32Airbag system
Warning lamp for airbag and seat belt tensioner 
This warning lamp monitors the airbag and seat belt ten-
sioner system.
The warning lamp monitors all airbags and seat belt tensioners in the vehi-
cle, including control units and wiring connections.
Monitoring of airbag and belt tensioner system
Both the airbag and belt tensioner systems operation is constantly moni-
tored electronically. Each time the ignition is switched on, the warning lamp
 lights for several seconds and the display in the instrument panel*
shows AIRBAG / TENSIONER .
The system must be checked when the warning lamp  :
● does not light up when the ignition is switched on,
● after the ignition is switched on, it turns off after 4 seconds,
● turns off and then lights up again after the ignition is switched on,
● lights up or flashes while the vehicle is moving.
In the event of a malfunction, the warning lamp remains on continuously. In
addition, depending on the malfunction, a fault message appears in the
display of the instrument panel for approx. 10 seconds and a short acoustic
signal is given. In this event, you should have a specialised workshop check
the system immediately.
If any of the airbags are de-activated by the Authorised Service Centre, the
indicator lights for several seconds more after the verification and will turn
off if there is no fault.WARNING
● If there is a malfunction, the airbag and belt tensioner system cannot
properly perform its protective function.
● If a malfunction occurred, have the system checked immediately by a
specialised workshop. Otherwise, in the event of an accident, the airbag
system and belt tensioners may not be triggered, or may not be triggered
correctly.

Repairs, maintenance and disposal of airbags
The parts of the airbag system are installed in various places in your vehi-
cle. If work is carried out on the airbag system or parts have to be removed
and fitted on the system when performing other repair work, parts of the air-
bag system may be damaged. In the event of an accident this could cause
the airbag to inflate incorrectly or not inflate at all.
The relevant safety requirements must be observed when the vehicle or
components of the airbag are scrapped. Specialised workshops and vehicle
disposal centres are familiar with these requirements.
WARNING
● If repairs are not carried out by a professional, or if the airbags are
used incorrectly, the risk of severe or fatal injuries is increased. The air-
bags may fail to inflate, or could inflate in the wrong circumstances.
● Do not cover or stick anything on the steering wheel hub or the sur-
face of the airbag unit on the passenger side of the dash panel, and do
not obstruct or modify them in any way.
● It is important not to attach any objects such as cup holders or tele-
phone mountings to the surfaces covering the airbag units. 

plicate the aid in case of emergency.
Note
● The remote control can be programmed by means of pressing the un-
locking button once; as a result, only the driver door will unlock. When the
button is pressed once more, all doors and the tailgate will be unlocked.
● The remote control functions only when you are in range ⇒ fig. 63 (red
area).
● If the vehicle is unlocked using the 

1 button, it will lock again auto-
matically if any of the doors or the tailgate are not opened within 30 sec-
onds after unlocking it. This function prevents the vehicle from remaining
unlocked if the unlock button is pressed by mistake.
● If the vehicle cannot be opened and closed using the remote control,
the remote control key will have to be re-synchronised ⇒ page 105.
Changing the battery
If the battery indicator does not flash when the buttons are pushed, the bat-
tery must be replaced.
CAUTION
The use of inappropriate batteries may damage the radio frequency remote
control. For this reason, always replace the dead battery with another of the
same size and power.
For the sake of the environment

Driving and the environment
Diesel engine particulate filter*
The diesel engine particulate filter eliminates soot produced
by burning diesel.
Fig. 136 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. 136.
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
indicator  for the diesel engine particulate filter indicator 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 83.
WARNING
● The diesel engine particulate filter may reach extremely high temper-
atures; the vehicle should be parked so that the exhaust pipe does not
come into contact with flammable materials underneath the vehicle. Oth-
erwise there is a risk of fire.
CAUTION
● Your vehicle is not designed to use biodiesel fuel. Never, under any cir-
cumstances refuel with biodiesel. The use of biodiesel fuel could damage
the engine and the fuel system. The addition of biodiesel to diesel by the
diesel producer in accordance with standard EN 590 is authorised and will
not cause damage to the engine or the fuel system.
● Using diesel fuel with a high sulphur content may significantly reduce
the working life of the diesel particulate filter. Your Authorised Service Cen-
tre will be able to tell you which countries have diesel with a high sulphur
content. 

Wheels and tyres
WARNING
● Never adjust tyre pressure when the tyres are hot. This may damage
or even burst the tyres. Risk of accident!
● An insufficiently inflated tyre flexes a lot more at high speeds and
causes significant heating of the tyre. Under these conditions, the tyre
bead may be released or the tyre may burst. Risk of accident!
For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear. 
Significant tyre pressure loss
The tyre symbol  is displayed and indicates that the tyre pressure
of at least one tyre is insufficient.
– Stop the vehicle.
– Switch the engine off.
– Check the tyre(s).
– Change the wheel if necessary. Tyre service life
The service life of tyres is dependent on tyre pressure, driv-
ing style and fitting.

Safety FirstOperating InstructionsPractical TipsTechnical Specifications

236Wheels and tyres
Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ fig. 152, running across the tread. Depending on the make, there will be
6 to 8 of them evenly spaced around the tyre. Markings on the tyre sidewall
(for instance the letters “TWI” or other symbols) indicate the positions of
the tread wear indicators. The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next to the tread wear indicators).
Worn tyres must be replaced. Different figures may apply in export countries
⇒ 
.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-
out. For this reason, the tyre pressure should be checked at least once per
month ⇒ page 233.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisa-
ble to change them around as shown ⇒ fig. 153. All the tyres will then last
for about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which re-
sults in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause exces-
sive wear on steering, suspension and tyres. A wheel must also be reba-
lanced when a new tyre is fitted. Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety
of the vehicle. If tyres show excessive wear, you should have the wheel
alignment checked by an Authorised Service Centre.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!
● The tyres must be replaced at the latest when the tread wear indica-
tors are worn ⇒ page 236. Failure to do so could result in an accident.
Worn tyres do not grip well at high speeds on wet roads. There is also a
greater risk of aquaplaning.
● At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
● If tyres show excessive wear, you should have the running gear
checked by an Authorised Service Centre.
● Keep chemicals such as oil, fuel and brake fluid away from tyres.
● Damaged wheels and tyres must be replaced immediately!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. 
