Chrysler 300/300 Touring/300C, Dodge Magnum. Manual — part 511

AUTOMATIC HEADLAMP SYSTEM

Automatic headlamps are controlled by the Cab Compartment Node (CCN). With the headlamp switch in the AUTO
position, the CCN will control the headlamp, parking, side marker, tail and instrumentation lamps based on ambient
light levels. Ambient light levels are monitored by the CCN using the ambient light signal present. Ambient light
readings are averaged to limit cycling the lamps ON and OFF when passing through areas with varying light levels.
The automatic headlamps will only function when the engine is running with the RPM greater than 300. When the
headlamp switch is in the AUTO position (Automatic mode), the Headlamp Time Delay system will function when the
ignition switch is placed in any position other than run/start.

HEADLAMP TIME DELAY SYSTEM

The headlamp time delay system is activated by turning the headlamps ON (high or low beam) while the engine is
running, turning the ignition switch OFF, and then turning the headlamp switch OFF. The Cab Compartment Node
(CCN) will allow the headlamps to remain ON for 90 seconds (configurable) before they automatically turn off (If the
key is in the ignition during the headlamp time delay mode, then both the headlamps and park lamps (including
panel dimming) will be ON). Refer to the Owner’s Manual for more information.

If the headlamp switch is in the Auto Headlamp Position, the headlamps are ON due to the night signal from the
ambient light sensor and the ignition switch is in any position other than run/start, the CCN shall enter a 90 second
(configurable) Auto Headlamps time delay mode. If the key is in the ignition during the headlamp time delay mode,
then both the headlamps and park lamps (including panel dimming) will be ON. If the key is not in the ignition, then
only the headlamps will be ON. The CCN will allow the headlamps to remain ON for 90 seconds before they auto-
matically turn OFF. Refer to the Owner’s Manual for more information.

WARNING

Eye protection should be used when servicing glass components. Personal injury or death could result.

This vehicle contains mercury added devices added by the manufacturer: High Intensity Discharge (HID)
headlamps. Remove devices before vehicle disposal. Upon removal of devices, please reuse, recycle, or
dispose of as hazardous waste.

Do not back probe any connectors or pierce any wiring to the HID headlamp system. High voltage (a/c volt-
age) is used in this system and component and personal injury or death could result (Refer to 8 - ELEC-
TRICAL/LAMPS/LIGHTING - EXTERIOR/HEADLAMP - DIAGNOSIS AND TESTING - HID HEADLAMPS).

Do not power up the headlamp assembly with the headlamp access cover off. A high voltage a/c (alternating
current) shock may occur causing personal injury or death.

On vehicles equipped with airbags, disable the airbag system before attempting any steering wheel, steer-
ing column, or instrument panel component diagnosis or service. Disconnect and isolate the battery nega-
tive cable, then wait two minutes for the airbag system capacitor to discharge before performing further
diagnosis or service. Failure to take the proper precautions could result in accidental airbag deployment
and possible personal injury or death.

Do not touch the glass of halogen bulbs with fingers or other possibly oily surface, reduced bulb life will
result. Do not use bulbs other than those indicated in the bulb application table. Damage to lamp and/or
daytime running lamp module can result. Do not use fuses, circuit breakers or relays having greater amper-
age value than indicated on the fuse panel or in the owners manual.

Do not use bulbs other than those listed in the bulb application table. Damage to lamp can result. Do not
touch bulbs with fingers or other oily surfaces. Bulb life will be reduced.

STANDARD PROCEDURE

FRONT LAMP AIMING

VEHICLE PREPARATION FOR LAMP ALIGNMENT

1. Check for and correct any burnt out bulbs.

2. Repair or replace any faulty, worn or damaged body or suspension components that could hinder proper lamp

alignment.

3. Verify proper tire inflation pressures.

4. Remove any accumulations of mud, snow or ice from the vehicle underbody and clean the front lamp lenses.

5. Verify that there is no load in the vehicle (cargo or passengers), except for the driver.

6. The fuel tank should be Full. Add 2.94 kilograms (6.5 pounds) of weight over the fuel tank for each estimated

gallon of missing fuel.

7. Verify correct vehicle suspension height.

LAMP ALIGNMENT SCREEN PREPARATION

The procedure that follows will prepare a suitable front lamp alignment screen.

