G-force display ●
The G-force values may not be zero even when the vehicle is parked, such as when it is
parked on an incline. ●
The steering amount, accelerator pedal input, and brake fluid pressure displays are dis-
abled until the engine has warmed up (the variable red zone of the tachometer has
retracted to 7300 rpm).
After the engine has warmed up, these displays will be enabled. ●
Depending on the vehicle usage conditions, the brake fluid pressure display may not
reach its maximum reading even though the brake pedal is fully depressed. ●
If a battery terminal is disconnected and reconnected, the steering amount display may
be disabled temporarily. Afte r driving the vehicle for a while , the display will be enabled.■
Suspension of the settings display
In the following situations, op eration of the settings disp lay will be temporarily sus-
pended. ●
When a warning message appears on the multi-information display●
When the vehicle begins to move ■
Tire pressure ●
It may take a few minutes to display the tire inflation pressure after the engine switch is
turned to IGNITION ON mode. It may also take a few minutes to display the tire infla-
tion pressure after inflation pressure has been adjusted.●
“---” may be displayed if the tire position information cannot be determined due to
unfavorable radio wave conditions. ●
Tire inflation pressure changes with temperat ure. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge. ■
When disconnecting and reco nnecting battery terminals
The following information data will be reset: ●
Drive information ●
Lap timer: Measured lap times, history ●
G-force: Record of the maximum G-forces■
Using the lap timer
If the engine is stopped while a lap is being timed, the lap timer will stop and the lap time
up to that point will be recorded. ■
Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is characteristic
of liquid crystal displays, and there is no problem continuing to use the display.
