PRINCIPLE OF OPERATION

Introduction

In the event of a collision the airbag control unit 
monitors the rate of deceleration caused by the 
collision. This information is then used to 
determine whether airbags should be 
deployed.

Airbag deployment is dependent on the rate at 
which the passenger compartment changes 
speed following the collision. The 
circumstances affecting different collisions 
(vehicle speed, angle of impact, type and size 
of object hit, etc) vary considerably, and will 
affect the rate of deceleration accordingly.

The Supplementary Restraint System (SRS) 
components include :-
• SRS warning indicator.
• Rotary coupler.
• Airbag modules.
• Seat belt pre-tensioners.
• Airbag diagnostic control unit.
• Crash sensors.
• Airbag wiring harnesses.
• Seat occupancy sensor.
Note: The SRS is not designed to operate as a 
result of:
• Rear impacts.
• Minor front impacts.
• Minor side impacts.
• Heavy braking.
• Driving over bumps and pot holes.
Therefore, it follows that considerable 
superficial damage to the vehicle can occur 
without causing the airbags to deploy.

WARNINGS

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.

Seat belts should be worn at all times, 
by the driver and passengers in all 
seating positions. The airbag SRS 

cannot provide protection in some types of 
impact. Under these circumstances the only 
protection will be provided by a correctly worn 
seat belt.

Airbags 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.

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 airbags.

Airbag 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.

WARNINGS

Note: The location points of airbags fitted to 
the vehicle are marked by the word AIRBAG 
embossed into the trim.

Always contact your Land Rover 
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 correctly if they are 
obstructed. Examples of obstructions are :-
• Any part of an occupants body in contact 

with, or close to, an airbag cover.

• 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 

Land Rover, or specifically designed for 
use with seat mounted airbags.

This list is not exhaustive, and it remains the 
responsibility of the driver and passengers to 
ensure that the airbags are not obstructed in 
any way.

Deployment and deflation

In the event of a collision the airbag control 
system monitors the rate, and direction of 
deceleration. If required to supplement the seat 
belts, airbags will be deployed as appropriate.

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 lesser impact full 
deployment is not required, so the airbags are 
partially inflated.

Side and curtain airbags

Side and curtain airbags are designed to offer 
increased protection for the torso and head in 
a side impact. The curtain airbags deflate at a 
slower rate than the front, or side airbags to 
afford greater protection from serious head 
injuries.

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 
Land Rover 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 fitment should be referred to your 
Land Rover Dealer/Authorised repairer as 
soon as possible for examination and repair.

Do not allow passengers 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 serious injury or death if objects 
or occupants are within the area of 
deployment.

AIRBAG WARNING LAMP

The airbag warning indicator is 
mounted in the instrument pack, 
and will illuminate as a bulb check 

when the ignition is turned on.

If any of the following warning indicator 
conditions occur, the vehicle should be 
checked by your Land Rover Dealer/Authorised 
repairer immediately.
• The warning indicator fails to illuminate 

when the ignition is turned on.

• The warning indicator fails to extinguish 

within six seconds of the ignition being 
turned on.

• The warning indicator illuminates at any 

time other than the bulb check, when the 
ignition is turned on.

WARNINGS

When an airbag inflates a fine powder 
is released. This is normal, and not an 
indication of a malfunction. However, 

the powder may cause irritation to the skin, 
and should be throughly flushed from 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 an explosive 
charge. Consequently airbag 

deployment is accompanied by a very loud 
noise which may cause discomfort and 
temporary loss of hearing.

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.
