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.
■ ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the br akes 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 de tects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces.
■ TRAC (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
Helps to reduce the vehicle’s rolling backward distance 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.
■VDIM (Vehicle Dynamics Integrated Management)
Provides integrated control of the ABS, brake assist, VSC, TRAC, and hill-
start assist control systems.
Helps to maintain vehicle stability when swerving on slippery road surfaces
by controlling the brakes and engine output.
When switched to SPORT driving mode, the control characteristics of the
VDIM system are altered.

When driving
CAUTION
■The ABS does not operate effectively when
●Tires with inadequate gripping ability are used.
●The vehicle hydroplanes while driving at high speed on wet or slick roads.
■Stopping distance when the ABS is operating will exceed that of normal condi-
tions
The ABS is not designed to shorten the vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in front of you in the following situations:
●When driving on dirt, gravel or snow-covered roads
●When driving over bumps in the road
●When driving over roads with potholes or roads with uneven surfaces
■TRAC may not operate effectively in some conditions
Directional control and power may not be ac hievable while driving on slippery road
surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■Hill-start assist control does not operate effectively in some conditions
Do not overly rely on the hill-start assist co ntrol. The hill-start assist control may not
operate effectively depending on the grad e of incline and on roads covered with
ice.
■If the slip indicator flashes while driving
The slip indicator flashes to indicate that ABS, VSC, TRAC or hill-start assist con-
trol is operating. Always drive carefully. Reckless driving may cause an accident.
Exercise particular care when the indicator light flashes.
■When the VSC/TRAC 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 vehicl e stability and driving force by automati-
cally controlling the brakes and engine ou tput, do not turn the VSC/TRAC systems
off unless necessary.

■Automatic retraction
Even if the active rear wing is raised manually, it will automatically retract when the
vehicle speed exceeds 16 mph (25 km/h).
(It will not rise again until the abov e mentioned trigger speed is reached.)
■When there is a malfunction in the system
“Failure of active rear wing” will be shown on the meter. ( P. 3 2 5 )
Avoid high speed driving and have the vehicle inspected by your Lexus dealer.
CAUTION
■When manually operating the active rear wing
Observe the following precautions before operating the active rear wing. Failure to
do so may result in de ath or serious injury.
●Ensure that the surrounding area is free from any foreign objects that may come
into contact with or get caught by the active rear wing.
●If there is a risk that a foreign object may become jammed during operation, stop
operation immediately or raise the active re ar wing by pressing up on the switch.
●When there are people near the active rear
wing, make sure that there is no possibility
of their clothing, personal belongings or
body parts getting caught. Children espe-
cially should be warned not to touch the
active rear wing while it is being operated.

■ Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the
system is designed to automatically call the response center. The
responding agent receives the vehicl e’s location and attempts to speak
with the vehicle occupants to asse ss the level of emergency. If the
occupants are unable to communicate, the agent automatically treats
the call as an emergency, contacts the nearest emergency services
provider to describe the situation, and requests that assistance be sent
to the location.
