worn tires on a snow covered road).

●

The vehicle hydroplanes while driving at high speed on wet or slick roads.

■

Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain a

safe distance from the vehicle in front of you, especially in the following situations:

●

When driving on dirt, gravel or snow-covered roads

●

When driving with tire chains

●

When driving over bumps in the road

●

When driving over roads with potholes or uneven surfaces

■

TRAC may not operate effectively when

surfaces, even if the TRAC system is operating.

Drive the vehicle carefully in conditions where stability and power may be lost.

■

Hill- start assist control does not operate effectively when

●

Do not overly rely on hill-start assist control. Hill-start assist control may not operate

effectively on steep inclines and roads covered with ice.

●

Unlike the parking brake, hill-start assist control is not intended to hold the vehicle

stationary for an extended period of time. Do not attempt to use hill-start assist con-

trol to hold the vehicle on an incline, as doing so may lead to an accident.

■

WARNING

■

When the TRAC/VSC 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 vehicle stability and driving force, do not turn the

TRAC/VSC systems off unless necessary.

■

Expert mode precautions

●

Do not use on public roads.

●

Use only when the road conditions and safety of the surrounding area can be

ensured.

●

Proper use of expert mode requires a professional level of driving skill. When using

expert mode, always check the road conditions and surrounding area and drive more

carefully than usual.

■

Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load

capacity. In addition, make sure that the tires are inflated to the recommended tire infla-

tion pressure level.
The ABS, TRAC and VSC systems will not function correctly if different tires are

installed on the vehicle.

Contact your Lexus dealer for further information when replacing tires or wheels.

■

Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the driving

assist systems, and may cause a system to malfunction.

RC F_U

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
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 attempted 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 system. Have the vehicle inspected by your
Lexus dealer immediately.
