AutoPark — Rotary Shifter and 8-Speed Transmission
Only
AutoPark is a supplemental feature to assist in placing the
vehicle in PARK should the situations on the following
pages occur. It is a back up system and should not be relied
upon as the primary method by which the driver shifts the
vehicle into PARK. The conditions under which AutoPark will engage are
outlined on the following pages.
WARNING!
• Driver inattention could lead to failure to place the vehicle in PARK. ALWAYS DO A VISUAL CHECK
that your vehicle is in PARK by verifying that a solid
(not blinking) “P” is indicated in the Instrument
Cluster Display and near the gear selector. If the "P"
indicator is blinking, your vehicle is not in PARK. As
an added precaution, always apply the parking brake
when exiting the vehicle.
• AutoPark is a supplemental feature. It is not designed to replace the need to shift your vehicle into PARK. It is
a back up system and should not be relied upon as the
primary method by which the driver shifts the vehicle
into PARK.

seconds, and then disengage. Once this occurs, release the
accelerator pedal and the brake pedal, wait 10 to 15 seconds,
then repeat the “Normal Starting” procedure.
WARNING!
• Never pour fuel or other flammable liquid into the throttle body air inlet opening in an attempt to start the
vehicle. This could result in flash fire causing serious
personal injury.
• Do not attempt to push or tow your vehicle to get it started. Vehicles equipped with an automatic transmis -
sion cannot be started this way. Unburned fuel could
enter the catalytic converter and once the engine has
started, ignite and damage the converter and vehicle.

STARTING AND OPERATING 297
ENGINE BREAK-IN RECOMMENDATIONS
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 recom -
mended viscosity and quality grades, refer to “Fluids And
Lubricants” in “Technical Specifications”. 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. Please check your oil level with the engine oil
indicator often during the break in period. Add oil as
required.
PARKING BRAKE
Electric Park Brake (EPB)
Your vehicle is equipped with an Electric Park Brake System
(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 park brake is applied. Also, be certain to
leave the transmission in PARK.
You can engage the park brake in two ways:
• Manually, by applying the park brake switch.
• Automatically, by enabling the Auto Park Brake feature in
the customer programmable features section of the Ucon -
nect settings.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.5

NOTE:
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. Apply the park brake before
placing the gear selector in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the gear selector out of PARK. The parking brake
should always be applied whenever the driver is not in the
vehicle.

• Never use the PARK position 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 ignition 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 number 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 alocation accessible to children, and do not leave a
vehicle equipped with Keyless Enter-N-Go in the ACC
or ON/RUN mode. A child could operate power
windows, other controls, or move the vehicle.
