2023 JEEP GRAND CHEROKEE warning lights

GETTING TO KNOW YOUR VEHICLE59
On some vehicles, the Daytime Running Lights
may deactivate, or reduce intensity, on one side
of the vehicle (when a turn signal is activated on
that side), or on both sides of the vehicle (when
the hazard warning lights are activated).
HIGH/LOW BEAM SWITCH
Push the multifunction lever toward the instrument
panel to switch the headlights to high beams.
Pulling the multifunction back toward the steering
wheel will turn the low beams back on, or shut the
high beams off.
AUTOMATIC HIGH BEAMS —
I
F EQUIPPED
The Automatic High Beam Headlight system
provides increased forward lighting at night by
automating high beam control through the use of a
digital camera mounted on the inside rearview
mirror. This camera detects vehicle specific light
and automatically switches from high beams to low
beams until the approaching vehicle is out of view.
NOTE:
The Automatic High Beam Headlight system can
be turned on or off by selecting or deselecting
“Auto Dim High Beams” within Uconnect
Settings Ú page 204.
The headlight switch must also be turned to the
AUTO position after Automatic High Beams is
enabled within Uconnect Settings for the
feature to activate.
Automatic High Beams will only activate when
the vehicle speed is above 22 mph (35 km/h).
Broken, muddy, or obstructed headlights and
taillights of vehicles in the field of view will
cause headlights to remain on longer (closer to
the vehicle). Also, dirt, film, and other obstruc -
tions on the windshield or camera lens will
cause the system to function improperly.
If the windshield or Automatic High Beam
Headlight Control mirror is replaced, the mirror
must be re-aimed to ensure proper performance.
See a local authorized dealer.
FLASH-TO-PASS
You can signal another vehicle with your headlights
by lightly pulling the multifunction lever toward you.
This will cause the high beam headlights to turn on,
and remain on, until the lever is released.
AUTOMATIC HEADLIGHTS
This system automatically turns the headlights on
or off according to ambient light levels. To turn the
system on, rotate the headlight switch
counterclockwise to the AUTO position. When the
system is on, the headlight time delay feature is
also on. This means the headlights will stay on for up to 90 seconds after you place the ignition into
the OFF position. The headlight time delay can be
programmed to 0/30/60/90 seconds within the
Uconnect system Ú
page 204.
To turn the automatic system off, move the
headlight switch out of the AUTO position.
NOTE:The engine must be running before the headlights
will come on in the automatic mode.
PARKING LIGHTS AND PANEL LIGHTS
To turn on the parking lights and instrument panel
lights, rotate the headlight switch clockwise. To
turn off the parking lights, rotate the headlight
switch back to the O (off) position.
NOTE:Vehicles sold in Canada are equipped with a head -
light switch with an AUTO and ON detent but
without an OFF detent. Headlights will be deacti -
vated when the headlight switch is placed in the
parking lights position. However, the Daytime
Running Lights (DRLs) will be activated along with
the front and rear marker lights. The DRLs may be
deactivated when the parking brake is engaged.

POWER INVERTER — IF EQUIPPED
There is a 115 Volt, 150 W inverter outlet located
on the back of the center console to convert DC
current to AC current. This outlet can power cellular
phones, electronics and other low power devices
requiring power up to 150 W. Certain video game
consoles exceed this power limit, as will most
power tools.
Power Inverter

The power inverter is designed with built-in
overload protection. If the power rating of 150 W is
exceeded, the power inverter automatically shuts
down. Once the electrical device has been
removed from the outlet the inverter should
automatically reset. To avoid overloading the
circuit, check the power ratings on electrical
devices prior to using the inverter.
WIRELESS CHARGING PAD —
I
F EQUIPPED

Wireless Charging Pad

Your vehicle may be equipped with a 15 W3 Amp
Qi wireless charging pad located inside of the
storage area below the climate controls. This
charging pad is designed to wirelessly charge your
Qi enabled mobile phone. Qi is a standard that
allows wireless charging of your mobile phone.
Your mobile phone must be designed for Qi
wireless charging. If the phone is not equipped
with Qi wireless charging functionality, an
aftermarket sleeve or a specialized back plate can
be purchased from your mobile phone provider or
a local electronics retailer. Please see your
phone’s owner’s manual for further information.
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 accessories,
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
battery.
CAUTION!
WARNING!
To avoid serious injury or death:
Do not insert any objects into the receptacles.
Do not touch with wet hands.
Close the lid when not in use.
If this outlet is mishandled, it may cause an
electric shock and failure.

