417-02 : Interior Lighting

Description and operation

Interior Lighting

The interior lighting system consists of the following components:

•

One front interior lamp and two map reading lamps.

•

Soft mood lighting.

•

Front footwell lamps.

•

Two rear interior lamps with integral reading lamps.

•

Front/rear door puddle lamps.

•

Glove compartment lamp.

•

Vanity mirror lamps.

•

Two luggage compartment lamps..

The automatic operation of the interior lights is controlled by the front electronics module
(FEM). Pressing the interior light switch in the overhead console switches the interior lighting
control from automatic to the ON position. When the switch is in the ON position if any of the
doors are open, none of the individual interior lamps can be turned off.

In the AUTOMATIC position, when the interior lights have faded out , each lamp can be
switched on or off by pressing the associated switch. Also in this position, if a door is open
when the vehicle is driven the interior lighting will fade off and then fade back on again when
the vehicle slows down.

With the switch in the AUTOMATIC position the following times apply to the interior lights
fading out assuming lights on.

Soft mood lighting is fitted in the roof console and to the top of the two rear interior lamps.
This lighting scatters subtle illumination onto the floor console and the headlining with the
headlamps on.

The interior lamp is incorporated in the roof console. <<501-12>>

417-04 : Daytime Running Lamps

Description and operation

Daytime Running Lamps (DRL)

DRL use the full intensity low beam headlamps which are permanently illuminated when the vehicle

is being driven. DRL are used in a number of markets and there are two systems to cover these

markets.

DRL CANADIAN MARKET

DRL for this market use full intensity low beam headlamps. The side marker lamps and license plate

lamps will be on, but instrument cluster illumination will be off. DRL are active when the following

parameters are met:

•

Parking brake is off on vehicles with manual transmission or PARK is not selected on vehicles
with automatic transmission

•

Ignition switch is in the ignition position (II)

•

The central junction box receives an engine running signal

•

The lighting control switch is in the off or side lamps position. If the switch is in the 'AUTO'
position the DRL will be active when the light sensor is not operating the headlamps using
the auto lamps function.

If the above conditions are met, the low beam headlamps are illuminated by a Pulse Width

Modulated signal (PWM) for the vehicles fitted with halogen headlamps (when the average voltage

exceeds 14V). Vehicles with High Intensity Discharge (HID) headlamps operate the dip beam at

normal supply voltage.

The front park lamps (including front side markers) and low beam lamps are illuminated from the

Front Electronic Module (FEM), the rear park lamps (including the rear side markers and the license

plate lamps) are illuminated by the Rear Electronic Module (REM).

If the lighting control switch is moved to the side lamp or headlamp positions or the auto lamps

feature has activated the headlamps, DRL are deactivated and normal side lamp and headlamp

functionality is operational.

NOTE:

When DRL are active, the headlamp flash function using the left hand steering column

multifunction switch will operate normally. The high beam headlamp function using the left

hand steering column stalk switch will be deactivated.

When the parking brake is applied on manual transmission vehicles or the selector lever is in the

PARK position on automatic transmission vehicles, DRL are turned off. This is to reduce battery

discharge during long periods of engine idling in cold climate conditions. When the parking brake is

released or the selector lever is moved from the PARK position, normal DRL functionality is restored.

DRL DENMARK, HOLLAND, NORWAY, SWEDEN, FINLAND AND POLAND

NOTE:

DRL for Poland is on vehicles from 2008MY.

DRL for these markets use full intensity low beam headlamps. Side lamps and license plate lamps will

be on, but instrument cluster illumination will be off. DRL are active when the following parameters

are met:

•

Ignition switch is in the ignition position (II)

•

The central junction box receives an engine running signal

•

The lighting control switch is in the off position. If the switch is in the 'AUTO' position the DRL
will be active when the light sensor is not operating headlamps using the auto lamps
function.

If the above conditions are met, the low beam headlamps are illuminated by a Pulse Width

Modulated signal (PWM) for the vehicles fitted with halogen headlamps (when the average voltage

exceeds 14V). Vehicles with High Intensity Discharge (HID) headlamps operate the dip beam at

normal supply voltage.

The front park lamps (including front side markers) and low beam lamps are illuminated from the

Front Electronic Module (FEM), the rear park lamps (including the rear side markers and the license

plate lamps) are illuminated by the Rear Electronic Module (REM).

If the lighting control switch is moved to the side lamp or headlamp positions or the auto lamps

feature has activated the headlamps, DRL are deactivated and normal side lamp and headlamp

functionality is operational.

NOTE:

When DRL are active, the headlamp flash function using the left hand steering column

multifunction switch will operate normally. The high beam headlamp function using the left

hand steering column stalk switch will be deactivated.
