Useful information
i
This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific differences are possible. Please note
that your vehicle may not be equipped with all
features described. This also applies to
safety-related systems and functions.
iRead the information on qualified specialist
workshops: (Ypage 23).
Loading guidelines
GWARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
GWARNING
If you distribute the load unevenly in the vehi- cle, the handling as well as the steering and
braking characteristics are severely affected.
There is a risk of an accident.
Distribute the load evenly in the vehicle.
Secure the load to prevent it from slipping.
GWARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the rear
door is open when the engine is running, par-
ticularly if the vehicle is moving, exhaust
fumes could enter the passenger compart-
ment. There is a risk of poisoning.
Turn off the engine before opening the rear
door. Never drive with the rear door open.
Driving, braking and steering characteristics
change depending on:
Rtype of load
Rweight
Rthe center of gravity of the load
You should therefore load your vehicle as shown
in the illustrations.
The gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, accessories installed, vehicle occupants
and luggage/load.
Do not exceed the load limit or permitted gross
vehicle weight rating (GVWR) for your vehicle.
The gross load limit and the GVWR are specified
on the vehicle identification plate on the B-pillar
of the driver's door (
Ypage 288).
Furthermore, the load must be distributed in
such a way that the weight on each axle never
exceeds the gross axle weight rating (GAWR) for
the front and rear axles. The specifications for
GVWR and GAWR are on the vehicle identifica-
tion plate on the B-pillar of the driver's door
(
Ypage 288).
Further information can be found in the "Loading
the vehicle" section (
Ypage 271).

Emergency call
Important safety notes
GWARNING
If the indicator lamp in the SOS button is
flashing continuously and there was no voice
connection to the Response Center estab-
lished, then the mbrace system could not ini- tiate an emergency call (e.g. the relevant cel-
lular phone network is not available).
The message Call Failed
appears in the
multifunction display for approximately
10 seconds.
Should this occur, assistance must be sum-
moned by other means.
!You must have a license agreement to acti-
vate the mbrace service. Ensure that your
system is activated and ready for use, and
press the EMB Info call button to register.
If one of these steps is not carried out, it may
not be possible to activate the system.
