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
ªChildren.º 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 so you can sit up straight.
To see how, see ªSeatsº 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.

Power Windows (If Equipped)
If your vehicle is equipped
with power windows, the
controls are located on each
of the side doors in the front
and rear.
The driver's door has a switch for the passenger window
as well. Your power windows will work when the
ignition has been turned to ACCESSORY or RUN or
when Retained Accessory Power (RAP) is present.
See ªRetained Accessory Powerº in the Index.
Press the rear of the switch with the power window
symbol on it to lower or raise the window.
The driver's window also has an express down feature
that allows the window to be lowered without holding
the switch. Press and hold the rear of the window switch
for one second to activate the express down mode. The express down mode can be canceled at any time by
pressing the opposite side of the switch. To open the
window partway, lightly tap the switch until the window
is at the desired position.
If you have power windows on a Crew Cab, the driver's
door power window switch has a lockout feature. This
feature prevents the rear windows from operating except
from the driver's position when the driver's door button
labeled WINDOW LOCK is engaged. When the button
is not engaged, the rear power windows will operate.

2-6
Your vehicle has one
double
-sided key for the
ignition and all door locks.
Your vehicle may also have
a key that locks and unlocks
only the center floor
console (if equipped).
If you ever lose your keys, your dealer will be able to
assist you with obtaining replacements.
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 won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't 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.

2-7
There are several ways to lock and unlock your vehicle.
You can use the keyless entry system (if equipped).
You can also use your key.
To lock the door from the
inside, slide the lever
rearward. To unlock
the door, slide the
lever forward.
Power Door Locks (If Equipped)
If your vehicle has this
power door lock switch,
press the raised side of the
switch, marked ªLº on
either front door to lock
all the doors at once.
Press the recessed side of the switch marked ªUº to
unlock all the doors at once.

2-8
If your vehicle has this
power door lock switch,
press the bottom of the
switch on either front door
to lock all the doors at once.
Press the top of the switch to unlock all the doors
at once.
The power door locks will operate at any time without
the ignition being on.
The power door locks will also automatically lock when
the vehicle reaches 15 mph (24 km/h). To unlock the
doors, refer to the instructions listed previously. The
automatic locking feature can be disabled, if you prefer.
See ªProgrammable Automatic Door Locksº in the
following text.
Operating the power locks may interact with the
theft
-deterrent system (if equipped). See ªContent
Theft
-Deterrentº in the Index.
Programmable Automatic Door Locks
Your vehicle is equipped with an auto lock/unlock feature
which enables you to program your power door locks.
Your vehicle left the factory programmed to have the
automatic lock feature lock all the doors when the
vehicle speed is greater than 15 mph (24 km/h) for two
seconds, and then unlock all the doors once the key is
removed from the ignition. The following instructions
detail how to program your door locks.
To enter the program mode you need to do the following:
1. Beginning with the ignition in OFF, pull back on the
turn signal/multifunction lever all the way toward
you and hold it while you perform the next step.
2. Turn your key to ON and OFF twice. Then, with the
key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock switch
lock and unlock.
3. You are now ready to program the automatic door
locks. Select one of the following four programming
options and follow the instructions. You will have
ten seconds to begin programming. If you exceed the
ten second limit, the locks will automatically lock and
unlock to indicate you have left the program mode.
