The driver has a lap-shoulder belt. Here's how to wear
it properly.

Don't let it get twisted.

you very quickly. If this happens, let the belt go back
slightly to unlock it. Then pull the belt across you
more slowly.

Pull up on the latch plate to make sure it is secure.
If the belt isn't long enough, see ªSafety Belt
Extenderº at the end of this section.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

double
-sided key for the
ignition and all door locks.
Your vehicle may also have
a key that locks and unlocks
the center floor console
only (if equipped).
If you ever lose your keys, your dealer will be able to

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.

and the key is in the ignition, all of the doors will lock
and then the driver's door will unlock.
