Oil Level
The 3.0L engine does not have a
traditional “dipstick” and there is no
need to manually check the oil level
Úpage 316.
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message will
display in the instrument cluster display for five seconds
after a single chime has sounded, to indicate the next
scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate, dependent upon
your personal driving style and environmental conditions.
Unless reset, this message will continue to display each
time the ignition is placed in the ON/RUN position. To turn
off the message temporarily, push and release the OK or
arrow buttons. To reset the oil change indicator system
(after performing the scheduled maintenance), refer to
the following procedure.3

122STARTING AND OPERATING
COLD WEATHER OPERATION
(B
ELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater
(available from an authorized dealer) is recommended.
AFTER STARTING
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
TURBOCHARGER “COOL DOWN” —
3.0L E
NGINE 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.
ENGINE BREAK-IN RECOMMENDATIONS
An initial break-in period is recommended for the
powertrain (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
considered 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
Úpage 376.
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 feature
in the customer programmable features section of the
Uconnect settings.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result. ONLY USE OILS THAT
ARE API APPROVED
Úpage 376.

194STARTING AND OPERATING
When To Use 4WD LOW — If Equipped
When off-road driving, shift to 4WD LOW for additional
traction. This range should be limited to extreme
situations such as deep snow, mud, or sand where
additional low speed pulling power is needed. Vehicle
speeds in excess of 25 mph (40 km/h) should be avoided
when in 4WD LOW.
Driving Through Water
Although your vehicle is capable of driving through water,
there are a number of precautions that must be
considered before entering the water.
NOTE:Your vehicle is capable of water fording in up to 20 inches
(51 cm) of water, while crossing small rivers or streams. To
maintain optimal performance of your vehicle's heating
and ventilation system it is recommended to switch the
system into recirculation mode during water fording. Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle. If you must
drive through water, try to determine the depth and the
bottom condition (and location of any obstacles) prior to
entering. Proceed with caution and maintain a steady
controlled speed less than 5 mph (8 km/h) in deep water
to minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm run-off),
avoid crossing until the water level recedes and/or the
flow rate is reduced. If you must cross flowing water avoid
depths in excess of 9 inches (23 cm). The flowing water
can erode the streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are
downstream of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than 24 inches
(60 cm), and reduce speed appropriately to minimize
wave effects. Maximum speed is 5 mph (8 km/h).Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to ensure the fluids have not been
contaminated. Contaminated fluid (milky, foamy in
appearance) should be flushed/changed as soon as
possible to prevent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4WD LOW if necessary
Úpage 129. Only shift into a lower gear to maintain
forward motion. Over-revving the engine can spin the
wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads, because
engine braking may cause skidding and loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the conditions
at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to 4WD LOW. Use
FIRST gear and 4WD LOW for very steep hills.
WARNING!
Do not drive in 4WD LOW on dry pavement; driveline
damage may result. 4WD LOW locks front and rear
drivelines together and does not allow for differential
action between the front to rear driveshafts. Driving in
4WD LOW on pavement will cause driveline binding;
use only on wet or slippery surfaces.
CAUTION!
When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering as
a precaution, and check all fluids afterward. Driving
through water may cause damage that may not be
covered by the New Vehicle Limited Warranty.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the lug nut/bolt torque for tightness. Check the
tires (including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel or brake fluid leaks are
suspected, the cause should be located and corrected
immediately.
EXHAUST GAS
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system. Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have an authorized dealer inspect the complete
exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO), follow
these safety tips:

Do not run the engine in a closed garage or in
confined areas any longer than needed to move your
vehicle in or out of the area.
 If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation mode.
 If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
 Guard against carbon monoxide with proper mainte -
nance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi -
tions repaired promptly. Until repaired, drive with all
side windows fully open.
