•Unstored Messages Until RUN
These messages deal primarily with the Re-
mote Start feature. This message type is dis-
played until the ignition is in the RUN state.
Examples of this message type are "Remote
Start Aborted - Door Ajar" and"Press Brake
Pedal and Push Button to Start".
• Five Second Unstored Messages
When the appropriate conditions occur, this
type of message takes control of the main
display area for five seconds and then returns to
the previous screen. Examples of this message
type are "Memory System Unavailable - Not in
Park" and"Automatic High Beams On".
The Reconfigurable Telltales section is divided
into the white telltales area on the right, amber
telltales in the middle, and red telltales on the left.

Compass / Temperature DisplayThe compass readings indicate the direction the
vehicle is facing. The EVIC will display one of
eight compass readings and the outside tem-
perature.
NOTE:
The system will display the last known out-
side temperature when starting the vehicle
and may need to be driven several minutes
before the updated temperature is dis-
played. Engine temperature can also affect
the displayed temperature; therefore, tem-
perature readings are not updated when the
vehicle is not moving.Automatic Compass Calibration
This compass is self-calibrating, which elimi-
nates the need to manually reset the compass.
When the vehicle is new, the compass may
appear erratic and the EVIC will display CAL
until the compass is calibrated. You may also
calibrate the compass by completing one or
more 360–degree turns (in an area free from
large metal or metallic objects) until the CAL
indicator displayed in the EVIC turns off. The
compass will now function normally.
NOTE:
A good calibration requires a level surface
and an environment free from large metallic
objects such as buildings, bridges, under-
ground cables, railroad tracks, etc.Compass Variance
Compass Variance is the difference between
Magnetic North and Geographic North. To com-
pensate for the differences the variance should
be set for the zone where the vehicle is driven,
per the zone map. Once properly set, the com-
pass will automatically compensate for the dif-
ferences, and provide the most accurate com-
pass heading. For the most accurate compass
performance, the compass must be set using
the following steps.
NOTE:
Keep magnetic materials away from the top
of the instrument panel, such as iPod’s,
Mobile Phones, Laptops and Radar Detec-
tors. This is where the compass module is
located, and it can cause interference with
the compass sensor, and it may give false
readings.
182

Forward Collision Warning — If EquippedThe Forward Collision Warning (FCW) feature
can be can be set to Far, set to Near or turned Off.
The default status of FCW is the Far setting. This
means the system will warn you of a possible
collision with the vehicle in front of you when you
are farther away. This gives you the most reaction
time. To change the setting for more dynamic
driving select the Near setting. This warns you of
a possible collision with the vehicle in front of you
when you are much closer. This allows for a more
dynamic driving experience. To change FCW sta-
tus press and release the SELECT button until a
check-mark appears next to the feature showing
the system has been activated or the check-mark
is removed showing the system has been deacti-
vated.
For further information, refer to ”Adaptive
Cruise Control (ACC)” in “Understanding The
Features Of Your Vehicle.”Park Assist System — If Equipped
The Rear Park Assist system will scan for
objects behind the vehicle when the transmis-
sion is in the REVERSE position and the vehicle
speed is less than 11 mph (18 km/h). The
system can be enabled with Sound Only or
Sound and Display. To make your selection,
scroll up or down until the preferred setting is
highlighted, then press and release the SE-
LECT button until a check-mark appears next to
the setting, showing that the setting has been
selected. Refer to “Rear Park Assist System” in
“Understanding The Features Of Your Vehicle”
for system function and operating information.
Blind Spot Alert — If Equipped
There are three selections when operating Blind
Spot Alert. By pressing and releasing the SE-
LECT button once, the Blind Spot Alert feature
can be activated in “Blind Spot: Lights Only”
mode. When this mode is selected the Blind
Spot Monitor (BSM) system is activated and will
only show a visual alert in the outside mirrors.
By pressing and releasing the SELECT button a
second time “Blind Spot: Lights/CHM” mode is
activated. In this mode the Blind Spot Monitor(BSM) will show a visual alert in the outside
mirrors as well as an audible alert when the turn
signal is on. When “Blind Spot: Off” is selected
the Blind Spot Monitor (BSM) system is deacti-
vated.
NOTE:
If your vehicle has experienced any damage
in the area where the sensor is located, even
if the fascia is not damaged, the sensor may
have become misaligned. Take your vehicle
to an authorized dealer to verify sensor
alignment. Having a sensor that is mis-
aligned will result in the BSM not operating
to specification.
Auto Unlock Doors
When this feature is selected, all doors will
unlock when the vehicle is stopped and the
transmission is in the PARK or NEUTRAL posi-
tion and the driver’s door is opened. To make
your selection, press and release the SELECT
button until a check-mark appears next to the
feature showing the system has been activated,
or the check-mark is removed showing the
system has been deactivated.

