TURBOCHARGER "COOL DOWN" —
3.0L ENGINE ONLY
The 3.0L engine is equipped with an after-run pump to
cool the turbocharger after the engine is shut off.
Depending on the type of driving and the amount of
cargo, the pump will run for up to 20 minutes after the
engine has been shut off to circulate coolant through
the turbocharger. Although the pump is rubber-mounted
for quiet operation, it is normal to hear it running during
this time.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater must be plugged in at least
one hour to have an adequate warming effect on the
engine.
The engine block heater cord is coiled and strapped
right behind the engine air cleaner filter assembly from
the manufacturer.
WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt elec-
trical cord could cause electrocution.

ENGINE BREAK-IN RECOMMENDATIONS

An initial break-in period is recommended for the pow-
ertrain (engine, transmission, axle, etc.) in your vehicle.
Adhering to the following guidelines will contribute to
improved longevity, fuel economy, and performance.
Drive moderately during the first 100 miles (160 km).
After that, for the first 500 miles (800 km), avoid long
periods at constant speed. Varying speed, engine RPM,
and throttle position is desirable.
Avoid high performance, severe off-road, and towing for
the first 500 miles (800 km).
NOTE:
A new engine may consume some oil during its first few
thousand miles (km) of operation. This should be con-
sidered a normal part of the break-in and not inter-
preted as a problem. For engines not equipped with an
oil level sensor, please check your oil level frequently
during the break-in period. Add manufacturer-approved
oil as required page 316.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result. ONLY USE OILS
THAT ARE API APPROVED page 316.
STARTING AND OPERATING

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 EPB switch.
•
Automatically, by enabling the Auto Park Brake fea-
ture in the customer programmable features section
of the Uconnect settings.
The EPB switch is located on the instrument panel to
the left of the steering wheel (below the headlamp
switch).
