Conditions under which the BSM func tion may not function correctly●
The BSM function may not detect vehicles correctly in the following situations:
• When the sensor is misaligned due to a strong impact to the sensor or its surround-
ing area
• When mud, snow, ice, a sticker, etc. is covering the sensor or surrounding area on
the rear bumper
• When driving on a road surface that is wet with standing water during bad weather,
such as heavy rain, snow, or fog
• When multiple vehicles are approaching wi th only a small gap between each vehicle
• When the distance between your vehicle and a following vehicle is short
• When there is a significant difference in speed between your vehicle and the vehicle
that enters the detection area
• When the difference in speed between your vehicle and another vehicle is changing
• When a vehicle enters a detection area traveling at about the same speed as your
vehicle
• As your vehicle starts from a stop, a vehicle remains in the detection area
• When driving up and down consecutive steep in clines, such as hills, dips in the road,
etc.
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces

in an adjacent lane is far away from your vehicle
• When a bicycle carrier or other accessory is installed to the rear of the vehicle
• When there is a significant difference in height between your vehicle and the vehicle
that enters the detection area
• Immediately after the BSM function is turned on ●
Instances of the BSM function unnecessarily detecting a vehicle and/or object may
increase in the following situations:

ing area
• When the distance between your vehicle and a guardrail, wall, etc. that enters the
detection area is short
• When driving up and down consecutive steep in clines, such as hills, dips in the road,
etc.

Any of the following conditions may result in an accident which could cause death or seri-
ous injury: ■
The Multi Terrain 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 a wet or slick road.■
Stopping distance when the Multi Terrain ABS is operating may exceed that of nor-
mal conditions
The Multi Terrain ABS is not designed to shorten the vehicle’s stopping distance.
Always maintain a safe distance from the vehicl e in front of you, especially in the follow-
ing 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 roads■
Active TRAC may not operate effectively when
Directional control and power may not be achievable while drivin g on slippery road
surfaces, even if the Acti ve TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost. ■
If the hill-start assist contro l does not operate effectively
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 in ice. ■
When Active TRAC, VSC and Trailer Sway Control are off
Be especially careful and drive at a speed ap propriate to the road conditions. As these
are systems to help to ensure vehicle stability and driving force, do not turn off Active

Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total load capac-
ity. In addition, make sure that the tires are inflated to the specified tire pressure level.
The Multi Terrain ABS, Active TRAC, VSC an d Trailer Sway Control will not function
correctly if different tires are fitted on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels. ■
Handling of tires and suspension
Using tires with any kind of problem or modi fying the suspension will affect the driving
assist systems, and may caus e the system to malfunction.■
Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situations.
Depending on many factors such as the condit ions of the vehicle, trailer, road surface,
and driving environment, the Trailer Sway Co ntrol system may not be effective. Refer to
your trailer owner’s manual for information on how to tow your trailer properly. ■
If trailer sway occurs
Observe the following precautions.
Failing to do so may caus e death or serious injury.●
Firmly grip the steering wh eel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel. ●
Begin releasing the accelerator pedal i mmediately but very gradually to reduce
speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle and trailer
should stabilize. (  P. 2 0 1 )
