Situations in which EV drive mode cannot be turned on
It may not be possible to turn EV drive mode on in the following situations.
If it cannot be turned on, a buzzer will sound and a message will be shown
on the multi-information display.
The temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high
speeds, etc.
The temperature of the hybrid system is low.
The vehicle has been left in temperatures lower than about 0 C (32 F)
for a long period of time etc.
The gasoline engine is warming up.
The hybrid battery (traction battery) is low.
An “Energy monitor” display of level 3 or lower may indicate a low bat-
tery level. (P. 4 9 )
Vehicle speed is high.
The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
The windshield defogger is in use.
Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is started while the gasoline engine is cold, the gasoline
engine will start automatically after a short period of time in order to warm
up. In this case, you will become unable to switch to EV drive mode.
After the hybrid system has started and the “READY” indicator has illumi-
nated, press the EV drive mode switch before the gasoline engine starts to
switch to EV drive mode.

Automatic cancellation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically
restart in the following situations. When EV drive mode is canceled, a
buzzer will sound and the EV drive mode indicator will flash and go off.
The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the “Energy monitor” display is
level 2 or lower. (P. 4 9 )
Vehicle speed becomes high.
The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
When it is possible to inform the driver of automatic cancelation in advance,
a prior notice screen will appear on the multi-information display.
Possible driving distance when driving in EV drive mode
In EV drive mode, it is possible to drive up to about 1 km (1/2 mile) if driv-
ing at a speed of about 45 km/h (28 mph) or less. (The distance that is possi-
ble depends on the hybrid battery [traction battery] level and driving
conditions.)
Fuel economy
CT200h is designed to achieve the best possible fuel economy during nor-
mal driving (using the gasoline engine and electric motor [traction motor]).
Driving in EV drive mode more than necessary may lower fuel economy.
CAUTION
While driving
When driving in EV drive mode, pay special attention to the area around the
vehicle. Because there is no engine noise, pedestrians, people riding bicy-
cles or other people and vehicles in the area may not be aware of the vehicle
starting off or approaching them, so take extra care while driving.

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 gaso-
line-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. 633)
Sport mode automatic deactivation
Sport mode is automatically deactivated if the “POWER” switch is turned
off after driving in sport mode.
After recharging/reconnecting the 12-volt battery
P. 5 1 1
Customization
Settings (e.g. Reverse warning buzzer) can be changed.
(Customizable features P. 667)

NOTICE
Hybrid battery (traction battery) charge
If the shift position is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid leaving the N
position selected for an extended period of time.
Situations where P position control system malfunctions are possible
If any of the following situations occurs, P position control system malfunc-
tions are possible.
Immediately stop the vehicle in a safe place on level ground, apply the park-
ing brake, and then contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
When the “P LOCK MALFUNCTION” warning message appears on the
multi-information display. (P. 580)
When the shift position indicator remains off.
Notes regarding shift lever and P position switch operation
Avoid repeatedly operating the shift lever and P position switch in quick
succession.
The system protection function may activate and it will not be temporarily
possible to shift the shift position other than P. If this happens, please wait
for a while before attempting to change the shift position again.

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 driv-
ing 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.
