Wireless Charging Pad — If Equipped
Wireless Charging PadYour vehicle may be equipped with a 15W 3A Qi wireless
charging pad located inside of the center console just below
the CD player (if equipped). This charging pad is designed to
wirelessly charge your Qi enabled mobile phone. Qi is a stan
-
dard that uses magnetic induction to transfer power to your
mobile device.
Your mobile phone must be designed for Qi wireless
charging. If the phone is not equipped with Qi wireless
charging functionality, an aftermarket sleeve or a specialized
back plate can be purchased from your mobile phone
provider or an local electronics retailer. Please see your
phone’s owner’s manual for further information.
The wireless charging pad is equipped with an anti-slip mat,
an adjustable cradle to hold your mobile phone in place and
an LED indicator light.
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.
CAUTION!
The key fob should not be placed on the charging pad or
within 15 cm (150 mm) of it. Doing so can cause excessive
heat buildup and damage to the fob. Placing the fob in
close proximity of the charging pad blocks the fob from
being detected by the vehicle and prevents the vehicle
from starting.

NOTE:
• The charging system is independent from load reduction.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 “Getting To Know Your Instru -
ment Panel” for further information.

The electrical loads that may be switched off (if equipped), and
vehicle functions which can be affected by load reduction:

• Heated Seats/Vented Seats/Heated Wheel
• 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 stop -
ping).
• 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, +12V
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 exterior).
•Check what may be plugged in to power outlets +12V,115V AC, USB ports.
•Check HVAC settings (blower, temperature).
•Check the audio settings (volume).
After a trip:
• Check if any aftermarket equipment was installed (addi -
tional 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 the evaluation
of the vehicle and driving pattern did not help to identify
the cause.WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the instru-
ment panel together with a dedicated message and/or
acoustic signal when applicable. These indications are indic -
ative and precautionary and as such must not be considered
as exhaustive. 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
— Seat Belt Reminder Warning Light
This warning light indicates when the driver or passenger
seat belt is unbuckled. When the ignition is first placed in the
ON/RUN or ACC/ON/RUN position and if the driver’s
seat belt is unbuckled, a chime will sound and the light will
turn on. When driving, if the driver or front passenger seat
belt remains unbuckled, the Seat Belt Reminder Light will
flash or remain on continuously and a chime will sound.
Refer to “Occupant Restraint Systems” in “Safety” for
further information.

— 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.
— 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 spec
-
ified 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.
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.
