gradually decrease?
Even if the SPORT
indicator light
blinks, the system
is in normal condi-
tion. A temporary

wheels may light the ABS warning light, but this
indicates no malfunction. When AT control di-
agnosis is finished, perform the VDC memory
clearance procedure of on-board diagnostics
system.
