If a warning light comes on or a warning message is displayed, or the 12-volt bat-
tery is disconnected
The hybrid system may not start. In that ca se, try to start the system again. If the
“READY” indicator does not come on, contact your Lexus dealer.■
When refueling, the fuel filler door may take a few moments to open
As part of emission system operation, it ma y take up to 10 seconds for the fuel filler
door to automatically release after the opener switch is pressed. Before refueling is
possible, a message will be shown on the multi-information display. (  P. 119, 755)■
Electromagnetic waves ●
High voltage parts and cables on the hybrid vehicles incorporate electromag-
netic shielding, and theref ore emit approximately the same amount of electro-
magnetic waves as conventional gasoline powered vehicles or home electronic
appliances.●
Your vehicle may cause sound interference in some third party-produced radio
parts.■
Running out of fuel
When the vehicle has run out of fuel and th e hybrid system cannot be started, refuel
the vehicle with at least enough gasoline to make the low fuel level warning light
(  P. 733) 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 2.7 gal. [10.1 L, 2.2 Imp. gal.] when the vehicle is on a
level surface. This value may vary when the vehicle is on a slope.)■
Hybrid battery (traction battery)

Before driving Hybrid vehicle driving tips For economical and ecological driving, pay attention to the following
points:
■ Use of Hybrid System Indicator More Eco-friendly driving is possib le by keeping the indicate of Hybrid
System Indicator within Eco area.
■ When braking the vehicle Make sure to operate the brakes ge ntly and in good time. A greater
amount of electrical energy can be retained when slowing down.
■ Delays Repeated acceleration and deceleration, as well as long waits at traffic
lights, will lead to bad fu el consumption. Check traffic reports before leav-
ing and avoid delays as much as possible. When encountering a delay,
gently release the brake pedal to allow the vehicle to move forward slightly
while avoiding overuse of the accelerato r pedal. Doing so can help control
excessive gasoline consumption.
■ Highway driving Control your speed and keep at a constant speed. Also, before stopping at
a toll booth or similar, allow plenty of time to release the accelerator and
gently apply the brakes. A greater amount of electrical energy can be
retained when slowing down.
■ Air conditioning Use the air conditioning only when necessary. Doing so can help control
excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode. Doing so
will help to reduce the burden on the air conditioning and reduce fuel con-
sumption as well.
In winter: Because the gasoline engine will not automatically cut out until
the gasoline engine and the interior of the vehicle are warm, it will con-
sume fuel. Also, fuel consumption can be improved by avoiding overuse of
the heater.
