break the next time the headlamps are operated.
Install the new bulb(s) in reverse order.

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.

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.
