Driver information systemGeneral notes
The driver information system in the instrument panel shows
the status of various on-board systems at a glance.The display for the driver information system is in the centre of the instrument
panel.
The system runs a check on certain components and functions when the igni-
tion is switched on and while the vehi cle is moving. The DIS system gives an
audible warning if a fault should occur or if servicing is required, and a red or
yellow warning symbol (in some cases with a corresponding driver message)
appears in the dashboard display.
The driver is informed on the audio system.
The driver information system includes the following functions:
Note

72CD and radio displayIf the radio is switched on and no Priority 2 faults are indicated by the auto-
check control, the “OK” symbol will go out and the display will show the name
or frequency of the selected radio station and various other information,
depending on the type of radio fitted.
When in CD mode*, the display will show the current track.
These displays appear in addition to the display on the radio itself.
Ambient temperature displayThe ambient temperature is shown in the display when the ignition is
switched on ⇒fig. 49.
At temperatures below +5°C a snowflake symbol appears next to the temper-
ature display. This is to warn the driver to take extra care when there is a risk
of ice on the road. When the vehicle is stationary or travelling at very low
speeds, the temperature displayed may be slightly higher than the actual
ambient temperature as a result of heat coming from the engine.
If the vehicle has an air conditioning and the display is changed over to °F
(degrees Fahrenheit), the ambient temperature display automatically
changes over to °F ⇒ page 157.
WARNING
Do not rely on the ambient temperature display as an ice warning. Please
bear in mind that there may be ice on the roads even at ambient tempera-
tures of +5°C – beware of ice patches.

Note
When the display shows route guidance instructions from the navigation
system, the ambient temperature appears in the second line of the radio
display.Fuel range
The fuel range display can help you to plan your trip.The estimated fuel range is displayed in km. It shows how far the vehicle can
be driven with the amount of fuel left in the tank, assuming the same style of
driving. The fuel range is displayed in increments of 10 km.
The fuel range is calculated on the basis of the fuel consumption over the last
30 kilometres. The fuel range will increase if you drive in a more economical
manner.
Door catch/ tailgate warningThe door catch/tailgate warning symbol lights up if one or more of the doors,
or the bonnet or tailgate are not proper ly closed when the ignition is on. The
symbol also indicates which of these is not properly closed. The display in the
illustration ⇒fig. 50 shows that the front left door is open.
The corresponding part of the pictogram wil l flash if either the bonnet or tail-
gate are open. The warning symbol goes out when the bonnet, tailgate and
all the doors are closed.
On vehicles with a driver information system and an on-board computer* the
door catches/tailgate warning symbol can be switched off by briefly pressing
one of the control switches for the on-board computer ⇒page 85. However,
the warning symbol will appear again if any of the doors or the bonnet or tail-
gate is opened or closed.

Te c h n i c a l D a t a
The red symbols are used to indicate a Priority 1 fault (serious malfunction).
A red symbol is accompanied by
three warning chimes. The symbols will keep
flashing until the faults are corrected. If several Priority 1 faults are detected
at the same time, the symbols are displayed one after the other for about 2
seconds.
Fault in the brake system
A fault in the brake system should be rectified as soon as
possible.If the symbol
flashes in the display, there is a fault in the brake
system. One of the following messages will appear in the display
together with the symbol:
Stop vehicle, check brake fluid and hydraulic fluid levels
Warning! Fault in brake system (ABS) Please visit garage
– Stop the vehicle.
–Check the brake fluid level ⇒ page 222.
If the ABS fails, the ABS warning lamp
will light up together with the brake
system fault symbol
⇒ .
WARNING
•
Before opening the bonnet and checking the brake fluid level, observe
the warning information in ⇒page 213, “Work in the engine compart-
ment”.
•
If the brake fluid level in the reservoir is too low, this could result in an
accident. Do not drive on. Obtain technical assistance.
•
If the brake warning lamp lights up together with the ABS warning
lamp, this can mean that the control fun ction of the ABS is out of action. As
a result, the rear wheels can lock relatively easily when braking. Under
certain circumstances, the rear of the vehicle could suddenly sway from
side to side, with the subsequent danger of skidding. Drive carefully to the
nearest specialist garage and have the fault rectified.
Fault in the cooling system
Faults in the cooling system must be rectified immediately.If the
symbol flashes in the display, this means that either the
coolant temperature is too high or the coolant level is too low. The
following message will appear in the display together with the
symbol:
Switch off engine and check coolant level
–Stop the vehicle.
– Switch the engine off.
– Check the coolant level ⇒page 218.
– Add more coolant if necessary ⇒page 218.
– Wait for the symbol to go out before driving on.
– Obtain professional assistance if necessary.
If the coolant level is correct, the over heating may be caused by a malfunction
of the radiator fan.
WARNING (continued)

78If the alternator warning lamp lights up as well ⇒page 69, it is possible that
the drive belt has broken.
Caution
Do not drive on if the symbol
has come on to indicate a fault in the cooling
system, otherwise there is a risk of engine damage.
Engine oil pressure too low
If the engine oil pressure is too low the fault must be rectified
immediately.If the
symbol flashes in the display, the oil pressure is too low.
The following message will appear in the display together with the
symbol:
Switch off engine, check oil level
–Stop the vehicle.
– Switch the engine off.
– Check the engine oil level ⇒page 215.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒page 216.
Engine oil level correct
If the
symbol flashes and the engine oil level is correct, obtain profes-
sional assistance. Do not drive on. Do not continue to run the engine, even at
idle speed .
Note
The oil pressure warning lamp
is not an indicator for the oil level. The oil
level should therefore be checked regularl y, preferably every time you fill the
tank.
