Collision Warning (FCW) Sensor Protective
Cover — If Equipped
Your vehicle may be equipped with a protective cover that
is to be used whenever the windshield is folded down in
order to protect the Adaptive Cruise Control (ACC)/
Forward Collision Warning (FCW) sensor. To install the
cover, follow these instructions:

1. Secure the top part of the cover so that it hinges to the header.

2. Swing the cover down and push on it so that it covers the opening.
3. Check to make sure the cover is secured properly.
NOTE:Be sure to remove the cover before returning the wind -
shield to the normal position. Store the cover in the cargo
area.
Cleaning Instructions
During windshield down applications, dust/dirt can
accumulate in the cover and block the camera lens. Use a
microfiber cloth to clean the camera lens, module, and
inside cover, being careful not to damage or scratch the
module.
RAISING THE WINDSHIELD

1. Release the strap that secured the windshield in the lowered position.

2. Raise the windshield.
3. Using the provided #40 Torx head driver, reinstall the four Torx screws located along the interior of the
windshield. Secure them until they are snug, being

Electronic Stability Control (ESC) OFF
Warning Light — If Equipped
This warning light indicates the ESC is off.
Each time the ignition is turned to ON/RUN or
ACC/ON/RUN, the ESC system will be on, even
if it was turned off previously.
Loose Fuel Filler Cap Warning Light —
If Equipped
This warning light will illuminate when the fuel
filler cap is loose. Properly close the filler cap to
disengage the light. If the light does not turn
off, please see an authorized dealer.
Low Fuel Warning Light
When the fuel level reaches approximately 2.0
gal (7.5 L), this light will turn on and a chime will
sound. The light will remain on until fuel is
added.
Low Washer Fluid Warning Light —
If Equipped
This warning light will illuminate when the
windshield washer fluid is low Úpage 314.
Engine Check/Malfunction Indicator
Warning Light (MIL)
The MIL is a part of an Onboard Diagnostic
System called OBD II that monitors engine and
automatic transmission control systems. This
warning light will illuminate when the ignition is in the ON/RUN position before engine start. If the bulb
does not come on when turning the ignition switch from
OFF to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap,
poor quality fuel, etc., may illuminate the light after engine
start. The vehicle should be serviced if the light stays on
through several typical driving styles. In most situations,
the vehicle will drive normally and will not require towing.
When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced by an authorized dealer as soon as
possible if this occurs.
AdBlue® (UREA) Injection System Failure
Warning Light — If Equipped
This warning light will illuminate along with a
dedicated message on the display (if equipped)
if an unknown fluid not conforming with
acceptable characteristics is inserted, or if an
average consumption of AdBlue® (UREA) over 50% is
detected. Contact an authorized dealer as soon as
possible.
If the problem is not solved, a specific message will appear
on the instrument cluster display whenever a certain
threshold is reached until it will no longer be possible to
start the engine.
When about 125 miles (200 km) are remaining before the
AdBlue® (UREA) tank is empty, a continuous dedicated
message will appear on the instrument panel,
accompanied by a chime.
Service 4WD Warning Light — If Equipped
This warning light will illuminate to signal a fault
with the 4WD system. If the light stays on or
comes on during driving, it means that the 4WD
system is not functioning properly and that
service is required. We recommend you drive to the
nearest service center and have the vehicle serviced
immediately.
Service Adaptive Cruise Control Warning
Light — If Equipped
This light will turn on when a ACC is not
operating and needs service Úpage 152.
WARNING!
A malfunctioning catalytic converter, as previously
referenced, can reach higher temperatures than in
normal operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such as
dry plants, wood, cardboard, etc. This could result in
death or serious injury to the driver, occupants or
others.
CAUTION!
Prolonged driving with the Malfunction Indicator Light
(MIL) on could cause damage to the vehicle control
system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
