NOTICE
■How to use the camera
●The parking assist monitor may not operate properly in the following cases.
• If the back of the vehicle is hit, the position and mounting angle of the camera may change.
• As the camera has a water proof construction, do not detach, disassemble or modify it. This may cause incorrect operation.
• Do not strongly rub the camera lens. If th e camera lens is scratched, it cannot
transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or glass coat to adhere to the camera. If this happens, wipe it off as soon as possible.
• If the temperature changes rapidly, such as when hot water is poured on the vehi-
cle in cold weather, the system may not operate normally.
• When washing the vehicle, do not apply intensive bursts of water to the camera or camera area. Doing so may result in the camera malfunctioning.
• When the camera is used under fluorescen t lights, sodium light or mercury light
etc., the lights and the illuminate d areas may appear to flicker.
●Do not expose the camera to strong impa ct as this could cause a malfunction.
If this happens, have the vehicle inspected by your Lexus dealer as soon as possible.

Suitable for improving the fuel economy,
because the torque corresponding to
the accelerator pedal depression
amount can be generated more
smoothly than it is in normal conditions
and the operation of the air conditioning
system (heating/cooling) will be mini-
mized.
When the driving mode select switch is
turned left, the “ECO MODE” indicator
comes on in the instrument cluster.
Press the switch to change the driving mode to normal mode.
Sport mode
Use when high levels of response and feel ing are desirable, such as when driving in
mountainous regions or when overtaking.
When the driving mode select switch is turned right, the “SPORT MODE” indicator
comes on in the instrument cluster.
Press the switch to change the driving mode to normal mode.
■Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the air condi-
tioning system to enhance fuel efficiency ( P. 416, 423). To improve air conditioning
performance, adjust the fan speed or turn off Eco drive mode.
■Sport mode automatic deactivation

Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if the
brakes are applied while drivin
g on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the
steering wheel
◆Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road sur-
faces by controlling steering performance.
◆Hill-start assist control
Helps to prevent the vehicle from rolling backward when starting on an incline
◆PCS (Pre-Collision System) (if equipped)
P. 2 3 9
To help enhance driving safety and performance, the following systems oper-
ate automatically in response to various driving situations. Be aware, however,
that these systems are supplementary and should not be relied upon too
heavily when operating the vehicle.

CT200h_OM_OM76197U_(U)4-5. Using the driving support systems
The slip indicator light will flash while
the VSC/TRAC/ABS systems are
operating.
If the vehicle gets stuck in mud, dirt or snow, the TRAC system may reduce
power from the hybrid system to the wheels. Pressing to turn the system
off may make it easier for you to rock the vehicle in order to free it.
To turn the TRAC system off, quickly
press and release .
The “TRAC OFF” indicator light will
come on.
Press again to turn the system
back on.
■When the “TRAC OFF” indicator comes on ev
en if the TRAC OFF switch has not been
pressed
TRAC and hill-start assist control cannot be operated. Contact your Lexus dealer.
■Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC and hill-start assist
control systems
●A sound may be heard from the engine compartment when the hybrid system is
started, just after the vehicle begins to move, if the brake pedal is depressed forcefully
or repeatedly, or 1-2 minutes after the hybrid system is stopped. This sound does not
indicate that a malfunction has occurred in any of these systems.
●Any of the following condit ions may occur when the above systems are operating.
None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slig htly after the ABS is activated.
• The brake pedal may move down s lightly after the ABS is activated.

■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be heard.
This does not indicate a malfunction.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The steering
wheel may feel heavy as a result. Should this occur, refrain from excessive steering input
or stop the vehicle and turn the hybrid system off. The EPS system should return to nor-
mal within 10 minutes.
■Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will operate:
●The shift position is in a position other than P or N (when starting off forward/backward
on an upward incline).
●The vehicle is stopped.
●The accelerator pedal is not depressed.
●The parking brake is not engaged.
■Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
●Shift the shift position to P or N
●The accelerator pedal is depressed
●The parking brake is engaged.
●Approximately 2 seconds elapse after the brake pedal is released.
■Automatic reactivation of TRAC system
After turning the TRAC system off, the system will be automatically re-enabled in the fol-
lowing situations:
●When the power switch is turned off
●The TRAC will turn on when vehicle speed increases

■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as excessively
worn tires on a snow covered road).
●The vehicle hydroplanes while driving at high speed on wet or slick road.
■Stopping distance when the ABS is operat
ing may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain a
safe distance from the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes or uneven surfaces
■TRAC may not operate effectively when
Directional control and power may not be achievable while drivin g on slippery road
surfaces, even if the TRAC system is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
■When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may cause an
accident. Exercise particular care when the indicator light flashes.
■Hill-start assist control does not operate effectively when
●Do not overly rely on the hill-start assist control. The hill-start assist control may not
operate effectively on steep inclines and roads covered with ice.
●Unlike the parking brake, hill-start assist control is not intended to hold the vehicle
stationary for an extended period of time. Do not attempt to use hill-start assist con-
trol to hold the vehicle on an incline, as doing so may lead to an accident.
■When the TRAC system is turned off
Be especially careful and drive at a speed ap propriate to the road conditions. As this is
the system to help ensure vehicle stability and driving force, do not turn the TRAC sys-
tem off unless necessary.
■Replacing tires
Make sure that all tires are of the specified size and of the same brand, tread pattern
and total load capacity. In addition, make su re that the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, VSC and TRAC systems will not fu nction correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modi fying the suspension will affect the driving
assist systems, and may caus e a system to malfunction.

PCS (Pre-Collision System)
◆Pre-collision seat belts (front seat belts only)
If the pre-collision sensor detects that a collision is unavoidable, the pre-colli-
sion system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses con-
trol of the vehicle. (
P. 3 3 )
However, when the VSC system is disabled, the system will not operate in the
event of skidding.
◆Pre-collision brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to ho w strongly the brake pedal is depressed.
◆Pre-collision braking
When there is a high possibility of a frontal collision, the system warns the
driver using a warning light, warning di splay and buzzer. If the system deter-
mines that a collision is unavoidable, the brakes are automatically applied to
reduce the collision speed. Pre-collisio n braking can be disabled using the
pre-collision braking off switch.
Pre-collision braking disabled
Pre-collision braking enabled
The “PCS” warning light will turn on
when pre-collision braking is dis-
abled.
: If equipped
When the radar sensor detects possibility of a frontal collision, the pre-colli-
sion system such as the brakes and se at belts are automatically engaged to
lessen impact as well as vehicle damage.
