Safety systems
The information "while the engine is running" given in the vehicle Operator's Manual regarding the
signaling behavior of a warning/indicator lamp corresponds to the READY driving status. When a
warning/indicator lamp lights up in the READY driving status with the corresponding information,
the causes/consequences and solutions given in the vehicle Operator's Manual also apply to your
vehicle.
