■Limitations of the pre-collision system
●The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Never use the pre-collision safety system instead of normal braking operations. This
system is not designed to avoid or reduce collisions in every situation. Overly relying
on the system or entrusting it with safety may lead to an accident resulting in death or
serious injury.
Although this system is designed to suppor t in avoiding a collision or reducing the
damage of a collision, its effectiveness may change according to various conditions
(  P. 292, 293). Therefore, the system may not always provide the same perfor-
mance. Also, pre-collision braking function may not operate depending on the oper-
ations of the driver. If the driver is stepping on the brake pedal or is operating the
steering wheel, the system may determine th at the driver is taking evasive action and
pre-collision braking func tion may not operate.
●As the pre-collision system is designed to assi st 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-collision 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 surr ounding area to a strong impact.
If the sensor moves even slightly off posi tion, 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.

This mode emphasizes enhanced
steering response.
TRACK mode
This mode emphasizes stability for
high speed sporty driving.
The multi-information display shows the distribution of driving force between the
right and left rear wheels. ( P. 1 1 0 )
TVD (Torque Vectoring Differential)

: If equipped
The TVD system distributes driving force (torque) between the right and 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.

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 melt the ice. Wipe away the water imme-
diately to prevent it from freezing.
●To ensure proper operation of the climate 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, chassis, 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 safe distance between you and the vehicle
ahead, and drive at a reduced speed 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 necessary,
block the wheels to prevent in advertent sliding or creeping.
Vehicles with front and rear tires of the same size
Use the correct tire chain size when mounting the tire chains.
Chain size is regulated for each tire size.
Side chain
(0.12 in. [3 mm] in diameter)
Cross chain
(0.16 in. [4 mm] in diameter)
Vehicles with front and rear tires of differing sizes
Tire chains cannot be mounted.
Snow tires should be used instead.
