diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light
s t

arts to flash as soon as the tires lose traction and
the ESC system becomes active. The ESC
Activation/Malfunction Indicator Light also flashes
when TCS is active. If the ESC Activation/
Malfunction Indicator Light begins to flash during
acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road conditions.
The ESC OFF Indicator Light indicates the
customer has elected to have the
El

ectronic Stability Control (ESC) in a
reduced mode.
NOTE:
The ESC Activation/Malfunction Indicator Light
and the ESC OFF Indicator Light come on
momentarily each time the ignition is placed in
the ON position.
Each time the ignition is placed in the ON posi -
tion, the ESC system will be on even if it was
t u
rned off previously.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive
following the maneuver that caused the ESC
activation.
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a
complete stop while on an incline. If the driver
releases the brake while stopped on an incline,
HSA will continue to hold the brake pressure for a
short period. If the driver does not apply the
throttle before this time expires, the system will
release brake pressure and the vehicle will roll
down the hill as normal.
The following conditions must be met in order for
HS A

to activate:
The feature must be enabled.
The vehicle must be stopped.
The parking brake must be off.
The driver door must be closed.
The vehicle must be on a sufficient grade.
The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in forward
gear; vehicle backing uphill is in REVERSE gear).
HSA will work in REVERSE gear and all forward
gears. The system will not activate if the trans -
mission is in PARK or NEUTRAL. For vehicles
e q

uipped with a manual transmission, if the
clutch is pressed, HSA will remain active.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting using Uconnect
Settings, see
Ú page 122 for further information.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA is
not a substitute for active driving involvement. It
is always the driver’s responsibility to be
attentive to distance to other vehicles, people,
and objects, and most importantly brake
operation to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle. Failure to
follow these warnings can result in a collision or
serious personal injury.

not in the path of the vehicle, stationary objects
that are far away, oncoming traffic, or leading
vehicles with the same or higher rate of speed.
FCW disables in the same manner as ACC, and
will display a screen indicating that the feature
is unavailable when it has been disabled.
FCW Limited Warning
If the instrument cluster display reads “ACC/FCW
Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield”
momentarily, there may be a condition that limits
FCW functionality. Although the vehicle is still
drivable under normal conditions, the active
braking may not be fully available. Once the
condition that limited the system performance is
no longer present, the system will return to its full
performance state. If the problem persists, see an
authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster
display reads:
ACC/FCW Unavailable Service Required
Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault.
A l

though the vehicle is still drivable under normal
conditions, have the system checked by an
authorized dealer.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard pressure.
The tire pressure will vary with temperature by
a b

out 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature
decreases, the tire pressure will decrease. Tire
pressure should always be set based on cold
inflation tire pressure. This 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 a three hour period. The cold tire
i n
flation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
The tire pressure will also increase as the vehicle
is driven — this is normal and there should be no
adjustment for this increased pressure.
See
Ú page 225 on how to properly inflate the
vehicle’s tires.
The TPMS will warn the driver of a low tire pressure
i f

the tire pressure falls below the low-pressure
warning limit for any reason, including low
temperature effects and natural pressure loss
through the tire.
The TPMS will continue to warn the driver of low
t i

re pressure as long as the condition exists, and
will not turn off until the tire pressure is at or above the recommended cold placard pressure. Once the
low tire pressure warning (TPMS Warning Light)
illuminates, you must increase the tire pressure to
the recommended cold placard pressure in order
for the TPMS Warning Light to turn off. The system
will automatically update and the TPMS Warning
Light will turn off once the system receives the
updated tire pressures. The vehicle may need to be
driven for up to 20
minutes above 15 mph
( 2

4 km/h) in order for the TPMS to receive this
i n
formation.
NOTE:
When filling warm tires, the tire pressure may need
t o
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.
For example, your vehicle may have a
re
commended cold (parked for more than three
hours) placard pressure of 30 psi (207 kPa). If the
ambient temperature is 68°F (20°C) and the
measured tire pressure is 27 psi (186 kPa), a
temperature drop to 20°F (-7°C) will decrease the
tire pressure to approximately 23 psi (158 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 27 psi (186 kPa), but the TPMS
Warning Light will still be on. In this situation, the
TPMS Warning Light will turn off only after the tires
are inflated to the vehicle’s recommended cold
placard pressure value.

