■Conditions that may trigger the system even if there is no danger of a collision
In any of the following situations where the frontal area of the radar sensor is inter-
rupted, the radar sensor may detect possibility of a frontal collision and the system
may be activated.
●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 object (billboar d, low ceiling, fluorescent light, etc.) above
the uphill road ahead
●When driving on a narrow road or throug h 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 trunk etc.)
When the system is activated in the situations described above, there is also a possibility
that the brakes may be applied wi th a force greater than normal.
■Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also be occa-
sions when the sensor cannot de tect 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 yo ur vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
●In inclement weather such as heavy rain, fog, snow or sand storms
●If the vehicle is skidding when VSC is not operating
●When your vehicle is steeply inclined
●When only part of your vehicle’s front end collides with, or contacts, a vehicle or object
in a frontal collision
●When the radar sensor moves off position du e to its surrounding area being subjected
to a strong impact
●When an obstacle suddenly appears in front of the vehicle due to the steering wheel
being turned sharply or another cause
■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor cont amination, etc. that results in the sensors
being unable to detect obstac les, the pre-collision system will be automatically disabled.
In this case, the system will not activate even if there is a collision possibility.

WARNING
■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-collision 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 syst em. Failure to do so may cause an accident,
resulting in death or serious injury.
●This system has been designed to help av oid and reduce the impact of collisions.
However, the system operates differently depending on the situation ( →P. 308,
309). As a result, the same level of performance may not be expected in all cases.
Also, the pre-collision brakes may not operate if the driver is depressing the brake
pedal or turning the steering wheel, as the system will determine such conditions as
collision avoidance operations.
●As the pre-collision system is designed to assist the driver in safe driving, it may oper-
ate under sporty driving conditions, whic h may cause an accident. For this reason
under sporty driving conditions, it is reco mmended that this system be disabled by
using the PCS OFF switch.
■Handling the radar sensor
Observe the following to ensure the pre-co llision system can function effectively.
Otherwise, the system may not function correctly and could result in an accident.
●Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or damage
them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even s lightly off position, the system may become inaccurate or
malfunction. If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by your Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding area.
●Do not modify or paint the sensor and grille cover.
●If the radar sensor needs to be replaced, contact your Lexus dealer.

With the engine switch in IGNITION
ON mode, pressing the TVD switch
changes the TVD control mode.
The current TVD control mode will be
displayed on the meters.
STANDARD mode
This is the default mode and pro-
vides an optimum balance of driving
agility and stability.
SLALOM mode
This mode emphasizes enhanced
steering response.
TRACK mode
This mode emphasizes stability for
high speed sporty driving.
The multi-information display shows the di stribution of driving force between the
right and left rear wheels. ( →P. 117)
TVD (Torque Vectoring Differential)∗
∗
: If equipped
The TVD system distributes driving force (torque) between the right an\
d left
rear wheels automatically. This syst em contributes to enhanced steering
response while cornering and increased traction when exiting a corner, pro-
viding an agile driving experience.

3324-6. Driving tips
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen. Pour
warm water over the frozen area to me lt the ice. Wipe away the water imme-
diately to prevent it from freezing.
●To ensure proper operation of the c limate control system fan, remove any
snow that has accumulated on the air inlet vents in front of the windshield.
●Check for and remove any excess ice or snow that may have accumulated on
the exterior lights, vehicle’s roof, chassi s, around the tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before getting in the
vehicle.
Accelerate the vehicle slowly, keep a sa fe distance between you and the vehicle
ahead, and drive at a reduced spee d suitable to road conditions.
●Park the vehicle and move the shift lever to P without setting the parking
brake. The parking brake may freeze up, preventing it from being released. If
the vehicle is parked without setting the parking brake, make sure to block the
wheels.
Failure to do so may be dangerous because it may cause the vehicle to move
unexpectedly, possibly leading to an accident.
●If the vehicle is parked without setting the parking brake, confirm that the shift
lever cannot be moved out of P
*.
*: The shift lever will be locked if it is atte mpted to be shifted from P to any other posi-
tion without depressing the brake pedal. If the shift lever can be shifted from P, there
may be a problem with the shift lock sy stem. Have the vehicle inspected by your
Lexus dealer immediately.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehi cle 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 ti re chains being used, or 30
mph (50 km/h), whichever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden acceleration, abrupt 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.
●Vehicles with LDA (Lane Departure Alert): Do not use the LDA system.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow ti res from Lexus dealers or legitimate tire
retailers.
This is because the removal an d attachment of snow tires affects the operation of the
tire pressure warning va lves and transmitters.
■Fitting tire chains
The tire pressure warning valv es and transmitters may not function correctly when tire
chains are fitted.
