2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more
than one-half turn to the left.
6. Push the “ESC Off” button located in the
lower switch bank below the climate con-
trol four times within 20 seconds. The
“ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center
and then an additional slightly more than
one-half turn to the right.
8. Turn the ignition to the OFF mode and
then back to ON. If the sequence was
completed properly, the “ESC Off Indica-
tor Light” will blink several times to con-
firm HSA is disabled.
9. Repeat these steps if you want to return
this feature to its previous setting.Towing With HSA
HSA will also provide assistance to mitigate
roll back while towing a trailer.
WARNING!
• If you use a trailer brake controller with
your trailer, the trailer brakes may be
activated and deactivated with the brake
switch. If so, there may not be enough
brake pressure to hold both the vehicle
and the trailer on a hill when the brake
pedal is released. In order to avoid roll-
ing down an incline while resuming ac-
celeration, manually activate the trailer
brake or apply more vehicle brake pres-
sure prior to releasing the brake pedal.
• HSA is not a parking brake. Always apply
the parking brake fully when exiting your
vehicle. Also, be certain to place the
transmission in PARK.
• Failure to follow these warnings can re-
sult in a collision or serious personal
injury.
Traction Control System (TCS)
This system monitors the amount of wheel
spin of each of the driven wheels. If wheel
spin is detected, the TCS may apply brake
pressure to the spinning wheel(s) and/or re-
duce engine power to provide enhanced ac-
celeration and stability. A feature of the TCS,
Brake Limited Differential (BLD), functions
similar to a limited slip differential and con-
trols 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. BLD may remain en-
abled even if TCS and ESC are in a reduced
mode.
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(s) to assist in
counteracting the oversteer or understeer
condition. Engine power may also be reduced
to help the vehicle maintain the desired path.
SAFETY

should be used for most driving conditions.
Alternate ESC modes should only be used 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. This mode may modify TCS and ESC
thresholds for activation, which allows for
more wheel spin than normally allowed. This
mode may be useful if the vehicle becomes
stuck.
To enter the “Partial Off” mode, momentarily
push the “ESC Off” switch and the “ESC Off
Indicator Light” will illuminate. To turn the
ESC on again, momentarily push the “ESC
Off” switch and the “ESC Off Indicator Light”
will turn off.
NOTE:
For vehicles with multiple partial ESC modes
a momentary button push will toggle the ESC
mode. Multiple momentary button pushed
may be required to return to ESC On.WARNING!
• When in “Partial Off” mode, the TCS
functionality of ESC, (except for the lim-
ited slip feature described in the TCS
section), has been disabled and the
“ESC Off Indicator Light” will be illumi-
nated. When in “Partial Off” mode, the
engine power reduction feature of TCS is
disabled, and the enhanced vehicle sta-
bility offered by the ESC system is re-
duced.
• Trailer Sway control (TSC) is disabled
when the ESC system is in the “Partial
Off” mode.
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, TCS and
ESC features are turned OFF. To enter the
“Full Off” mode, push 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 in-
strument cluster. To turn ESC ON again,
momentarily push the “ESC Off” switch.
NOTE:
System may switch from ESC “Full Off” to
“Partial Off” mode when vehicle exceeds a
predetermined speed. When the vehicle
speed slows below the predetermined speed
the system will return to ESC “Full Off”.
ESC modes may also be affected by drive
modes if so equipped.
WARNING!
• In the ESC “Full Off” mode, the engine
torque reduction and stability features
are disabled. Therefore, enhanced ve-
hicle stability offered by the ESC system
is unavailable. In an emergency evasive
maneuver, the ESC system will not en-
gage to assist in maintaining stability.
ESC “Full Off” mode is intended for
off-highway or off-road use only.
• With the ESC switched off, the en-
hanced vehicle stability offered by ESC
is unavailable. In an emergency evasive
SAFETY
82

