Defogging and defrosting
—The inside of the windshield
For best results, set controls to:
For automatic operation—
Temperature— Towards high temperature to heat; low temperature to cool
Air intake—OUTSIDE AIR
Air flow—WINDSHIELD
For manual operation—
Fan speed—To the desired fan speed
Temperature— Towards high temperature to heat; low temperature to cool
Air intake—OUTSIDE AIR
Air flow—WINDSHIELD
When the windshield air flow button is pushed, air flows mainly
from the windshield vents and turns on the defogging function
with the purpose of clearing the front view.
Pushing this button once again returns the air flow mode to the
last one used.
This button allows the air intake to select OUTSIDE AIR mode
automatically. This is to clean up the front view more quickly.
If you want to return the setting to RECIRCULATED AIR mode,
push the air intake control button once again. Touch the “A/C” switch for dehumidified heating or cooling.
This setting clears the front view more quickly.

Only humid days, do not blow cold air on the
windshield—the dif ference between the outside and inside
temperatures could make the fogging worse.
—The outside of the windshield
For best results, set controls to:

7. Take out the filter.
G21022
8. Remove the filter from the filter case.
9. Inspect the filter on the surface.
If it is dirty, it should be replaced.
NOTICE
When setting the filter to the filter case, the UP marks
shown on the filter and filter case should be noted and
fitted as shown.
INFORMATION
The air conditioning filter should be installed properly
in position. The use of air conditioning with the filter
removed may cause deteriorated dustproof perfor-
mance and then affect air conditioning performance.

STARTING AND DRIVING
358“4” (fourth range): The most suitable gear is automatically
selected between
first and fourth gears according to vehicle
speed and driving conditions. In the “4” (fourth range)
position, the automatic transmission system will select the
most suitable gear to handle current running conditions
such as hill climbing, hard towing, etc.
“3” (third range): The most suitable gear is automatically
selected between first and third gears according to vehicle
speed and driving conditions. This range is best used when
stronger engine braking is necessary.
“2” (second range): First or second gear will automatically
be selected according to vehicle speed and driving
conditions. This range is to be used when engine braking
stronger than that of the “3” (third range) position is
necessary.
“1” (first range): This gear is fixed in first regardless of
vehicle speed or driving conditions. This range is to be used
when maximum engine braking is necessary.
If you attempt to downshift the transmission when it is not
possible to downshift due to high vehicle speed, a warning tone
sounds twice. 
Maximum allowable speeds
To get on a highway or to pass slower traffic, maximum
acceleration may be necessary. Make sure you observe the
following maximum allowable speeds in each range:
range km/h (mph)
GS430: 1 57 (35)
2 97 (60)
3 141 (88)
range km/h (mph)
GS300 (2WD): 1 54 (33)
2 93 (58)
3 137 (85)
range km/h (mph)
GS300 (4WD): 1 52 (32)
2 90 (56)
3 131 (81)
NOTICE
Do not downshift if you are going faster than the
maximum allowable speed for the next lower range.

NOTE:
* The detection range can be changed from about 50 cm
(1.5 ft.) for dual sensors and about 60 cm (2 ft.) for back
sensors.
Ask your Lexus dealer for details.
The intuitive parking assist may not work properly in the
following cases:
 When the bumper is damaged.
 When the part near the sensors is subjected to a strong
impact.
 When an accessory is installed within the sensor detection
range.
 When snowflakes or mud gets on the sensors.
(If removed, the system will work properly.)
 When water is splashed from a high pressure car wash or
steam on the sensors.
 When a sensor is covered with your hand.
 When the vehicle is tilted.
 In extreme hot or cold weather
(In extreme cold weather, the error display appears and the
system becomes inoperative.)
 When driving on bumpy roads, slopes, gravelled roads or
grass. 
Devices issuing ultrasonic waves are operated around your
vehicle, such as a horn from another vehicle, motorcycle
engine, air braking sound from heavy −duty vehicles.
 When another vehicle equipped with ultrasonic sensors
gets close to your vehicle.
 When heavy rain or water is splashed over the vehicle.
(Drive carefully as the braking distance may be affected.)
 When a radio antenna or fender pole is mounted on your
vehicle.
 If towing eyelet is installed on your vehicle.
 When you are driving towards a tall curb stone or curb stone
having right angle.
 The detection range for an object such as a traffic sign may
be shortened.
 An object just under the bumper cannot be detected.
Although an object lower than the location of sensors is
once detected, the detection might be stopped when your
vehicle gets closer to the object.
 When an obstacle is very close to the sensors.

