sensitivity can be adjusted by turning
the switch ring.
6 Increases the sensitivity
7 Decreases the sensitivity
8 Washer/wiper dual operation
The wipers will automatically operate a
couple of times after the washer squirts.
(After operating several times, the wipers
operate once more time after a short delay
to prevent dripping. However, the dripping
prevention does not operate while the
vehicle is moving.)
When the engine switch <power switch> is
in IGNITION ON mode <ON mode> and
the headlights are on, if the lever is pulled,
the headlight cleaners will operate once.
After this, the headlight cleaners will oper-
ate every 5th time the lever is pulled.
■The windshield wiper and washer can be
operated when
The engine switch <p ower switch> is in
IGNITION ON mode <ON mode>.
■Raindrop sensor
●The raindrop sensor judges the amount
of raindrops. An optical sensor is adopted. It may not operate properly when sunlight from the
rising or setting of the sun intermittently strikes the windshield, or if bugs etc. are present on the windshield.
●If the wiper is turned to AUTO position while the engine switch <power switch> is
in IGNITION ON mode <ON mode>, the wipers will operate once to show that AUTO mode is activated.
●If the temperature of the raindrop sensor is 85°C (185°F) or higher, or -30°C (-
22°F) or lower, automatic operation may not occur. In this case, operate the wipers in any mode other than AUTO.
■If no windshield washer fluid sprays

4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the accelera-
tor pedal depression amount can be
generated more smoothly than it is in
normal conditions. In addition, the
operation of the air conditioning sys-
tem (heating/cooling) will be mini-
mized, improving the fuel economy.
( P.242)
The Eco-friendly driving is possible by
keeping the indicate of Hybrid System
Indicator within Eco area. ( P.86)
Shift the shift position to D when
stopped at a traffic light, or driving in
heavy traffic etc. Shift the shift position
to P when parking. When using the N
position, there is no positive effect on
fuel consumption. In the N position, the
gasoline engine operates but electric-
ity cannot be generated. Also, when
using the air conditioning system, etc.,
the hybrid battery (traction battery)
power is consumed.
 Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration consumes
hybrid battery (traction battery)
power, resulting in poor fuel con-
sumption. Battery power can be
restored by driving with the acceler-
ator pedal slightly released.
Make sure to operate the brakes gently
and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.
Repeated acceleration and decelera-
tion, 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.
When driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly while
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.

Maintenance and care
Vehicles with front and rear tires of
the same size
Vehicles with front and rear tires of
differing sizes
To equalize tire wear and help extend tire
life, Lexus recommends that tire rotation is
carried out approximately every 10000
km (6000 miles).
Do not fail to initialize the tire pressure
warning system after tire rotation.
■When rotating the tires
Make sure that the engine switch <power switch> is off. If the tires are rotated while
the engine switch <power switch> is in IGNITION ON mode <ON mode>, the tire position information will not be updated.
If this accidentally occurs, either turn the engine switch <power switch> to off and then to IGNITION ON mode <ON mode>,
or initialize the tire pr essure warning system after checking that the tire pressure is prop-erly adjusted.
When run-flat tires are installed, the
vehicle can be driven for a maximum of
160 km (100 miles) at a speed below
80 km/h (50 mph) after any tire goes
flat. (However, the vehicle speed may
not increase to near 80 km/h [50
mph] depending on weather or driving
conditions.)
A run-flat tire has a mark on
the side wall.
Make sure to replace the flat tire before the
vehicle has been driven for near 160 km
(100 miles). Also, do not use a repaired
tire.
■Run-flat tires
●The run-flat tires are for only this vehicle. Do not use the tires on other vehicles.
●Do not mix run-flat tires and normal tires.
●If non-genuine Lexus wheels are used, it
may be impossible to sufficiently demon- strate the performanc e of run-flat tires.
Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.
 If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. ( P.374)
 The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information

7-2. Steps to take in an emergency
When trouble arises
■High coolant temperature warning light (warning buzzer)*
*: This light illuminates on the multi-information display.
■Front passenger detection sensor, seat belt reminder and warning buzzer
●If luggage is placed on a front passenger seat, the front passenger detection sensor may cause the warning light to flash and the warning buzzer to sound even if a passenger is not
sitting in the seat.
●If a cushion is placed on the seat, the sensor may not detect a passenger, and the warning
light may not operate properly.
■If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp w ill come on if the fuel tank becomes completely empty. If
the fuel tank is empty, refuel the vehicle immediately. The malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer as soon as possible.
■Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage temporarily drops, the electric power steering system warning lig ht may come on and the warning buzzer may sound.
■Tire pressure warning light
When a malfunction occurs in the tire pressure warning system, the tire pressure warning light blinks to warn the driver. However, if the warning light blinks for 1 minute, and then
remains illuminated, maki ng it difficult to determine whether the warning light is blinking, turn the engine switch <power switch> fr om off to IGNITION ON mode <ON mode> and check if the warning light blinks.
■When the tire pressure warning light comes on
Carry out the following procedure after the tire temperature has lowered sufficiently.
●Check the tire inflation pressure and adjust to the appropriate level.
●If the warning light does not go out even after several minutes, check that the tire inflation
pressure is at the specified level and carry out initialization. ( P.335)
The warning light may come on again if the above operations are conducted without first
allowing the tire temperature to lower sufficiently.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on du e to natural causes such as natural air leaks
and tire inflation pressure changes caused by temperature. In this case, adjusting the tire inflation pressure will turn off the warning light (after a few minutes).

7-2. Steps to take in an emergency
■Conditions that the tire pressure warning system may not function properly
 P.330
■If the tire pressure warning light frequently comes on after blinking for 1 minute
If the tire pressure warning lig ht frequently comes on after blinking for 1 minute when the engine switch <power switch> is turned to IGNITION ON mode <ON mode>, have it
checked by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location or audio sound.
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized Lexus retailer
or Lexus authorized repairer, or any reliabl e repairer. The vehicle will become extremely unstable during braking, and the ABS system may fail, which could cause an accident resulting in death or serious injury.
■When the electric power steering system warning light comes on
When the light comes on yellow, the assist to the power steering is restricted. When the
light comes on red, the assist to the power st eering is lost and handling operations of the steering wheel become extremely heavy. When steering wheel operations are heavier than usual, grip the steering wheel firmly and operate it using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a loss of vehi-
cle control and result in death or serious injury.
●Decelerate to the lowest appropriate speed as soon as possible. Do not drive over 80 km/h (50 mph).
●Check and adjust the tire inflation pressure immediately.
●If the tire pressure warning light comes on ev en after tire inflation pressure adjustment, it is probable that you have a flat tire. Have the flat tire replaced by nearest authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
