- When switching the ignition on, the nee­
dles in the instrument cluster move 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 head lights when outside light
conditions become poor .
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes) .

If engine RPM drops below 1,500, you should
downshift to the next lower gear. The red area
at the end of the scale indicates maximum
permissible engine RPM after the br eak-in pe­
riod. Before reaching this area, move these­
lector lever to position "D (Drive)" or ease
your foot off the acce lerator pedal.
(D Note
The tachometer needle should only briefly
be in the red zone: you could damage your
engine! The beg inning of the red zone var­
i es depending on the engine.
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

® Defective light bulb warning
The defective light bulb warning tells you
when a vehicle light bulb has become defec­
tive.
If a defect ive bulb has been detected by the
system or a light bu lb burns out, the
fsl sym­
bol with a message appears in the disp lay to
tell you wh ich bu lb is burnt out and where it is
l ocated. For example:

A WARNING
- Never use dayt ime running lights to see
where you are going. They are not bright
enough and w ill not let you see far
enough ahead for safety, especially at
dusk or when it is dark . Always switch on
the low beams at dusk or when it is dark.
- Automatic headlights are only intended
to assist the dr ive r. T hey do not relieve
the driver of his responsibility to check
the headlights and to tu rn them on man­
ually acco rding to the c urrent light and
visibili ty cond itions. For example, fog
and rain cannot be detected by the light
sensors . So a lways switch on the head­
lights under these weather cond itions
and when driving in the dark
io .
-Crashes can happen when yo u cannot see
the road ahead and when you cannot be
seen by other motorists .
- Always tur n on t he headlights so that
you can see ahead and so that o thers
c a n see yo ur ca r from the ba ck.
- Please obse rve lega l regu lations whe n
us ing the light ing systems descr ibed .
(D Tips
-The light sensor for headlight control is
l ocated in the rear v iew m irror mount .
Do not apply a ny stic kers to the w ind-
Clear vis ion 43
shield in th is area to p revent malfunc ­
tions or fai lures.
- Some exter io r light ing funct ions can be
adjusted in the d river informat ion sys­
tem
~ page 24.
- If you remove the ignition from the igni ­
tion lock while the headlights are still
on, a buzzer w ill sound as long as the
dr iver's door is open to rem ind you to
t u rn off the lights.
- Always observe the specific loca l regula ­
tions for your area as to when to use your
lights.
- With automatic headlights, the high­
beam function is also available, but w it h
one restrict ion:
If you have not sw itched
t he high beams back to low beams dur­
ing automatic headlight operation (fo r
example, afte r d riving throug h a tunnel),
only the low be ams come on the next
t ime au tomatic headlights are switched
on. To use the high beams, you firs t have
to pull the high beam lever back and
then push the leve r forward again.
- In coo l or damp weather, the inside of
the headlights, turn signals and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They w ill clear shortly after
sw itching them on. This does not affect
the se rv ice life of t he lig hti ng .

(D Note
The instrument cluster and center console
illumination (gauges and needles) comes
on when you switch on the ignition and the
vehicle headlights are off. Be aware of the
following difference between models built
to US or Canadian specifications :
- USA models: illumination of the instru­
ment cluster (gauges and needles), dash
and center console around the gearshift
lever is controlled by a light sensor locat­
ed in the instrument panel. The instru­
ment panel illumination will automati­
cally become dimmer as the daylight
fades away and eventually will go out
completely when outside light is very low.
This is to remind you, the driver, to
switch on the headlights before it gets
too dark.
- Canada models: instrument panel illumi­
nation will stay brig ht regardless of the
intensity of ambient light. Always be
aware of changes in outside light condi­
tions while you are driving. Respond in
time to fading daylight by turning the
light switch to position fD (or "AUTO" if
your car is equipped with this feature) to
turn on your headlights.
Luggage compartment light

come back a while later and drive off, the rain
sensor will reactivate itself after the vehicle
speed has exceeded 4 mph (6 km/h).
The rain sensor* is only activated with the
wiper lever set to position(!). When it starts
to rain, the rain sensor will automatically acti­
vate the intermittent wiping mode.
To reduce the sensitivity of the sensor, move
switch @ down. To increase the sensitivity,
move the switch up. The higher you adjust the
sensitivity, the faster the sensor will react
when it senses moisture on the windshield. The pauses between wiper turns depend not
only on the sensitivity setting, but on the ve­
hicle speed as well.
During brief stops, e.g . at a red light, wiper
motion will automatically be reduced to the
next lower speed . Wipers already turning at
low speed change to intermittent wiping.
When the ignition is turned on, the washer
jets are heated .
A WARNING
-Wiper blades are crucial for safe driving!
Only when they are in good condition are
they able to clear the windows properly
to provide uncompromising visibility.
Worn or damaged wiper blades are a
safety hazard
r=;, page 51, Replacing
windshield wiper blades!
- The light/rain sensor* is only designed to
assist and support the driver.
It remains
entirely the driver's responsibility to
monitor outside weather conditions and
to manually activate the wipers as soon
as rain or drizzle reduces visibility
through the windshield.
- The windshield must not be treated with
water-repellent materials. They can in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter.
Clear vision 49
@ Note
In freezing or near freezing conditions:
- Always check that the wiper blades are
not frozen to the glass before you turn
the wipers on. Loosen a wiper blade
which is frozen in place before operating
the wipers to prevent damage to the
wiper blade or the wiper motor.
- Do not use the wipers to clear a frosted
window. Using the wipers as a conven­ ient ice scraper will destroy the wiper
blades .
- Before you take your vehicle to an auto­
matic car wash, make sure you have the
windshield wiper system switched off (lever in position
0), otherwise the wind­
shield wiper system could get damaged
in the car wash if it should suddenly
come on.
@ Tips
-The windshield wipers are switched off
when the ignition is turned off. Activate
the windshield wipers after the ignition
is switched back on by moving the wind­
shield wiper lever to any position.
- Worn or dirty windshield wiper blades
cause smearing, which can affect the op­
eration of the light/rain sensor*. Check
the condition of your windshield wiper
blades regularly.
-The rain sensor is part of the interval
wiping system. Turning off the ignition
will also deactivate the rain sensor. To re­
activate the sensor, switch off the inter­
val wiping function, then switch it back
on again.
-Applies to vehicles with light/rain sen­
sor: When the wipers are switched on
manually and in rain conditions, the au­
tomatic headlights* turn on
