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).

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.

By keeping the indicator needle within

Eco area, more Eco-friendly driving can

be achieved.

●

Charge area indicates regeneration

*

sta-

charge the hybrid battery (traction bat-

tery).

*

: When used in this manual, “regeneration”

refers to the conversion of energy cre-

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.
