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).

- 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

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 .

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.
