1999 LAND ROVER DISCOVERY child seat

GENERAL INFORMATION
03-19
WARNING: Do not use rear facing child seats in
the front passenger seat if the vehicle is fitted
with a passenger airbag.
WARNING: It is imperative that before any work
is undertaken on the SRS system the appropriate
information is read thoroughly.
WARNING: Replace the airbag every 10 years.
Do not install used SRS parts from another car.
When repairing an SRS system, always use
approved new parts.
Carefully inspect the airbag module before
installing it. Do not install an airbag module that
shows signs of being dropped or improperly
handled, such as dents, cracks or deformation.
Do not try to disassemble or tamper with the
airbag module.
Special bolts are necessary for installing the
airbag module. Do not use other bolts.
Preliminary procedures
The SRS system uses energy reserve capacitors
that keep the system active in the event of electrical
supply failure under crash conditions. It is necessary
to allow the capacitors sufficient time to discharge in
order to avoid the risk of accidental deployment.
Always remove the ignition key from the starter
switch, disconnect the vehicle battery and wait 10
minutes before commencing work on the SRS
system.
Carefully inspect any SRS component before
installation. Do not install any SRS component that
shows signs of damage such as dents, cracks or
deformity.Component handling
The SRS components are sensitive and potentially
hazardous if not handled correctly; always comply
with the following handling precautions:
lNever drop an SRS component. The airbag
Diagnostic Control Unit (DCU) is a particularly
shock sensitive device and must be handled
with extreme care. Airbag modules and seat belt
pretensioner units could deploy if subjected to a
strong shock.
lNever wrap your arms around an airbag
module. If an airbag module has to be carried,
hold it by the cover, with the cover uppermost
and the base away from your body.
lNever transport airbag modules or seat belt
pretensioners in the cabin of a vehicle. Always
use the luggage compartment of the vehicle for
carrying airbag modules and seat belt
pretensioner units.
WARNING: The airbag module contains sodium
azide which is poisonous and extremely
flammable. Contact with water, acid or heavy
metals may produce harmful or explosive
compounds. Do not dismantle, incinerate or
bring into contact with electricity, before the unit
has been deployed.

Rotary coupler
Always follow the Repair procedure for fitting the
rotary coupler.
Comply with all safety and installation procedures to
ensure the system functions correctly. Observe the
following precautions:
lDo not install a rotary coupler if it is suspected to
be defective.
lDo not attempt to service, modify or repair a
rotary coupler.
lDo not cut, splice or modify the wires attached
to yellow SRS connector and lead.
lAlways ensure the rotary coupler connectors
are mated correctly and securely fastened.
lAlways ensure the battery is disconnected
before working on the rotary coupler.
lAlways ensure the rotary coupler is removed
and installed in its centered position and with the
front road wheels in the straight ahead position.
lIf a new rotary coupler is being installed, ensure
the locking tab holding the coupler's rotational
position is not broken; units with a broken
locking tab should not be used.
Warning labels
Warning symbols are displayed at various positions
in the vehicle (either in a suitable prominent position
such as driver and passenger side glass, or attached
to the component itself) to indicate SRS items which
must be treated with particular care. Exact positions
of SRS warning labels may vary dependent on
legislation and market trends.
WARNING: It is imperative that before any work
is undertaken on the SRS system the appropriate
information is read thoroughly.Side window label

SUNROOF
DESCRIPTION AND OPERATION 76-6-13
Operation
Ignition switched-off timeout
There are three timeout modes for operating the sunroof assemblies after the ignition is switched off. The BCU
determines the vehicle's timeout mode. The three modes are:
lWhen the ignition is switched off, no sunroof operation is permitted.
lWhen the ignition is switched off, sunroof remains functional for 45 seconds or until the driver door is opened.
lWhen the ignition is switched off, sunroof remains functional for 45 seconds or until any door is opened.
Sunroof open and close
Both sunroof assemblies operate in the same manner. The front sunroof assembly has one switch while there are
two switches to control rear sunroof assembly, a rear sunroof front switch and a rear sunroof rear switch.
The sunroof ECU monitors the position of the sunroof microswitch to determine if the sunroof is to be tilted or opened.
In order for the sunroof to operate, either of the following conditions must exist:
lIgnition switch in position II.
lIgnition switched from on to off, doors closed (this may enable the system to operate for 45 seconds after the
ignition is switched off, or until a door is opened).
When the sunroof is closed, pressing the rear of the sunroof switch causes the sunroof ECU to operate the sunroof
motor and open the sunroof. When the sunroof opens, the sunroof microswitch opens. The sunroof continues to
open until the switch is released or the sunroof reaches the fully open position.
When the sunroof is open, pressing the front of the sunroof switch causes the sunroof ECU to operate the sunroof
motor and close the sunroof. The sunroof ECU continues to operate the motor until the sunroof microswitch closes.
This indicates to the sunroof ECU that the sunroof is fully closed.
Sunroof tilt
Both sunroof assemblies operate in the same manner. The front sunroof assembly has one switch while there are
two switches to control rear sunroof assembly, a rear sunroof front switch and a rear sunroof rear switch.
The sunroof ECU monitors the position of the sunroof microswitch to determine if the sunroof is to be tilted or opened.
In order for the sunroof to operate, either of the following conditions must exist.
lIgnition in position II.
lIgnition switched from on to off, doors closed (this may enable the system to operate for 45 seconds after the
ignition is switched off, or until a door is opened).
When the sunroof is closed and the front of the sunroof switch is pressed, the sunroof ECU detects the combination
of closed microswitch and front of sunroof switch being pressed and tilts the rear of the sunroof. This causes the
microswitch to open. The sunroof continues to open until the switch is released or the sunroof reaches the fully open
position.
When the sunroof is tilted and the rear of the sunroof switch is pressed, the sunroof ECU detects the combination of
open microswitch and rear of sunroof switch and closes the sunroof until the microswitch closes. This indicates to the
sunroof ECU that the sunroof is fully closed.
Rear sunroof isolation
The rear sunroof isolation switch prevents the rear sunroof rear switch from operating the rear sunroof. This can be
used to prevent small children sitting in the rear seat from playing with the rear sunroof.
Pressing the rear sunroof isolation switch opens the circuit between the rear sunroof rear switch and the sunroof ECU.
The sunroof ECU ignores the rear sunroof switch until the rear sunroof isolation switch is pressed and the circuit
closes.
