{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 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

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

{Warning
Before driving, be sure to adjust
the seat and mirrors to positions
that give you a correct driving
posture.
Do not adjust the outside mirrors
while operating the vehicle.
Adjust the mirrors when the
vehicle is stationary, not while the
vehicle is in motion.
When checking the rear of the
vehicle with mirrors, be careful
that this does not distract your
attention from the traffic ahead.
Outside mirrors may make the
vehicle behind you appear farther
away than it really is. Use these
mirrors very carefully until you are
able to correctly determine
distances from the images.(Continued)
Warning (Continued)
Keep the mirrors in mind when
passing another vehicle on a
narrow road, moving the vehicle
into a garage, or driving near
pedestrians.
Do not drive with the mirrors
folded.
You and others could be seriously
injured.
Heated Mirrors
If the outside rearview mirrors fog
up, press the outside rearview
mirror heater switch to defog them.
When the switch is pressed the
indicating light will illuminate. If the
switch is pressed once again, it will
switch to“OFF,”and the operation
indicating light will go out.
Do not use this switch while the
engine is shut down. Due to high
power consumption, the battery can
be discharged.
Turn off the switch as soon as
defogging is complete.

{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

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.

{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
service if you find that your seat
adjusters do not latch. In addition,
the seat belt will not operate
properly if the seatback is not
completely locked. You and
others could be seriously injured.
{Warning
Driving with the seat excessively
reclined could be very dangerous
in the event of a collision or
sudden stop. Raise the seatback,
and apply the seat belt correctly
while sitting straight in the seat.
You and others could be seriously
injured.
{Warning
Do not place a cushion or similar
object between your back and the
seatback. Doing so not only
affects the stability of your driving
position but also prevents the
seat belt from working effectively
in the event of a collision. You
and others could be seriously
injured.
{Warning
Do not place any objects under
the seat. If there are any objects
under the seat, the seat could be
locked in an improper position.
You and others could be seriously
injured.
{Warning
Before making adjustments,
check that the seat rails are free
of anything that could obstruct the
locking of the seat. Be careful that
your hand or foot does not
become trapped in the seat or
rails when adjusting the seat. You
and others could be seriously
injured.
{Warning
When adjusting the seat, be
careful that the seat does not hit
passengers or objects. Doing so
could cause injury to passengers,
or damage objects. You and
others could be seriously injured.