WARNING!
•The BAS cannot prevent the natural laws
of physics from acting on the vehicle, nor
can it increase the traction afforded by
prevailing road conditions.
• The BAS cannot prevent collisions, includ-
ing those resulting from excessive speed
in turns, driving on very slippery surfaces,
or hydroplaning.
•
The capabilities of a BAS-equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopardize
the user’s safety or the safety of others.
Electronic Roll Mitigation (ERM)This system anticipates the potential for wheel
lift by monitoring the driver’s steering wheel
input and the speed of the vehicle. When ERM
determines that the rate of change of the steer-
ing wheel angle and vehicle’s speed are suffi-
cient to potentially cause wheel lift, it then
applies the appropriate brake and may also reduce engine power to lessen the chance that
wheel lift will occur. ERM will only intervene
during very severe or evasive driving maneu-
vers.
ERM can only reduce the chance of wheel lift
occurring during severe or evasive driving ma-
neuvers. It cannot prevent wheel lift due to other
factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
WARNING!
Many factors, such as vehicle loading, road
conditions, and driving conditions, influence
the chance that wheel lift or rollover may
occur. ERM cannot prevent all wheel lift or
rollovers, especially those that involve leav-
ing the roadway or striking objects or other
vehicles. The capabilities of an ERM-
equipped vehicle must never be exploited in
a reckless or dangerous manner, which
could jeopardize the user’s safety or the
safety of others.
Electronic Stability Control (ESC)This system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for oversteering or
understeering of the vehicle by applying the
brake of the appropriate wheel to assist in
counteracting the oversteer or understeer con-
dition. Engine power may also be reduced to
help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the
oversteer or understeer condition.
•
Oversteer - when the vehicle is turning more
than appropriate for the steering wheel posi-
tion.
• Understeer - when the vehicle is turning less
than appropriate for the steering wheel posi-
tion.
253

NOTE:
To improve the vehicle’s traction when driv-
ing with snow chains, or starting off in deep
snow, sand, or gravel, it may be desirable to
switch to the “Partial Off” mode by pressing
the “ESC OFF” switch. Once the situation
requiring ESC to be switched to the “Partial
Off” mode is overcome, turn ESC back on by
momentarily pressing the “ESC OFF”
switch. This may be done while the vehicle
is in motion.
WARNING!
•When in "Partial Off" mode, the TCS func-
tionality of ESC, (except for the limited slip
feature described in the TCS section), has
been disabled and the "ESC Off Indicator
Light" will be illuminated. When in "Partial
Off" mode, the engine power reduction
feature of TCS is disabled, and the en-
hanced vehicle stability offered by the ESC
system is reduced.
• Trailer Sway control (TSC) is disabled
when the ESC system is in the "Partial Off"
mode.
4WD Low Range
Partial Off
This is the normal operating mode for ESC in
4WD LOW range. Whenever the vehicle is
started in 4WD LOW range, or the transfer case
(if equipped) is shifted from 4WD HIGH range or
NEUTRAL to 4WD LOW range, the ESC sys-
tem will be in the “Partial Off” mode.Trailer Sway Control (TSC)TSC uses sensors in the vehicle to recognize
an excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
The system may reduce engine power and
apply the brake of the appropriate wheel(s) to
counteract the sway of the trailer. TSC will
become active automatically once an exces-
sively swaying trailer is recognized. No driver
action is required. Note that TSC cannot stop all
trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer Tow-
ing” in “Starting and Operating” for further infor-
mation. When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will flash,
the engine power may be reduced and you may
feel the brakes being applied to individual
wheels to attempt to stop the trailer from sway-
ing. TSC is disabled when the ESC system is in
the “Partial Off” mode.
ESC OFF Switch

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.
Refer to “Tires – General Information” in
“Starting and Operating” for information on
how to properly inflate the vehicle’s tires.
The tire pressure will also increase as the
vehicle is driven - this is normal and there
should be no adjustment for this increased
pressure.
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 placard pressure.
Once the low tire pressure warning has been
illuminated, the tire pressure must be increased
to the recommended cold tire pressure in orderfor the Tire Pressure Monitoring Telltale Light to
be turned off. The system will automatically
update and the Tire Pressure Monitoring Telltale
Light will extinguish once the updated tire pres-
sures 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
placard 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 Tire Pressure Monitoring
Telltale Light. Driving the vehicle may cause the
tire pressure to rise to approximately 28 psi
(193 kPa), but the Tire Pressure Monitoring
Telltale Light will still be ON. In this situation, the
Tire Pressure Monitoring Telltale Light will turn
OFF only after the tires have been inflated to the
vehicle’s recommended cold tire pressure
value.CAUTION!
•
The TPMS has been optimized for the
original equipment tires and wheels. TPMS
pressures have been established for the
tire size equipped on your vehicle. Unde-
sirable system operation or sensor dam-
age may result when using replacement
equipment that is not of the same size,
type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use after-
market tire sealants or balance beads if
your vehicle is equipped with a TPMS, as
damage to the sensors may result.
• After inspecting or adjusting the tire pres-
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the Tire Pressure Monitoring Sensor.
267

