Driving
Control and maintain the vehicle at a
constant speed. Before stopping at a
toll booth or similar, allow plenty of
time to release the accelerator and
gently apply the brakes. A greater
amount of electrical energy can be
regenerated when slowing down.
Use the air conditioning only when
necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient tem-
perature is high, use the recirculated
air mode. Doing so will help to reduce
the burden on the air conditioning sys-
tem and reduce fuel consumption as
well.
In winter: Because the gasoline engine
will not automatically cut out until it and
the interior of the vehicle are warm, it
will consume fuel. Also, fuel consump-
tion can be improved by avoiding over-
use of the heater.
Make sure to check the tire inflation
pressure frequently. Improper tire infla-
tion pressure can cause poor fuel
economy.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to poor fuel economy.
Use tires that are appropriate for the
season. Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage.
Installing a large
roof rack will also cause poor fuel
economy.
Since the gasoline engine starts up and
cuts out automatically when cold,
warming up the engine is unnecessary.
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess
fuel consumption.

■When the outside temperature exceeds
75°F (24°C) and the air conditioning
system is on
●In order to reduce the air conditioning
power consumption, the air conditioning
system may switch to recirculated air
mode automatically.
This may also reduce fuel consumption.
●Recirculated air mode is selected as a
default mode when the power switch is
turned to ON mode.
●It is possible to switch to outside air mode
at any time by pressing the outside/recir-
culated air mode switch.
■Fogging up of the windows
●The windows will easily fog up when the
humidity in the vehicle is high. Pressing
“A/C” button or selecting “A/C” will
dehumidify the air from the outlets and
defog the windshield effectively.
●If you turn “A/C” off, the windows may
fog up more easily.
●The windows may fog up if the recircu-
lated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tun-
nels or in heavy traffic, set the outside/
recirculated air mode switch to the recir-
culated air mode. This is effective in pre-
venting outside air from entering the
vehicle interior. During cooling opera-
tion, setting the recirculated air mode will
also cool the vehicle interior effectively.
●Outside/recirculated air mode may auto-
matically switch de pending on the tem-
perature setting or the inside
temperature.
■Registering air condit ioning settings to
electronic keys (vehicles with driving
position memory)
●Unlocking the vehicle using an electronic
key and turning the power switch to ON
mode will recall that key’s registered air conditioning settings.
●When the power 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, con-
tact your Lexus dealer.
*: The doors that can recall the driving posi-
tion memory are changed at the same
time.
■Operation of the air conditioning sys-
tem in Eco mode
●In the Eco mode, the air conditioning sys-
tem is controlled as follows to prioritize
fuel efficiency
• Engine speed and compressor operation
controlled to restrict heating/cooling
capacity
• Fan speed restricted when automatic mode is selected
●To improve air conditioning performance,
perform the following operations
• Adjust the fan speed
• Adjust the temperature setting
• Turn off Eco mode
●Even when the driving mode is set to Eco
mode, the air conditioning eco mode can
be turned off by selecting the
■When the outside temperature is low
The dehumidification function may not
operate even when “A/C” is pressed or “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

●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 period of time imme-
diately after the air conditioning system is
started in automatic mode.

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.

faces when the outside rear view mir-
ror defoggers are on.

severe rear-end collision, the system is
designed to automatically call the
response center. The responding agent
receives the vehicle’s location and
attempts to speak with the vehicle
occupants to assess the level of emer-
gency. If the occupants are unable to
communicate, the ag ent automatically
treats the call as an emergency, con-
tacts the nearest emergency services
provider to describe the situation, and
requests that assistance be sent to the
location.

6-1.Maintenance and care
Working from top to bottom, liber-
ally apply water to the vehicle body,
wheel wells and underside of the
vehicle to remove any dirt and dust.
 Wash the vehicle body using a
sponge or soft cloth, such as a
chamois.
 For hard-to-remove marks, use car
wash soap and rinse thoroughly with
water.
 Wipe away any water.
 Wax the vehicle when the water-
proof coating deteriorates.
If water does not bead on a clean surface,
apply wax when the vehicle body is cool.
■Self-restoring coat
The vehicle body has a self-restoring coat-
ing that is resistant to small surface
scratches caused in a car wash etc.
●The coating lasts for 5 to 8 years from
when the vehicle is delivered from the
plant.
●The restoration time differs depending on
the depth of the scratch and outside tem-
perature. The restoration time may
become shorter when the coating is
warmed by applying warm water.
●Deep scratches caused by keys, coins,
etc. cannot be restored.
●Do not use wax that contain abrasives.
■Automatic car washes
●Before washing the vehicle:
• Fold the mirrors
• Turn off the power back door (if equipped)
Start washing from the front of the vehicle.
Extend the mirrors before driving.
●Brushes used in automatic car washes
may scratch the vehicl e surface and harm
your vehicle’s paint.
●Rear spoiler may not be washable in
some automatic car washes. There may
also be an increased risk of damage to
vehicle.
■High pressure car washes
●Do not allow the nozzles of the car wash
to come within close proximity of the win-
dows.
●Before using the car wash, check that the
fuel filler door on your vehicle is closed
properly.
■Note for a smart access system with
push-button start
●If the door handle becomes wet while the
electronic key is within the effective
range, the door may lock and unlock
repeatedly. In that case, follow the follow-
ing correction procedures to wash the
vehicle:
• Place the electronic key in a location 6 ft.
(2 m) or more away from the vehicle.
(Take care to ensure that the key is not
stolen.)
• Set the electronic key to battery-saving mode to disable the smart access system
with push-button start. ( P.121)
■Aluminum wheels
●Remove any dirt immediately by using a
neutral detergent.
●Wash detergent off with water immedi-
ately after use.
●To protect the paint from damage, make
sure to observe the following precau-
tions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when
