2016 JEEP GRAND CHEROKEE charging

control all the way down, to the 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 vehi-
cle’s battery.
The brightness of the instrument panel lighting can be
regulated by rotating the dimmer control up (brighter) or
down (dimmer). When the headlights are on you can
supplement the brightness of the DID, radio and over-
head console by rotating the control to its farthest posi-
tion up until you hear a click. This feature is termed the
“Parade” mode and is useful when headlights are re-
quired during the day.
Lights-On Reminder
If the headlights, parking lights, or cargo lights are left on
after the ignition is turned OFF, a chime will sound when
the driver ’s door is opened.

stop the vehicle and shut off the engine as soon as possible.
Battery Charge Warning Light
Red Telltale
Light What It Means
Battery Charge Warning Light
This light illuminates when the battery is not charging properly. If it stays on while the
engine is running, there may be a malfunction with the charging system. Contact your
authorized dealer as soon as possible. This indicates a possible problem with the electrical
system or a related component.

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
Electronic Vehicle Information Center (EVIC) or Driver
Information Display (DID).
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 “Understanding
Your Instrument Panel” for further information.

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
• Heated/Cooled Cup Holders — If Equipped
• Rear Defroster And Heated Mirrors
• HVAC System
• 115V 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 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, 115V AC, USB ports)
during certain driving conditions (city driving, tow-
ing, frequent stopping).
• Installing options like additional lights, upfitter elec-
trical 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.

1. Set the parking brake, shift the automatic transmissioninto PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri- cal accessories.
3. Remove the protective cover over the remote positive (+) battery post. Pull upward on the cover to remove
it.
4. If using another vehicle to jump-start the battery, park the vehicle within the jumper cables reach, set the
parking brake and make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this jump-starting procedure could
result in personal injury or property damage due to
battery explosion.
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.
616 WHAT TO DO IN EMERGENCIES

CAUTION!
Do not run the booster vehicle engine above 2000 rpm
since it provides no charging benefit, wastes fuel and
can damage booster vehicle engine.
6. Once the engine is started, remove the jumper cablesin 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 dis-
charged 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 your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets
draw power from the vehicle’s battery, even when not
in use (i.e., cellular devices, etc.). Eventually, if
plugged in long enough without engine operation,
the vehicle’s battery will discharge sufficiently to
degrade battery life and/or prevent the engine from
starting.
