Getting out of your vehicle with the gear 
selector lever not fully engaged in positionP 
is dangerous. Also, positionP alone is not 
intended to or capable of preventing your 
vehicle from moving, possibly hitting people 
or objects.
Always set the parking brake in addition to 
shifting to positionP (
page 51).
When parked on an incline, turn the front 
wheels towards the road curb.
Do not park this vehicle in areas where 
combustible 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.
Warning!

When leaving the vehicle, always remove the 
SmartKey from the starter switch, take it 
with you and lock the vehicle. Do not leave 
children unattended in the vehicle, or with 
access to an unlocked vehicle. Children 
could move the gear selector lever from 
positionP, which could result in an accident 
and/or serious personal injury.
!Never change the program mode when 
the gear selector lever is out of 
positionP. This could result in a 
change of driving characteristics for 
which you may not be prepared.