STARTING AND DRIVING
406(d) Changing vehicletovehicle distance
G31016

Long 2Middle 3Short
You can select one of the following vehicletovehicle
distances: “Long”, “Middle” or “Short”. Each time you
pull the distance switch briefly toward you, the setting
changes from “Long” to “Middle” to “Short” and then
back to “Long”. You can confirm the setting on the
multiinformation display.
It should be noted that pulling the “DISP” switch will change to
another screen.
Your vehicle speed changes in proportion to the speed of
the vehicle ahead, maintaining the selected distance.
However, if the vehicle speed is slower, the selected
distance will be shorter than the designated distance.
When the vehicle− to−vehicle distance control mode is
activated or the multi−information display indicates “RADAR
READY”, the vehicle −to −vehicle distance setting can be
changed. The vehicle−
to−vehicle distance is always set to “Long” when
the engine switch is turned on.
CAUTION
 Select the vehicletovehicle distance
considering traffic conditions. The approximate
vehicletovehicle distance based on time
interval when driving at 80 km/h (50 mph) is
shown below :
“Long” about 50 m (about 164 ft.) . . . . . . . .
“Middle” about 40 m (about 132 ft.) . . . . . .
“Short” about 30 m (about 100 ft.) . . . . . . .
If the vehicle speed is slower than 80 km/h (50 mph),
the distance will be shorter than the above.
 During long downhill driving, the vehicletovehicle
distance will be shorter than the selected distance.

DRIVING TIPS
453
Keep ice
and snow from accumulating under the fenders.
Ice and snow built up under your fenders can make steering
difficult. During bad winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving, we recommend you
carry some emergency equipment.
Some of the things you might put in the vehicle are tire chains,
window scraper, bag of sand or salt, flares, small shovel,
jumper cables, etc.
DINGHY TOWING
G32001
Your vehicle is not designed to be dinghy towed (with four
wheels on the ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four wheels on the ground.
This may cause serious damage to your vehicle.

TRAILER TOWING
G32002
Lexus does not recommend towing a trailer with your
vehicle. It is not designed for trailer towing.
HOW TO SAVE FUEL AND MAKEYOUR VEHICLE LAST LONGER
Improving fuel economy is easy − just take it easy. It will help
make your vehicle last longer, too. Here are some specific tips
on how to save money on both fuel and repairs:
 Keep your tires inflated at the correct pressure. Check
the inflation pressure every two weeks, or at least once a
month. Underinflation causes tire wear and wastes fuel.
 Do not carry unneeded weight in your vehicle. Excess
weight puts a heavier load on the engine, causing greater
fuel consumption.
 Avoid lengthy warmup idling. Once the engine is
running smoothly, begin driving − but gently. Remember,
however, that on cold winter days this may take a little
longer.
 Always keep the automatic transmission selector lever
in the “D” position when engine braking is not required.
Driving with the overdrive off will reduce the fuel economy.
(For details, see “Automatic transmission” on page 353.)
 Accelerate slowly and smoothly. Avoid jackrabbit starts.
 Avoid long engine idling. If you have a long wait and you
are not in traffic, it is better to turn off the engine and start
again later.
 Avoid engine overrevving. Use a gear position suitable
for the road on which you are traveling.
