144 STARTING AND OPERATING
For the recommended viscosity and quality
grades see Ú page 438.
NOTE:
A new engine may consume some oil during its
first few thousand miles (kilometers) of opera-
tion. This should be considered a normal part of
the break-in and not interpreted as a problem.
ENGINE BREAK-IN RECOMMENDATIONS —
DIESEL ENGINE (IF EQUIPPED)
The diesel engine does not require a break-in
period due to its construction. Normal operation
is allowed, providing the following
recommendations are followed:
Warm up the engine before placing it under
load.
Do not operate the engine at idle for
prolonged periods.
Use the appropriate transmission gear to
prevent engine lugging.
Observe vehicle oil pressure and tempera-
ture indicators.
Check the coolant and oil levels frequently.
Vary throttle position at highway speeds
when carrying or towing significant weight.
NOTE:
Light duty operation such as light trailer towing
or no load operation will extend the time before
the engine is at full efficiency. Reduced fuel
economy and power may be seen at this time.
The engine oil installed in the engine at the
factory is a high-quality energy conserving type
lubricant. Oil changes should be consistent with
anticipated climate conditions under which
vehicle operations will occur. For recommended
viscosity and quality grades see Ú page 438.
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.
PARKING BRAKE
Before exiting the vehicle, make sure that the
parking brake is fully applied. Also, be certain to
leave an automatic transmission in PARK, or
manual transmission in REVERSE or FIRST
gear.
The parking brake lever is located in the center
console. To apply the parking brake, pull the
lever up as firmly as possible. To release the
parking brake, pull the lever up slightly, push
the center button, then lower the lever
completely.
Parking Brake Lever
When the parking brake is applied with the
ignition switch ON, the “Brake Warning Light” in
the instrument cluster will illuminate.
NOTE:
When the parking brake is applied and the
automatic transmission is placed in gear, the
“Brake Warning Light” will flash. If vehicle
speed is detected, a chime will sound to alert
the driver. Fully release the parking brake
before attempting to move the vehicle.
This light only shows that the parking brake is
applied. It does not show the degree of brake
application.
CAUTION!
Never use Non-Detergent Oil or Straight Min-
eral Oil in the engine or damage may result.
