WARNING

If a safety system warning light does

not come on

Should a safety system light such as the

ABS and SRS warning light not come on

when you start the EV system, this could

mean that these systems are not avail-

able to help protect you in an accident,

which could result in death or serious

injury. Have the vehicle inspected by any

authorized Lexus retailer or Lexus

authorized repairer, or any reliable

repairer immediately if this occurs.

Charge area

Shows regeneration

status.

Regenerated energy will be used to
charge the traction battery.

Eco area

Shows that the vehicle is being driven in an
Eco-friendly manner.
By keeping the bar display within Eco area,
more Eco-friendly driving can be
achieved.

Power area

Shows that an Eco-friendly driving range is
being exceeded (during full power driving
etc.)

: When used in this manual, regeneration

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

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 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

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 regenerative

braking power appearing on the display.

This lag could cause the driver to down-

shift again, causing rapid and excessive

regenerative braking and possibly an

accident resulting in death or injury.

Card key (if equipped)

The mechanical key that is stored inside

the card key should be used only if a

problem arises, such as when the card

key does not operate properly.

If the battery cover is not installed and the

battery falls out or if the battery was

removed because the key got wet, rein-

stall the battery with the positive terminal

facing the Lexus emblem.

The card key is not waterproof.

When riding in an aircraft

When bringing an electronic key onto an

aircraft, make sure you do not press any

buttons on the electronic key while inside

the aircraft cabin. If you are carrying an

electronic key in your bag, etc., ensure that

the buttons are not likely to be pressed

accidentally. Pressing a button may cause

the electronic key to emit radio waves that

could interfere with the operation of the air-

craft.

Electronic key battery depletion

The standard battery life is 1 to 2 years.

(The card key battery life is from one year

to one year and a half.)

If the battery becomes low, an alarm will

sound in the cabin when the EV system

stops.

To reduce key battery depletion when

the electronic key is to not be used for

long periods of time, set the electronic

key to the battery-saving mode.

(



P.197)

As the electronic key always receives

radio waves, the battery will become

depleted even if the electronic key is not

Failure to do so may cause parts of the

body to be caught, resulting in death or

serious injury.

Remove any heavy loads, such as

the back door in windy weather as it

may move abruptly in strong wind.

Vehicles without power back door:

The back door may suddenly shut if it is

not opened fully. It is more difficult to

open or close the back door on an

incline than on a level surface, so

beware of the back door unexpectedly

opening or closing by itself. Make sure

that the back door is fully open and

secure before using the luggage com-

partment.

Vehicles with power back door: The

back door may suddenly shut if it is not

opened fully, while on a steep incline.

(



P.192) to close the back door, and

do not hang on the back door damper

stay (vehicles without power back

door) or back door spindle (vehicles

caught or the back door damper stay

(vehicles without power back door) or

back door spindle (vehicles with

power back door) to break, causing an

accident.

If a bicycle carrier or similar heavy

object is attached to the back door, it

may suddenly shut again after being

opened, causing someone’s hands,

arms, head or neck to be caught and

injured. When installing an accessory

part to the back door, using a genuine

Lexus part is recommended.
