Jaguar XJ (2008 year). Manual - part 19

Occupant Protection

*It is possible to receive an intermittent
indicator lamp, with an empty seat
condition. This is part of the system’s
adaptive behaviour, and does not affect
the status of the passenger air bag.
However, if the indicator lamp becomes
permanently illuminated when the seat is
definitely empty and the seat belt is
unbuckled, then contact your nearest
Jaguar Dealer immediately.

Note: The occupancy sensing system is
designed to confirm that a front
passenger is properly seated as
recommended:

•

Always sit centrally in the seat,
remaining in contact with the seat
back which for comfort should be
rearwards of the vertical position.

•

Adjust the seat to be as far back from
the facia as is practical.

•

Always wear seatbelts.

The seat adjustment controls are
described on page 92.

WARNING:

It is important that the passenger
position sensors (see illustration) are
not obscured in any way which could
affect air bag deployment, e.g. fitting
non-approved accessories.

WARNING:

Crash test data and statistics, show
that the safest place for a child to be
restrained, is in a child seat correctly
fitted to the vehicle's rear seat.

WARNING:

Do not use a child restraint on a seat
protected by an operational air bag in
front of it. Doing so presents a high risk
of death or serious injury to the child in
the event of an accident.

WARNING:

Do not fit a child restraint to the front
passenger seat if the SRS warning
indicator illuminates continuously with
the ignition on.

Occupant Protection

Air bag deactivation warning indicator
(Yellow)

The PASS AIR BAG OFF warning
indicator on the passenger facia is
associated with the deployment
conditions for the front seat passenger air
bag only.
• The warning indicator will NOT be lit if

the seat is empty and the front air bag
will not be activated.

• The warning indicator will NOT be lit if

the seat is occupied by a larger child
or an adult. The front air bag will be
activated and will be deployed in the
event of a frontal impact.

• The PASS AIR BAG OFF warning

indicator WILL be lit if the seat is
occupied by, for example, a small
child and in this case the front air bag
will not be activated.

• If the passenger adopts a posture

(e.g. leaning very far forward) which
could cause injury from an inflating air
bag, the PASS AIR BAG OFF warning
indicator WILL be lit and the front air
bag will not be activated.

Note: Whenever the PASS AIR BAG OFF
warning indicator on the passenger facia
is illuminated, the front passenger air bag
will not be deployed in the event of an
impact.

Driving position

WARNING:

Driver and front seat passenger should
always move their seats as far
rearwards as is practical.

Since the risk zone at the time of
deployment is the first
55 mm – 75 mm (2 to 3 inches) from the
air bag cover, sitting back 254 mm (10
inches) provides a clear margin of safety.
Very few drivers are unable to achieve and
maintain that safety gap.

The vast majority of drivers who do not
now sit that far back can change their
position and achieve that distance.

Occupant Protection

• Use seat belts.

• If adjustable pedals are fitted, move

them towards the seat.

• Move your seat as far rearwards as

you can while still comfortably
reaching the pedals.

Recline the back of your seat one or
two notches from the upright position.
If reclining the back of your seat
makes it hard to see the road, raise
the seat.

• Tilt the steering wheel/column

downwards so as to point the air bag
at your chest instead of your head and
neck. Adjust the steering wheel/
column fore/aft so that it extends
towards the driver as little as possible,
ensuring that the air bag has plenty of
room to deploy.

Occupant Protection

• Sit in the centre of the seat with the

head as close to the head restraint as
possible.

* Ideally, drivers should sit with at least
254 mm (10 inches) between the centre of
their breastbone and the cover of the
steering wheel air bag.

WARNING:

Adjust the head restraint so that it is
just behind your head and never behind
your neck.

Note: Seat, steering wheel and pedal
adjustment controls are described later in
this section, pages 92, 98 and 100
respectively.
