Seat belts

PRINCIPLE OF OPERATION
Seat beltsSeat belt safety
WARNINGS
Seat belts are designed to bear upon
the bony structure of the body, and
should be worn low across the front
of the pelvis or the pe lvis chest and shoulders,
as applicable; wearing the lap section of the
belt across the abdominal area must be
avoided.
Seat belts should be adjusted as
firmly as possible, consistent with
comfort, to provide the protection for
which they have been designed. A slack belt
will greatly reduce the protection afforded to
the wearer.
Care should be taken to avoid
contamination of the webbing with
polishes, oils and chemicals, and
particularly battery acid . Cleaning may safely
be carried out using mild soap and water.
The belt should be replaced if
webbing becomes frayed,
contaminated or damaged.
It is essential to replace the entire
assembly after it has been worn in a
severe impact even if damage to the
assembly is not obvious.
Belts should not be worn with the
straps twisted.
E82942
WARNINGS
Do not carry hard, fragile or sharp
items between your person and the
seat belt. In an impact, the pressure
from the seat belt on such items can cause
them to break, which in turn may cause death
or serious injuries.
Each belt assembly must only be used
by one occupant; it is dangerous to
put a belt around a child being carried
on the occupant's lap.
The occupants of the front seats
should not travel with the seat back at
more than 30 degrees from upright.
Doing so will reduce the protection afforded by
the seat belt.
WARNINGS
Seat belts should be worn by all
vehicle occupants, for every journey,
no matter how short. Failure to do so,
will greatly increase the risk of death or
serious injury in the event of an accident.
Never wear just the la p belt or just the
shoulder belt of a lap/shoulder
diagonal seat belt. Both of these
actions are extremel y dangerous and may
increase your risk of injury.
No modifications or additions should
be made by the user which will either
prevent the seat belt adjusting
devices from operating to remove slack, or
prevent the seat belt assembly from being
adjusted to remove slack.
A slack seat belt offers a greatly reduced level
of occupant protect ion in an impact.

Seat belt checks
Note: If the vehicle is parked on an incline, the
seat belt mechanism may lock. This is not a
fault and the belt should be gently eased out
from the upper anchorage.
The seat belts should be inspected regularly to
check for fraying, cuts or wear to the webbing,
and the condition and security of the
mechanism, buckles, adjusters, and mounting
points.
• With the seat belt fastened, give the
webbing near the buckle a quick upward
pull. The buckle must remain securely
locked. •
With the seat belt unfastened, unreel the
seat belt to the limit of its travel. Check that
it unreels smoothly with no snatches or
snags. Allow the belt to fully retract, again
checking for smooth operation.
• Partially unreel the seat belt, then hold the
tongue plate and give a quick forward pull.
The mechanism must lock and prevent any
further unreeling.
If any of the seat belts fail to meet those
criteria, immediately contact your Dealer/
Authorised Repairer.
SEAT BELT REMINDER
If the driver's seat belt is not
fastened when the vehicle is in
motion, a chime will be heard and
the seat belt warning i ndicator will illuminate.
The warning chime and indicator will also be
activated if the front passenger seat is
occupied without the seat belt being fastened.
Note: Objects placed on the front passenger
seat may activate the seat belt reminder
warning chime and i ndicator. It is
recommended that any objects placed on the
front passenger seat are secured using the seat
belt.
If any damage, wear, cuts, defects or
impaired operation are noted with the
seat belts, the vehi
cle should be taken
to a Dealer/Authorised Repairer for immediate
attention. Do not use th e vehicle if the seat
belts cannot be operated correctly.
When using seat belts to restrain
items other than occ upants, take care
to ensure that the belts are not
damaged, or exposed to sharp edges.
Care must be taken to avoid
contaminating the seat belt webbing
and seat belt mechanisms with any
chemicals, liquids, gr it, dirt or cleaning
products. If the seat belts do become
contaminated, they should be replaced
immediately. Contaminat ed seat belts my not
operate correctly in an impact and cannot be
relied upon.
The use of comfort clips, or devices
that would create slackness in the
seat belt system, is not advised.

