Deviation
The direction display deviates from the
true direction determined by the
earth’s magnetic field. The amount of
deviation varies depending on the geo-
graphic position of the vehicle.
If you cross over one of the map boundar- ies shown in illustration, the compass will
deviate.
To obtain higher precision or perfect cali-
bration, refer to “D eviation calibration”.
■
Deviation calibration
1 Stop the vehicle.WARNING■
While driving the vehicle
Do not adjust the display. Adjust the dis-
play only when the vehicle is stopped. NOTICE■
To avoid compass malfunctions
Do not place magnets or any metal
objects near the inside rear view mirror.

Routine tire inflation pressure checks
The tire pressure warning system does not
replace routine tire inflation pressure
checks. Make sure to check tire inflation
pressure as part of your routine of daily
vehicle checks.
Your vehicle is equipped with a tire
pressure warning system that uses tire pressure warning valves and transmit-
ters to detect low ti re inflation pressure
before serious problems arise.
 If the tire pressure drops below a
predetermined level, the driver is
warned by a warning light.
( → P.370)
 The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display.

initialization again. ■
Warning performance of the tire pres-
sure warning system
The warning of the tire pressure warning
system will change in accordance with the
conditions under which it was initialized. For
this reason, the system may give a warning
even if the tire pressure does not reach a
low enough level, or if the pressure is higher
than the pressure that was adjusted to when
the system was initialized. ■
When initialization of the tire pressure
warning system has failed
Initialization ca n be completed in a few min-
utes. However, in the following cases, the
settings have not been recorded and the
system will not operate properly. If repeated
attempts to record tire inflation pressure
settings are unsuccessf ul, have the vehicle
inspected by your Lexus dealer. ●
