- *3: with Intelligent AFS
- When the engine switch on (IG) while driving at 3 mph (5 km/h) or less, the switch except for SONAR can be displayed.
- The switch functions displayed are changed in the order shown in the illustration using the satellite switch (RH switch, LH switch). The function can be set using the ON/OFF switch.
- The display automatically returns to the previous display 6 seconds after the satellite switch is operated. It will return to the previous display immediately if the DISP switch is operated.

SPEED and TACH indicator

The SPEED indicator and TACH indicator come on when the vehicle speed or engine speed reaches the speed set using the satellite switch. The setting ranges of these indicators are shown in the table that follows.
Vehicle speed or engine speed can be set using the satellite switch.
These indicators consist of yellow and red dots that are arranged to form indicator rings.
When the set vehicle speed or engine speed is reached while driving, the red and yellow dots will turn on at the same time to cause amber light to illuminate the indicator ring.
However, if the vehicle or engine speed is set to the maximum speed of the indicator setting range, and the speed reaches this set speed, only red light will illuminate the indicator ring.
