■Circling calibration
Stop the vehicle in a place where it is safe to drive in a circle.
Press and hold the switch for 9
seconds.
“C” appears on the compass display.
Drive the vehicle at 5 mph
(8 km/ h) or less in a circle until a
direction is displayed.

in a circle, drive around the block
until the direction is displayed.
■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 ma gnetic field is subject to interference by
artificial magnetic fields (underground car park/parking lot, under a steel tower,
between buildings, roof car park/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.)
●The battery has been disconnected.

Maintenance and care
■Repair and replacement
It is recommended that genuine Lexus parts be used for repairs to ensure performance
of each system. If non-Lexus parts are used in replacement or if a repair shop other than
a Lexus dealer performs repairs, confirm the warranty coverage.
■Resetting the message indicating maintenance is required (U.S.A. only)
After the required maintenance is performed according to the maintenance schedule,
please reset the message.
To reset the message, follow the procedure described below:Press or of the meter control switch, select .
Press or of the meter control switch , select “Scheduled Maintenance” and
then press .
Select the “Yes” and press .
■Allow inspection and repairs to be performed by a Lexus dealer
●Lexus technicians are well-trained specialists an d are kept up to date with the latest ser-
vice information. They are well informed ab out the operations of all systems on your
vehicle.
●Keep a copy of the repair order. It proves that the maintenance that has been per-
formed is under warranty coverage. If any problem should arise while your vehicle is
under warranty, your Lexus dealer will promptly take care of it.
A message will be displayed when the reset
procedure has been completed.

Maintenance and care
■Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the following situations,
oil consumption may increase, and engine o il may need to be refilled in between oil
maintenance intervals.
●When the engine is new, for example directly after purchasing the vehicle or after
replacing the engine
●If low quality oil or oil of an inappropriate viscosity is used
●When driving at high engine speeds or with a heavy load, or when driving while accel-
erating or decelerating frequently
●When leaving the engi ne idling for a long time, or when driving frequently through
heavy traffic
■After changing the engine oil
The engine oil maintenance da ta should be reset. Perform the following procedures:
Press or of the meter control switch, select .
Press or of the meter control switch, select “Oil Maintenance” and then press
.
Select the “Yes” and press .
A message will be displayed when the reset
procedure has been completed.

■Used engine oil
●Used engine oil contains potentially harm ful contaminants which may cause skin dis-
orders such as inflammation and skin canc er, so care should be taken to avoid pro-
longed and repeated contact. To remove used engine oil from your skin, wash
thoroughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner. Do not dispose of
used oil and filters in household tras h, in sewers or onto the ground.
Call your Lexus dealer, service station or auto parts store for information concerning
recycling or disposal.
●Do not leave used engine oil within the reach of children.

Maintenance and care
If any washer does not work or the
warning message appears on the multi-
information display, the washer tank
may be empty. Add washer fluid.
Washer fluid
WA R N I N G
■When adding washer fluid
Do not add washer fluid when the engine is hot or running as washer fluid contains
alcohol and may catch fire if spilled on the engine etc.
NOTICE
■Do not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces.
■Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the label of the washer fluid bottle.

Maintenance and care
Your vehicle is equipped with a tire pressure warning system that uses tire pres-
sure warning valves and transmitters to detect low tire inflation pressure before
serious problems arise.
●If the tire pressure drops below a predetermined level, the driver is warned by
a screen display and a warning light. ( P. 4 7 8 )
●The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. (P. 7 8 )
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-
information display.
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and transmitters
must also be installed.
When new tire pressure warning valves and transmitters are installed, new ID
codes must be registered in the tire pressure warning computer and the tire
pressure warning system must be initialized. Have tire pressure warning valve
and transmitter ID codes registered by your Lexus dealer. ( P. 4 3 8 )
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the following circum-
stances:
●When rotating the tires.
●When the tire inflation pressure is changed such as when changing travel-
ing speed or load weight.
When the tire pressure warning system is initialized, the current tire inflation
pressure is set as the benchmark pressure.

■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to highway driving under
dry conditions. Since summer tires do not have the same traction performance as
snow tires, summer tires are inadequate for
driving on snow-covered or icy roads. For
driving on snow-covered roads or icy roads, the use of snow tires is recommended.
When installing snow tires, be sure to replace all four tires.
●All season tires
All season tires are designed to provide better traction in snow and to be adequate for
driving in most winter condit ions as well as for use year-round. All season tires, how-
ever, do not have adequate traction performance compared with snow tires in heavy
or loose snow. Also, all season tires fall short in acceleration and handling perfor-
mance compared with summer tires in highway driving.
●Snow tires
For driving on snow-covered roads or icy roads, we recommend using snow tires. If
you need snow tires, select tires of the same size, construction and load capacity as the
originally installed tires. Since your vehicle has radial tires as original equipment, make
sure your snow tires also have radial cons truction. Do not install studded tires without
first checking local regulations for possible re strictions. Snow tires should be installed
on all wheels. ( P. 2 6 0 )
■If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.
■Situations in which the tire pressure warning system may not operate properly
●In the following cases, the tire pressure warning system may not operate properly.
• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the wheels or wheel
housings.
• If the tire inflation pressure is extremely higher than the specified level.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large display, air-
port or other facility th at generates strong radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or other wireless
communication device
If tire position information is not correctl y displayed due to the radio wave conditions,
the display may be corrected by driving and changing the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to start or go off could be
extended.
●When tire inflation pressure declines rapidly for example when a tire has burst, the
warning may not function.
