Important safet ynotes
If you fail to adapt your drivin gstyle or if you are
inattentive ,th edrivin gsafet ysystems can nei-
ther reduce th eris kof an acciden tno roverride
th elaws of physics. Driving safet ysystems are
merely aids designed to assist driving. You are
responsible fo rmaintainin gth edistanc eto th e
vehicle in front, fo rvehicle speed, fo rbraking in
goo dtime, and fo rstayin gin lane. Always adapt
your drivin gstyle to suit th eprevailin groad and
weather condition sand maintain asaf edistanc e
from th evehicle in front. Drive carefully.
The drivin gsafet ysystems described only wor k
as effectively as possible when there is ade-
quat econtact between th etires and th eroad
surface. Pay particular attention to th einforma-
tion regardin gtires ,recommended minimum
tire tread depths etc. in th e"Wheels and tires "
section (
Ypage 387).
In wintr ydrivin gconditions, always use winte r
tires (M+ Stires )and ,if necessary, snow chains.
Only in this way will th edrivin gsafet ysystems
described in this section wor kas effectively as
possible.
ABS (Anti-lock Braking System)

uation is over.
XTo make afull brak eapplication: depress
th ebrake peda lwit hfull force.
If AB Sintervenes when braking ,you will feel a

Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.

RStart the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
If you attach heavy or large objects to the
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to theSmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
!Keep the SmartKey away from strong mag-
netic fields. Otherwise, the remote control
function could be affected.
Strong magnetic fields can occur in the vicin-
ity of powerful electrical installations.
Do not keep the SmartKey:
Rwith electronic devices, e.g. a mobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of the Smart-
Key.
Do not keep the KEYLESS-GO or KEYLESS-GO
Start function key in the temperature-controlled
cup holder. Otherwise, the KEYLESS-GO or KEY-
LESS-GO Start function key will not be detected. Vehicles with KEYLESS-GO start function: do
not keep the SmartKey in the cargo compart-
ment. Otherwise, the SmartKey may not be
detected, e.g. when starting the engine using
the Start/Stop button.
