STARTING AND DRIVING
365 In the power mode, the “ECT PWR” light in the instrument
cluster is on and the most suitable shift pattern is selected
depending on the driver’s operation of accelerator and brake
pedal and on the vehicle condition. See “Automatic shifting
point change control” on page 356.
To return to the normal mode, push the driving pattern selector
switch lightly on the “SNOW” side.
Snow mode: For slippery road surfaces such as in snow. In
this mode, the spinning of the rear wheels is controlled
appropriately.
When you push the driving pattern selector switch on the
“SNOW” side, the snow mode is turned on and the ”ECT
SNOW” light in the instrument cluster comes on.
To return to the normal mode, push the driving pattern selector
switch on the “SNOW” side again.
When you turn the engine switch off in the snow mode, the
electronic throttle control system automatically changes to the
normal mode.
INTUITIVE PARKING ASSIST
G31049
The intuitive parking assist is a warning system used
when parking the vehicle at low speed (e.g. into a garage).
It uses an ultrasonic sensor, which checks the
approximate distance to an obstacle. It will inform you of
the approximate distance to an obstacle by displaying
information on the multi−information display and the
screen, and with beeping sounds.

Resuming the preset speed
If the preset speed has been cancelled, when you push the
lever up in the “+ RES” direction while “RADAR READY”
shows up on the multi−information display and at a vehicle
speed of about more than 40 km/h (25 mph), the speed set
prior to cancellation will be restored.
During follow−up cruising, if there are no vehicles running
ahead because they have changed lanes, your vehicle will
accelerate gradually up to the preset speed.CAUTION
Deceleration cruising function and approach
warning do not operate when the vehicle ahead is at
a stop or driving very slowly.
While vehicle−to−vehicle distance control is on (on
follow−up cruising), acceleration and deceleration
are automatically performed in proportion to the
speed of the vehicle ahead detected. However, if the
vehicle ahead of you decelerates abruptly or if
another vehicle cuts in ahead of you, your vehicle
may collide with the vehicle ahead unless you
manually depress the brake pedal to slow down your
vehicle. If you need to accelerate because the vehicle
ahead or you changes lanes, then depress the
acceleration pedal.
Depending on the road configuration (curved roads,
left and right continuous curved roads, driving at the
start or end of the curve, narrow driving lanes due to
road construction) or your vehicle condition
(steering wheel maneuvering, position in the lane or
unstable driving because of an accident or
breakdown), vehicles in other lanes or surrounding
objects will be detected, resulting in a control failure
or the activated approach warning. This may also
result in a very close distance between vehicles due
to a failure to detect the vehicle ahead. Maneuvering
the steering wheel in response to a violent lateral
wind will cause similar conditions.

GS430 2
GS300
If the hill−start assist control system malfunctions, the
slip indicator light (two−wheel drive models only) and
brake system warning light (yellow) come on. At this time,
the above message appears. (GS430 only—In some
cases, the multi−information display shows either
“CHECK VSC” or “CHECK ECB” only.)
If the message appears, the hill−start assist control system,
vehicle stability control system and traction control system do
not work. Although it is no problem to continue driving, have
your vehicle checked by your Lexus dealer as soon as
possible.
VARIABLE GEAR RATIO
STEERING SYSTEM
(GS430 only)
The variable gear ratio steering system adjusts the wheel
turning angle depending on the vehicle speed and how
much you turn the steering wheel.
The vehicle wheel turning angle will be changed with a smaller
degree of wheel maneuvering when you are driving at very low
speed such as when putting your vehicle into a garage.
When you start or stop the engine, you may hear a small noise
and the steering wheel may move slightly. This is caused when
the system starts or stops, and does not indicate a malfunction.
In the following cases, to prevent the system from overheating,
the system could be temporarily deactivated with the change
in the center position of the steering wheel. This is not a
malfunction. After the cause of the problem is eliminated, the
system will return to normal automatically after a few minutes.
If you continue maneuvering the steering wheel when the
vehicle is stopped or running at very low speed
If you continue driving holding the steering wheel to the
extreme right or left
If you maneuver the steering wheel immediately after
starting the engine at less than about −30C (−22F)

