Engine Break-In Recommendations - Diesel Engine (If Equipped); Parking Brake - Jeep GLADIATOR 2022 Owner's Manual

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
page 361. NON-DETERGENT OR STRAIGHT MIN-
ERAL 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 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 auto-
matic 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.
STARTING AND OPERATING
•
This light only shows that the parking brake is
applied. It does not show the degree of brake
application.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. For vehicles equipped
with an automatic transmission, apply the parking
brake before placing the gear selector in PARK, other-
wise the load on the transmission locking mechanism
may make it difficult to move the gear selector out of
PARK.
WARNING!
•
Never use the PARK position on an automatic
transmission as a substitute for the parking brake.
Always apply the parking brake fully when parked
to guard against vehicle movement and possible
injury or damage.
•
When exiting the vehicle, always remove the key
fob from the vehicle and lock your vehicle.
•
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a num-
ber of reasons. A child or others could be seriously
or fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
•
Do not leave the key fob in or near the vehicle, or
in a location accessible to children. A child could
operate power windows, other controls, or move
the vehicle.
•
Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to brake
failure and a collision.
