Fuel information

■

Use of ethanol blended gasoline in a gasoline engine

Lexus allows the use of ethanol blended gasoline where the ethanol content is up to 10%.

Make sure that the ethanol blended gasoline to be used has a Research Octane Number

that follows the above.

■

If your engine knocks

●

Consult any authorized Lexus retailer or Lexus authorized repairer, or any reliable

repairer.

●

You may occasionally notice light knocking for a short time while accelerating or driv-

ing uphill. This is normal and there is no need for concern.

When you find these types of fuel label at the gas station, use only the fuel with
one of the following labels.

 

EU area:
You  must  only  use  unleaded  gasoline  conforming  to  European  standard
EN228.
Select unleaded gasoline with a Research Octane Number of 95 or higher for
optimum engine performance.
Except EU area:
You must only use unleaded gasoline.
Select unleaded gasoline with a Research Octane Number of 95 or higher for

Vehicle customization

●

When the speed linked door locking function and the shift position linked door locking

function are both on, the door lock operates as follows.
• When shifting the shift position to any position other than P, all the doors will be

locked.

• If the vehicle is started with all the doors locked, the speed linked door locking func-

tion would not operate.

• If the vehicle is started with any door unlocked, the speed linked door locking func-

tion will operate.

●

When the smart entry & start system is off, smart door unlocking cannot be custom-

ized.

●

When the doors remain closed after unlocking the doors and the automatic door lock

function is activated, the signals will be generated in accordance with the Operation

signal (buzzer) and the Operation signal (emergency flashers) settings.

■

In the following situations, customize mode in which the settings can be changed

through the multi-information display will automatically be turned off.

●

A warning message appears after the customize mode screen is displayed.

●

The power switch is turned off.

●

The vehicle begins to move while the customize mode screen is displayed.

WARNING

■

Cautions during customization

As the hybrid system needs to be operating during customization, ensure that the vehi-

cle is parked in a place with adequate ventilation. In a closed area such as a garage,

exhaust gases including harmful carbon monoxide (CO) may collect and enter the

vehicle. This may lead to death or a serious health hazard.

NOTICE

■

During customization

To prevent 12-volt battery discharge, ensure that the hybrid system is operating while

customizing features.