NOTE:
•The TPMS is not intended to replace nor-
mal tire care and maintenance, or to pro-
vide 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 under-inflated
tire causes the tire to overheat and can
lead to tire failure. Under-inflation 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 maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure using an accurate tire gauge,
even if under-inflation has not reached
the level to trigger illumination of the Tire
Pressure Monitoring Telltale Light.
• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.Base SystemThe Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire pres-
sure levels. Sensors, mounted to each wheel as
part of the valve stem, transmit tire pressure
readings to the Receiver Module.
NOTE:
It is particularly important, for you to regu-
larly check the tire pressure in all of your
tires, and to maintain the proper pressure.
The TPMS consists of the following compo-
nents:
•Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
A low spare tire will not cause the Tire Pressure
Monitoring Telltale Light to illuminate, a warning
message to appear, or the chime to sound. The Tire Pressure Monitoring Telltale
Light will illuminate in the instrument
cluster, a “LOW TIRE PRESSURE”
message will display in the instrument
cluster for 5 seconds, an "Inflate to XXX"mes-
sage will be displayed and an audible chime will
be activated, when one or more of the four
active road tire pressures are low. Should this
occur, you should stop as soon as possible,
check the inflation pressure of each tire on your
vehicle, and inflate each tire to the vehicle’s
recommended cold placard pressure value dis-
played in the "Inflate to XXX" message. The
system will automatically update and the Tire
Pressure Monitoring Telltale Light will extin-
guish, 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.
268

The Tire Pressure Monitoring Telltale Light will
flash on and off for 75 seconds, and remain on
solid when a system fault is detected. In addi-
tion, a “SERVICE TPM SYSTEM” message
may be displayed for approximately 5 seconds
when a system fault is detected, and a chime
will sound. If the ignition switch is cycled, this
sequence will repeat, providing the system fault
still exists. The Tire Pressure Monitoring Telltale
Light will turn off when the fault condition no
longer exists. A system fault can occur by any of
the following:
1. Jamming due to electronic devices or driving
next to facilities emitting the same Radio Fre-
quencies as the TPM sensors.
2. Installing some form of aftermarket window
tinting that affects radio wave signals.
3. Lots of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM
sensors.NOTE:There is no tire pressure monitoring sensor in
the spare tire. The TPMS will not be able to
monitor the tire pressure. If you install the
spare tire, in place of a road tire, that has a
pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a
chime will sound, a “LOW TIRE PRESSURE”
message will be displayed in the instrument
cluster for a minimum of five seconds, an
Inflate to XXX
message will be displayed and
the Tire Pressure Monitoring Telltale Light will
turn ON. After driving the vehicle for up to 20
minutes above 15 mph (24 km/h), the Tire
Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and then remain on
solid. In addition, a “SERVICE TPM SYSTEM”
message will be displayed for a minimum of
five seconds. For each subsequent ignition
switch cycle, a chime will sound, a “SERVICE
TPM SYSTEM” message will be displayed for
a minimum of five seconds, and the Tire Pres-
sure Monitoring Telltale Light will flash on and
off for 75 seconds and then remain on solid. Once you repair or replace the original road
tire, and reinstall it on the vehicle in place of
the spare tire, the TPMS will update automati-
cally and the Tire Pressure Monitoring Telltale
Light will turn OFF, 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 for the TPMS to
receive this information.
Premium System – If EquippedThe Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire pres-
sure levels. Sensors, mounted to each wheel as
part of the valve stem, transmit tire pressure
readings to the Receiver Module.
NOTE:
It is particularly important, for you to regu-
larly check the tire pressure in all of your

269

The Tire Pressure Monitor System (TPMS) con-
sists of the following components:
•Receiver Module
• Four Tire Pressure Monitoring Sensors
•
Various Tire Pressure Monitoring System Mes-
sages, which display in the Electronic Vehicle
Information Center (EVIC), and a graphic dis-
playing tire pressures
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring Telltale
Light will illuminate in the instrument
cluster, and an audible chime will be
activated, when one or more of the four
active road tire pressures are low. In addition, the
EVIC will display a “LOW TIRE PRESSURE”
message for a minimum of five seconds, an
"Inflate to XXX" message and a graphic display of
the pressure value(s) with the low tire(s) “flash- ing.” Refer to “Electronic Vehicle Information Cen-
ter (EVIC)” in “Understanding Your Instrument
Panel” for further information.
NOTE:
Your system can be set to display pressure
units in PSI, kPa, or BAR.
Should a low tire condition occur on any of the
four active road tire(s), you should stop as soon
as possible, and inflate the low tire(s) that is
“flashing” on the graphic display to the vehicle’s
recommended cold tire pressure displayed inthe
"Inflate to XXX" message. The system will
automatically update, the graphic display of the
pressure value(s) will stop “flashing,” and the
Tire Pressure Monitoring Telltale Light will extin-
guish once the updated tire pressure(s) 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.
SERVICE TPM SYSTEM Warning
The Tire Pressure Monitoring Telltale Light will
flash on and off for 75 seconds, and remain on
solid when a system fault is detected. The
system fault will also sound a chime. The EVIC
will display a “SERVICE TPM SYSTEM” mes-
sage for a minimum of five seconds. This mes-
sage is then followed by a graphic display, with
“- -“ in place of the pressure value(s), indicating
which Tire Pressure Monitoring Sensor(s) is not
being received.
NOTE:
Your system can be set to display pressure
units in PSI or kPa.
