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 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 the 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
Select Octane Rating 87 (Research
Octane Number 91) or higher. For
improved vehicle performance, the use
of premium unleaded gasoline with an
Octane Rating of 91 (Research Octane
Number 96) or higher is recommended.
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, now and then, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is no need
of concern.
