system will release brake pressure and the vehicle will roll
down the hill as normal.
The following conditions must be met in order for HSA to
activate:
•The feature must be enabled.
• The vehicle must be stopped.
• Park brake must be off.
• Driver door must be closed.
• The vehicle must be on a sufficient grade.
• The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE gear).
• HSA will work in REVERSE gear and all forward gears.
The system will not activate if the transmission is in
PARK or NEUTRAL. For vehicles equipped with a
manual transmission, if the clutch is pressed, HSA will
remain active.WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur,
such as on minor hills or with a loaded vehicle, or
while pulling a trailer. HSA is not a substitute for
active driving involvement. It is always the driver ’s
responsibility to be attentive to distance to other ve-
hicles, people, and objects, and most importantly brake
operation to ensure safe operation of the vehicle under
all road conditions. Your complete attention is always
required while driving to maintain safe control of your
vehicle. Failure to follow these warnings can result in
a collision or serious personal injury.
Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
• If disabling HSA using your instrument cluster display,
refer to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
• If disabling HSA using Uconnect Settings, refer to
“Uconnect Settings” in “Multimedia” for further infor-
mation.

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 accelera-
tor, 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.

WARNING! (Continued)
•ALWAYS REMOVE THE EXISTING FLOOR MAT
FROM THE VEHICLE
before installing any
other floor mat. NEVER install or stack an addi-
tional 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,

SAFETY 281

WARNING!(Continued)
•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 accelera-
tor, 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 depress each pedal to check for
interference with the accelerator, 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

secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make 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 wheel nuts for tightness. Check the tires (includ-
ing 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 area under vehicle after overnight parking for fuel,
engine 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.
282 SAFETY

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
•When leaving the vehicle, always remove the key fob
from the ignition and lock your vehicle.
• 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 gear selector.
• Do not leave the key fob in or near the vehicle, or in
a location accessible to children. A child could oper-
ate power windows, other controls, or move the
vehicle.
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
Manual Transmission — If Equipped
Apply the parking brake, place the gear selector in NEU-
TRAL, and press the clutch pedal before starting the
vehicle. This vehicle is equipped with a clutch interlocking
ignition system. It will not start unless the clutch pedal is
pressed to the floor.
Four-Wheel Drive Models Only
In 4L mode, this vehicle will start regardless of whether or
not the clutch pedal is pressed to the floor. This feature
enhances off-road performance by allowing the vehicle to
start when in 4L without having to press the clutch pedal.
The “4WD Indicator Light” will illuminate when the
transfer case has been shifted into this mode.
Automatic Transmission — If Equipped
Start the vehicle with the gear selector in the PARK
position (vehicle can also be started in NEUTRAL). Apply
the brake before shifting to any driving range.
Normal Starting — Gasoline Engine
NOTE: Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.

STARTING AND OPERATING 285

WARNING!(Continued)
touch the parking brake, brake pedal or the gear
selector.
• Do not leave the key fob in or near the vehicle, or in
a location accessible to children. A child could oper-
ate power windows, other controls, or move the
vehicle.
• Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.
• Always fully apply the parking brake when leaving
your vehicle or it may roll and cause damage or
injury. Also, be certain to leave an automatic trans-
mission in PARK, a manual transmission in RE-
VERSE or first gear. Failure to do so may cause the
vehicle to roll and cause damage or injury.
CAUTION!
If the “Brake Warning Light” remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.
MANUAL TRANSMISSION — IF EQUIPPED
WARNING!
You or others could be injured if you leave the vehicle
unattended without having the parking brake fully
applied. The parking brake should always be applied
when the driver is not in the vehicle, especially on an
incline.
CAUTION!
Never drive with your foot resting on the clutch pedal,
or attempt to hold the vehicle on a hill with the clutch
pedal partially engaged, as this will cause abnormal
wear on the clutch.
290 STARTING AND OPERATING

NOTE:During cold weather, you may experience in-
creased effort in shifting until the transmission fluid warms
up. This is normal.Shifting
Fully press the clutch pedal before shifting gears. As you
release the clutch pedal, lightly press the accelerator pedal.
You should always use first gear when starting from a
standing position.
Recommended Vehicle Shift Speeds
To utilize your manual transmission efficiently for both
fuel economy and performance, it should be upshifted as
listed in recommended shift speed chart. Shift at the
vehicle speeds listed for acceleration. When heavily loaded
or pulling a trailer these recommended up-shift speeds
may not apply.
Manual Transmission Shift Speeds in MPH (KM/H)
Engine Speeds 1 to 2 2 to 33 to 44 to 5 5 to 6
3.6L Accel. 15 (24) 24 (39) 34 (55) 47 (76) 56 (90)
Cruise 10 (16) 19 (31) 27 (43) 37 (60) 41 (66)
NOTE: Vehicle speeds shown in the chart above are for 2H
and 4H only, vehicle speeds in 4L would be significantly
less.
Shift Pattern

