Sport mode
• SPORT S mode
Assists acceleration response by controlling the transmission and
the engine. Suitable for when powerful acceleration is desirable.
When not in SPORT S mode and the driv ing mode select switch is turned to
the right, the “SPORT S” indicator comes on in the multi-information display.
• SPORT S+ mode
Helps to ensure steering performance and driving stability by simul-
taneously controlling the steering and suspension in addition to the
transmission. Suitable for sporty driving.
When in SPORT S mode and the driving mo de select switch is turned to the
right, the “SPORT S+” indicator comes on in the multi-information display.
■Operation of the air conditioni ng system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the air
conditioning system to enhance fuel efficiency ( P. 418). To improve air condition-
ing performance, adjust the fan speed or turn off Eco drive mode.
■Sport mode automatic deactivation
Sport mode is automatically deactivated if the engine switch is turned off after driv-
ing in sport mode.
■Driving mode pop-up display
When the driving mode is changed, the selected driving mode will be temporarily
displayed on the side display. ( P. 415)

Driving
LS460/LS460L_GE (OM50G06E)
◆Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accelerator
pedal depression amount can be generate d more smoothly than it is in normal
conditions. In addition, the operation of the air conditioning system (heating/
cooling) will be minimized, improving the fuel economy. ( P. 354)
◆Use of Eco Driving Indicator
The Eco-friendly driving is possible by keeping the bar display of the Eco Driv-
ing Indicator shown in the multi-information display within the Zone of Eco
driving. (  P. 132)
◆Accelerator pedal/brake pedal operation
Drive your vehicle smoothly. Avoid abrupt acceleration and deceleration.
Gradual acceleration and deceleration will help reduce excessive fuel con-
sumption.
◆When braking
Observe conditions in front of and ar ound the vehicle, and estimate your
stopping position. Release the accelerator pedal early and continue coasting.
Use the brake pedal to adjust your stopping position. Make sure to operate
the brake pedal gently.
◆Delays
Repeated acceleration and deceleration, as well as long waits at traffic lights,
will lead to bad fuel economy. Check traffic reports before leaving and avoid
delays as much as possible.
◆Highway 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 pedal and gen-
tly apply the brakes.
Eco-friendly driving tips
For improved fuel economy and reduced CO2 emissions, pay attention to the

4345-3. Using the air conditioning system and defogger
LS460/LS460L_GE (OM50G06E)
■Operation of the air conditioning system in Eco drive mode
●In the Eco drive mode, the air conditioning system is controlled as follows to priori-
tize 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
• Turn off Eco drive mode
■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature setting and
ambient conditions. As a result, the following may occur:
●Immediately after the “AUTO” switch is pressed, the fan may stop for a while until
warm or cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Selecting
“A/C” on will dehumidify the air from the outlets and defog the windshield effec-
tively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/
recirculated air mode button to the recirculated air mode. This is effective in pre-
venting outside air from entering the vehicle interior. During cooling operation, set-
ting the recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.

CAUTION
■Burns/excessive cooling
●Use caution when seating the following persons in a seat to avoid the possibility of
burns or excessive cooling:
• Babies, small children, elderly persons, sick persons and persons with a physi-
cal disability
• Persons who have sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs which induce sleep, such as sleeping
drugs and cold remedies
●Do not cover the seat with anything when using the climate control seat or seat
heater. Using the climate control seat or seat heater with a blanket or cushion
may increase or decrease the temperature of the seat, resulting in overheating or
overcooling.
●Do not use the climate control seat or seat heater more than necessary. Doing so
may cool the occupants excessively or may cause minor burns or overheating.
NOTICE
■To prevent damage to the climate control seat and seat heater
Do not put heavy objects that have an uneven surface on the seat and do not stick
sharp objects, such as needles and nails, into the seat.
■To prevent the battery from being discharged
Do not leave the system on longer th an necessary when the engine is off.

Maintenance and care
LS460/LS460L_GE (OM50G06E)
6-2. Maintenance
●Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.
The interval for scheduled maintenance is determined by the odometer reading
or the time interval, whichever comes first, shown in the schedule.
Maintenance beyond the last period should be performed at the same intervals.
●Where to go for maintenance service?
It makes good sense to take your vehicle to your local Lexus dealer for mainte-
nance service as well as other inspections and repairs.
Lexus technicians are well-trained specialists receiving the latest service informa-
tion through technical bulletins, service tips and in-dealership training programs.
They learn to work on Lexus before they work on your vehicle, rather than while
they are working on it. Doesn’t that seem like the best way?
Your Lexus dealer has invested a lot of money in special Lexus tools and service
equipment. It helps them to do the job better and at less cost.
Your Lexus dealer’s service department will perform all of the scheduled mainte-
nance on your vehicle reliably and economically.
Rubber hoses (for cooling and heater system, brake system and fuel system)
should be inspected by a qualified technician according to the Lexus mainte-
nance schedule.
Rubber hoses are particularly important maintenance items. Have any deterio-
rated or damaged hoses replaced immediately. Note that rubber hoses will dete-
riorate with age, resulting in swelling, chafing or cracking.
Maintenance requirements
To ensure safe and economical driving, day-to-day care and regular
maintenance are essential. Lexus recommends the following mainte-
nance:

Tire inflation pressure (P. 568)• Tire pressure gauge
• Compressed air source
Washer fluid ( P. 553)
• Water or washer fluid containing anti-
freeze (for winter use)
• Funnel (used only for adding water or
washer fluid)
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious
injury, observe the following precautions.
■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage painted
surfaces. If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience disc omfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fans may
automatically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( P. 549)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from get-
ting in your eyes.
