module and fuel injector operating data from the ECM.
A 'Trip' button is located on the end of the LH (left-hand) multifunction switch and allows the driver to access, in sequence, the
available trip information by repeatedly pressing the button. The trip information is displayed in the following order:

Trip distance – The trip distance since the last reset is displayed
Average speed – The average speed since the last reset is displayed
Average fuel consumption – The average fuel consumption since the last reset is displayed
Range – The range is displayed showing the distance which can be travelled until the fuel gage reads empty. If the
range display shows dashes (-), this indicates a failure with one or both of the fuel level sensors.

The trip computer has three independent memories; A, B and Auto. Memories A and B can be set independently. The Auto
memory is reset after each ignition cycle and therefore only contains information relating the current journey.

The trip information can also be accessed from the TSD located in the center console. The TSD allows the same information
available with the trip button on the multifunction switch to be displayed on the TSD, with the addition of the option to reset
the values in the A and B memories.
If the battery is disconnected, all trip data in memories A, B and Auto are erased.

Fuel Level Display

The fuel level display is a linear LCD display to show the usable fuel tank contents. The level display is active at all times when the ignition is on. Low fuel level is displayed as a LOW FUEL LEVEL message and an amber warning triangle in the
message center.

The fuel level is obtained by fuel level sensors in the fuel tank. These are monitored by the RJB software and their output resistance values, corresponding fuel quantity, are transmitted to the instrument cluster on the medium speed CAN bus. The instrument cluster uses the two level sensor signals to calculate the fuel tank contents. This calculation takes into account
fuel movement in the tank to display a steady fuel quantity in the LCD.
The fuel level information is transmitted on the medium speed and high speed CAN bus for use by other vehicle system modules.
AUDIBLE WARNINGS

The instrument cluster can generate audible warnings to alert the driver to a displayed message and change of vehicle
operating condition. The audible warning is generated by a sounder located within the instrument cluster. The audible warnings
can be generated for the warnings below and are listed in order of priority, with the first being the highest priority:

Seatbelt reminder
EPB (High Pitch)
ACC Driver Intervene 1
Airbag fault
Key in ignition switch
ASL overspeed
ACC Driver Intervene 2
EPB (Low Pitch)
Vehicle armed (entry delay)
JaguarDrive selector not in park
Valet mode
Lights on reminder
Hood operation
Passive Entry / Passive Start (PEPS)
Memory set
Turn signal indicators
Seat Belt Minder.

The audible warnings can take the form of a single chime, a number of chimes or a continuous chime. The audible warnings are
initiated by a CAN message request from the requesting sub-system control module or by the instrument cluster software.

Leather Seat Covers Published: 20-Nov-2013

Leather is a natural product, therefore it bears natural characteristics, such as grain variations, growth & bush marks. These
non-weakening marks show the true nature of the hide and are the hallmarks of Leather. In order to maintain the beauty of the
vehicles natural Leather upholstery it requires regular cleaning, which if neglected, may cause deterioration. Where dust and
dirt are allowed to accumulate and become ingrained in the surface of the Leather, the upholstery may become permanently
damaged.

Light coloured upholstery can be particularly susceptible to soiling and staining and care should be taken to ensure that where
there is evidence of any soiling or staining on the upholstery then this should be cleaned immediately using the Jaguar/Land
Rover approved products, failure to do this could lead to the stain becoming permanent, this applies to all leather upholstery
and is not colour specific.

Leather trimmed seats will naturally exhibit areas of creasing and wrinkling over a period of time and is a normal characteristic
as the Leather ages.

Particular care should be taken where there is evidence of soiling or staining on the leather, this should be cleaned
immediately. Failure to do this could lead to the stain becoming permanent.
Particular care should be taken to prevent damage from studs, zips and buckles.
NOTES:

Please refer to Leather care label attached to seats for more information.


Creasing and wrinkling does not represent a manufacturing defect.


Damage from studs, zips and buckles do not represent manufacturing defects.


Use only Jaguar/Land Rover approved products in accordance with the instructions for use.

General

A number of front seating options are available. An 8-way electrically adjustable driver's seat is complemented by an 8-way
electrically adjustable passenger seat. A 10-way electrically adjustable driver's seat is complemented by an 10-way electrically
adjustable front passenger seat. A 16-way electrically adjustable driver's seat is complemented by a 12-way electrically
adjustable front passenger seat.

