{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.

O:Use this position to prevent
dusty or otherwise contaminated
outside air from entering the cab,
such as in a tunnel or in congested

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.
