262 Vehicle Care
Power Steering Fluid
The power steering fluid level must
be checked and it must be changed
according to the Maintenance
Schedule. SeeMaintenance
Schedule 0327.
When replenishing power steering
fluid or flushing the power steering
system, always use ATF
(Dexron
®-VI). Failure to use the
proper fluid may damage the power
steering system seals and hoses,
leading to fluid leakage.
Checking the Power Steering
Fluid Level
The fluid level is correct if it is
between the “MAX”and“MIN” lines
on the power steering fluid tank.
If the level is lower that the “MIN”
line, add fluid up to the “MAX”line.
The reserve tank is located at the
rear of the engine compartment on
the right. When you have finished
checking the fluid level, securely
reinstall the cap and cover.
{Warning
Before adding fluid, clean the
area around the cap and pour
fluid from a clean jug or filler.
Foreign matter getting in the tank
may cause power steering system
failure.
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

320 Vehicle Care
The application of wax to rubber
component surfaces can result in
permanent whitening.
Wax must not be applied to the
windshield. Failure to observe this
precaution can result in irregular
reflection of light, impairing
your view.
Protecting Exterior Bright Metal
Parts
Bright metal parts should be
cleaned regularly to keep their
luster. Washing with water is all that
is usually needed.
Use special care with aluminum
trim. To avoid damaging protective
trim, never use auto or chrome
polish, steam or caustic soap to
clean aluminum. A coating of wax,
rubbed to a high polish, is
recommended for all bright metal
parts.
Weatherstrip Lubrication
All weatherstrips should be
periodically lubricated (minimum of
every 6 months) with a weatherstrip
lubricant. A thin film of weatherstriplubricant should be applied using a
clean cloth. Weatherstrip lubricant
application will lengthen
weatherstrip life, help sealing, and
assist in eliminating squeaks.
Windshield Care
Wax must not be applied to the
windshield. A layer of wax can
impair your view in rainy weather
and can also lead to rough
movements of the windshield wiper.
If engine oil or grease comes into
contact with the windshield, staining
or discoloration may result. It must
be immediately cleaned away.
If not fully cleaned by the windshield
wipers, the windshield should be
cleaned using glass cleaner. If your
windshield is not clear after using
the windshield washer, or if the
wiper blade chatters when running,
wax or other material may be on the
blade or windshield.
The windshield wipers on your truck
can be pulled out from the
windshield to provide easier access
for cleaning.
Clean the outside of the windshield
with a non-abrasive cleaner. Your
windshield is clean if beads do not
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 roof marker
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,

one side, unusual sounds when
braking, increased brake pedal
travel or harder pedal. The front and
rear brakes are attached to an auto
adjuster mechanism. If there are no
defects, as the pedal travel is
properly maintained, adjustments
are not necessary. Check regularly
that the brake fluid reservoir
(left-hand side of the instrument
panel) or HBB reservoir (5500HD,
5500XD models: left side behind the
cab) is properly filled and check for
fluid leaks. Any of these conditions
could indicate the need for brake
system inspection and/or service.
G: Exhaust System :Be alert for
any changes in the sound of the
exhaust system or any smell of
fumes. These are signs the system
may be leaking. Have it checked
and/or repaired at once. (Refer to
"Engine Exhaust Emissions Caution
(Carbon Monoxide)" under Engine
Exhaust 0177).

Washers : Check operation and
condition of the wiper blades. Check
the flow of the washer spray. I: Defroster :
Turn the outlet
selector knob to "Defroster" and the
fan speed control knob to the fully
clockwise position. Then check the
airflow from the ducts at the inside
base of the windshield.

broken, scratched, dirty or damaged
glass, mirrors, lamps or reflectors
that could reduce the view or
visibility, or cause injury. Replace,
clean or repair promptly.

close, latch and lock tightly. Check
for broken, damaged or missing
parts that might prevent tight
latching.
