- 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-

Turn the knob to the desired position:
Q/ P -In this position , you can adjust the
driver's and front passenger's exterior mirrors
by turning the knob in the desired direction.
(ijjl -The mirrors are heated depending on the
outside temperature.

Passenger exterior mirror tilt function*
(only with memory for exterior mirrows)
To help you see the curb when backing into a
parking space, the surface of the mirror tilts
slightly . The knob must be in the
P position
for this to happen .
You can adjust the tilted mirror surface by
turning the knob in the desired direction .
When you move out of reverse and into anoth ­
er gear, the new mirror position is stored and
assigned to the key you are using.
The mirror goes back into its original position
once you d rive forward faster than 9 mph
(15 km/h) or switch the ignition off .
,&. WARNING
Curved mirror surfaces (convex or spheri­
cal*) increase your field of view. Remem­
ber that vehicles or other objects will ap­
pear smaller and farther away than when
seen in a flat mirror. If you use this mirror
to estimate distances of following vehicles
when changing lanes, you could estimate incorrectly and cause an accident.
(D Note
- If the mirror housing is moved uninten­
tionally (for example, while parking your
vehicle), then you must first fold the mir­ ror electrically. Do not readjust the mir­
ror housing manually. You could damage
the motor which controls the mirror .
-If you wash the vehicle in an automatic
car wash, you must fold the exterior mir­
rors in to reduce the risk of damage to
