Land Rover Defender: Exterior Lighting - Operation

TAIL LAMP OPERATION - REST OF WORLD

1. Rear position lamp ON
2. Stop lamp ON
3. Turn signal indicator ON
4. Reverse lamp ON

TAIL LAMP OPERATION - NORTH AMERICAN SPECIFICATION

1. Tail lamp ON
2. Stop lamp ON
3. Turn signal indicator ON
4. Back Up Lamp ON

EMERGENCY STOP SIGNAL - ROW ONLY

The Emergency Stop Signal is enabled only when the vehicle speed is above 50 km/h (31 mph). The Emergency Stop Signal is enabled and disabled automatically .

The Emergency Stop Signal operates independently of other lamps but does not override any turn signal indicator or hazard warning lamp function.

In the event of Emergency Stop Signal activation, the hazard warning lights are enabled. The brake lights start flashing instead of being constantly on.

The hazard warnings are disabled when driving off again or by pressing the hazard warning button.

CORNERING LAMP - IF EQUIPPED

The cornering lamp (If front fog lamps are equipped) is controlled by:

• Left steering column switch
• Steering Angle Sensor Control Module (SASM).

If either the left or right turn signal indicators is selected, the vehicle speed is less than 40 km/h (24 mph), the cornering lamps illuminate.

When a turn angle signal is generated from the SASM and the vehicle speed is less than 40 km/h (24 mph), the cornering lamps illuminate (Matrix LEDs headlamp only).

FRONT FOG LAMP - IF EQUIPPED

NOTE: The front fog lamps remain ON when the high beam 'flash' function is operated.

Each fog lamp uses LEDs light source which is controlled by the BCM/ GWM.

The fog lamp switch can be rotated to enable the front fog lamps when the following conditions occur:

• Power Mode 6 (ignition ON) or above.
• The left steering column switch is in the side lamp or headlamp position.
• The left steering column switch is in the 'AUTO' and rain/light sensor is requesting low beam.

FRONT FOG LAMP FUNCTIONALITY - NAS ONLY

The front fog lamps operate as described previously but there are following differences which cover local laws governing lamp usage.

If the low beam and the front fog lamps are ON and the high beam is selected, the front fog lamps are deactivated.

REAR END COLLISION ALERT SIGNAL - ROW ONLY

The Rear End Collision Alert Signal operates independently of other lamps and is enabled/disabled automatically.

The Rear End Collision Alert Signal is not enabled when the turn signal indicator, the hazard warning lamp or Emergency Stop Signal is enabled.

MANUAL HEADLAMP LEVELING - IF EQUIPPED

NOTE: RHD vehicle is shown, LHD vehicle is similar.

The LED headlamp has a manual control switch for headlamp leveling. The switch should be used for laden conditions as described:

The positions are defined as follows:

0 - Driver or driver and front passenger.
1 - Driver and all passengers.
2 - Driver and all passengers and luggage to the maximum.
3 - Driver only and luggage to the maximum.

AUTOMATIC HEADLAMP LEVELING - IF EQUIPPED

Vehicles with Premium LEDs or Matrix LEDs headlamps, have air suspension installed and NAS market vehicles have automatic headlamp leveling.

HEADLAMP COURTESY DELAY

1. Lock
2. Headlamp ON/OFF
3. Panic alarm
4. Unlock
5. Tailgate unlatch

The BCM/ GWM controls a headlamp delay function which illuminates the driveway after leaving the vehicle. The BCM / GWM enables the low beam for the required delay period. The headlamps remain illuminated for up to 4 minutes.

Press the smart key headlamp button to switch the lamp OFF.

The timeout period can be changed from the following points:

• OFF
• 30 seconds
• 60 seconds
• 120 seconds
• 240 seconds.

The default value is 30 seconds. This feature can be configured in the 'Vehicle' menu. Activation of the automatic lamp timeout feature also displays a message in the message center.

REMOTE HEADLAMP

The remote headlamp allows the low beam to illuminate for a selectable pre-set period by pressing the headlamp button on the smart key. The headlamps illuminate ON when the first button press, and a further button press switches OFF the headlamps.

The remote headlamp operation feature uses the same timeout period as set by the headlamp delay timeout feature.

However when the timeout period has been set to '0', then remote headlamp operation uses the default value of 30 seconds.

CRASH INDICATIONS

When the vehicle crash sensor is triggered, the hazard warning lights operate automatically until the crash signal is reset or they are manually switched off.

TIRE PRESSURE ASSIST - NAS ONLY

With the Tire Pressure Assist enabled from the "Vehicle" and "Tire Information" menus, the turn signal indicators flash to identify tire inflation status.

TRAFFIC JAM PILOT

Traffic jam pilot allows the vehicle to follow the preceding vehicles along a highway. In order to do so it needs to have a good vision of the road ahead. Ideally the lighting system needs to be set to automatic (rain/light sensor in daytime or headlamps at night-time). However, there are number of use cases where the driver may change the lighting system away from ideal auto state (for example, fog in daytime).

Traffic jam pilot is enable when:

• The lighting system is operating in automatic mode.
• The low beams are manually enabled and/or the front fog lamps are enabled.

Traffic jam pilot requests confirmation from the driver. The Traffic jam pilot is disabled when any manual control of the lighting system falls outside of these parameters.

Temporary activation of high beam (flash) is permitted but Auto High Beam can not operate high beam when traffic jam pilot is enabled.

DRIVER FATIGUE ALERT

This function aims to bring the vehicle to a stop, where it is safe to do so when the driver becomes unresponsive.

