WARNING: All SRS system components must be replaced after 15 years of operation.

Warning:If the vehicle is equipped with a front passenger airbag, it is forbidden to install a child safety seat in the front seat that is designed to transport children facing the rear of the vehicle.

General warnings

The SRS system contains components that, if improperly handled, present a hazard to service personnel. The following instructions are intended to familiarize service personnel with the hazards of the SRS system and to demonstrate the consequences of improper handling of the SRS system.

WARNING: Always follow the SRS operating procedures and the recommended maintenance and repair procedures. Personnel authorized to work on the SRS system must have received special training and have copies of the SRS operating procedures.

WARNING: Do not perform any work on the SRS system until you have read the relevant sections of this Manual.

WARNING: Air bags contain flammable and hazardous substances. Any contact with water, acids or heavy metals may cause an explosion or other harmful effects. Do not disassemble, burn or expose non-activated air bags to electricity.

WARNING: A seat belt that has been subjected to a critical load during a collision or shows signs of damage must be replaced with a new one.

WARNING: Before performing welding on a vehicle equipped with the SRS system, the battery must be disconnected.

CAUTION: Do not expose air bags or seat belt pretensioners to temperatures above 85°C (185°F).

Please note that the instructions provided should not only be followed during direct repair of the SRS system. The same safety precautions should be observed when working on associated systems and components located in close proximity to the SRS system components. The following systems and components are not a complete list of such systems and components:

• Steering - Driver's front airbag, rotary switch
• Control Panel - Front Passenger Airbag
• Interior trim - Side curtain airbags
• Seats - Front seat belt pretensioners
• Electrical Equipment - SRS Wiring Harnesses, Connecting Wires and Connectors
• Front Doors - Side Airbags

How to deactivate the SRS system

Before working on or near the SRS components, the system must be deactivated.

To do this, follow these steps.

• Remove the key from the ignition switch
• Disconnect the battery. The ground wire is disconnected first.
• Wait for 10 minutes. During this time, the SRS power source is discharged.

The SRS system is powered by batteries, which ensure that the system is activated in the event of damage to the electrical supply system during an accident. Sufficient time (10 minutes) must pass for the batteries to fully discharge. This will eliminate the possibility of accidental activation of the system.

Installing SRS system components

To ensure reliable operation of the SRS system, periodic inspection and maintenance are required. All SRS components must be carefully inspected before installation. Do not install components that show signs of rough handling, such as dents, cracks, or residual deformation.

WARNING: The reliability of the SRS system directly affects the passive safety of the vehicle. Strictly adhere to the following rules.

WARNING: Do not use interior trims that cover air bags (such as A-pillar trims) to secure accessories or for other purposes.

• Do not install used SRS components.; do not attempt to repair SRS system components.
• When repairing the SRS system, use only genuine spare parts.
• Do not apply voltage to the terminals of SRS components unless instructed to do so.
• Special fasteners are used to secure the airbags - strictly observe the tightening torques. It is prohibited to use other fasteners.
• When replacing SRS system components, replace the fasteners with new ones.
• When replacing the SRS electronic unit (DCU), make sure it is installed correctly. There should be no gap between the electronic unit (DCU) and its mounting bracket. Incorrect installation of the SRS electronic unit (DCU) may cause the system to malfunction.

CAUTION: When installing the side curtain airbag, make sure that its fasteners are securely fastened and do not interfere with the airbag deployment. When installing the A-pillar trim and the roof trim, make sure that they do not interfere with the airbag deployment.

CAUTION: SRS system components must be free of oil, grease, cleaning agents or water.

CAUTION: Torque wrenches should be checked regularly to ensure that all fasteners are properly tightened.

NOTE: After the seat belt pretensioners have deployed, the seat belts may be used as normal seat belts without pretensioners. In this case, replace the belts as soon as possible to restore the SRS system to its designed function.

NOTE: If replacement of SRS components is required, the part number and bar code of the new part must be recorded.

Precautions when checking SRS system components

Airbags deploy at relatively low current levels, so always follow these instructions:

WARNING: When checking SRS components, do not use multimeters or other multi-purpose equipment - this may cause the airbags to deploy. Use only the special diagnostic tool Testbook/T4 to diagnose the system.

WARNING: Do not use multi-purpose diagnostic equipment to troubleshoot SRS harnesses that are not disconnected from the system components, as this may result in airbag deployment and injury.

Transportation and storage

When handling SRS system components, follow the instructions below.

WARNING: Supplementary storage requirements for SRS components may be required. This may require approval from local authorities. SRS components require careful handling and present an increased risk if handling and storage instructions are not followed. Always follow these instructions:

• Do not throw SRS components. The SRS electronic unit requires particularly careful handling. The airbags and seat belt pretensioners may deploy in the event of a severe impact.
• Do not wrap your hands around the airbags. When transporting airbags, hold them by the cover, with the cover in the highest position and the base facing away from your body.
• Do not transport airbags or seat belt pretensioners in the passenger compartment of the vehicle. When transporting in a vehicle, place airbags and seat belt pretensioners in the trunk.
