symbol lights up to indicate that the fuel tank under the 
reserve level.It lights up when only 7 litres of fuel remain in the tank. Also, an  audible 
warning  is given. This serves as a reminder to fill up with fuel at the earliest 
opportunity  ⇒page 210.
The instrument panel displ ays the following message
8): PLEASE REFUEL! .
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, while 
three acoustic warning signals  ⇒  are emitted.
This means that either the coolant level is too low or the coolant temperature 
is too high.
Coolant temperature too high
The instrument panel disp lays the following message
9): CHECK COOLANT 
INSTRUCTIONS MANUAL  ⇒ page 220.
First look at the coolant temperature gauge. The coolant temperature is too 
high if the needle is over the warning area on the dial.  Stop the vehicle, 
switch the engine off and wait for it to cool down.  Check the coolant level.
If the coolant level is correct, the over heating may be caused by a malfunction 
of the radiator fan. Check the radiator fan fuse and have it replaced if neces-
sary  ⇒page 249.
If the warning lamp lights  up again after driving on for a short distance,  stop 
the vehicle and switch the engine off . Contact an Authorised Service Centre 
or a qualified workshop.

 is switched on once main beams are on or once the 
headlight flasher is operating.
Further information  ⇒page 116.
Soot accumulation in the diesel engine particulate filter 
If the indicator lights 
 you may help the filter clear itself by driving in the 
appropriate manner.
To do this, drive about 15 minutes in 4th or 5th gear (automatic gearbox: S 
gear range) at a speed of 60 km/h, with the engine running at approximately 
2000 rpm. In this way, the pollen buil d up in the filter is burned. When 
cleaning is successful, the indicator turns off.
If the indicator 
 is not deactivated, bring the vehicle to a specialised work-
shop to repair the fault.
WARNING
•
Always drive according to the road  weather conditions, the terrain and 
traffic. Driving recommendations should never lead to illegal manoeuvres 
in surrounding traffic.
•
The diesel engine particulate filter may reach extremely high tempera-
tures; it should not enter into contact with flammable materials under-
neath the vehicle. Failure to comply could result in fire.
Anti-lock brake system (ABS) 
 
A warning lamp system monitors the ABS.
The warning lamp 
 should light up for a few seconds when the ignition is 
switched on. It goes out again after th e system has run through an automatic 
test sequence.

 does not light up when the ignition is switched on.
•
The warning lamp does not go out again after a few seconds.
•
The warning lamp lights up when the vehicle is moving.
The vehicle can still be braked in the normal way (except that the ABS control 
function will not function). Please take the vehicle to a qualified workshop as 
soon as possible. For further information on the ABS see the  ⇒page 183.
If a fault occurs in the ABS, the ESP* warning lamp will also light up.
Brake system fault
If the ABS warning lamp 
 lights up together with the brake warning lamp 
, this indicates not only a fault in the  ABS function, but also a possible fault 
in the brake system  ⇒.

If the brake warning lamp 
 lights up together with the ABS warning 
lamp 
, the control function of the ABS could be out of action. This could 
cause the rear wheels to lock quickly when you brake. This could cause the 
rear to break away. Risk of skidding. Stop the vehicle and seek technical 
assistance.
Engine oil pressure 
This warning lamp indicates that the engine oil pressure is 
too low.If this warning symbol starts to flash, and is accompanied by three  audible 
warnings, switch off the engine and check the oil level. If the oil level is too 
low, add more engine oil  ⇒page 216.
The instrument panel displays the following message
15): STOP ENGINE OIL 
PRESSURE INSTRUCTIONS MANUAL .

Indicator for open doors or tailgate* 
This indicator lights if one of th e doors or the tailgate is open.The warning light 
 should go off when all the doors are closed correctly.
The system also works when the ignition is switched off. It should go off 
approx. 15 seconds after the vehicle is locked.
Power steering system* 
For vehicles with power steering, the level of steering assistance depends on 
the vehicle's speed and on the steering angle.
The warning lamp should li ght up for a few seconds when the ignition is 
switched on. It should go out once the engine is started.
If the battery is disconnected, the indicator remains lit, even with the engine 
running. The warning light only goes of f after a distance of approx. 50 m.
There is a fault in the electromechanical steering system if the lamp does not 
go out or lights up whilst the vehicle  is in motion. The indicator may appear 
in two different colours to indicate faults . If it lights yellow, this indicates a 
minor fault. If it lights red, seek workshop assistance immediately, if no 
assistance is available stop driving. Stop the vehicle and seek technical

