Jeep Cherokee (2019 year). Manual — part 18

SPORT — If Equipped

This mode alters the transmission’s automatic shift sched-
ule for sportier driving. Upshift speeds are increased to
make full use of available engine power.

SPORT mode is activated using the rotary switch on the
center console. Refer to

⬙Selec-Terrain⬙ in this section for

further information.

Transmission Limp Home Mode

Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in a fixed gear, or may remain in NEUTRAL.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home Mode may allow the vehicle to be driven to an
authorized dealer for service without damaging the trans-
mission.

In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK.

3. Turn the ignition to the OFF position.

4. Wait approximately 10 seconds.

5. Restart the engine.

6. Shift into the desired gear range. If the problem is no

longer detected, the transmission will return to normal
operation.

NOTE:

Even if the transmission can be reset, we recom-

mend that you visit an authorized dealer at your earliest
possible convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission. If
the transmission cannot be reset, authorized dealer service
is required.

AutoStick

AutoStick is a driver-interactive transmission feature pro-
viding manual shift control, giving you more control of the
vehicle. AutoStick allows you to maximize engine braking,
eliminate undesirable upshifts and downshifts, and im-
prove overall vehicle performance. This system can also
provide you with more control during passing, city driv-
ing, cold slippery conditions, mountain driving, trailer
towing and many other situations.

276

STARTING AND OPERATING

Operation

When the gear selector is in the AutoStick position (beside
the DRIVE position), it can be moved forward and rear-
ward. This allows the driver to manually select the trans-
mission gear being used. Moving the gear selector forward
(-) triggers a downshift, and rearward (+) an upshift. The
current gear is displayed in the instrument cluster.

NOTE:

In AutoStick mode, the transmission will only shift

up or down when the driver moves the gear selector
rearward (+) or forward (-), except as described below.
• The transmission will automatically upshift when nec-

essary to prevent engine overspeed.

• The transmission will automatically downshift as the

vehicle slows (to prevent engine lugging) and will
display the current gear.

• The transmission will automatically downshift to first or

second gear (depending on model) when coming to a
stop. After a stop, the driver should manually upshift (+)
the transmission as the vehicle is accelerated.

• You can start out (from a stop) in first or second gear.

Starting out in second gear can be helpful in snow or icy

conditions. Tap the gear selector forward or rearward to
select the desired gear after the vehicle is brought to a
stop.

• If a requested downshift would cause the engine to

overspeed, that shift will not occur.

• The system will ignore attempts to upshift at too low of

a vehicle speed.

• Avoid using speed control when AutoStick is engaged

because the transmission will not shift automatically.

• Transmission shifting will be more noticeable when

AutoStick is enabled.

• The system may revert to automatic shift mode if a fault

or overheat condition is detected.

To disengage AutoStick mode, return the gear selector to
the DRIVE position. You can shift in or out of the AutoStick
position at any time without taking your foot off the
accelerator pedal.

STARTING AND OPERATING

277

WARNING!

Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.

Torque Converter Clutch

A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly different
feeling or response during normal operation in the upper
gears. When the vehicle speed drops or during some
accelerations, the clutch automatically disengages.

NOTE:

The torque converter clutch will not engage until

the transmission fluid is warm (usually after 1 to 3 miles [2
to 5 km] of driving). Because the engine speed is higher
when the torque converter clutch is not engaged, it may
seem as if the transmission is not shifting properly when
cold. This is normal. The torque converter clutch will
function normally once the transmission is sufficiently
warm.

FOUR-WHEEL DRIVE OPERATION

1-Speed Four-Wheel Drive (4X4) — If Equipped

This feature provides on-demand four-wheel drive (4X4).
The system is automatic with no driver inputs or addi-
tional driving skills required. Under normal driving con-
ditions, the front wheels provide most of the traction. If the
front wheels begin to lose traction, power is shifted auto-
matically to the rear wheels. The greater the front wheel
traction loss, the greater the power transfer to the rear
wheels.

1-Speed 4X4 Switch

278

STARTING AND OPERATING

Additionally, on dry pavement under heavy throttle input
(where one may have no wheel spin), torque will be sent to
the rear in a pre-emptive effort to improve vehicle launch
and performance characteristics.

