Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could release the parking brake and/or
move the gear selector lever from
positionP, either of which could result in an
accident and/or serious injury.
Warning!
G
Getting out of your vehicle with the gear se-
lector lever not fully engaged in positionP is
dangerous. Also, when parked on an incline,
positionP alone may not prevent your vehi-
cle from moving, possibly hitting people or
objects.
Always set the parking brake in addition to
shifting to positionP (
page 49).
When parked on an incline, turn front wheels
towards the road curb.
iAlways set the parking brake in addi-
tion to shifting to positionP.
On slopes, turn the front wheels to-
wards the road curb. iThe SmartKey can only be removed
from the starter switch with the gear
selector lever in positionP.

79 Safety and Security
Driving safety systems
Driving safety systems
In 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)
Electrohydraulic brake system
ABS
The Antilock Brake System (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.
On slippery road surfaces, the ABS will re-
spond even to light brake pressure.
iIn winter operation, the maximum ef-
fectiveness of the ABS, the BAS, the
ESP
®, and the electrohydraulic brake
system is only achieved with winter
tires (page 287) or snow chains as
required.
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 electrohydraulic
brake system cannot reduce 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.