Unlocking and locking
100Anti-theft alarm system*Description of anti-theft alarm system*
The anti-theft alarm triggers if unauthorised movements are 
detected around the vehicle.The anti-theft alarm makes it more diffi cult to break into the vehicle or steal 
it. Audible and visible alarms are triggered if the car is opened using the key, 
or if unauthorised access to the vehicle is forced.
The anti-theft alarm system is automatically connected on locking the 
vehicle. The system is then primed.
When does the system trigger an alarm?
The system triggers an alarm if the following unauthorised actions are carried 
out when the car is locked:•
Mechanical opening of the vehicle with the vehicle key
•
Opening a door
•
Opening the bonnet
•
Opening the tailgate
•
Switching on the ignition
•
Movements in the vehicle
•
Undue manipulation of the alarm
•
Battery handling
The acoustic signals sound and the indicators flash for approx. 30 seconds. 
This may be repeated up to 10 times depending on the country.
Opening the doors mechanically (emergency opening)
If the remote control function fails, you will have to use the key to unlock the 
car. This is done as follows:
•
Unfold the key by pressing the button shown by the (arrow).
•
Use the lock on the driver door to un lock the vehicle. The anti-theft alarm 
system remains active, but an alarm is not triggered immediately.
•
Switch on the ignition within 15 seconds. When the ignition is switched 
on, the electronic immobiliser recognises a valid vehicle key and deactivates 
the anti-theft alarm system. If you do not switch on the ignition within 15 
seconds, the alarm is triggered.
How to switch the alarm off
When the vehicle is unlocked via the unlocking button of the remote control 
or when the key is inserted in the ignition lock.Note
•
If, after the alarm goes off, access is gained to a second secured zone 
(e.g. the tailgate is  opened after a door has been opened), the warning signal 
is triggered again.
•
Vehicle monitoring remains active even if the battery is disconnected or 
not working for any reason.
•
The alarm is triggered immediately if one of the battery cables is discon-
nected while the alarm system is active.
Volumetric sensor*
Monitoring or control function  incorporated in the anti-theft 
alarm* which detects unauthorized vehicle entry by means of 
ultrasound.The system consists of 3 sensors, 2 emitters and a receptor.

WARNING
•
Worn and dirty wiper blades obstruct visibility and reduce safety levels.
•
In cold conditions, you should not use the wash / wipe system unless 
you have warmed the windscreen with  the heating and ventilation system. 
The washer fluid could otherwise freeze on the windscreen and obscure 
your view of the road.
•
Always note the corresponding warnings on  ⇒page 223, “Changing 
windscreen wiper blades”.Caution
In icy conditions, always check that the wiper blades are not frozen to the 
glass before using the wipers for the first time. If you switch on the wipers 
when the wiper blades are frozen to the windscreen, you could damage both 
the wiper blades and the wiper motor.
Note
•
The windscreen wipers will only work when the ignition is switched on.
•
In certain versions of vehicles with alarms, the windscreen wiper will only 
work when the ignition is  on and the bonnet closed.
•
When in use, the wipers do not go as far as the rest position. When the 
lever is moved to position 0, they are totally hidden.
•
The next speed down will automatically be selected if speed ⇒ page 121, 
fig. 85    or   is selected when the vehicle stops. The set speed will be 
resumed when the vehicle starts again
•
The windscreen will be wiped again after approximately five seconds once 
the “automatic wipe/wash system” has been operated, provided the vehicle 
is in transit (drip function). If you activate the wipers less than three secionds 
after the drip function, a new wash sequence will begin without the last wipe.  For the “drip” function to work again, you have to turn the ignition off and 
then on again.
•
When the “intermittent wipe function” is on, the intervals are directly 
proportional to the speed. This way, the higher the vehicle speed the shorter 
the intervals.
•
The wiper will try to wipe away any obstacles that are on the windscreen. 
The wiper will stop moving if the obstacle blocks its path. Remove the 
obstacle and switch the wiper back on again.
•
Before removing any objects that may be trapped in the side areas of the 
windscreen, always move the wiper arms to the service position (horizontal).
•
The heat output of the heated jets is controlled automatically when the 
ignition is switched on, depending upon the outside temperature.

If possible, use a de-icing spray to remove ice. If you use an ice scraper, push 
it in one direction only without swinging it.
Use window cleaner or a silicone remover to clean rubber, oil, grease and sili-
cone deposits off.
Wax deposits can be removed with a special cleaner available in your Author-
ised Service Centre. Wax deposits on the windscreen could cause the wiper 
blades to judder. If a window cleanser
, specifically for removing wax, is added 
to the windscreen washer fluid prevents wiper blades from juddering. Wax 
deposits are not removed.
Caution
•
Never use warm or hot water to remove snow and ice from windows and 
mirrors. This could cause the glass to crack!
•
The heating element for the rear window is located on the inner side of the 
window. To prevent damage, do not put stickers on the heating elements 
inside the window.
Cleaning windscreen wiper bladesClean wiper blades are essential to provide clear vision.
1.  Use a soft cloth to remove dust and dirt from the windscreen  wiper blades.
2.  Use window cleanser to clean the windscreen wiper blades. Use  a sponge or a cloth to remove stubborn stains.
Rubber seals maintenance
If rubber seals are well looked after, they will not freeze so 
quickly.1.  Use a soft cloth to remove dust and dirt from the rubber seals.
2.  Apply a specialist care product to the rubber seals.The strips on the doors,  windows, bonnet and rear lid will remain pliable and 
last longer if they are treated with a suitable care product (for example sili-
cone spray).
Caring for rubber seals will also prevent premature ageing and leaks. The 
doors will be easier to open. If rubber seals are well looked after, they will not 
freeze so quickly in winter.Door lock cylinders
The door lock cylinders can freeze up in winter.To de-ice the lock cylinders you should only use spray with lubricating and 
anti-corrosive properties.Cleaning chrome parts1.  Clean chrome parts with a damp cloth.
2.  Polish chrome parts with a soft, dry cloth.
