NOTICE
Hybrid battery air vent
Do not put foreign objects near the air vent. The hybrid battery (traction
battery) may overheat and be damaged.
Clean the air vent regularly to prevent the hybrid battery (traction battery)
from overheating.
Do not wet or allow foreign substances to enter the air vent as this may
cause a short circuit and damage the hybrid battery (traction battery).
Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the bat-
tery may be damaged. Have the vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.

CT200h_OM_OM76067E_(EE)
Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is rec-
ommended:
For the first 300 km (200 miles):
Avoid sudden stops.
For the first 2000 km (1200 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive at a constant speed for extended periods.
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the avail-
ability of the correct fuel. (P. 6 5 3 )
For efficient use
Shift the shift position to D when driving.
In the N position, the gasoline engine operates but electricity cannot be
generated. The hybrid battery (traction battery) will discharge, requiring
unnecessary engine power to recharge.
Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and
deceleration will make more effective use of the electric motor (traction
motor) without having to use gasoline engine power.
Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving
with the accelerator pedal slightly released.
Shift the shift position to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift position in the N position for an extended period of
time may discharge the hybrid battery (traction battery). The vehicle
cannot run if the hybrid battery (traction battery) is discharged.

EV drive mode
In EV drive mode, the electric motor (traction motor), powered by the
hybrid battery (traction battery), is used to drive the vehicle.
This mode allows you to drive in residential areas late at night, or in
indoor parking lots etc. without concern for noises and exhaust gas
emissions.
Turns EV drive mode on/off
When EV drive mode is
turned on, the EV drive mode
indicator will come on.
Pressing the switch when in
EV drive mode will return
the vehicle to normal driving
(using the gasoline engine

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.

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.

Maintenance and care
CT200h_OM_OM76067E_(EE)
Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year
to maintain the quality of the vehicle’s interior.
Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a
sponge or brush to apply the foam. Rub in overlapping circles. Do not use
water. Wipe dirty surfaces and let them dry. Excellent results are obtained
by keeping the carpet as dry as possible.
Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
CAUTION
Water in the vehicle
Do not splash or spill liquid in the vehicle, such as on the floor, in the
hybrid battery (traction battery) air vents, and in the luggage compart-
ment.
Doing so may cause the hybrid battery, electrical components, etc. to mal-
function or catch fire.
Do not get any of the SRS components or wiring in the vehicle interior
wet.
(P. 153)
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.
Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect
off the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.