Driver fatigue alert is triggered when the system confirms the driver is unresponsive. The feature triggers the activation of the hazard warning lamps, decelerates the vehicle in-lane and secures it, when it has been brought to rest.

The signal is activated on receipt of the hazard warning lamps activation signal from Blindspot Monitoring Control Module (SODL)/ SODR control module.

The signal is canceled when the hazard warning lamps switch is pressed or SODL/ SODR stops sending the hazard warning lamps activation signal.

AUTOMATED PARKING

The Automated Parking feature identifies parking spaces and automatically parks the vehicle into a suitable space. To make sure the visibility of the moving vehicle, the showing of exterior lights may be requested. In some markets, turn signal indicators are enabled as required for a left/right turn. This feature requests lights to go to auto when being activated.

A request for auto lights operation is made at the start of automated parking mode. When any exterior lights are already ON, this command is ignored. When no exterior lights are active then the appropriate lights for automode in the prevailing conditions are enabled.

The turn signal indicator is switched OFF after completion of turn maneuver or cancellation of automated parking in appropriate markets.

REMOTE PARKING

The feature requests lights to go to auto on activation. The turn signal indicator is switched OFF after completion of the turn maneuver or cancellation of remote parking in appropriate markets.

REMOTE CONTROL DRIVE

The feature enables moving the vehicle controlled by a mobile device at less than 2 km/h (1.2 mph). When this feature is operational the vehicle hazard warning lamps operate in appropriate markets.

ADAPTIVE DRIVING BEAM

Adaptive Driving Beam is equipped on Matrix LEDs headlamps (except NAS), to create shadowing in order to adapt the light distribution to the road conditions ahead.

The Adaptive Driving Beam system operates when the following conditions are met:

• The vehicle speed is above 40 km/h (24 mph).
• No street lights are detected by the forward facing camera.
• Ambient light illuminance less than 6 lux.
• No unfavorable weather conditions (fog, rain or snow) detected by the camera.
• The vehicle is not in REVERSE.

The system becomes active by shadowing objects detected when:

• Oncoming vehicle is at a distance greater than 400 meters or less.
• Preceding vehicle is at a distance greater than 100 meters or less.
• Bicycle is at an oncoming distance greater than 75 meters.
• Reflective object is recognized:
  • Reflective objects where the reflection could cause a glaring concern for the driver is detected.

NOTE: When any of the above conditions are not met, the Adaptive Driving Beam does not operate.

The system becomes inoperative when:

• The vehicle speed is below 24 km/h (14 mph).
• The street lights are detected by the forward facing camera.
• The ambient light illuminance is greater than 1000 lux.
• The unfavorable weather conditions (fog, rain, or snow) detected by the camera.
• The vehicle in REVERSE.

The following instructions for enabling or disabling Adaptive Driving Beam function:

1. Pull and release the left steering column switch to manually override to low beam from Adaptive Driving Beam.

   The IPC warning lamp illuminates.

2. Push and release the left steering column switch to return to Adaptive Driving Beam. The IPC warning lamp illuminates.
3. Repeated pushing of the left steering column switch toggles the operation of the high beam between automatic and manual.
4. Rotate the left steering column switch to the low beam to switch the Adaptive Driving Beam system OFF.

AUTO HIGH BEAM

The high beam is disabled in the case of preceding or oncoming vehicles or in urban areas. This leads to an optimal usage of the headlamps while driving at night:

• Improving visibility to the driver.
• Relieving the driver of the task of manually controlling the high beams.

The functionality of the Auto High Beam system is distributed between the IPMA and the BCM/ GWM.

The driver may at any time manually override the Auto High Beam to operate the beams in a manual mode by using the left steering column switch.

When the system is active, the feature uses visual data from a forward facing camera to detect:

• When there are preceding or oncoming vehicles.
• If the vehicle is in an urban area.

The Auto High Beam system is enabled or disabled by:

• IPC menu
• FCDIM menu
• Occupant Monitoring Module (OMM).

The following instructions for enabling or disabling Auto High Beam system:

1. Pull and release the left steering column switch to manually override to low beam from Auto High Beam. The IPC warning lamp illuminates.
2. Push and release the left steering column switch to return to Auto High Beam. The IPC warning lamp illuminates.
3. Repeated pushing of the left steering column switch toggles the operation of the high beam between automatic and manual.
4. Rotate the left steering column switch to the low beam to switch the Auto High Beam system OFF.

ADAPTIVE FRONT LIGHTING SYSTEM

1. Motorway mode
2. Country mode and adverse weather mode
3. City mode

The AFS is active when AUTO lights is selected and the ambient light level is below a predetermined level. The AFS is deactivated when high beam is manually selected or AUTO lights are deselected.

NOTE: If an urban environment is detected, country mode or city mode operates.

While operating as an AFS, the dipped beams are automatically adjusted to suit the vehicle speed and weather conditions:

• Country mode operates unless any of the conditions in City mode, Motorway mode and Adverse weather mode are met. Country light operates when the vehicle is stopped or High Beam is operating.
• City mode: A wider headlamp beam that operates at vehicle speeds up to 48 km/h (30 mph) when an urban environment is detected.
• Motorway mode: A raised headlamp beam that operates at vehicle speeds above 110 km/h (68 mph).
• Adverse weather mode: Operates when the windshield wipers are active for more than 2 minutes and the vehicle's speed is below 64 km/h (40 mph).

DIAGNOSTICS

The BCM/ GWM records any Diagnostic Trouble Code (DTC)s and related data. Read the DTCs and related data with the Jaguar Land Rover (JLR) approved diagnostic equipment.

The JLR approved diagnostic equipment enables certain components to be activated and also live data to be read.
