the following precautions is recommended:
●
For the first 186 miles (300 km):
Avoid sudden stops.
●
For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for
extended periods.
■
Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type park- ing brake system. This type of brake system
needs bedding-down of the brake shoes
periodically or whenever the parking brake
shoes and/or drum are replaced. Have your
Lexus dealer perform the bedding down
operation. ■
Brake pads and discs (F SPORT models)
The brake pads and discs are designed for
use under high load conditions. Therefore,
brake noise may be generated depending
on the vehicle speed, braking force and
vehicle environment (temperature, humid-
ity, etc.). ■
Operating your vehicle in a foreign
country
Comply with the relevant vehicle registra-
tion laws and confirm the availability of the
correct fuel. (  P.447)■
Idling time before engine stop
To prevent damage to the turbocharger,
allow the engine to idle immediately after
high-speed driving or hill climbing.

Fuel types
 P.455■
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.Opening the fuel tank cap Perform the following steps to open
the fuel tank cap:
Before refueling the vehicle
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 ve hicle 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.

dent which may result in death or serious
injury.

3155-3. Using the air conditio ning system and defogger
LS500_OM_(U)_1810 5
Interior features ●
When the engine switch is turned off, the
current air conditioning settings will auto-
matically be registered to the electronic
key that was used to unlock the vehicle.●
The system may not operate correctly if
more than one electr onic key is in the
vicinity or if the smart access system with
push-button start is used to unlock a pas-
senger door.●
The doors that can recall the air condi-
tioning setting *
when unlocked using the
smart access system with push-button
start can be changed. For details, contact
your Lexus dealer. *
: The doors that can recall the driving
position memory are changed at the
same time.■
Operation of the air conditioning sys-
tem in Eco drive mode
In Eco drive mode, the air conditioning sys-
tem is controlled as follows to prioritize fuel
efficiency: ●
Engine speed and compressor operation
controlled to restri ct heating/cooling
capacity●
Fan speed restricted when automatic
mode is selected
To improve air condit ioning performance,
perform the following operations: ●
Turn off eco air conditioning mode
(  P.316) ●
Adjust the fan speed●
Turn off Eco drive mode (  P.289)
■
When the outside temperature falls to
nearly 32°F (0°C)
The dehumidification function may not
operate even when “A/C” is selected.
■
Ventilation and air conditioning odors
●
To let fresh air in, set the air conditioning
system to the outside air mode.
●
During use, various odors from inside and
outside the vehicle may enter into and
accumulate in the air conditioning sys-
tem. This may then cause odor to be
emitted from the vents.
●
To reduce potential odors from occur- ring:
• It is recommended that the air condition-
ing system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be
delayed for a short pe riod of time imme-
diately after the air conditioning system is
started in automatic mode or with the
micro dust and pollen filter on. ●
When parking, the system automatically
switches to outside air mode to encour-
age better air circulation throughout the
vehicle, helping to reduce odors that
occur when starting the vehicle. ■
Using the voice command system
Air conditioning system can be operated
using voice commands. For details, refer to
the “NAVIGATION AND MULTIMEDIA
SYSTEM OWNER’S MANUAL”. ■

WARNING■
To prevent the windshield from fog-
ging up
Do not use the windshield defogger
switch during cool air operation in
extremely humid weather. The difference
between the temperature of the outside
air and that of the windshield can cause
the outer surface of the windshield to fog
up, blocking your vision.
■
When the outside rear view mirror
defoggers are operating
Do not touch the outside rear view mir-
ror surfaces, as they can become very
hot and burn you.
