Adaptive Cruise Control (ACC) Operation
The speed control buttons (located on the right side of the
steering wheel) operates the ACC system.NOTE:
Any chassis/suspension or tire size modifications
to the vehicle will effect the performance of the Adaptive
Cruise Control and Forward Collision Warning System.
Activating Adaptive Cruise Control (ACC)
You can only engage ACC if the vehicle speed is above
0 mph (0 km/h).
The minimum set speed for the ACC system is 20 mph
(32 km/h).
When the system is turned on and in the ready state, the
instrument cluster display will read “ACC Ready.”
When the system is off, the instrument cluster display will
read “Adaptive Cruise Control (ACC) Off.”
NOTE: You cannot engage ACC under the following con-
ditions:
• When you apply the brakes.
• When the parking brake is set.
• When the automatic transmission is in PARK, REVERSE
or NEUTRAL.
• When the vehicle speed is outside of the speed range.
• When the brakes are overheated.

Tire Pressure Monitoring System (TPMS) Warning Light
Yellow TelltaleLight What It Means
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 above, the display will show the indica-
tions corresponding to each tire in sequence.
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. Repair immedi-
ately using the dedicated tire repair kit and contact
your authorized dealer as soon as possible.
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 tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, 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 signifi-
cantly 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.
218 UNDERSTANDING YOUR INSTRUMENT PANEL

Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to main-
tain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunc-
tion 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 afterreplacing 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.
CAUTION!
The TPMS has been optimized for the original equip-
ment 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 equip-
ment 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 inoper-
able. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho-
rized dealer to have your sensor function checked.4

ALL-WHEEL DRIVE (AWD) — IF EQUIPPED
This vehicle is equipped with an active on-demand All-
Wheel Drive (AWD) system which makes available opti-
mum traction for a wide variety of road surface and
driving conditions. The system minimizes wheel slip by
automatically redirecting torque to the front and rear
wheels as necessary.
To maximize fuel economy, your AWD vehicle automati-
cally defaults to rear-wheel drive (RWD) when road and
environmental conditions are such that wheel slip is un-
likely to occur. When specific road and environmental
conditions require increased levels of road traction, the
vehicle automatically shifts into AWD mode. Automatic
AWD operation could be activated by outside temperature,
wheel slip, or other predetermined conditions (there may
be a slight delay for AWD engagement after a wheel slip
condition occurs). AWD can also be manually selected by
activating AutoStick mode (+/-), engaging Sport Mode or
activating the windshield wipers for an extended period of
time. Drive mode, RWD or AWD, can be found in the
instrument cluster display. Refer to “Instrument Cluster
Display” in “Understanding Your Instrument Panel” for
further information.NOTE:
If the “SERVICE AWD SYSTEM” warning message
appears after engine start up, or during driving, it means
that the AWD system is not functioning properly and that
service is required. Refer to “Instrument Cluster Display”
in “Understanding Your Instrument Panel” for further
information.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire size
may cause failure of the front differential and/or the
transfer case.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the rear (driving)
wheels.
312 STARTING AND OPERATING

ESC system becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes when the 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.
WARNING!
•Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capa-
bilities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user ’s safety or the safety of
others.
(Continued)
WARNING! (Continued)
•Vehicle modifications, or failure to properly main-
tain your vehicle, may change the handling charac-
teristics of your vehicle, and may negatively affect
the performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly
worn tires may also degrade ESC performance. Any
vehicle modification or poor vehicle maintenance
that reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.
ESC Operating Modes
NOTE: Depending upon model and mode of operation, the
ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions.
Alternate ESC modes should only be used for specific
reasons as noted in the following paragraphs.
324 STARTING AND OPERATING

Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to reach
full braking during emergency braking situations. It antici-
pates when an emergency braking situation may occur by
monitoring how fast the throttle is released by the driver.
The EBC will prepare the brake system for a panic stop.
Rain Brake Support (RBS)
Rain Brake Support may improve braking performance in
wet conditions. It will periodically apply a small amount of
brake pressure to remove any water buildup on the front
brake rotors. It functions when the windshield wipers are
in LO or HI speed. When Rain Brake Support is active,
there is no notification to the driver and no driver interac-
tion is required.