WARNINGS
High speed impacts may cause
serious injury or de ath irrespective of
safety features fitted to a vehicle.
Always drive with caut ion and consideration
for the vehicle's characteristics, road and
weather conditions.
The airbag cannot provide protection
in some types of impact, therefore
seat belts s hould be worn at all times
by the driver and passengers in all seating
positions.
WARNINGS
Airbags inflate at high speeds, and
can cause injuries. To minimise the
risk of injury, ensure that all vehicle
occupants wear correct ly positioned seat
belts, sit correctly in the seats, and position
the seats as far back as practical.
Sitting centrally and correctly in each
seating position helps ensure that a
gap is maintained between the side of
the vehicle and the head and torso. This will
aid inflation of the curtain and seat-mounted
airbags.
Airbag inflation takes place
instantaneously. Not all airbags are
designed to protect against the
effects of se condary impacts. During
secondary impact, a leve l of protection may be
provided by a correctly worn seat belt.

Supplementary restraints system

Note: The general location of airbags fitted to
the vehicle are marked by the word AIRBAG.
Always contact your Dealer/Authorised
repairer if:-
• An airbag inflates.
• The front or sides of the vehicle are
damaged.
• Any part of the SRS shows signs of
cracking or damage, including trim
covering airbags.
Airbag operation
Airbags cannot deploy co rrectly if they are
obstructed. Examples of obstructions are:-
• Any part of an occu pants body in contact
with, or close to, an airbag covering.
• Objects placed on, or close to, an airbag
cover.
• Clothing, sun screens, or other material
hanging from grab handles.
• Clothing, cushions, or other material,
covering seat mounted airbags.
• Seat covers which are not approved by
Jaguar, or specifical ly designed for use
with seat mounted airbags.
• Luggage that intrudes into the area that
will be occupied by a deploying airbag
system.
This list is not exhausti ve and it remains the
responsibility of the driv er and passengers to
ensure that the airbags are not obstructed in
any way.
Deployment and deflation
In the event of a collisi on, the restraints control
system monitors the rate and direction of
deceleration. If required to supplement the seat
belts, airbags will be deployed as appropriate.
After operation, frontal airbags do not retain
pressure.
Front airbags
The front passenger’s and driver’s airbags are
able to deploy in two stages, depending on the
severity of the frontal impact. In a severe
impact, the airbags inflate fully to offer
maximum protection. In a lower severity
impact, less inflation ma y be required, so the
airbags inflate in a different manner.
WARNINGS
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/Authorised repairer.
WARNINGS
For the airbags 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 fitmen t should be referred to
your Dealer/Authorised repairer as soon as
possible for examination and repair.
Do not allow passe ngers to obstruct
the operation of the airbags by
placing any part of their person, or
any objects, in contact with, or close to, an
airbag module. Airbags deploy at very high
speeds and can cause se rious injury or death
if objects or occupants are within the area of
deployment.

Side and curtain airbags
To ensure that the side and curtain airbags are
fully effective:
Side and curtain airbags are designed to offer
increased protection for the torso and head in
a side impact. The curtain airbags may deflate
at a slower rate than the front or side airbags,
to afford prolonged protection.
Airbag deployment effects
WARNINGS
Do not allow passe ngers to obstruct
the operation of the airbags by
placing any part of their person, or
any objects, in contact with, or close to, an
airbag module. Airbags deploy at very high
speeds and can cause se rious injury or death
if objects or occupants are within the area of
deployment.
Do not sit too close to, lean or
sleep against the door trim. The
side and curtain airbags could
injure you as they deploy.
Do not lean out of the window.
Only use approved accessories (e.g.
seat covers).
Due to the function of the curtain
airbag deployment, consult your
Jaguar Dealer/Autho rised Repairer,
prior to installing any accessories in the upper
environment/pillar trim area (e.g. hands-free
telephone kits).
WARNINGS
When an airbag inflates, a by-product
of the gas generation may be released
as small particles. It is possible that
this may cause irritation and should be
thoroughly flushed from th e eyes and any cuts
or abrasions.
After inflation, some airbag
components are at high
temperatures. To prevent injury, do
no touch the airbag components until they
have cooled.
In order to react with sufficient speed,
airbags are deployed by a pyrotechnic
device. Consequently, airbag
deployment is accomp anied by a very loud
noise which may caus e discomfort and
temporary loss of hearing.

