■Running out of fuel
When the vehicle has run out of fuel and the
hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to
make the low fuel level warning light
(  P.351) go off. If th ere is only a small
amount of fuel, the hybrid system may not
be able to start. (The standard amount of fuel is about 3.3 gal. [12.6 L, 2.8 Imp.gal.],
when the vehicle is on a level surface. This
value may vary when the vehicle is on a
slope. Add extra fuel when the vehicle is
inclined.)
■Electromagnetic waves
●High voltage parts and cables on hybrid
vehicles incorporate electromagnetic
Hybrid system precautions (LC500h)
Take care when handling the hybrid system,
as it is a high voltage system (about
650 V at maximum) as well as contains parts that become extremely hot when
the hybrid system is operating. Obey th e warning labels attached to the vehi-
cle.

●In the following situations, if the situation has changed (or the vehicle has been driven for
some time) and the normal operating conditions are detected, the message will disappear
and the system will become operational.
If the message does not disappea r, contact your Lexus dealer.
• When the temperature around the radar sensor is outside of the operational range, such as when the vehicle is in the sun or in an extremely cold environment
• When the front camera cannot detect objects in front of the vehicle, such as when driving
in the dark, snow, or fog, or when brig ht lights are shining into the front camera
When the temperature around the front
camera is outside of th e operational range,
such as when the vehicle is in the sun or in an
extremely cold environment
If the front camera is hot, such as after the
vehicle had been parked in the sun, use the
air conditioning system to decrease the tem-
perature around the front camera.
If a sunshade was used when the vehicle was
parked, depending on its type, the sunlight
reflected from the surface of the sunshade
may cause the temperature of the front cam-
era to become excessively high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold envi-
ronment, use the air conditioning system to
increase the temperature around the front
camera.
The area in front of the front camera is
obstructed, such as when the hood is open
or a sticker is attached to the part of the
windshield in front of the front camera.
Close the hood, remove the sticker, etc. to
clear the obstruction.

excess of 6 mph (10 km/h).
●The sensors’ detection areas and reac-
tion times are limited. When moving
forward or reversing, check the areas
surrounding the vehicle (especially the
sides of the vehicle) for safety, and
drive slowly, using the brake to control
the vehicle’s speed.
●Do not install accessories within the
sensors’ detection areas.
NOTICE

may not function correctly due to a sen-
sor malfunction etc. Have the vehicle
checked by your Lexus dealer.
●The intuitive parking assist operation
display flashes or shows continuously,
and a beep sounds when no obstacles
