intermittent wiper operation when
the vehicle is stationary. (However,
when the sensor s ensitivity is
adjusted to the highest level, the
mode will not switch.)
■Raindrop sensor (vehicles with
rain-sensing windshield wipers)
●The raindrop sensor judges the
amount of raindrops.
●If the wiper switch is turned to the
“AUTO” position while the engine
switch is in ON, the wipers will
operate once to show that “AUTO”
mode is activated.
●If the wiper sensitivity is adjusted
to higher, the wip er may operate
once to indicate the change of
sensitivity.

sensor is 185°F (85°C) or higher,
or 5°F (-15°C) or lower, the auto-
matic operation m ay not occur. In

versa, operation sounds and vibra-
tions may be generated, but this is
not a malfunction.
■EPS operation sound
When the steering wheel is oper-
ated, a motor sou nd (whirring
sound) may be heard. This does not
indicate a malfunction.

off.
●If only the TRAC system is turned
off, the TRAC will turn on when

cle speed increases.
■Operating conditions of Active
Cornering Assist

lowing occurs.
●TRAC/VSC can operate
●The driver is at tempting to accel-
erate while turning
●The system detects that the vehi-
cle is drifting to the outer side
●The brake pedal is released
■Reduced effectiveness of the
EPS system
The effect iveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period of time. The steer-
ing wheel may feel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle and turn the engine
off. The EPS syste m should return
to normal within 10 minutes.
