8-1. Specifications
Non-recommendation of the use of gas-
■
oline containing MMT
Some gasoline contains an octane enhanc-
ing additive called MMT (Methylcyclopen-
tadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gas-
oline that contains MMT. If fuel containing
MMT is used, your emission control system
may be adversely affected.
The malfunction indicator lamp on the
instrument cluster may come on. If this hap-
pens, contact your Lexus dealer for service.
If your engine knocks
■
Consult your Lexus dealer.
●
●
You may occasionally notice light knock-
ing 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 con-
verters 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 prob-
lems.
Using unleaded gasoline with an
●
octane number or rating lower than
the level previously stated may cause
persistent heavy knocking.
At worst, this may lead to engine dam-
age and will void the vehicle warranty.
Fuel-related poor driveability
■
If poor driveability (poor hot starting,
vaporization, engine knocking, etc.) is
encountered after using a different type
of fuel, discontinue the use of that type of
fuel.
