warning light JEEP CHEROKEE 2019 Owner handbook (in English)

NOTE:
Activation zone is the same for vehicles
equipped with and without trailer tow package.
When a valid kicking motion is completed,
the liftgate will chime, the hazard lights will
flash and the liftgate will open after approxi-
mately one second, or close after approxi-
mately three seconds. This assumes all op-
tions are enabled in the radio.
NOTE:
• Opening or closing the Hands-Free Liftgate
requires a valid Passive Entry key fob within
5 ft (1.5 m) of the door handle. If a valid
Passive Entry key fob is not within 5 ft
(1.5 m), the liftgate will not respond to any
kicks.
• The Hands-Free Liftgate feature may be
turned on or off in Uconnect Settings. Refer
to “Uconnect Settings” in “Multimedia” in
the Owner’s Manual for further information.
The Hands-Free Liftgate feature should be
turned off during Jacking, Tire Changing,
Manual Car Wash, and Vehicle Service.NOTE:
The Hands-free liftgate feature can be acti-
vated by any metallic object making a similar
in-and-out motion under the rear bumper,
such as cleaning using a metal broom.
NOTE:
• The Hands-Free Liftgate will only operate
when the transmission is in PARK.
• If anything obstructs the Hands-Free lift-
gate while it is opening or closing, the
liftgate will automatically reverse to the
closed/open position, provided it meets
sufficient resistance.
• There are pinch sensors attached to the
side of the liftgate opening. Light pressure
anywhere along these strips will cause the
liftgate to return to the open position.
• If the power liftgate encounters multiple
obstructions within the same cycle, the
system will automatically stop. If this oc-
curs, the liftgate must be operated manu-
ally.• The power liftgate will release, but not
power open, in temperatures below −12° F
(−24° C). Be sure to remove any buildup of
snow or ice from the liftgate before opening
the liftgate.
• If the liftgate is left open for an extended
period of time, the liftgate may need to be
closed manually to reset power liftgate
functionality.
WARNING!
• Driving with the liftgate open can allow
poisonous exhaust gases into your ve-
hicle. You and your passengers could be
injured by these fumes. Keep the liftgate
closed when you are operating the ve-
hicle.
• If you are required to drive with the
liftgate open, make sure that all win-
dows are closed, and the climate control
blower switch is set at high speed. Do
not use the recirculation mode.

A third fused 12 Volt power outlet is located
on the left quarter trim panel in the cargo
area. This power outlet has power available
when the ignition switch is in the ON or ACC
position.NOTE:
The rear cargo power outlet can be changed
to “battery” powered all the time. Refer to an
authorized dealer.
WARNING!
To avoid serious injury or death:
• Only devices designed for use in this
type of outlet should be inserted into any
12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while
driving the vehicle.
• If this outlet is mishandled, it may cause
an electric shock and failure.
CAUTION!
• Many accessories that can be plugged in
draw power from the vehicle's battery,
even when not in use (i.e., cellular
phones, etc.). Eventually, if plugged in
long enough, the vehicle's battery will
discharge sufficiently to degrade battery
life and/or prevent the engine from start-
ing.
CAUTION!
• Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.)
will degrade the battery even more
quickly. Only use these intermittently
and with greater caution.
• After the use of high power draw acces-
sories, or long periods of the vehicle not
being started (with accessories still
plugged in), the vehicle must be driven a
sufficient length of time to allow the
generator to recharge the vehicle's bat-
tery.

WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
CAUTION!
The engine may be switched off even if the
warning light is on: repeated interruptions
of the regeneration process could cause an
early deterioration of engine oil. For this
reason it is always advisable to wait for the
symbol to go off before turning off the
engine, following the instructions above.
Do not complete the DPF regeneration
process when the vehicle is stopped.
WARNING LIGHTS AND
MESSAGES
The warning/indicator lights will illuminate in
the instrument panel together with a dedi-
cated message and/or acoustic signal when
applicable. These indications are indicative
and precautionary and as such must not be
considered as exhaustive and/or alternative
to the information contained in the Owner’s
Manual, which you are advised to read care-
fully in all cases. Always refer to the informa-
tion in this chapter in the event of a failure
indication. All active telltales will display first

brake is applied, that the brake fluid level is
low, or that there is a problem with the
anti-lock brake system.
If the light remains on when the parking
brake has been disengaged, and the fluid
level is at the full mark on the master cylinder
reservoir, it indicates a possible brake hy-
draulic system malfunction or that a problem
with the Brake Booster has been detected by
the Anti-Lock Brake System (ABS) / Elec-
tronic Stability Control (ESC) system. In this
case, the light will remain on until the condi-
tion has been corrected. If the problem is
related to the brake booster, the ABS pump
will run when applying the brake, and a brake
pedal pulsation may be felt during each stop.The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in
either half of the dual brake system is indi-
cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied level.
The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid
level conditions. The vehicle should have
service performed, and the brake fluid level
checked.
If brake failure is indicated, immediate repair
is necessary.
