2. Remove the four screws from the
top and bottom front of the
headlamp assembly.
3. Press the retaining clip at the top
of the headlamp assembly while
pulling the assembly straight out.
If removing the lamp is difficult,
removing the four screws along
the top of the grill will help
provide more clearance.
4. Disconnect the electrical
connector by squeezing the release
tab and pushing the connector
forward and then pulling it
rearward.
5. Remove the bulb assembly by
turning it counterclockwise and
pulling it straight out.
Handle a halogen headlamp bulb carefully and keep out of
children’s reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil from your hand could cause the bulb to
break the next time the headlamps are operated.
Install the new bulb(s) in reverse order.

will not automatically set the lock
for both doors.
•Move lock control up to engage
the childproof lock.
•Move lock control down to

SAFETY RESTRAINTS
Safety restraints precautions
Always drive and ride with your seatback upright and the lap
belt snug and low across the hips.
To reduce the risk of injury, make sure children sit in the back
seat where they can be properly restrained.
Never let a passenger hold a child on his or her lap while the
vehicle is moving. The passenger cannot protect the child from
injury in a collision.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag
supplemental restraint system (SRS) is provided.

2. To unfasten, push the release
button and remove the tongue from
the buckle.
The front outboard and rear outboard safety restraints in the vehicle are
combination lap and shoulder belts. The front outboard passenger and
rear seat outboard safety belts have two types of locking modes
described below:
Vehicle sensitive mode
This is the normal retractor mode, which allows free shoulder belt length
adjustment to your movements and locking in response to vehicle
movement. For example, if the driver brakes suddenly or turns a corner
sharply, or the vehicle receives an impact of approximately 5 mph
(8 km/h) or more, the combination safety belts will lock to help reduce
forward movement of the driver and passengers.
On SuperCab and Crew Cab models, the front seat belt system can also
be made to lock manually by quickly pulling on the shoulder belt.
Rear seat belts (if equipped) cannot be made to lock up by pulling
quickly on the belt.
Automatic locking mode
When to use the automatic locking mode
In this mode, the shoulder belt is automatically pre-locked. The belt will
still retract to remove any slack in the shoulder belt. The automatic
locking mode is not available on the driver safety belt.
This mode should be usedany timea child safety seat is installed in a
passenger front or outboard rear seating position (if equipped). Children
12 years old and under should be properly restrained in the rear seat
whenever possible. Refer toSafety restraints for childrenorSafety
seats for childrenlater in this chapter.

How to use the automatic locking mode
•Buckle the combination lap and
shoulder belt.
•Grasp the shoulder portion and
pull downward until the entire
belt is pulled out.
•Allow the belt to retract. As the belt retracts, you will hear a clicking
sound. This indicates the safety belt is now in the automatic locking
mode.
How to disengage the automatic locking mode
Disconnect the combination lap/shoulder belt and allow it to retract
completely to disengage the automatic locking mode and activate the
vehicle sensitive (emergency) locking mode.
After any vehicle collision, the front passenger and rear outboard
seat belt systems must be checked by your authorized dealer to
verify that the “automatic locking retractor” feature for child seats is
still functioning properly. In addition, all seat belts should be checked
for proper function.
