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. ●

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. ■

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

RC F_U WARNING ■
Caution for use while driving ●
When operating the multi-information display while driving, pay extra attention to the
safety of the area around the vehicle. ●
Do not look continuously at the multi-info rmation display while dr iving as you may fail
to see pedestrians, objects on the road, etc. ahead of the vehicle. ■
The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal information
display. At extremely low temperatures, th e information display monitor may respond
slowly, and display changes may be delayed.
For example, there is a lag between the dr iver’s shifting and the new gear number
appearing on the display. This lag could ca use the driver to downshift again, causing
rapid and excessive engine braking and possibly an accident resulting in death or
injury. ■
Cautions during setting up the display
As the engine needs to be running during sett ing up the display, en sure that the vehicle
is parked in a place with adequate ventilation. In a closed area such as a garage,
exhaust gases including harmful carbon mo noxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.
NOTICE ■
While setting up the display
To prevent battery discharge, ensure that the engine is running while setting up the dis-
play features.
