When using the Lexus parking assist monitor system
The parking assist monitor is a supplemental device intended to assist the driver when
backing up. When backing up, be sure to chec k visually behind and all around the vehi-
cle before proceeding.
Observe the following precautions to avoid an accident that could result in death or
serious injuries. ●
Never depend on the parking assist monitor entirely when backing up. The image
and the position of the guide lines displaye d on the screen may differ from the actual
state.
Use caution, just as you would when backing up any vehicle. ●
Be sure to back up slowly, depressing the brake pedal to control vehicle speed. ●
If you seem likely to hit nearby vehicles, obstacles, people or mount the shoulder,
depress the brake pedal to stop the vehicle. ●
The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to traffic condi-
tions, road surface conditions, vehicle condit ion, etc. when parking. It is necessary to
be fully aware of this before using the parking assist system. ●
When parking, be sure to check that the par king space will accommodate your vehi-
cle before maneuvering into it. ●
Do not use the parking assist monitor in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emergency tires
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slopes. ●
In low temperatures, the screen may darken or the image may become faint. The
image could distort when the vehicle is moving, or you may become unable to see the
image on the screen. Be sure to check dire ct visually and with the mirrors all around
the vehicle before proceeding. ●
If the tire sizes are changed, the position of the guide lines displayed on the screen
may change. ●
The camera uses a special lens. The dist ances between objects and pedestrians that
appear in the image displayed on the screen will differ from the actual distances.
(  P. 3 4 7 ) ●
Estimated course line display mode: If the st eering wheel is straight and the vehicle
width guide lines and the estimated course li nes are not in alignment, have the vehicle
inspected by your Lexus dealer.

How to use the camera ●
The parking assist monitor may not oper ate 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.
• When cleaning the camera lens, flush the camera with a large quantity of water
and wipe it with a soft and wet cloth. St rongly rubbing the camera lens may cause
the camera lens to be scratched and unable to 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.

Reactivation of the TRAC system linked to vehicle speed
When only the TRAC system is turned off, the TRAC system will turn on when vehicle
speed increases. However, when TRAC, VS C and Trailer Sway Control systems are
turned off, the systems will not turn on even when vehicle speed increases.■
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 engine of f. The EPS system should return to normal
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 lever 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: ●
The shift lever is moved to P or N. ●
The accelerator pedal is depressed. ●
The parking brake is engaged. ●
Approximately 2 seconds elapse after the brake pedal is released.
WA R N I N G ■
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 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 ■

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 VSC/Trailer Sway Control 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 TRAC/VSC/Trailer Sway Control systems are turned off
Be especially careful and drive at a speed ap propriate to the road conditions. As these
are the systems to help ensure vehicle st ability and driving force, do not turn the
TRAC/VSC/Trailer Sway Control 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, TRAC, VSC and Trailer Sway Control systems will not function 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.■
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 1 5 )
