Daytime Running Lights (DRLs)
The headlights on your vehicle will illuminate
when the engine is started and the transmis -
sion is in any gear except PARK. This provides a
constant "lights on" condition until the ignition is
placed in the OFF position. The lights illuminate
at less than half of normal intensity. If the
parking brake is applied, the Daytime Running
Lights (DRLs) will turn off. Also, if a turn signal is
activated, the DRL lamp on the same side of the
vehicle may turn off for the duration of the turn
signal activation. Once the turn signal is no
longer active, the DRL lamp will illuminate.
NOTE:
If allowed by law in the country in which the
vehicle was purchased, the Daytime Running
Lights can be turned on and off using the
Uconnect System, refer to “Uconnect Settings”
in “Multimedia” for further information.
High/Low Beam Switch
Push the multifunction lever toward the instru-
ment panel to switch the headlights to high
beam. Pulling the multifunction lever back
toward the steering wheel will turn the low
beams back on, or shut the high beams off.
Automatic High Beam Headlamp Control —
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 digital camera mounted on the
inside rearview mirror or forward facing camera.
This camera detects vehicle specific light and
automatically switches 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, as well as turning the
headlight switch to the AUTO position. Refer
to “Uconnect Settings” in “Multimedia” for
further information.
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 improp -
erly.
To opt out of the Advanced Auto High Beam
Sensitivity Control (default) and enter
Reduced High Beam Sensitivity Control (not
recommended), on vehicles equipped with
mirror controlled automatic high beams and
without the forward facing camera, toggle the
high beam lever six full on/off cycles within
10 seconds of placing the ignition in the ON
position. The system will return to the default
setting when the ignition is OFF.
If the windshield or Automatic High Beam Head -
lamp Control mirror is replaced, the mirror must
be re-aimed to ensure proper performance. See
a local authorized dealer.
To Activate

1. The Automatic High Beams are enabled through the Uconnect system. Refer to
“Uconnect Settings” in “Multimedia” for
further information.

2. Turn the headlight switch to the AUTO head -
light position.
3. Push the multifunction lever away from you (toward front of vehicle) to engage the high

Canadian/Gate Operator Programming
For programming transmitters in Canada/
United States that require the transmitter
signals to “time-out” after several seconds of
transmission.
Canadian radio frequency laws require trans -
mitter signals to time-out (or quit) after several
seconds of transmission – which may not be
long enough for HomeLink® to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators are
designed to time-out in the same manner. It may be helpful to unplug the device during the
cycling process to prevent possible overheating
of the garage door or gate motor.

1. Place the ignition in the ON/RUN position.

2. Place the hand-held transmitter 1 to
3 inches (3 to 8 cm) away from the Home-
Link® button you wish to program while
keeping the HomeLink® indicator light in
view.
3. Continue to press and hold the HomeLink® button, while you press and release
(“cycle”) your hand-held transmitter every
two seconds until HomeLink® has success-
fully accepted the frequency signal. The
indicator light will flash slowly and then
rapidly when fully trained.
4. Watch for the HomeLink® indicator to change flash rates. When it changes, it is
programmed. It may take up to 30 seconds
or longer in rare cases. The garage door
may open and close while you are program -
ming. 5. Press and hold the programmed Home
-
Link® button and observe the indicator
light.
NOTE:
If the indicator light stays on constantly,
programming is complete and the garage
door/device should activate when the
HomeLink® button is pressed.
To program the two remaining HomeLink®
buttons, repeat each step for each
remaining button. DO NOT erase the chan -
nels.
If you unplugged the garage door opener/
device for programming, plug it back in at this
time.

6. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the ignition is in the ON/
RUN position.
 The fuel pump symbol points
to the side of the vehicle where
the fuel door is located.
Refer to “Refueling The Vehicle — Gas
Engine” in “Starting And Operating” for
further information. 7. Temperature Gauge
The gauge pointer shows engine coolant
temperature. The pointer positioned
within the normal range indicates that
the engine cooling system is operating
satisfactorily.
The gauge pointer will likely indicate a higher temperature when driving in hot
weather, up mountain grades, or when
towing a trailer. It should not be allowed
to exceed the upper limits of the normal
operating range.
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by steam
or boiling coolant. You may want to call an
authorized dealer for service if your vehicle
overheats. If you decide to look under the
hood yourself, see “Servicing And
Maintenance.” Follow the warnings under the
Cooling System Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the
temperature gauge reads “H,” pull over and
stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on the “H,” turn the engine off
immediately and call an authorized dealer for
service.
