BMW 7 Series: Hazard Warning Lights

The hazard warning lights are switched on by pressing the hazard warning switch. As a result, all direction indicator lights are activated simultaneously and the indicator in the hazard warning switch flashes in time.

The steering column switch has priority if it is moved in left or right direction while the hazard warning lights are active. The hazard warning function resumes after "Terminal 15 OFF" or cancelling the direction indicator.

The hazard warning lights have priority when the direction indicator lights for turning left or right are switched on and the hazard warning light switch is pressed.

COMPONENTS DESCRIPTION CHART

1. Hazard warning switch
2. Central-locking button

NOTE: At Terminal 30/Terminal 30B ON the hazard-warning lights are switched on with reduced consumption. This means the hazard-warning lights are on for a shorter time and off for a longer time.

Hazard warning lights in connection with alarm triggered by the anti-theft alarm system

The footwell module receives the request for the hazard warning lights via the K-CAN2. The signal is sent by the ultrasonic interior movement detector.

The alarm time for the hazard warning lights is 6 minutes provided the anti-theft alarm system is not switched off. The hazard warning light switch is blanked out during the alarm and therefore does not flash together with the lights.

NOTE: The ultrasonic interior movement detector is completely integrated in the roof functions center, both in terms of hardware and software.

Visual and Audible Indicators

The instrument cluster provides visual and audible indication of the turn signals. The footwell module informs the instrument cluster via the K-CAN2 to activate the acoustic generator and the indicator lights together with the direction indicator lights.

The visual/audible indicator in the instrument cluster switches off if the vehicle is locked with the central locking while the hazard warning light function is active.

Tail Light/License Plate Light

In the same way as the side lights, the tail light can be switched on from Terminal 30F ON together with the license plate light by using the light switch (position 1).

Rear Light Cluster

The rear light cluster of the F01/F02 is based on a split design. One part is integrated in the body and the other in the luggage compartment lid. The two parts form the complete rear light cluster.

The rear light cluster in the body section is fitted with LEDs for the following lighting functions.

• Tail lights
• Brake light
• Direction indicator lights
• Side marker light, integrated in the tail light.

Three lighting functions are integrated in the rear light cluster. They are:

• Reversing lights 16 W
• Brake light (US version "Brake Force Display" - BFD)
• Tail lights based on LEDs.

At Terminal 30 the consumption of the tail lights is reduced by only switching on the tail light in the rear side panel.

License Plate Light

The license plate light is designed based on LEDs. The LEDs are integrated in the strip handle on the luggage compartment lid. Three LEDs are used for each license plate light.

Brake Light

As from "Terminal R ON", the brake lights can be switched on by activating the brake light switch.

The Car Access System powers the brake light switch with 5 V voltage. The footwell module evaluates the status of the brake pedal switch and actuates the brake light. The brake light switch provides two levels.

The signal of the brake pedal switch is also used for the beam throw adjustment (LWR).

NOTE: The brake light can also be activated by a braking assistant function such as ACC.

Adaptive Brake Light - US

The current adaptive brake light remains in the national-market version US. Braking is indicated by an increase in size and luminous intensity. It is not permissible for the red surfaces of the brake light to flash. The adaptive brake light is part of the standard equipment.

The following conditions must be met for operation of the adaptive brake light:

• Driving speed > 5 kph (3 mph)
• Brake deceleration above 5 m/s2 or
• Control intervention by the antilock braking system.

Reversing Light

The reversing light can be switched on as from "Terminal 15 ON". The footwell module receives the signal via the K-CAN2. The electronic transmission control unit makes available this signal.

When the vehicle is in trailer towing mode, the reversing light of the trailer is additionally activated via the trailer module.

Parking Lights

The parking lights are switched on with the steering column switch as from "Terminal 30" and detected by the footwell module via the KCAN2.

For the parking light function, the footwell module activates the front side lights and the tail light in the outer chamber of the rear light cluster.

The steering column stalk for the parking lights must be pressed for longer than half a second. This prevents the parking lights being switched on by mistake, e.g. by knocking against the steering column switch while getting out of the car.
