Operation of each component
■Alarms and warning messages
An alarm sounds and warning message displays shown on the multi-information display
are used to protect against unexpected accidents or theft of the vehicle resulting from
erroneous operation. When a warning message is displayed, take appropriate measures
based on the displayed message. (→ P. 5 3 4 )
When only an alarm sounds, circumstances and correction procedures are as follows.
■Battery-saving function
The battery-saving function will be activated in order to prevent the electronic key bat-
tery and the 12-volt battery from being discharged while the vehicle is not in operation
for a long time.
●In the following situations, the smart access system with push-button start may take
some time to unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of the outside
of the vehicle for 10 minutes or longer.
• The smart access system with push-button start has not been used for 5 days or longer.
●If the smart access system with push-button start has not been used for 14 days or
longer, the doors cannot be unlocked at any doors except the driver’s door. In this case,
take hold of the driver’s door handle, or use the wireless remote control or the mechan-
ical key, to unlock the doors.
■Conditions affecting operation
The smart access system with push-button start, wireless remote control and immobilizer
system use weak radio waves. In the following situations, the communication between the
electronic key and the vehicle may be affected, preventing the smart access system with
push-button start, wireless remote control and immobilizer system from operating prop-
erly. (Ways of coping: →P. 5 5 9 )

Operation of each component
●If the electronic key is inside the vehicle and a door handle becomes wet during a car
wash, a message may be shown on the multi-information display and a buzzer will
sound outside the vehicle. To turn off the alarm, lock all the doors.
●The lock sensor may not work properly if it comes into contact with ice, snow, mud, etc.
Clean the lock sensor and attempt to operate it again, or use the lock sensor on the
lower part of the door handle.
●A sudden approach to the effective range or door handle may prevent the doors from
being unlocked. In this case, return the door handle to the original position and check
that the doors unlock before pulling the door handle again.
●If there is another electronic key in the de tection area, it may take slightly longer to
unlock the doors after the door handle is gripped.

WA R N I N G
■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pr
e-collision system is intended to assist the
driver in avoiding collisions through the process of LOOK-JUDGE-ACT. There are
limits to the degree of assistance the system can provide, so please keep in mind the
following important points.
●Assisting the driver in watching the road
The pre-collision system is only able to detect obstacles directly in front of the vehicle,
and only within a limited range. It is not a mechanism that allows careless or inatten-
tive driving, and it is not a system that can as sist the driver in low-visibility conditions. It
is still necessary for the driver to pay close attention to the vehicle’s surroundings.
●Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data available to
the pre-collision system is that from obstacles it has detected directly in front of the
vehicle. Therefore, it is absolutely necessary for the driver to remain vigilant and to
determine whether or not there is a possibility of collision in any given situation.
●Assisting the driver in taking action
The pre-collision system’s braking assist feature is designed to help reduce the sever-
ity of a collision, and so on ly acts when the system has judged that a collision is
unavoidable. This system by itself is not capable of automatically avoiding a collision
or bringing the vehicle to a stop safely. For this reason, when encountering a danger-
ous situation the driver must take direct and immediate action in order to ensure the
safety of all involved.
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
●When water or snow thrown up by the surrounding vehicles hinders the functioning
of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage com-
partment etc.)
●Vehicles that cut in suddenly
●Vehicles with small rear ends (trailers with no load on board etc.)
●Motorcycles traveling in the same lane
■Handling the radar sensor
Observe the following to ensure the pre-collision system can function effectively:
●Keep the sensor and front grille cover clean at all times.
Clean the sensor and front grille cover with a soft cloth so you do not mark or dam-
age them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may become inaccurate or
malfunction. If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by your Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to th e sensor, grille cover or surrounding area.
●Do not modify or paint the sensor and grille cover.

5608-2. Steps to take in an emergency
CT200h_OM_OM76174U_(U)
Depress the brake pedal.
Touch the Lexus emblem side of the
electronic key to the power switch.
If any of the doors is opened or closed
while the key is being touched to the
switch, an alarm will sound to indicate
that the start function cannot detect the
electronic key.
Press the power switch within 10 seconds of the buzzer sounding, keeping the
brake pedal depressed.
In the event that the hybrid system still cannot be operated, contact your Lexus
dealer.
■Stopping the hybrid system
Set the parking brake, shift the shift position to P and press the power switch as you nor-
mally do when stopping the hybrid system.
■Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the electronic
key battery be replaced immediately when the battery is depleted. ( →P. 5 0 2 )
■Changing power switch modes
Within 10 seconds of the buzzer sounding, release the brake pedal and press the power
switch.
The hybrid system does not start and mode s will be changed each time the switch is
pressed. ( →P. 1 5 7 )

When trouble arises
■Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■To prevent 12-volt battery discharge
●Turn off the headlights and the audio sy stem while the hybrid system is off.
●Turn off any unnecessary electrical components when the vehicle is running at a low
speed for an extended period, such as in heavy traffic.
■When the 12-volt battery is removed or discharged
●The hybrid system may not start. (→P. 4 8 6 )
●If the 12-volt battery discharges while the shift position is in P, it may not be possible to
shift the shift position to other positions. In this case, the vehicle cannot be towed with-
out lifting both front wheels because the front wheels will be locked. ( →P. 5 2 2 )
●When the 12-volt battery is reconnected, start the hybrid system and confirm that the
shift position can be changed to each position using the shift position indicator.
●Make sure that the key is not inside the vehicle when recharging or replacing the 12-
volt battery. The key may be locked in the vehicle if the alarm is activated. ( →P. 7 5 )
■Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when the vehicle
is not in use, due to natural discharge and the draining effects of certain electrical appli-
ances. If the vehicle is left for a long time, the 12-volt battery may discharge, and the
hybrid system may be unable to start. (The 12-volt battery recharges automatically while
the hybrid system is operating.)
WA R N I N G
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable gas
that may be emitted from the 12-volt battery:
●Make sure each jumper cable is connected to the correct terminal and that it is not
unintentionally in contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” terminal to come
into contact with any other parts or metal surfaces in the area, such as brackets or
unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into contact with each
other.
●Do not smoke, use matches, cigarette lighters or allow open flame near the 12-volt
battery.
