Regenerative braking
In the following situations, ki netic energy is converted to electric energy and decelera-
tion force can be obtained in conjunction with the recharging of the hybrid battery (trac-
tion battery). ●
The accelerator pedal is released while driving with the shift lever in D or S.●
The brake pedal is depressed while driv ing with the shift lever in D or S.■

■
Conditions in which the ga soline engine may not stop
The gasoline engine starts and stops automati cally. However, it may not stop automati-
cally in the following conditions: ●
During gasoline engine warm-up ●
During hybrid battery (traction battery) charging ●
When the temperature of the hybrid battery (traction battery) is high or low ●
When the heater is switched on ■
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 ou tside source. However, if the vehicle is left parked for a
long time the hybrid battery (traction batter y) will slowly discharge. For this reason, be
sure to drive the vehicle at least once every few months for at least 30 minutes or 10
miles (16 km). If the hybrid battery (traction battery) beco mes fully discharged and you
are unable to start the hybrid sy stem, contact your Lexus dealer. ■
Charging the 12-volt battery
→ P. 698 ■
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 battery
(traction battery). If this continues fo r a few days, contact your Lexus dealer.The EV indicator comes on when the vehicle is
driven using only the el ectric motor (traction
motor) or the gasoline engine is stopped.

Driving
RX450h_RX450hL _U_OM48F85U◆ Delays
Repeated acceleration and deceleration, as well as long waits at traffic lights,
will lead to bad fuel economy. Check traffic reports before leaving and avoid
delays as much as possible. When drivin g in a traffic jam, gently release the
brake pedal to allow the vehicle to move forward slightly while avoiding over-
use of the accelerator pedal. Doing so can help control excessive gasoline
consumption.
◆ Highway driving
Control and maintain the vehicle at a co nstant speed. Before stopping at a toll
booth or similar, allow plenty of ti me to release the accelerator and gently
apply the brakes. A greater amount of electrical energy can be regenerated
when slowing down.
◆ Air conditioning
Use the air conditioning only when necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recirculated air
mode. Doing so will help to reduce the burden on the air conditioning system
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 con-
sumption can be improved by av oiding overuse of the heater.
◆ Checking tire inflation pressure
Make sure to check the tire inflation pr essure frequently. Improper tire infla-
tion pressure can cause poor fuel economy.
Also, as snow tires can cause large amou nts of friction, their use on dry roads
can lead to poor fuel economy. Use ti res that are appropriate for the season.
◆ Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack will also cause poor fuel
economy.
◆ Warming up before driving
Since the gasoline engine starts up an d cuts out automatically when cold,
warming up the engine is unnecessary. Moreover, frequently driving short dis-
tances will cause the engine to repeated ly warm up, which can lead to excess
fuel consumption.
