CALIBRATING THE COMPASS (circling
calibration)
Sometimes  the direction display  on the
compass may not change after a turn. In
this case, the compass needs to be cali-
brated.
To calibrate the compass manually, do the
following;1. Stop the vehicle in a level place and switch the display to the outside tem-
perature. (To switch to this mode, see
“—Outside temperature and cruise in-
formation display” on page 376.) 2. Push and hold both the “MODE” and
“E/M” buttons simultaneously for 10
seconds until the “CAL” indication ap-
pears on the compass display. (At this
time, the compass display is locked in
“N”.)3. Drive the vehicle in a circle at 8 km/h(5 mph) or less. If there is not enough
space to drive in a circle, drive around
the block.
When the “CAL” indication goes off and
the compass returns to the normal mode,
calibration is complete.
If you want to restart the calibration be-
fore it is complete, push both of the
“MODE” and “E/M” buttons simultaneously
for 10 seconds again.

range depending on the fluid temperature.
See page 522 in Section 7−2 for addition-
al information.
Exhaust system
If  you notice any change in the sound of
the exhaust or smell exhaust fumes, have

straints move up and down  smoothly and
that the locks hold securely in any latched
position. For folding
−down rear seatbacks
and detachable  second seats,  check  that

Using any other size or type of tire
may seriously affect handling, ride,
speedometer/odometer calibration,
ground clearance, and clearance be-
tween the body and tires or snow
chains.
Check that the maximum load of the
replaced tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR)
of either the front axle or the rear
axle, whichever is greater. As for the
maximum load of the tire, see the load
limit at maximum cold tire inflation
pressure mentioned on the sidewall
of the tire, and as for the Gross Axle
Weight Ratings (GAWR), see the Cer-
tification Label.
For details about the side wall of the
tire and the Certification Label, see
pages 431 and 433.
CAUTION
Observe the following instruc-
tions. Otherwise, an accident
may occur resulting in death or
serious injuries.
Do not mix radial, bias belted,
or bias ply tires on your ve-
hicle, as this may cause dan-
gerous handling characteris-
tics resulting in loss of control.
 Do not use tires other than the
manufacturer’s recommended
size, as this may cause danger-
ous handling characteristics
resulting in loss of control.
 All wheel drive models:
Do not use tires of different
brands, sizes, construction or
tread patterns, as this may
cause dangerous handling
characteristics resulting in
loss of control.Toyota recommends all four tires,
or at least both of the front or rear
tires be replaced at a time as a set.
See “If you have a flat tire” on page
471 in Section 4 for tire change proce-
dure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect ve-
hicle handling and tire life. Wheels
can get out of balance with regular
use and should therefore be balanced
occasionally.
When replacing a tubeless tire, the
air valve should also be repl aced
w i t h a new on e.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have rotated your tires.
See “Tire pressure warning sys-
tem” on page 214 in Section 1 7.
