4485-4. Appearance Care
YARIS_YARIS HATCHBACK_OM_OM99V59z_(U)
Road chemicals and salt used for ice and snow removal and solvents
used for dust control may collect on the underbody. If not remo ved,
they will speed up rust ing and deterioration of such underbody parts
as fuel lines, frame, floor pan, and exhaust system, even though these
parts may be coated with anti-corrosive material.
Thoroughly flush the underbody and wheel housings with lukewarm or
cold water at the end of each wi nter. Try also to do this every month.
Pay special attention to these areas because they easily hide m ud
and dirt. It will do more harm than good to wet down the road grime
without removing it.
The lower edges of doors, rocker panels, and frame members have
drain holes that should not be clogged. Water trapped there wil l cause
rusting.
A protective coating is provided over the aluminum wheels. Spec ial
care is needed to protect this coating.
Underbody Maintenance
WARNING
■ Dry off brakes that have become wet by driving slowly, releasin g the
accelerator pedal and lightly applying the brakes several times until
the brake performance returns to normal
Driving with wet brakes is dangerous. Increased stopping distan ce or the
vehicle pulling to one side when braking could result in a seri ous accident.
Light braking will indicate whether the brakes have been affect ed.
