SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
SRS ConfigurationINFOID:0000000001524154
The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in the ON or START posi-
tion.
The collision modes for which supplemental restraint systems are activated are different among the SRS sys-
tems. For example, the driver air bag module and front passenger air bag module are activated in a frontal col-
lision but not in a side collision.
SRS configurations which are activated for some collision modes are as follows:

System DescriptionINFOID:0000000001327432
DESCRIPTION
 Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
 Makes possible stable driving, with no wheel sp in, on snowy roads or other slippery surfaces.
 On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close to
rear-wheel drive.
 Sensor inputs determine the vehicle's turning conditi on, and in response tight cornering/braking are con-
trolled by distributing optimum torque to front wheels.
NOTE:
 When driving, if there is a large difference between front and rear wheel speed which continues for a long
time, fluid temperature of drive system parts becom es too high and AWD warning lamp flashes rapidly.
(When AWD warning lamp flashes, vehicle changes to r ear-wheel drive conditions.) Also, optional distribu-
tion of torque sometimes becomes rigid before lamp flashes rapidly, but it is not malfunction.
 If AWD warning lamp is flashing rapidly, stop vehicle and allow it to idle for some time. Flashing will stop and AWD system will be restored.
 When driving, AWD warning lamp may flash slowly if ther e is a significant difference in diameter of the tires.
At this time, vehicle performance is not fully avail able and cautious driving is required. (Continues until
engine is turned OFF.)
 If the warning lamp flashes slowly during driving but remains OFF after engine is restarted, the system is
normal. If it again flashes slowly after driving for some time, vehicle must be inspected.
 When the difference of revolution speed between the front and rear wheel mode the shift occasionally
changes to direct 4-wheel driving conditions automatically. This is not malfunction.
