321-1. Hybrid system
■
Regenerative braking
In the following situations, kinetic energy is converted to electric energy and decel-
eration force can be obtained in conjunction with the recharging of the hybrid bat-
tery (traction battery). ●
The accelerator pedal is released. ●
The brake pedal is depressed with the shift lever in D or S.■
Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. 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 batt ery (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 outside source. However, if the vehicle is
left parked for a long time the hybrid ba ttery will slowly discharge. For this rea-
son, be sure to drive the vehicle at least once every few months for at least 30
minutes. If the hybrid battery becomes fully discharged and you are unable to
jump-start the vehicle with the 12-volt battery, contact your Lexus dealer. ●
If the shift lever is in N, the hybrid battery (traction battery) will not be charged.
Always put the shift lever in P when the vehicle is stopped. When driving in
heavy traffic, operate the vehicle with the shift lever in D or S to avoid discharg-
ing the battery.■
After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not st op even if the vehicle is running on the hybrid battery
(traction battery). If this continues for a few days, contact your Lexus dealer.

4911-1. Hybrid system
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.
