damage to the vehicle or injuries
to yourself or others.
You and others could be seriously
injured.

whenever you leave the vehicle:1. Fully engage the parkingbrake.
2. Stop the engine.
3. Lock the doors. (Continued)
Warning (Continued)
When you close the door after
sitting behind the wheel, check
that the door is fully closed.
Driving with any door ajar is very
dangerous.
Before opening the door when
climbing into or out of the cab,
carefully check all areas around
the vehicle for safety, especially
the area at the rear of the vehicle.
If you suddenly open a door
without checking the surrounding
area, the door could be hit by a
vehicle behind you or a
pedestrian.
Never leave the key in the
vehicle.
Tilt the cab only after fully closing
the doors.
To help reduce the risk of
personal injury in an accident,
always lock the doors when
driving. Along with using the seat

helps prevent people from being
thrown from the vehicle. It also
helps prevent unintended opening
of the doors and helps keep out
intruders.
You and others could be seriously
injured.

Seat Position
{Warning
Use caution when adjusting the
seat, as failure to do so could
cause injury. You and others
could be seriously injured.
{Warning
Never allow children to adjust
their seats themselves; an adult
should adjust the seat for
occupants who are children. You
and others could be seriously
injured.
{Warning
Adjust the seat only before you
start driving. Adjusting the seat
while the vehicle is in motion
must be avoided not only
because the unlocked seat will
move back and forth unstably,
preventing you from taking the
correct position, but might also
cause you to lose control of the
vehicle, possibly resulting in an
accident. You and others could be
seriously injured.
{Warning
Try to move the seat without
unlatching it after making
adjustments to check that it is
completely locked. A loosely
locked seat may move
unexpectedly and your position
might then become unstable; this
could lead to an accident. Take
the vehicle to your dealer for

When the passenger's seat belt is
fully taken up (or not pulled out),
check that the stopper is holding the
belt in a fully taut state.
Emergency Locking Retractor
(ELR) Function
The three-point seat belts are
provided with an Emergency
Locking Retractor (ELR) function.
The ELR normally allows the seat
belt to move in and out freely as the
occupant moves. However, it locks
the seat belt to restrain the
occupant when a forward force
resulting from a collision or sudden
stop acts on the occupant.
The ELR also locks the seat belt
when the belt is pulled out quickly.
If this happens, allow it to retract
once and then pull it out slowly.Seat Belt Use During
Pregnancy
{Warning
Unless the seat belt is correctly
worn, it may dig into the abdomen
in the event of hard braking or a
collision, harming not only the
expectant mother but also the
unborn child, putting them both in
danger of serious injuries or
death.
An expectant mother or a person
who is ill riding in the vehicle must
also wear a seat belt. In light of the
risk that the seat belt will apply
pressure to the abdomen, chest and
shoulders in the event of a collision,
however, an expectant mother or
person who is ill should get advice
from a physician beforehand.
.An expectant mother should use
a three-point seat belt.
. An expectant mother should
position the lap belt snugly as
low as possible on the hips (not
across the abdomen). Also, she
should fasten the shoulder belt
so it rests on her chest, not on
her abdomen.

52 Seats and Restraints
Warning (Continued)
shoulder belt can be worn, a
seating position with a shoulder
belt should be chosen whenever
possible.
Any unrestrained child could be
injured by striking the vehicle's
interior or by ejection from the
vehicle during an accident or
driving maneuver. Never allow a
child to be held by another
occupant instead of being
properly restrained. If not properly
restrained, the child could strike
the vehicle interior or be crushed
by the person holding the child,
or by other occupants.
Be sure to follow all installation and
use instructions that come with any
child restraint system.
Child restraint systems are designed
to be secured in vehicle seats either
by the lap belt, or the lap portion of
the lap-shoulder belt at that seating
position. The child must also be
secured within the restraint by the means provided by the child
restraint manufacturer. If the child or
the child restraint is not properly
secured, the child risks personal
injury in the event of a collision.
Using a Lap Belt That Has No
Retractor
When securing a child restraint with
the center seat lap belt, pull the
excess webbing through the belt's
adjustment feature, then take these
steps:
.
Once installed, push and pull the
child restraint in all directions to
be sure it is secure. If it comes
loose, flip the end of the belt
with the adjustment feature over
before rebuckling.
. If the child restraint is still not
secure, use the outboard seating
position in the vehicle and
contact your dealer and the child
restraint manufacturer for help.
. Secure the child in the restraint
in accordance with the child
restraint manufacturer's
instructions.
Installation on Outboard Seat
A seat belt locking clip is required
for installation of a child restraint
system on the outboard seat of this
vehicle. A locking clip may usually
be obtained where child restraints
are sold, or by contacting your
dealer for assistance. Make sure the
locking clip is identical to the one
shown on this page. Until you have
the clip, use the child restraint
system only in the center seat.

{Warning
To help avoid personal injury or
death during a collision or sudden
maneuver, always thread both the
lap and shoulder belt through the
locking clip when securing a child
restraint on the outboard seat.
If the clip is not used or installed
properly, the child restraint may
move or tip over when your
vehicle turns or stops abruptly.
Secure the child restraint with the
lap belt portion (1) of the seat belt in
accordance with the restraintmanufacturer's instructions. Then
thread both the lap (1) and shoulder
belt (2) portions through the locking
clip. Push and pull the child restraint
in all directions to be sure it is
secure.

{Warning
We do not recommend using a
child restraint that requires the
use of a top strap. There is no
appropriate place to attach a top
strap anchor behind the seat in
this vehicle.