When load reduction is activated, the message
“Battery Saver On” or “Battery Saver Mode” will
appear in the instrument cluster.
These messages indicate the vehicle battery has a
low state of charge and continues to lose electrical
charge at a rate that the charging system cannot
sustain.
NOTE:
The charging system is independent from load
reduction. The charging system performs a diag -
nostic on the charging system continuously.
If the Battery Charge Warning Light is on it may
indicate a problem with the charging system
Ú page 109.
The electrical loads that may be switched off (if
equipped), and vehicle functions which can be
affected by load reduction:
Heated Seat/Vented Seats/Heated Wheel
Rear Defroster And Heated Mirrors
HVAC System
115 Volt AC Power Inverter System
Audio and Telematics System Loss of the battery charge may indicate one or
more of the following conditions:
The charging system cannot deliver enough
electrical power to the vehicle system because
the electrical loads are larger than the capability
of the charging system. The charging system is
still functioning properly.
Turning on all possible vehicle electrical loads
(e.g. HVAC to max settings, exterior and interior
lights, overloaded power outlets +12 Volt, 115
Volt AC, USB ports) during certain driving condi
-
tions (city driving, towing, frequent stopping,
etc.).
Installing options like additional lights, upfitter
electrical accessories, audio systems, alarms
and similar devices.
Unusual driving cycles (short trips separated by
long parking periods).
The vehicle was parked for an extended period
of time (weeks, months).
The battery was recently replaced and was not
charged completely.
The battery was discharged by an electrical load
left on when the vehicle was parked.
The battery was used for an extended period
with the engine not running to supply radio,
lights, chargers, +12 Volt portable appliances
like vacuum cleaners, game consoles and
similar devices. What to do when an electrical load reduction
action message is present (“Battery Saver On” or
“Battery Saver Mode”)
During a trip:
Reduce power to unnecessary loads if possible:
Turn off redundant lights (interior or exte
-
rior)
Check what may be plugged in to power
outlets +12 Volt, 115 Volt AC, USB ports
Check HVAC settings (blower, temperature)
Check the audio settings (volume)
After a trip:
Check if any aftermarket equipment was
installed (additional lights, upfitter electrical
accessories, audio systems, alarms) and review
specifications if any (load and Ignition Off Draw
currents).
Evaluate the latest driving cycles (distance,
driving time and parking time).
The vehicle should have service performed if
the message is still present during consecutive
trips, and if the evaluation and driving pattern of
the vehicle did not help to identify the cause.

WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated
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
carefully in all cases. Always refer to the
information in this chapter in the event of a failure
indication. All active telltales will display first if
applicable. The system check menu may appear
different based upon equipment options and
current vehicle status. Some telltales are optional
and may not appear.
RED WARNING LIGHTS
Active Driving Assist - Driver
Inattentiveness Warning Light
This light illuminates when driver
inattentiveness has been continually
detected, warning the driver to place
their hands on the steering wheel.
Air Bag Warning Light
This warning light will illuminate to
indicate a fault with the air bag, and will
turn on for four to eight seconds as a bulb
check when the ignition is placed in the
ON/RUN position. This light will illuminate with a single chime when a fault with the air bag has been
detected, it will stay on until the fault is cleared. If
the light is either not on during startup, stays on, or
turns on while driving, have the system inspected
at an authorized dealer as soon as possible.
Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake
light turns on it may indicate that the
parking brake is applied, that the brake fluid level
is low, or that there is a problem with the Anti-Lock
Brake System reservoir.
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 hydraulic system malfunction or
that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS) /
Electronic Stability Control (ESC) system. In this
case, the light will remain on until the condition 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 indicated by the Brake Warning
Light, which will turn on when the brake fluid level in the master cylinder has dropped below a
specified 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.
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 approximately two seconds. The light
should then turn off unless the parking brake is
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.
