On vehicles installed with a driver's power operated memory seat and memory exterior mirrors, a potentiometer is incorporated
within each mirror motor and is used to provide information regarding the actual motor positions. The current position and
memory positions of each door mirror motor are maintained and stored within the corresponding door control module.

The memory exterior mirror positions are also monitored and stored within door control module memory when the reverse gear
mirror dip function is used.

When reverse gear is selected, the door control module stores the current mirror positions and will then dip the passenger
mirror glass to a default dip position. While reverse gear is selected it is possible to store a preferred dipped mirror position by
adjusting the driver/passenger mirror glass to the desired position via the mirror switch pack. When the desired position is
achieved using the switch, the new dip positions will be automatically stored by the door control module when reverse gear is
de-selected. Therefore when reverse gear is re-selected, the dip position recalled by the door control module will be the new
reverse gear mirror dip stored position. When reverse gear is deselected the mirror glass will automatically move to the previous
stored position prior to reverse gear selection.

If the driver selects a memory recall function using the memory seat switch pack, the driver's memory seat and exterior
memory mirrors are moved to a stored memory position.

Exterior mirrors with the power fold/auto fold feature incorporate a motor located in the hinge of each exterior mirror arm.
Operation of the power fold feature is achieved using the exterior mirror switch pack. Operation of the auto fold feature is
achieved using the remote handset.
The power fold function is active when the ignition is in power mode 6 (Ignition).

Both exterior mirrors will power fold when the mirror switch pack 'L' and 'R' switches are pressed together. Pressing the
switches again will unfold the mirrors.

When the instrument cluster is configured for the auto fold feature, the mirrors will fold in when the remote handset lock
button is pressed. The mirrors will unfold when the vehicle is unlocked using the remote handset unlock button.


NOTE: If the mirrors are folded in using the mirror switch pack (power fold) and the vehicle is then locked, subsequent
unlocking of the vehicle will not unfold the mirrors.

When the remote handset unlock button is operated, the CJB recognizes the remote handset for that vehicle and acknowledges the request. The door control modules are connected directly to the AJB (auxiliary junction box) for power supply to the
exterior mirror folding motors.

When the vehicle is locked the door control modules reverse the polarity of the mirror fold motor, power and ground
connections to operate the mirrors in the opposite direction.

Exterior mirror heating is provided with heater elements bonded to the back of the mirror glass. Power supply for the mirror
heating elements is provided by the corresponding driver or passenger door control module via the RJB. The door control modules receive a power supply from the RJB, and are both connected on the medium speed CAN bus to the ATC (automatic temperature control) module. A ground terminal from each door control module completes the circuit. The ATC module automatically controls the mirror heating function whenever the ignition is in power mode 4 (Accessory) and power mode 6
(Ignition).

Operation of the exterior mirror heaters is fully automatic and not controllable by the driver. Exterior mirror heater operation is
determined by ambient air temperature and windshield wiper status. When ambient air temperature reaches a pre-determined
level, the ATC module broadcasts an exterior mirror heating request to the door modules over the medium speed CAN bus. On receipt of this message, the door modules provide feed and ground connections to both exterior mirror heater elements.

The mirror heating is controlled in two phases, the initial heating phase and a second PWM (pulse width modulation) controlled
phase. In the first phase the heater elements in the mirrors are permanently powered for a pre-determined length of time. This
length of time varies with the ambient temperature. During the second PWM phase, the heater elements are turned on and off every 30 seconds. The amount of time the exterior mirror heaters are operational increases if the windshield wipers are
switched on. This ensures the mirrors remain mist free in damp and wet conditions, where there is an increased risk of misting.

OVERVIEW

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.

HEATED SEATS - OPERATION

Heated Front Seats System Operation

The TSD receives a fused power supply from the RJB. One of the 3 seat heat temperature selections made by the driver or passenger using the TSD soft keys are passed from the TSD on the MOST ring to the Information and Entertainment module.
The information and entertainment module processes the information and transmits the request on the medium speed CAN bus to the ATC module.
The cushion heaters have a thermal sensor which supplies a feed back signal back to the CJB. The squab heater elements do not have a thermal sensor and are maintained at the same temperature as the seat cushion elements.

The ATC module reacts to the driver request information received from the information and entertainment module and requests the CJB to activate the seat heaters. The CJB measures the returned temperature signals from the thermal sensors and relays the temperature signals back to the ATC module. The ATC module then uses the measured seat element temperatures to provide closed-loop control of the heater elements to maintain the temperature at one the 3 heat ranges selected.


NOTE: To prevent excessive battery discharge, the heated front seats will only operate when the engine is running.

Heated and Cooled Front Seats

The TSD receives a fused power supply from the RJB. Selections made by the driver using the TSD soft keys are passed from the TSD on the MOST ring to the Information and Entertainment module. The information and entertainment module processes
the information and transmits the request on the medium speed CAN bus to the front seat climate control module. The front seat climate control module is located beneath the RH (right-hand) front seat, on the floor cross member.

The front seat climate control module receives its power supplies from the CJB. Heating and cooling requests are generated using the soft buttons on the TSD. These requests are transmitted to the information and entertainment module over the
MOST ring. The Information and Entertainment module forwards these requests to the front seat climate control module over
the medium speed CAN bus.
The front seat climate control module supplies power to the two climate modules in each seat. The temperature sensor in each
climate module is monitored by the front seat climate control module which uses the temperature information to control the
Peltier cells accordingly and also the blower fans to distribute the heated or cooled air.


