during the pre-heat process, When the
engine “Wait To Start” telltale goes off the
engine will automatically crank.
3. The system will automatically engage thestarter to crank the engine. If the vehicle
fails to start, the starter will disengage
automatically after 30 seconds.
4. If you wish to stop the cranking of the engine prior to the engine starting, push
the ENGINE START/STOP button again.
5. Check that the oil pressure warning light has turned off.
6. Release the parking brake.Engine Warm Up
Avoid full throttle operation when the engine
is cold. When starting a cold engine, bring
the engine up to operating speed slowly to
allow the oil pressure to stabilize as the
engine warms up.
NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,200 RPM during the
warm-up period, especially in cold ambient
temperature conditions.
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 accelera
-
tion 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 consis -
tent with anticipated climate conditions
under which vehicle operations will occur.
For the recommended 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 inter -
preted as a problem.
CAUTION!
To prevent damage to the starter, do not
crank continuously for more than 10
seconds at a time. Wait 10 to 15 seconds
before trying again.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.

Auto Park Brake
The electric park brake can be programmed
to be applied automatically whenever the
vehicle is at a standstill and the automatic
transmission is placed in PARK, or with a
manual transmission, whenever the ignition
is turned “OFF”. Auto Park Brake is enabled
and disabled by customer selection through
the Customer Programmable Features
section of the Uconnect Settings.
Any single auto park brake application can
be bypassed by pushing the EPB switch to
the release position while the transmission is
placed in PARK.
WARNING!
Never use the PARK position as a substi-
tute for the parking brake. Always apply
the parking brake fully when exiting the
vehicle to guard against vehicle move-
ment and possible injury or damage.
When exiting the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, 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 unat -
tended is dangerous for a number of
reasons. A child or others could be seri -
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
Do not leave the key fob in or near the
vehicle, (or in a location accessible to
children), and do not leave the ignition
in the ACC or ON/RUN mode. A child
could operate power windows, other
controls, or move the vehicle.
Be sure the parking brake is fully disen -
gaged before driving; failure to do so can
lead to brake failure and a collision.
Always fully apply the parking brake
when leaving your vehicle, or it may roll
and cause damage or injury. Also be
certain to leave the transmission in
PARK. Failure to do so may allow the
vehicle to roll and cause damage or
injury.

Driving the vehicle with the parking brake
engaged, or repeated use of the parking
brake to slow the vehicle may cause
serious damage to the brake system.

WARNING! (Continued) CAUTION!
If the Brake System Warning Light remains
on with the parking brake released, a
brake system malfunction is indicated.
Have the brake system serviced by an
authorized dealer immediately.

SafeHold
SafeHold is a safety feature of the Electric
Park Brake System that will engage the park
brake automatically if the vehicle is left
unsecured while the ignition is in ON/RUN.
For automatic transmissions, the park brake
will automatically engage if all of the
following conditions are met:
The vehicle is at a standstill.
There is no attempt to depress the brake
pedal or accelerator pedal.
The seat belt is unbuckled.
The driver door is open.
For manual transmissions, the park brake
will automatically engage if all of the
following conditions are met:
The vehicle is at a standstill.
There is no attempt to depress the brake
pedal or accelerator pedal.
The clutch pedal is not pressed.
The seat belt is unbuckled.
The driver door is open.
MANUAL TRANSMISSION —
IF EQUIPPED NOTE:
During cold weather, you may experience
increased effort in shifting until the trans -
mission fluid warms up. This is normal.
Shifting
Fully press the clutch pedal before shifting
gears. As you release the clutch pedal, lightly
press the accelerator pedal.
You should always use FIRST gear when
starting from a standing position.
WARNING!
You or others could be injured if you leave
the vehicle unattended without having the
parking brake fully applied. The parking
brake should always be applied when the
driver is not in the vehicle, especially on
an incline.
CAUTION!
Never drive with your foot resting on the
clutch pedal, or attempt to hold the
vehicle on a hill with the clutch pedal
partially engaged, as this will cause
abnormal wear on the clutch.
Do not drive with your hand resting on
the gear selector as the force exerted,
even if slight, could lead over time to
premature wear of the gearbox internal
components.

When operating your vehicle in 4WD LOW,
the engine speed is approximately three
times that of the normal driving mode at a
given road speed. Take care not to overspeed
the engine and do not exceed 50 mph
(80 km/h).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference
will adversely affect shifting and cause
damage to the driveline components.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go
faster than road conditions permit.
Shift Positions
For additional information on the appropriate
use of each 4WD system mode position, see
the information below:
NEUTRAL (N)
This range disengages the driveline from the
powertrain.
4WD LOW
This range is for low speed four-wheel drive.
It provides an additional gear reduction
which allows for increased torque to be deliv-
ered to both the front and rear wheels while
providing maximum pulling power for loose,
slippery road surfaces only. Do not exceed
25 mph (40 km/h).
NOTE:
Refer to “Selec-Terrain — If Equipped” for
further information on the various positions
and their intended usages.
Shifting Procedures
Shifting Into 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0
to 5 km/h), the ignition in the ON mode and
the engine running, shift the transmission
into NEUTRAL, and push the “4WD LOW”
button once. The “4WD LOW” indicator light
in the instrument cluster will begin to flash
and remain on solid when the shift is
complete.
2-Speed 4x4 Switch (With Rear Lock)
NOTE:
If shift conditions/interlocks are not met, a
message will flash from the instrument
cluster display with instructions on how to
complete the requested shift.
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
power transfer unit in the NEUTRAL (N)
position without first fully engaging the
parking brake. The NEUTRAL (N) position
disengages both the front and rear
driveshafts from the powertrain and will
allow the vehicle to roll, even if the
automatic transmission is in PARK (P) (or
manual transmission is in gear). The
parking brake should always be applied
when the driver is not in the vehicle.
