to endanger any other road users when you
engage the parking brake.

SmartKey or 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

either of which could result in an accident
and/or serious personal injury.

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 (
