Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate 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.
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.
TRC (Traction Control)
Maintains drive power and prevents the rear wheels from spinning
when starting the vehicle or accelerating on slippery roads.
Hill-start assist control (vehicles with an automatic transmis-
sion)
Helps to prevent the vehicle from rolling backward when starting
on an incline or slippery slope.
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel.
PCS (Pre-Crash Safety System) (if equipped)
P. 230
VDIM (Vehicle Dynamics Integrated Management)
Provides integrated control of the ABS, brake assist, TRC, VSC,
hill-start assist control, and EPS systems.
Helps to maintain vehicle stability when swerving on slippery road

When driving
IS250/220d/200d_EE
Sounds and vibrations caused by the ABS, brake assist, VSC, TRC and hill-
start assist control systems
A sound may be heard from the engine compartment if the brake pedal is
depressed repeatedly when the engine is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
Any of the following conditions 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 slightly when the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
Hill-start assist control is operational when
The shift lever is in the D or S position.
The brake pedal is not depressed.
The vehicle rolls backward.
EPS operation sound
When the steering wheel operates, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
Reduced effectiveness of EPS
The effectiveness of EPS 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 engine OFF. The
system should return to normal within 10 minutes.
If the slip indicator comes on
It may indicate a malfunction in the VSC, TRC or hill start assist control
function. Contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.

Guidance
Your vehicle will handle differently when towing a trailer. In order
to avoid accident, death or serious injury, keep the following in
mind when towing:
Checking connections between trailer and lights
Stop the vehicle and check the operation of the connection
between the trailer and lights after driving for a brief period as
well as before setting off.
Practicing driving with a coupled trailer
Get the feel for turning, stopping and reversing with the trailer
coupled by practicing in an area with no or light traffic.
When reversing with a coupled trailer, hold the section of the
steering wheel nearest to you and rotate clockwise to turn the
trailer left or counterclockwise to turn right. Always rotate
gradually to prevent steering error. Have someone guide you
when reversing to lessen the risk of accident.
Increasing vehicle-to-vehicle distance
At a speed of 10 km/h (6 mph), the distance to the vehicle run-
ning ahead of you should be equivalent to or greater than the
combined length of your vehicle and trailer. Avoid sudden brak-
ing that may cause skidding. Otherwise, the vehicle may spin
out of control. This is especially true when driving on wet or
slippery road surfaces.
Sudden acceleration/steering input/cornering
Executing sharp turns when towing may result in the trailer col-
liding with your vehicle. Decelerate well in advance when
approaching turns and take them slowly and carefully to avoid
sudden braking.
