◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if the
brakes are applied while driving 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
◆VSC+ (Vehicle Stability Control+)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road sur-
faces by controlling steering performance.
◆TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
◆Hill-start assist control
Prevents the vehicle from rolling backward when starting on an incline or slip-
pery slope
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the
steering wheel
Driving assist systems
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.

IS250_EE(OM53C51E)
CAUTION
■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 roads.
■Stopping distance when the ABS is operating 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
■TRC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road
surfaces, even if the TRC system is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
■Hill- start assist control does not operate effectively when
●Do not overly rely on hill-start assist control. 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 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.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As these
are the systems to help ensure vehicle stability and driving force, do not turn the TRC/
VSC systems off unless necessary.
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire infla-
tion pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires are installed
on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the driving
assist systems, and may cause a system to malfunction.

CAUTION
■Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of the vehicle
rear bumper respectively. Observe the following to ensure the Blind Spot Monitor can
function correctly.
●Do not subject the sensor or surrounding area on the bumper to a strong impact. If
the sensor moves even slightly off position, the system may malfunction and vehicles
that enter the detection area may not be detected. If the sensor or surrounding area is
subject to a strong impact, always have the area inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor or surrounding area on the
bumper.
●Do not modify the sensor or surrounding area on the bumper.
●Do not paint the sensor or surrounding area on the bumper.
●Keep the sensor and its surrounding area on
the bumper clean at all times.

The Blind Spot Monitor function uses radar sensors to detect vehicles that are
traveling in an adjacent lane in the area that is not reflected in the outside rear
view mirror (the blind spot), and advises the driver of the vehicles existence via
the outside rear view mirror indicator.
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to:
Approximately 3.5 m (11.5 ft.) from
the side of the vehicle
The first 0.5 m (1.6 ft.) from the side of
the vehicle is not in the detection area
Approximately 3 m (9.8 ft.) from the
rear bumper
Approximately 1 m (3.3 ft.) forward
of the rear bumper

CAUTION
■Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The Blind Spot Monitor function is a supplementary function which alerts the driver
that a vehicle is present in the blind spot. Do not overly rely on the Blind Spot Monitor
function. The function cannot judge if it is safe to change lanes, therefore over reliance
could cause an accident resulting in death or serious injury.
According to conditions, the system may not function correctly. Therefore the driver’s
own visual confirmation of safety is necessary.

The Rear Crossing Traffic Alert functions when your vehicle is in reverse. It can
detect other vehicles approaching from the right or left rear of the vehicle. It uses
radar sensors to alert the driver of the other vehicle’s existence through flashing
the outside rear view mirror indicators and sounding a buzzer.

■Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The Rear Crossing Traffic Alert function is only an assist and is not a replacement for
careful driving. Driver must be careful when backing up, even when using Rear Cross-
ing Traffic Alert function. The driver’s own visual confirmation of behind you and your
vehicle is necessary and be sure there are no pedestrians, other vehicles etc. before
backing up. Failure to do so could cause death or serious injury.
According to conditions, the system may not function correctly. Therefore the driver’s
own visual confirmation of safety is necessary.

●The shift lever is in R.
●Vehicle speed is less than approximately 8 km/h (5 mph).
●Approaching vehicle speed is between approximately 8 km/h (5 mph) and 28 km/h
(18 mph).
