SmartKey from the starter switch and lock
the vehicle. Do not leave children unattend-
ed in the vehicle, or with access to an un-
locked vehicle. Unsupervised use of vehicle
equipment may cause an accident and/or
serious injury.
66 Safety and SecurityOccupant safetyPreventive occupant safety (PRE-SAFE)
Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations:
You execute an emergency braking ma-
neuver and the Brake Assist System
(page 78) is activated.
The PRE-SAFE system detects a critical
driving dynamics situation.In such cases, the following systems are
automatically activated:
The front seat belts are pre-tensioned.
If the front passenger seat or rear seats
are in an unfavorable position, they are
adjusted to a better position. Rear seat
a d j u s t m e n t o c c u r s o n l y i n v e h i c l e s w i t h
individual seats* in the rear.
The sliding/pop-up roof closes if the
vehicle is in a severe skid or is spin-
ning.
If the seat belts do not release:
Adjust the backrest or seat slightly to
the rear until the seat belt tension is di-
minished.
The locking mechanism releases.
Warning
G
The PRE-SAFE system is intended to reduce
the effects of an accident on properly seat
belted vehicle occupants. Despite having
the PRE-SAFE systems in your car, the pos-
sibility of injuries occurring as a result of an
accident cannot be totally eliminated.
Therefore you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
iThe PRE-SAFE systems are activated at
speeds exceeding 22 mph (35 km/h).
When the driving dynamic situation has
passed without an accident occurring,
the pre-tensioning on the seat belts is
deactivated.
You can then adjust the seats and the
sliding sunroof to their previous posi-
tion.
76 Safety and SecurityDriving safety systems
Driving safety systemsIn this section you will find information on
the following driving safety systems:
ABS (A
ntilock B
rake S
ystem)
BAS (B
rake A
ssist S
ystem)
ESP (E
lectronic S
tability P
rogram)
4MATIC (Four Wheel Electronic Trac-
tion System)
ABS
The ABS regulates the brake pressure so
that the wheels do not lock during braking.
This allows you to maintain the ability to
steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode. Keep firm and steady
pressure on the brake pedal while experi-
encing the pulsation.
iIn winter operation, the maximum ef-
fectiveness of the ABS, ESP and the
4MATIC is only achieved with winter
tires (M + S tires) or snow chains as re-
quired.
Warning!
G
The following factors increase the risk of ac-
cidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following another vehicle too closely
The ABS, BAS, ESP, and 4MATIC cannot re-
duce this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.
77 Safety and Security
Driving safety systems
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure. The
pulsating brake pedal can be an indication
of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.The
-
indicator lamp in the instrument
cluster lights up when you turn the
SmartKey in the starter switch to
position2 or press the KEYLESS-GO* (if so
equipped) start/stop button twice. It goes
out when the engine is running.
For more information, see “Practical hints”
(
page 289).
iTo alert following vehicles to slippery
road conditions you discover, operate
your hazard warning flashers as appro-
priate.
Warning!
G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction. The
ABS cannot prevent accidents, including
those resulting from excessive speed in
turns, following another vehicle too closely,
or hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ABS equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.
