Courtesy of CHRYSLER LLC

The exterior lighting system for this vehicle includes the following exterior lamp units:



Center High Mounted Stop Lamp (2) - A standard equipment Center High Mounted Stop Lamp
(CHMSL) is centered on the upper liftgate header above the liftgate glass opening at the rear of the
vehicle.



Front Fog Lamps (6) - Optional equipment front fog lamp units are mounted near each outboard end of
the front fascia, below the front headlamp units.



Front Lamp Units (1) - A standard equipment front lamp unit is located at each outboard end of the
grille assembly in the front end module.



License Plate Lamps (3) - Two standard equipment rear license plate lamp units are integral to the light
bar assembly, just above the license plate tub formation in the outer liftgate panel.



Rear Lamp Units (4) - A standard equipment rear lamp unit is mounted to the rear of each quarter panel
on either side of the liftgate opening.



Repeater Lamps (5) - A repeater lamp is mounted to each front fender just behind the front wheel
opening on vehicles manufactured for certain markets where they are required.

These exterior lighting lamp units and their controls are combined to provide the following exterior lighting
features:



Backup Lamps - The backup (or reverse) lamps include a clear bulb, reflector and clear lens that are
integral to each rear lamp unit.



Brake Lamps - The brake (or stop) lamps include a clear bulb, reflector and red lens that are integral to
each rear lamp unit, and the red lens and multiple Light-Emitting Diode (LED) units of the CHMSL.



Daytime Running Lamps - Vehicles manufactured for sale in Canada illuminate the high beam
headlamp bulb in each front lamp unit at a reduced intensity to serve as the Daytime Running Lamps
(DRL). United States fleet vehicles illuminate the low beam headlamp bulb in each front lamp unit to
serve as DRL.



Exterior Lamp Fail-Safe Operation - The Electro Mechanical Instrument Cluster (EMIC) (also known
as the Cab Compartment Node/CCN) and the Totally Integrated Power Module (TIPM) provide a fail-
safe feature which will automatically turn ON the low beam headlamps and all park lamps when the
ignition switch is in the ON position and there is no detected input from the Steering Control Module
(SCM), or when there is no communication over the Local Interface Network (LIN) or Controller Area
Network (CAN) data buses.



Exterior Lamp Load Shedding - The TIPM provides a battery saver feature which will automatically
turn OFF all exterior lamps (except park lamps in certain markets) that remain ON with the ignition
switch in the LOCK position after a timed interval of about eight minutes.



Front Fog Lamps - The optional equipment front fog lamps include the clear bulb, reflector and clear
lens of each adjustable front fog lamp unit.



Hazard Warning Lamps - The hazard warning lamps include the bulbs, reflectors and lenses of each
lamp in the right and left, front and rear turn signal circuits.



Headlamp Delay - The standard equipment low or high beam headlamps remain illuminated for a
customer-programmable delay period of 0 (disabled), 30, 60 or 90 seconds when the headlamps are
turned OFF after the ignition switch has been turned to the OFF position.



Headlamps - The headlamps include a single, dual filament halogen bulb, an adjustable reflector and a
clear lens integral to each front lamp unit.



Headlamp Leveling - Headlamp leveling is available only in certain markets where it is required
equipment. A headlamp leveling actuator motor on each headlamp unit and a headlamp leveling switch
integral to the switch pod in the instrument panel allow the headlamp beam pattern to be adjusted by the
vehicle operator from the interior of the vehicle to compensate for passenger or cargo loads.



Optical Horn - Also known as flash-to-pass, the beam selection function of the left (lighting) multi-
function switch control stalk has a momentary intermediate position that allows the headlamp high beams
to be flashed momentarily, without changing the headlamp beam selection.



Park Lamps - The front park lamps include the amber bulbs, the reflectors and the clear lenses of the
front lamp units as well as either the clear bulbs and the amber lenses of the front side marker lamps or
the clear position lamp bulb integral to each headlamp. The rear park lamps include a clear bulb, a
reflector and a red lens integral to each rear lamp unit as well as the clear bulb and lens of the license
plate lamp units.



Rear Fog Lamps - Rear fog lamps are available only in certain markets where they are required
equipment. The rear fog lamps include a clear bulb, a reflector and a red lens that are integral to each rear
lamp unit.



Turn Signal Lamps - The front turn signal lamps include an amber bulb, a reflector, and a clear lens that
are integral to each front lamp unit and the front side marker lamps. In certain markets where required,
the repeater lamps on each front fender replace the front side marker lamps in the front turn signal
