ODOMETER AND TRIP METER
G13045
This meter displays the odometer and two trip meters. To
change the mode indication, use the “ODO TRIP” switch.
The “ODO TRIP” switch is located in the switch box.
G13004
Push the button to use the switch box and then push the
“ODO TRIP” switch. The odometer records the total distance the vehicle has
been driven. The twin trip meter records two different
distances independently.
For example, you can use one meter to calculate the fuel
economy and the other to measure the distance on each trip.
To change the trip meter indication from one trip to the
other, push the “ODO TRIP” change switch. To set the A
trip meter to
zero, display the A meter reading, then push
the “RESET” switch. The same applies for the B trip
meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.
After operation, be sure to close the switch box to its original
position.
CAUTION
To reduce the chance of injury in case of an accident or
a sudden stop, keep the switch box closed when not in
use while driving.

Low Engine Oil Level Warning
G13022
When the engine oil level is too low, the master warning
light comes on, a warning tone sounds, and the above
message appears.
Add oil as soon as possible. (For instructions, see “Checking
the engine oil level” on page 530.)
While driving on steep inclines or rough roads which causes
the vehicle to substantially sway or on curves, this message
may appear due to the movement of engine oil in the engine.
In normal conditions, due to engine oil consumption, this
message may a ppear earlier than the specified service interval
of the scheduled maintenance. This is because the engine oil
is consumed to the low level within the scheduled maintenance
interval and does not indicate a problem. (For detailed
information, see “Facts about engine oil consumption” on page
528.)
NOTICE
Continued engine operation with low engine oil will
damage the engine.
 Engine Oil Maintenance Reset Warning (U.S.A.

change the display to blank.
2. Turn the engine switch off.
3. Turn the engine switch on with the trip meter “RESET”
switch held down.

If the driving range exceeds 4,500 miles after the engine
oil maintenance data is reset, the master warning light
comes on, a warning tone sounds and the above message
appears for about 15 seconds when you select the engine
switch in “IGON” mode.
This message indicates that the engine oil should be replaced
soon. If the message appears, it is recommended to inspect
the engine oil with the engine switch off. For details about
inspection, see “Checking the engine oil level” on page 530.
If the engine oil level is low, engine oil should be replaced.
Have it replaced at your Lexus dealer.
After the engine oil replacement, reset the engine oil
maintenance data and make sure the “OIL MAINT RESET”
appears on the display.
NOTICE
The warning message on the display is based on the
driving range after the engine oil maintenance data
reset. This is not based on the monitoring of dirty
condition of the engine oil.
 Engine Oil Replacement Warning (U.S.A. only)
G13034
If the driving range exceeds 5,000 miles after the engine
oil maintenance data is reset, the master warning light
comes on, a warning tone sounds and the above message
appears.
This message indicates that the engine oil should be replaced
as soon as possible. If the message appears, it is
recommended to inspect the engine oil with the engine switch
off. For details about inspection, see “Checking the engine oil
level” on page 530.
If the engine oil level is low, engine oil should be replaced.
Have it replaced at your Lexus dealer.
After the engine oil replacement, reset the engine oil
maintenance data and make sure the “OIL MAINT RESET”
appears on the display.

Tire Pressure Warning
G13025
When the low tire inflation pressure is detected while
driving, the tire pressure warning light and master
warning light come on, and the above message appears.
Adjusting the tire inflation pressure will turn off the warning
message. If the message remains on, have your vehicle
checked by your Lexus dealer.
G13024
This message indicates the tire pressure warning system is
initialized. After replacing the tires or wheels, adjust all 4 tires
to specified tire inflation pressure and initialize the tire pressure
warning system. To initialize the system, start the engine and
push the tire pressure warning reset switch for longer than 3
seconds with the vehicle stopped. The above message
appears.
G13026
If there is a problem in the tire pressure warning system,
the tire pressure warning light blinks and master warning
light comes on, and the above message appears.
The tire pressure warning light system is not working properly.
In this case, it is probable that a tire pressure warning valve and
transmitter is malfunctioning or the system is experiencing
signal interference. In the case of signal interference, the
warning message will turn off when the interference ends. If
the tire pressure warning light blinks and master warning light
comes on, and the above message appears frequently, have
your vehicle checked by your Lexus dealer.

vehicletovehicle distance because of a dirty millimeter
wave radar sensor or grille cover while the dynamic radar
cruise control is on, the master warning light comes on
and the “CRUISE” indicator light flashes. At this time a
warning tone sounds and the above message appears.
If this message appears, clean the sensor and grille cover with
a soft cloth and try setting the preset speed again. If the dirt
is removed without cleaning, the system will automatically
enter the “RADAR READY” mode. If the system does not enter
the “RADAR READY” mode even after cleaning or the
message remains on the display, the system might be
malfunctioning. Although it is no problem to continue driving,
contact your Lexus dealer.
G13074
If the system cannot easily measure the
vehicletovehicle distance because of the following
conditions while the dynamic radar cruise control is on,
the master warning light comes on, the “CRUISE”
indicator light flashes. At this time a warning tone sounds
and the above message appears.
 The driving pattern selector switch is set to the snow
position mode.
 It is determined that it is difficult to make a measurement
because of bad weather (such as extremely hot weather)
 The wipers are operated at high speed with the wiper lever
in the “AUTO” position

intermittent operation. (Including intermittent and stopped
wipers in the “AUTO” position)

96In the above conditions, press the control lever upward in the
“+ RES” direction and release it. The dynamic radar cruise
control will be restored, however, even after the weather
clears, if the setting operation cannot be performed or if the
warning message still appears, the system might have
malfunctioned. Although it is no problem to continue driving,
contact your Lexus dealer.
G13075
If the system malfunction is detected when dynamic radar
cruise control is in the “RADAR READY” mode or
operating, the master warning light comes on and the
“CRUISE” indicator light flashes. At this time a warning
tone sounds and the above message appears.
If this message appears, stop your vehicle in
a safe place, turn
the engine switch off, and then restart it to reset the system.
If the setting still cannot be made or the same message
appears again, the system might have malfunctioned.
Although it is no problem to continue driving, contact your
Lexus dealer.

control on, if the master warning light comes on, the
“CRUISE” indicator light flashes, “CHECK CRUISE
SYSTEM” appears on the multiinformation display and
the warning tone sounds, turn the engine switch off and
then on again. If the function is cancelled again after
setting or if settings cannot be made, the dynamic radar
