114GETTING TO KNOW YOUR INSTRUMENT PANEL
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is
displayed to indicate that the tire pressure is
lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel consumption may not
be guaranteed.
Should one or more tires be in the condition mentioned
previously, the display will show the indications
corresponding to each tire.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires. As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire pressure
telltale when one or more of your tires is significantly
underinflated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check your tires
as soon as possible, and inflate them to the proper
pressure. Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underinflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or
wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to
function properly
Úpage 252.
Towing Hook Breakdown Warning Light —
If Equipped
This light illuminates when there is a failure
with the tow hook. Contact an authorized
dealer for service.
YELLOW INDICATOR LIGHTS
4WD Low Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the 4WD Low mode. The front and rear
driveshafts are mechanically locked together
forcing the front and rear wheels to rotate at
the same speed. Low range provides a greater gear
reduction ratio to provide increased torque at the wheels
Úpage 129.
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended that you
take your vehicle to an authorized dealer to have your
sensor function checked.

23_WS_OM_EN_USC_t.book Page 114

STARTING AND OPERATING121
4WD LOW — If Equipped
AutoPark will be disabled when operating the vehicle in
4WD LOW.
The message “AutoPark Disabled ” will be displayed in the
instrument cluster.
Additional customer warnings will be given when both of
these conditions are met:
 Vehicle is not in PARK
 Driver’s door is ajar
The message “ AutoPark Not Engaged ” will be displayed in
the instrument cluster. A warning chime will continue until
you shift the vehicle into PARK or the driver’s door is
closed.
ALWAYS DO A VISUAL CHECK
that your vehicle is in PARK
by looking for the "P" in the instrument cluster display and
on the gear selector. As an added precaution, always apply
the parking brake when exiting the vehicle.
EXTENDED PARK STARTING
NOTE:Extended Park condition occurs when the vehicle has not
been started or driven for at least 30 days.

1. Install a battery charger or jumper cables to the battery to ensure a full battery charge during the
crank cycle.

2. Press and hold the brake pedal while pushing the ENGINE START/STOP button once.
3. If the engine fails to start within 10 seconds, wait 10 to 15 seconds to allow the starter to cool, then
repeat the Extended Park Starting procedure.
4. If the engine fails to start after eight attempts, allow the starter to cool for at least 10 minutes, then repeat
the Extended Park Starting procedure.
IF ENGINE FAILS TO START
If the engine fails to start after you have followed the
“Normal Starting” procedure and has not experienced an
extended park condition as defined previously, it may be
flooded. Push the accelerator pedal all the way to the floor
and hold it there while the engine is cranking. This should
clear any excess fuel in case the engine is flooded.
The starter motor will engage automatically, run for
10 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!
If vehicle speed is above 1.2 mph (1.9 km/h), the
transmission will default to NEUTRAL until the vehicle
speed drops below 1.2 mph (1.9 km/h). A vehicle left in
the NEUTRAL position can roll. As an added precaution,
always apply the parking brake when exiting the vehicle.
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.
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 trans -
mission 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.
 If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type of
start can be dangerous if done improperly
Úpage 301.
CAUTION!
To prevent damage to the starter, do not continuously
crank the engine for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.

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.

23_WS_OM_EN_USC_t.book Page 122

178STARTING AND OPERATING
VEHICLE LOADING
GROSS VEHICLE WEIGHT RATING
(GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR.
PAYLOAD
The payload of a vehicle is defined as the allowable weight
a vehicle can carry, including the weight of the driver, all
passengers, options and cargo.
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles, or suspension
components sometimes specified by purchasers for
increased durability, do not necessarily increase the
vehicle's GVWR or GAWR.
TIRE SIZE
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
RIM SIZE
This is the rim size that is appropriate for the tire size
listed.
INFLATION PRESSURE
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
CURB WEIGHT
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
LOADING
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to ensure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should then
be determined separately to be sure that the load is
properly distributed over the front and rear axles.
Weighing the vehicle may show that the GAWR of either
the front or rear axles has been exceeded but the total
load is within the specified GVWR. If so, weight must be shifted from front to rear or rear to
front as appropriate until the specified weight limitations
are met. Store the heavier items down low and be sure
that the weight is distributed equally. Stow all loose items
securely before driving.
NOTE:

Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles and
the way the brakes operate.
 Air suspension vehicle may limit off-road heights if
loaded beyond recommended values for vehicle GVWR
and GAWR.
TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with your
vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
WARNING!
Do not load your vehicle any heavier than the GVWR or
the maximum front and rear GAWR. If you do, parts on
your vehicle can break, or it can change the way your
vehicle handles. This could cause you to lose control.
Overloading can shorten the life of your vehicle.

23_WS_OM_EN_USC_t.book Page 178

SAFETY253
(Continued)
For information on how to properly inflate the vehicle’s
tires, see
Úpage 349.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low pressure warning
threshold for any reason, including low temperature
effects, or natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above recommended cold
tire pressure. Once the low tire pressure warning has been
illuminated, the tire pressure must be increased to the
recommended cold tire pressure in order for the TPMS
Warning Light to be turned off.
NOTE:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
The system will automatically update and the TPMS
Warning Light will extinguish once the updated tire
pressures have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h) to
receive this information. For example, your vehicle has a recommended cold
(parked for more than three hours) tire pressure of 33 psi
(227 kPa). If the ambient temperature is 68°F (20°C) and
the measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 24 psi (165 kPa). This tire
pressure is sufficiently low enough to turn on the TPMS
Warning Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa), but the
TPMS Warning Light will still be on. In this situation, the
TPMS Warning Light will turn off only after the tires have
been inflated to the vehicle’s recommended cold tire
pressure value.NOTE:

