2-1. Driving procedures
CAUTION
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
■When the vehicle is stopped
●Do not race the hybrid system. 
If the vehicle is in any gear other than “P” or “N” the vehicle may accelerate sud-
denly and unexpectedly, and may cause an accident.
●Do not leave the vehicle with the hybrid system on for a long time. 
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do no t enter the vehicle interior.
●Always keep a foot on the brake pedal while the hybrid system is operating to
prevent an accident caused by the vehicle moving.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle when it is in the sun. 
Failure to do so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic
material of eye glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of
the vehicle, and may also cause a short circuit in the vehicle's electrical com-
ponents.
●Always apply the parking brake, shift the sh ift lever to “P”, stop the hybrid system
and lock the vehicle.
Do not leave the vehicle unattended while the hybrid system is operating.
●Do not touch the exhaust pipe while the hybrid system is operating or immedi-
ately after turning the hybrid system off. 
Doing so may cause burns.
●Do not leave the hybrid system operating in an area with snow build up, or where
snow is expected to fall. 
Exhaust gases may enter the vehicle and cause gas poisoning.

2-3. Operating the lights and windshield wipers
2
When driving
AFS (Adaptive Front lighting System)
AFS improves visibility at intersectio ns and on curves by automatically
adjusting the level of the headlights according to vehicle speed and the
degree of the tire angle that are controlled by steering input.
Operates at speeds of 6 mph (10 km/h) or higher.
■ Deactivating AFS
Press the switch to turn it OFF.
The indicator turns on when
the AFS is deactivated.
■Daytime running light system
To make your vehicle more visible to other drivers, the headlights turn on automati -
cally (at a reduced intensity) whenever the hy
brid system is started and the parking
brake is released. Daytime running lights are not designed for use at night.
■Headlight control sensor
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield. 
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

122
2-3. Operating the lights and windshield wipers
■Automatic light off system
The headlights and tail lights turn off 30 seconds after a door is opened or closed if
the power switch has been switched to “ACC” or turned “OFF” while the headlights
are turned on. (The lights turn off immediately if the button on the key is pressed
after all doors are locked.)
To turn the lights on again, switch to “IG-ON” mode, or turn the light switch “OFF”
once and then back to the or position.
■Automatic headlight leveling system
The level of the headlights is automatica lly adjusted according to the number of
passengers and the loading condition of the vehicle to ensure that the headlights do
not interfere with other road users.
■If the indicator flashes...
It may indicate a malfunction in the system. Contact your Lexus dealer.
■Customization
Settings (e.g. light sensor sensitivity) can be changed. ( P. 5 0 0 )
NOTICE
■To prevent 12 volt battery discharge
Do not leave the lights on longer than necessary when the hybrid system is off.

125
2-3. Operating the lights and windshield wipers
2
When driving
■Rain drop sensor
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
■In extremely hot or cold weather
The system will turn off if the windshield gets extremely hot (at more than 176 F
[80 C]) or cold (at less than 14 F [-10C]).
■Customization
Settings (e.g. drip prevention function) can be changed. ( P. 500)
CAUTION
■Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or the
windshield is subject to vibration in “AUT O” mode. Take care that your fingers or
anything else do not become caught in the windshield wipers.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled toward you
and held continually.
The sensor judges the amount of raindrops.

2-4. Using other driving systems
Driving assist systems
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Restrains the vehicle from slipping when driving on slick road surfaces or
in the event of sudden braking.
■BA (Brake Assist)
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding wh en swerving suddenly or turning on
slippery road surfaces.
■ TRAC (Traction Control)
Maintains drive power and prevents the rear wheels from spinning when
starting the vehicle or accelerating on slippery roads.
■Hill-start assist control
Helps prevent the vehicle from rolling backwards when starting on an
incline or slippery slope. It operat es for approximately 5 seconds at maxi -
mum.
■ VGRS (Variable Gear Ratio Steering)
Adjusts the wheel turning angle in accordance with the vehicle speed and
steering wheel movement.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.
■Active stabilizer suspension system
Turns at smaller angles to main tain the stable vehicle posture.

168
2-4. Using other driving systems
■The pre-collision system is operational when
●Seat belt (linked to the radar sensor)
• Vehicle speed is above 3 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or oncoming vehicle exceeds 18 mph (30 km/h).
• The front occupants are wearing a seat belt.
●Seat belts (linked to brake operation)
• Vehicle speed exceeds 9 mph (15 km/h).
• The system detects sudd en braking or skidding.
• The front occupants are wearing a seat belt.
●Brake Assist
• Vehicle speed is above 18 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or oncoming vehicle exceeds 18 mph (30 km/h).
• The brake pedal is depressed.
●AV S
• Vehicle speed is above 3 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or oncoming vehicle exceeds 18 mph (30 km/h).
■Conditions that may trigger the system even if there is no danger of collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface
●When passing an oncoming vehicle on a left-turn
●When your vehicle rapidly closes on the vehicle in front
When the system is activated in the situations described above there is also a possi-
bility that the seat belts will retract quickly and the brakes will be applied with a force
greater than normal. When the seat belt is locked in the retracted position, stop the
vehicle in a safe place, release the seat belt and refasten.
■When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. ( P. 432, 439)
