66 Instruments and Controls
Windshield Wiper/Washer
To use the windshield wiper and
washer switches, the engine control
switch must be in the ON position.
The windshield wiper switch has the
following positions, which
correspond to the states of the
wiper.
9:Stopped.
3:Intermittent, light rain.
Low Speed : Low speed,
moderate rain.
High Speed : High speed,
heavy rain. If the wiper frequently stops during
operation, contact your nearest
Dealer.
Before operating the wiper, ensure
that the wiper rubber is not stuck on
to the windshield. If the wiper rubber
is stuck to the windshield and you
still operate the wiper, the wiper
may break or the wiper motor
may fail.
Clear ice or packed snow from the
wiper blades before using the
wipers. Carefully loosen or thaw
wipers that are frozen to the
windshield.
Do not operate the wiper on a dry
windshield surface. Otherwise, the
windshield surface may sustain
damage.
Windshield Washer
{Warning
At extremely low temperatures,
washer fluid may freeze on the
windshield after being sprayed,
obstructing your forward view. In

such a case, warm up the
windshield before using the
windshield washer.
Windshield washer fluid is sprayed
over the windshield when this switch
is pressed. At the same time, the
windshield wiper operates.
To spray washer fluid on the
windshield, push the button on the
end of the combination switch lever.
The spray will continue as long as
you hold in the button.

When Ice Prevents You from
Putting Your Key in the Door
or Opening the Door
If you try to force the key into the
door, you could bend it. And if you
try to pull the door open with undue
force, the rubber seal around the
door could come unstuck or become
damaged. Use warm water to melt
the ice, then quickly wipe it away
and open the door.
If the wipers, electric door mirrors,
or power windows freeze up, also
use warm water to melt the ice and
then operate the system. Otherwise,
you could damage the mechanism
and drain the battery. After that,
wipe the water away.
Before Driving in Cold Regions
Getting In and Out of the Vehicle
The step can get icy in cold regions.
Be careful not to slip when getting in
and out of the vehicle. Before Sitting in the Driver
’s Seat
Remove snow and ice from your
shoes when getting into the vehicle.
If you try to drive with snow on your
shoes, your shoes would slip on the
pedals and you would not be able to
press the pedals properly, meaning
that your driving would be
inconsistent. Also, the cabin could
become more humid, causing the
glass to fog up.
Check Fuel Level
Fuel consumption increases when
tire chains are used. Determine how
much fuel you need to reach your
destination and fill up the tank in
advance. Refer to Fuel for Diesel
Engines 0206.
Removing Snow from Glass
and Underbody
Do not use a sharp implement to
remove snow. Sharp edges could
damage rubber parts.
To maintain an adequate field of
view, use a plastic scraper to
remove snow and frost from the
glass surfaces. By using a plastic
scraper, you can remove the snow and frost without scratching the
glass. At this time, check whether
the wiper blades are frozen onto the
glass.
Also, look under the vehicle and
remove any lumps of ice that are
stuck to the underbody. Be careful
not to damage components.
Driving on Snowy or Frozen
Roads
On slippery roads, never accelerate
rapidly, brake hard, decelerate
rapidly or make sharp turns of the
steering wheel.
There is a risk of reduced grip
between the tires and road surface
and of increased braking distances.
The danger of icy road surfaces is
particularly great on bridges, in
shady places and where there are
puddles.
Keep your speed down and be sure
to use tire chains or winter tires on
snowy or frozen road surfaces.
Use engine brakes together with the
foot brakes to decelerate. Using the
exhaust brake on a slippery road
surface could cause the tires to slip.

Warning (Continued)
Do not mix the recommended
power steering fluid with fluids of
other brands. Due to chemical
reactions, any mixture of
differently branded fluids may
cause failure of the system.
You and others could be seriously
injured.
Washer Fluid
Windshield Washer Fluid
The windshield washer is equipped
on the windshield wiper arm.
Check the level of fluid in the
windshield washer fluid tank. In
addition, spray windshield washer
fluid and operate the windshield
wipers to check for any areas not
properly wiped. At this time, also
check the spraying condition of the
windshield washer.Inspect the washer fluid level
regularly, especially during bad
weather conditions.
Use a high quality premixed solvent
available at most dealers or service
stations.
Avoid hard water when mixing
windshield washer solvents. Hard
water contaminants may plug
orifices in the washer system and
reduce performance.
Do not use radiator antifreeze in the
windshield washer; it could cause
cab paint damage.
In cold weather, warm the
windshield with the defrosters
before using the washer, to help
prevent icing that may block the
driver's vision.
Refilling Windshield Washer
Fluid
1. The windshield washer fluid
tank (1) is located under the
instrument panel on the
passenger side.
2. Open the cap (2) and fill the tank with windshield washer
fluid.
Upon factory shipment, new
vehicles contain only tap water in
the washer fluid tank. Adjust the
concentration of the fluid to suit your
own usage.

form when rinsing with water. Clean
the blade by wiping with a cloth
soaked in a solution of one-half
water and one-half methanol
alcohol. Then rinse the blade with
water.
The windshield wiper arms may be
swung out, away from the glass, to
provide easy access for cleaning.
Do not hang on to the roofmarker
lights while cleaning the windshield
or damage may occur (resulting in
possible water leakage).
External Diesel Engine
Cleaning
The engine does not need periodic
cleaning, nor is it recommended.
If you insist on cleaning the engine,
clean it only when it is cold, never
when it is warm or hot, and never
when the engine is running.
Spraying or pouring water or other
fluids on your engine when it is
warm or hot, or when it is running,
can cause serious damage to the
engine and its components,
particularly the fuel supply pump.
Handling the Radiator and
Charge Air Cooler
Cleaning the Radiator Core and
Charge Air Cooler Core
Cooling efficiency is compromised
when there is dirt or dust plugging
air passages in the radiator core
and charge air cooler core. This can
also cause corrosion of these cores.
Wash the radiator core with tap
water every 24 months.
Make sure to turn the engine off and
remove the key from the engine
control switch before cleaning
cores.The engine, exhaust pipe, and
radiator will be hot immediately after
the vehicle is driven. Be careful
around these parts to prevent burns.
Clean the engine when it is cold.
Do not clean the radiator, charge air
cooler and their surrounding areas
using water that is supplied under
high pressure. Doing so may cause
damage.
When cleaning the radiator core (1)
and charge air cooler core (2) , do
not crush or damage the fins (3).
The fins are very fragile so be
careful not to bend them out of
shape. If they become deformed,

These checks are in addition to, not
instead of, any legally required daily
inspections. See related topics
under "Maintenance Schedule",
especially if problems are found.
For safe and comfortable driving,
keep record of the distances driven
and the condition of the vehicle
during operation. Perform
inspections at appropriate intervals,
and perform maintenance in
accordance with the findings of the
inspections. If an inspection reveals
an abnormality or there was an
abnormality the previous time the
vehicle was driven, have the vehicle
repaired by the nearest dealer
before it is driven again.1. Components that showed abnormalities during the
