{Warning
When changing the battery, use
only a battery of the same type as
the original battery, or an
equivalent. Otherwise, there is a
risk of explosion.
Do not place the battery in direct
sunlight, or near a fire or other
sources of heat.
Be sure to install the battery with
the "+" and "-" sides correctly
oriented. Incorrect installation will
result in leakage of chemicals
from inside the battery or other
operational problems.
You and others could be seriously
injured.
The battery life varies depending on
how the remote control unit is used.
The battery has reached its end of
life when the remote control unit
works intermittently or does not
work at all. Replace the battery as
soon as this happens.
Getting In and Out of the
Vehicle
Carefully check that the area around
the vehicle is safe, hold the grip (1),
and place your foot on the step (2)
when getting in or out of the vehicle.
{Warning
When getting in or out of the
vehicle, make sure you use the
step and grips to support yourself (Continued)
Warning (Continued)
at 3 points. It is very dangerous to
stand on the tire or wheel when
getting in or out of the vehicle.
Furthermore, do not try to jump in
or out of the vehicle, as doing so
could cause unexpected
accidents or injuries.
Getting in or out of the vehicle
with oily or greasy hands or
shoes could cause you to slip.
Always thoroughly clean grease,
etc. from your hands and shoes
before getting in or out of the
vehicle.
Rain and snow can cause the
step to become very slippery.
Therefore, always remove snow
and ice from your shoes and the
step, and be careful not to slip
when getting in and out of the
vehicle.(Continued)

18 Keys, Doors, and Windows
Warning (Continued)
Exercise caution when opening or
closing doors, as strong winds or
steep slopes may cause doors to
open or close suddenly.
Do not hold parts other than the
grip when getting in or out of the
vehicle. Doing so may cause
damage to the vehicle or injuries
to yourself or others.
You and others could be seriously
injured.
Door Locks
{Warning
Be sure to do the following
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
(Continued)
Warning (Continued)
belts properly, locking the doors
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.
{Warning
To protect the child from the
danger of getting his/her hands
and head trapped, an adult must
open, close and lock the door for
the child.
Be careful that the child does not
interfere with the power window
switches and get his/her hands or
head trapped in the window.

28 Seats and Restraints
{Warning
Make sure not to hit passengers
or luggage when adjusting your
seat. You and others could be
seriously injured.
{Warning
When adjusting the seat, or when
getting up from the seat, do not
put your hand or other objects
under the seat or near moving
parts. Doing so could cause injury
or damage to objects.
Driver’s Seat
The driver's seat must be adjusted
so that when you sit well back in the
seat, you can fully press the pedals
without moving your back from the
seatback, and you can operate the
steering wheel easily and freely.
After making adjustments, check
that the seat is completely locked. Adjusting the seat for a correct
driving posture is a fundamental
part of safe driving.
Forward/backward Adjustment
While raising the unlock lever, move
the seat forward or backward.
Release the lever when the seat is
in the desired position. After making
adjustments, try to move the seat
back and forth to check that it is
fully locked.
Reclining Adjustment
{Warning
To reduce the risk of sliding under
the lap belt during a collision, an
occupied reclining seat should not
be reclined any more than
needed for comfort. The seatback
and seat belts provide best
restraint only when the rider is
sitting well back and straight up in
the seat. (The lap belt is designed
to spread the force of a collision
over the hipbone. If you are
reclined, the lap belt may slide
past your hips and apply restraint
forces directly to the abdomen.
Therefore, in the event of a
collision, the risk of personal
injury will increase with increasing
recline of the seatback). You and
others could be seriously injured.