WARNING!
maneuver, the ESC system will not en-
gage to assist in maintaining stability.
ESC “Full Off” mode is only intended for
off-highway or off-road use.
• The Electronic Stability Control (ESC)
cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it
increase the traction afforded by prevail-
ing road conditions. ESC cannot prevent
all accidents, including those resulting
from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
ESC also cannot prevent collisions.
ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The “ESC Activation/Malfunction
Indicator Light” in the instrument
cluster will come on when the
ignition is turned to the ON mode.
It should go out with the engine
running. If the “ESC Activation/Malfunction
Indicator Light” comes on continuously withthe engine running, a malfunction has been
detected in the ESC system. If this light
remains on after several ignition cycles, and
the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph
(48 km/h), see an authorized dealer as soon
as possible to have the problem diagnosed
and corrected.
The “ESC Activation/Malfunction Indicator
Light” (located in the instrument cluster)
starts to flash as soon as the tires lose trac-
tion 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 con-
ditions.
NOTE:
• The “ESC Activation/Malfunction Indicator
Light” and the “ESC OFF Indicator Light”
come on momentarily each time the igni-
tion is turned ON.• Each time the ignition is turned ON, the
ESC system will be on even if it was turned
off previously.
• The ESC system will make buzzing or click-
ing sounds when it is active. This is normal;
the sounds will stop when ESC becomes
inactive following the maneuver that
caused the ESC activation.
The “ESC OFF Indicator Light” indi-
cates the customer has elected to
have the Electronic Stability Control
(ESC) in a reduced mode.
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 steering wheel angle and vehi-
cle’s speed are sufficient 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 can only reduce the chance of wheel lift
occurring during severe or evasive driving
83

maneuvers; it cannot prevent wheel lift due
to other factors, such as road conditions,
leaving the roadway, or striking objects or
other vehicles.
NOTE:
ERM is disabled anytime the ESC is in “Full
Off” mode (if equipped). Refer to “Electronic
Stability Control (ESC)” in this section for a
complete explanation of the available ESC
modes.
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 roll overs, especially those
that involve leaving 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.
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. TSC will become active automatically
once an excessively swaying trailer is recog-
nized.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions. Refer to “Trailer Towing” in “Starting
And Operating” for further information.
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 swaying. TSC is disabled when
the ESC system is in the “Partial Off” or “Full
Off” modes.WARNING!
If TSC activates while driving, slow the
vehicle down, stop at the nearest safe
location, and adjust the trailer load to
eliminate trailer sway.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time
required to reach full braking during emer-
gency braking situations. It anticipates 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 periodi-
cally apply a small amount of brake pressure
to remove any water buildup on the front
brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When
Rain Brake Support is active, there is no
notification to the driver and no driver inter-
action is required.

However, if you haven’t healed significantly
within a few days, or if you have any blis-
tering, see your doctor immediately.
• As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that gen-
erates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area
with cool water. For nose or throat irritation,
move to fresh air. If the irritation continues,
see your doctor. If these particles settle on
your clothing, follow the garment manufac-
turer’s instructions for cleaning.
Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.

dealer immediately. Also, have the Occu-
pant Restraint Controller System serviced
as well.
NOTE:
• Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
• After any collision, the vehicle should be
taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communica-
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the ORC will determine whether to
have the Enhanced Accident Response Sys-
tem perform the following functions:
• Cut off fuel to the engine (If Equipped)
• Cut off battery power to the electric motor
(If Equipped)
• Flash hazard lights as long as the battery
has power• Turn on the interior lights, which remain on
as long as the battery has power or for 15
minutes from the intervention of the En-
hanced Accident Response System.
• Unlock the power door locks.
Your vehicle may also be designed to perform
any of these other functions in response to
the Enhanced Accident Response System:
• Turn off the Fuel Filter Heater, Turn off the
HVAC Blower Motor, Close the HVAC Circu-
lation Door
• Cut off battery power to the:
– Engine
– Electric Motor (if equipped)
– Electric power steering
– Brake booster
– Electric park brake
– Automatic transmission gear selector
– Horn
– Front wiper
– Headlamp washer pump
NOTE:
After an accident, remember to cycle the
ignition to the STOP (OFF/LOCK) position
and remove the key from the ignition switch

