WARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child's unsupervised
access to a vehicle
could result in an accident
and/or serious personal injury. The children
could:
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
ignition lock or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned on these
parts. G
WARNING
Do not carry heavy or hard objects in the
passenger compartment or trunk
unless they
are firmly secured in place.
Unsecured or improperly positioned cargo
increases a child's risk of injury in the event
of
R strong braking maneuvers
R sudden changes of direction
R an accident
We recommend that all infants and children
be properly restrained using the infant or
child restraint systems at all times while the
vehicle is in motion. Always use a child restraint system that is
compatible with BabySmart™ on the front-
passenger seat.
The use of
infant
or child restraints is required
by law in all 50 states, the District of
Columbia, all U.S. territories and all Canadian
provinces.
Infants and small children must be seated in
an appropriate infant or child restraint system
recommended for the size and weight of the
child. The infant or child restraint system
must be properly secured in accordance with
the manufacturer's instructions. All infant or
child restraint systems must comply with U.S.
Federal Motor Vehicle Safety Standards 213
and 225 and Canadian Motor Vehicle Safety
Standards 213 and 210.2.
An information label on the child restraint
system indicates whether it meets these
standards. This confirmation can also be
found in the installation instructions that are
included with the child restraint system.
Always read and follow the manufacturer's
instructions when using an infant or child
restraint system or booster seat.
Observe the warning labels in the vehicle
interior or on the infant or child restraint.
If an infant or child is traveling in the vehicle:
X Secure the child with a child or infant seat
restraint system appropriate to
the age and
weight of the child.
X Make sure that the infant or child is
properly secured at all times while the
vehicle is in motion.

When children ride on the vehicle's rear seats,
activate the override switch. Otherwise, the
children could be injured, e.g. by trapping
themselves in the rear side window. G
WARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child's unsupervised
access to a vehicle
could result in an accident
and/or serious personal injury. The children
could:
R injure themselves on parts of the vehicle
R be seriously or fatally injured through

If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very hot, and the child could be burned on these
parts.
Child-proof locks for the rear doors G
WARNING
Children could open a rear door from inside
the vehicle. This could result in serious
injuries or an accident. Therefore, when
children ride in the
rear always secure the rear
doors with the child-proof locks.
You secure each door individually with the
child-proof locks on the rear doors. A door
secured with a child-proof lock cannot be
opened from inside the vehicle. When the
vehicle is unlocked, the door can be opened
from the outside. X
To activate: press the child-proof lock
lever down in the direction of arrow 0044.
X Make sure that the child-proof locks are
working properly.
X To deactivate: press the child-proof lock
lever up in the direction of arrow 0043.

Driving safety systems overview
In this section, you
will find information about
the following driving safety systems:
R ABS ( Anti-lock Braking System)
(Y page 61)
R BAS ( Brake Assist System) ( Y page 61)
R Adaptive brake lamps (Y page 62)
R ESP ®
(Electronic Stability Program)
(Y page 62)
R EBD ( electronic brake force distribution)
(Y page 64)
R ADAPTIVE BRAKE(Y page 64)
R Trailer stabilization Important safety notes
G
WARNING
The ABS, the BAS, and the ESP ®
switch off
when the differential locks are switched on.
When the ABS, the BAS, and the ESP ®
are
switched off
R wheels may lock during hard braking
R steering capabilities are reduced
R braking distance is increased
R vehicle stability in standard driving
maneuvers is increased
Make sure the differential
locks are switched
on at all times except when driving off-road
for example. Switch on the differential locks
immediately when returning from off-road
driving.
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road and weather
conditions and maintain a safe distance from
the vehicle in front. Drive carefully.
i Please note that the driving safety
systems described only work as effectively
as possible if there is adequate contact
between the tires and the road surface. Pay
particular attention to the information
regarding tires, recommended minimum
tire tread depths etc. in the "Wheels and
tires" section (Y page 318).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible. 60
