When the corresponding function in the
control system is activated (
page 185):
The exterior rear view mirrors automat-
ically fold in as soon as the vehicle is
locked from the outside.
The exterior rear view mirrors automat-
ically fold out as soon as the vehicle is
unlocked and the driver’s or front pas-
senger door are subsequently opened.
Warning!G
The auto-dimming function does not react if
incoming light is not aimed directly at sen-
sors 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, when transporting cargo
which covers the rear window.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic con-
ditions and could cause an accident.
Warning!G
Exercise care when using the passen-
ger-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
interior rear view mirror or glance over your
shoulder before changing lanes.
!Before you drive the vehicle through an
automatic car wash, fold the exterior rear view
mirrors in. Otherwise they may get damaged.

Emergency calls
An emergency call is initiated automatical-
ly following an accident in which the emer-
gency tensioning devices (ETDs) or
air bags deploy.
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 (
page 335) for
instructions on initiating an emergency call
manually.Once the emergency call is in progress, the
indicator lamp on the SOS button will
begin to flash. The message
Connecting call appears in the multifunc-
tion display. When the connection is estab-
lished, the message
Call connected
appears in the multifunction display. All in-
formation relevant to the emergency, such
as the location of the vehicle (determined
by the GPS satellite location system), vehi-
cle model, identification number and color
are generated.
A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
The Response Center will attempt to
determine more precisely the nature of the
accident provided they can speak to an
occupant of the vehicle.The Tele Aid system is available if
it has been activated and is operation-
al. Activation requires a subscription
for monitoring services, connection
and cellular air time
vehicle battery power is available
the relevant cellular phone network
and GPS signals are available and pass
the information on to the Response
Center
iLocation of the vehicle on a map is only pos-
sible if the vehicle is able to receive signals from
the GPS satellite network and pass the informa-
tion on to the Response Center.

Step 1:
Switch on the ignition (page 42).
Warning!G
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent po-
tential harm or damage. When programming
a garage door opener, the door moves up or
down. When programming a gate operator,
the gate opens or closes.
Do not use the integrated remote control
with any garage door opener that lacks
safety stop and reverse features as required
by U.S. federal safety standards (this
includes any garage door opener model
manufactured before April 1, 1982).
A garage door that cannot detect an object
– signaling the door to stop and reverse –
does not meet current U.S. federal safety
standards.
When programming a garage door opener,
park the vehicle outside the garage.
Do not run the engine while programming
the integrated remote control. Inhalation of
exhaust gas is hazardous to your health.
All exhaust gas contains carbon monoxide
(CO), and inhaling it can cause unconscious-
ness and possible death.

Driving instructions
Close all doors and the tailgate.
Attach the trailer.
Plug in all electrical connectors.
Towing a trailer
There are many different laws, including
speed limit restrictions, having to do with
trailer towing. Make sure your rig will be le-
gal, not only for where you reside, but also
for where you will be driving. A good
source for this information can be the po-
lice or local authorities.Note the following points, when driving
with the trailer:In order to gain skill and an understand-
ing of the vehicle’s behavior, you
should practice turning, stopping and
backing up in an area which is free from
traffic.
Before you start driving check the
trailer hitch
break-away switch
safety chains
electrical connections
lighting and tires
Adjust the mirrors (page 52) to
permit unobstructed view beyond rear
of trailer.
If the trailer has electric brakes, start
your vehicle and trailer moving slowly,
and then apply only the trailer brake
controller by hand to make sure the
brakes are working properly.
Always secure items in the trailer to
prevent load shifts while driving.
When towing a trailer, check occasion-
ally to make sure the load is secure,
and that lighting and trailer brakes (if
so equipped) are functioning properly.
Take into consideration that when tow-
ing a trailer, the handling characteris-
tics are different and less stable from
those when operating the vehicle with-
out a trailer.
It is important to avoid sudden maneu-
vers.
The vehicle and trailer combination is
heavier, and therefore is limited in ac-
celeration and climbing ability, and re-
quires longer stopping distances.
It is more prone to reacting to cross
wind gusts, and requires more sensi-
tive steering input.
If possible, do not brake abruptly, but
rather engage the brake slightly at first
to permit the trailer to activate its
brake. Then increase the braking force.
iWhen you are towing a trailer, the vehicle
level always remains in the Highway setting.
The following applies additionally when towing a
trailer:
The vehicle is lowered to the highway level
when it reaches a speed of 5 mph (8 km/h)
if not set to highway level.
The high-speed level is not available.
The restrictions that apply to towing also apply
when using accessories that are connected to
the trailer power socket, such as a bicycle rack.

Vehicle care
Automatic car wash
You can have your car washed in an auto-
matic car wash from the start. Automatic
car washes without brushes are prefera-
ble.
To protect the filter system, switch the
climate control system (
page 218) or
the automatic climate control system*
(
page 232) to air recirculation mode.
If the vehicle is very dirty, prewash it
before running it through the automatic
car wash.When taking the vehicle through an auto-
matic conveyor type car wash, observe the
following instructions.Vehicles with SmartKey:
With the vehicle at a standstill and the
ignition switched on shift the automatic
transmission to neutral positionN.
If engaged, release the parking brake
(
page 60).
Switch off the ignition and leave the
SmartKey in the starter switch.
Vehicles with KEYLESS-GO*:
With the vehicle at a standstill, depress
the brake pedal and keep it pressed.
With the ignition switched on shift the
automatic transmission to park
positionP.
Release the brake pedal.
Remove the KEYLESS-GO* start/stop
button from the starter switch
(
page 43).
!Do not clean your vehicle in an automatic
touchless car wash which use caustic spray.
Otherwise the caustic spray will damage the
paint or ornamental moldings.
!Make sure that the windshield wiper switch
is set to0 (
page 64). Otherwise, e.g. the rain
sensor could activate and cause the wipers to
move unintentionally. This may lead to vehicle
damage.
Due to the width of the vehicle, fold in exterior
rear view mirrors prior to running the vehicle
through an automatic car wash to prevent
damage to the mirrors.
Warning!G
When leaving the SmartKey or SmartKey
with KEYLESS-GO* in the starter switch, do
not leave children unattended in the vehicle.
It is possible for children to switch on the
ignition which could result in unsupervised
use of vehicle equipment. Unsupervised use
of vehicle equipment could result in an
accident and/or serious personal injury.
