HANDS-FREE LIFTGATE — IF EQUIPPED

Hands-Free Liftgate Activation Zone
To open or close the liftgate using hands-free
activation, use a straight in and out kicking motion
under the vehicle activation zone in the general
location below the rear license plate. The activation
zone is about 1.8 ft (0.5 m) from side to side. Do not
move your foot sideways or in a sweeping motion or
the sensors may not detect the motion.

NOTE:The activation zone is the same for vehicles
equipped with or without a trailer tow package.
When a valid kicking motion is completed, the
liftgate will chime, the hazard lights will flash and
the liftgate will open after approximately one
second, or close after approximately three
seconds. These settings can be enabled or
disabled through Uconnect Settings Ú page 204.

NOTE:
Opening or closing the Hands-Free Liftgate
requires a valid Passive Entry key fob within 5 ft
(1.5 m) of the liftgate handle. If a valid Passive
Entry key fob is not within 5 ft (1.5 m), the lift -
gate will not respond to any kicks.
The Hands-Free Liftgate feature may be turned
on or off through the Uconnect system
Ú page 204.
The Hands-Free Liftgate feature should be
turned off during jacking, tire changing, manual
car wash, and vehicle service.
The Hands-Free Liftgate feature can be acti -
vated by any metallic object making a similar
in-and-out motion under the rear fascia/
bumper, such as cleaning using a metal broom.
The Hands-Free Liftgate will only operate when
the transmission is in PARK.
If anything obstructs the Hands-Free Liftgate
while it is opening or closing, the liftgate will
automatically reverse to the closed/open posi -
tion, provided it meets sufficient resistance.
There are pinch sensors attached to the side of
the liftgate opening. Light pressure anywhere
along these strips will cause the liftgate to
return to the open position.
If the power liftgate encounters multiple
obstructions within the same cycle, the system
will automatically stop. If this occurs, the liftgate
must be operated manually.
The power liftgate will release, but not power
open, in temperatures below −12°F (−24°C).
Be sure to remove any buildup of snow or ice
from the liftgate before opening the liftgate.
If the liftgate is left open for an extended period
of time (approximately one hour), the liftgate
may need to be closed manually to reset power
liftgate functionality. Gas props support the liftgate in the open position.
However, because the gas pressure drops with
temperature, it may be necessary to assist the
props when opening the liftgate in cold weather.
NOTE:Allow the power system to open the liftgate.
Manually pushing or pulling the liftgate may
activate the liftgate obstacle detection feature and
stop the power operation or reverse its direction.

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.

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

If a problem is detected while the vehicle
is running, the light will either stay on or
flash depending on the nature of the problem.
Cycle the ignition when the vehicle is safely and
completely stopped and the transmission is placed
in the PARK position. The light should turn off. If
the light remains on with the vehicle running, your
vehicle will usually be drivable; however, see an
authorized dealer for service as soon as possible.
NOTE:This light may turn on if the accelerator and brake
pedals are pressed at the same time.
If the light continues to flash when the vehicle is
running, immediate service is required and you
may experience reduced performance, an
elevated/rough idle, or engine stall and your
vehicle may require towing. The light will come on
when the ignition is placed in the ON/RUN position
and remain on briefly as a bulb check. If the light
does not come on during starting, have the system
checked by an authorized dealer.
Engine Coolant Temperature Warning
Light
This warning light warns of an
overheated engine condition. If the
engine coolant temperature is too high,
this indicator will illuminate and a single
chime will sound. If the temperature reaches the
upper limit, a continuous chime will sound for four
minutes or until the engine is able to cool;
whichever comes first.
If the light turns on while driving, safely pull over
and stop the vehicle. If the Air Conditioning (A/C)
system is on, turn it off. Also, shift the transmission
into NEUTRAL (N) and idle the vehicle. If the
temperature reading does not return to normal,