STARTING AND OPERATING 291

Downshifting
Moving from a high gear down to a lower gear is recom-
mended to preserve brakes when driving down steep hills.
In addition, downshifting at the right time provides better
acceleration when you desire to resume speed. Downshift
progressively. Do not skip gears to avoid overspeeding the
engine and clutch.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip, and the vehicle could skid.
CAUTION!
•Skipping gears and downshifting into lower gears at
higher vehicle speeds can damage the engine and
clutch systems, Any attempt to shift into lower gear
with clutch pedal depressed may result damage to
the clutch system. Shifting into lower gear and
releasing the clutch may result in engine damage.
(Continued)
CAUTION! (Continued)
•When descending a hill, be very careful to downshift
one gear at a time to prevent overspeeding the engine
which can cause engine damage, and/or clutch dam-
age, even if the clutch pedal is pressed. If transfer
case is in low range the vehicle speeds to cause
engine and clutch damage are significantly lower.
• Failure to follow the maximum recommended down-
shifting speeds may cause the engine damage and/or
damage the clutch, even if the clutch pedal is
pressed.
• Descending a hill in low range with clutch pedal
depressed could result in clutch damage.
Maximum Recommended Downshift Speeds
CAUTION!
Failure to follow the maximum recommended down-
shifting speeds may cause the engine to overspeed
and/or damage the clutch disc, even if the clutch pedal
is pressed.
292 STARTING AND OPERATING

Manual Transmission Downshift Speeds in MPH (KM/H)
Gear Selection 6 to 5 5 to 44 to 33 to 2 2 to 1
Maximum Speed 80 (129) 70 (113)50 (81)30 (48) 15 (24)
NOTE: Vehicle speeds shown in the chart above are for 2H
and 4H only, vehicle speeds in 4L would be significantly
less.
Reverse Shifting
To shift into REVERSE, bring the vehicle to a complete
stop. Press the clutch and pause briefly to allow the gear
train to stop rotating. Beginning from the NEUTRAL
position, move the gear selector in one quick, smooth
motion straight across and into the REVERSE area (the
driver will feel a firm “click” as the shifter passes the
“knock-over”). Complete the shift by pulling the gear
selector into REVERSE.
The “knock-over” provides a resistance to the driver from
accidentally entering the REVERSE shift area and warns
the driver that they are about to shift the transmission into
REVERSE. Due to this feature, a slow shift to REVERSE can
be perceived as a high shift effort.
AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!
Damage to the transmission may occur if the following
precautions are not observed:
• Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
• Do not shift between PARK, REVERSE, NEUTRAL,
or DRIVE when the engine is above idle speed.
• Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
6
STARTING AND OPERATING 293

CAUTION!
Exceeding 25 mph (40 km/h) while the transfer case is
engaged in 4L may result in an engine overspeed
condition and engine damage.
The “4WD Indicator Light” (located in the instrument
cluster) will illuminate when the transfer case is shifted
into the 4L position.
NOTE: When in 4L, the “ESC Off Indicator Light” will
display in the instrument cluster.
Shifting Procedure
2H to 4H or 4H to 2H
Shifting between 2H and 4H can be made with the vehicle
stopped or in motion. With the vehicle in motion, the
transfer case will engage/disengage faster if you momen-
tarily release the accelerator pedal after completing the
shift. Apply a constant force when shifting the transfer case
lever.
4H to 4L or 4L to 4H
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift an
automatic transmission into NEUTRAL (N), or press the
clutch pedal on a manual transmission. While the vehicle is coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer case
lever firmly to the desired position. Do not pause with the
transfer case in N (Neutral). Once the shift is completed,
place the automatic transmission into DRIVE or release the
clutch pedal on a manual transmission.
NOTE:
Shifting into or out of 4L is possible with the
vehicle completely stopped; however, difficulty may occur
due to the mating teeth not being properly aligned. Several
attempts may be required for clutch teeth alignment and
shift completion to occur. The preferred method is with the
vehicle rolling at 2 to 3 mph (3 to 5 km/h). Avoid
attempting to engage or disengage 4L with the vehicle
moving faster than 2 to 3 mph (3 to 5 km/h).
WARNING!
Failure to engage a transfer case position completely
can cause transfer case damage or loss of power and
vehicle control. You could have a collision. Do not
drive the vehicle unless the transfer case is fully
engaged.
304 STARTING AND OPERATING

The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector. Refer
to the following illustration.
Towing Tips
Before setting out on a trip, practice turning, stopping and
backing the trailer in an area away from heavy traffic.If using a manual transmission vehicle for trailer towing,
all starts must be in first gear to avoid excessive clutch
slippage.
Automatic Transmission — If Equipped
Select the DRIVE range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. However, if frequent shifting does occur
while in DRIVE, you can use the AutoStick shift control to
manually select a lower gear.
NOTE:
Using a lower gear while operating the vehicle
under heavy loading conditions will improve performance
and extend transmission life by reducing excessive shifting
and heat buildup. This action will also provide better
engine braking.
If you REGULARLY tow a trailer for more than 45 minutes
of continuous operation, then change the transmission
fluid and filter as specified for police, taxi, fleet, or frequent
trailer towing. Refer to the “Maintenance Plan” for the
proper maintenance intervals.
NOTE: Check the automatic transmission fluid level before
towing.
