G
When leaving the vehicle, always remove the 
SmartKey or the SmartKey with 
KEYLESS-GO* 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 release the parking brake, which 
could result in an accident and/or serious 
injury.
Warning!
G
It is dangerous to shift the gear selector le-
ver out ofP orN if the engine speed is high-
er than idle speed. If your foot is not firmly 
on the brake pedal, the vehicle could accel-
erate quickly forward or in reverse. You 
could lose control of the vehicle and hit 
someone or something. Only shift into gear 
when the engine is idling normally and when 
your right foot is firmly on the brake pedal.
Warning!
G
On slippery road surfaces, never downshift 
in order to obtain braking action. This could 
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.!In order to avoid damage to the trans-
mission:
Wait for the gear selection process 
to complete before setting the vehi-
cle in motion.
Place the gear selector lever in 
positionD orR only when the vehi-
cle is stopped.

When leaving the vehicle, always remove the 
SmartKey or the SmartKey with 
KEYLESS-GO* from the starter switch, take 
it with you, and lock the vehicle. Do not 
leave children unattended in the vehicle, or

move the gear selector lever from 
positionP, either of which could result in an 
accident and/or serious injury.
Warning!
G
Getting out of your vehicle with the gear se-
lector lever not fully engaged in positionP is 
dangerous. Also, when parked on an incline, 
positionP alone may not prevent your vehi-
cle from moving, possibly hitting people or 
objects.
Always set the parking brake in addition to 
shifting to positionP (
page 167).
When parked on an incline, also turn front 
wheels towards the road curb.
