WARNING
■If a safety system warning light does
not come on
Should a safety system light such as the
ABS and SRS warning light not come on
when you start the hybrid system, this
could mean that these systems are not
available to help protect you in an acci-
dent, which could result in death or seri-
ous injury. Have the vehicle inspected by
your Lexus dealer immediately if this
occurs.

WARNING
■Cautions regarding the use of the
function
The driver is solely responsible for safe
driving. Always driv e safely, taking care
to observe your surroundings.
The RCTA function is only a supplemen-
tary function which alerts the driver that a
vehicle is approaching from the right or
left at the rear of the vehicle. As the
RCTA function may not function cor-
rectly under certain conditions, the
driver’s own visual confirmation of safety
is necessary. Over reli ance on this func-
tion may lead to an accident resulting
death or serious injury.
