●Hybrid System Indicator is displayed when the driving mode is in other than the sport
mode.
●By keeping the indicator needle within Ec o area, more Eco-friendly driving can be
achieved.
●Charge area indicates regeneration* status. Regenerated energy will be used to
charge the hybrid battery (traction battery).
*: When used in this manual, “regeneration” refers to the conversion of energy created
by the movement of the vehicle into electrical energy.
■Tachometer (if equipped)
The tachometer is displayed when the driving mode is in the sport mode.
■ECO lamp and SPORT lamp (if equipped)
●When sport mode is selected, the SPORT lamp (red) will illuminate.
●When all of the following conditions are satisfied and the Eco-friendly driving, the ECO
lamp (blue) will illuminate:
• Driving with the shift position in D
• Either normal mode or Eco drive mode is selected, and EV drive mode is not in use
( → P. 1 8 1 , 2 3 7 )
• The vehicle speed is approximately 130 km/h (80 mph) or below.
■Engine speed
On hybrid vehicles, engine speed is precis ely controlled in order to help improve fuel
efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may differ even when vehicle
operation and driving co nditions are the same.
■Outside temperature display
●In the following situations, the correct outside temperature may not be displayed, or the
display may take longer than normal to change.
• When stopped, or driving at low speeds (less than 20 km/h [12 mph])
• When the outside temperature has changed suddenly (at the entrance/exit of a
garage, tunnel, etc.)
●When “--” or “E” is displayed, the system may be malfunctioning.
Take your vehicle to any authorized Lexus de aler or repairer, or another duly qualified
and equipped professional.
■Customization
Settings (e.g. on/off operation of the ECO lamp) can be changed.
(Customizable features: →P. 5 8 9 )
NOTICE
■To prevent damage to the engine and its components
●Vehicles with tachometer: Do not let the indicator needle of the tachometer enter the
red zone, which indicates the maximum engine speed.
●The engine may be overheating if the high coolant temperature warning light comes
on or flashes. In this case, immediately stop the vehicle in a safe place, and check the
engine after it has cooled completely. ( →P. 5 7 1 )

Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY” indicator is
illuminated. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty in oper-
ating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly. This allows you to depress the brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using
your left foot may delay response in an emergency, resulting in an accident.
●The driver should pay extra attention to pedestrians when the vehicle is powered only
by the electric motor (traction motor). As there is no engine noise, the pedestrians
may misjudge the vehicle’s movement.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.
●During normal driving, do not turn off the hybrid system. Turning the hybrid system off
while driving will not cause loss of steering or braking control, however, power assist
to the steering will be lost. This will make it more difficult to steer smoothly, so you
should pull over and stop the vehicle as soon as it is safe to do so. In the event of an
emergency, such as if it becomes impossib le to stop the vehicle in the normal way:
→ P. 5 0 9
●Use engine braking (shift position B instea d of shift position D) to maintain a safe
speed when driving down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effective-
ness. ( →P. 1 8 4 )
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside rear
view mirrors while driving.
Doing so may result in a loss of vehicle control.
●Always check that all passengers’ arms, heads or other parts of their body are not
outside the vehicle.

Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is stopped
●Do not depress the accelerator pedal unnecessarily.
If the shift position is any position other than P or N, the vehicle may accelerate sud-
denly and unexpectedly, causing an accident.
●In order to prevent accidents due to the vehicle rolling away, always keep depressing
the brake pedal while stopped with the “R EADY” indicator is illuminated, and apply
the parking brake as necessary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the exhaust
system to overheat, which could result in a fire if combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spra y cans, or soft drink cans in the vehicle
when it is in the sun.
Doing 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 mate-
rial of 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 components.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place such as
the glove box or on the floor, it may be lit accidentally when luggage is loaded or the
seat is adjusted, causing a fire.
●Do not attach adhesive discs to the windshield or windows. Do not place containers
such as air fresheners on the instrument panel or dashboard. Adhesive discs or con-
tainers may act as lenses, causing a fire in the vehicle.
●Do not leave a door or window open if the curved glass is coated with a metallized
film such as a silver-colored one. Reflected sunlight may cause the glass to act as a
lens, causing a fire.
●Always apply the parking brake, shift the shift position to P, stop the hybrid system and
lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illuminated.
●Do not touch the exhaust pipe while the “READY” indicator is illuminated or immedi-
ately after turning the hybrid system off.
Doing so may cause burns.

■When the “TRC OFF” indicator comes on even if the TRC OFF switch has not been
pressed
TRC cannot be operated. Contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
■Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
●A sound may be heard from the engine compartment when the hybrid system is
started, just after the vehicle begins to move, if the brake pedal is depressed forcefully
or repeatedly, or 1-2 minutes after the hybrid system is stopped. This sound does not
indicate that a malfunction has occurred in any of these systems.
●Any of the following conditions may occu r when the above systems are operating.
None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slig htly after the ABS is activated.
• The brake pedal may move down s lightly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be heard.
This does not indicate a malfunction.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The steering
wheel may feel heavy as a result. Should this occur, refrain from excessive steering input
or stop the vehicle and turn the hybrid system off. The EPS system should return to nor-
mal within 10 minutes.
■Automatic reactivation of TRC system
After turning the TRC system off, the system will be automatically re-enabled in the fol-
lowing situations:
●When the power switch is turned off
●The TRC will turn on when vehicle speed increases
■Operating conditions of emergency brake signal
When the following three conditions are me t, the emergency brake signal will operate:
●The emergency flashers are off.
●Actual vehicle speed is over 55 km/h (35 mph).
●The brake pedal is depressed in a manner that cause the system to judge from the vehi-
cle deceleration that this is a sudden braking operation.
■Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the following situations:
●The emergency flashers are turned on.
●The brake pedal is released.
●The system judges from the vehicle deceleration that is not a sudden braking operation.
