headlights are off .
Be aware of the following d ifference between
mode ls built to US o r Canadian specifications :
• USA models : illumination of the instrument cluster (gauges and
needles), da sh and c enter console around the g earshift lever is
controlled by a light sensor located in the instrument panel. The
instrum ent panel illumination will automat ically become dimmer
as the d aylight fades awa y and eventually will go out completely
when out side light i s very low . Th is is to remind you, the driver , to
switch on the headlights before it gets too dark .
• Canada models: instrument panel illumin ation will stay bright
r egardless of the intensity of ambient light. Always be awa re of
change s in out side light condition s while you are driving. Re spond
i n time to f ading daylight by turning the light sw itch to position
j D
(or "AUTO " if your car is eq uipped w ith this fea ture) to turn on your
headlights. •
Tachometer (engine rev counter)
The tachometer indica tes the engine RP M (revolutions
per minutes) .
The tachomete r© ::::, fig . 2 is the left one of the two large clo ck-type
displays .
The engine turns at a speed 1 000
times the single digit in the
display, e .g . if the need le points at the "2", the engine tu rns at
2 000 RPM .

-Turn the light switch to 0.
The headlights only work when the ignition is switched on . While
starting the engine or when switching off the ignition, the headlights
w ill go off and only the side marker lights will be on.
Daytime running lights (DRL) (USA models)
The daytime running lights can be turned on or off using this func ­
tion. If the function is active, the daytime running lights are turned
on automat ically when the ignition is switched on .
The daytime running lights are activated
only when the light switch is
at the
AUTO* or DRL * position .
Daytime running lights (Canada models only)
The daytime running lights are act ivated only when the light switch
~ fig. 49 is either at the O or the ~oa; position.
The daytime running lights function cannot be turned off.
Automatic headlight control*
In the switch position AUTO the automatic headlight control is
turned on . The low beams are turned on automatically through a light
sensor as soon as ambient brightness (e.g . when driving into a
tunnel) falls below a value preset at the factory. When ambient .,_

brightness increases again, the low beams are turned off again auto­
matically =>& .
In the
AUTO position the low beams are switched off automatically
when the ignition is turned off.
Light Sensor Malfunction*
In the event of a light sensor ma lfunct ion, the driver is notified in the
instrument cluster display:
Automatic headlights/automatic wipers defective
For safety reasons the low beams are turned on permanently with t he
switch in
AUTO*. H owever, you can continue to turn the lights on and
off using the light switch. Have the light sensor checked as soon as
possible at a dealership.
Coming home/leaving home function*
The function is sw itched on when the sw itch is in the AUTO* position
and the function is shown as active in the driver information system.
The
coming home funct ion illuminates the area around the vehicle
when the ign it ion is switched
off and the driver's door is opened. The
length of time the lights rema in on can be set in the menu display
( Illumination > Exterior lights > coming home ).
The leaving home function illuminates the area around the vehicl e
when u nlocking it .
& WARNING
• Never use daytime running lights to see where you are going.
They are not bright enough and will 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 driver .
They do not relieve the driver of his respon sibility to check the
headlights and to turn them on manually according to the current
light and visibility conditions. For example, fog and rain cannot be

detected by the light sensors. So always switch on the headlights
under these weather conditions and when driving
in the dark io.
• 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.
(I) Tips
• With the switch in AUTO front fog lights cannot be turned on in
addition.
• Th e light senso r for headlight control is located in the rear view
mirror mount . Do not apply any stickers to the windshield in this area
to prevent malfunctions or fail ures .
• Some exterior lighting functions can be adjusted in the driver
information system => page 22 ,
• If you remove the ignition from t he ignition lock whi le the head­
lights are still on, a buzzer will sound as long as the driver's door is
open to remind you to turn off the lights .
• Always observe the specific local regulat ions for your area as to
when to use your lights.
• With automatic headlights, the high-beam funct ion is also avail­
able, but with one restr iction:
If you have not switched the high
beams back to low beams during automatic headlig ht operation (for
example, after driving through a tunnel), only the low beams come
on the next time automatic headlights are switched on . To use the
high beams, you first have to pull the high beam lever back and then
push the lever forwa rd again .
• In cool or damp weather, the inside of the headlights, turn signa ls
and ta il lights can fog over due to the temperature difference
between the inside and outside. They will clear shortly after switching
them on. This does not affect the serv ice life of the light ing . _,,

• Frequent use of the coming home/leaving home function for
approaching and departing a vehicle parked in the dark will strain the
battery. This applies particularly if only short distances are drive n
between stops. Occasionally drive longer distances to make sure the
battery is recharged sufficiently .•

head lights from rearward approaching vehicles). Even in d imming
mode, the mirror surface turns br ight when:
• the interior light is switched on
• reverse gear is engaged.
& WARNING
Broken glass of automatic dimming mirror can cause electrolyte
fluid leakage . Electrolyte fluid can irritate skin , eyes, and respira­
tory system .
• Repeated or p rolonged expo sur e to electrolyte can cau se irrita­
tion to the resp iratory system, esp ecially among people with
asthma or other r espiratory conditions. Get fre sh air immediately
by le aving the vehicl e or, if that is not po ssible , open window s and
doors all the wa y.
• If ele ctrolyte gets into the eye s, flush them thoroughly with
large am ount s of clean water f or at lea st 15 minute s; medical
attention is re commended .
• If electrolyte contacts skin , flush affected area with clean
water for at l east 15 minutes and then wash aff ected area with
s oap and water; medical attention is rec ommended . Thoroughly
wash affected clothing and shoe s before reu se.
• If swallowed and person i s con sciou s, rinse mouth with water
for at least 15 minutes. Do not induce vomit ing unle ss instru cted
to do so by medical profe ssional. Get medical attenti on immedi­
ate ly .
0 Note
Liquid e lectrolyte leaked from a broken mir ror g lass will damage any
plastic surfaces it comes in contact with. Clean up spi lled electrolyte
immediately with clear wate r and a sponge.
[I) Tips
• Check to make su re t he re are no obje cts preventing light from
reac hing the inside mirror.
• Do not attach any st ick er s to the w indshield in front of the light
sensor, as this would interfere with the a utomatic operation of the
head lights and the a utomat ic dimming of the inside mir ror. •
