Even if the coolant level is correct do not continue driving. You should obtain
technical assistance.WARNING
When working in the engine compartment, always bear in mind the safety
warnings ⇒ page 198.
Caution
Accessories in front of the air inlet reduce the cooling effect of the coolant. At
high outside temperatures and high engine loads, there is a risk of the
engine overheating.Rev counter
The rev. counter displays the engine speed in revolutions per
minute.The start of the red zone on the dial ⇒page 56, fig. 32 indicates the
maximum engine speed which may be used briefly when the engine is warm
and after it has been run in properly. However, it is advisable to change up a
gear or move the selector lever to D (or l ift your foot off the accelerator) before
the needle reaches the red zone.
Caution
The rev counter needle must never enter the red zone on the scale. Risk of
engine damage.

within 5 seconds of the initial memory value.
Ø mph - Average speed
The average speed will be shown after a distance of approximately 100
metres has been travelled. Dashes will appear in the display until that time.
The display will be updated every 5 seconds whilst the vehicle is in motion.
Miles - Distance travelled
The display shows the distance travelled since the ignition was switched on.
The maximum display value in both memories is 9999 miles. The memory will
automatically be deleted once this value has been reached.
 Miles - Fuel range
The fuel range is calculated using the fi gures for tank content and current fuel
consumption. It shows how far the vehicle can travel using the same condi-
tions as a reference.
Ø litre/100km - Average fuel consumption
The average fuel consumption will be shown ⇒page 62, fig. 41 after a
distance of approximately 100 metres has been travelled. Dashes will appear
in the display until that time. The display will be updated every 5 seconds
whilst the vehicle is in motion. The am ount of fuel used will not be shown. litres/100km or litres/hr - Current fuel consumption
The display will show the current fuel consumption in litre/km whilst the
vehicle is in motion or in litre/hour when
the vehicle is in a stationary position
with the engine running.
Using this display you can see how your driving style affects fuel consump-
tion ⇒page 180.
Ambient temperature display
The measurement margin extends from -45°C to +58°C. At temperatures
lower than +4°C, an “ice crystal symbol” is displayed and a “warning” sounds
if the vehicle is moving at more than 20 km/h (ice warning). This symbol will
flash for about 10 seconds and remains lit until the exterior temperature rises
above +4°C or 6°C if it was already lit.
WARNING
There could be black ice on the road surface even if the “snowflake symbol”
is not shown. You should, for this reason, not rely exclusively on this
display - Risk of accident!
Note
When the vehicle is stationary or travelling at very low speeds, the tempera-
ture displayed may be slightly higher than the actual ambient temperature as
a result of the heat radiated from the engine.Warning or information text in the display

COOLANT! INSTRUCTIONS MANUAL .
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 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 232.
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

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.
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 169.
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 198.
•
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 211, “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. Drive carefully to the nearest qualified workshop
and have the fault corrected.
Differential lock fault (EDL)*
EDL operates along with the ABS in vehicles equipped with an
Electronic Stabilisation Program (ESP)*A malfunction in the EDL is indicated by the ABS warning lamp

This warning lamp monitors th e engine management system
for petrol engines.
The warning lamp
 (Electronic Power Control) lights up when the ignition
is switched on to show that the lamp is working properly. It should go out
when the engine has started running.
If a fault develops in the electronic engine management system while you are
driving, this warning lamp will light up. Take the vehicle to an Authorised
Service Centre as soon as possible and have the engine checked.

The following text is displayed in the instrument panel display: EXHAUST
FUMES GO TO WORKSHOP! .
Electronic stabilisation programme (ESP)*

This warning lamp monitors the electronic stabilisation
program.
This program includes the ABS, EDL and TCS.
The warning lamp
 has the following functions:
•
It will light for about 2 seconds when the ignition is switched on while a
test of the function is carried out.
•
It flashes when the ESP is activated when driving.
•
It will light up continuously if there is a malfunction in the ESP.

Cockpit
82•
It will light up continuously if the ESP is switched off.
•
It will also come on if a fault should occur in the ABS because the ESP
operates in conjunction with the ABS.
If the ESP warning lamp
 lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESP.
In this case the ESP can be reactivated by switching the ignition off and then
on again. If the warning lamp goes out, this means the system is fully
functional.
Operating the foot brake

The footbrake must be depressed when this warning lamp lights up. This is
necessary when the automatic gearbox* selector lever is moved out of the
positions P or N.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 light up for a few seconds when the ignition is
switched on. It should go out when the engine has started running.
If the battery is disconnected, the indicator remains lit, even with the engine
running. The warning light only goes off after a distance of approx. 50 m.
There is a fault in the electromechanica l steering system if the lamp does not
go out or light up, wh ils
t 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 wo rkshop assistance immediately, if no
assistance is available stop driving. Stop the vehicle and seek technical
assistance. The power steering does not work if the battery is flat or if the engine is off (for example, for towing). You should take into account that you
will need considerably more power than normal to steer the vehicle if the
steering assistance is reduced
or has failed completely.
Brake pad wear indicator*

As the brake pad wear indicator only monitors the front brake pads, it is advis-
able to have the rear brake pads inspected at the same time.
The information text displayed in the instrument panel display is
16): CHECK
BRAKE PADS .
WARNING
Have the brake pads inspected immediately by a qualified dealership if the
warning display
 lights up.
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
about 15 seconds after the vehicle is locked.
