{Warning
If the key is unintentionally rotated while
the vehicle is running, the ignition could
be moved out of the RUN position. This
could be caused by heavy items hanging
from the key ring, or by large or long
items attached to the key ring that could
be contacted by the driver or steering
wheel. If the ignition moves out of the
RUN position, the engine will shut off,
braking and steering power assist may be
impacted, and airbags may not deploy.

Warning (Continued)
Remote Keyless Entry (RKE) transmitter,
if equipped, are connected to the
provided key rings.
The ignition key and key rings, and RKE
transmitter, if equipped, are designed to
work together as a system to reduce the
risk of unintentionally moving the key out
of the RUN position. The ignition key has a
small hole to allow attachment of the
provided key ring. It is important that any
replacement ignition keys have a small hole.
See your dealer if a replacement key is
required.
The combination and size of the rings that
came with your keys were specifically
selected for your vehicle. The rings are
connected to the key like two links of a
chain to reduce the risk of unintentionally
moving the key out of the RUN position. Do
not add any additional items to the ring
attached to the ignition key. Attach
additional items only to the second ring,
and limit added items to a few essential
keys or small, light items no larger than an
RKE transmitter.

Getting In and Out of the Vehicle
1. Grip
2. Step
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 at 3 points. It is very
dangerous to stand on the tire or wheel
when getting in or out of the vehicle.
(Continued)
Warning (Continued)
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.
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 parking brake.
2. Shut down the engine.
3. Lock the doors.
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.

Warning (Continued)
To help reduce the risk of personal injury
in an accident, always lock the doors
when driving. Along with using the seat
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. While a child is
in the cab, be sure to control the power
windows using the power window
switches beside the driver's seat.
You and others could be seriously injured.

feature. When the doors are locked, the
inside handles will not open them. This is to
prevent accidental opening of the doors.

Vehicle Security
Guard Against Theft
Your new vehicle has many features to help
prevent theft of the vehicle, its equipment
and contents. But these anti-theft features
depend upon you to work.

The time to be most on guard is when
leaving the vehicle:
.Park in a lighted spot when you can.
.Turn the engine control switch to "LOCK"
and remove the key. This locks the switch
and the steering controls. The selector
lever is not locked.

Exterior Mirrors
Mirrors
{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.
(Continued)
Warning (Continued)
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.
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.
Sit in the correct driving position with the
seat adjusted properly. Then, check each
mirror to ensure that a proper view of the
rear and sides of the vehicle are provided.
Make adjustments and clean mirrors if
necessary.

of the outside rearview mirror by hand if
your vehicle is equipped with a remote
mirror control switch. Otherwise, the
mirror motor may sustain damage.
If equipped, the remote mirror control
switch is used to adjust the outside rearview
mirrors remotely and is active only when
the engine control switch is in the "ACC" or
"ON" position.

Heated Mirrors
If the outside 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

{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.
Window Switches on Driver’s Door
The power window switch on the driver’s
door can operate both driver’s (2) and
passenger’s (1) power windows.
To Open the Driver’s Window
Lightly pressing the driver-side window
switch will lower the driver’s window until
the switch is released (manual mode
operation). When the switch is firmly
pressed, the window will lower completely
without the need to press the switch
continuously (automatic mode operation).
If you want to stop the automatic
movement of the window before it lowers
completely, raise the switch lightly.
