ENGINE BREAK-IN RECOMMENDATIONS
— GASOLINE ENGINE (IF EQUIPPED)
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
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 the recommended viscosity and quality grades
page 361.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.
NOTE:
A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. 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 temperature
indicators.
•
Check the coolant and oil levels frequently.
•
Vary throttle position at highway speeds when carry-
ing 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
page 361. NON-DETERGENT OR STRAIGHT MIN-
ERAL OILS MUST NEVER BE USED.
STARTING AND OPERATING
PARKING BRAKE
Before exiting the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave an auto-
matic 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 transmis-
sion is placed in gear, the Brake Warning Light will
flash if vehicle speed is detected. A chime will sound
if the vehicle speed is over 5 mph (8 km/h) to alert
the driver. Fully release the parking brake before
attempting to move the vehicle.
