Automatic anti-glare mirrors
GWARNING
Electrolyte may escape if the glass in an auto-
matic anti-glare mirror breaks. The electrolyte
is harmful and causes irritation. It must not
come into contact with your skin, eyes, res-
piratory organs or clothing or be swallowed.
There is a risk of injury.
If you come into contact with the electrolyte,
observe the following:
RRinse off the electrolyte from your skin
immediately with water.
RImmediately rinse the electrolyte out of
your eyes thoroughly with clean water.
RIf the electrolyte is swallowed, immediately
rinse your mouth out thoroughly. Do not
induce vomiting.
RIf electrolyte comes into contact with your
skin or hair or is swallowed, seek medical
attention immediately.
RImmediately change out of clothing which
has come into contact with electrolyte.
RIf an allergic reaction occurs, seek medical
attention immediately.
The rear-view mirror and the exterior mirror
on the driver's side automatically go into anti-
glare mode if the following conditions are met
simultaneously:
Rthe ignition is switched on and
Rincident light from headlamps strikes the
sensor in the rear-view mirror.
The mirrors do not go into anti-glare mode if
reverse gear is engaged or if the interior light-
ing is switched on.

ments, make sure that no one has any body
parts in the sweep of the seat or steering
wheel. If somebody becomes trapped, imme-
diately release the memory function position
button. The adjustment process is stopped.
GWARNING

vate the memory function, particularly when
unattended. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The memory function can be used at any time,
e.g. even when the SmartKey isn't in the igni-
tion lock.

Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched
on even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations.
Setting the exterior lighting
Setting options
Exterior lighting can be set using:
Rthe light switch
Rthe combination switch (Ypage 125)

RSmartKey in position 1in the ignition lock:
the parking lamps are switched on or off
automatically depending on the brightness
of the ambient light.
RWith the engine running: if you have acti-
vated the daytime running lamps function

running lamps or the parking lamps and the
low-beam headlamps are switched on or off
automatically depending on the brightness
of the ambient light.
XTo switch on automatic headlamp
mode: turn the light switch to Ã.
Only for Canada:
The daytime running lamps improve the visi-
bility of your vehicle during the day. The day-
time running lamps function is required by law
in Canada. It cannot therefore be deactivated.
When the engine is running and the vehicle is
stationary: if you move the selector lever from
a drive position to P, the daytime running lamps/low-beam headlamps go out after
three minutes.
When the engine is running, the vehicle is
stationary and in bright ambient light: if you
turn the light switch to
T, the daytime
running lamps and parking lamps switch on.
If the engine is running and you turn the light
switch to L, the manual settings take
precedence over the daytime running lamps.
USA only:
The daytime running lamps improve the visi-
bility of your vehicle during the day. To do this,
the daytime running lamps function must be
switched on using the on-board computer
(
Ypage 233).

nd you turn the light
switch to TorL, the manual settings
take precedence over the daytime running

Low-beam headlamps
GWARNING
When the light switch is set to Ã, the low-
beam headlamps may not be switched on

Hazard warning lamps
XTo switch on the hazard warning lamps:
press button :.
All turn signals flash. If you now switch on a
turn signal using the combination switch,
only the turn signal lamp on the corre-
sponding side of the vehicle will flash.
XTo switch off the hazard warning lamps:
press button :.
The hazard warning lamps automatically
switch on if:
Ran air bag is deployed or
Rthe vehicle decelerates rapidly from a
speed of above 45 mph (70 km/h) and
comes to a standstill
The hazard warning lamps switch off auto-
matically if the vehicle reaches a speed of
above 6 mph (10 km/h) again after a full
brake application.
iThe hazard warning lamps still operate if
the ignition is switched off.
Cornering light function
The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better vis-
ibility in tight bends, for example. The corner-
ing light function can only be activated when
the low-beam headlamps are switched on.
Active:
Rif you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
Rif you are driving at speeds between
25 mph (40 km/h) and 45 mph (70 km/h)
and turn the steering wheel
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.
Active light function
The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
126Exterior lighting

driving. This allows you to identify pedes-
trians, cyclists and animals.
Active:when the lights are switched on.
Adaptive Highbeam Assist
General notes
You can use this function to set the head-
lamps to change between low beam and high beam automatically. The system recognizes
vehicles with their lights on, either approach-
ing from the opposite direction or traveling in
front of your vehicle, and consequently
switches the headlamps from high beam to
low beam.
The system automatically adapts the low-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel.
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognize
road users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
may fail to recognize other road users that
have lights, or may recognize them too late. In this or similar situations, the automatic high-
beam headlamps will not be deactivated or
activated regardless. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. Youare responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and
traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
Rpoor visibility, e.g. due to fog, heavy rain or
snow
Rdirt on the sensors or the sensors are
obscured

Replacing the wiper blades
Important safety notes
GWARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
!Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.
!Always position the windshield wiper
arms vertically before folding them away
from the windshield. By doing so, you will
avoid damage to the hood.
