2017 JEEP WRANGLER four wheel drive

INTRODUCTION
Congratulations on selecting your new FCA US LLC ve-
hicle. Be assured that it represents precision workmanship,
distinctive styling, and high quality.
This is a specialized utility vehicle. It can go places and
perform tasks that are not intended for conventional pas-
senger cars. 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 version of this 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, transmission,
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 a collision.
Refer to “Driving Tips” in “Starting And Operating” for
further information.
This Owner’s Manual has been prepared with the assis-
tance of service and engineering specialists to acquaint you
with the operation and maintenance of your vehicle. It is
supplemented by Warranty Information, and various
customer-oriented documents. Please take the time to read
these publications carefully. Following the instructions and
recommendations in this manual will help assure safe and
enjoyable operation of your vehicle.

GETTING TO KNOW YOUR INSTRUMENT PANEL 207

Electronic Brake Force Distribution (EBD)
This 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.
Brake System Warning Light
The red “Brake System Warning Light” will turn on when
the ignition is turned to 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 re-
quired. If the “Brake System Warning Light” does not come
on when the ignition is turned to 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 sys-
tem 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-lockbrake system (ABS). Applying the brakes very quickly
results in the best BAS assistance. 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.
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 capa-
bilities 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.
Hill Start Assist (HSA)
The HSA system is designed to mitigate roll back from a
complete stop while on an incline. If the driver releases the
brake while stopped on an incline, HSA will continue to
hold the brake pressure for a short period. If the driver
216 SAFETY

For vehicles not equipped with an instrument cluster
display, perform the following steps:
1. Center the steering wheel (front wheels pointingstraight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn to the left.
6. Push the “ESC Off” button located in the lower switch bank below the climate control four times within 20
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an additional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was completed properly, the “ESC Off
Indicator Light” will blink several times to confirm HSA
is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.Traction Control System (TCS)
This system monitors the amount of wheel spin of 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 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. BLD may remain enabled even if TCS
and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counteract-
ing the over/under steer condition. Engine power may also
be reduced to help the vehicle maintain the desired path.
ESC 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
218 SAFETY

The ESC system has three available operating modes in 4H
range. The system has one operating mode in 4L range.
Two-wheel drive vehicles and four-wheel drive vehicles in
2H range have two operating modes.
4H Range (4WD Models)
ESC On
This is the normal operating mode for ESC in 4H range.
ESC Partial Off
This mode is entered by momentarily pushing the ESC
OFF switch. When inESC Partial Offmode, the TCS
portion 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.
This mode is intended to be used if the vehicle is in deep
snow, sand, or gravel conditions and more wheel spin than
ESC would normally allow is required to gain traction. To
turn ESC on again, momentarily push the ESC OFF switch.
This will restore the normal “ESC On” mode of operation. NOTE:
To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand, or
gravel, it may be desirable to switch to the ESC Partial Off
mode by pushing the ESC OFF switch. Once the situation
requiring ESC to be switched to the ESC Partial Offmode
is overcome, turn ESC back on by momentarily pushing the
ESC OFF switch. This may be done while the vehicle is in
motion.
WARNING!
• When in ESC 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 ESC Partial Off mode, the engine power
reduction feature of TCS is disabled, and the en-
hanced vehicle stability offered by the ESC system is
reduced.
• Trailer Sway control (TSC) is disabled when the ESC
system is in the ESC Partial Off mode.

However, the driver can override HDC operation by
applying the brake to slow the vehicle down below the
HDC control speed. If more speed is desired during HDC
control, the accelerator pedal will increase vehicle speed in
the usual manner. When either the brake or the accelerator
is released, HDC will control the vehicle at the original set
speed.
Enabling HDC
1. Shift the transfer case into 4WD LOW range. Refer to “Four-Wheel Drive Operation” in “Starting and Oper-
ating” for further information.
2. Push the “Hill Descent” button. The “Hill Descent Control Indicator Light” in the instrument cluster will
turn on solid. NOTE:
•If the transfer case is not in 4WD LOW range, the “Hill
Descent Control Indicator Light” will flash for five
seconds and HDC will not be enabled.
• If the ESC senses that the brakes are overheating the
“Hill Descent Control Indicator Light” will flash for
five seconds and HDC will become deactivated until
the brakes have cooled.
Disabling HDC
Push the “Hill Descent” button or shift the transfer case out
of 4WD LOW range. The “Hill Descent Control Indicator”
light in the instrument cluster will turn off.

Base System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim-mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.
NOTE:It is particularly important for you to check the tire
pressure in all of your tires regularly and to maintain the
proper pressure.
The Tire Pressure Monitor System (TPMS) consists of the
following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in the spare
wheel if the vehicle is equipped with a matching full size
spare wheel and tire assembly. The matching full size spare
tire can be used in place of any of the four road tires. A low
spare tire will not cause the “Tire Pressure Monitoring
Telltale Light” to illuminate or the chime to sound while
stowed in the spare location. The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, a “LOW TIRE
PRESSURE” message will display in the instrument
cluster, and an audible chime will be activated when one or
more of the four active road tire pressures are low. Should
this occur, you should stop as soon as possible, check the
inflation pressure of each tire on your vehicle, and inflate
each tire to the vehicle’s recommended cold placard pres-
sure value. The system will automatically update and the
“Tire Pressure Monitoring Telltale Light” will extinguish
once the updated tire pressures have been received. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.
The “Tire Pressure Monitoring Telltale Light” will flash on
and off for 75 seconds, and will remain on solid when a
system fault is detected. The system fault will also sound a
chime. If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. The “Tire
Pressure Monitoring Telltale Light” will turn off when the
fault condition no longer exists. A system fault can occur by
any of the following scenarios:
1. Jamming due to electronic devices or driving next to facilities emitting the same Radio Frequencies as the
TPM sensors.

will flash on and off for 75 seconds and then remain on
solid. For each subsequent ignition key cycle, a chime
will sound and the “Tire Pressure Monitoring Telltale
Light” will flash on and off for 75 seconds and then
remain on solid. Once you repair or replace the original
road tire, and reinstall it on the vehicle in place of the
spare tire, the TPMS will update automatically and the
“Tire Pressure Monitoring Telltale Light” will turn OFF,
as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. The
vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to
receive this information.
