For safety and security WARNING■
When the Pop Up Hood is operated●
Do not pull the hood lock release lever.
Doing so after the Pop Up Hood has
operated will further raise the hood
and may cause an injury. Do not drive
with the hood raised, as doing so may
block the driver’s vision, possibly caus-
ing an accident.●
Do not forcibly push down the hood.
As the popped up hood cannot be
lowered by hand, doing so may deform
the hood or cause an injury.●
If the Pop Up Hood has operated, have
it replaced by your Lexus dealer. If the
Pop Up Hood has operated, stop the
vehicle in a safe place and contact
your Lexus dealer.●
Do not touch the lifters immediately
after the Pop Up Hood has operated,
as the lifters may be hot and burn you.
NOTICE■
Pop Up Hood precautions●
Make sure to close the hood before
driving, as the system may not operate
properly if the hood is not fully closed.
●
Make sure that all 4 tires are of the
specified size and inflated to the speci-
fied tire pressure. If tires of a different
size are used, the system may not
operate properly.
●
If something has hit the area around
the front bumper, the sensors may be
damaged even if the Pop Up Hood has
not operated. Have the vehicle
inspected by your Lexus dealer.
●
Do not remove or repair the parts or
wiring of the Pop Up Hood, as doing
so may cause accidental operation or
prevent the system from operating
properly. If repair or replacement is
necessary, contact your Lexus dealer. ●
Do not remove such components as
the front bumper, hood or suspension,
or replace them with non-genuine
parts, as doing so may prevent the sys-
tem from operating properly. ●
Do not install anything to the front
bumper or hood, as doing so may pre-
vent the sensors fr om detecting an
impact correctly and prevent the sys-
tem from operating properly. ●
Do not close the hood with force or
apply load to the lifters, as doing so
may damage the lifters and prevent the
system from operating properly. ●
Do not modify the suspension, as
changes made to the vehicle height
may prevent the system from operat-
ing properly.
