displayed in the instrument cluster, along with a high-
lighted#M#(Manual) indication. When the shift lever is
in the MANUAL (M) position, tap the shift lever forward
(-) (or tap the (-) shift paddle on the steering wheel, if
equipped) to downshift the transmission to the next
lower gear, or tap the lever rearward (+) (or tap the (+)
shift paddle, if equipped) to command an upshift.
NOTE:Tapping one of the steering wheel-mounted shift
paddles (+/-), if equipped, while the shift lever is in
DRIVE, will activate a temporary AutoStick® mode.
Tapping (-) to enter AutoStick® mode will downshift the
transmission to the next lower gear, while using (+) to
enter AutoStick® mode will retain the current gear. The
current gear will be displayed in the instrument cluster,
but the#M#will not be highlighted. The transmission will
revert back to normal operation (if the shift lever remains
in DRIVE) after a period of time, depending on accelera-
tor pedal activity.
In AutoStick® mode, the transmission will shift up or
down when (+/-) is manually selected by the driver
(using the shift lever, or the shift paddles [if equipped]),
unless an engine lugging or overspeed condition would
result. It will remain in the selected gear until another
upshift or downshift is chosen, except as described
below.
•In temporary AutoStick® mode (shift lever in DRIVE),
the transmission will automatically shift up when
maximum engine speed is reached. If the accelerator is
fully depressed, the transmission will downshift when
possible (based on current vehicle speed and gear).
Lack of accelerator pedal activity will cause the trans-
mission to revert to automatic operation.
•If normal AutoStick® mode is engaged (shift lever in
MANUAL position), manual gear selection will be
maintained until the shift lever is returned to DRIVE,
or as described below. The transmission will not

WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
SPORT MODE — WITHOUT PERFORMANCE
CONTROL
Your vehicle is equipped with a Sport Mode feature. This
mode is a configuration set up for typical enthusiast
driving. The engine, transmission (when equipped with
automatic transmission), and steering systems are all set
to their SPORT settings. Sport Mode will provide im-
proved throttle response and modified shifting for an
enhanced driving experience, as well the greatest amount
of steering feel. This mode may be activated and deacti-
vated by pressing the Sport button on the instrument
panel switch bank.
For vehicles equipped with Drive Modes, Refer to “Per-
formance Control — If Equipped” within “Uconnect
Settings” in “Understanding Your Instrument Panel”
chapter for further information.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery 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.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear

wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when the roads are
slushy.
2. Slow down if the road has standing water or puddles.
3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain sufficient distance between your vehicle and
the vehicle in front of you to avoid a collision in a
sudden stop.
Your vehicle may be equipped with a Limited Slip
Differential (LSD) that reduces, but does not eliminate,
the amount of wheel slip across a given axle for im-
proved handling.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.

STARTING AND OPERATING 373

When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. For vehicles equipped
with an automatic transmission, apply the parking brake
before placing the shift lever in PARK, otherwise the load
on the transmission locking mechanism may make it
difficult to move the shift lever out of PARK. The parking
brake should always be applied whenever the driver is
not in the vehicle.
Manual Transmission — If Equipped
The foot operated parking brake is positioned below the
lower left corner of the instrument panel. To release the
parking brake, pull the parking brake release handle.

System), and the ESC (Electronic Stability Control). These
systems work together to enhance both vehicle stability
and control in various driving conditions.
An additional electronic brake control feature called Hill
Start Assist (HSA) is standard on all models.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
braking conditions. The system automatically “pumps”
the brakes during severe braking conditions to prevent
wheel lock-up.
The Electronic Brake Force Distribution (EBD) prevents the
rear wheels from over-braking and provides greater control
of available braking forces applied to the rear axle.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self check cycle to ensure that the ABS system
is working properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You also may experience the following when the brake
system goes into anti-lock:
•The ABS motor running (it may continue to run for a
short time after the stop)
•The clicking sound of solenoid valves
•Brake pedal pulsations
•A slight drop or fall away of the brake pedal at the end
of the stop
These are all normal characteristics of ABS.
382 STARTING AND OPERATING

WARNING!
•The Anti-Lock Brake System (ABS) contains so-
phisticated electronic equipment that may be sus-
ceptible to interference caused by improperly in-
stalled or high output radio transmitting
equipment. This interference can cause possible
loss of anti-lock braking capability. Installation of
such equipment should be performed by qualified
professionals.
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
(Continued)
WARNING!(Continued)
•The Anti-Lock Brake System (ABS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase braking or steering
efficiency beyond that afforded by the condition of
the vehicle brakes and tires or the traction afforded.
•The Anti-Lock Brake System (ABS) cannot prevent
collisions, including those resulting from excessive
speed in turns, following another vehicle too
closely, or hydroplaning.
•The capabilities of an Anti-Lock Brake System
(ABS) equipped vehicle must never be exploited in
a reckless or dangerous manner, that could jeopar-
dize the user’s safety or the safety of others.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.

