4-5. Using the driving support systems

Driving

■

TRAC (Traction Control)

Helps to maintain drive power and pre-
vent the drive wheels from spinning
when starting the vehicle or accelerat-
ing on slippery roads

■

Hill-start assist control

Helps to reduce the backward move-
ment of the vehicle when starting on an
uphill

■

VGRS (Variable Gear Ratio Steer-
ing) (if equipped)

Adjusts the front wheel turning angle in
accordance with the vehicle speed and
steering wheel movement

■

DRS (Dynamic Rear Steering) (if
equipped)

Contributes to the turning characteris-
tics and responsiveness of the vehicle
by adjusting the rear wheel angle of the
vehicle in accordance with steering
wheel movement.

■

EPS (Electric Power Steering)

Employs an electric motor to reduce
the amount of effort needed to turn the
steering wheel

■

Adaptive Variable Suspension Sys-
tem (if equipped)

By independently controlling the
damping force of the shock absorbers
for each of the 4 wheels according to
the road and driving conditions, this
system combines riding comfort with
superior vehicle stability, and helps
good vehicle posture.

■

LDH (Lexus Dynamic Handling
system) (if equipped)

Provides integrated control of the
VGRS, DRS and EPS. Contributes to
turning characteristics at low speeds,
responsiveness at medium speeds and
safety at high speeds by controlling the
steering angle of the front and rear
wheels in accordance with the steering
wheel operation and vehicle speed.

■

VDIM (Vehicle Dynamics Inte-
grated Management)

Provides integrated control of the
ABS, brake assist, TRAC, VSC,
hill-start assist control, EPS and VGRS
systems
Helps to maintain vehicle stability when
swerving on slippery road surfaces by
controlling the brakes, engine output,
steering assist, and steering ratio

■

TRAC is temporary deactivated. If the infor-

mation continues to show, contact your

Lexus dealer.

■

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/back-

ward on an upward incline).

●

The vehicle is stopped.

●

The accelerator pedal is not depressed.

●

The parking brake is not engaged.

●

The shift lever is moved to P or N.

●

The accelerator pedal is depressed.

●

The parking brake is engaged.

●

2 seconds at maximum elapsed after the

brake pedal is released

●

Engine switch is turned to off

■

VGRS is disabled when

VGRS may stop operating in the following

situations.

In this event, the steering wheel may move

from its straight forward position, but it will

return when the system restarts.

●

When the steering wheel is operated for

an extended period of time while the

vehicle is stopped or is moving very

slowly

(on vehicles with LDH, DRS is disabled

The center position of the steering wheel

may change when VGRS is disabled. How-

201

4-5. Using the driving support systems

Driving

ever, the position will return to normal after

VGRS is reactivated.

■

When the battery is disconnected (vehi-

cles with VGRS)

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, hill-start

assist control and VGRS 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

systems.

●

Any of the following conditions may

occur when the above systems are oper-

ating. None of these indicates that a mal-

function 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, VGRS and DRS 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/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 sys-

tem

The effectiveness of the EPS system is

reduced to prevent the system from over-

heating 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.

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

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.

202

4-5. Using the driving support systems

WARNING

■

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.

■

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.

Alert with steering control) system.

NOTICE

■

Repairing or replacing snow tires

Request repairs or replacement of snow

tires from Lexus dealers or legitimate tire

retailers.

This is because the removal and attach-

ment of snow tires affects the operation

of the tire pressure warning valves and

transmitters.

Before driving the vehicle

204

warm water over the frozen area to
melt the ice. Wipe away the water
immediately 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 accumu-
lated 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 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.135)



If the vehicle is parked without set-
ting 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 position 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 vehi-
cle inspected by your Lexus dealer
immediately.