48 Storage
Load Cargo Correctly
{Warning
Overloading can result in a crash
because it places too much strain
on the wheel studs with the result
that they break and the wheels
come off.
The weight of the payload must
be limited within the gross vehicle
weight (GVW) rating and(Continued)
Warning (Continued)
distributed over the front and rear
axles so as not to exceed the
axle capacities.
It is extremely dangerous to
overload the vehicle or to load the
vehicle with the cargo positioned
on one side. Load the vehicle
correctly, observing the maximum
loading capacity.
Incorrect loading can make the
cargo unstable. It can also cause
an overload condition confined to
a small area, resulting in damage
to the cargo bed and frame.
Overloading places undue strain
on vehicle parts. It can shorten
the vehicle's service life and
cause a crash. You and others
could be seriously injured.

operated irrespective of the position
of the engine control switch.
The individual turn signals do not
work when the hazard flasher is
turned on.

130 Driving and Operating
The careful attention you give your
vehicle, as far as maintenance is
concerned, will also help fuel
economy.
Protection of Engine against
Overcooling
Overcooling of the engine not only
accelerates wear of the vital engine
parts but also hurts fuel economy.
Distracted Driving
Do Not Use a Mobile Phone
While Driving
{Warning
Drivers should never use mobile
telephones or car phones in any
mode other than Hands Free
while driving. Doing so is
dangerous. Using a mobile
telephone while driving could
result in a crash because you
would not be paying full attention
to your surroundings. If you are(Continued)
Warning (Continued)
driving and you wish to use a
mobile telephone, first stop the
vehicle in a safe place.
You and others could be seriously
injured.

Warnings for Driving
{Warning
Concentrate on driving safely,
obeying all legally designated
speed limits, road signs and
traffic signals.
If you notice any abnormal noise,
abnormal smell or abnormal
vibration from any part of the
vehicle, immediately stop the
vehicle in a safe place and
perform checks.
(Continued)
Warning (Continued)
If a warning light comes on or a
buzzer sounds while you are
driving, immediately stop the
vehicle in a safe place and
perform checks.
Slow down sufficiently when
approaching a curve. Applying the
brakes or sharply turning the
steering wheel while turning the
curve could cause the cargo to
shift, the tires to slip and the
vehicle to tip onto its side.
Avoid scraping the tire sidewalls
against curbstones or driving over
dips and protrusions in the road
surface. You could damage the
tires, resulting in a blowout or
flat tire.
You and others could be seriously
injured.

Driving and Operating 131
Pulling Away After Stopping
and Parking
Before pulling away, check that
there are no children or obstructions
around the vehicle and confirm that
it is safe to pull away.
If you cannot see the area behind
your vehicle well enough to confirm
it is safe to back up, get out of the
vehicle and check behind it.
Make it a habit to look around and
confirm that it is safe to pull away
after a temporary stop (at traffic
lights, for example).
If the Windshield Fogs Up
Use the heater to blow hot air on the
windshield or dehumidify the cabin
using the air conditioner and place
the outlet selector knob in the
5or
4position.
Place the air selector lever in the
outside air position.
Nighttime Visibility
If there is an old film on the
windshield, the lights of oncoming
traffic will be reflected in many directions, making it hard for you to
see ahead. Use glass cleaner to
clean the glass and the wiper
blades.
Worn wiper blades cannot wipe the
windshield clean and thus cannot
maintain visibility. When the wiper
blades become worn, replace them
with new ones.
Do Not Attach Accessories to
the Windshield or Windows
{Warning
Do not attach ornaments, films or
other accessories to the
windshield or windows. They
would impair visibility. Also, any
plastic suction cups used to
attach accessories could cause a
fire or a crash by acting as
lenses.
You and others could be seriously
injured.
Never Stop the Engine While
Driving
{Warning
Do not move the engine control
switch away from the "ON"
position while the vehicle is being
driven.
If the engine stops while the
vehicle is moving, the brake
booster does not work, and the
brakes would not work properly.
The engine could also be
damaged.
Stopping the engine while driving
would be extremely dangerous
because the power steering
would stop working, making the
steering wheel extremely hard
to turn.
Stopping the engine while driving
would be extremely dangerous
because the warning lights,
