Occupant Protection

R

If the belt has any slack in the lap strap
this must be removed by pulling firmly
upwards on the shoulder strap of the seat
belt thus tightening the belt and safely
securing the occupant.

!

WARNING:

Do not use the belt clip to introduce
slack into the seat belt. To be fully
effective, the seat belt must remain in
full contact with the body at all times.

Pregnant Women

!

WARNING:

Position the seat belt correctly for the
safety of the mother and unborn child.
Never wear just the lap strap, and
never sit on the lap strap whilst using
just the shoulder strap. Both of these
actions are extremely dangerous, and
may increase your risk of serious injury
in the event of an accident or during
emergency braking.

!

WARNING:

Never place anything between you and
the seat belt in an attempt to cushion
the impact in the event of an accident.
It can be dangerous, and will reduce
the effectiveness of the seat belt in
preventing injury.

Position the lap strap comfortably across
the hips beneath the abdomen. Place the
diagonal part of the seat belt between the
breasts and to the side of the abdomen.
Ensure that the seat belt is not slack or
twisted.

RESTRAINTS SYSTEMS

Advanced Restraints Technology
System (ARTS)

In order to provide optimum protection
this vehicle is equipped with front, side
and curtain air bags. They are used in
conjunction with the seat belts to help
protect occupants from upper body
(thorax) and head injuries.

1. The driver front air bag is located in

the centre of the steering wheel.

2. The front passenger air bag is located

in the facia panel immediately in front
of the passenger seat.

3. Curtain air bags are fitted on each

side, above the front and rear doors.

4. Thorax and pelvis side air bags are

fitted within the outboard bolsters of
both front seats, and are identified by
labels.

WARNING:

High speed impacts may cause serious
injury or death irrespective of safety
features fitted to a vehicle. Always
drive with caution and consideration
for the vehicle's characteristics, road
and weather conditions, and do not
exceed any speed limits in force.

!

WARNING:

Seat belts should be worn at all times,
by the driver and passengers in all
seating positions. The air bag SRS
cannot provide protection in some
types of impact. Under these
circumstances the only protection will
be provided by a correctly worn seat
belt.

!

WARNING:

Air bags inflate at high speeds, and can
cause injuries. To minimise the risk of
injury, ensure that all vehicle
occupants wear correctly positioned
seat belts, sit correctly in the seats,
and position the seats as far back as
practical.

!

WARNING:

Ensure that a gap is maintained
between the side of the vehicle, and the
head and torso. This will enable
unobstructed inflation of the curtain,
and seat mounted side air bags.

!

WARNING:

Air bag inflation takes place
instantaneously, and cannot protect
against the effects of secondary
impacts. Under these circumstances
the only protection will be provided by
a correctly worn seat belt.

!

WARNING:

Phone systems should only be installed
by qualified persons familiar with the
operation of, and requirements for,
vehicles fitted with SRS. If you are in
any doubt, seek advice from your
Jaguar Dealer.

Air bag warning information is printed on
the driver’s and passenger’s sun visor.

The air bags and seat belt pretensioners
are electrically controlled by an advanced
restraints technology system.

Both front air bags use a dual inflation
technology. When activated, the bag(s)
will deploy at either a normal or reduced
level of inflation, depending on crash
severity. The lower inflation level is also
selected if the restraint system senses
that the seat occupant is too close to the
air bag.

Various sensors determine the direction
and severity of an impact and the
presence and position of front seat
occupants.

The system analyses this information then
deploys the appropriate air bags only e.g.
the side air bags where the impact is on
that side only.

Air bags are not deployed in a rear impact.

!

WARNING:

For the air bags to operate correctly
the roof lining and door post trims must
be in good condition, correctly fitted,
and free from obstruction. Any
damage, wear, or incorrect fitment
should be referred to your Jaguar
Dealer as soon as possible for
examination and repair.

!

WARNING:

Do not allow passengers to obstruct
the operation of the air bags by placing
any part of their person, or any objects,
in contact with, or close to, an air bag
module. Air bags deploy at very high
speeds, and can cause serious injury
or death if objects or occupants are
within the area of deployment.

Disability modifications

Occupants with disabilities that may
require the vehicle to be modified, must
contact a Jaguar Dealer before any
modifications are made.

Air bag fault warning indicator

The air bag warning indicator
in the driver’s instrument
panel will be lit for
approximately six seconds
when the ignition is turned on.

If the indicator remains on or flashes, it
indicates a fault within the air bag
electrical circuits. Report the fault to a
Jaguar Dealer immediately. It is safe to
drive the vehicle; however, in an accident
the air bags may not operate.

The following components are monitored
by the air bag system:
• Driver’s and passenger’s dual stage

air bag

• Driver’s and passenger’s side thorax

air bag

• Driver’s and passenger’s

pre-tensioner

• Driver’s and passenger’s side crash

sensor - 4 off

• Passenger’s seat occupancy sensor
• Restraint control module

!

WARNING:

If the warning indicator signals that a
fault is present in the system, do not
use a child restraint on the front
passenger seat. Doing so will increase
the risk of death or serious injury to the
child.

Air bag warning indicator information is
shown on page 117.
