Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained 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 S.
The brake pedal is depressed while driving with the shift position in D or S.
EV indicator
Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically 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 bat-
tery does not need to be charged from an outside source. However, if the
vehicle is left parked for a long time the hybrid battery will slowly dis-
charge. For this reason, be sure to drive the vehicle at least once every few
months for at least 30 minutes or 16 km (10 miles). If the hybrid battery
becomes fully discharged and you are unable to jump-start the vehicle with
the 12-volt battery, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
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 discharging the battery.
Charging the 12-volt battery
P. 9 1 2 The EV indicator comes on when the
vehicle is driven using only the electric
motor (traction motor) or the gasoline
engine is stopped.

When the alarm is operating, the doors are locked automatically to prevent
intruders.
Do not leave the key inside the vehicle when the alarm is operating, and
make sure the key is not inside the vehicle when recharging or replacing the
12-volt battery.
Customization
The alarm can be set to deactivate when the mechanical key is used to
unlock.
(Customizable features: P. 942)
The doors are unlocked using the
mechanical key.
A person inside the vehicle opens a
door, the trunk or hood.
The 12-volt battery is recharged or
replaced when the vehicle is locked.

The meters and display illuminate when
The power switch is in ON mode.
Instrument panel brightness adjustment
The instrument panel brightness levels when the tail lights are on and off can
be adjusted individually. However, when the surroundings are bright (day-
time, etc.), turning on the tail lights will not change the instrument panel
brightness.
Limitation of brightness adjustment
The brightness of the instrument panel lights 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 either the brightest or
darkest setting, the automatic adjustment will not be performed.
Hybrid System Indicator
Hybrid System Indicator is displayed when the driving mode is other than
the sport mode.
By keeping the indicator needle within Eco 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 created by the movement of the vehicle into electrical energy. Charge area
Shows regenerative charging.

Shows that gasoline engine power is
not being used very often.
The gasoline engine will automatically
stop and restart under various condi-
tions.

Electronic key battery depletion
The standard battery life is 1 to 2 years. (The card key battery life is about a
year and a half.)
If the battery becomes low, an alarm will sound in the cabin when the
hybrid system stops. (P. 867)
As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms
indicate that the electronic key battery may be depleted. Replace the battery
when necessary. (P. 777)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
To avoid serious deterioration, do not leave the electronic key within 1 m (3
ft.) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
•Table lamps
• Induction cookers
When the electronic key battery is fully depleted
