slope. Add extra fuel when the vehicle is
inclined.)

WARNING
■If a safety system warning light does
not come on
Should a safety system light such as the

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.
