SAFETY 101
Electronic Roll Mitigation (ERM)
Electronic Roll Mitigation (ERM) 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 vehicle’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 maneuvers; it cannot
prevent wheel lift due to other factors, such as road
conditions, leaving the roadway, or striking objects or other
vehicles.Hill Start Assist (HSA)
Hill Start Assist (HSA) is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain the
level of brake pressure the driver applied for a short period
of time after the driver takes their foot off of the brake pedal.
If the driver does not apply the throttle during this short
period of time, the system will release brake pressure and the
vehicle will roll down the hill. The system will release brake
pressure in proportion to the amount of throttle applied as
the vehicle starts to move in the intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
• The vehicle must be stopped.
• The vehicle must be on a 5% (approximate) grade or
greater hill.
• Gear selection matches vehicle uphill direction (i.e., vehicle facing uphill is in forward gear; vehicle backing
uphill is in REVERSE (R) gear).

HSA will work in REVERSE and all forward gears when the
activation criteria have been met. The system will not activate if
the vehicle is placed in NEUTRAL (N) or PARK (P).

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.

102 SAFETY
Traction Control System (TCS)
The Traction Control System (TCS) monitors the amount of
wheel spin of each of the driven wheels. If wheel spin is
detected, brake pressure is applied to the slipping wheel(s)
and engine power is reduced to provide enhanced accelera-
tion and stability. A feature of the TCS system, Brake Limited
Differential (BLD), functions similar to a limited slip differ -
ential and 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 mode. Refer to “Electronic Stability
Control (ESC)” in this section for further information. Trailer Sway Control (TSC) — If Equipped
Trailer Sway Control (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 appro
-
priate wheel(s) to counteract the sway of the trailer. TSC will
become active automatically once an excessively swaying
trailer is recognized.
NOTE:
TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations. 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” mode.
WARNING!
There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer, when the system will
not activate and slight rolling may occur. This could
cause a collision with another vehicle or object. Always
remember the driver is responsible for braking the
vehicle.
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.

Air Bag Warning Light
The Occupant Restraint Controller (ORC) monitors the
readiness of the electronic parts of the air bag system
whenever the ignition switch is in the AVV/START or
MAR/ACC/ON/RUN position. If the ignition switch is in the
STOP/OFF/LOCK position the air bag system is not on and the air
bags will not inflate.

The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power or
it becomes disconnected prior to deployment.

The ORC turns on the Air Bag Warning Light in the instrument
panel for approximately four to eight seconds for a self-check when
the ignition switch is in the MAR/ACC/ON/RUN position. After
the self-check, the Air Bag Warning Light will turn off. If the ORC
detects a malfunction in any part of the system, it turns on the Air
Bag Warning Light, either momentarily or continuously. A single
chime will sound to alert you if the light comes on again after initial
startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The diagnostics
also record the nature of the malfunction. While the air bag
system is designed to be maintenance free, if any of the
following occurs, have an authorized dealer service the air
bag system immediately.
• The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in the
MAR/ACC/ON/RUN position.
• The Air Bag Warning Light remains on after the four to eight-second interval.
• The Air Bag Warning Light comes on intermittently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any engine related gauges
are not working, the Occupant Restraint Controller (ORC)
may also be disabled. In this condition the air bags may not
be ready to inflate for your protection. Have an authorized
dealer service the air bag system immediately.

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 instru -
ment 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 properly if modifications are made. Take your
vehicle to an authorized dealer for any air bag system
service. If your seat, including your trim cover and
cushion, needs to be serviced in any way (including
removal or loosening/tightening of seat attachment
bolts), take the vehicle to an authorized dealer. Only
manufacturer approved seat accessories may be used. If
it is necessary to modify the air bag system for persons
with disabilities, contact an authorized dealer.

SAFETY 153
Transporting Pets
Air Bags deploying in the front seat could harm your pet. An
unrestrained pet will be thrown about and possibly injured,
or injure a passenger during panic braking or in a collision.
Pets should be restrained in the rear seat (if equipped) in pet
harnesses or pet carriers that are secured by seat belts.
SAFETY TIPS
Transporting Passengers

NEVER TRANSPORT PASSENGERS IN THE CARGO AREA.

Exhaust Gas
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
WARNING!
• Do not leave children or animals inside parked vehicles in hot weather. Interior heat build-up may cause
serious injury or death.

• It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these
areas are more likely to be seriously injured or killed.

• Do not allow people to ride in any area of your vehicle that is not equipped with seats and seat belts.
• Be sure everyone in your vehicle is in a seat and using a seat belt properly.
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/liftgate/rear doors open, make sure that all windows 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.