CAUTION!

All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire size
may cause failure of the power transfer unit.

2-Speed Four-Wheel Drive (4x4) — If Equipped

The Four-Wheel Drive is fully automatic in the normal
driving mode. The Selec-Terrain buttons provide three
selectable mode positions:
• 4WD LOW
• REAR LOCK (If Equipped)
• NEUTRAL
When additional traction is required, the 4WD LOW range
position can be used to provide an additional gear reduc-
tion which allows for increased torque to be delivered to
both the front and rear wheels. 4WD LOW is intended for

2-Speed 4x4 Switch

2-Speed 4x4 Switch (with Rear Lock)

STARTING AND OPERATING

279

loose, slippery road surfaces only. Driving in 4WD LOW on
dry, hard-surfaced roads may cause increased tire wear and
damage to driveline components.

When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the normal
driving mode at a given road speed. Take care not to
overspeed the engine and do not exceed 50 mph (80 km/h).

Proper operation of four-wheel drive vehicles depends on
tires of equal size, type, and circumference on each wheel.
Any difference will adversely affect shifting and cause
damage to the driveline components.

Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.

Shift Positions

For additional information on the appropriate use of each
4WD system mode position, see the information below:

NEUTRAL

This range disengages the driveline from the powertrain. It
is to be used for flat towing behind another vehicle.

Refer to “Recreational Towing” in “Starting And Operat-
ing” for further information.

WARNING!

You or others could be injured or killed if you leave the
vehicle unattended with the power transfer unit in the
NEUTRAL (N) position without first fully engaging
the parking brake. The NEUTRAL (N) position disen-
gages both the front and rear driveshafts from the
powertrain and will allow the vehicle to roll, even if
the transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.

4WD LOW

This range is for low speed four-wheel drive. It provides an
additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose, slip-
pery road surfaces only. Do not exceed 25 mph (40 km/h).

NOTE:

Refer to “Selec-Terrain — If Equipped” for further

information on the various positions and their intended
usages.

280

STARTING AND OPERATING

Shifting Procedures

Shifting Into 4X4 LOW

With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition in the ON mode and the engine running, shift the
transmission into NEUTRAL, and push the “4WD LOW”
button once. The “4WD LOW” indicator light in the
instrument cluster will begin to flash and remain on solid
when the shift is complete.

NOTE:

If shift conditions/interlocks are not met, a mes-

sage will flash from the instrument cluster display with
instructions on how to complete the requested shift.

Refer to “Instrument Cluster Display” in “Getting To know
Your Instrument Panel” for further information.

Shifting Out Of 4X4 LOW

NOTE:
• If shift conditions/interlocks are not met, a message will

flash from the instrument cluster display with instruc-
tions on how to complete the requested shift. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.

• Shifting into or out of 4WD LOW is possible with the

vehicle completely stopped; however, difficulty may
occur due to the mating clutch 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 0 to 3 mph
(0 to 5 km/h). If the vehicle is moving faster than 3 mph
(5 km/h), the 4WD system will not allow the shift.

begin to flash. When the shift is complete the REAR
LOCK indicator lights will remain on.

• When disengaging Rear E-Locker, the indicator lights in

the instrument cluster and on the REAR LOCK button
will begin to flash. When the shift is complete the REAR
LOCK indicator lights will remain off.

• Shifting into or out of Rear E-Locker is possible with the

vehicle completely stopped; however, difficulty may
occur due to the mating clutch teeth not being properly
aligned. Several attempts may be required for clutch
teeth alignment and shift completion to occur. The
preferred method is for the vehicle to be rolling, below
15 MPH (24 km/h), while including right and left
steering maneuvers to allow for the clutch teeth to align.

• The Rear E-Locker System must be disengaged prior to

taking the vehicle out of 4WD LOW range. If 4WD LOW
shift conditions/interlocks are not met, a message will
flash from the instrument cluster display with instruc-
tions on how to complete the requested shift.

SELEC-TERRAIN

Description

Selec-Terrain combines the capabilities of the vehicle con-
trol systems, along with driver input, to provide the best
performance for all terrains.

Rotate the Selec-Terrain knob to select the desired mode.

