Door Locks
CAUTION:
Unlocked doors can be dangerous.
Passengers -- especially children -- can easily
open the doors and fall out. When a door is
locked, the inside handle won’t open it.
Outsiders can easily enter through an unlocked
door when you slow down or stop your vehicle.
This may not be so obvious: You increase the
chance of being thrown out of the vehicle in a
crash if the doors aren’t locked. Wear safety belts
properly, lock your doors, and you will be far
better off whenever you drive your vehicle.
There are several ways to lock and unlock your vehicle.
From the outside, use your door key or remote lock
control transmitter.
From the inside, to lock the door, rotate the locking
lever forward.
To unlock the door, rotate the locking lever
rearward. There is a red mark on the switch when
the door is unlocked.
Central Door Unlocking System
If the driver’s door key is held in the unlock position for
more than one second, all doors will unlock.
