Th er iskofana ccident is significantly

ularly the case when cornering on we tand
slippery roads and when driving too close
to the vehicl einfront.
Th ed riving safety systems describe dinthis
sectio ncannot reduc ethisr iskn or override
the laws of physics. For thi
sreason, always adap tyou rd riving
style to suit prevailing roa dand weather
conditions .Maintain sufficient distance
fro mo ther roa dusers and objects on the
road. ABS (Anti-lock Braking System)
ABS regulate sbrake pressure in such away
tha tthe wheels do not lock when yo ubrake.
This allows yo utocontinue steering the vehi-
cle when braking.
ABS works fro maspeed of abou t8km/h
upwards ,regardles sofroads urface condi-
tions. ABS works on slippery surfaces ,even
when yo uonlyb rake gently. G

BAS operates in emergency braking situa-
tions. If yo udepress the brake peda lquickly,
BAS automaticall yboost sthe braking force,

to forc
ethe door to close. You could oth-
erwise damage the door or the window. Locking/unlocking the vehicle from
the inside
You can centrally lock or unlock the vehicle
from the inside. This feature may be useful if,
for example, you wish to unlock the
passenger door from the inside or lock the
vehicle before you pull away. G
Risk of accident
Do not leave children unsupervised in the
vehicle. They could open adoor from the
inside –even if it is locked –and thereby
endanger themselves and others. 1

The vehicle will lock automatically once you
have pulleda way.
You can switch off the automatic locking
function via the on-board computer
(Y page 120).
i The vehicle is locked automatically when
the ignition is switched on and the wheels

Risk of poisoning
Exhaust fumes could enter the vehicle inte-
rior if the engine is running and the boot lid
is open. This could poison you. Therefore,
you should make sure that the boot lid is
always closed when the engine is running.
