CALIBRATING THE COMPASS (circling
calibration)
Sometimes the direction display on the
compass may not change after a turn. To
rectify this, stop the vehicle and push and
hold the both personal light switches until
“C” appears on the display.
If “C” appears on the display because of
a drastic change in the magnetic field,
perform circling calibration.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.
After driving 1 to 3 circles in the above
method, calibration is completed when the
direction is shown on the display.
If calibration cannot be performed because
of the magnetized vehicle etc., take your
vehicle to Toyota dealer.Perform circling calibration just after
you have purchased your Toyota. And
then always perform circling calibration
after the battery has been removed, re-
placed or disconnected.
Do not perform circling calibration of
the compass in a place where the
earth’s magnetic field is subject to in-
terference by artificial magnetic fields
(underground parking, under a steel
tower, between buildings, roof parking,
near a crossing, near a large vehicle,
etc.).
During calibration, do not operate elec-
tric systems (moon roof, power win-
dows, etc.) as they may interfere with
the calibration.
CAUTION
When doing the circling calibration,
be sure to secure a wide space,
and watch out for people and ve-
hicles in the neighborhood. Do not
violate any local traffic rules while
performing circling calibration.
Do not adjust the display while the
vehicle is moving. Be sure to adjust
the display only when the vehicle is
stopped.

Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break−in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of
your vehicle:
Avoid full throttle acceleration when
starting and driving.
Avoid racing the engine.
Try to avoid hard stops during the first
300 km (200 miles).
Do not drive slowly with the manual
transmission in a high gear.
Do not drive for a long time at any
single speed, either fast or slow.
Do not tow a trailer during the first 800
km (500 miles). FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mix
−ups, your
Toyota has a smaller fuel tank opening.
The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard nozzle on pumps with leaded gas will
not.
At a minimum, the gasoline you use
should meet specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5 −M93
in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three
way catalytic converter to lose its ef-
fectiveness and the emission control
system to function improperly. Also,
this can increase maintenance costs.
OCTANE RATING
1ZZ FE engine—
Select Octane Rating 87 (Research Oc-
tane Number 91) or higher.
2ZZ GE engine—
Select premium unleaded gasoline with
an Octane Rating of 91 (Research Oc-
tane Number 96) or higher for optimum
engine performance.
Use of unleaded gasoline with an octane
rating or research octane number lower
than stated above will cause persistent
heavy knocking. If it is severe, this will
lead to engine damage.
If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady speed on level roads, consult your
Toyota dealer.
However, occasionally, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is normal
and there is no need for concern.
