warning light JEEP GRAND CHEROKEE LIMITED 2017 Owners Manual

WARNING!
•Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns even
at low temperatures, especially if used for long
periods of time
• Do not place anything on the seat or seatback that
insulates against heat, such as a blanket or cushion.
This may cause the seat heater to overheat. Sitting in
a seat that has been overheated could cause serious
burns due to the increased surface temperature of the
seat.
Rear Heated Seats — If Equipped
On some models, the two rear outboard seats may be
equipped with heated seats. There are two heated seat
switches that allow the rear passengers to operate the seats
independently. The heated seat switches for each heater are
located on the rear of the center console. You can choose from HI, LO, or OFF heat settings. Amber
indicator lights in each switch indicate the level of heat in
use. Two indicator lights will illuminate for HI, one for LO
and none for OFF.
Push the switch once to select HI-level heating. Push the
switch a second time to select LO-level heating. Push the
switch a third time to shut the heating elements off.
When the HI-level setting is selected, the heater will
provide a boosted heat level during the first four minutes
of operation. Then, the heat output will drop to the normal
HI-level. If the HI-level setting is selected, the system will

clear. Make sure the liftgate is closed and latched
before driving away.
NOTE:
• The power liftgate buttons will not operate if the vehicle
is in gear or the vehicle speed is above 0 MPH (0 km/h).
• The power liftgate will not operate in temperatures
below 22°F (30°C) or temperatures above 150° F (65°
C). Be sure to remove any buildup of snow or ice from
the liftgate before pushing any of the power liftgate
switches.
• If anything obstructs the power liftgate while it is
closing or opening, the liftgate will automatically re-
verse to the closed or open position, provided it meets
sufficient resistance.
• There are also pinch sensors attached to the side of the
liftgate. Light pressure anywhere along these strips will
cause the liftgate to return to the open position.
• If the liftgate is not fully open, push the liftgate button
on the key fob twice to operate the liftgate. •
If the electronic liftgate release is pushed while the
power liftgate is closing, the liftgate will reverse to the
full open position.
• If the electronic liftgate release is pushed while the
power liftgate is opening, the liftgate motor will disen-
gage to allow manual operation.
• If the power liftgate encounters multiple obstructions
within the same cycle, the system will automatically
stop and the liftgate must be opened or closed manually.

WARNING!(Continued)
•Do not pile luggage or cargo higher than the top of
the seatback. This could impair visibility or become
a dangerous projectile in a sudden stop or accident.
GARAGE DOOR OPENER — IF EQUIPPED
HomeLink replaces up to three hand-held transmitters that
operate devices such as garage door openers, motorized
gates, lighting or home security systems. The HomeLink
unit is powered by your vehicle’s 12 Volt battery.
The HomeLink buttons, located on the overhead console,
designate the three different HomeLink channels. The
HomeLink indicator is located above the center button. NOTE:
HomeLink is disabled when the Vehicle Security
Alarm is active.

WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required. Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.

WARNING!(Continued)
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user ’s safety or the safety of
others.
ABS is designed to function with the OEM tires. Modifica-
tion may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake 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 “Anti-Lock Brake Warning Light” remains on or
comes on while driving, it indicates that the anti-lock
portion of the brake system is not functioning and that
service is required. However, the conventional brake sys-
tem will continue to operate normally if the “Brake System
Warning Light” is not on.
If the “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “Anti-Lock Brake Warning
Light” does not come on when the ignition is turned to the
ON/RUN mode, have the light repaired as soon as possible.
Electronic Brake Control System
Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Hill Start Assist
(HSA), Traction Control System (TCS), Electronic Stability
Control (ESC), and Electronic Roll Mitigation (ERM). These
systems work together to enhance both vehicle stability
and control in various driving conditions.
Your vehicle may also be equipped with Trailer Sway
Control (TSC), Ready Alert Braking (RAB), Rain Brake
Support (RBS), Dynamic Steering Torque (DST), Hill De-
scent Control (HDC), and Selec-Speed Control (SSC).
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.

SAFETY 179

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-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 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!(Continued)
•Vehicle modifications, or failure to properly main-
tain your vehicle, may change the handling charac-
teristics of your vehicle, and may negatively affect
the performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly
worn tires may also degrade ESC performance. Any
vehicle modification or poor vehicle maintenance
that reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.
ESC Operating Modes
NOTE: Depending upon model and mode of operation, the
ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions.
Alternate ESC modes should only be used for specific
reasons as noted in the following paragraphs. Partial Off
The “Partial Off” mode is intended for times when a more
spirited driving experience is desired. This mode may
modify TCS and ESC thresholds for activation, which
allows for more wheel spin than normally allowed. This
mode may be useful if the vehicle becomes stuck.
To enter the “Partial Off” mode, momentarily push the
“ESC Off” switch and the “ESC Off Indicator Light” will
illuminate. To turn the ESC on again, momentarily push
the “ESC Off” switch and the “ESC Off Indicator Light”
will turn off.
NOTE:
For vehicles with multiple partial ESC modes a
momentary button push will toggle the ESC mode. Mul-
tiple momentary button pushed may be required to return
to ESC On.

WARNING!(Continued)
feature of TCS is disabled, and the enhanced vehicle
stability offered by the ESC system is reduced.
• Trailer Sway control (TSC) is disabled when the ESC
system is in the “Partial Off” mode.
Full Off — If Equipped
This mode is intended for off-highway or off-road use only
and should not be used on any public roadways. In this
mode, TCS and ESC features are turned OFF. To enter the
“Full Off” mode, push and hold the “ESC Off” switch for five
seconds while the vehicle is stopped with the engine run-
ning. After five seconds, a chime will sound, the “ESC Off
Indicator Light” will illuminate, and the “ESC OFF” message
will display in the instrument cluster. To turn ESC ON again,
momentarily push the “ESC Off” switch.
NOTE: System may switch from ESC “Full Off” to “Partial
Off” mode when vehicle exceeds a predetermined speed.
When the vehicle speed slows below the predetermined
speed the system will return to ESC “Full Off”.
“Full Off” can only be achieved in Track Mode if so
equipped.
ESC modes may also be affected by drive modes if so
equipped.

have the system inspected at an authorized dealer as
soon as possible. This light will illuminate with a single
chime when a fault with the Air Bag Warning Light has
been detected, it will stay on until the fault is cleared. If
the light comes on intermittently or remains on while
driving, have an authorized dealer service the vehicle
immediately. Refer to “Occupant Restraint Systems” in
“Safety” for further information.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is inoper-
able.
Floor Mat Safety Information
Always use floor mats designed to fit your vehicle. Only
use a floor mat that does not interfere with the operation of
the pedal assemblies. Only use a floor mat that is securely
attached using the floor mat fasteners so it cannot slip out
of position and interfere with the pedal assemblies or
impair safe operation of your vehicle in other ways.
