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
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This system
includes Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Electronic Brake Force
Distribution (EBD), Electronic Roll Mitigation
(ERM), Electronic Stability Control (ESC), Hill Start
Assist (HSA), and Traction Control System (TCS).
These systems work together to enhance both
vehicle stability and control in various driving
conditions.
Your vehicle may also be equipped with Rain Brake
Support (RBS), Ready Alert Braking (RAB),
Selec-Speed Control (SSC), and Trailer Sway
Control (TSC).
Brake System Warning Light
The red Brake System Warning Light will turn on
when the ignition is placed in the ON/RUN mode,
and may stay on for as long as four seconds. If the Brake System Warning Light remains on or
comes on while driving, it indicates that the brake
system is not functioning properly and that
immediate service is required. If the Brake System
Warning Light does not come on when the ignition
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and amount
of brake application, and then applies optimum
pressure to the brakes. This can help reduce
braking distances. The BAS complements the
Anti-Lock Brake System (ABS) by applying the
brakes very quickly, creating the most efficient
braking assistance possible. To receive the benefit
of the system, you must apply continuous braking
pressure during the stopping sequence (do not
“pump” the brakes). Do not reduce brake pedal
pressure unless braking is no longer desired. Once
the brake pedal is released, the BAS is
deactivated.
Electronic Brake Force Distribution (EBD)
The EBD function manages the distribution of the
braking torque between the front and rear axles by
limiting braking pressure to the rear axle. This is
done to prevent overslip of the rear wheels to avoid
vehicle instability, and to prevent the rear axle from
entering ABS before the front axle.
Electronic Roll Mitigation (ERM)
The ERM 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 vehicle’s speed are sufficient to
potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine
WARNING!
The Brake Assist System (BAS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded
by prevailing road conditions. BAS cannot
prevent collisions, including 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.

ESC Operating Modes
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.
Partial Off
This mode may be useful if the vehicle becomes
stuck. This mode may modify TCS and ESC
thresholds for activation, which allows for more
wheel spin than normally allowed.
To enter the “Partial Off” mode, momentarily push
the ESC OFF button and the ESC OFF Indicator
Light will illuminate. To turn the ESC on again,
momentarily push the ESC OFF button and the ESC
OFF Indicator Light will turn off.
NOTE:For vehicles with multiple partial ESC modes, the
push and release of the button will toggle the ESC
modes. Multiple attempts may be required to
return to “ESC On”. 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 button 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 instrument cluster. To
turn ESC on again, momentarily push the ESC OFF
button.
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”.
If equipped with Off Road+ and if Off Road+ is
active when "Full Off" mode is enabled by the
driver, ESC will not switch to "Partial Off" mode at
any speed and will remain in "Full Off" mode until
Off Road+ is exited or ESC is re-enabled by the
driver.WARNING!
When in “Partial Off” mode, the TCS function
-
ality 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 enhanced 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.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled.
Therefore, enhanced vehicle stability offered
by the ESC system is unavailable. In an emer -
gency evasive maneuver, the ESC system will
not engage to assist in maintaining stability.
ESC “Full Off” mode is intended for off-highway
or off-road use only.
The 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 all accidents, including those
resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC
also cannot prevent collisions.

