Center Seat
You can tip the seatback forward if
you pull forward the lever at the side
of the seatback. Normally, you
should keep the seatback in the
raised position.
See Seat Position 038.
Seat Belts
Refer to the following sections for
important information on how to use
seat belts properly:
.
Seat Belts 043

Mirror Adjustment
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.

the two keys provided as a
spare (2). Record the key code
numbers. Both sides of the key are identical,
so you can insert the key in the
engine control switch without
worrying about which way you
insert it.
The key code is indicated on a
separate metal plate (3) in order to
prevent it from being acquired by an

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.

{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.

142 Driving and Operating
When the Silencer and
Exhaust Pipe are Hot
{Warning
When the engine is running and
immediately after vehicle
operation, the DPF, silencer, and
exhaust pipe are extremely hot.
Be careful not to inadvertently
touch them when working near
them (for example, tilting the cab
or operating an attachment). You
and others could be seriously
injured.
Recommendations for Driving
in Hot Regions
The engine is more likely to
overheat in an environment where
the ambient temperature is high. To
prevent the engine from
overheating, pay attention to the
following points:
.If the engine does not contain
the appropriate concentration of
engine coolant, overheating is
likely to occur. Refer to
Engine Coolant 0253.
. Do not put well water, river water
or other hard water in the engine
cooling system. It would hasten
the formation of rust and scale.
. If foreign matter (insects, mud,
etc.) gets stuck in the radiator's
air passages, the cooling
system's performance will
deteriorate. Check the air
passages for clogging, and
remove any foreign matter using
water under low pressure.
Refer to Exterior Care 0317.
When Turning, the Rear
Wheels will Follow Tighter
Curves than the Front Wheels
Use the mirrors to confirm safety.
Sidewinds
If the vehicle catches a sidewind
and drifts sideways, firmly grip the
steering wheel, decelerate to a
speed that allows you to stay
completely in control, and make a directional correction. The vehicle
may catch strong sidewinds in the
following situations:
.
Emerging from a tunnel
. Driving over a bridge
. Driving on an embankment
. Driving through a cutting
. Being overtaken by a large truck
or bus
. Overtaking a large truck or bus
Flat Tire
If a blowout or flat tire occurs while
you are driving, calmly grip the
steering wheel and gradually apply
the brakes to decelerate. (Hard
braking would be dangerous
because it could cause the steering
wheel to be pulled to one side.)
Stop the vehicle in a safe place, and
change the tire.
Hard Bump Under Vehicle
If the underside of the vehicle
receives a hard bump, stop in a safe
place where the vehicle will not
obstruct traffic and check for brake

150 Driving and Operating
road to make a "mirrored surface"—
and slow down when there is any
doubt.
There is a risk of hydroplaning,
particularly where water tends to
collect on the road surface. Drive at
speeds that allow you to stay in
complete control.
If you cannot avoid driving on a
flooded road, first check the depth
of the water and then drive through
the water at a slow, constant speed.
There is a risk that water will get
into the engine's cylinders and
cause engine damage (water
hammering). Keep your speed
down, and drive with great care.
Hydroplaning :If a vehicle is driven
at high speed on a road that is
covered with water, a layer of water
can form between the tires and road
surface, causing the tires to lose
their grip and slide across the water.
This phenomenon is called
hydroplaning. It is dangerous
because it makes the steering
wheel and brakes useless.
Refer to Wheels and Tires 0295.Hill and Mountain Roads
Narrow or Congested Roads
When passing or overtaking a
vehicle on a narrow mountain road
or on a narrow or congested urban
road, pay careful attention to
obstacles on either side and to the
condition of the shoulder of
the road.
When turning, the rear wheels will
follow tighter curves than the front
wheels. Use the mirrors to confirm
safety.
Driving Uphill or Downhill
Downshifts are performed for two
main purposes:
.
For engine braking on a steep
and/or long downward slope
. For responsiveness and
economy on an uphill slope
Drive at a speed that does not
cause the tachometer needle to
enter the red zone.
Uphill
Shift down well ahead of time in
order to avoid a heavy load to the
engine.
Downhill
.
Be careful not to drive too fast
on a downhill road.
. Use the same gear(s) that you
used to drive up the hill. Also,
use the exhaust brake in order
to avoid going too fast.
. Do not let the engine overrun.
