■Cruise control can be set when
●The shift lever is in the “D” or “4”, “5”, “6”, “7” or “8” (GS460) or “4”, “5”, or “6”
(GS350) range of “S”.
●Vehicle speed is between approximately 25 mph (40 km/h) and 125 mph
(200 km/h).
■Accelerating
The vehicle can be accelerated normally. After acceleration, the set speed
resumes.
■Automatic cruise control cancelation
The set speed is automatically canceled in any of the following situations.
●Actual vehicle speed falls more than 10 mph (16 km/h) below the preset vehicle
speed
At this time, the memorized set speed is not retained.
●Actual vehicle speed is below 25 mph (40 km/h)
●Enhanced VSC is activated
■If the cruise control indicator light flashes
Press the “ON-OFF” button off once, and then reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels immediately
after being activated, there may be a malfun ction in the cruise control system. Have
the vehicle inspected by your Lexus dealer.

■Vehicle-to-vehicle distance settings
Select a distance from the table below. Note that the distances shown correspond
to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle distance increases/
decreases in accordance with vehicle speed.
■Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle
distance control operates properly. (Some obstructions, such as snow, ice or plastic
objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
■Approach warning
In the following instances, there is a po ssibility that the warnings will not occur:
●When the speed of the vehicle ahead ma tches or exceeds your vehicle’s speed
●When the vehicle ahead is traveling at an extremely slow speed
●Immediately after the cruise control speed has been set
●At the instant the accelerator is applied

Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropria te to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific gravity of
battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
■ Before driving the vehicle
Perform the following according to the driving conditions.
● Do not try to forcibly open a window or move a wiper that is fro-
zen. Pour 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 accumu lated on the air inlet vents in
front of the windshield.
● Remove any ice that has accumul ated on the vehicle chassis.
● Periodically check for and remove any excess ice or snow that
may have accumulated in the wheel well or on the brakes.

Turn the knob to open or close
the vent
■Using the automatic mode
Fan speed is adjusted automatically in acc ordance with the temperature setting and
ambient conditions. As a result, the following may occur.
●The system may switch automatically to recirculated mode when the coolest
temperature setting is selected in summer.
●Immediately after the switch is pressed, the fan may stop for a while until warm
or cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.
■Using the system in recirculated air mode
The windows will fog up more easily if the recirculated air mode is used for an
extended period.
■Switching between outside air and recirculated air modes
Recirculated air mode or outside air mo de may be automatically switched to on
accordance with the temperature se tting and the inside temperature.
■Window defogger feature
Recirculated air mode may automatically switch to
(outside air) mode in situ-
ations where the windows need to be defogged.
■Outside temperature approaches 32 °F (0 °C)
The air conditioning system may no t operate even when is touched.

■MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1 /10 of their original size by using MP3
compression.
WMA (Windows Media
TMAudio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3 format.
There is a limit to the MP3 and WMA file standards and to the media/formats
recorded by them that can be used.
●MP3 file compatibility
• Compatible standards MP3 (MPEG1 LAYER3, MPEG2 LSF LAYER3)
• Compatible sampling frequencies MPEG1 LAYER3: 32, 44.1, 48 (kHz)
MPEG2 LSF LAYER3: 16, 22.05, 24 (kHz)
• Compatible bit rates MPEG1 LAYER3: 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 (kbps)

Wait a few seconds until the compass direction is displayed.
The calibration is complete.
■Circling calibration
If “CAL” appears on the display,
drive the vehicle at 5 mph (8 km/
h) or less in a circle until a direction
is displayed.
If there is not enough space to
drive in a circle, drive around the
block until the direction is dis-
played.

■Conditions unfavorable to correct operation
The compass may not show the correct direction in the following conditions:
●The vehicle is stopped immediately after turning.
●The vehicle is on an inclined surface.
●The vehicle is in a place where the earth’s magnetic field is subject to interfer-
ence by artificial magnetic fields (underground car park/parking lot, under a
steel tower, between buildings, roof car pa rk/parking lot, near an intersection,
near a large vehicle, etc.).
●The vehicle has become magnetized.
(There is a magnet or metal object near the inside rear view mirror.)

■Aluminum wheels
Remove any dirt immediately by using a neutral detergent. Do not use hard brushes
or abrasive cleaners. Do not use strong or harsh chemical cleaners. Use the same
mild detergent and wax as used on the paint.
■Bumpers and side moldings
Do not scrub with abrasive cleaners.
■To prevent paint deterioration and corrosion on the body
●Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If you see coal tar or tree sap on the paint surface
• If you see dead insects, insect droppings or bird droppings on the paint
• After driving in an area contaminated with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled in dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
●If the paint is chipped or scratched, have it repaired immediately.
CAUTION
■Caution about the exhaust pipe
Exhaust gasses cause the exhaus t pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled suffi-
ciently, as touching a hot exhaust pipe can cause burns.