Selec-Speed Control (SSC) — If Equipped
SSC is intended for off-road driving in
4WD Low only. SSC maintains vehicle
speed by actively controlling engine
torque and brakes.
SSC has three states:
1. Off (feature is not enabled and will not activate)
2. Enabled (feature is enabled and ready but activation conditions are not met, or driver is
actively overriding with brake or throttle
application)
3. Active (feature is enabled and actively controlling vehicle speed)
Enabling SSC
SSC is enabled by pushing the SSC switch, but the
following conditions must also be met to enable
SSC:
The driveline is in 4WD Low.
The vehicle speed is below 5 mph (8 km/h).
The parking brake is released.
The driver seat belt is buckled.
The driver is not applying throttle.
The driver door is closed (If doors are attached,
the door must be closed. If doors are detached,
then driver seat belt must be buckled). Activating SSC
Once SSC is enabled it will activate automatically
once the following conditions are met:
The driver releases the throttle.
The driver releases the brake.
The transmission is in any selection other than
PARK.
Your vehicle speed is below 20 mph (32 km/h).
The driver door is closed (If doors are attached,
the door must be closed. If doors are detached,
then driver seat belt must be buckled).
The set speed for SSC is selectable by the driver,
and can be adjusted by using the gear shift +/-.
Additionally, the SSC set speed may be reduced
when climbing a grade and the level of set speed
reduction depends on the magnitude of grade. The
following summarizes the SSC set speeds:
SSC Target Set Speeds
1st = 0.6 mph (1 km/h)
2nd = 1.2 mph (2 km/h)
3rd = 1.8 mph (3 km/h)
4th = 2.5 mph (4 km/h)
5th = 3.1 mph (5 km/h)
6th = 3.7 mph (6 km/h)
7th = 4.3 mph (7 km/h)
8th = 5 mph (8 km/h)
9th = 5.6 mph (9 km/h) — if equipped
REVERSE = 0.6 mph (1 km/h)
NEUTRAL = 1.2 mph (2 km/h)
PARK = SSC remains enabled but not active
SSC Target Set Speeds — If Equipped With Off
Road+
1st = 0.6 mph (1 km/h)
2nd = 0.9 mph (1.5 km/h)
3rd = 1.2 mph (2 km/h)
4th = 1.5 mph (2.5 km/h)
5th = 1.8 mph (3 km/h)
6th = 2.5 mph (4 km/h)
7th = 3.7 mph (6 km/h)
8th = 5 mph (8 km/h)
REVERSE = 0.6 mph (1 km/h)
NEUTRAL = 1.2 mph (2 km/h)
PARK = SSC remains enabled but not active
NOTE:
During SSC, the +/- gear selector input is used
for SSC target speed selection but will not affect
the gear chosen by the transmission. While

actively controlling SSC, the transmission will
shift appropriately for the driver-selected set
speed and corresponding driving conditions.
SSC operation is influenced by Off Road+ drive
mode if active. The differences may be notable
to the driver as a varying level of aggressive -
ness.
Driver Override
The driver may override SSC activation with throttle
or brake application at any time.
Deactivating SSC
SSC will be deactivated but remain available if any
of the following conditions occur:
The driver overrides SSC set speed with throttle
or brake application.
The vehicle speed exceeds 20 mph (32 km/h)
but remains below 40 mph (64 km/h).
The vehicle is shifted into PARK.
Disabling SSC
SSC will deactivate and be disabled if any of the
following conditions occur:
The driver pushes the SSC switch.
The driveline is shifted out of the 4WD Low.
The parking brake is applied.
The vehicle is driven greater than 20 mph
(32 km/h) for greater than 70 seconds.
The vehicle is driven greater than 40 mph
(64 km/h). SSC will exist immediately.
The driver door opens (Driver door opens if
doors are attached or driver seat belt is
unbuckled if doors are detached).
Feedback To The Driver
The instrument cluster has an SSC icon and the
SSC switch has a lamp that offers feedback to the
driver about the state SSC is in.
The cluster icon and switch lamp will illuminate
and remain on solid when SSC is enabled or
activated. These are the normal operating
conditions for SSC.
The cluster icon and switch lamp will flash for
several seconds then extinguish when the driver
pushes the SSC switch but enabled conditions
are not met.
The cluster icon and switch lamp will flash for
several seconds then extinguish when SSC
disables due to excess speed.
The cluster icon and switch lamp will flash then
extinguish when SSC deactivates due to over -
heated brakes.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin for
each of the driven wheels. If wheel spin is
detected, the TCS may apply brake pressure to the
spinning wheel(s) and/or reduce engine power to
provide enhanced acceleration and stability. A
feature of the TCS, Brake Limited Differential (BLD)
functions similarly to a limited slip differential 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. BLD
may remain enabled even if TCS and ESC are in
reduced modes.
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.
WARNING!
SSC is only intended to assist the driver in
controlling vehicle speed when driving in
off-road conditions. The driver must remain
attentive to the driving conditions and is
responsible for maintaining a safe vehicle
speed.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nut/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check the area under vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
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 interfer -
ence, with the vehicle properly parked with the
engine off, fully press the accelerator, the
brake, and the clutch pedal (if present) to
check for interference. If your floor mat inter -
feres 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.
WARNING!
ALWAYS make sure objects cannot fall or slide
into the driver’s side floor area when the
vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners are
secure to the vehicle carpet. Fully press each
pedal to check for interference with the accel -
erator, brake, or clutch pedals then re-install
the floor mats.
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,
always check your floor mat has been properly
installed and is secured to your vehicle using
the floor mat fasteners by lightly pulling mat.
WARNING!

