Rear impacts

If the seat belt pre-tensioners are deployed during a 
rear impact, the following components must be 
replaced:

l

Seat belt pre-tensioners.

l

SRS DCU.

l

Front and rear seat belt retractors used during 
impact.

In addition, the following components should be 
inspected for damage and replaced as necessary:

l

Front seat frames and head restraints

l

Seat belt height adjusters

l

Front seat belts, retractors, webbing, tongue 
latching, 'D' loop and body anchorage points

l

Rear seat belt buckles, webbing, buckle covers, 
tongue latching, and body anchorage points

l

SRS side impact sensor.

Periodic replacement of SRS components

The performance of the propellants within airbags 
and pre-tensioners will deteriorate over a period of 
time. 

As a result, it is essential that airbags, seat belt 
pre-tensioners and the rotary coupler are 
replaced every 15 years.

Air Conditioning System Precautions

General
The air conditioning system contains fluids and 
components which could be potentially hazardous to 
the service engineer or the environment if not 
serviced and handled correctly. The following 
guidelines are intended to alert the service engineer 
to potential sources of danger and emphasise the 
importance of ensuring the integrity of the Air 
Conditioning operating conditions and components 
fitted to the vehicle.

Where necessary, additional specific precautions are 
detailed in the relevant sections of this Manual which 
should be referred to prior to commencing repair 
operations.

The refrigerant used in the air conditioning system is 
HFC-134a (Hydrofluorocarbon) R134a.

WARNING: Servicing must only be carried out by 
personnel familiar with both the vehicle system 
and the charging and testing equipment. All 
operations must be carried out in a well 
ventilated area away from open flame and heat 
sources.

WARNING: R134a is a hazardous liquid and when 
handled incorrectly can cause serious injury. 
Suitable protective clothing, consisting of face 
protection, heat proof gloves, rubber boots and 
rubber apron or waterproof overalls, must be 
worn when carrying out operations on the air 
conditioning system.
