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.
. Keep items that may appear to
be of value out of sight and
locked up when possible.
. Fully close all windows and lock
all doors.
Exterior Mirrors
Mirrors
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.
Outside Rearview Mirrors
After properly adjusting your seat for
proper driving position, adjust the
mirrors so that they provide
adequate views for checking the
rear and the sides of the vehicle.
Adjust the outside rearview mirrors
by hand before vehicle operation.
This helps you determine the
location of objects seen in the
mirror. If the outside mirror fogs up,
warm up the outside rearview
mirror's face to defog.
See Heated Mirrors 040.

{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.
Rearview 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 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 stopped. Due to high
power consumption, the battery can
be discharged.
Turn off the switch as soon as
defogging is complete.

Climate Controls 127
O:Use this position to prevent
dusty or otherwise contaminated
outside air from entering the cab,
such as in a tunnel or in congested
traffic.
Extended use of the inside air
recirculation position causes the
windshield and windows to fog up
easily, making visibility poor. For
good ventilation, switch to outside
air as soon as possible.
Temperature Control Knob : Use
this knob to select the preferred cab
interior temperature. Turn the knob
counterclockwise to lower the outlet
air temperature and clockwise to
raise it.
Fan Speed Control Knob : The fan
speed can be adjusted to any of the
four speeds available.
Air Conditioning (A/C) Switch :
Press this switch to use the air
conditioning system. The indicator
light inside the switch will come on
to show that the air conditioning
system is in operation. The air
conditioning system can also be
used for dehumidifying while the heater is being used. To turn off the
air conditioning, push this switch in
again.
When the defrost mode is selected,
the air conditioner compressor will
be on.
Even if the A/C switch is turned on,
the air conditioning system will not
operate when the fan speed control
knob is placed in the stop position.
Make sure that the fan speed
control knob is in a position other
than the stop position.
Even in seasons when the air
conditioning system is not used,
occasionally operate the system for
a few minutes with the engine
running at a low speed in order to
keep the system's components
lubricated.
Ventilation
Outside Air Ventilation :
Press the
A/C switch to the off position. Turn
the outlet selector knob to the
preferred position. Move the air
selector lever to the
Pposition. Set the temperature control knob to
the desired position. Adjust the fan
speed control knob to the preferred
speed.
How to Use the Heater
Normal Heating :
Set the outlet
selector knob to the
6or-
position. Use the-position for
warming your feet while defogging
the windshield.
Set the air selector lever to the
P
position. Adjust the temperature
control knob and the fan speed
control knob to the desired
positions.
To dehumidify the cab interior while
heating, press the A/C switch to the
on position.
As the heater uses the heat from
the engine coolant, its heating effect
is weak when the engine coolant
temperature is low.
Maximum Heating : Turn the outlet
selector knob to the

position, and turn the temperature
control knob fully towards the high
temperature direction.
Set the fan speed control knob to
the maximum speed position.
Bi-Level Heating :Set the outlet
selector knob to the
)position. Set
the air selector lever to the
P
position. Set the temperature control
knob to the middle position.
Adjust the fan speed control knob
as desired. The air from the floor
outlets is warmer than the air from
the upper outlets in this position.
However, when the temperature
control knob is moved to either the
full hot or the full cold position, the
air from the floor outlets and the air
from the upper outlets will be the
same temperature. This position can
give cool upper level air and warm
floor level air when the temperature
control is adjusted in between cold
and hot. This is useful in cool
weather with bright sunlight
conditions. Defogging and Defrosting the
Windshield
Defogging :
Set the outlet selector
knob to the
1position. Set the air
selector lever to the

defogging in the summer months,
set the temperature control knob to
any desired position.
Set the fan speed control knob to
any speed position, except the off
position. The A/C compressor
automatically operates when the
1
position is selected. Defogging is
performed very effectively with the
dehumidifying effect.
Defrosting : Set the outlet selector
knob to the
1position. Set the air
selector lever to the
Oposition.
Turn the temperature control knob
fully towards the high-temperature
direction. Set the fan speed control
knob to the maximum speed
position. After defrosting, be certain to return
the air selector lever to the
P
position. Failure to do so will cause
the windshield to fog up, impeding
forward visibility.

134 Driving and Operating
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.
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 other accident by acting as
lenses.
You and others could be seriously
injured.

Bulb Wattage
{Warning
Using bulbs with a wattage other
than that specified could cause
the bulb or the wiring to become
hot. This could result in the
warping of the lens and case, and
it could also lead to the outbreak
of fire.
Bulbs are hot immediately after
they go out. When replacing the
bulbs, avoid being burned by
making sure they are fully cooled.
Never drive the vehicle with the
bulbs not working. This could
result in an accident.
You and others could be seriously
injured.
When one bulb of a pair of lamps,
such as a headlamp blows out, the
other bulb is approaching the end of
its useful life. We recommend that
both be changed at the same time. For the lamps (lighting equipment)
such as headlamps, inside of the
lens can mist up momentarily when
driving in the rain or during the car
wash. Also, the temperature
difference between inside and
outside of the lamps can sometimes
cause the water condensation
inside the lens. This is not abnormal
because this is the same
phenomenon as the windshield or
door glass fogs up when it rains. If it
is demisted minutes after the lamp
is turned on, things are normal.
