activating mechanisms. The webbing sensor activates the locking mechanism if the webbing is subjected to a sharp pull.
The car sensor activates the locking system if the vehicle is subjected to sudden deceleration or severe tilt angle.
All row 1 driver and passenger emergency locking retractor incorporate an electrically activated webbing tension reducer
(comfort device). This device is activated when the vehicle enters ignition mode 6 and insertion of the seatbelt tongue into
the buckle.
All row 2 passengers and NAS front Passenger emergency locking retractors are enhanced with automatic locking retractors.
The automatic locking retractor allows webbing to be extracted to activate a ratchet device. This device allows webbing to
be cinched tight to facilitate child seat fitment. W ith seatbelt webbing tensioned in automatic locking retractor mode the
seatbelt is always locked.
A safety belt warning indicator is installed in the instrument cluster to remind the front seat occupants to fasten their
safety belts. On North American Specification (NAS) vehicles, when the ignition mode is accessory/convenience, the
warning indicator illuminates if the safety belt of an occupied front seat is not fastened. The warning indicator remains
illuminated until the safety belt of each occupied front seat is fastened, or the ignition mode is off. In all markets except
NAS, a belt minder function provides a more intrusive reminder to fasten the front safety belts.
Belt Minder Function
The belt minder function provides warnings to the driver if the appropriate front safety belts are not fastened when driving.
The belt minder function is controlled by the instrument cluster using:
High speed CAN (controller area network) bus messages, from the RCM (restraints control module) , to monitor the
status of the front safety belts.
An input from the occupant detection system to monitor the status of the front passenger seat.
When the ignition is switched to on, the instrument cluster illuminates the safety belt warning indicator until one of the
front safety belts is fastened or the belt minder function is triggered. The belt minder function is triggered when the
ignition switch is in accessory/convenience and the following conditions coexist:
The belt minder function is enabled
The vehicle is not in reverse
Vehicle speed is 8 km/h (5 mph) or more
The driver safety belt or, if the front passenger seat is occupied, the front passenger safety belt, is unfastened.
When the belt minder is triggered, the instrument cluster generates the following warnings for 10 seconds.
Flashes the safety belt warning indicator at 2 Hz
Sounds a repeating chime in sequence with the flashing safety belt warning indicator.
After 10 seconds, the repeating chime is discontinued and the safety belt warning indicator changes from flashing to
continuously illuminated for 20 seconds. W hile the trigger conditions still coexist, the warnings are repeated every 30
seconds until one of the following occurs:
5 minutes has elapsed from when the warnings were first triggered
The safety belt of each occupied front seat is fastened
The ignition mode is position 0
The vehicle speed decreases to 5 km/h (3 mph).
For non NAS vehicles the belt minder function can be enabled and disabled using the driver safety belt switch. The
instrument cluster changes the state of the belt minder function if, within 60 seconds of first entering ignition mode II, the
driver safety belt is fastened and unfastened nine times. Successful completion of the change is indicated by a single
chime and the safety belt warning indicator flashing five times, at 2 Hz. The belt minder function can also be enabled and
disabled using the reccomeneded Land Rover diagnostic tool.
Safety Belt Warning Indicator
SECOND ROW SAFETY BELTS
The retractor of each outboard second row safety belt is attached to the body immediately behind the D pillar. The
webbing runs from the retractor, through an upper mounting on the D pillar, to an anchor point at the front of the related
wheel arch.
The retractor for the center second row safety belt is installed in the top of the seat back. The webbing runs from the
retractor, over the top of the seat, to an anchor point at the base of the seat frame.
The buckles for the second row safety belts are attached to the related seat frame.

Safety Information
• W ARNINGS:
To avoid accidental deployment the back-up power supply must be depleted before beginning any work on the SRS
system or its components. Failure to follow this instruction may result in personal injury
Do not use a multimeter to probe an SRS module. It is possible for the power from the multimeter battery to trigger
the activation of the module. Failure to follow this instruction may result in personal injury
• NOTE: Do not to use a cellular phone or to have a cellular phone in close proximity when working on the SRS system or
components
Power supply depletion
Before beginning any work on the SRS system or related components:
1. Remove the ignition key
1.
2. Disconnect the battery leads, ground first
2.
3. Wait 2 minutes for the power circuit to discharge
3.
There are comprehensive instructions on the correct procedures for SRS system repairs, refer to the relevant section of the
workshop manual
Inspection and Verification
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does
not guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor
vehicle
• NOTE: Check and rectify basic faults before beginning diagnostic routines including pinpoint tests
1. Verify the customer concern by operating the safety belt
1.
2. Visually inspect for obvious signs of mechanical or electrical damage
2.

Inertia Reel Safety Belts
The vehicle is equipped with (two row one), (three row two), and (two row three (seven seat versions only)) inertia reel
safety belts
These safety belts are "dual sensitive" which means that they have:
Car sense system - A vehicle motion sensor, which locks the safety belt webbing under braking, cornering, on
steep hills and in adverse camber conditions, when parked on a steep incline or driveway or two wheels on a
high curb
Webb sense system - A webbing motion sensor, which locks when the safety belt webbing is extracted
suddenly
The safety belts in the following positions are equipped with an automatic locking retractor function:
