SENTRY KEY
The Sentry Key Immobilizer system prevents
unauthorized vehicle operation by disabling the
engine. The system does not need to be armed or
activated. Operation is automatic, regardless of
whether the vehicle is locked or unlocked. The system uses a key fob, keyless push button
ignition and a Radio Frequency (RF) receiver to
prevent unauthorized vehicle operation. Therefore,
only key fobs that are programmed to the vehicle
can be used to start and operate the vehicle. The
system cannot reprogram a key fob obtained from
another vehicle.
After placing the ignition switch in the ON/RUN
position, the Vehicle Security Light will turn on for
three seconds for a bulb check. If the light remains
on after the bulb check, it indicates that there is a
problem with the electronics. In addition, if the light
begins to flash after the bulb check, it indicates
that someone attempted to start the engine with
an invalid key fob. In the event that a valid key fob
is used to start the engine but there is an issue
with the vehicle electronics, the engine will start
and shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than
10 seconds), it indicates that there is a fault in the
electronics. Should this occur, have the vehicle
serviced as soon as possible by an authorized
dealer.
All of the key fobs provided with your new vehicle
have been programmed to the vehicle electronics
Ú
page 387.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
If applicable, refer to the “Hybrid Supplement”
for additional information.
This feature allows the driver to operate the
ignition switch with the push of a button as long as
the key fob is in the passenger compartment.
The START/STOP ignition button has four
operating positions; three of which are labeled and
will illuminate when in position. The three positions
are OFF, ACC, and ON/RUN. The fourth position is
START. During START, RUN will illuminate.
CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket Remote Start
systems. Use of these systems may result in
vehicle starting problems and loss of security
protection.

POWER INVERTER — IF EQUIPPED
There is a 115 Volt, 150 Watt Power Inverter outlet
located on the right side of the vehicle, before the
third row of seats to convert DC current to AC
current. The Power Inverter can power cellular
phones, electronics and other low power devices
requiring up to 150 Watts. Certain video game consoles will exceed this
power limit, as will most power tools.

Power Inverter

The Power Inverter turns on when the device is
plugged in, and the ignition is in ON/RUN position.
It turns off when the device is unplugged or the
ignition is no longer in ON/RUN position.
The Power Inverter is designed with built-in
overload protection. If the power rating of
150 Watts is exceeded, the Power Inverter shuts
down. Once the electrical device has been
removed from the Power Inverter, it resets. To
avoid overloading the circuit, check the power
ratings on electrical devices prior to using the
Power Inverter.
WIRELESS CHARGING PAD —
I
F EQUIPPED

Wireless Charging Pad Location

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.). Eventu -
ally, if plugged in long enough, the vehicle's
battery will discharge sufficiently to degrade
battery life and/or prevent the engine from
starting.
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.
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.

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 +12 Volts,
150W, USB ports) during certain driving condi -
tions (city driving, towing, frequent stopping).
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 Volts, 150W, 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).

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
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 or ACC/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.
Battery Charge Warning Light
This warning light will illuminate 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 an authorized dealer as soon as
possible.
This indicates a possible problem with the
electrical system or a related component.
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.