284

STARTING AND OPERATING

Selec-Terrain offers the following modes:
• Auto — Fully automatic full time four-wheel drive

operation can be used on and off road. Balances traction
with seamless steering feel to provide improved han-
dling and acceleration over two-wheel drive vehicles.

• Snow — Tuning set for additional stability in inclement

weather. Use on and off road on loose traction surfaces
such as snow. When in SNOW mode (depending on
certain operating conditions), the transmission may use
second gear (rather than first gear) during launches, to
minimize wheel slippage.

• Sport — This mode alters the transmission’s automatic

shift schedule for sportier driving. Upshift speeds are
increased to make full use of available engine power.

NOTE:

SPORT mode is not available when 4WD LOW is

selected.
• Sand/Mud — Off-road calibration for use on low trac-

tion surfaces such as mud, sand, or wet grass. Driveline
is maximized for traction. Some binding may be felt on
less forgiving surfaces. The electronic brake controls are
set to limit traction control management of throttle and
wheel spin.

• Rock — Off-road calibration only available in 4WD

LOW range. Traction based tuning with improved steer-
ability for use on high traction off-road surfaces. Use for
low speed obstacles such as large rocks, deep ruts, etc.

NOTE:
• Rock mode is only available on the vehicles equipped

with the Off-Road package.

• Activate the Hill Descent Control or Selec Speed Control

for steep downhill control.

Instrument Cluster Display Messages

When the appropriate conditions exist, a message will
appear in the instrument cluster. Refer to “Instrument
Cluster Display” in “Getting To Know Your Instrument
Panel” for further information.

POWER STEERING

The electric power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the
electric steering system experiences a fault that reduces
assist or prevents the vehicle from providing assist, you
will still have the ability to steer the vehicle manually.

WARNING!

Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.

If the “SERVICE POWER STEERING

⬙ OR

⬙POWER STEERING ASSIST OFF - SERVICE
SYSTEM” message and a steering wheel icon are
displayed on the instrument cluster display

screen, it indicates that the vehicle needs to be taken to the
dealer for service. It is likely the vehicle has lost power
steering assistance. Refer to “Warning Lights And Mes-
sages” in “Getting To Know Your Instrument Panel” for
further information.

If the “POWER STEERING SYSTEM HOT - PERFOR-
MANCE MAY BE LIMITED” message and an icon are
displayed on the instrument cluster display screen, it
indicates that extreme steering maneuvers may have oc-
curred, which caused an over temperature condition in the
power steering system. You will lose power steering assis-
tance momentarily until the over temperature condition no
longer exists. Once driving conditions are safe, then pull
over and let vehicle idle for a few moments until the light
turns off. Refer to “Warning Lights And Messages” in
“Getting To Know Your Instrument Panel” for further
information.

286

STARTING AND OPERATING

NOTE:
• Even if the power steering assistance is no longer

operational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.

• If the condition persists, see your authorized dealer for

service.

STOP/START SYSTEM

The Stop/Start function was developed to reduce fuel
consumption. The system will stop the engine automati-
cally during a vehicle stop if the required conditions are
met. Releasing the brake pedal or pressing the accelerator
pedal will automatically restart the engine.

This vehicle has been upgraded with a Heavy Duty Battery,
Starter, as well as other engine parts, to handle the Addi-
tional engine starts.

Automatic Mode

The Stop/Start feature is enabled after every normal cus-
tomer engine start. At that time, the system will go into
STOP/START READY and if all other conditions are met,
can go into a STOP/START AUTOSTOP ACTIVE “Au-
tostop” mode.

To Activate The Autostop Mode, The Following Must
Occur:
• The system must be in STOP/START READY state. A

STOP/START READY message will be displayed in the
instrument cluster display within the Stop/Start section.
Refer to “Warning Lights And Messages” in “Getting To
Know Your Instrument Panel” for further information.

• The vehicle must be completely stopped.
• The gear selector must be in a forward gear and the

brake pedal depressed.

The engine will shut down, the tachometer will move to
the zero position and the Stop/Start telltale will illuminate
indicating you are in Autostop. Customer settings will be
maintained upon return to an engine running condition.

STARTING AND OPERATING

287

Possible Reasons The Engine Does Not Autostop

Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