STARTING AND OPERATING 383

Anti-Lock Brake Warning Light
The “Anti-Lock Brake System (ABS) Warning
Light” monitors the Anti-Lock Brake System. The
light will come on when the ignition switch is
turned to the ON position and may stay on for as long as
four seconds.
If the “ABS Warning Light” remains on or comes on
while driving, it indicates that the anti-lock portion of the
brake system is not functioning and that service is
required. However, the conventional brake system will
continue to operate normally if the “Brake Warning
Light” is not on.
If the “ABS Warning Light” is on, the brake system
should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “ABS Warning Light”
does not come on when the ignition switch is turned to
the ON position, have the bulb repaired as soon as
possible.
If both the “Brake Warning Light” and the “ABS Warning
Light” remain on, the ABS and EBD systems are not
functioning. Immediate repair to the ABS system is
required.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each
driven wheel. If wheel spin is detected, brake pressure is
applied to the slipping wheel(s) and engine power is
reduced to provide enhanced acceleration and stability.
A feature of the TCS system, Brake Limited Differential
(BLD), controls the wheel spin across a driven axle. If one
wheel on a driven axle is spinning faster than the other,
the system will apply the brake of the spinning wheel.
This will allow more engine torque to be applied to the
wheel that is not spinning. This feature remains active
even if TCS and ESC are in the “Partial Off” or#Full Off#
mode. Refer to “Electronic Stability Control (ESC)” in this
section for more information.

by applying the brake of the appropriate wheel. Engine
power may also be reduced to assist in counteracting the
condition of oversteer or understeer and help the vehicle
maintain the desired path.
The ESC uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESC applies the
brake of the appropriate wheel to assist in counteracting
the condition of oversteer or understeer.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
WARNING!
The Electronic Stability Control System (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
all accidents, including those resulting from exces-
sive speed in turns, driving on very slippery surfaces,
or hydroplaning. ESC also cannot prevent accidents
resulting from loss of vehicle control due to inappro-
priate driver input for the conditions. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities 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.

STARTING AND OPERATING 387

ESC Operating Modes
The ESC system has two or three available operating
modes:
ESC On
This is the normal operating mode for the ESC. When-
ever the vehicle is started, the ESC system will be in this
mode. This mode should be used for most driving
situations. The ESC should only be turned OFF for
specific reasons as noted in the following paragraphs.
Partial Off
The “Partial Off” mode is intended for times when a
more spirited driving experience is desired. It is also
intended for driving in deep snow, sand, or gravel. This
mode disables the TCS portion of the ESC and raises the
threshold for ESC activation, which allows for more
wheel spin than what ESC normally allows. The “ESC
Off” switch is located in the switch bank near the bottom
center of the instrument panel or in the touchscreen radio
. To enter the “Partial Off” mode, momentarily press the
“ESC Off” switch and the “ESC Off Indicator Light” will
illuminate. To turn the ESC ON again, momentarily press
the “ESC Off” switch and the “ESC Off Indicator Light”
will turn off.
NOTE:To improve the vehicle’s traction when driving
with snow chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the
“Partial Off” mode by momentarily pressing the “ESC
Off” switch. Once the situation requiring “Partial Off”
mode is overcome, turn the ESC ON again by momen-
tarily pressing the “ESC Off” switch. This may be done
while the vehicle is in motion.
388 STARTING AND OPERATING

WARNING!
When in “Partial Off” mode, the TCS portion of ESC,
except for the limited wheel spin feature described in
the TCS section, has been disabled and the “ESC Off
Indicator Light” will be illuminated. When in “Par-
tial Off” mode, the enhanced vehicle stability offered
by the ESC system is reduced.
Full Off — If Equipped
This mode is intended for off-highway or off-road use
only and should not be used on any public roadways. In
this mode, all TCS and ESC stability features are turned
OFF. To enter the “Full Off” mode, press and hold the
“ESC Off” switch for five seconds while the vehicle is
stopped with the engine running. After five seconds, a
chime will sound, the “ESC OFF Indicator Light” will
illuminate, and the “ESC Off” message will display in the
vehicle odometer. The “ESC off” message may appear in
the Driver Information Display (DID). Refer to “Driver
Information Display (DID)” in “Understanding Your
Instrument Panel” for further information. To turn ESC
ON again, momentarily press the “ESC Off” switch.
NOTE:The#ESC off#message will display and the
audible chime will sound when the shift lever is moved
into the PARK position from any position other than
PARK and then moved out of the PARK position. This
will occur when the message was previously cleared.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled. There-
fore, the enhanced vehicle stability offered by ESC is
unavailable. In an emergency evasive maneuver, the
ESC system will not engage to assist in maintaining
stability.$ESC Off$mode is intended for off-highway
or off-road use only.
