Leak detection pump
This pump performs fuel evaporation leakage check.
This check is done several 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.
On pavement and off roaddriving tips
This vehicle belongs to the ut ility vehicle class. Utility
vehicles have a significantly higher rollover rate than
other types of vehicles. This vehicle will handle and
maneuver differently from an ordinary passenger car be-
cause 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 feature causes this type of vehicle to be
more likely to rollover. 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 precautions” on page 224 and
“Off −road driving precautions” on page 254.

TESTING THE SYSTEM1. Open all the windows.
2. Set the system as described above. The side doors and back door should
be locked with the key or wireless re-
mote control key. Be sure to wait until
the indicator light goes off or starts
flashing.
3. Unlock any side door or back door from the inside. The system should ac-
tivate the alarm.
4. Stop the alarm as described above.
5. Repeat this operation for the other doors, back door and hood. When test-
ing the hood, also check that the sys-
tem is activated when the battery ter-
minal is disconnected and then
reconnected.
If the system does not work properly,
have it  checked by  your Toyota dealer.
Fuel tank cap
12C503
This indicates that the fuel filler door
is on the left side of your vehicle.1. To open the fuel filler door, pull the lever.
When refueling, turn off the engine.
CAUTION
Do not smoke, cause sparks or al-
low open flames when refueling.
The fumes are flammable.
When opening the cap, do not re-
move the cap quickly. In hot weath-
er, fuel under pressure could cause
injury by spraying out of  the filler
neck if  the cap is suddenly re-
moved.

NOTICE
Do not put unevenly weighed ob-
jects on the seat and do not stick
sharp objects (needles, nails, etc.)
into the seat.
 When cleaning the seats, do not
use organic substances (paint thin-
ner, benzine, alcohol, gasoline,
etc.). They may damage the heater
and seat surface.
 To prevent the battery from being
discharged, turn the switch off
when the engine is not running.
Toyota strongly urges that the driver and
passengers in the vehicle be properly re-
strained at all times with the seat belts
provided. Failure to do so could increase
the chance of injury and/or the severity of
injury in accidents.
The seat belts provided for your vehicle
are designed for people of adult size,
large enough to properly wear them.
Child.  Use a child restraint system ap-
propriate for the child until the child be-
comes large enough  to properly  wear the
vehicle’s seat belts. (For details, see
“Child restraint” on page 78.)
If a child is too large for a child restraint
system, the child s hould sit in the rear
seat and must be restrained using the
vehicle’s seat belt. According to accident
statistics, the child is safer when properly
restrained in the rear seat than in the
front seat.
If a child must sit in the front seat, the
seat belts  should be worn properly. If an
accident occurs and the seat belts are not
worn properly, the force of the rapid infla-
tion of the airbag may  cause death or
serious injury to the child. Do not allow any children to stand up or
kneel on either rear or front seats. An
unrestrained child could suffer serious in-
jury or death during emergency  braking or
a collision. Also, do not let the child sit
on your lap. Holding a child in your arms
does not provide sufficient restraint.
Pregnant woman. 
Toyota recommends the
use of a seat belt. Ask your doctor for
specific recommendations. The lap belt
should be worn securely and as low as
possible over the hips and not  on the
waist.
Injured person.  Toyota recommends the
use of a seat belt. Depending on the inju-
ry, first check with your doctor for specific
recommendations.

NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not  continue driving with an
overheated engine. See “If your ve-
hicle overheats” on page 274.
Engine oil pressure gauge 
Idling
Normal
driving
The engine oil pressure gauge indicates
engine oil pressure when the ignition
switch is on. Check it while driving to
make sure the needle is in the proper
range.
If the engine oil pressure should stay be-
low the normal range, pull off the road to
a safe place and  stop the engine immedi-
ately. Call a Toyota dealer or qualified
repair shop for assistance.
Engine oil pressure may not build up
when the engine oil level is  too low. The
engine oil pressure gauge is not designed
to indicate oil level, and the engine oil
level must be checked using the level
dipstick.
NOTICE
Do not drive the vehicle with the en-
gine oil pressure below the normal
range until the cause is fixed—it may
ruin the engine.

Vo l t m e t e r 
The voltmeter tells whether the battery
is charged or discharged. Check it
while the engine is running—the needle
should always indicate as shown above.
If the needle reads below or above the
normal range while the engine is running,
it indicates the charging system needs im-
mediate repair.
However, it is normal for the needle to
drop below the normal range during en-
gine starting.
Tachometer 
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to prevent
engine over-revving.
Driving with the engine running too fast
causes excessive engine wear  and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.

(a) Brake System Warning Light andBuzzer
This light comes on in the following cases
when the ignition key is in the “ON” posi-
tion.
When the parking brake is applied...
This light comes on for a few seconds
when the ignition key is in the “ON” posi-
tion even after the parking brake is re-
leased.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
When the hydraulic brake booster
fails...
If the hydraulic booster causes an problem
resulting in poor braking performance, the
warning light comes on and buzzer sounds
continuously. Have your vehicle checked at your
Toyota dealer in the following cases:
The light does not come on even if the
parking brake is applied when the igni-
tion key is in the “ON” position.
The light does not come on even if the
ignition key is turned on with the park-
ing brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If any of the following conditions oc-
cur, immediately stop your vehicle at
a safe place and contact  your Toyota
dealer.
The light does not turn off even
after the parking brake is released
while the engine is running.
The warning buzzer comes on to-
gether with the warning light.
In either case, this can indicate that
the brakes may not work properly and
your stopping distance will become
longer. Depress the brake pedal firmly
and bring the vehicle to an immediate
stop.
The brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the anti lock
brake system will fail but also the

the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is  stopped and
the ignition key is turned to “ACC” or
“LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state emis-
sion inspection if the malfunction indicator
lamp remains on. Contact your Toyota
dealer to check your vehicle’s emission
control system and OBD (On −Board Diag-
nostics) system before taking your vehicle
for the inspection.

is turned to the “ON” position. If the tire
pressure warning system works properly
and tire inflation pressure is appropriate,
the light goes off after a few seconds.
This light comes on or flashes in the fol-
lowing cases when the ignition key is
turned to the “ON” position.
When the low tire inflation pressure
is detected while driving...
If any tire has low inflation pressure,
the light comes on. The light goes off after the tire inflation
pressure is adjusted to a specified lev-
el.
When initializing the system...
If initialization is completed,  the light
blinks three times.
