The selected shift range, from S1 to S6, will be displayed in the meter.
The initial shift range in S mode is auto-
matically set to S2, S3, S4 or S5 according to the vehicle speed.
■Shift ranges and their functions
●You can choose from 6 levels of acce lerating force and engine braking
force.
●A lower shift range will provide gr eater accelerating force and engine
braking force than a higher shift rang e, and the engine revolutions will also
increase.
●If you accelerate while in ranges 1 to 4, the shift range may automatically
increase in accordance with the vehicle speed.

tires slip due to sudden acceleration.
ASC (Active Sound Control)
: If equipped
The ASC system is an electronic soun d system that generates driving sound,
conveying the kinetic situations of the vehicle’s acceleration and deceleration
to the driver through the speakers behi nd the instrument panel. The vehicle’s
response to the driver’s acceleration behavior and shift operations are also
conveyed in sound. When sport mode is selected, the sound conveyed to the
driver will be louder.

■The windshield wiper and washer can be operated when
The power switch is in ON mode.
■Dripping prevention wiper sweep
After performing a washing and wiping operat ion several times, the wipers operate one
more time after a short delay to prevent dripping.
However, this final wiper operation will not be performed while driving.
■Effects of vehicle speed on wiper operation (vehicles with rain-sensing windshield wip-
ers)
Vehicle speed affects the following even when the wipers are not in AUTO mode.
●Intermittent wiper interval
●Wiper operation when the washer is being used (delay until drip prevention wiper
sweep occurs)
With low speed windshield wiper operation selected, wiper operation will be switched
from low speed to intermitte nt wiper operation only when the vehicle is stationary.
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper is turned to AUTO mode while the power switch is in ON mode, the wipers
will operate once to show th at AUTO mode is activated.
●If the temperature of the raindrop sensor is 85°C (185°F) or higher, or -30°C (-22°F)
or lower, automatic operation may not occur. In this case, operate the wipers in any
mode other than AUTO mode.
■When the windshield wipers are in tempor ary operation (vehicles with rain-sensing
windshield wipers)
AUTO mode cannot be activated even if is pressed.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield
washer fluid reservoir.
●The raindrop sensor judges the amount of
raindrops.
An optical sensor is ad opted. It may not oper-
ate properly when sunlight from the rising or
setting of the sun inte rmittently strikes the windshield, or if bugs etc. are present on the
windshield.

●Side road speed signs may be detected and displayed (if positioned in sight of the cam-
era sensor) while the vehicle is traveling on the main road.
●Roundabout exit road speed signs may be detected and displayed (if positioned in sight
of the camera sensor) while traveling on a roundabout.
■When driving vehicle in country with different speed unit
Since RSA recognizes signs based on the set un it of the meter, it is necessary to change
the set unit of the meter. Adjust the set unit of the meter to the speed unit of signs in the
current location. ( P. 657)
■Turning the system on/off
■Speed limit sign display
If the power switch was last turned off while a speed limit sign was displayed on the multi- information display, the same sign displays again when the power switch is turned to ON