NOTE: To prevent excessive battery discharge, the heated and cooled front seats will only operate when the engine is
running.
Electric Driver's Seat Adjustment - Non-Memory Seats

The CJB supplies 3 power supplies to the driver's seat switchpack. The fused supplies provide power for the seat height and squab recline, the seat slide and seat tilt and the lumbar adjustment respectively. The CJB only provides the power to the driver's seat switch pack when the ignition is on (power mode 6).

For the seat movement motors, when the applicable switch is operated, the power is supplied to the applicable side of the
motor and the ground path is completed to operate the motor in the required direction. To move the motor in the opposite
direction the polarity is reversed.

For the lumbar adjustment, when the switch is operated in the inflate position, power is supplied to the pump motor to inflate
the lumbar support. When the switch is operated in the opposite direction, the power energizes a solenoid which in turn opens
a valve to deflate the lumbar support.
Electric Passenger Seat Adjustment ( 8, 10 and 12 way)

The CJB supplies 3 power supplies to the passenger seat switchpack. The fused supplies provide power for the seat height and squab recline, the seat slide and seat tilt and the head restraint and lumbar adjustment respectively. The CJB only provides the power to the passenger seat switch pack when the ignition is on (power mode 6).

For the seat movement and head restraint motors, when the applicable switch is operated, the power is supplied to the
applicable side of the motor and the ground path is completed to operate the motor in the required direction. To move the

supplies provide power for the movement motors in addition to the driver's seat switch pack. Power is only supplied to the
driver's seat module and the driver's seat switch pack when the ignition is on (power mode 6).

The driver's seat switch pack is connected to the driver's seat module by a LIN bus for the seat movement switches. Any selection for seat movement generates a message which is passed via the LIN to the driver's seat module. The seat module processes the request and operates the applicable seat function as required using the power supplies from the CJB.
Each seat motor contains a Hall position sensor. The sensor sends a feedback signal to the driver's seat module. The signal is
used for memory store and memory recall functions.

The lumbar adjustment switch on the driver's seat switch pack is wired direct to the lumbar pump and solenoids. The switch,
when moved to the inflate position for either the upper or lower inflatable cushion cell, provides a power supply to the lumbar
pump and simultaneously activates the applicable inflate solenoid valve. When the switch is released the pump stops and the
solenoid valve closes trapping the air in the inflatable cushion. When the switch is moved to the deflate position for either the
upper or lower inflatable cushion cell, power is supplied to the applicable deflate solenoid valve which opens to allow the air in
the cushion to escape. When the switch is released, the valve is closed and the remaining air in the cushion is retained.



FRONT SEATS - DESCRIPTION Component Description

The table below highlights the features available for each seating option.

Seat Type Non-Heated Heated Heated and Cooled Lumbar Support Memory 8-way Yes Optional No 2-way No 10-way Yes Optional Optional 2-way Optional (Driver's seat only) 12-way No No Yes 4-way No 16-way No No Yes 4-way Yes (Driver's seat only) Seat Heating

The 3-stage heated front seats feature 2 heater elements located in the seat cushion and a single heater element located in
the seat squab. Operation of the heated front seats is controlled by the ATC module via the TSD, information and entertainment control module and the CJB module on vehicles with heated seats. On vehicles with heated and cooled seats the operation is controlled by the TSD, information and entertainment control module and the front seat climate control
module.

The heated and cooled front seats each contain 2 climate modules; one in the cushion, one in the squab. The climate modules
contain 'Peltier' cells which are able to deliver heating and cooling based on a voltage provided by the front seat climate
control module. Each climate module also contains a fan, which blows air over the Peltier cells to distribute heated or cooled
air via liners in the seat cushion and squab. The fan is also controlled by the front seat climate control module. The TSD allows
the driver and passenger to select 3 ranges of heated or cooled ventilation; off, minimum and intermediate. Also, using the
selections on the TSD, the driver and passenger can select between full seat ventilation or squab backrest ventilation only.

Vehicles fitted with the 3-stage heated front seat option also feature a heated steering wheel.
Refer to: Steering Column Switches (211-05 Steering Column Switches, Description and Operation).
Electric Seat Adjustment

Lumbar Support

On 8, 10 and 12 way seats, a 2 way lumbar support is provided which allows the lumbar inflatable cushion to be inflated or
deflated as required. On 16 way seats, a 4 way lumbar support is fitted which comprises two separate cushion cells. The upper
and lower cells can be inflated or deflated individually allowing greater comfort adjustment for the driver and passenger.

The lumbar support comprises an inflatable cushion located in the seat squab, a pump and solenoids. The pump is activated
when the applicable seat switch is moved to the inflate position, inflating the cell(s) in the inflatable cushion. On 8 and 10
way seats, a single solenoid operated valve allows the inflatable cushion to be deflated. On 12 and 16 way seats, 4 solenoid
valves control the inflation and deflation of the upper and lower inflatable cushion cells, allowing each cell to be adjusted
individually.
Seat Motors

The head restraint motor is located in the upper section of each seat squab and is accessible by removal of the seat back. The
motor moves a cradle which is driven in a vertical motion by a rack and pinion arrangement. The cradle has the two head
restraint stems attached to it and therefore raises and lowers the head restraint as the motor moves the cradle. The motor
contains a Hall sensor which supplies positional information to the driver's seat module.

The seat slide motor is an integral component of the seat frame. The motor drives on a gear on a worm drive lead screw which
is integral with the floor rail. The lead screw has a stop at each end to limit the fore and aft seat movement.
