Daytime Running Lights (DRL) — If Equipped
The headlights on your vehicle will illuminate when the
engine is started and the transmission is in any gear except
PARK. This provides a constant "lights on" condition until
the ignition is turned OFF. The lights illuminate at less than
half of normal intensity. If the parking brake is applied, the
Daytime Running Lights (DRL) 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 acti-
vation. Once the turn signal is no longer active, the DRL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

switch the headlights to high beam. Pulling the multifunc -
tion 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. 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 informa -
tion.
• 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.

GETTING TO KNOW YOUR VEHICLE 69
If the windshield or Automatic High Beam Headlamp
Control mirror is replaced, the mirror must be re-aimed to

Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration of
coolant is used. Use of the Air Recirculation mode during
Winter months is not recommended, because it may cause
window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service (i.e.,
vacation) for two weeks or more, run the air conditioning
system at idle for about five minutes, in fresh air with the
blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor
damage when the system is started again. Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select Defrost
or Mix mode and increase the front blower speed. Do not use
the Recirculation mode without A/C for long periods, as
fogging may occur.
CAUTION!
Failure to follow these cautions can cause damage to the
heating elements:
• Use care when washing the inside of the rear window. Do not use abrasive window cleaners on the interior
surface of the window. Use a soft cloth and a mild
washing solution, wiping parallel to the heating
elements. Labels can be peeled off after soaking with
warm water.
• Do not use scrapers, sharp instruments, or abrasive window cleaners on the interior surface of the window.
• Keep all objects a safe distance from the window.
