indicator lampInfants and small children should never
share a seat belt with another occupant.
During an accident, th ey could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
Children too big for ch ild restraint systems
must ride in back seats using regular seat
belts. Position shoulder belt across chest
and shoulder, not face or neck.
A booster seat may be necessary to achieve
proper seat belt positioning for children
from 41 lbs until they reach a height where
a lap/shoulder belt fits properly without a
booster.When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle; even if the ch ildren are secured in a
child restraint system. Unsupervised
children in a child rest raint system may use
vehicle equipment and may cause an
accident and/or serious personal injury.

Driving safety systems
Switching off the ESP®
To improve the vehicle’s traction, switch
off the ESP® in driving situations where it
would be advantageous to have the drive
wheels spin and thus cut into surfaces for
better grip such as:
when driving with snow chains
in deep snow
sand or gravel
when driving off-road When you switch off the ESP
®
the ESP® does not stabilize the vehicle
the engine output is not limited, which
allows the drive wheels to spin and
thus cut into surfaces for better grip
the 4-ETS will still apply the brake to a
spinning wheel
the ESP® continues to operate when
you are braking
you cannot activate the cruise control
system
the cruise control system switches off
if currently activated The ESP
® switch is located on the upper
part of the center console.
1 ESP
® switch
With the engine running, press
switch 1.
The ESP
® warning lamp v in the
instrument cluster comes on.
The ESP
® is deactivated.
Warning!G
The ESP® should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.
Warning!G
Switch on the ESP® immediately if the afore-
mentioned circumstances do not apply any-
more. Otherwise the ESP
® will not stabilize
the vehicle when it is starting to skid or a
wheel is spinning.
iWhen the ESP® is switched off and one or
more drive wheels are spinning, the ESP® warn-
ing lamp v in the instrument cluster flashes.
However, the ESP
® will then not stabilize the
vehicle.
