For safety and security

Air intake vents

Air discharge vents

When a certain level of impact is 
detected by the impact sensor, the 
emergency shut off system blocks the 
high voltage current and stops the fuel 
pump to minimize the risk of electrocu-
tion and fuel leakage. If the emergency 
shut off system activates, your vehicle 
will not restart. To restart the hybrid 
system, contact your Lexus dealer.

A message is automatically displayed 
when a malfunction occurs in the 
hybrid system or an improper opera-
tion is attempted.
If a warning message is shown on the 
multi-information display, read the 
message and follow the instructions.

NOTICE

■

Hybrid battery (traction battery) air 

intake and discharge vents

●

Do not place objects that will block the 

air intake vents. The hybrid battery 

(traction battery) may have a reduc-

tion in hybrid battery (traction battery) 

output as well as be damaged.

●

Clean the air intake and discharge 

vents regularly to prevent the hybrid 

battery (traction battery) from over-

heating.

●

Do not get water or foreign materials 

in either the air intake and discharge 

vents as this may cause a short circuit 

and damage the hybrid battery (trac-

tion battery).

●

If “Maintenance required for Traction 

battery cooling parts See owner’s 

manual” is shown on the multi-informa-

tion display, clean the air intake vents 

(



P.337). If the message is still dis-

played after cleaning the air intake 

vents, have the vehicle inspected by 

your Lexus dealer.

●

A filter is installed to the air intake vent. 

When the filter remains noticeably 

dirty even after cleaning the air intake 

vent, filter cleaning or replacement is 

recommended. For information 

regarding filter cleaning or replace-

ment, contact your Lexus dealer.

WARNING

■

If a safety system warning light does 

not come on

Should a safety system light such as the 

ABS and SRS airbag warning light not 

come on when you start the hybrid sys-

tem, this could mean that these systems 

are not available to help protect you in an 

accident, which could result in death or 

serious injury. Have the vehicle inspected 

by your Lexus dealer immediately if this 

occurs.

power driving etc.)

Eco area
Shows that the vehicle is being driven in 
an Eco-friendly manner.

Hybrid Eco area
Shows that gasoline engine power is not 
being used very often.
The gasoline engine will automatically 
stop and restart under various condi-
tions.

Charge area
Shows that energy is being recovered 
via the regenerative brake.

●

Hybrid System Indicator is displayed 

when the driving mode is in other than 

the Sport mode.

●

By keeping the indicator needle within 

Eco area, more Eco-friendly driving can 

be achieved.

●

Charge area indicates regeneration

*

 sta-

tus. Regenerated energy will be used to 

charge the hybrid battery (traction bat-

tery).

*

: When used in this manual, “regeneration” 

refers to the conversion of energy cre-
ated by the movement of the vehicle into 
electrical energy.

■

Tachometer

Hybrid System Indicator switches to the 

tachometer when driving mode is in Sport 

mode. The settings of the tachometer dis-

play can be changed on the multi-informa-

tion display.

■

Engine speed

On hybrid vehicles, engine speed is pre-

cisely controlled in order to help improve 

fuel efficiency and reduce exhaust emis-

sions, etc.

There are times when the engine speed that 

is displayed may differ even when vehicle 

operation and driving conditions are the 

same.

■

Outside temperature display

●

In the following situations, the correct 

outside temperature may not be dis-

played, or the display may take longer 

than normal to change.

• When stopped, or driving at low speeds 

(less than 12 mph [20 km/h])

• 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 your Lexus dealer.

■

Pop-up display

In some situations, a pop-up display will be 

temporarily displayed on the multi-informa-

Instrument panel brightness adjustment

The instrument panel brightness levels 

when the tail lights are on and off can be 

adjusted individually. However, when the 

surroundings are bright (daytime, etc.), 

turning on the tail lights will not change the 

instrument panel brightness. At this time, 

any adjustments made to the instrument 

panel brightness levels will be applied to 

both settings at once.

WARNING

■

The information display at low tem-

peratures

Allow the interior of the vehicle to warm 

up before using the liquid crystal infor-

mation display. At extremely low tem-

peratures, the information display 

monitor may respond slowly, and display 

changes may be delayed.

For example, there is a lag between the 

driver’s shifting and the new gear number 

appearing on the display. This lag could 

cause the driver to downshift again, 

causing rapid and excessive engine brak-

ing and possibly an accident resulting in 

personal death or injury.

NOTICE

■

To prevent damage to the engine and 

its components

●

When the tachometer is displayed, 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 

engine coolant temperature gauge is 

in the red zone (H); or “Engine Cool-

ant Temp High” or “Hybrid System 

Overheated” is shown on the multi-

information display. In this case, imme-

diately stop the vehicle in a safe place, 

and check the engine or hybrid system 

after it has cooled completely.
