steering JEEP WRANGLER 2010 Owners Manual

INTRODUCTION
Congratulations on selecting your new Chrysler Group
LLC vehicle. Be assured that it represents precision
workmanship, distinctive styling, and high quality - all
essentials that are traditional to our vehicles.
This is a specialized utility vehicle designed for both
on-road and off-road use. It can go places and perform
tasks for which conventional two-wheel drive enclosed
vehicles were not intended. It handles and maneuvers
differently from many passenger cars both on-road and
off-road, so take time to become familiar with your
vehicle.
The two-wheel drive utility vehicle was designed for
on-road use only. It is not intended for off-road driving
or use in other severe conditions suited for a four-wheel
drive vehicle.Before you start to drive this vehicle, read the Owner’s
Manual. Be sure you are familiar with all vehicle controls,
particularly those used for braking, steering, transmis-
sion, and transfer case shifting. Learn how your vehicle
handles on different road surfaces. Your driving skills
will improve with experience. When driving off-road or
working the vehicle, don’t overload the vehicle or expect
the vehicle to overcome the natural laws of physics.
Always observe federal, state, provincial and local laws
wherever you drive.
As with other vehicles of this type, failure to operate this
vehicle correctly may result in loss of control or an
accident. Refer to “On-Road/Off-Road Driving Tips” in
“Starting And Operating” for further information.

Supplemental Restraint System (SRS) — Airbags
This vehicle has Advanced Front Airbags for both the
driver and right front passenger as a supplement to the
seat belt restraint systems. The driver’s Advanced Front
Airbag is mounted in the steering wheel. The front
passenger airbag is mounted in the instrument panel,
above the glove compartment. The letters SRS are em-
bossed on the airbag covers.NOTE:These airbags are certified to the new Federal
regulations for Advanced Airbags.

NOTE:The driver side upper windshield trim contains
the microphone for the Uconnect™ Phone.
Voice Command Button Actual button location may vary with the ra-
dio. The individual buttons are described in the
“Operation” section.
The Uconnect™ Phone can be used with any Hands-Free
Profile certified Bluetooth cellular phone. See the
Uconnect™ website for supported phones. Refer to your
cellular service provider or the phone manufacturer for
details.
The Uconnect™ Phone is fully integrated with the vehi-
cle’s audio system. The volume of the Uconnect™ Phone
can be adjusted either from the radio volume control
knob or from the steering wheel radio control (right
switch), if so equipped. The radio display will be used for visual prompts from
the Uconnect™ Phone such as
CELLor caller ID on
certain radios.
Operation
Voice commands can be used to operate the Uconnect™
Phone and to navigate through the Uconnect™ Phone
menu structure. Voice commands are required after most
Uconnect™ Phone prompts. You will be prompted for a
specific command and then guided through the available
options.
•Prior to giving a voice command, one must wait for
the beep, which follows the Readyprompt or another
prompt.
•For certain operations, compound commands can be
used. For example, instead of saying Setupand then
Phone Pairing, the following compound command
can be said: Setup Phone Pairing.

WARNING!
Do not adjust the steering column while driving.
Adjusting the steering column while driving or driv-
ing with the steering column unlocked, could cause
the driver to lose control of the vehicle. Be sure the
steering column is locked before driving your ve-
hicle. Failure to follow this warning may result in
serious injury or death.
ELECTRONIC SPEED CONTROL — IF EQUIPPED
Electronic Speed Control takes over the accelerator op-
eration at speeds greater than 25 mph (40 km/h). The
Electronic Speed Control lever is located on the right side
of the steering wheel.NOTE:
In order to ensure proper operation, the Elec-
tronic Speed Control System has been designed to shut
down if multiple Speed Control functions are operated at
the same time. If this occurs, the Electronic Speed Control

REAR WINDOW FEATURES — HARD TOP ONLY
Rear Window Wiper/Washer — If Equipped
A rotary switch on the center portion of the control lever
(located on the right side of the steering column) controls
the operation of the rear wiper/washer function.Rotate the switch upward to the first detent posi-
tion for rear wiper operation.
Rotate the switch upward past the first detent to
activate the rear washer. The washer pump will
continue to operate as long as the switch is held.
Upon release, the wiper will cycle two to three times
before returning to the set position.
If the rear wiper is operating when the ignition is turned
to the LOCK position, the wiper will automatically return
to the “Park” position. When the vehicle is restarted, the
wiper will resume function at whichever position the
switch is set at.

The Basics of Off-Road Driving
You will encounter many types of terrain driving off-
road. You should be familiar with the terrain and area
before proceeding. There are many types of surface
conditions: hard-packed dirt, gravel, rocks, grass, sand,
mud, snow and ice. Every surface has a different effect on
your vehicle’s steering, handling and traction. Control-
ling your vehicle is one of the keys to successful off-road
driving, so always keep a firm grip on the steering wheel
and maintain a good driving posture. Avoid sudden
accelerations, turns or braking. In most cases, there are no
road signs, posted speed limits or signal lights. Therefore,
you will need to use your own good judgment on what is
safe and what is not. When on a trail, you should always
be looking ahead for surface obstacles and changes in
terrain. The key is to plan your future driving route while
remembering what you are currently driving over.

system. This noise should be considered normal, and it
does not in any way damage the steering system.

WARNING! (Continued)
•HSA is not a parking brake. If you stop the vehicle
on a hill without putting the transmission in
PARK and using the parking brake, it will roll
down the hill and could cause a collision with
another vehicle or object. Always remember to use
the parking brake while parking on a hill, and that
the driver is responsible for braking the vehicle.
HSA Off
If you wish to turn off the HSA system, follow this
procedure:
1. Start with the engine off and vehicle in PARK (auto-
matic transmission) or NEUTRAL with clutch out
(manual transmission) with wheels straight. Apply park-
ing brake on manual transmission vehicle.
2. Start the engine.3. With the engine running, the brake applied, and the
clutch out, rotate the steering wheel 180° counterclock-
wise from center.
4. Press the ESP OFF switch four times within twenty
seconds.
5. Rotate the steering wheel 360° clockwise (180° clock-
wise from center).
6. Cycle ignition switch OFF then ON.
7. If the sequence was completed properly, the “ESP/
TCS Indicator Light” will blink several times to confirm
HSA is off.
Steps 1-7 must be completed within 90 seconds to turn off
HSA. Repeat steps 1-7 to re-enable HSA functionality.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the

counteracting the over/under steer condition. Engine
power may also be reduced to help the vehicle maintain
the desired path.
ESP uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESP applies the brake of the appropri-
ate wheel to assist in counteracting the oversteer or
understeer condition.
•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.
The “ESP/TCS Indicator Light” (located in the instru-
ment cluster), starts to flash as soon as the tires lose
traction and the ESP system becomes active. The “ESP/
TCS Indicator Light” also flashes when TCS is active. If the “ESP/TCS 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 conditions.
