●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 )

WA R N I N G
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the shift lever or
depress the accelerator pedal, this could cause an accident or fire due to hybrid system
overheating. Additionally, if the vehicle is parked in a poorly ventilated area, exhaust
gases may collect and enter the vehicle, leading to death or a serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side of
the vehicle to brake differently than the other side. Also, the parking brake may not
securely hold the vehicle.
●If the electronically controlled assist function does not operate, do not follow other
vehicles closely and avoid downhill or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be depressed more
firmly than usual. Also, th e braking distance will increase. Have your brakes fixed
immediately.
●The brake system consists of 2 or more individual hydraulic systems; if one of the sys-
tems fails, the other(s) will still operate. In this case, the brake pedal should be
depressed more firmly than usual and the braking distance will increase. Have your
brakes fixed immediately.
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving, as
this may restrain driving torque.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at the
same time to hold the vehicle on a hill.
■When parking the vehicle
Always shift the shift position to P. Failure to do so may cause the vehicle to move or the
vehicle may accelerate suddenly if the accelerator pedal is accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in ei ther direction and hold it there for an
extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damaging
the wheels, underside of the vehicle, etc.

■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.

Turns the heated steering wheel on/off
The indicator light comes on when the
heated steering wheel is operating.
●The heated steering wheel can be used when the power switch is in ON mode.
●The heated steering wheel will automatically turn off after about 30 minutes.
∗: If equipped
Heated steering wheel and seat heaters heat the side grips of the steering

• Babies, small children, the elderly, the sick and the physically challenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping drugs, cold
remedies, etc.)

• Do not cover the seat with a blanket or cushion when using the seat heater.
• Do not use seat heater more than necessary.
NOTICE
●Do not put heavy objects that have an uneven surface on the seat and do not stick
sharp objects (needles, na ils, etc.) into the seat.
●To prevent 12-volt battery discharge, do not use the functions when the hybrid system
is off.

Indicates that the EV drive mode is not available*The reason the EV drive mode is not available (the
vehicle is idling, battery charge is low, speed is higher
than the EV drive mode operating speed range, accel-
erator pedal is depressed too much) may be dis-
played.
A buzzer also sounds.
→ Use the EV drive mode when it becomes available.
