68 Getting started
Parking and locking
Step firmly on parking brake pedal1.
When the engine is running, the
warning lamp; (USA only) or3
(Canada only) in the instrument cluster
comes on.
Switching off headlamps
Turn the exterior lamp switch toM
(
page 61).
For more information, see “Lighting”
(
page 143).
Turning off the engine
Shift the automatic transmission to
positionP (
page 191).
Apply the parking brake (page 67).
Warning!G
When leaving the vehicle, always remove the
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
serious 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
prevent your vehicle from moving, possibly
hitting people or objects.
Always set the parking brake in addition to
shifting to positionP (
page 191).
When parked on an incline, also turn front
wheel towards the road curb.
iIf the engine cannot be turned off as
described, see “Emergency engine shut-down”
(
page 545).
Warning!G
Do not turn off the engine before the vehicle
has come to a complete stop. With the en-
gine not running, there is no power assis-
tance for the brake and steering systems. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to brake and steer the vehicle.
iAlways set the parking brake in addition to
shifting the automatic transmission to positionP
(
page 191).
When parked on an incline, also turn front wheel
towards the road curb.
