■If a warning light comes on, a warning message is displayed, or the 12-volt battery is
disconnected
The hybrid system may not start. In that case, try to start the system again. If the
“READY” indicator does not come on, contact your Lexus dealer.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel
the vehicle with at least enough gasoline to make the low fuel level warning light
(  P. 496) go off. If there is only a small amount of fuel, the hybrid system may not be
able to start. (The minimum amount of fuel to add to make the low fuel level warning
light go out is about 3.4 gal. [13 L, 2.8 Imp. gal.], when the vehicle is on a level sur-
face. This value may vary when the vehicle is on a slope.)
■Electromagnetic waves
●High voltage parts and cables on the hybr id vehicles incorporate electromagnetic
shielding, and therefore emit approximately the same amount of electromagnetic
waves as conventional gasoline powered vehicles or home electronic appliances.
●Your vehicle may cause sound interference in some third party-produced radio
parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of the
hybrid battery (traction battery) can change in accordance with driving style and
driving conditions.

When the power switch is turned to ON mode, the red indicator light
comes on for 2 seconds then turns off. Afterward, the green indicator light
comes on, indicating that the service is active.
The following indicator light patter ns indicate specific system usage con-
ditions:
●Green indicator light on = Active service
●Green indicator light flashing = Safety Connect call in process
●Red indicator light (except at vehicle start-up) = System malfunction
(contact your Lexus dealer)
●No indicator light (off) = Safety Connect service not active
■Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the
system is designed to automatically call the response center. The
responding agent receives the vehicl e’s location and attempts to speak
with the vehicle occupants to assess the level of emergency. If the occu-
pants are unable to communicate, th e agent automatically treats the
call as an emergency, contacts th e nearest emergency services pro-
vider to describe the situation, and re quests that assistance be sent to
the location.

■Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhanc ing additive called MMT (Methylcyclo-
pentadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasoli ne 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 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 us ing 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.
