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 sys-
tem to recognize 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.

entrance to or exit from a tunnel
● When sunlight or the headlights of oncoming vehicles are shining directly
into the camera lens

standing water, etc.

or when the headlights are misaligned
● When driving on winding roads or roads that are uneven

Maintenance and care
■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. ( P. 438)
● If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.
■ If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
■ When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this
vehicle. Because certain bulbs are connected to circuits designed to prevent
overload, non-genuine parts or parts not designed for this vehicle may be
unusable.
WARNING
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.
●Never use a fuse of a higher amperage rating than that indicated, or use\
any other object in place of a fuse.
● Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
● Do not modify the fuses or fuse boxes.
■ Fuse box near the power control unit
Never check or replace the fuses as there are high voltage parts and wiring
near the fuse box.
Doing so may cause electric shock, resulting in death or serious injury.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by your
Toyota dealer as soon as possible.
