Warning!
G
It is dangerous to shift the gear selector le-
ver out ofPorN if the engine speed is high-
er than idle speed. If your foot is not firmly 
on the brake pedal, the vehicle could accel-
erate quickly forward or in reverse. You 
could lose control of the vehicle and hit 
someone or something. Only shift into gear 
when the engine is idling normally and when 
your right foot is firmly on the brake pedal.!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes 
premature brake and drivetrain wear.
Warning!
G
On slippery road surfaces, never downshift 
in order to obtain braking action. This could 
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.!Place the gear selector lever in 
positionR only when the vehicle is 
stopped in order to avoid damaging the 
transmission.!Do not run cold engine at high engine 
speeds. Running a cold engine at high 
engine speeds may shorten the service 
life of the engine.

Warning!
G
The BabySmart
TM airbag deactivation sys-
tem will ONLY work with a special child seat 
designed to operate with it. It will not work 
with child seats which are not BabySmart
TM 
compatible.
Never place anything between seat cushion 
and child seat (e.g. pillow), since it reduces 
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must 
make full contact with the passenger seat 
cushion. An incorrectly mounted child seat 
could cause injuries to the child in case of an 
accident, instead of protecting the child.
Follow the manufacturer’s instructions for 
installation of special child seats.
Warning!
G
When using a BabySmart
TM compatible 
child seat on the front passenger seat, the 
passenger front airbag will not deploy only if 
the PASS. AIRBAG OFF indicator lamp re-
mains illuminated. 
Please make sure to check the indicator ev-
ery time you use the special system child 
seat. Should the light go out while the re-
straint is installed, please check installation. 
If the light remains out, do not use the 
BabySmart
TM restraint to transport children 
on the front passenger seat until the system 
has been repaired.

77 Safety and Security
Driving safety systems
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 with light brake pressure.The - indicator lamp in the instrument 
cluster (
page 22) comes on when you 
turn the SmartKey in the starter switch to 
position2 or press the KEYLESS-GO* 
start/stop button twice. It goes out when 
the engine is running.
Braking
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 experiencing the pul-
sation.Continuous, steady brake pedal pressure 
yields the advantages provided by the ABS, 
namely braking power and the ability to 
steer the vehicle.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and 
functions as a reminder to take extra care 
while driving.
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.
