Onpavement and offroad
driving tips
This vehicle belongs to the utility vehicle class. Utility ve-
hicles have a significantly higher rollover rate than other
types of vehicles. This vehicle will handle and maneuver
differently from an ordinary passenger car because it is
designed for off −road use also. In addition, this vehicle
has a higher ground clearance and center of gravity than
that of an ordinary passenger car. This vehicle design fea-
ture causes this type of vehicle to be more likely to rol-
lover. Failure to operate this vehicle correctly may result in
loss of control, accidents or vehicle rollover causing death
or serious injury. Be sure to read “Off −road vehicle precau-
tions” on page 290 in Section 2 and “Off −road driving pre-
cautions” on page 320 in Section 3.
Leak detection pump
(2.4 L 4cylinder [2AZFE]
engine)
This pump performs fuel evaporation leakage check. This
check is done approximately five hours after the engine is
turned off. So you may hear sound coming from under-
neath the luggage compartment for several minutes. It
does not indicate a malfunction.

Always slow down in gusty cross-
winds. Because of its profile and
higher center of gravity, your ve-
hicle is more sensitive to side
winds than an ordinary passenger
car. Slowing down will allow you to
have better control.
When driving offroad or in rugged
terrain, do not drive at excessive
speeds, jump, make sharp turns,
strike objects, etc. This may cause
loss of control or vehicle rollover
causing death or serious injury. You
are also risking expensive damage
to your vehicle’s suspension and
chassis.
Do not drive horizontally across
steep slopes. Driving straight up or
straight down is preferred. Your ve-
hicle (or any similar offroad ve-
hicle) can tip over sideways much
more easily than forward or back-
ward.
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
2.4 L 4cylinder (2AZFE) engine: Se-
lect Octane Rating 87 (Research Octane
Number 91) or higher.
3.3 L V6 (3MZFE) engine: Select Oc-
tane Rating 87 (Research Octane Num-
ber 91) or higher. For improved vehicle
performance, use premium unleaded
gasoline with an Octane Rating of 91
(Research Octane Number 96) or higher.
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. GASOLINE CONTAINING DETERGENT
ADDITIVES
Toyota recommends the use of gasoline
that contains detergent additives to
avoid buildup of engine deposits.
However, all gasoline sold in the U.S.
contains detergent additives to keep clean
and/or clean intake systems.
QUALITY GASOLINE
Automotive manufacturers in the U.S.,
Europe and Japan have developed a
specification for quality fuel named
WorldWide Fuel Charter (WWFC) that
is expected to be applied world wide.
The WWFC consists of four categories
that depend on required emission lev-
els. In the U.S., category 3 or 4 has
been adopted. The WWFC improves air
quality by providing for better emis-
sions in vehicle fleets, and customer
satisfaction through better vehicle per-
formance.
CLEANER BURNING GASOLINE
Cleaner burning gasoline, including re-
formulated gasoline that contains oxy-
genates such as ethanol or MTBE is
available in many areas.
Toyota recommends the use of cleaner
burning gasoline and appropriately blended
reformulated gasoline. These types of gas-
oline provide excellent vehicle perfor-
mance, reduce vehicle emissions, and im-
prove air quality.
OXYGENATES IN GASOLINE
Toyota allows the use of oxygenate
blended gasoline where the oxygenate
content is up to 10% ethanol or 15%
MTBE. If you use gasohol in your
Toyota, be sure that it has an octane
rating no lower than 87.
Toyota does not recommend the use of
gasoline containing methanol.
