90GETTING TO KNOW YOUR VEHICLE
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.
CARGO AREA FEATURES
Cargo Storage
The load floor is designed for a maximum load of
300 lb (136 kg).
If equipped, there may be a removable storage bin
located on the left side of the rear cargo area.
WARNING!
Driving with the liftgate open can allow
poisonous exhaust gases into your vehicle.
You and your passengers could be injured by
these fumes. Keep the liftgate closed when
you are operating the vehicle.
If you are required to drive with the liftgate
open, make sure that all windows are closed,
and the climate control blower switch is set at
high speed. Do not use the recirculation
mode.
WARNING!
During power operation, personal injury or cargo
damage may occur. Ensure the liftgate travel
path is clear. Make sure the liftgate is closed
and latched before driving away.

108GETTING TO KNOW YOUR INSTRUMENT PANEL
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
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
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have
failed. It will take longer to stop the vehicle. You
could have a collision. Have the vehicle checked
immediately.

23_WL_OM_EN_USC_t.book Page 108

GETTING TO KNOW YOUR INSTRUMENT PANEL109
applied or a brake fault is detected. If the light does
not illuminate, have the light inspected by an
authorized dealer.
The light also will turn on when the parking brake
is applied with the ignition switch in the ON/RUN
position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake appli -
cation.
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.
Door Open Warning Light
This indicator will illuminate when a door
is ajar/open and not fully closed.
NOTE:If the vehicle is moving, there will also be a single
chime.
Electric Power Steering (EPS) Fault
Warning Light
This warning light will turn on when
there's a fault with the EPS system
Ú page 139.
Electronic Throttle Control (ETC) Warning
Light
This warning light will illuminate to
indicate a problem with the ETC system.
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,
turn the engine off immediately and call for service
Ú page 322.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.
