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.
When refueling, the fuel filler door may take a few moments to open
■
As part of emission system operation, it may 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. 110)
Electromagnetic waves
■
High voltage parts and cables on the hybrid vehicles incorporate electromag-
●
netic shielding, and therefore 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.
Consult your Lexus dealer before installing or removing third party-produced
●
radio parts.
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. 566) 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)
■
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.
