Instruments and warning lamps
Rev counter The red part of the rev counter scale
1›››
Fig. 24 ››› page 30 marks the area where
the engine control unit begins to limit the en-
gine speed. The engine control unit is re-
sponsible for reducing the revs to a safe lim-
it.
Before the needle reaches the red zone
change up into a higher gear, or move the se-
lector lever of the automatic gearbox to D.
In order to drive at an optimum RPM, follow
the gear change indications ››› page 32. For the sake of the environment
Changing to higher gears in advance helps to
reduce fuel consumption and noise levels,
helps to protect the environment and benefits
both the useful life and the reliability of the
engine. Speedometer
Speed warning
An audible warning will be heard when 120
km/h (75 mph) is exceeded. If the speed falls
below this limit, the audible warning
switches off. Note
This function is only valid for certain coun-
tries. Coolant temperature gauge
The coolant temperature gauge
4
››› Fig. 24
››› page 30 only works when the ignition is
sw it
ched on.
Damage to the engine can be avoided by ob-
serving the indications regarding the temper-
ature zones.
Engine cold
If the needle is still on the left of the scale,
the engine has not yet reached operating
temperature. Avoid high engine speeds, hard
acceleration and subjecting the engine to
high loads.
Operating temperature zone
When the needle has reached the central part
of the scale, this means the engine has
reached operating temperature. Running the
engine at full throttle and the high tempera-
tures involved can cause the needle to be
positioned in the zone on the right. CAUTION
The additional headlights and other parts
placed in front of the fresh air inlets reduce
the effect of engine cooling. With high out-
side temperatures and engine speeds a risk
becomes present of the engine overheating.

The fuel tank has a capacity of approx. 55 li-
tres. When the needle reaches the reserve
area, the ›››

warning symbol illu-
minates on the general instrument panel and
an audible warning can be heard. CAUTION
Never completely empty the tank! An irregu-
larity in the fuel supply system can cause ir-
regularities when the engine is running. Un-
burned fuel can reach the exhaust gas sys-
tem, which can cause deterioration of the cat-
alytic converter. Note
Some vehicles come fitted with the fuel
gauge on the general instrument panel. 31

Instruments and warning lamps
Go to a technical service.
Particulate filter (diesel engines)The particulate filter eliminates soot from
emissions. The particles accumulate in the
filter where they are normally burned off.
If the warning lamp
is illuminated, the fil-
ter is obstructed by soot.
In order for the filter to clean itself (if the traf-
fic conditions ››› so permit) it is essential
to drive for at least 15 minutes (or until the
warning lamp switches off) with 4th or 5th
gear engaged (automatic gearbox: position
S) at a minimum speed of 60 km/h (37 mph)
with the engine speed between
1,800-2,500 rpm.
The warning lamp switches off once the
filter has been successfully cleaned.
If the cleaning process is not successful, the
warning lamp does not switch off and the
warning lamp starts to flash.
The informative display indicates:
Diesel particulate filter. Instruction Manual!
The engine control unit allows driving to con-
tinue in an emergency program. When
switching the ignition off and on again, the
warning lamp also illuminates.
Go to a technical service. WARNING
● The particulate filter attains very high tem-
peratures. Therefore, do not park the vehicle
in places where the exhaust pipe could come
into contact with dry grass or with highly-
flammable materials. Risk of fire! CAUTION
While the warning lamp is lit up, the fuel
c
onsumption is high, and in certain condi-
tions, the engine power is reduced. Note
● In order for the particulate filter to burn off
soot in a correct manner, avoid carrying out
frequent short journeys.
● Using diesel fuel with a high sulphur count
can considerably reduce the useful life of the
particulate filter. The specialised service pro-
vides information about the countries where
fuel with a high sulphur content is used. Fuel reserve
The warning lamp illuminates when ap-
proximately only 7 litres of fuel remain in the
tank
The informative display indicates:
Refuel! Fuel range…km...(miles) Note
The message on the display switches off only
after refuelling and carrying out a short jour-
ney. Airbag system
If the warning lamp
is lit up, there is a
f au
lt in the airbag system.
The informative display indicates: Airbag fault!
The airbag system availability is controlled
electronically, regardless of whether an air-
bag is disabled.
If the front airbag, side airbag, head protec-
tion airbag or the belt tensioner are disabled
using the diagnostics system:
● After switching on the ignition, the warn-
ing lamp illuminates for about 4 seconds and
flashes for another 12 seconds.

Operation
If the front passenger airbag has been disa-
bled with the airbag switch located in the
storage compartment side:
● When the ignition is turned on, the
warning lamp illuminates for about 4 sec-
onds.
● The airbag is disabled, signalled with the
warning lamp
which lights up with the
word placed in the cen-
tre part of the dash panel ››› Fig. 18

When there is a fault in the airbag system,
have an inspection carried out by an Author-
ised Service. Otherwise the airbags may fail
to trigger in an accident. Tyre pressure monitoring system*
If the
warning lamp illuminates, the pres-
sure in one of the tyres has decreased signifi-
cantly. Check and adjust the pressure of all
the tyres ›››

If the
warning lamp flashes, there is a fault
in the system.

If the battery is disconnected the warning
lamp lights up when the ignition is switch-

If the
warning lamp illuminates, the level
of w
indscreen washer fluid in the tank is very
low. Fill the windscreen washer fluid

The informative display indicates: Refill windscreen washer fluid!
Turn signals Depending on the position of the turn signal
lever the left warning lamp on the left

to the brake pedal. Risk of accident!
● Press down on the clutch pedal when stop-
ping and braking with a manual gearbox, pet-
rol engine vehicle at low speed. Otherwise,
the brake servo might not work properly. Risk
of accident!
● In the event of damage to the standard
front spoiler or where a different front spoil-
er, wheel trims, etc. are subsequently fitted,
make sure the air vent to the brakes on the
front wheels is not blocked. Otherwise, brak-
ing operations may be impaired. Risk of acci-
dent!
● Always fully release the handbrake. If it is
only partially released, this will cause over-
heating of the rear brakes, which can impair
the function of the brake system. Risk of acci-
dent!
● Never leave children unsupervised in the
vehicle. They could release the handbrake or
move the gear lever. The vehicle could start
moving. Risk of accident! ●
Insufficient fuel can cause the engine to run
irregularly or to switch off. Brake assist sys-
tems could be impaired. Risk of accident!
● Always adjust your driving style to suit visi-
bility, the weather and road and traffic condi-
tions. The best vehicle safety offered by
brake assist systems must never encourage
you to run greater risks. Risk of accident! CAUTION
● Observe the information concerning new
brake pads ››› page 104
.
● Wher e br
aking is not necessary, do not
wear down the brake pads by pressing down
gently on the brake pedal. This causes the
brakes to overheat, increasing their wear and
increasing braking distances.
● To ensure the brake assist systems work
properly, all wheels must be fitted with tyres
approved by the manufacturer. Note
● If you brake suddenly and the brake system
control unit regards the situation as hazard-
ous for the drivers behind you, the brake
lights will begin to flash automatically. After
reducing speed to approximately 10 km/h (6
mph) or stopping the vehicle, the brake lights
will stop flashing and the hazard warning
lights will switch on. The hazard warning
lights are automatically switched off when
you accelerate or restart the vehicle. 98