The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire failure
or condition.
 The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
 Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla -
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
 The TPMS is not a substitute for proper tire mainte -
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if underinflation has not reached the level to trigger illu -
mination of the TPMS Warning Light.
 Seasonal temperature changes will affect tire pres -
sure, and the TPMS will monitor the actual tire pres -
sure in the tire.
CAUTION!
 The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warn -
ings have been established for the tire size equipped
on your vehicle. Undesirable system operation or
sensor damage may result when using replacement
equipment that is not of the same size, type, and/or
style. The TPMS sensor is not designed for use on
aftermarket wheels and may contribute to a poor
overall system performance or sensor damage.
Customers are encouraged to use Original Equip -
ment Manufacturer (OEM) wheels to ensure proper
TPMS feature operation.
 Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealership to have your sensor func -
tion checked.
 After inspecting or adjusting the tire pressure, always
reinstall the valve stem cap. This will prevent mois -
ture and dirt from entering the valve stem, which
could damage the Tire Pressure Monitoring System
sensor.
CAUTION!

23_WS_OM_EN_USC_t.book Page 253

SERVICING AND MAINTENANCE317
NOTE:
After adding oil to the engine, always reinstall the oil
cap securely by rotating clockwise until it stops. Never
run the engine without the oil fill cap as this could
cause an oil leak.
 Because the oil level is automatically detected only
when the engine has been off and restarted (after four
minutes), the system cannot immediately detect a
sudden drop in oil level while driving (for example, if the
oil pan starts to leak due to damage during an off-road
event).
CHECKING OIL LEVEL — 5.7L & 6.4L
E
NGINES
To ensure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a fully
warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings.
There are four possible dipstick types:
 Crosshatched zone.
 Crosshatched zone marked SAFE.
 Crosshatched zone marked with MIN at the low end of
the range and MAX at the high end of the range.
 Crosshatched zone marked with dimples at the MIN
and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 qt (1 L) of oil when the reading is at the low end
of the dipstick range will raise the oil level to the high end
of the range marking.
ADDING WASHER FLUID
The instrument cluster display will indicate when the
washer fluid level is low. When the sensor detects a low
fluid level, the Low Washer Fluid Warning Light will turn on
and the "Washer Fluid Low" message will be displayed.
The fluid reservoir for the windshield washers and the rear
window washer is shared. The fluid reservoir is located in
the engine compartment, be sure to check the fluid level
at regular intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze). When
refilling the washer fluid reservoir, take some washer fluid
and apply it to a cloth or towel and wipe clean the wiper
blades, this will help blade performance. To prevent
freeze-up of your windshield washer system in cold
weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
NOTE:Use care when filling under hood fluids such as engine oil,
washer fluid, antifreeze, etc. to minimize spillage onto top
of engine. Any excess fluid that is spilled onto the top of
the engine should be removed using compressed air or an
absorbent cloth.
CAUTION!
If the “Critically Low or Critically High” Oil Level Warning
Light is illuminated, the following steps should be
taken:
Critically Low: add two quarts of manufacturer speci -
fied oil as soon as possible
Úpage 376. Continuing
to operate the vehicle with “Critically Low” oil level
may damage the engine.
 Critically High: contact an authorized dealer for
service. Continuing to operate the vehicle with “Criti -
cally High” oil level may damage the engine.
Do not use any oils that are not manufacturer specified
and API approved.
Used engine oil and oil filters contain substances which
are harmful to the environment. When oil and filters are
changed contact an authorized dealer and dispose of in
a safe and responsible manner.
WARNING!
Commercially available windshield washer solvents are
flammable. They could ignite and burn you. Care must
be exercised when filling or working around the washer
solution.

TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary areas
are affected by improper tire pressure:
Safety
 Fuel Economy
 Tread Wear
 Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation affect the stability of
the vehicle and can produce a feeling of sluggish response
or over responsiveness in the steering.
NOTE:

Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
 Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnormal
wear patterns and reduced tread life, resulting in the need
for earlier tire replacement. Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver's side B-pillar or rear edge of the driver's side door.
At least once a month:

Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual judg -
ment when determining proper inflation. Tires may look
properly inflated even when they are under-inflated.
 Inspect tires for signs of tire wear or visible damage.
Inflation pressures specified on the placard are always
“cold tire inflation pressure”. Cold tire inflation pressure is
defined as the tire pressure after the vehicle has not been
driven for at least three hours, or driven less than 1 mile
(1.6 km) after sitting for a minimum of three hours. The
cold tire inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
WARNING!
Overloading of your tires is dangerous. Overloading can
cause tire failure, affect vehicle handling, and increase
your stopping distance. Use tires of the recommended
load capacity for your vehicle. Never overload them.
WARNING!
 Improperly inflated tires are dangerous and can
cause collisions.
 Underinflation increases tire flexing and can result in
overheating and tire failure.
 Overinflation reduces a tire's ability to cushion shock.
Objects on the road and chuckholes can cause
damage that result in tire failure.
Overinflated or underinflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
 Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
 Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the right
or left.
 Always drive with each tire inflated to the
recommended cold tire inflation pressure.
WARNING!
CAUTION!
After inspecting or adjusting the tire pressure, always
reinstall the valve stem cap. This will prevent moisture
and dirt from entering the valve stem, which could
damage the valve stem.
