When stopped/during start off
The gasoline engine stops* when the vehicle is stopped. During start
off, the electric motor (traction motor) drives the vehicle. At slow
speeds or when traveling down a gentle slope, the engine is stopped*
and the electric motor (traction motor) is used.
When shift position is in N, the hybrid battery (traction battery) is not
charged. When the vehicle is stopped, always put the shift position to P.
Also, even in heavy traffic conditions, drive the vehicle in D or B.
*: When the hybrid battery (traction battery) requires charging or the engine is
warming up, etc., the gasoline engine will not automatically stop. (P. 79)
During normal driving
The gasoline engine is predominantly used. The electric motor (trac-
tion 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 braking)
The wheels operate the electric motor as a power generator, and the
hybrid battery (traction battery) is charged.
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 B.
The brake pedal is depressed while driving with the shift position in D or B.

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 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 will slowly discharge. For this rea-
son, 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 start the hybrid system, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
Charging the 12-volt battery
P. 626
After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is being driven by the
hybrid battery (traction battery). If this continues for a few days, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional. The EV indicator comes on when the vehi-
cle is driven using only the electric motor
(traction motor) or the gasoline engine is
stopped.

Triggering of the alarm
The alarm may be triggered in the following situations:
(Stopping the alarm deactivates the alarm system.)
Alarm-operated door lock
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. 650)
The doors are unlocked using the mechan-
ical key.
A person inside the vehicle opens a door
or hood.
The 12-volt battery is recharged or
replaced when the vehicle is locked. (P.
625)
NOTICE
To ensure the system operates correctly
Do not modify or remove the system. If modified or removed, the proper oper-
ation of the system cannot be guaranteed.

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. 589)
As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery when
necessary. (P. 530)
• The smart entry & start system or the wireless remote control does not oper-
ate.
• 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
• Induction cookers
• Table lamps

Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional for details.
If a wrong key is used
The key cylinder rotates freely to isolate inside mechanism.

Driving
CT200h_OM_OM76102E_(EE)
About engine braking
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
• When the vehicle is driven at high speeds, compared to ordinary gasoline-
fueled vehicles, the engine braking deceleration is felt less than that of other
vehicles.
• The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, select the D position.
When driving with cruise control or dynamic radar cruise control activated
Even if switching the driving mode to sport mode with the intent of enabling
engine braking, engine braking will not activate because cruise control or
dynamic radar cruise control will not be canceled.
Automatically P position selection function
When the shift position is in a position other than P, pressing the power switch
with the vehicle stopped completely will cause the shift position to change to P
automatically, and then the power switch will turn off.
If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-volt
battery in this situation. (P. 623)
After recharging/reconnecting the 12-volt battery

Customization
Settings (e.g. Reverse warning buzzer) can be changed.
