■Suspension of the settings display
In the following situations, operation of th e settings display 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 temperature. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.
■When disconnecting and reconnecting 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

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 driving 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 cau se the driver to downshift again, causing
rapid and excessive engine braking and po ssibly an accident resulting in death or injury.
■Cautions during setting up the display
As the engine needs to be running during setting up the display, ensure that the vehicle is parked in a place with adequate ventilation. In a closed area such as a garage,exhaust gases including harmful carbon monoxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.

■Temporary cancelation of the LDA system functions
If any of the following occurs, the LDA system functions will be temporarily canceled. The functions will resume after the necessary operating conditions have returned.
●The turn signal lever is operated.
●The vehicle speed deviates from the operating range of the LDA system functions.
●When the lane lines cannot be recognized while driving.
●When the lane departure warning sounds.
The lane departure warning function will not operate again for a several seconds after it has been activated, even if the vehicle leaves the lane again.
■The lane departure warning
Depending on the audio system sound level or air conditioning fan noise while the audio system or air conditioning system is in use, it may be difficult to hear the warning sound.
■After the vehicle has been parked in the sun
The LDA system may not be available and a warning message ( P. 603) will be dis- played for a while after driving has started. When the temperature in the cabin decreasesand the temperature around the camera sensor ( P. 314) becomes suitable for its oper-
ation, the functions will begin to operate.
■If there are lane markers on only one side of the vehicle
The lane departure warning will not operate fo r the side on which lane markers could not
be recognized.
■Conditions in which the function may not operate correctly
In the following situations, the camera sensor may be unable to recognize lane markers
causing the lane departure warning function to operate incorrectly. However, this does not indicate a malfunction.
●When driving through an area with no lane markers, such as a tollbooth, a crossing or
before a ticket checkpoint
●When driving on a sharp curve
●When lane markers are extremely narrow or extremely wide
●When the vehicle leans to one side an unusual amount due to a heavy load or improper tire inflation pressure
●When the following distance between your vehicle and the vehicle ahead is extremely
short
●When the lane markers are yellow (These ma y be more difficult for the system to rec- ognize compared to white markers.)
●When the lane markers are broken, Botts’ dots (raised pavement markers) or stones
●When the lane markers are on a curb etc.
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When there are shadows on the road running parallel with lane markers, or if a shadow covers the lane markers
●When driving on a partic ularly bright road surface, such as concrete
●When driving on a road surface that is bright due to reflected light
●When driving in a location where the light level changes rapidly, such as the entrance to
or exit from a tunnel
