AUTOMATIC HIGH BEAM HEADLAMP
C
ONTROL — IF EQUIPPED
The Automatic High Beam Headlamp Control
system provides increased forward lighting at
night by automating high beam control through
the use of a camera mounted on the inside
rearview mirror or a windshield mounted
camera. These cameras detect vehicle specific
light and automatically switch from high beams
to low beams until the approaching vehicle is
out of view.
NOTE:

The Automatic High Beam Headlamp Control can
be turned on or off by selecting “ON” under “Auto
Dim High Beams” within your Uconnect Settings

Ú
page 228, as well as turning the headlight
switch to the AUTO position.

Broken, muddy, or obstructed headlights and
taillights of vehicles in the field of view will
cause headlights to remain on longer (closer to
the vehicle). Also, dirt, film, and other obstruc -
tions on the windshield or camera lens will
cause the system to function improperly.

If the windshield or Automatic High Beam
Headlamp Control mirror is replaced, the
mirror must be re-aimed to ensure proper
performance. See a local authorized dealer.
To opt out of the Advanced Auto High Beam
Sensitivity Control (default) and enter

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 Úpage 108.
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
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 capa -
bility 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, 115 Volt AC, USB ports) during
certain driving conditions (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 appli -
ances 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 +12 Volts, 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 the evaluation of the vehicle and driving
pattern did not help to identify the cause.
