Driving assist systems
To help enhance driving safety and performance, the following systems
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.
■TRAC (Traction Control)
Helps to maintain drive power and prevent the rear wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■Hill-start assist control
Helps to prevents the vehicle from rolling backwards 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, TRAC, VSC, hill-start
assist control, and EPS systems.
Maintains vehicle stability when swerving on slippery road surfaces by
controlling the brakes and engine output.
When the “SPORT” side of the F-sport mode total control switch is
pressed, “Sport” mode is activated. (→ P. 1 8 0 )
■PCS (Pre-Collision System) (if equipped)
→ P. 1 8 4

■Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC and hill-start
assist control systems
●A sound may be heard from the engine compartment 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 operat-
ing. 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 after 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 M position.
●The brake pedal is not depressed.
■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.
■Automatic deactivation of “Sport” mode
When the “ENGINE START STOP” switch is turned OFF after driving in “Sport”
mode, the mode is automatically deactivated.
■If the slip indicator comes on
It may indicate a malfunction in the VSC, TRAC or hill-start assist control system.
Contact your Lexus dealer.

CAUTION
■Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk.
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failing to do so may result in death or serious injury.
●Do not place cargo or luggage in or on the following locations as the item may
get under the brake or accelerator pedal and prevent pedals from being
depressed properly, block the driver's vision, or hit the driver or passengers,
causing an accident.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• Package tray (behind the rear seatback)
• Instrument panel
•Dashboard
●Secure all items in the occupant compartment, as they may shift and injure some-
one during sudden braking, sudden swerving or an accident.
■Luggage capacity and distribution
Observe the following precautions. Failure to do so will not only put load on the
tires, but also reduce steering and braking performance. This could lead to an acci-
dent resulting in serious injury or even death.
●Do not overload the vehicle.
●Do not apply load to the vehicle unevenly.
