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 temperature
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 loa
d 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

NOTE:
NON-DETERGENT OR STRAIGHT MINERAL OILS

NEVER BE USED.
PARKING BRAKE
ELECTRIC PARK BRAKE (EPB)
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.
The parking brake switch is located on the
inst
rument 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
swit
ch 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.
NOTE:
The EPB fault light will illuminate if the EPB switch
is h
eld for longer than 20 seconds in either the
released or applied position. The light will extin
-
guish upon releasing the switch.
