Driving
The slip indicator light will flash while
the VSC/TRAC/ABS systems are
operating.
If the vehicle gets stuck in mud, dirt or snow, the TRAC system may reduce
power from the hybrid system to the wheels. Pressing to turn the system
off may make it easier for you to rock the vehicle in order to free it.
To turn the TRAC system off, quickly
press and release .
The “TRAC OFF” indicator light will
come on.
Press again to turn the system
back on.
■When the “TRAC OFF” indicator comes on even if the TRAC OFF switch has not been
pressed
TRAC and hill-start assist control cannot be operated. Contact your Lexus dealer.
■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 hybrid system is
started, just after the vehicle begins to move, if the brake pedal is depressed forcefully
or repeatedly, or 1-2 minutes after the hybrid system is stopped. This sound does not
indicate that a malfunction has occurred in any of these systems.
●Any of the following condit ions 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 slig htly after the ABS is activated.
• The brake pedal may move down s lightly after the ABS is activated.

■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be heard.
This does not indicate a malfunction.
■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 hybrid system off. The EPS system should return to nor-
mal 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 position 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:
●Shift the shift position to P or N
●The accelerator pedal is depressed
●The parking brake is engaged.
●Approximately 2 seconds elapse after the brake pedal is released.
■Automatic reactivation of TRAC system
After turning the TRAC system off, the system will be automatically re-enabled in the fol-
lowing situations:
●When the power switch is turned off
●The TRAC will turn on when vehicle speed increases

■Conditions that may trigger the system even
if there is no possibility of a collision
In any of the following situations where the fr ontal area of the radar sensor is interrupted,
the radar sensor may detect possibility of a fr ontal collision and the system may be acti-
vated.
●When passing by an oncoming vehicle in a curve or a turn to the right or the left
●When rapidly approaching an obstacle ahead (e.g. preceding vehicle, toll gate barrier,
etc.)
●When there is a structural ob ject (billboard, low ceiling, fluorescent light, etc.) above
the uphill road ahead
●When driving on a narrow road or through under a low overhead structure (bridge,
tunnel, fly-under, etc.)
●When driving on an uneven road surface
●When there is a metal object, bump, or protrusion on the road surface
●When vehicle’s front part is raised or lowered depending on loading conditions
●When the direction of radar sensor is misa ligned by strong impact applied on an area
around the radar sensor, etc.
●When there is an obstacle (guard rail, etc.) by the roadside at the entrance to a curve
●When the front of your vehicle is pointing upwards (caused by putting a heavy load in
the luggage compartment etc.)
When the system is activated in the situations described above, there is also a possibility
that the seat belts will retract quickly and the brakes may be applied with a force greater
than normal. When the seat belt is locked in the retracted position, stop the vehicle in a
safe place, release the seat belt and refasten it.
■Obstacles not detected
The sensor cannot detect plasti c obstacles such as traffic cones. There may also be occa-
sions when the sensor cannot detect pedestrians, animals, bicycles, motorcycles, trees,
or snowdrifts.
■Situations in which the pre-collision system does not function properly
The system may not function effectively in situations such as the following:
●On roads with sharp bends or uneven surfaces
●If a vehicle suddenly moves in front of vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of vehicle, such as when overtaking
●In inclement weather such as heav y rain, fog, snow or sand storms
●When your vehicle is skidding with the VSC system off
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
●Due to greatly turning the steering wheel when an obstacle suddenly appears ahead

■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the sensors
being unable to detect obstacles, the pre-collision syst em will be automatically disabled.
In this case, the system will not activate even if there is a collision possibility.
■When there is a malfunction in the system, or if the system is temporarily unusable
Warning lights and/or warning mess ages will turn on or flash. (P. 535, 542)

■Limitations of the pre-collision system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Do not use the pre-collisions system instea d of normal braking operations under any
circumstances. This system will not prevent collisions or lessen damage or injuries in all
cases. Do not overly rely on this system. Failu re to do so may cause an accident, result-
ing in death or serious injury.
This system has been designed to help av oid and reduce the impact of collisions. How-
ever, the system operates differently depending on the situation ( P. 243, 244). As a
result, the same level of performance may not be expected in all cases. Also, the pre-
collision’s brakes may not operate if the driver is depressing the brake pedal or turning
the steering wheel, as the system will dete rmine such conditions as collision avoidance
operations.

■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or serious injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive in excess of 75 mph (120 km/h), regardless of the type of snow tires
being used.
●Use snow tires on all, not just some wheels.
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being used, or 30
mph (50 km/h), whichever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden acceleration, ab rupt steering, sudden braking and shifting operations
that cause sudden engine braking.
●Slow down sufficiently before entering a cu rve to ensure that vehicle control is main-
tained.
■When parking the vehicle
When parking the vehicle without applying the parking brake, make sure to chock the
wheels. If you do not chock the wheels, the vehicle may move unexpectedly, possibly
resulting in an accident.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attachment of snow tires affects the operation of the
tire pressure warning valves and transmitters.
■Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly when tire
chains are fitted.
