Driver Position
This part describes the driver’s restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here’s how to wear it
properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.3. Pick up the latch plate and pull the belt across you.
Don’t let it get twisted.
The shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt isn’t long enough, seeSafety Belt
Extender on page 1-27.
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.
1-12

If your vehicle has one, the driver’s side impact air
bag is in the side of the driver’s seatback closest to
the door.
{CAUTION:
If something is between an occupant and an
air bag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating air bag must be kept clear. Don’t put
anything between an occupant and an air bag,
and don’t attach or put anything on the
steering wheel hub or on or near any other air
bag covering. Don’t let seat covers block the
ination path of a side impact air bag.

Each remote keyless entry transmitter is uniquely coded
to prevent another transmitter from unlocking your
vehicle. If a transmitter is lost or stolen, a replacement
can be purchased through your dealer. Remember
to bring any additional transmitters with you so they also
can be re-coded to match the new transmitter. Once
your dealer has coded the new transmitter, the lost
transmitter cannot unlock the vehicle. The vehicle can
have a maximum of four transmitters coded to it.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not locked. So,
wear safety belts properly and lock the
doors whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock the vehicle.
From the outside, use the door key or remote keyless
entry transmitter. From the inside use the manual
or power door locks.
To manually lock or unlock the driver’s door from the
outside, insert the key and turn it clockwise or
counterclockwise.
To lock or unlock the doors from the inside, push the
manual lock lever forward or rearward.