to avoid draining the battery. Carefully check
the vehicle for fuel leaks in the engine com-
partment and on the ground near the engine
compartment and fuel tank before resetting
the system and starting the engine. If there
are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the system by following the
procedure described below. If you have any
doubt, contact an authorized dealer.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Re-
sponse System functions after an event, the
ignition switch must be changed from igni-
tion START or ON/RUN to ignition OFF. Care-
fully check the vehicle for fuel leaks in the
engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine.
Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bag
system could cause it to fail when you
need it. You could be injured if the air
bag system is not there to protect you.
Do not modify the components or wiring,
including adding any kind of badges or
stickers to the steering wheel hub trim
cover or the upper passenger side of the
instrument panel. Do not modify the
front bumper, vehicle body structure, or
add aftermarket side steps or running
boards.
• It is dangerous to try to repair any part of
the air bag system yourself. Be sure to
tell anyone who works on your vehicle
that it has an air bag system.
• Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function prop-
erly if modifications are made. Take your
vehicle to an authorized dealer for any
air bag system service. If your seat, in-
cluding your trim cover and cushion,
WARNING!
needs to be serviced in any way (includ-
ing removal or loosening/tightening of
seat attachment bolts), take the vehicle
to an authorized dealer. Only manufac-
turer approved seat accessories may be
used. If it is necessary to modify the air
bag system for persons with disabilities,
contact an authorized dealer.
Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-
like situations, such as an air bag deployment
or hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems
performed. The EDR is designed to record
data related to vehicle dynamics and safety
systems for a short period of time, typically
30 seconds or less. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were
operating;

Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies
must be replaced after a collision if they have
been damaged (i.e., bent retractor, torn web-
bing, etc.). If there is any question regarding
seat belt or retractor condition, replace the
seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for
four to eight seconds as a bulb check when
the ignition switch is first turned to ON/RUN.
If the light is either not on during starting,
stays on, or turns on while driving, have the
system inspected at an authorized dealer as
soon as possible. After the bulb check, this
light will illuminate with a single chime when
a fault with the Air Bag System has been
detected. It will stay on until the fault is
removed. If the light comes on intermittently
or remains on while driving, have an autho-
rized dealer service the vehicle immediately.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
Defroster
Check operation by selecting the defrost
mode and place the blower control on high
speed. You should be able to feel the air
directed against the windshield. See an au-
thorized dealer for service if your defroster is
inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your
vehicle. Only use a floor mat that does not
interfere with the operation of the accelera-
tor, brake or clutch pedals. Only use a floor
mat that is securely attached using the floor
mat fasteners so it cannot slip out of position
and interfere with the accelerator, brake or
clutch pedals or impair safe operation of your
vehicle in other ways.
WARNING!
An improperly attached, damaged, folded,
or stacked floor mat, or damaged floor mat
fasteners may cause your floor mat to in-
terfere with the accelerator, brake, or
clutch pedals and cause a loss of vehicle

Normal Starting Procedure — Keyless
Enter-N-Go
Observe the instrument panel cluster lights
when starting the engine.
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal.
1. Always apply the parking brake.
2. Press and hold the brake pedal while
pushing the ENGINE START/STOP button
once.
NOTE:
A delay of the start of up to five seconds is
possible under very cold conditions. The
“Wait to Start” telltale will be illuminated
during the pre-heat process, When the
engine Wait To Start light goes off the
engine will automatically crank.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START the engine be-
CAUTION!
fore the water is drained from the fuel
filters to avoid engine damage.
3. The system will automatically engage the
starter to crank the engine. If the vehicle
fails to start, the starter will disengage
automatically after 30 seconds.
4. If you wish to stop the cranking of the
engine prior to the engine starting, push
the button again.
5. Check that the oil pressure warning light
has turned off.
6. Release the parking brake.
Engine Warm Up
Avoid full throttle operation when the engine
is cold. When starting a cold engine, bring the
engine up to operating speed slowly to allow
the oil pressure to stabilize as the engine
warms up.NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,200 RPM during the
warm-up period, especially in cold ambient
temperature conditions.
ENGINE BREAK-IN
RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle)
in your vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable.
While cruising, brief full-throttle acceleration
within the limits of local traffic laws contrib-
utes to a good break-in. Wide-open throttle
acceleration in low gear can be detrimental
and should be avoided.
