ENGINE BREAK-IN RECOMMENDATIONS —

DIESEL ENGINE

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.
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 the
recommended viscosity and quality grades
Ú page 475.
NOTE:
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.

PARKING BRAKE

E P B (EPB)
LECTRIC ARK RAKE
Your vehicle is equipped with an EPB that offers
simple operation, and some additional features
that make the parking brake more convenient
and useful.
The parking brake is primarily intended to
prevent the vehicle from rolling while parked.
Before leaving the vehicle, make sure that the
parking brake is applied. Also, be certain to
leave the transmission in PARK.
You can engage the parking brake in two ways:
Manually, by applying the parking brake

switch.
Automatically, by enabling the Auto Park

Brake feature in the customer programmable
features section of the Uconnect settings.
STARTING AND OPERATING
The parking brake switch is located on the
instrument panel to the left of the steering
wheel (below the headlamp switch).
Electric Park Brake Switch
To apply the parking brake manually, pull up on
the switch momentarily. You may hear a slight
sound from the back of the vehicle while the
parking brake engages. Once the park brake is
fully engaged, the BRAKE telltale light in the
instrument cluster and an indicator on the
switch will illuminate. If your foot is on the brake
pedal while you apply the parking brake, you
may notice a small amount of brake pedal
movement. The parking brake can be applied
even when the ignition switch is OFF but the
BRAKE telltale light will not illuminate, however,
it can only be released when the ignition is in
the ON/RUN mode.
