761-2. Hybrid system
ES350 300h_OM_OM33A01U_(U)
■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. 754) 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 3.0 gal. [11.3 L, 2.5 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.

■The meters and display illuminate when
The “START STOP ENGINE” <“POWER”> switch is in IGNITION ON
mode.
■Instrument panel brightness adjustment
The instrument panel brightness levels wh en the tail lights are on and off can be
adjusted individually. However, when the surroundings are bright (daytime, etc.),
turning on the tail lights will not change th e instrument panel brightness. At this time,
any adjustments made to the instrument panel brightness levels will be applied to
both settings at once.
■Limitation of brightness adjustment
The brightness of the instrument panel ligh ts is automatically adjusted based on the
light sensor detecting how bright the surroundings are. However, if the instrument
panel brightness has been manually set to ei ther the brightest or darkest setting, the
automatic adjustment will not be performed.

■Hybrid System Indicator (hybrid vehicles)
●Hybrid System Indicator is displayed when the driving mode is other than the sport
mode.
●By keeping the indicator needle within Ec o area, more Eco-friendly driving can be
achieved.
●Charge area indicates regeneration* status. Regenerated energy will be used to
charge the battery.
*: When used in this manual, “regeneration” refers to the conversion of energy cre-
ated by the movement of the vehicle into electrical energy. Po w e r a r e a
Shows that an Eco-friendly driving range is
being exceeded (during full power driving
etc.)
Eco area
Shows that the vehicle is being driven in an
Eco-friendly manner.
Hybrid Eco area
Shows that gasoline engine power is not
being used very often.
The gasoline engine will automatically stop
and restart under various conditions.
Charge area
Shows regenerative charging.

■ECO lamp and SPORT lamp
●When sport mode is selected, SPORT lamp (red) will illuminate.
●When all of the following conditions are satisfied and Eco-friendly driving, ECO
lamp (blue) will illuminate. (ECO lamp will become brighter the more Eco-friendly
driving you perform. Also, while the vehicle is stopped or the acceleration exceeds
Zone of Eco driving, ECO lamp turns off. (P. 105) However, when Eco drive
mode is selected, while the vehicle is stopped or the acceleration exceeds Zone of
Eco driving, ECO lamp does not turn off.):
• Driving with the shift lever in D
• Either normal mode or Eco drive mode is selected.
• The vehicle speed is approximately 80 mph (130 km/h) or below.
■Tachometer (hybrid vehicles)
Hybrid System Indicator automatically sw itches to the tachometer when driving
mode is in sport mode.
■Engine speed (hybrid vehicles)

NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indi-
cates the maximum engine speed.
●The engine may be overheating if the engine coolant temperature gauge is in the
red zone (H). In this case, immediately stop the vehicle in a safe place, and check
the engine after it has cooled completely. ( P. 8 1 3 , 8 1 6 )