AIRBAG WARNING LAMP
The airbag warning indicator is
mounted in the instrument pack,
and will illuminate as a bulb check
when the starter switch is turned on.
If any of the following warning indicator
conditions occur, the vehicle should be
checked by your Dealer /Authorised repairer
immediately.
• The warning indicator fails to illuminate
when the starter switch is initially turned
on.
• The warning indicator fails to extinguish
within six seconds of the starter switch
being turned on.
• The warning indicator illuminates at any
time other than the bulb check, when the
starter switch is on.
WHIPLASH PROTECTION
Both front seats are equi pped with Active Head
Restraints (AHR), which reduce the risk of neck
and spinal injury (whiplash) in the event of a
rear impact.
When activated, the head restraint moves
upwards and forwards, supporting the
occupant's head.
After activation, the whiplash protection
mechanism automatically resets and does not
need to be replaced.
WARNING
If the warning indica tor 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.

Child safety

CHILD SEATS
The seat belts fitted to your vehicle are
designed for adults and larger children. For
their safety, it is very important for all infants
and children under 12 years of age to be
restrained in a suitable child safety seat
appropriate to their age and size.
Children are always safest when seated in a
rear seating position.
If it is essential that a child travels in the front
passenger seat, Jaguar recommends that the
following preparations are made before fitting
the child restraint.
• Adjust the front passenger seat fully
rearwards.
• Adjust the lumbar support to its minimum
support position.
• Adjust the seat cushion to its highest
position. If cushion front tilt adjustment is
possible, adjust it to its lowest position.
• Adjust the seat back to the fully upright
position.
• Adjust the seat be lt adjustable upper
anchorage to its lowest position.
In some countries, legislation prohibits
children travelling in the front of a vehicle.
Ensure that you are familiar with the legislation
in force where the vehicle is being used and are
in full compliance.
WARNINGS
Do not use a child restraint on a seat
protected by an airbag in front of it.
There is a risk of death or serious
injury when the airbag deploys.
Crash statistics show that children
are safest when properly restrained in
a child or infant restraint system that
is secured in a rear seating position.
For optimum safety , children should
travel in the rear of the vehicle at all
times; front passenge r seat travel is
not recommended. However, if it is
essential that a child travels in the front, set the
vehicle seat fully rearward and seat the child in
an approved forward-facing child seat. Do not
use a rear-facing child seat - an inflating airbag
could impact with the seat and cause serious
injury.
Do not use a forward facing child seat
until the child using it is above the
minimum weight of 9 kg (20 lb.) and
able to sit up unaided. Up to the age of two, a
child's spine and neck are not sufficiently
developed to avoid injury in a frontal impact.
Do not allow a baby or infant to be
held or carried on the lap. The force of
a crash can increase effective body
weight by as much as thirty times, making it
impossible to hold onto the child.
Children typically require the use of a
booster seat appropriate to their age
and size, thereby enabling the seat
belts to be properly fitted, reducing the risk of
injury in a crash. Children could be
endangered in a crash if their child restraints
are not properly secured in the vehicle.Do not use a chil d seat that hooks
over the seat back. This type of seat
cannot be satisfacto rily secured and
is unlikely to be safe for your child.
