WARNING
•
Failure to observe warning lamps and warning messages can result in 
serious personal injury or damage to your vehicle.
•
The risk of an accident increases if your vehicle breaks down. Use a 
warning triangle to draw the attention of other road users to your 
stationary vehicle so that it does not represent a danger.
•
The engine compartment of any motor vehicle is a area! Before you 
open the bonnet to work on the engin e or in the engine compartment, you 
must switch off the engine and allow it  to cool to reduce the risk of scalding 
or other injuries. Read and observe the relevant warnings  ⇒page 180.Note
•
The appropriate warning lamp for a fa ult will light up in vehicles without 
warning or information texts in the display.
•
In vehicles with warning or information texts in the display, the appro-
priate warning lamp for a fault will ligh t up and a warning or information text 
will also appear in the display.
Alternator 
 
This warning lamp signals a fault in the alternator.
The warning lamp 
 lights up when the ignition is switched on. It should go 
out when the engine has started running.
If the warning lamp  lights up while driving, the alternator is no longer 
charging the battery. You should immediately drive to the nearest qualified 
workshop.
You should avoid using electrical equipment that is not absolutely necessary 
because this will drain the battery.
If the indicator flashes the voltage is insufficient for normal vehicle 
operation.
Electro-hydraulic steering* 
The level of steering assistance depends on the vehicle 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 when the engine has started running.

64Coolant temperature too high
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 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 malfunction 
of the radiator fan. Check the radiator fan fuse and have it replaced if neces-
sary  ⇒page 213.
If the warning lamp lights up again  after driving on for a short distance,  stop 
the vehicle and switch off the engine. Contact an Authorised Service Centre 
or a qualified workshop.
Coolant level too low
First look at the coolant temperature gauge. If the needle is in the normal 
range, top up with coolant at the earliest opportunity  ⇒.
WARNING
•
If your vehicle is immobilised for any technical reasons, move it to a 
safe distance from traffic. Turn off the engine, turn on the hazard lights and 
place the warning triangle.
•
Never open the bonnet if you can see or hear steam or coolant escaping 
from the engine compartment. Risk of scalding. Wait until you can no 
longer see or hear escaping steam or coolant.
•
The engine compartment of any motor vehicle is a dangerous area! 
Before carrying out any work in the engine compartment, switch off the 
engine and allow it to cool down. Alwa ys note the corresponding warnings 
⇒ page 180.
Main beam headlights 
This warning lamp lights up when the main beams are on.The warning lamp 
 lights up when the main beams are on or when the 
headlight flasher is operated.
Further information  ⇒page 93.
Fuel level / reserve 
This symbol lights up to indicate that the fuel tank is down to 
the reserve level.This lights 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 177.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 the system has run through an automatic 
test sequence.
There is a fault in the ABS if:
•
The warning lamp 
 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.

Operating instructions
Tips and Maintenance
Te c h n i c a l  D a t a
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 148.
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  ⇒.
WARNING
•
Before opening the bonnet, read and observe the warnings on 
⇒ page 180, “Working in the engine compartment”.
•
If the brake warning lamp 
 should light up together with the ABS 
warning lamp 
, stop the vehicle immediately and check the brake fluid 
level in the reservoir  ⇒page 192, “Brake fluid”. If the fluid level has 
dropped below the “MIN” mark you must not drive on. Risk of accident. 
Obtain technical assistance.
•
If the brake fluid level is correct, the fault in the brake system may have 
been caused by a failure of the ABS system. 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.
Brake system* / handbrake 
 
The warning lamp lights up if the handbrake is applied, if the 
brake fluid level falls too low or if there is a fault in the brake 
system.
This warning lamp 
 lights up if
•
If the handbrake is on
•
If the brake fluid level is too low  ⇒page 192
•
If there is a fault in the brake system
This warning lamp can light up together with the anti-lock brake system 
warning lamp.
WARNING
•
If the brake warning lamp does not  go out, or if it lights up when 
driving, the brake fluid level  ⇒page 192, “Brake fluid” in the reservoir is 
too low. Risk of accident. Stop the vehicle and do not drive on. Obtain tech-
nical assistance.
•
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.
Emission control system* 
 
This warning lamp monitors the exhaust system.
Warning lamp 
 flashes:
When there is misfiring that can damage the catalytic converter. Reduce 
speed and drive carefully to the nearest qualified workshop to have the 
engine checked.
Warning 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 qualified workshop to have the engine checked.

Unlocking and locking
80
–Maximum time allowed for synchronising is 30 seconds.
– The normal key is used to activate the ignition, and the key with  the remote control is the key to be programmed.
– Check that the car is open before commencing programming.
– Place the key without remote control in the contact inside the  steering and ignition lock.
– Use the key with remote control and mechanically lock the  vehicle from the driver's door.
– Open and close the driver's door lock mechanically, using the  remote control key.
–  At the  same time press the button   on the remot
 e control 
key.
– Complete the procedure by removing the key from the contact.
It is possible that the vehicle could no  longer be opened and closed with the 
remote control if the button   is repeatedly pressed outside of the effective 
range of the radio frequency remote cont rol. The remote control key will have 
to be resynchronised.
Spare remote control keys are available from Authorised Service Centres, they 
must be matched to the locking system.
Anti-theft alarm system*Description of anti-theft alarm system*
The anti-theft alarm triggers an alarm if unauthorised move-
ments are detected around the vehicle.The anti-theft alarm makes it more difficult to break into the vehicle or steal 
it. Audible and visible alarms are triggered if the car is opened using the 
mechanical key, or if unauthorised  access is gained to the vehicle.
The anti-theft alarm system is automatically switched on when the vehicle is 
locked. For this, either turn the key once in the lock towards the locking posi-
tion or press button     on the radio-frequency remote control*. The 
system is activated immediately and the indicator light located on the 
driver’s door will flash along with the indicators indicating that the alarm and 
the locking security system (double lock) have been turned on.
When the vehicle is locked the indicator lamps light up only if the alarm has 
been correctly activated (all the protection zones should be correctly closed).
If any of the doors or the bonnet are open, when the alarm is connected these 
will not be included in the protection zones of the vehicle. If the door or 
bonnet is subsequently closed, they wi ll automatically be included in the 
vehicle protection zones and the indicators will flash accordingly.
When does the system trigger an alarm?
The alarm system is triggered, in the locked vehicle, when:•
a door
•
the bonnet or
•
the tailgate
are unduly opened
•
or the ignition is switched on

