before applying the car wash and
wax solution.
• Do not wash the vehicle in direct
sunshine.
• Do not spray water directly into
the cab vents.
2. Using soapy water, wash the vehicle
with a clean soft cloth or a soft
brush made for automotive
cleaning.
• Use cool or warm water and a
mild, household type soap.
Strong industrial detergents and
cleaning agents are not
recommended.
• Do not use stiff brushes, paper
towels, steel wool, or abrasive
cleaning compounds because
they will scratch painted, plated,
and polished metal surfaces.
3. Rinse surfaces frequently while
washing to flush away dirt that might
scratch the finishes during the
washing operation.
4. Hose dirt and grime from the entire
chassis.
If an oil leak develops, you will be able to
detect it easier.
Corrosive materials used for ice and snow
removal and dust control can collect on the
underbody. If these materials are not
removed, accelerated corrosion (rust) can
occur on underbody parts such as fuel
lines, frames, floor pan, and exhaust
system, even though they have been
provided with corrosion protection.
At least every spring, flush these materials
from the under body with plain water. Be
sure to clean any area where mud and
other debris can collect. Sediment packed
in closed areas of the frame should be
loosened before being flushed. If desired,
your dealer can do this service for you.
5. Wipe everything dry with a chamois
to avoid water spots. To prevent
water spotting, dry off the cosmetic
surfaces with a clean cloth or
chamois.
6. Remove road tar with an automotive
type tar remover or mineral spirits.
7. After cleaning and drying, apply a
quality automotive wax.
Care of Display Screens on the
Dashboard
From time to time it may be necessary to
clean the display screen.
To clean the screen, dampen a clean, soft,
lint-free cloth with water only. A mild glass
cleaner that does not contain alcohol or
ammonia may also be used. Cleaners that
contain alcohol and/or ammonia will
eventually dry-out, crack and "yellow" the
screen. Wipe the screen gently back and
forth. You can also use a commercial
cleaner especially designed for LCD
screens.
Cooling System
Maintenance
Information about concentration and
condition of coolant, including filter.
Your engine’s cooling system is standard
with Nitrited forumulated Extended Life
Coolant (ELC) that meets or exceeds
ASTM D 6210 requirements. Nitrite-Free
Extended Life Antifreeze/Coolant can be
used if it meets ASTM D6210 and
Cummins CES 14439. ELC consists of a
mixture of ethylene glycol, water, and
nitrited organic acid technology (NOAT)
corrosion inhibitors. ELC prevents
corrosion and scale formation as well as
