■

Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will operate:

●

The shift lever 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:

●

The shift lever is shifted to P or N

●

The accelerator pedal is depressed

●

The parking brake is engaged

●

Approximately 2 seconds elapse after the brake pedal is released

■

When the battery is disconnected
The steering wheel may move from its straight forward position, but this will be corrected

automatically when driving. 

■

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 brake pedal is

depressed repeatedly, 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 sys-

tems.

●

Any of the following conditions 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 also 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.

■

EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be heard.

This does not indicate a malfunction.

■

Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automatically re-

enabled in the following situations:

●

When the engine switch is turned off

●

If only the TRAC system is turned off, the TRAC will turn on when vehicle speed

increases

If both the TRAC and VSC systems are turned off, automatic re-enabling will not occur

when vehicle speed increases.

■

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 engine off. The EPS system should return to normal

within 10 minutes.

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/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road

surfaces, even if the TRAC/VSC 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.

■

When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may cause an

accident. Exercise particular care when the indicator light flashes.

■

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.

■

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.

●

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.

Except vehicles with 18-inch tires