SAFETY 149
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. Underinflation also reduces fuel effi
-
ciency and tire tread life, and may affect the
v e

hicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate tire pressure gauge, even if underinflation
h a

s not reached the level to trigger illumination
of the TPMS Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
The Tire Pressure Monitoring System (TPMS) uses
w i

reless technology with wheel rim mounted
electronic sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the
receiver module
Ú page 254.
NOTE:
It is particularly important for you to check the tire
p r
essure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module.
Four Tire Pressure Monitoring System sensors.
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster.
Tire Pressure Monitoring System Warning Light.
Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System
(TPMS) Warning Light will illuminate in
t h
e instrument cluster and a chime will
sound when tire pressure is low in one or
more of the four active road tires. In addition, the
instrument cluster will display an “Inflate to XX”
message and a graphic showing the pressure
values of each tire with the low tire pressure values
shown in a different color.
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.
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 Equipment Manufacturer (OEM)
wheels to ensure proper TPMS feature opera -
tion.
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.
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 TPMS
sensor.

Tire Pressure Monitoring System Display
Low Tire Pressure Monitoring System Display

Should this occur, you should stop as soon as
p os

sible and inflate the tires with a low pressure
condition (those shown in a different color in the
instrument cluster graphic) to the vehicle’s
recommended cold placard pressure inflation
value as shown in the “Inflate to XX” message.
Once the system receives the updated tire pressures, the system will automatically update,
the graphic display in the instrument cluster will
change color back to the original color, and the
TPMS Warning Light will turn off. The vehicle may
need to be driven for up to 20
minutes above
1 5


mph (24 km/h) in order for the TPMS to receive
t h
is information.
NOTE:
When filling warm tires, the tire pressure may need
t o
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.
Service Tire Pressure System Warning
If a system fault is detected, the Tire Pressure
Monitoring System (TPMS) Warning Light will flash
on and off for 75 seconds and then remain on
solid. The system fault will also sound a chime. In
addition, the instrument cluster will display a
"Service Tire Pressure System" message for a
minimum of five seconds and then display dashes
(- -) in place of the pressure value to indicate which
sensor is not being received.
If the ignition switch is cycled, this sequence will
r e

peat, providing the system fault still exists. If the
system fault no longer exists, the TPMS Warning
Light will no longer flash, and the "Service Tire
Pressure System" message will no longer display,
and a pressure value will display in place of the
dashes. A system fault can occur due to any of the
following:
Signal interference due to electronic devices or
driving next to facilities emitting the same radio
frequencies as the TPMS sensors.
Accumulation of snow or ice around the wheels
or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors.
Vehicles With Compact Spare

1. T he compact spare tire or non-matching full
s
ize does not have a Tire Pressure Monitoring
System sensor. Therefore, the TPMS will not
monitor the pressure in the compact spare
tire.

2. I f you install the compact or non-matching full
s
ize spare tire in place of a road tire that has a
pressure below the low-pressure warning limit,
upon the next ignition key cycle, the TPMS
Warning Light will remain on and a chime will
sound. In addition, the graphic in the
instrument cluster will still display a different
color pressure value and an "Inflate to XX"
message.

SAFETY 151
3. After driving the vehicle for up to 20 minutes
ab
ove 15 mph (24 km/h), the TPMS Warning
Li g
ht will flash on and off for 75 seconds and
then remain on solid. In addition, the
instrument cluster will display a “Service Tire
Pressure System” message for five seconds
and then display dashes (- -) in place of the
pressure value.
4. F or each subsequent ignition key cycle, a
c
hime will sound, the TPMS Warning Light will
flash on and off for 75 seconds and then
remain on solid, and the instrument cluster will
display a “Service Tire Pressure System”
message for five seconds and then display
dashes (- -) in place of the pressure value.

5. O nce you repair or replace the original road tire
a
nd reinstall it on the vehicle in place of the
compact spare or non-matching full size, the
TPMS will update automatically. In addition, the
TPMS Warning Light will turn off and the graphic
in the instrument cluster will display a new
pressure value instead of dashes (- -), as long as
no tire pressure is below the low-pressure
warning limit in any of the four active road tires.
The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order
f o

r the TPMS to receive this information.

TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (TPMS) can
be deactivated if replacing all four wheel and tire
assemblies (road tires) with wheel and tire
assemblies that do not have TPMS sensors, such
as when installing winter wheel and tire
assemblies on your vehicle.
To deactivate the TPMS, first replace all four wheel
a n

d tire assemblies (road tires) with tires not
equipped with Tire Pressure Monitoring System
(TPMS) sensors. Then, drive the vehicle for
20 minutes above 15 mph (24 km/h). The TPMS
wi

ll chime, the TPMS Warning Light will flash on
and off for 75 seconds and then remain on. The
instrument cluster will display the “Service Tire
Pressure System” message and then display
dashes (--) in place of the pressure values.
Beginning with the next ignition cycle, the TPMS
wi
ll no longer chime or display the “Service Tire
Pressure System” message in the instrument
cluster but dashes (--) will remain in place of the
pressure values. To reactivate the TPMS, replace all four wheel and
t
i

re assemblies (road tires) with tires equipped with
TPMS sensors. Then, drive the vehicle for up to
20 minutes above 15 mph (24 km/h). The TPMS
w i

ll chime, the TPMS Warning Light will flash on
and off for 75 seconds and then turn off. The
instrument cluster will display the “Service Tire
Pressure System” message and then display
pressure values in place of the dashes. On the next
ignition cycle the "Service Tire Pressure System"
message will no longer be displayed as long as no
system fault exists.

lug nuts/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
ex

haust 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/lift -
gate/rear doors open, make sure that all
w i
ndows 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!
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
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.

192 IN CASE OF EMERGENCY
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. Then, shift
back and forth between DRIVE and REVERSE while
gently pressing the accelerator. Use the least
amount of accelerator pedal pressure that will
maintain the rocking motion, without spinning the
wheels or racing the engine.
NOTE:
For vehicles with automatic transmission: Shifts
between DRIVE and REVERSE can only be
achieved at wheel speeds of 5
mph (8 km/h) or
le

ss. Whenever the transmission remains in
NEUTRAL for more than two seconds, you must
press the brake pedal to engage DRIVE or
REVERSE.
Push the ESC OFF switch to place the Electronic
Stability Control (ESC) system in “Partial OFF”
mode, before rocking the vehicle
Ú page 139.
Once the vehicle has been freed, push the ESC
O F
F switch again to restore “ESC On” mode.CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission in
NEUTRAL for at least one minute after every five
rocking-motion cycles. This will minimize
overheating and reduce the risk of clutch or
transmission failure during prolonged efforts to
free a stuck vehicle.
WARNING!

Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may cause
damage, or even failure, of the axle and tires. A
tire could explode and injure someone. Do not
spin your vehicle's wheels faster than 30 mph
(4

8 km/h) or for longer than 30 seconds
c o
ntinuously without stopping when you are
stuck and do not let anyone near a spinning
wheel, no matter what the speed.

CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmis -
sion failure during prolonged efforts to free a
s t

uck vehicle.
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or
dr

ivetrain damage may result.
Revving the engine or spinning the wheels too
fast may lead to transmission overheating and
failure. It can also damage the tires. Do not
spin the wheels above 30 mph (48 km/h)
w h

ile in gear (no transmission shifting occur -
ring).

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
This vehicle is equipped with an automatic oil
change indicator system. The oil change indicator
system will remind you that it is time to take your
vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
ch

ange indicator message will illuminate. This
means that service is required for the vehicle.
Operating conditions such as frequent short-trips,
trailer tow, and extremely hot or cold ambient
temperatures will influence when the “Change Oil”
or “Oil Change Required” message is displayed.
Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km). The “Oil Change Required” message will be
di

splayed in the instrument cluster and a single
chime will sound, indicating that an oil change is
necessary.
An authorized dealer will reset the oil change
in
dicator message after completing the scheduled
oil change.
NOTE:
Under no circumstances should oil change
i n
tervals exceed 10,000 miles (16,000 km),
1 2

months or 350 hours of engine run time,
w h
ichever comes first. The 350 hours of engine
run or idle time is generally only a concern for fleet
customers. Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check tire pressure and look for unusual wear
or damage. Rotate tires at the first sign of irreg
-
ular wear, even if it occurs before your next
s c

heduled service.
Check the fluid levels of the coolant reservoir,
brake master cylinder, and power steering (if
equipped) and fill as needed.
Check function of all interior and exterior lights.
