8-1. Specifications
■If your engine knocks
●Consult your Lexus dealer.
●You may occasionally notice light knocking for a short time while accelerating or
driving uphill. This is normal and there is no need for concern.
NOTICE
■Notice on fuel quality
●Do not use improper fuels. If improper fuels are used, the engine will be dam-
aged.
●Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic convert-
ers causing the emission control system to malfunction.
●Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performance problems.
●Using unleaded gasoline with an octane number or rating lower than the level
previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■Fuel-related poor driveability
If poor driveability is encountered after using a different type of fuel (poor hot start-
ing, vaporization, engine knocking, etc.), discontinue the use of that type of fuel.
■When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle’s paint.
