PART 7: STARTING & OPERATING THE VEHICLE
PB1319 (CAT. NO. 5296 ) —66— 22-01691 (R02/02)
Transmission Warmup
In cold weather you may find shifting sluggish when you first start the
engine. Transmission warmup is especially important at this time, but
it is always a good idea to warm up your transmission before starting
out on the road.
To warm up the transmission lubricating oil during engine warmup,
with a single transmission:
NOTE: Keep the engine exhaust system and the vehicle’s ventila-
tion system properly maintained. It is recommended that the vehi-
cle’s exhaust system and cab be inspected
•
By a competent technician every 15,000 miles
•
When a change is noticed in the sound of the exhaust system
•
If the exhaust system, underbody, or cab is damaged
NOTE: To allow for proper operation of the vehicle ventilation
system, keep the inlet grille at the base of the windshield clear
of snow, ice, leaves and other obstructions at all times.
NOTE: Do not stay in the vehicle with the engine running or
idling for more than 10 minutes with the vehicle’s Heater / AC
ventilation system in RECIRC or at LOW FAN SPEED. Even
with the ventilation system On, running the engine while parked
or stopped for prolonged periods of time is not recommended.
NOTE: If other vehicles are parked next to you idling, move
your vehicle or do not stay in your vehicle for prolonged periods
of time.
WARNING! Do not operate this vehicle if you notice a
gradual or sudden increase in cable shift effort or a
decrease in the usable travel. Take the vehicle to the
nearest authorized Peterbilt dealer for repair. Failure to
correct either of these conditions could result in serious
injury or death.
CAUTION: Cables are designed to be contaminant resis-
tant, not contaminant proof. Protect cable from contami-
nants, chemicals, and physical damage which may damage
the control cable.
NOTE: Shift control cables are lubricated for life and are non-
repairable. The cables cannot be lubricated and/or repaired. If
you detect a broken seal, moisture, or if the cable has frozen,
the shift cable must be replaced. Do not apply heat to thaw or
improve performance of the cables.
