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.

Daytime running lights (DRL) (USA
models)
T he daytime running lights can be turned on
or off using this function. If the function is ac­
tive, the daytime running lights are turned on
automatically when the ignit ion is switched
on.
The daytime running lights are activated
only
when the light switch is at the AUTO* or DRL *
position.

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 aga in, the low beams are
turned off again automatically ¢.&. .
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 malfunction, the
driver is notified in the instrument cluster dis­
play:
tal Automatic headlights/automatic wipers
defective
For safety reasons the low beams are turned
on permanently with the switch in
AUTO* .
However, you can continue to turn the lights
on and off using the light switch . Have the
Ill>-

light sensor checked as soon as possible at a
dealership.
Adaptive light *
The benefit of adaptive l ight is that the curve
and the edge of the road are better i llum inat­
ed . The adaptive light is contro lled automati­
cally, depending on vehicle speed and steering
wheel angle.
When driving a round bends, the head lights
are contro lled according to steering wheel an­
g le . So that there is no black area ahead of the
ve hic le, the two main beams pivot at different
angles. The system works above a speed of
about 6 mph (10 km/h).
Com ing home /le avi ng home function *
The function is swit ched on when the switch is
in the AUTO* position and the function is
shown as active in the driver information sys­
tem.
The
coming hom e function illuminates the
area around the vehicle when the ign ition is
switched off and the driver's door is ope ned.
The length of time the lights remain on can be
set in the menu display
( Illumination > Exte­
rior lights > coming home ).
The leavi ng home function i lluminates the
area around the vehicle when unlocking it.
A WARNING
- Never use dayt ime running l ights 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 dar k. Always switch on
the low beams at dusk or when i t is dar k.
- Automatic headlights a re only intended
to assist the dr iver. They do not re lieve
t he driver of his responsibi lity to check
t he headlights and to turn them on man­
ually according to the current light and
visibility conditions. 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
jO .
Clear vis ion 49
- 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

- Please observe legal regulat ions w hen
using the ligh ting systems des cribed.
(D Tips
- T he light sensor for head light control is
located in the rear view mirror mount.
Do not apply any stickers to t he wind­
shield in th is area to preven t malfunc­
tions or fa ilures.
- Some exter io r l ighting funct ions can be

- I f you remove the igni tion from t he igni ­
t ion lock while the headligh ts are s till
on, a buzzer wi ll sound as long as the
driver's door is o pen to remind yo u to
t u rn off the lights.
- Always observe the specific local regula ­
tions for your area as to when to use your
lights.
- With automatic headlights, the high­
beam f unction is also available, but w ith
one restrict ion: If you have not sw itched
the high beams back to low beams dur­
ing automatic headlight operation (for
example, after d riving throug h a tunnel),
only the low beams come on the next

l ever is controlled by a light senso r locat­
ed in the instrument panel. The instru­
ment pane l illumination will a utomat i­
cally become dimmer as the daylight
fades away and eventually will go out
complete ly when outside light is very
l ow . Th is is to rem ind you, the driver, to
switch on the headlights before it gets
too dark . -
Canada models: instrument panel illumi­
nation will stay bright 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 tur ning the
light switch to position fD (o r "AUTO" if
your car is equipped with this feature) to
t ur n on you r headlights.
Luggage compartment light
The light is located on the right side of the

You are we ll-advised to fold the exterior mir­
rors in when maneuvering in tight spaces or
when leaving the car parked close to other
vehicles. ..,,.

_& WARNING
- Curved (i. e. convex) mirror surfaces in­
crease your field of view. Remember that
vehicles or other objects will appear
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.
CD 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
the mirrors . Never fold power folding ex­
terior mirrors* by hand. Only fold them in and out using the power controls .
@ Tips
If there should be a malfunction in the
electrical system, you can still adjust the
exterior mirrors by pressing the edge of
the mirror .

trolyte can cause irritation to the respira­
tory system, especially among people
with asthma or other respiratory condi­
tions. Get fresh air immediately by leav­
ing the vehicle or, if that is not possible,
open windows and doors all the way.
- If electrolyte gets into the eyes, flush
them thoroughly with large amounts of
clean water for at least 15 minutes·
. '
medical attention is recommended.
- If electrolyte contacts skin, flush affect­
ed area with clean water for at least 15 minutes and then wash affected area
with soap and water; medical attention is recommended. Thoroughly wash af­
fected clothing and shoes before reuse .
- If swallowed and person is conscious, rinse mouth with water for at least 15
minutes. Do not induce vomiting unless
instructed to do so by medical professio­
nal. Get medical attention immediately .
CD Note
Liquid electrolyte leaking from broken mir­
ror glass will damage any plastic surfaces
it comes in contact with. Clean up spilled
electrolyte immediately with clean water
and a sponge. .,..

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 ¢
page 5 7, 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 .
(I) 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

come on.
(0 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.
