You have properly stopped and parked 
your vehicle. End your drive as follows.Warning!
G
With the engine not running, there is no 
power assistance for the brake and the 
steering system. In this case, it is important 
to keep in mind that a considerably higher 
degree of effort is necessary to brake and 
steer the vehicle.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or 
leaves can come into contact with the hot 
exhaust system, as these materials could be 
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off 
the engine and leaving the vehicle always:
Keep right foot on brake pedal.
Firmly depress parking brake pedal.
Shift the automatic transmission to 
positionP.
Slowly release brake pedal.
When parked on an incline, turn front 
wheel towards the road curb.
Turn the SmartKey to starter switch 
position0 and remove, or press

SmartKey or SmartKey with KEYLESS-GO* 
from the starter switch, take it with you and 
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an 
unlocked vehicle. Children could release the 
parking brake and/or shift the automatic 
transmission out of positionP, either of 
which could result in an accident and/or se-
rious personal injury.
Warning!
G
Getting out of your vehicle with the 
automatic transmission not fully engaged in 
positionP is dangerous. Also, when parked 
on an incline, positionP alone may not pre-
vent your vehicle from moving, possibly hit-
ting people or objects.
Always set the parking brake in addition to 
shifting to positionP (
page 185).
When parked on an incline, also turn front 
wheel towards the road curb.

66 Safety and SecurityOccupant safetyIn this section you will learn the most im-
portant facts about the restraint systems 
of the vehicle.
Seat belts (
page 73)
Child restraints (
page 87)
Lower anchors and tethers for children 
(LATCH) (
page 88)
Supplemental Restraint System (SRS) with
Air bags (
page 67)
Air bag control unit (with crash 
sensors)
Emergency tensioning device (ETD) for 
seat belts (
page 76)Air bag system components with
Front passenger front air bag off 
indicator lamp (
page 85)
Front passenger seat with Occupant 
Classification System (OCS) 
(page 81)
As independent systems, their protective 
functions work in conjunction with each 
other.The SRS system conducts a self-test when 
the ignition is switched on and in regular 
intervals while the engine is running. This 
facilitates early detection of malfunctions. 
The 
1
indicator lamp in the instrument 
cluster (page 25) comes on when the 
ignition is switched on and goes out no lat-
er than a few seconds after the engine has 
been started.
The SRS components are in operational 
readiness if the 
1
indicator lamp is not 
lit when the engine is running.
A malfunction in the system has been 
detected if the 
1
indicator lamp:
fails to go out not later than approxi-
mately four seconds after the engine 
was started
does not come on at all
comes on after the engine was started 
or while driving
