2017 Lexus CT200h warning

CT200h_OM_OM76215U_(U)4-5. Using the driving support systems
When your vehicle is too close to a vehicle ahead, and sufficient automatic
deceleration via the Dynamic radar cruise control is not possible, the display will
flash and the buzzer will sound to alert th
e driver. An example of this would be if
another driver cuts in front of you while you are following a vehicle. Apply the
brakes to ensure an appropriate vehicle-to-vehicle distance.
■Warnings may not occur when
In the following instances, there is a po ssibility that the warnings will not occur:
●When the speed of the vehicle ahead matches or exceeds your vehicle
speed
●When the vehicle ahead is traveling at an extremely slow speed
●Immediately after the cruise control speed was set
●At the instant the accelerator is applied
Constant speed control mode differs from vehicle-to-vehicle distance control
mode. When constant speed control mode is selected, your vehicle will maintain
a set speed regardless of whether or not there are other vehicles in the lane
ahead.
Press the “ON-OFF” button to acti-
vate the cruise control.
Press the button again to deactivate the
cruise control.
Switch to constant speed control
mode.
(Push the lever forward and hold for
approximately one second.)
Cruise control indicator will come on.
When in constant speed control mode, to return to vehicle-to-vehicle distance con-
trol mode, push the lever forward agai n and hold for approximately 1 second.
After the desired speed has been set, it is not possible to return to vehicle-to-vehicle
distance control mode.
If the power switch is turned off and then turned to ON mode again, the vehicle will
automatically return to vehicle-to-vehicle distance control mode.

■Dynamic radar cruise control can be set when
●The shift position is in D.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed resumes. How-
ever, during vehicle-to-vehicle distance control mode, the vehicle speed may decrease
below the set speed in order to maintain the distance to the vehicle ahead.
■Set speed
The set speed may be unsustainable depending on driving circumstances.
■Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the following situ-
ations:
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●Enhanced VSC is activated.
●The sensor cannot operate correctly because it is covered in some way.
●The windshield wipers are oper ating at high speed. (when the wiper switch is set to the
“AUTO” mode or the high speed wiper operation position).
If vehicle-to-vehicle distance control driving is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact your Lexus dealer.
■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h) below the set vehi-
cle speed.
At this time, the memorized set speed is not retained.
●Vehicle speed falls below approximately 25 mph (40 km/h).
●Enhanced VSC is activated.
■Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle dis-
tance control operates properly. (Some obstructions, such as snow, ice and plastic
objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is cancel ed if an obstruction is detected.
■Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or to inform
the driver of the need for caution while driving. (P. 5 4 2 )

■To avoid inadvertent cruise control activation
Switch the cruise control off using th
e “ON-OFF” button when not in use.
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an accident result-
ing in death or serious injury.
●Roads where there are pedestrians, cyclers, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as thos e covered with rain, ice or snow
●On steep downhills, or where there are sudden changes between sharp up and down
gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
●At entrances to expressways
●When weather conditions are bad enough that they may prevent the sensors from
detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
●When an approach warning buzzer is heard often
●During emergency towing

■When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the brake pedal
when deceleration of the system is insufficient or operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the approach
warning ( P. 196) will not be activated, which may lead to an accident resulting in
death or serious injury.
●Vehicles with small rear ends (tra ilers with no load on board etc.)
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the same lane

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 5 )
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.

■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the sensors
being unable to detect obstacles, the pre-collision syst em will be automatically disabled.
In this case, the system will not activate even if there is a collision possibility.
■When there is a malfunction in the system, or if the system is temporarily unusable
Warning lights and/or warning mess ages will turn on or flash. (P. 535, 542)

■Limitations of the pre-collision system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Do not use the pre-collisions system instea d of normal braking operations under any
circumstances. This system will not prevent collisions or lessen damage or injuries in all
cases. Do not overly rely on this system. Failu re to do so may cause an accident, result-
ing in death or serious injury.
This system has been designed to help av oid and reduce the impact of collisions. How-
ever, the system operates differently depending on the situation ( P. 243, 244). As a
result, the same level of performance may not be expected in all cases. Also, the pre-
collision’s brakes may not operate if the driver is depressing the brake pedal or turning
the steering wheel, as the system will dete rmine such conditions as collision avoidance
operations.