On non-memory seats, the operation of the seats is controlled directly from the driver's seat switchpack. On memory seats,
the operation of the seat motors is controlled by a seat control module which is located on the underside of the driver's seat
frame.

The driver's seat is fitted with a seat position sensor which is located on the seat rail. The sensor is used by the RCM
(restraints control module) to determine the seat position and adjust the inflation time of the airbag deployment accordingly.

Description and Operation

OVERVIEW


WARNING: All pyrotechnic devices are dangerous. Before performing any procedures on any pyrotechnic device, read all
information contained within the Standard Workshop Practices section of this manual.
Refer to: Standard Workshop Practices (100-00 General Information, Description and Operation).
The SRS (supplemental restraint system) provides additional protection for the vehicle occupants in certain impact conditions.
The system is controlled by the RCM (restraints control module), which is mounted beneath the floor console. The system
includes twin stage drivers and front passenger airbags.
The RCM receives inputs from various sensors around the vehicle and determines which, if any, airbags should be deployed.
The SRS features an occupant detection system. The occupant detection system comprises a mat fitted inside the front passenger seat. By monitoring the condition of the mat, the RCM can determine if the front passenger seat is occupied. It uses this information to determine which airbags to deploy in the event of an impact. This information is also used to illuminate the
safety belt instrument cluster warning lamp if the front passenger seat is occupied and the safety belt is not engaged.

North American Specification (NAS) vehicles also feature an occupant classification system. The occupant classification system
comprises a control module, pressure pad and safety belt tension sensor. The system can determine the size and weight of the
front seat passenger. This information is transmitted to the RCM over the high speed CAN (controller area network) bus. The RCM uses this information to help determine which airbags to deploy in the event of an impact.

System Operation System Operation

In a collision, the sudden deceleration or acceleration is measured by the impact sensors and the accelerometers in the
restraints control module. The restraints control module evaluates the readings to determine the impact point on the vehicle
and whether the deceleration/acceleration readings exceed the limits for firing any of the airbags, pretensioners, and battery
disconnect unit. During a collision, the restraints control module only fires the airbags and pretensioners if the safing function
confirms that the data from the impact sensor(s) indicates an impact limit has been exceeded.
The RCM incorporates the following impact thresholds to cater for different accident scenarios: Front impact, pretensioners
Front impact, driver and passenger airbags stage 1, belt unfastened
Front impact, driver and passenger airbags stage 1, belt fastened
Front impact, driver and passenger airbags stage 2, belt unfastened
Front impact, driver and passenger airbags stage 2, belt fastened
Rear impact
Driver side impact
Passenger side impact.

The front impact thresholds increase in severity from pretensioners to driver and passenger airbag stage 2, belt fastened (refer
to list above).

Firing Strategies

The safety belt pretensioners are fired when the pretensioner impact limit is exceeded. The RCM only fires the pretensioners if the related safety belt is fastened.

The driver and passenger airbags are only fired in a frontal impact. If an impact exceeds a stage 1 limit, but is less than the
corresponding stage 2 limit, only one inflator in each airbag is fired (stage 2 is still fired for disposal after a delay of 100ms).
If an impact exceeds the stage 2 limit, the two inflators in each airbag are fired simultaneously.

The passenger airbag is disabled unless the front passenger seat is occupied by a large person (NAS only), or the passenger
airbag deactivation switch is on (all except NAS & AUS).

The stage 2 inflator of the driver airbag is disabled if the driver seat is forward of the switching point of the seat position
sensor.

If there is a fault with a safety belt buckle sensor, the RCM assumes the related safety belt is fastened for the pretensioner firing strategy and unfastened for the driver and passenger airbag firing strategies. If there is a fault with the occupant
classification sensor, the RCM disables the passenger airbag. If there is a fault with the passenger airbag deactivation switch, the RCM disables the passenger airbag.
If a side impact limit is exceeded, the RCM fires the side airbag and the side head airbag on that side of the vehicle. If the side impact limit on the front passenger side of the vehicle is exceeded, the RCM also evaluates the input from the occupant classification sensor, and fires the side airbag only if the front passenger seat is occupied by a large person (NAS only).

If multiple impacts occur during a crash event, after responding to the primary impact the RCM will output the appropriate fire signals in response to any further impacts if unfired units are available.
