For safety and security
*: When the hybrid battery (traction bat-tery) requires charging or the engine is 
warming up, etc., the gasoline engine will 
not automatically stop.
■During normal driving
The gasoline engine is predominantly 
used. The electric motor (traction 
motor) charges the hybrid battery 
(traction battery) as necessary.
■When accelerating sharply
When the accelerator pedal is 
depressed heavily, the power of the 
hybrid battery (traction battery) is 
added to that of the gasoline engine via 
the electric motor (traction motor).
■When braking (regenerative brak-
ing)
The wheels operate the electric motor 
(traction motor) as a power generator, 
and the hybrid battery (traction bat-
tery) is charged.
■Regenerative braking
In the following situations, kinetic energy is 
converted to electric energy and decelera-
tion force can be obta ined in conjunction 
with the recharging of the hybrid battery 
(traction battery).
●The accelerator pedal is released while 
driving with the shift position in D or M.
●The brake pedal is depressed while driv-
ing with the shift position in D or M.
■EV indicator
The EV indicator comes on when the vehi-
cle is driven using only the electric motor 
(traction motor) or th e gasoline engine is 
stopped.
■Conditions in which the gasoline engine 
may not stop
The gasoline engine starts and stops auto-
matically. However, it may not stop auto-
matically in the following conditions
*:
●During gasoline engine warm-up
●During hybrid battery (traction battery) 
charging
●When the temperature of the hybrid bat-
tery (traction battery) is high or low
●When the heater is switched on
●When the shift position is in M*: Depending on the circumstances, the  gasoline engine may also not stop auto-
matically in other situations.
■Charging the hybrid battery (traction 
battery)
As the gasoline engine charges the hybrid 
battery (traction battery), the battery does 
not need to be charged from an outside 
source. However, if the  vehicle is left parked 
for a long time the hybrid battery (traction 
battery) will slowly discharge. For this rea-
son, be sure to drive the vehicle at least 
once every few months for at least 30 min-
utes or 10 miles (16 km ). If the hybrid bat-
tery (traction battery) becomes fully 
discharged and you are unable to start the 
hybrid system, contact your Lexus dealer.
■Charging the 12-volt battery
 P.374
■After the 12-volt battery has discharged 
or when the terminal has been removed 
and installed during exchange, etc.
The gasoline engine may not stop even if 
the vehicle is being driven by the hybrid bat-
tery (traction battery).  If this continues for a 
few days, contact your Lexus dealer. 

2494-6. Driving tips

Driving
Control and maintain the vehicle at a 
constant speed. 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 
regenerated when slowing down.
Use the air conditioning only when 
necessary. Doing so can help reduce 
excessive gasoline consumption. 
In summer: When the ambient tem-
perature is high, use the recirculated 
air mode. Doing so will help to reduce 
the burden on the air conditioning sys-
tem and reduce fuel consumption as 
well. 
In winter: Because the gasoline engine 
will not automatically cut out until it and 
the interior of the vehicle are warm, it 
will consume fuel. Also, fuel consump-
tion can be improved by avoiding over-
use of the heater.
Make sure to check the tire inflation 
pressure frequently. Improper tire infla-
tion pressure can cause poor fuel 
economy. 
Also, as snow tires can cause large 
amounts of friction, their use on dry 
roads can lead to poor fuel economy. 
Use tires that are appropriate for the 
season. Carrying heavy luggage will lead to 
poor fuel economy. Avoid carrying 
unnecessary luggage.
 Installing a large 
roof rack will also cause poor fuel 
economy.
Since the gasoline engine starts up and 
cuts out automatically when cold, 
warming up the engine is unnecessary. 
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess 
fuel consumption.

warm or cool air is ready to flow immedi-
ately after the automatic mode switch is 
pressed or “AUTO” is selected.
Cool air may blow around the upper body 
even when the heater is on due to sunlight.
■Windshield fog detection function
When automatic mode is set, the humidity 
sensor detects fog on the windshield and 
controls the air conditioning system to pre-
vent fog.
■Automatic mode for air intake control
In automatic mode, the system detects 
exhaust gas and other pollutants and auto-
matically switches between outside air and 
recirculated air modes.
When the dehumidification function is off, 
and the fan is operating, turning automatic 
mode on will activate the dehumidification 
function.
To turn on the “DUAL” mode, perform 
any of the following procedures:
