4-5. Using the driving support systems
■Temporary cancelation of the LDA system
When the lane departure warning function is activated. 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
It may be difficult to feel the sensory warning depending on the road conditions.
■After the vehicle has been parked in the sun
The LDA system may not be available and a warning message ( P. 771) will be dis-
played for a while after driving has started. When the temperature in the cabin
decreases and the temperature around the camera sensor ( P. 2 6 3 ) b e c o m e s s u i t -
able for its operation, the functions will begin to operate.
■Conditions in which the function may not operate correctly
In the following conditions, the LDA system may not operate, or it may not be possi-
ble to ensure adequate performance. Also, the camera sensor may be unable to rec-
ognize 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 may be more difficult for the system to
recognize compared to white markers.)
●When the lane markers are broken, “Botts’ dots”, “Raised pavement marker” or
stones
●When the lane markers are on a curb etc.
●When lane markers are obscured or pa rtially 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 particularly 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

4-6. Driving tips
Control your speed and keep at a constant speed. Also, before stopping
at a toll booth or similar, allow plenty of time to release the accelerator and
gently apply the brakes. A greater am ount of electrical energy can be
retained when slowing down.
Use the air conditioning only when ne cessary. Doing so can help control
excessive gasoline consumption.
In summer: In high temperatures, use th e recirculated air mode. Doing so
will help to reduce the burden on th e air conditioner and reduce fuel con-
sumption as well.
In winter: Because the gasoline engine will not automatically cut out until
the gasoline engine and the interior of the vehicle are warm, it will con-
sume fuel. Also, fuel consumption can be improved by avoiding overuse of
the heater.
Make sure to check the tire inflati on pressure frequently. Improper tire
inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large am ounts of friction, their use on dry
roads can lead to poor fuel consumptio n. Use a tire that is appropriate for
the season.
Carrying heavy luggage can lead to poor fuel consumption. Avoid carry-
ing unnecessary luggage. Installing a la rge roof rack can also cause poor
fuel consumption.
