4-5. Using the driving support systems

●

The accelerator pedal is depressed a 

large amount

WARNING

■

The ABS does not operate effectively 

when

●

The limits of tire gripping performance 

have been exceeded (such as exces-

sively 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 main-

tain 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 effec-

tively 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.

■

Active Cornering Assist does not 

operate effectively when

●

Do not overly rely on Active Corner-

ing Assist. Active Cornering Assist 

may not operate effectively when 

accelerating down slopes or driving on 

slippery road surfaces.

●

When Active Cornering Assist fre-

quently operates, Active Cornering 

Assist may temporarily stop operating 

to ensure proper operation of the 

brakes, TRAC and VSC.

■

Hill-start assist control does not oper-

ate 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 control to hold the vehi-

cle on an incline, as doing so may lead 

to an accident.

■

When the TRAC/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 speci-

fied size, brand, tread pattern and total 

load capacity. In addition, make sure that 

the tires are inflated to the recom-

mended tire inflation 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.

WARNING

■

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.

■

Secondary Collision Brake

Do not rely solely upon the Secondary 

Collision Brake. This system is designed 

to help reduce the possibility of further 

damage due to a secondary collision, 

however, that effect changes according 

to various conditions. Overly relying on 

the system may result in death or serious 

injury.

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 park-
ing 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 lead-
ing to an accident.

When the parking brake is in automatic 
mode, release the parking brake after shift-
ing the shift lever to P. (



P.140)

■

Ventilation and air conditioning odors

●

To let fresh air in, set the air conditioning 

system to the outside air mode.

●

During use, various odors from inside and 

outside the vehicle may enter into and 

accumulate in the air conditioning sys-

tem. This may then cause odor to be 

emitted from the vents.

●

To reduce potential odors from occur-

ring:

• It is recommended that the air condition-

ing system be set to outside air mode 

prior to turning the vehicle off.

• The start timing of the blower may be 

delayed for a short period of time imme-

diately after the air conditioning system is 

started in automatic mode or with the
