WARNING!
Tilting the steering column while the vehicle is
moving is dangerous. Without a stable steering col-
umn, you could lose control of the vehicle and have
an accident. Adjust the column only while the ve-
hicle is stopped. Be sure it is locked before driving.
ELECTRONIC SPEED CONTROL — IF EQUIPPED
When engaged, this device takes over the accelerator
operation at speeds greater than 35 mph (56 km/h). The
speed control lever is located on the right side of the
steering wheel.
To Activate
Push the ON/OFF button. The Cruise Indicator Light in
the instrument cluster will illuminate. To turn the system
OFF, push the ON/OFF button a second time. The Cruise
Indicator Light will turn off. The system should be
turned OFF when not in use.

To Accelerate For Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Speed Control On Hills
NOTE:The speed control system maintains speed up
and down hills. A slight speed change on moderate hills
is normal.
On steep hills, a greater speed loss or gain and/or more
frequent downshifts (auto transmission only) may occur
so it may be preferable to drive without speed control.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes ABS (Anti-Lock Brake
System), TCS (Traction Control System), BAS (Brake
Assist System), ERM (Electronic Roll Mitigation), and ESP (Electronic Stability Program). All five of these
systems work together to enhance vehicle stability and
control in various driving conditions.
ABS (Anti-Lock Brake System)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up and
help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in Section 5 of this
manual for more information about ABS.

WARNING!
ABS (Anti-Lock Brake System) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ABS cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ABS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize the
user’s safety or the safety of others.
TCS (Traction Control System)
This system 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) to provide
enhanced acceleration and stability. A feature of the TCS
system functions similar 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. This feature remains active even if
TCS and ESP are in either the “Partial Off” or “Full Off”
modes. Refer to “ESP (Electronic Stability Program)” in
this section.

BAS (Brake Assist System)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing 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). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous brak-
ing pressure during the stopping sequence. Do not
reduce brake pedal pressure unless braking is no longer
desired. Once the brake pedal is released, the BAS is
deactivated.WARNING!
BAS (Brake Assist System) cannot prevent the natu-
ral laws of physics from acting on the vehicle, nor can
it increase the traction afforded by prevailing road
conditions. BAS cannot prevent accidents, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. Only a
safe, attentive, and skillful driver can prevent acci-
dents. 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.

maneuver must be performed to permanently disable
ESP and defeat the functionality of the ESP switch.
Repeating the procedure will return the system to normal
ESP operation and restore ESP switch functionality al-
lowing ESP “Partial” or “Off” modes.
WARNING!
With ESP in the permanent disable mode, enhanced
vehicle stability offered by the ESP and ERM sys-
tems is unavailable. In an emergency evasive maneu-
ver, the ESP and ERM systems will not engage to
assist in maintaining stability. This disabled mode is
intended for off-highway or off-road use only. Ve-
hicle modifications requiring the owner to configure
the vehicle in the ESP disabled mode, will seriously
affect the vehicles roadworthiness and safety and
may lead to loss of control and/or accident resulting
in possible serious or fatal injuries.The following procedure will disable (or re-enable) ESP
functionality in the vehicle.
1. Shift the transfer case into the 4H range position.
2. Turn the steering wheel until it is centered and the
wheels are pointed straight ahead.
3. Cycle the ignition key OFF to ON.
4. Wait approximately five seconds for the system bulb
check.
5. Turn and hold the steering wheel one-half turn to the
right (clockwise).
6. Press and hold the ESP OFF button for seven seconds.
7. Turn the steering wheel back to center, and turn and
hold an additional one-half turn to the left (counterclock-
wise).
8. Press and hold the ESP OFF button for seven seconds.

Front Panel(s) Installation
NOTE:The front panel(s) must be positioned properly
to ensure sealing. Set the panels on the windshield frame
so that there is no overhang. Also, make sure that the
panels are sitting flush with the body.
1. Install right panel first, then the left panel.
2. Reinstall panel(s) using the same steps for removal in
reverse order.
Front Panel(s) Installation Only (With Rear Hard
Top Removed)
1. Turn left and right panels over and move spacer block
(located on rear of panel) upward 90 degrees. NOTE:
The front panel(s) must be positioned properly
to ensure sealing. Set the panels on the windshield frame
so that there is no overhang. Also, make sure that the
panels are sitting flush with the body.
2. Install right panel first, then the left panel.

6. Locate the wiring harness on the left rear inside corner
of the vehicle.
7. Disconnect the rear window washer hose and install
the tethered cap.CAUTION!
Make sure storage cap is installed to prevent foreign
materials from entering washer tube and clogging
system, and also to prevent fluid from being sprayed
into the rear of the vehicle.
8. Disconnect the wire harness from the hard top by
pressing the tab at the side of the connector and pulling
to disconnect.
NOTE: If the red latch on the connector is locked, push
the red latch to the right until you can only see the latch
on one end (right) of the connector. This will unlock the
connector tab, allowing the tab to be pressed down and
enabling the harness to be disconnected from the hard
top.
