01-12 INTRODUCTION - GENERAL RULES OF MAINTENANCE OPERATION

(i). Use the torque wrench with a longer handle.
• When using the special maintenance tool
or torque wrench with a longer handle,
if the torque indicated by the torque
reaches the specified value, it means
that the actual torque is too large.
• This manual only describes the torque
value needs to be specified. When using
the special maintenance tool or torque
wrench with a longer handle, please
calculate the torque according to the
following formula.

• Formula: T'=T×L2/(L1 ＋ L2)

2. Maintenance precautions for the vehicle type configured with the supplemental
restraint system
DANGER:
Part of vehicle types is configured with the supplemental restraint system: Driver airbag. In
case of operation not following the correct steps, it may cause sudden expansion of SRS,
and even result in serious accidents. At the same time, in case of wrong operation for
the supplemental restraint system, it may also lead to the failure to work properly. Before
carrying out the maintenance (including the removal, installation, inspection or replacement
of parts) for the supplemental restraint system, always carefully read all the following,
then carry out the operation following the correct steps as described in the maintenance
manual.
(a). General precautions.
• Because it is hard to identify the fault phenomenon for the supplemental restraint
system, diagnostic trouble code (DTC) will be taken as the most information
source when troubleshooting. Therefore, during troubleshooting for the
supplemental restraint system, always detect the diagnostic trouble code (DTC)
before disconnecting the battery.