1. Tape a line on a level floor 7.62 meters (25 feet) away from and parallel to the flat wall that will be used as the

lamp alignment screen. The level floor will be used as the horizontal zero reference.

2. An adjacent wall or floor member that is perpendicular to the alignment screen can be used as the vertical zero

reference. If there is no adjacent wall or floor member that is perpendicular to the screen, tape a second line on
the floor perpendicular to both the alignment screen and the first line, and outboard of either side of where the
vehicle will be positioned. This will be used as the vertical zero reference.

3. Position the vehicle so that the side of the vehicle is parallel to the vertical zero reference, and so that the front

of the lamp lenses are in the vertical plane of the parallel line taped on the floor 7.62 meters (25 feet) away from
the screen.

4. Rock the vehicle side-to-side three times to allow the suspension to stabilize.

5. Jounce the front suspension three times by pushing downward on the front bumper and releasing.

6. Measure the distance between the optical center of one of the lamps being aimed (head or fog) and the floor

(horizontal zero reference). Transfer this measurement to the alignment screen with a piece of tape placed hor-
izontally to the floor. This line will be used as the lamp horizontal reference.

7. Measure the distance between the vertical zero reference and the optical center of the nearest lamp being aimed

(head or fog). Transfer this measurement to the alignment screen with a piece of tape placed vertically across
the appropriate (head or fog) lamp horizontal reference. This is the centerline reference for the first lamp.

8. Measure the distance on center between the first and the second lamp being aimed. Transfer this measurement

to the alignment screen with a second piece of tape placed vertically across the appropriate (head or fog) lamp
horizontal reference. This is the centerline reference for the second lamp.

HEADLAMP ALIGNMENT

There are three different kinds of headlamp aiming procedures:

•

Visual Aim Optical Left (VOL) - 300C with halogen and 300C w/HID.

•

Visual Aim Optical Right (VOR) - 300/300 Touring and Dodge Magnum.

•

Export - 300C w/HID - Export vehicles.

The VOL or VOR is embossed on the lower front of each headlamp unit.

VOL HEADLAMP AIMING

With the horizontal centerline of the headlamp (2) transferred on the wall, measure down 53 mm (2.1 in). This line
(1) will be the vertical aiming mark. Using the left side of the headlamp vertical centerline (3), adjust the headlamp
unit so the residual light from the headlamp, not the hot spot, is even with the line (1) that was marked previously
53 mm (2.1 in) below the horizontal centerline (2). The ideal alignment should be (5). The right headlamp aiming will
be the same, but using the area left of right headlamp vertical centerline (not shown).

1. Turn the headlamps On and select the Low beams.

2. Rotate the headlamp vertical adjustment screw (and horizontal on export) on each lamp to adjust the beam

height as required.

VOR HEADLAMP AIMING

With the horizontal centerline of the headlamp (1) transferred on the wall, this line (1) will be the vertical aiming
mark. Using the right side of the headlamp vertical centerline (2 for the left and 4 for the right), adjust the headlamp
unit so the residual light from the headlamp is even with the horizontal centerline (1). The ideal alignment should be
(5).

1. Turn the headlamps On and select the Low beams.

2. Rotate the headlamp vertical adjustment screw (and horizontal on export) on each lamp to adjust the beam

height as required.

EXPORT HEADLAMP AIMING

With the horizontal centerline of the headlamp (1) transferred on the wall, measure down 76 mm (3 in). This line (6)
will be the vertical aiming mark. Using the intersecting point (5) of the horizontal centerline (6) and the vertical cen-
terline (2) for the left headlamp, adjust the headlamp unit horizontally and vertically so (5) is the intersecting point
at lines (6 and 2). For the right headlamp unit, cover up the left headlamp and follow the same procedure but
intersecting at (6 and 4).

1. Turn the headlamps On and select the Low beams.

2. Rotate the headlamp vertical adjustment screw (and horizontal on export) on each lamp to adjust the beam

height as required.

FOG LAMP ALIGNMENT

A properly aimed front fog lamp will project a pattern on the alignment screen 100 millimeters (4 inches) below the
fog lamp centerline and straight ahead of the lamp.

1. Turn the fog lamps On.

2. Rotate the fog lamp vertical adjustment screw (2)

on each lamp to adjust the beam height as
required.
