traction control JEEP CHEROKEE 2015 KL / 5.G User Guide

• 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
4X4 LOW range. If 4X4 LOW shift conditions/interlocks are not met, a message will
flash from the Electronic Vehicle Information Center (EVIC)/Driver Information
Display with instructions on how to complete the requested shift.
SELEC-TERRAIN™
• Selec-Terrain™ combines the capa-
bilities of the vehicle control systems,
along with driver input, to provide the
best performance for all terrains.
Rotate the mode control knob to select
the following Selec-Terrain™ positions:
•Auto— Fully automatic full time four-
wheel drive operation can be used on
and off road. Balances traction with
seamless steering feel to provide im-
proved handling and acceleration over
two-wheel drive vehicles.
•Snow— Tuning set for additional sta-
bility 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.
•Sand/Mud— Off road calibration for use on low traction 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.
Activate the Hill Descent Control for steep downhill control. Use for low speed
obstacles such as large rocks, deep ruts, etc.
NOTE:
SPORT mode is not available when 4X4 LOW is selected.

CAUTION!
Prolonged driving with the Malfunction Indicator Light (MIL) on could cause
damage to the engine control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic converter damage and power
loss will soon occur. Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced above, can reach higher
temperatures than in normal operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such as dry plants, wood,
cardboard, etc. This could result in death or serious injury to the driver, occupants
or others.
– SERV (Service) 4WD Indicator Light
If the light stays on or comes on during driving, it means that the 4WD system is not
functioning properly and that service is required. We recommend you drive to the
nearest service center and have the vehicle serviced immediately.
-ElectronicStabilityControl(ESC)Activation/MalfunctionIndicatorLight
• If this indicator light flashes during acceleration, apply as little throttle as
possible. While driving, ease up on the accelerator. Adapt your speed and driving
to the prevailing road conditions. To improve the vehicle's traction when starting
off in deep snow, sand or gravel, it may be desirable to switch the ESC system off.
Oil Life Reset
• Your vehicle is equipped with an engine oil change indicator system. The “Oil
Change Due” message will flash in the EVIC display for approximately 10 seconds
after a single chime has sounded, to indicate the next scheduled oil change
interval. The engine oil change indicator system is duty cycle based, which means
the engine oil change interval may fluctuate, dependent upon your personal
driving style.
• Unless reset, this message will continue to display each time you turn the ignition
switch to the ON/RUN position or cycle the ignition to the ON/RUN position if
equipped with Keyless Enter-N-Go™. To turn off the message temporarily, push
and release the MENU button. To reset the oil change indicator system (after
performing the scheduled maintenance) refer to the following procedure:
Vehicles Equipped With Passive Entry
Without pushing the brake pedal, push the ENGINE START/STOP button and cycle
the ignition to the ON/RUN position (Do not start the engine.)
1. Push theOKbutton to enter the EVIC menu screen.

FREEING A STUCK VEHICLE
• If your vehicle becomes stuck in mud, sand or snow, it can often be moved by a
rocking motion. Turn your steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between REVERSE and DRIVE. Using
minimal accelerator pedal pressure to maintain the rocking motion, without
spinning the wheels, is most effective.
NOTE:
If your vehicle is equipped with Traction Control or Electronic Stability Control (ESC),
turn the system OFF before attempting to “rock” the vehicle.
CAUTION!
• Racing the engine or spinning the wheels may lead to transmission overheating
and failure. Allow the engine to idle with the shift lever in NEUTRAL for at least
one minute after every five rocking-motion cycles. This will minimize overheat-
ing and reduce the risk of transmission failure during prolonged efforts to free
a stuck vehicle.
• When “rocking” a stuck vehicle by moving between REVERSE and DRIVE, do
not spin the wheels faster than 15 mph (24 km/h), or drivetrain damage may
result.
• Revving the engine or spinning the wheels too fast may lead to transmission
overheating and failure. It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmission shifting occurring).
WARNING!
Fast spinning tires can be dangerous. Forces generated by excessive wheel speeds
may cause damage, or even failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without stopping when you are stuck
and do not let anyone near a spinning wheel, no matter what the speed.
