■Pop Up Hood operational conditions
The Pop Up Hood will operate when the
vehicle detects an impact such as the fol-
lowing:
●The front bumper detects a frontal
impact equivalent to or greater than that
of a pedestrian while the vehicle being
driven within the operational speed
range of approximately 16 to 34 mph (25
to 55 km/h). (The system is operated by
an impact of threshold level or greater,
even in the case of a minor collision that
may not leave a trace on the front
bumper. Also, depending on the impact
conditions or vehicle speed, the system
may operate by a collision with a light or
small object or a small animal.)
●In other situations such as the following,
the system may operate when an impact
is applied to the lowe r part of the vehicle
or front bumper:
• Colliding with a curb
• Falling into a deep hole
• Landing hard
• Hitting the slope of a parking lot, an undulating road, a protruding object or
falling object
■Conditions under which the Pop Up
Hood may not operate properly
●If a pedestrian collides with the right or
left corner of the front bumper or the side
of the vehicle. As such impacts may be
difficult to detect, the system may not
operate.
●If the vehicle speed is not detected cor-
rectly, such as if the vehicle is sliding side-
ways, the system may not operate
properly.
■Conditions under which the Pop Up
Hood will not operate
The Pop Up Hood will not operate in the
following situations:
●Colliding with a lying person
●A frontal impact applied to the front
bumper while driving at speeds outside
of the operational speed range
●A side impact or rear impact
●A vehicle rollover (In some accident situ-
ations, the Pop Up Hood may operate.)
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
causing 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.

2626-1. Maintenance and care
Remove dirt and dust using a vac-
uum cleaner. Wipe dirty surfaces
with a cloth dampened with luke-
warm water.
 If dirt cannot be removed, wipe it off
with a soft cloth dampened with
neutral detergent diluted to approx-
imately 1%.
Wring out any excess water from
the cloth and thoroughly wipe off
remaining traces of detergent and
water.
Small dirt such as dust
Use a compressed air blow gun to
remove dust.
Severe dirt such as a stain
Dampen a small amount of water in a
cloth similar in material and color to
the soft top roof fiber, and wipe off the
dirt. And then allow the soft top roof to
dry in a shaded and ventilated area.
■Shampooing the carpets
There are several commercial foaming-
type cleaners available. Use a sponge or
brush to apply the foam. Rub in overlapping
circles. Do not use water. Wipe dirty sur-
faces and let them dry. Excellent results are
obtained by keeping the carpet as dry as
possible.
■Handling the seat belts
Clean with mild soap and lukewarm water
using a cloth or sponge. Also check the
belts periodically for excessive wear, fray-
ing or cuts.
■When cleaning the carpeted portions of
the glove box, console box, etc.
If a strong adhesive ta pe is used, there is a
possibility that the surface of the carpet
could be damaged.
■CFRP (Carbon Fiber Reinforced Plas-
tic) parts (if equipped)
CFRP is used for the scuff plates. When
cleaning the scuff plates, remove dirt using
a water-dampened soft cloth or synthetic
chamois, and then wipe the surface with a
dry soft cloth to remove any remaining
moisture.
Cleaning and protecting the
v
ehicle interior
Perform cleaning in a manner
appropriate to each component
and its material.
