{Warning
If you are traveling with a child,
do not leave the child alone in the
vehicle. If the child touches the
controls or equipment, an
accident could occur. (For
example, the vehicle could move
or a fire could start.) Also, the cab
inside could become dangerously
hot in hot weather.
{Warning
Before closing the windows, make
sure that there is no risk of a
hand, head, or anything else
being trapped in the moving
window.
You and others could be seriously
injured.
{Warning
Regardless of whether the vehicle
is moving or stationary, you must
never allow a child to put his/her
head, hands, or other body part
out of the window. Allowing such
behavior would be dangerous
because the child could hit an
obstacle.
You and others could be seriously
injured.
The power windows operate only
when the engine control switch is in
the ON position. Open each door
window by pressing the power
window switch; close each one by
raising the switch.

Seats and Restraints 43
Seat Belts
The protection provided by seat
belts might be significantly reduced
if they are not fastened properly; in
certain cases, improperly fastened
seat belts can even play a role in
causing injury to the wearer. Seat
belts must be worn not only by the
driver but also by the passenger(s)
before the vehicle starts moving.
You should be fully acquainted with
the proper use of seat belts and
important points to be respected as
described in the following pages.Familiarizing yourself with the
correct use of seat belts is essential
for your safety.
{Warning
To help reduce the risk of
personal injury in collisions or
sudden maneuvers, use the seat
belts following these instructions
on their proper use, maintenance,
and use with child restraint
systems.
Seat belts must always be
fastened BEFORE starting to
drive.
Seat belts provide full protection
only when the driver and
passenger(s) fasten them while
sitting upright and fully back on
the seat.
Wearing a seat belt with the
seatback excessively reclined
could be very dangerous in a
collision or sudden stop since the
occupant may slide under the belt

Warning (Continued)
and be seriously injured. Seat
belts work best only when the
occupant is sitting well back and
straight up in the seat.
Be sure to insert the latch plate
into the buckle until a click is
heard. An incompletely inserted
latch plate is dangerous in the
event of a collision or
sudden stop.
Do not run the seat belt over your
face, chin or neck.
Wear the seat belt as low as
possible around the hips, not
around the waist. A seat belt
running over the waist would
press the abdomen with a strong
force and could increase the
likelihood of injuries in a collision
or sudden stop.
Do not use a seat belt for a small
child if the belt is on or very close
to the child's neck or chin. Also,(Continued)

when the engine control switch is
turned to the ON position, and then
should go out after the engine is
started.
Brake System Warning Light
If the light remains on after engine
start up or comes on during
operation of the vehicle, it means
that there is something wrong with
part of the brake system.The brake system warning light
comes on while the engine is
running (after startup) in the
following situations:
.
Drop in the level of brake fluid
(due to brake lining wear or fluid
leakage).
. Abnormality in the charging
system (such as an alternator
malfunction or loose or split
fan belt).
. Abnormality in the anti-lock
brake system (ABS) and
Electronic Braking force
Distribution (EBD) functions.
(The ABS warning light and
brake system warning light will
illuminate at the same time.) See
Antilock Brake System (ABS)
Warning Light 077.
To serve as a reminder, the light
should stay on when the parking
brake is not fully released, and the
engine control switch is on. Have
the system repaired if the light does
not come on when it should. If this
warning light does not go away,
brake inspection and maintenance
should be performed.
Check and Corrective Action
1. Check to see that the parking brake has been fully released.
If it has, check the following:
2. Turn on the exhaust brake to help slow the vehicle.
3. Pull off the road and stop carefully. Remember that
stopping distances may be
longer, the pedal may be
harder to push, and the pedal
may go down farther than
normal.
4. Check the brake fluid reservoir on the left side of the
instrument panel. If low, add
fluid as needed.
5. If the brake fluid is not low: Try out the brakes by starting and
stopping on the shoulder of the
road, then either drive
cautiously at a safe speed to
the nearest dealer for repair,
if you judge driving to be safe;
or have the vehicle towed to
the nearest dealer for repair.

system designed so that one part
will provide some braking if there is
a loss of hydraulic pressure in the
other part of the system.
{Warning
If this warning light comes on
while the engine is running,
immediately stop the vehicle at a
safe place well clear of traffic and
