Do not use the LDA system in the following situations.
The system may not operate properly and lead to an accident, resulting in
death or serious injury.
●A spare tire, tire chains, etc. are equipped.
●When the tires have been excessively worn, or when the tire inflation pres-
sure is low.
●Tires which differ by structure, manufacturer, brand or tread pattern are
used.
●Objects or patterns that could be mistaken for white (yellow) lines are
present on the side of the road (guardrails, curbs, reflective poles, etc.).
●Vehicle is driven on a snow-covered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.

work.
●Vehicle is driven on a road surface which is slippery due to rainy weather,
fallen snow, freezing, etc.

2664-5. Using the driving support systems
This mode employs a radar sensor to detect the presence of vehicles
up to approximately 328 ft. (100 m) ahead, determines the current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on down-
hill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance switch.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+ RES” switch or depressing the accelerator pedal will resume follow-up
cruising.

formed, the tire pressure warn-
ing light will blink for
approximately 1 minute then
illuminate and “---” will be dis-
played for the inflation pres-
sure of each tire on the multi-
information display.
Drive straight (with occasional left and right turns) at approxi-
mately 25 mph (40 km/h) or more for approximately 10 to 30 min-
utes.
Registration is complete when the tire pressure warning light turns