Tips and Maintenance
Te c h n i c a l  D a t a
Caution
•
Never attempt to remove dirt, mud or dust if the surface of the vehicle is 
dry. Never use a dry cloth or sponge for cleaning purposes. This could scratch 
the paintwork or glass on your vehicle.
•
Washing the vehicle in low temperatures: if the vehicle is rinsed with a 
hose, do not direct the water into the lock cylinders or the gaps around the 
doors, luggage compartment, or bonnet. Otherwise there is a risk of malfunc-
tion.For the sake of the environment
In the interests of environmental protection, the car should be washed only 
in specially provided wash bays. This prevents toxic, oil-laden waste water 
entering the sewerage system. In some districts, washing vehicles anywhere 
else may be prohibited.
Note
Do not wash the vehicle in direct sunlight.Washing the car with a high pressure cleaner
Be particularly careful when using a high pressure cleaner!– Always observe the instructions for the high-pressure cleaner,  particularly those concerning the  pressure and the spraying 
distance .
– Increase the spraying distance for soft materials and painted  bumpers. – Do not use a high pressure cleaner to remove ice or snow from 
windows  ⇒page 166.
– Never use concentrated jet nozzles or so-called “dirt blasters”  ⇒ .
– If possible, avoid sudden braking directly after washing the  vehicle. You must “dry” the brakes by applying the brakes care-
fully several times  ⇒page 152.
WARNING
•
Never wash tyres with a concentrated jet or cylindrical jet (“rotating 
nozzle”). Even at large spraying distances and short cleaning times, visible 
and invisible damage can occur to the tyres. This may cause an accident.
•
Moisture, ice and salt on the brakes  may affect braking efficiency. Risk 
of accident.Caution
•
Do not use water hotter than 60
°C. This could damage the car.
•
To avoid damage to the vehicle, maintain a sufficient distance from sensi-
tive materials for example: flexible hoses,  plastic, sound proofing, etc. This is 
especially important for bumpers painte d in the same colour as the vehicle. 
The closer the nozzle is to the surface, the greater the wear on the material.

Te c h n i c a l  D a t a
If possible use a de-icing spray to remove ice. If you use an ice scraper, push 
it in one direction only. Do not move it to and fro.
Use window cleaner or a silicone remover to clean off rubber, oil, grease and 
silicone deposits.
Wax deposits have to be removed with a special cleaner which is available 
from your Authorised Service Centre. Wax deposits on the windscreen could 
cause the wiper blades to judder. A window cleanser specifically for removing 
wax will stop the blades juddering if added to the windscreen washer fluid. 
Grease removing cleansers will not remove wax deposits.
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 over the heating elements on 
the inside of the window.
Cleaning windscreen wiper bladesClean wiper blades are essential for 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.
Care of rubber seals
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 weather 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 silicone 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.

Underbody sealant
The underside of the vehicle is coated to protect it from corro-
sion and damage.The protective coating could be damaged when driving. We recommend that 
the protective coating under the body and on the running gear should be 
checked, and reinstated if necessary, before and after the winter season.
We recommend that repair work and additional anti-corrosion work is carried 
out by your Authorised Service Centre.
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes, 
catalytic converter or the heat shields on the exhaust system. The heat of 
the exhaust system or the engine could cause them to ignite! This is a fire 
hazard.Cleaning the engine compartment
Take special care when cleaning the engine compartment.Anti-corrosion treatment
The engine compartment and the surface of the power unit are given anti-
corrosion treatment at the factory.
Good corrosion protection is particularly important in winter when the car is 
frequently driven on salted roads. To  prevent the salt corroding the vehicle, 
the entire engine compartment should  be thoroughly cleaned before and 
after the salting period.
Your Authorised Service Centre  is able to provide the correct cleaning and 
preserving products and has the necessary equipment. For this reason, we 
recommend having this work performed by them. The anti-corrosion protection is usually removed if the engine compartment 
is cleaned with grease remo
ving solutions, or if you have the engine cleaned. 
If this job is carried out, you should ensure that all surfaces, seams, joints and 
components in the engine compartmen t are given anti-corrosion treatment 
afterwards.
WARNING
•
When working in the engine compartm ent, always observe the safety 
warnings  ⇒page 180.
•
Switch off the engine, apply the parking brake firmly and always 
remove the key from the ignition before you open the bonnet.
•
Allow the engine to cool before you clean the engine compartment.
•
Do not clean the underside of vehicle, wheel arches without protecting 
your hands and arms. You may cut your self on sharp-edged metal parts. 
Failure to comply could result in injury.
•
Moisture, ice and salt on the brakes  may affect braking efficiency. Risk 
of accident. If possible, avoid sudden braking immediately after washing 
the vehicle.
•
Never touch the radiator fan. It is temperature-controlled and could 
start automatically, even when the key is removed from the ignition!For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed. 
The polluted water must be cleaned in an oil separator. For this reason, 
engine washing should be carried out only by a qualified workshop or a suit-
able filling station.
