AFTER STARTING

To optimize energy efficiency, the vehicle will automati-
cally control engine operation.
TO TURN OFF THE VEHICLE USING
ENGINE START/STOP BUTTON
1. Place the gear selector in PARK, then push and
release the ENGINE START/STOP button.
2. The ignition button indicator will return to the OFF
position.
3. If the gear selector is not in PARK, with vehicle
speed less than 5 mph (8 km/h), when the ENGINE
START/STOP button is pushed, the instrument clus-
ter display will display a "Vehicle Not In Park" mes-
sage, and the vehicle will remain running.
4. If the gear selector is not in PARK, with vehicle
speed greater than 5 mph (8 km/h), when the
ENGINE START/STOP button is pushed continuously
for at least two seconds (or three short pushes in a
row), the vehicle ignition will exit the Ready mode
and enter Accessory mode. Never leave a vehicle
out of the PARK position, or it could roll.
NOTE:
This vehicle is equipped with an automatic shut-
down feature. If the vehicle is left in a READY state
(vehicle running) with the gear selector in PARK for
30 minutes, the vehicle will automatically turn itself
off.
The vehicle provides automatic notification using a
three horn chirp alert, cluster chiming, and a cluster
message ("Key Fob Has Left The Vehicle") if the
vehicle was not turned off (still "Ready to Drive")
and a valid key fob for the vehicle is not detected
within the passenger cabin, following the opening
and closing of any passenger compartment door
(requires all doors to be closed before the key fob
check will occur). These automatic alerts are to
remind the driver to turn off the vehicle before leav-
ing it, as well as, to let the driver know that the vehi-
cle's key fob may have been unintentionally
removed from the vehicle by an exiting passenger.
After providing the horn chirp alert, additional auto
chirps will be inhibited until the gear selector has
been moved out of PARK or ignition cycled.

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 recommended viscosity and quality grades
page 346.
STARTING AND OPERATING
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.
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.
ENGINE BREAK-IN RECOMMENDATIONS —

6.4L ENGINE (IF EQUIPPED)

This breaking in occurs mainly during the first
500 miles (805 km) and continues through the first oil
change interval.
It is recommended for the operator to observe the fol-
lowing driving behaviors during the new vehicle break-in
period:
0 to 100 miles (0 to 161 km):
Do not allow the engine to operate at idle for an
extended period of time.
Press the accelerator pedal slowly and not more
than halfway to avoid rapid acceleration.
Avoid aggressive braking.
Drive with the engine speed below 3,500 RPM.
Maintain vehicle speed below 55 mph (88 km/h)
and observe local speed limits.
