Rear view mirror
More information on setting the rear view
mirrors can be found in the “Getting start-
ed” section (
page 38).
Automatic antiglare rear view mirror
The reflection brightness of the exterior
rear view mirror on the driver’s side and
the interior rear view mirror will respond
automatically to glare when
the ignition is switched on,
and
incoming light from headlamps falls on
the sensor in the interior rear view mir-
ror.
The rear view mirror will not react if
reverse gear is engaged
the interior lighting is turned on
Warning!
G
The automatic antiglare function does not
react if incoming light is not aimed directly
at sensors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, if the rear window sun
shade* is in raised position.
Glare can endanger you and others.Warning!
G
In the case of an accident, liquid electrolyte
may escape from the mirror housing if the
mirror glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
Warning!
G
Exercise care when using the passenger
side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
terior rear view mirror or glance over your
shoulder before changing lanes.!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state by applying plenty of water.

Driving systems
Parktronic (Parking assist)*
The Parktronic system is an electronic aid
designed to assist the driver during park-
ing maneuvers. It visually and audibly indi-
cates the relative distance between the
vehicle and an obstacle.
The Parktronic system is automatically ac-
tivated when you switch on the ignition
and release the parking brake. The
Parktronic system deactivates at speeds
over approximately 11 mph (18 km/h). At
lower speeds the Parktronic system turns
on again.The Parktronic system monitors the sur-
roundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
1Sensors in the front bumperWarning!
G
Parktronic is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors, es-
pecially at times of snow and ice, see
“Cleaning the Parktronic* system sensors”
(page 301).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers or the air
brakes of trucks) can cause the system to
send erratic indications, and should be tak-
en into consideration.
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.

An emergency call is initiated
automatically:
following an accident in which the
emergency tensioning devices (ETDs)
or airbags deploy
if the anti-theft alarm or the tow-away
alarm stays on for more than
20 seconds, see “Anti-theft systems”
(page 81) and see “Tow-away alarm”
(page 83).
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See below for instructions on
initiating an emergency call manually.
Once the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message

tion display.
iThe Tele Aid system utilizes the cellular
network for communication and the
GPS (Global Positioning System) satel-
lites for vehicle location. If either of
these signals is unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.