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
accelerator, 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 interfere with the accelerator, brake, or
clutch pedals and cause a loss of vehicle control. To
prevent SERIOUS INJURY or DEATH:
• ALWAYS securely attach your floor mat using the floor mat fasteners. DO NOT install your floor mat
upside down or turn your floor mat over. Lightly pull to
confirm mat is secured using the floor mat fasteners on
a regular basis.
• ALWAYS REMOVE THE EXISTING FLOOR MAT FROM THE VEHICLE before installing any other
floor mat. NEVER install or stack an additional floor
mat on top of an existing floor mat.
• ONLY install floor mats designed to fit your vehicle.NEVER install a floor mat that cannot be properly
attached and secured to your vehicle. If a floor mat
needs to be replaced, only use a FCA approved floor
mat for the specific make, model, and year of your
vehicle.
• ONLY use the driver’s side floor mat on the driver’s side floor area. To check for interference, with the
vehicle properly parked with the engine off, fully
depress the accelerator, the brake, and the clutch pedal
(if present) to check for interference. If your floor mat
interferes with the operation of any pedal, or is not
secure to the floor, remove the floor mat from the
vehicle and place the floor mat in your trunk.
• ONLY use the passenger’s side floor mat on the passenger’s side floor area.
• ALWAYS make sure objects cannot fall or slide into the driver’s side floor area when the vehicle is moving.

STARTING AND OPERATING
STARTING THE ENGINE
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
Automatic Transmission
The gear selector must be in the PARK (P) or NEUTRAL (N)
position before you can start the engine. Press the brake
pedal before shifting to any driving gear.
NOTE:
You must press the brake pedal before shifting out of PARK.
Normal Starting
NOTE:
Normal starting of either a cold or a warm engine is obtained
without pumping or pressing the accelerator pedal.
Turn the ignition switch to the AVV (START) position and
release it when the engine starts. If the engine fails to start
within 10 seconds, turn the ignition switch to the STOP
(OFF/LOCK) position, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
WARNING!
• Never leave children alone in a vehicle, or with access to an unlocked vehicle.
• Allowing children to be in a vehicle unattended is dangerous for a number of reasons. A child or others
could be seriously or fatally injured. Children should
be warned not to touch the parking brake, brake pedal
or the transmission gear selector.
• Do not leave the key fob in or near the vehicle (or in a location accessible to children). A child could operate
power windows, other controls, or move the vehicle.

158 STARTING AND OPERATING
Cold Weather Operation
To ensure reliable starting at low temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
To prevent possible engine damage while starting at low
temperatures, this vehicle will inhibit engine cranking when
the ambient temperature is less than -31°F (-35° C) and the oil
temperature sensor reading indicates an engine block heater
has not been used. The message “plug in engine heater” will
be displayed in the instrument cluster when the ambient
temperature is below -25°F (-32° C) at the time the engine is
shut off as a reminder.
Extended Park Starting
NOTE:
Extended Park condition occurs when the vehicle has not
been started or driven for at least 30 days.
1. Install a battery charger or jumper cables to the battery toensure a full battery charge during the crank cycle.
2. Cycle the ignition to the AVV/”START” position and release it when the engine starts. 3. If the engine fails to start within ten seconds, cycle the
ignition to the STOP (OFF/LOCK) position, wait five
seconds to allow the starter to cool, then repeat the
Extended Park Starting procedure.
4. If the engine fails to start after eight attempts, allow the starter to cool for at least 10 minutes, then repeat the
procedure.
If Engine Fails To Start

If the engine fails to start after you have followed the "Normal
Starting" or "Extreme Cold Weather" procedure, and has not
experienced an extended park condition as identified in
"Extended Park Starting" procedure it may be flooded. Push
the accelerator pedal all the way to the floor and hold it there.
Crank the engine for no more than 15 seconds. This should
clear any excess fuel in case the engine is flooded. Leave the
ignition key in the MAR position, release the accelerator pedal
and repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a time. Wait 10
to 15 seconds before trying again.

STARTING AND OPERATING 159
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine and permits
quicker starts in cold weather.
Connect the cord to a 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
For ambient temperatures below 0°F (-18°C), the engine
block heater is recommended. For ambient temperatures
below -20°F (-29°C), the engine block heater is required.
The engine block heater cord is routed under the hood,
behind to the driver’s side headlamp. Follow the steps below
to properly use the engine block heater:
1. Locate the engine block heater cord (behind the driver’sside headlamp).
2. Undo the hook-and-loop strap that secures the heater cord in place.
WARNING!
• Never pour fuel or other flammable liquid into the throttle body air inlet opening in an attempt to start the
vehicle. This could result in flash fire causing serious
personal injury.
• Do not attempt to push or tow your vehicle to get it started. Vehicles equipped with an automatic
transmission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the engine
has started, ignite and damage the converter and
vehicle.
• If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or
the battery in another vehicle. This type of start can be
dangerous if done improperly. Refer to “Jump Starting
Procedure” in “In Case Of Emergency” for further
information.
CAUTION!
To prevent damage to the starter, do not continuously
crank the engine for more than 25 seconds at a time. Wait
60 seconds before trying again.
