- When switching the ignition on, the nee­
dles in the instrument cluster swing up­
ward briefly.
- The illumination for the instrument clus­
ter lights up whenever you switch on the
i gnition with the
vehicle headlights off .
As the daylight fades, the instrument
cluster illumination likewise dims auto­
matically a nd will go out completely
when the outside light is
very low. This
feature is meant to remind you to switch
on the headlights when outside light
conditions become poor .
Engine coolant temperature gauge
The engine coolant gauge q page 10, fig. 3 CD
only works when the ignition is on. To prevent
damage to your engine, please note the fol ­
lowing important points:
Engine cold
If the needle is at or close to the bottom of
the gauge, the engine has not yet reached its
operating temperature. Avoid high engine
speeds, heavy engine loads, and heavy throt ­
tle app lications.
Normal temperature
When the engine has reached its operating
temperature, the needle will
move to the mid­
dle of the gauge and remain there . If the en­
gine is working hard at high outs ide tempera­
tures, the needle may
move higher on the
gauge. This is not a cause for concern as long
as the . warning light in the instrument
cluster display does not illuminate. If the.
warning light in the instrument cluster dis­
play flashes, this can mean one of two things:
either the coolant
temperature is too high, or
the coolant
level is too low q page 18 Ill-

curves in the road depending on the vehicle
speed and the steering angle. This provides
b etter lighting through the curve . The system
operates at speeds between app roximately
6 mph (10 km/h) and 68 mph (110 km/h).
Static cornering light* (vehicles with adaptive
light) - the cornering light switches on at
speeds up to approximately 25 mph (40 km/

reached or when a turn signal is activated. The
area to the side of the vehicle is illuminated
better when turning .
The adaptive light and the co rnering light only
function when the switch is in the AU TO posi­
tion (automatic headlights*) .

- Daytime running lights and automatic
headlights* are only intended to assist
the driver . They do not relieve the driver
of his responsibility to check the head­
lights and to turn them on manually ac­
cording to the current light and visibility
conditions. For example, fog cannot be
detected by the light sensors*. So always
switch on the headlights
io under these
weather conditions and when driving in
the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists. Always turn on
the headlights so that you can see ahead
and so that others can see your car from
the back.

200 Cleaning and protec tio n
Automatic car wash
The vehicle can be washed in almost any
modern automatic car wash .
The vehicle paint is so durable that the vehicle
can normally be washed without problems in
an automatic car wash. However, the effect on
the paint depends to a large extent on the de­
sign of the facility, the filtering of the wash
water, the type of wash and care mater ial , etc.
I f the pa int has a dull appearance afte r going
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately.
If necessary, use a different car wash.
Before going through a car wash, be sure to
take the usual precautions such as closing the
windows and the roof . Factory installed an­
tennas must not be removed.
I f you have installed additional accessor ies on
the vehicle - such as spoilers, roof rack, etc. -
it is best to ask the car wash operator if these
should be removed .
