2016 JEEP CHEROKEE warning light

Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer condition. En-
gine 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
the intended path, ESC applies the brake of the appro-
priate 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 “ESC Activation/Malfunction Indicator Light” lo-
cated in the instrument cluster will start to flash as soon
as the ESC system becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes when the TCS
is active. If the “ESC Activation/Malfunction 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.
WARNING!
•
Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or

the “ESC Off Indicator Light” will illuminate, and the
“ESC OFF” message will display in the Electronic Vehicle
Information Center (EVIC). To turn ESC ON again,
momentarily push the “ESC Off” switch.
NOTE:System may switch from ESC Full Off to Partial
mode when vehicle exceeds a predetermined speed.
When the vehicle speed slows below the predetermined
speed the system will return to ESC Full Off.
ESC modes may also be affected by drive modes – if
equipped.
WARNING!
• In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled.
Therefore, enhanced vehicle stability offered by
the ESC system is unavailable. In an emergency

evasive maneuver, the ESC system will not engage
to assist in maintaining stability. “ESC Off” mode
is intended for off-highway or off-road use only.
• With the ESC switched off, the enhanced vehicle
stability offered by ESC is unavailable. In an
emergency evasive maneuver, the ESC system will
not engage to assist in maintaining stability. “Full

The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the ON
position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator

follow the trailer tongue weight recommendations. Refer
to “Trailer Towing” in this section for further informa-
tion. When TSC is functioning, the “ESC Activation/
Malfunction Indicator Light” will flash, the engine power
may be reduced and you may feel the brakes being
applied to individual wheels to attempt to stop the trailer
from swaying. TSC is disabled when the ESC system is in
the “Partial Off” or “Full Off” modes.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to
reach full braking during emergency braking situations.
It anticipates when an emergency braking situation mayoccur by monitoring how fast the throttle is released by
the driver. The EBC will prepare the brake system for a
panic stop.
Rainy Brake Support (RBS)
Rainy Brake Support may improve braking performance
in wet conditions. It will periodically apply a small
amount of brake pressure to remove any water buildup
on the front brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When Rainy Brake
Support is active, there is no notification to the driver and
no driver interaction is required.
Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the ESC and EPS
modules that provides torque at the steering wheel for
certain driving conditions in which the ESC module is
detecting vehicle instability. The torque that the steering
wheel receives is only meant to help the driver realize
optimal steering behavior in order to reach/maintain

WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have a collision resulting
in serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressures. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. Refer to the paragraph on
“Tread Wear Indicator”. Refer to the Tire and Loading Information placard or the Vehicle Certification Label for
the size designation of your tire. The Load Index and
Speed Symbol for your tire will be found on the original
equipment tire sidewall. See the Tire Sizing Chart ex-
ample found in the “Tire Safety Information” section of
this manual for more information relating to the Load
Index and Speed Symbol of a tire.
It is recommended to replace the two front tires or two
rear tires as a pair. Replacing just one tire can seriously
affect your vehicle’s handling. If you ever replace a
wheel, make sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact your authorized tire
dealer or original equipment dealer with any questions
you may have on tire specifications or capability. Failure
to use equivalent replacement tires may adversely affect
the safety, handling, and ride of your vehicle.

STARTING AND OPERATING 563

CAUTION!
Proper operation of four-wheel drive vehicles de-
pends on tires of equal size, type and circumference
on each wheel. Any difference in tire size can cause
damage to the power transfer unit. Tire rotation
schedule should be followed to balance tire wear.
TIRE PRESSURE MONITOR SYSTEM (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
The tire pressure will vary with temperature by approxi-
mately 1 psi (7 kPa) for every 12°F (6.5°C). This means
that when the outside temperature decreases, the tire
pressure will decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven forat least three hours, or driven less than 1 mile (1.6 km)
after a three hour period. The cold tire inflation pressure
must not exceed the maximum inflation pressure molded
into the tire sidewall. Refer to “Tires – General Informa-
tion” in “Starting And Operating” for information on
how to properly inflate the vehicle’s tires. The tire
pressure will also increase as the vehicle is driven. This is
normal and there should be no adjustment for this
increased pressure.
The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low-pressure warning
limit for any reason, including low temperature effects
and natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold placard pressure. Once the low tire pressure warn-
ing (Tire Pressure Monitoring Telltale Light) illuminates,
5
STARTING AND OPERATING 569

you must increase the tire pressure to the recommended
cold placard pressure in order for the “Tire Pressure
Monitoring Telltale Light” to turn off.
NOTE:When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.
The system will automatically update and the “Tire
Pressure Monitoring Telltale Light” will turn off once the
system receives the updated tire pressures. 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 informa-
tion.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of 33
psi (227 kPa). If the ambient temperature is 68°F (20°C) and
the measured tire pressure is 28 psi (193 kPa), a tempera-
ture drop to 20°F (-7°C) will decrease the tire pressure to approximately 24 psi (165 kPa). This tire pressure is low
enough to turn ON the “Tire Pressure Monitoring Telltale
Light.” Driving the vehicle may cause the tire pressure to
rise to approximately 28 psi (193 kPa), but the “Tire
Pressure Monitoring Telltale Light” will still be on. In this
situation, the “Tire Pressure Monitoring Telltale Light” will
turn off only after the tires are inflated to the vehicle’s
recommended cold placard pressure value.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.
CAUTION!
• The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size

equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage.
• Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your
vehicle to an authorized dealership to have your
sensor function checked.
• After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the TPMS sensor. NOTE:
•
The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
• Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underin-
flation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping
ability.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if underinflation has not reached the level
to trigger illumination of the “Tire Pressure Monitor-
ing Telltale Light”.

STARTING AND OPERATING 571

•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Premium System — If Equipped
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 the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors •
Various Tire Pressure Monitoring System messages,
which display in the Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID).
• Tire Pressure Monitoring Telltale LightTire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime
will sound when tire pressure is low in one or more of the
four active road tires. In addition, the Electronic Vehicle
Information Center (EVIC)/Driver information Display
(DID) will display a Tire Lowmessage for a minimum
of five seconds, an Inflate to XXmessage and a graphic
showing the pressure values of each tire with the low tire
pressure values in a different color.
