NOTE:
•The Automatic High Beam Headlamp Control can be
turned on or off by selecting “ON” under “Auto High
Beam” within your Uconnect settings, as well as turning
the headlight switch to the AUTO position. Refer to
“Uconnect Settings” in “Multimedia” for further infor-
mation.
• 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 obstructions 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.

1. The Automatic High Beams are enabled through the Uconnect system. Refer to “Uconnect Settings” in “Mul-
timedia” for further information.
2. Turn the headlight switch to the AUTO headlight posi- tion. 3. Push the multifunction lever away from you (toward
front of vehicle) to engage the high beam mode.
NOTE: This system will not activate until the vehicle is at

provides a greater gear reduction ratio to provide increased
torque at the wheels.

“Starting And Operating” for further information on four-
wheel drive operation and proper use.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating prop-
erly, your vehicle will provide excellent performance and
fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see
your authorized dealer for service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
• If the MIL is flashing while the vehicle is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
