Regional Haul Model Operator's Manual - Peterbilt Motors Company

CAB MAINTENANCE
Your Peterbilt Dealer has a number of vehicle-care products
and can advise you on which ones to use for cleaning
the exterior and interior of your vehicle.
CAUTION: Do not aim the water jet directly at
door locks or latch. Tape the key holes to prevent
water from seeping into the lock cylinders.
Water in lock cylinders should be
removed with compressed air. To prevent
locks from freezing in the winter, squirt glycerin
or lock deicer into the lock cylinders.
Washing the Exterior
1. Begin by spraying water over the dry surface to
remove all loose dirt before applying the car wash and
wax solution.
• Do not wash the vehicle in direct sunshine.
• Do not spray water directly into any 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.
PREVENTIVE MAINTENANCE
• 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. 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.
5. Remove road tar with an automotive type tar remover
or mineral spirits.
6. After cleaning and drying, apply a quality automotive
wax.
NOTE: To allow enough time for your truck's finish to
cure, wait at least thirty days after the date of manufacture
before waxing.
• Do not apply wax in the hot sun
• Never dust off dry surfaces with a cloth because it will
scratch the finishes.
