1-1. Hybrid system
CT200h_OM_OM76067E_(EE)
Hybrid battery air vent
There is an air intake vent on
the side of the rear right seat-
back for the purpose of cooling
the hybrid battery (traction bat-
tery). If the vent become
blocked, the hybrid battery may
overheat, leading to a reduction
in hybrid battery output.
Emergency shut off system
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel
leakage. If the emergency shut off system activates, your vehicle
will not restart. To restart the hybrid system, contact any autho-
rized Lexus dealer or repairer, or another duly qualified and
equipped professional.

Before driving
CT200h_OM_OM76067E_(EE)
Hybrid warning message
A message is automatically displayed when a malfunction occurs
in the hybrid system or an improper operation is attempted.
If a warning message is shown
on the multi-information dis-
play, read the message and fol-
low the instructions.
(P. 578)
If a warning light comes on, a warning message is displayed, or the 12-volt
battery is disconnected
The hybrid system may not start. In that case, try to start the system again. If
the “READY” indicator does not come on, contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be
started, refuel the vehicle with at least enough gasoline to make the low fuel
level warning light (P. 575) go off. If there is only a small amount of fuel,
the hybrid system may not be able to start. (The minimum amount of fuel to
add to make the low fuel level warning light go out is about 11.8 L [3.1 gal.,
2.6 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)

When driving
CT200h_OM_OM76067E_(EE)
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.

2-1. Driving procedures
CT200h_OM_OM76067E_(EE)
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.

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-

Maintenance and care
CT200h_OM_OM76067E_(EE)
Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
Engine missing, stumbling or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air
conditioning system after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon monox-
ide leak. Drive with the windows open and have the exhaust system
checked immediately.)
Flat-looking tires, excessive tire squeal when cornering, uneven tire
wear
Vehicle pulls to one side when driven straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one side when braking
Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.
CAUTION
If your vehicle is not properly maintained
Improper maintenance could result in serious damage to the vehicle and
possible serious injury or death.
Handling of the 12-volt battery
12-volt battery posts, terminals and related accessories contain lead and lead
compounds which are known to cause brain damage. Wash your hands after
handling. (P. 508)
