charging JEEP GRAND CHEROKEE LIMITED 2019 Owners Manual

Turn Signals
Move the multifunction lever up or down and the arrows
on each side of the instrument cluster flash to show proper
operation of the front and rear turn signal lights.
NOTE:If either light remains on and does not flash, or
there is a very fast flash rate, check for a defective outside
light bulb. If an indicator fails to light when the lever is
moved, it would suggest that the indicator bulb is defec-
tive.
Lane Change Assist — If Equipped
Tap the multifunction lever up or down once, without
moving beyond the detent, and the turn signal (right or
left) will flash three times then automatically turn off.
Battery Saver
To protect the life of your vehicle’s battery, load shedding
is provided for both the interior and exterior lights.
If the ignition is OFF and any door is left ajar for 10 minutes
or the dimmer control is rotated all the way up to the dome
on position for 10 minutes, the interior lights will automati-
cally turn off. NOTE:
Battery saver mode is canceled if the ignition is
ON.
If the headlights remain on while the ignition is cycled OFF,
the exterior lights will automatically turn off after eight
minutes. If the headlights are turned on and left on for
eight minutes while the ignition is OFF, the exterior lights
will automatically turn off.
INTERIOR LIGHTS
Courtesy and dome lights are turned on when the front
doors are opened or when the dimmer control (rotating
wheel on the right side of the headlight switch) is rotated
to its farthest upward position. If your vehicle is equipped
with remote keyless entry and the unlock button is pushed
on the key fob, the courtesy and dome lights will turn on.
When a door is open and the interior lights are on, rotating
the dimmer control all the way down, to the last (off)
detent, will cause all the interior lights to go out. This is
also known as the “Party” mode because it allows the
doors to stay open for extended periods of time without
discharging the vehicle’s battery.

Battery Saver On/Battery Saver Mode Message —
Electrical Load Reduction Actions (If Equipped)
This vehicle is equipped with an Intelligent Battery Sensor
(IBS) to perform additional monitoring of the electrical
system and status of the vehicle battery.
In cases when the IBS detects charging system failure, or
the vehicle battery conditions are deteriorating, electrical
load reduction actions will take place to extend the driving
time and distance of the vehicle. This is done by reducing
power to or turning off non-essential electrical loads. Load reduction is only active when the engine is running.
It will display a message if there is a risk of battery
depletion to the point where the vehicle may stall due to
lack of electrical supply, or will not restart after the current
drive cycle.
When load reduction is activated, the message “Battery
Saver On” or “Battery Saver Mode” will appear in the
instrument cluster display.
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 reduc-
tion. The charging system performs a diagnostic on the
charging system continuously.
• If the Battery Charge Warning Light is on it may indicate
a problem with the charging system. Refer to “Battery
Charge Warning Light” in “Warning Lights And Mes-
sages” located in ”Getting To Know Your Instrument
Panel” for further information.
146 GETTING TO KNOW YOUR INSTRUMENT PANEL

The electrical loads that may be switched off (if equipped),
and vehicle functions which can be effected by load
reduction:
•Heated Seat/Vented Seats/Heated Wheel
• Rear Defroster And Heated Mirrors
• HVAC System
• 150W 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 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 +12V, 150W, USB ports) dur-
ing certain driving conditions (city driving, towing,
frequent stopping).
• Installing options like additional lights, upfitter electri-
cal accessories, audio systems, alarms and similar de-
vices. •
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,
+12V portable appliances like vacuum cleaner ’s, 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 exterior)
– Check what may be plugged in to power outlets +12V, 150W, USB ports
– Check HVAC settings (blower, temperature)
– Check the audio settings (volume)

4. If using another vehicle to jump start the battery, parkthe vehicle within the jumper cables reach, apply the
parking brake and make sure the ignition is OFF.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
NOTE: Make sure at all times that unused ends of jumper
cables are not contacting each other or either vehicle while
making connections. Connecting The Jumper Cables
1. Connect the positive
(+)end of the jumper cable to the
remote positive (+)post of the discharged vehicle.
2. Connect the opposite end of the positive (+)jumper
cable to the positive (+)post of the booster battery.
3. Connect the negative end (-)of the jumper cable to the
negative (-)post of the booster battery.
4. Connect the opposite end of the negative (-)jumper
cable to the remote negative (-)post of the vehicle with
the discharged battery.

CAUTION!
Do not run the booster vehicle engine above 2,000 rpm
since it provides no charging benefit, wastes fuel, and
can damage booster vehicle engine.
6. Once the engine is started, remove the jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative (-)end of the jumper cable from
the remote negative (-)post of the discharged vehicle.
2. Disconnect the opposite end of the negative (-)jumper
cable from the negative (-)post of the booster battery.
3. Disconnect the positive (+)end of the jumper cable from
the positive (+)post of the booster battery.
4. Disconnect the opposite end of the positive (+)jumper
cable from the remote positive (+)post of the discharged
vehicle.
5. Reinstall the protective cover over the remote positive (+) post of the discharged vehicle. If frequent jump starting is required to start your vehicle
you should have the battery and charging system tested at
an authorized dealer.