STARTING AND DRIVING
425 While the system is not functioning, a larger degree of wheel
maneuvering is needed during driving at low speed. If the
center position of the steering wheel is changed frequently,
have your vehicle inspected at your Lexus dealer.
CAUTION
Take due care especially when driving at low speed as
the vehicle changes direction in greater proportion to
the steering wheel maneuvering.
NOTICE
Do not disconnect the battery with the steering wheel
turned, or the center position of the steering wheel
could be slightly and temporarily changed. However,
after driving for a short while, the system will return to
normal and the center position of the steering wheel will
be in the appropriate position.
If you disconnect and reconnect the battery terminal, the
system is reset temporarily. However, it is no problem to drive.
Drive for a short while, the system will be set automatically and
return to normal.
Variable gear ratio steering system failure
warning
G31044
If there is any malfunction in the system, the above message
appears and the master warning light comes on.
If the warning message and light come on while driving, the
system is not working. Although conventional steering
operates when maneuvered, a larger degree of wheel
maneuvering (than at the time when the system is functioning
properly) is needed when driving at low speed. At this time, the
center position of the steering wheel could be changed.
Although it is no problem to continue driving, have your vehicle
repaired at your Lexus dealer.

436Vehicles with standard tires:
Stop your vehicle at a safe place as soon as possible and
check that the tire inflation pressure is as specified on the tire
and loading information label. If the low tire pressure warning
light comes on even after tire inflation pressure adjustment, it
is probable that you have a flat tire. If the tire goes flat, change
to the spare tire. (See page 469.)
The spare tire is not equipped with the tire pressure sensor.
So, the low tire pressure warning light remains on even if the
spare tire is mounted.
The light goes off a few minutes after air is put into the deflated
tire.
CAUTION
If the low tire pressure warning light comes on, observe
the following instructions:
Decelerate as soon as possible to the most
appropriate speed that conditions permit.
Avoid abrupt steering wheel maneuvering and
braking. If the vehicle tires deteriorate, you could
lose control of the steering wheel or the brakes,
causing death or serious injury.
The warning system may not activate immediately if
bursts or sudden air leakage should occur.
When the tyre pressure warning system warning light is
lit, one or more of your tyres is significantly
under−inflated. You should stop and check your tyres
as soon as possible, and inflate them to the proper
pressure as indicated on the vehicle’s tyre information
placard. Driving on a significantly under−inflated tire
causes the tyre to overheat and can lead to tyre failure.
Under−inflation also reduces fuel efficiency and tyre
tread life, and may affect the vehicle’s handling and
stopping ability. Each tyre, including the spare, should
be checked monthly when cold and set to the
recommended inflation pressure as specified in the
vehicle placard and owner’s manual.

Replacing tires and wheels
As you might have difficulty in locating a flat or deflated
tire, a tire pressure warning system should be installed on
the tires of this vehicle.
When replacing the wheels, be sure to install tire pressure
sensors on the wheels.
There are 3 ways to set up the tire pressure sensors:
a. Remove the sensor from the old wheel and install it to the
new wheel.
b. Keep the same wheel with tire pressure sensor and replace
the tire alone.
c. Use a new wheel and sensor.
You have to register an ID code for a new sensor. Up to 2
sets of codes can be registered. As one ID for the originally
installed sensor is registered at “MAIN” of the selector
switch, use the “2nd” position to register an ID for the new
sensor.
You do not need to re−register the ID code for any other
replacements. For the use of the originally installed tires,
put the selector switch at “MAIN” and for the use of tires set
purchased later, put the switch at “2nd”. For the sensor
selector switch, see page 442.

NOTICE
Do not turn the engine switch off during initialization,
or the system may not function properly due to
incomplete initialization.
Check which tires are being used before initialization
of the system, and also check the selector switch
position. (See the following “Selector switch”.)
Selector switch
G31005

Main position 2
2nd position
The selector switch is located on the underside of the
glove box.
The ID code is given in the tire pressure sensor. To
activate the tire pressure warning system, it is necessary
to register the ID code of the sensor on the selector switch
in the vehicle.
2 sets of ID codes can be registered. The code of the tires
originally installed on the vehicle is registered on the switch at
“MAIN”. Have a new tires set with new tire pressure sensors
registered at “2nd” by Lexus dealer.
ID codes should be registered by Lexus dealer. Once
registered, change the setting position each time you purchase
tires and wheels. Re−registration is not required.
When purchasing new tires, consult your Lexus dealer.
