Ford Galaxy / Ford S-MAX. Manual — part 755

Description

Turn signal lamp

Main beam headlamps

Dipped beam headlamps (gas discharge headlamps)

Adaptive front light

Gas discharge headlamps module

WARNING: High voltages of up to 30 kV are present in the system. Ensure that the

headlamp assembly electrical connector is disconnected if the headlamp assembly is
removed.

High intensity discharge headlamps are optionally available.

A single Xenon gas discharge lamp in the center projector is used for both the dipped beam
and main beam headlamps.

In main beam mode the 15° aperture required for dipped beam operation is pushed out
from the light beam by a positioning motor, as a result of which the full light beam of the
gas discharge lamp becomes available.

An additional reflector with a conventional filament bulb is available for main beam
operation. This bulb is also switched when the headlamp flashers are used.

The headlamp leveling positioning motor cannot be replaced by itself. If necessary, it needs
to be replaced together with the complete headlamp unit.

The gas discharge headlamps can be adapted to different traffic requirements in different
countries (e.g. driving on the left/right) by applying pre-cut adhesive template strips to
specific areas of the headlamps.

Headlamp leveling system

An automatic headlamp leveling system is a legal requirement for vehicles with gas
discharge headlamps.

The automatic headlamp leveling system is a second-generation dynamic system which
provides additional benefits for the driver in terms of improved illumination of the road due
to improved control over the headlamp beam.

In a static system, the vehicle is only considered as a stationary object, whereas a dynamic
system also takes into account the dynamic changes to the inclination of the vehicle owing
to load changes whilst driving.

The system is designed to respond to changes in the inclination of the vehicle caused by the
long-term effects of aerodynamic forces acting on the vehicle (e.g. due to continuous

driving at high speeds).

In order to prevent unnecessary changes in the height of the headlamp beam, the system
filters out surface irregularities and any pitching of the vehicle under braking and
acceleration.

The following components are part of the headlamp leveling system:

Control module
Actuator motors for headlamp leveling
Headlamp leveling sensors on the front and rear axles

Front headlamp leveling sensor

Rear headlamp leveling sensor

The front and rear sensors are Hall sensors, which transmit an analog signal to the control
module.

Accordingly, the system needs to be set up with WDS after any components are replaced or
any other repairs are carried out.

Adaptive front light

On vehicles with projection headlamps with dynamic adaptive front lighting or with gas
discharge headlamps, an additional cornering light system is provided which is located in
the inner part of the headlamp unit.

The cornering lights are switched on depending on the vehicle speed (up to 80 km/h max.)
in conjunction with the steering angle (approx. 30° with the vehicle stationary). As a
requirement for this, either the dipped beam headlamps or the main beam headlamps need
to be switched on.

During cornering only the cornering light on the inside of the bend is switched on to
improve illumination of the bend.

Automatic headlamps

The low beam headlamps and side lamps are switched on automatically if all of the
following conditions are satisfied:

Ignition switch in the "II" or "III" position

Light switch in the "AUTO" position
Detected ambient light conditions below a stored threshold value

The dipped beam headlamps and the side lights are switched on or off by the generic
electronic module (GEM) depending on the input signals of the combined rain sensor/light
sensor.

Combined rain sensor/light sensor

Description

Lens

Front light sensor

Ambient light sensor

The combined rain sensor/light sensor is attached to the windshield, near the interior rear
view mirror.

The ambient light sensor determines the general light intensity.

For this purpose, it detects the light over as wide an angle as possible, without taking the
direction of incidence into account.

The front light sensor determines the light intensity directly in front of the vehicle.

If both the ambient light sensor and the front light sensor detect a sudden reduction in light
intensity at the same time, then an algorithm-based calculation is used to determine the
fact that the vehicle has entered a tunnel.

In this type of case a request to switch on the exterior lights and the display lamps in the
instrument cluster is transmitted to the GEM.
