KEYS AND DOORS
If the vehicle is subjected to a severe frontal, rear or side
impact with the ignition switch turned to the "ON" position, both
side doors will unlock automatically after a few seconds.
CAUTION
Before driving, make sure the doors are closed and
locked, especially when small children are in the
vehicle. Along with the proper use of seat belts, locking
the doors helps prevent the driver and passengers from
being thrown out from the vehicle during an accident.
It also helps prevent the doors from being opened
unintentionally.
