■Fuel types
 P.357
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehi-
cle has a fuel tank opening that only accom-
modates the special nozzle on unleaded
fuel pumps.
■If the malfunction indicator lamp illumi-
nates
The malfunction indicator lamp may illumi-
nate erroneously if refueling is performed

WARNING
■When refueling the vehicle
Observe the following precautions while
refueling the vehicle. Failure to do so
may result in death or serious injury.
●After exiting the vehicle and before
opening the fuel door, touch an
unpainted metal surface to discharge
any static electricity. It is important to
discharge static electricity before refu-
eling because sparks resulting from
static electricity can cause fuel vapors
to ignite while refueling.
●Always hold the grips on the fuel tank
cap and turn it slowly to remove it.
A whooshing sound may be heard
when the fuel tank cap is loosened.
Wait until the sound cannot be heard
before fully removing the cap. In hot
weather, pressurized fuel may spray
out the filler neck and cause injury.
●Do not allow anyone that has not dis-
charged static electricity from their
body to come close to an open fuel
tank.
●Do not inhale vaporized fuel.
Fuel contains substances that are
harmful if inhaled.
●Do not smoke while refueling the vehi-
cle.
Doing so may cause the fuel to ignite
and cause a fire.
●Do not return to the vehicle or touch
any person or object that is statically
charged.
This may cause static electricity to
build up, resulting in a possible ignition
hazard.
■When refueling
Observe the following precautions to
prevent fuel overflowing from the fuel
tank:
●Securely insert the fuel nozzle into the
fuel filler neck.
●Stop filling the tank after the fuel noz-
zle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such
as causing the emission control system to
operate abnormally or damaging fuel
system components or the vehicle’s
painted surface.

WARNING
■When replacing the fuel tank cap
Do not use anything but a genuine Lexus
fuel tank cap designed for your vehicle.
Doing so may cause a fire or other inci-
dent which may result in death or serious
injury.

1784-5. Using the driving support systems
●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 disap-
pear and the system will become operational.
If the message does not disappear, 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.

4-6.Driving tips
Use fluids that are appropriate to
the prevailing outside temperatures.
• Engine oil
• Engine coolant
• Washer fluid
Have a service technician inspect
the condition of the battery.
 Have the vehicle fitted with four
snow tires.
Ensure that all tires are the specified size
and the same brand.
Perform the following according to the
driving conditions:
Do not try to forcibly open a door or
a side window, or move wipers that
are frozen. Pour warm water over
the frozen area to melt the ice, and
then wipe away the water immedi-
ately to prevent it from freezing.
 When the outside door handle is
frozen, unlock the doors using the
wireless remote control. If the out-
side door handles remain retracted
and do not move even if the doors
are unlocked using the wireless
remote control, pour warm water
over the frozen area to melt the ice
and wipe away the water immedi-
ately to prevent it from freezing. The
outside door handle may not retract
due to ice, however, the outside
door handle will return to the nor-
mal position after the ice melts.
 To ensure proper operation of the
climate control system fan, remove
Winter driving tips
Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.
Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air
pressure.
●Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
●Use snow tires on all, not just some
wheels.
NOTICE
■Driving with tire chains
Do not fit tire chains. Tire chains may
damage the vehicle body and suspen-
sion, and adversely affect driving perfor-
mance.
■Repairing or replacing snow tires
Request repairs or replacement of snow
tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attach-
ment of snow tires affects the operation
of the tire pressure warning valves and
transmitters.