IN CASE OF EMERGENCY341
Rear Jacking Location
5. Raise the vehicle by turning the jack screw clockwise. Raise the vehicle only until the tire
just clears the ground surface and enough
clearance is obtained to install the spare tire.
Minimum tire lift provides maximum stability. 6. Remove the lug nuts and wheel.
7. Mount the spare tire on the axle.
8. Install the lug nuts with the cone-shaped end
toward the wheel. Lightly tighten the lug nuts
clockwise.
9. Lower the vehicle by turning the jack screw counterclockwise, and remove the jack. 10. Finish tightening the wheel bolts. Push down
on the wrench while at the end of the handle
for increased leverage. Tighten the wheel bolts
in a star pattern until each wheel bolt has been
tightened twice Úpage 418. If in doubt about
the correct tightness, have them checked with
a torque wrench by an authorized dealer or at
a service station.
11. After 25 miles (40 km), check the lug nut torque with a torque wrench to ensure that all
lug nuts are properly seated against the wheel.
12. Remove the jack assembly and wheel blocks.
13. Secure the jack and tools in their proper locations.
CAUTION!
Before raising the wheel off the ground, make
sure that the jack will not damage surrounding
truck parts and adjust the jack position as
required.
WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off the
jack and hurt someone near it. Raise the vehicle
only enough to remove the tire.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the wheel nuts fully until the
vehicle has been lowered. Failure to follow this
warning may result in serious injury.WARNING!
A loose tire or jack thrown forward in a collision
or hard stop, could endanger the occupants of
the vehicle. Always stow the jack parts and the
spare tire in the places provided.7

382SERVICING AND MAINTENANCE
(Continued)
Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating
conditions. Routine fluid level checks are not
required; therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service tools.
If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.
Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.Routine fluid and filter changes are not required.
However, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only manufacturer's specified
transmission fluid Ú
page 426. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid.
NOTE:No chemical flushes should be used in any trans -
mission; only the approved lubricant should be
used.
FUSES
General Information
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe transmis -
sion damage may occur. An authorized dealer
has the proper tools to adjust the fluid level
accurately.
CAUTION!
Using a transmission fluid other than
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder Ú page 426.
WARNING!
When replacing a blown fuse, always use an
appropriate replacement fuse with the same
amp rating as the original fuse. Never replace
a fuse with another fuse of higher amp rating.
The use of a fuse with a rating other than indi -
cated may result in a dangerous electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem in the
circuit that must be corrected. Never replace a
blown fuse with metal wires or any other mate -
rial. Failure to use proper fuses may result in
serious personal injury, fire and/or property
damage.
Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
If the replaced fuse blows again, contact an
authorized dealer.

VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the
A-pillar, visible from outside of the vehicle through
the windshield.
Vehicle Identification Number
NOTE:It is illegal to remove or alter the VIN plate.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems lose
normal capability, the remaining system will still
function. However, there will be some loss of
overall braking effectiveness. You may notice
increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Light.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off)
the brakes will still function. However, the effort
required to brake the vehicle will be much greater
than that required with the power system
operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to the
vehicle. Any time a wheel has been removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a six-sided (hex) deep wall
socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug nuts/
bolts and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
