4-5. Using the driving support systems
When the system judges that the vehicle is deviating from the current
traffic lane, an alert buzzer sounds and it prompts cautions from the
display screen of the multi-information display.
When the alert buzzer sounds, please check the surrounding road situa-
tion and return near the center of the white (yellow) lane markers by safely
operating the steering wheel.
Press the LDA switch to activate
the LDA.
LDA indicator will come on and
lane lines will be displayed on the
multi-information display.
Press the switch again to deacti-
vate the LDA.
The LDA will remain on or off even
if the power switch is turned off.

Driving
■LDA indicator
Even if the LDA switch is pressed, when the LDA indicator does not come on
the system may have a malfunction. Have the vehicle inspected by your Toy-
ota dealer immediately.
■Alert buzzer for lane departure alert
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 alert buzzer.
■After the vehicle has been parked in the sun
The LDA may not be available and a warning message will be displayed for a
while after driving has started. When the temperature in the cabin decreases
and the temperature around the camera sensor (P. 227) becomes suitable
for its operation, turn the LDA switch on again after a short time.
■If there are lane markers on only one side of the vehicle
The lane departure alert will not operate for 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 alert function to operate incorrectly.
However, this does not indicate a malfunction.
●When there are shadows on the road running parallel with lane markers, or
if a shadow covers the lane markers
●When driving through an area with no lane markers, such as a toll booth, a
crossing or before a ticket checkpoint
●When the lane markers are broken, Botts’ dots (raised pavement markers)
or stones
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When driving on a road surface that is wet due to rain, previous rainfall,
standing water, etc.
●When the lane markers are yellow (These may be more difficult for the sys-
tem to recognize compared to white markers.)
●When the lane markers are on a curb, etc.
●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
●When sunlight or the headlights of oncoming vehicles are shining directly
into the camera lens
●When driving on roads that are branching or merging
●When driving on winding roads or roads that are uneven

4-5. Using the driving support systems
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the hybrid system
off. The EPS system should return to normal within 10 minutes.
■Automatic reactivation of TRAC system
After turning the TRAC system off, the system will be automatically re-
enabled in the following situations:
●When the power switch is turned off
●The TRAC will turn on when vehicle speed increases
■Electric power steering system warning light (warning buzzer)
P. 491
■Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:
●The shift position is in a position other than P or N (when starting off forward/
backward on an upward incline).
●The vehicle is stopped.
●The accelerator pedal is not depressed.
●The parking brake is not engaged.
■Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
●Shift the shift position to P or N.
●The accelerator pedal is depressed.
●The parking brake is engaged.
●Approximately 2 seconds elapse after the brake pedal is released.

PCS (Pre-Collision System)
◆Pre-collision warning
When a high possibility of a frontal
collision is detected, a buzzer
sounds and a message is shown
on the multi-information display to
urge the driver to take evasive
action.
◆Pre-collision brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is
depressed.
◆Pre-collision braking
When there is a high possibility of a frontal collision, the system warns the
driver using a warning display and buzzer. If the system determines that a
collision is unavoidable, the brakes are automatically applied to reduce the
collision speed.
: If equipped
When the radar sensor detects possibility of a frontal collision,
brakes are automatically engaged to lessen impact as well as
vehicle damage.
The alert timing for the pre-collision system can be changed or
turned ON/OFF, as necessary, by operating the switch. (P. 254)
