If the windshield or Automatic High Beam Headlamp
Control mirror is replaced, the mirror must be re-aimed to
ensure proper performance. See your local authorized
dealer.
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 cancelled 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.

Malfunction Indicator Light will be continuously illumi-
nated. If the message appears and you can not start the
engine, we recommend you have your vehicle towed to
your nearest authorized dealer immediately.
NOTE:
• The gauge may take up to five seconds to update after
adding a gallon or more of Diesel Exhaust Fluid (DEF) to
the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See
your authorized dealer for service.
• The DEF gauge may also not immediately update after a
refill if the temperature of the DEF fluid is below 12F
(-11C). The DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update after a period
of run time. Under very cold conditions, it is possible
that the gauge may not reflect the new fill level for
several drives.
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 And Indicator
146 GETTING TO KNOW YOUR INSTRUMENT PANEL

Lights And Messages” located in ”Getting To Know
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, 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)4

WARNING!
•Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is ON. You can be injured by moving fan
blades.
• Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
NOTE: Be sure that the disconnected ends of the cables do
not touch while still connected to the either vehicle.
1. Set the parking brake, shift the automatic transmission into PARK and turn the ignition to OFF/LOCK.
2. Turn off the heater, radio, and all unnecessary electrical 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.
426 IN CASE OF EMERGENCY

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.
WARNING!
Do not connect the jumper cable to the negative (-) post
of the discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury. Only use the specific ground point, do
not use any other exposed metal parts.
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.
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 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.

IN CASE OF EMERGENCY 427

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.
REFUELING IN EMERGENCY
The funnel for the Cap-Less Fuel System is located in the
spare tire storage area. If your vehicle is out of fuel and an
auxiliary fuel can is needed, insert the funnel into the filler
neck and proceed to fill the vehicle.
For more information on the Cap-Less Fuel System refer to
“Refueling The Vehicle” in “Starting And Operating ” in
this manual.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
•On the highways — slow down.
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase the engine idle speed
while preventing vehicle motion with the brakes.
NOTE: There are steps that you can take to slow down an
impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine cooling system.
