Sitting in a reclined position when your vehicle is
in motion can be dangerous. Even if you buckle
up, your safety belts can’t do their job when
you’re reclined like this.
The shoulder belt can’t
do its job because it
won’t be against your body. Instead,
it will be in
front of you. In a crash you could go into it,
receiving neck or other injuries.
The lap belt can’t do its job either. In a crash the
belt could go up over your abdomen. The belt
forces would be there, not
at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle
is in
motion, have the seatback upright. Then sit well
back in the seat and wear your safety belt properly.
~~
Head Restraints
Slide the head restraint up or down so that the top of the
restraint is closest to the top of your ears. This position
reduces the chance of a neck injury in a crash.
Seatback Latches
The front seatback of the base-level bench seat folds
forward
to let you access the rear of the cab. Your
seatback will move back and forth freely, unless you
come to a sudden stop. Then it will lock into place.
If
you have a Crew Cab, your front seatback is designed
not to fold forward. Access to the rear of the cab is
available by using the rear doors.
The front seatback
of the split bench seat and bucket
seats fold forward to let you access the rear of the cab.

Q: If I’m a good driver, and I never drive far from
home, why should I wear safety belts?
A: You may be an excellent driver, but if you’re in an
accident -- even one that isn’t your fault -- you and
your passengers can be hurt. Being
a good driver
doesn’t protect you from things beyond your
control9 such
as bad drivers.
Most accidents occur within
25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds
of less than 40 mph
(65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
Adults
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies.
If a child will be
riding
in your vehicle, see the part of this manual
called “Children.” Follow those rules for
everyone’s protection.
First, you’ll want to know which restraint systems your
vehicle has.
We’ll start
with the driver position.
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 (to see how, see “Seats” in the Index)
so you can sit up straight.

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.

This system has a range of about 3 feet (1 m) up to
30 feet (9 m). At times you may notice a decrease in
range. This is normal for any remote keyless entry
system.
If the transmitter does not work or if you have
to stand closer to your vehicle for the transmitter to
work, try this:
0 Check to determine if battery replacement or
transmitter resynchronization is necessary. See the
instructions that follow.
Check the distance. You may be too far from your
vehicle.
You may need to stand closer during rainy
or snowy weather.
Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.
If you're still having trouble, see your dealer or a
qualified technician for service.
Operation
To unlock the driver's door, press the UNLOCK button.
The interior lamps
will come on for 40 seconds or until
the ignition is turned on. if you press the UNLOCK
button again within five seconds, all the remaining doors
(except the third door)
will unlock. Press the
LOCK button to lock
all the doors (except
the third door). The interior lamps will come on
for
two seconds as soon as all the doors are closed. If you
press the LOCK button twice the horn will chirp to
confirm that the doors have locked.
If you do not want the horn to chirp as a confirmation
that the doors have locked or unlocked, please consult
your dealer.
Matching Transmitter(s) To Your Vehicle
Each remote keyless entry transmitter is 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
remaining transmitters
with you when you go to your
dealer. When the dealer matches the replacement
t~-ansmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter

four transmitters
matched to
it.

Synchronization
Synchronization may be necessary d~te to the security
method used by this system. The transmitter does not
send the
same signal twice to the receiver. The receiver
will not respond to a signal it has been sent previously.
This prevents anyone from recording and playing back
the signal
from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and simultaneously press and hold the
LOCK
and UNLOCK buttons on the transmitter for at least
five seconds. The door locks should cycle to confirm
synchronization.
If the locks do not cycle. see your
dealer for service.
Theft
Vehicle theft is big business, especially in scme cities.
Although your vehicle has
a number of theft-deterrent
features, we know that nothing we put on
it can make it
impossible to steal. However. there are ways you can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target forjoy riders
01- professional thieves -- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear
a tone reminding you to remove your key
from the ignition and take
it with you. Always do this.
Ycx~r steering wheel will be locked, and so will your
ignition.
If you have an automatic transmission, taking
your key
out also locks your transmission. And
remember
to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember
to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it's best to lock
it up and take your keys.
But what if you have to leave your ignition key? What if
you have to leave something valuable in your vehicle'?
Put your valuables in a storage area, like your
glove box.
Lock all the doors except the driver's.

Locking Rear Axle (If Equipped)
If you have this feature, your locking rear axle can give
you additional traction on snow, mud, ice, sand or
gravel. It works like a standard axle most of the time,
but when one
of the rear wheels has no traction and the
other does, this feature will allow
the wheel with
traction to move the vehicle.
