The illumination for the instrument cluster lights up whenever you
switch on the ignition with the vehicle headlights off. As the
daylight fades, the instrument cluster illumination likewise dims
automatically and will go out complete ly when the outside light is
very low . Th is feature is meant to remind you to switch on the head­
lights when outside light conditions become poor. •
Engine coolant temperature gauge
The engine coolant gauge~ fig. 2 CD only works when the ignition
is on. To prevent damage to your engine, please note the following
important points:
Engine cold
As long as the needle remains at the left end of the gauge, the
engine still has not reached its operating temperature. Avoid high
engine speeds, heavy engine loads and heavy throttle applications.
Normal temperature
When the engine has reached its operating temperature, the needle
will move into the midd le of the gauge and remain there. If the
engine is working hard at high outside temperatures, the needle
may go furthe r to the right. This is no need to worry as long as the
J_ warning light in the instrument cluster does not illuminate.
Warning light in the instrument cluster -L
When the-•-warning light starts to flash, this can mean one of two
things: either the coo lant temperature is too high , or the coolant
level is too low~ page 31 . .,_

Instruments and warning /indicator lights
[ i J Tips
• The digital clock and the odometer are turned on for about 30
seconds when the driver's door is opened.

You can switch the display from miles to kilometers and vice versa
via the MMI.
Lower odometer
The lower odometer shows the total number of miles (kilometers)
driven. Upper
odometer (trip odometer )
The upper odometer shows the total number of mil·es (kilometers)
driven since you last reset the odometer to zero. You can use this
odometer when you wan t to keep track of how many miles (kilome ­
ters) you have driven for a single trip or errand. The last d igit indi­
cates 1/10 of a mile (100 meters) .
You can reset the trip odometer to zero by pressing the Reset button

vehic le was jump started or the batte ry is very weak, the ESP sensor
system goes through a learning process for the first few yards. The
warning/indicator light illuminates . The warning/indicator light
goes out as soon as the learning process is complete.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine, this may mean that the control system has
temporarily switched off the ESP . If this is case, you can reactivate
the ESP by turning the ignition off and then on again . The .,_

warning/indicator light should go out to show that the system is
fully functional again. For more information about the ESP~
