ÐFront seat belt pretensioners
The driver and front passenger 's seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact.
When the airbag sensor detects the shock
of a severe frontal impact, the front seat
belt is quickly drawn back in by the re-
tractor so that the belt snugly restrains
the front seat occupants.
The seat belt pretensioners are activated
even with no passenger in the front seat.
Collisions occurring at certain speeds and
angles may cause the seat belt preten-
sioners and SRS airbags not to operate
all together.This indicator comes on when the igni-
tion key is turned to the ACCº or
ONº position. It goes off after about
6 seconds. This means the front seat
belt pretensioners are operating proper-
ly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, inflators, front
seat belt pretensioner assemblies, warning
light, interconnecting wiring and power
sources. (For details, see Service remind-
er indicators and warning buzzersº in Sec-
tion 1- 5.)The front seat belt pretensioner system
mainly consists of the following compo-
nents and their locations are shown in the
illustration.
1. Front airbag sensors
2. SRS warning light
3. Front seat belt pretensioner assemblies
4. Airbag sensor assembly
The front seat belt pretensioners are con-
trolled by the airbag sensor assembly. The
airbag sensor assembly consists of a saf-
ing sensor and airbag sensor.

When the front seat belt pretensioners are
activated, an operating noise may be
heard and a small amount of smoke- like
gas may be released. This gas is harm-
less and does not indicate that a fire is
occurring.
Once the front seat belt pretensioners
have been activated, the seat belt retrac-
tors remain locked.
CAUTION
Do not modify, remove, strike or open
the front seat belt pretensioner as-
semblies, airbag sensor or surround-
ing area or wiring. Doing any of
these may cause sudden operation of
the front seat belt pretensioners or
disable the system, which could re-
sult in death or serious injury.
Failure to follow these instructions
can result in death or serious inju-
ries.
NOTICE
Do not perform any of the followingchanges without consulting yourToyota dealer. Such changes caninterfere with proper operation of the
front seat belt pretensioners in somecases.

Installation of electronic devices
such as a mobile two- way radio,
cassette tape player or compactdisc player

CAUTION
A driver or front passenger too close
to the steering wheel or dashboard
during airbag deployment can be
killed or seriously injured. Toyota
strongly recommends that:

The driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.

The front passenger sit as far back
as possible from the dashboard.

All vehicle occupants be properly
restrained using the available seat
belts.This indicator comes on when the igni-
tion key is turned to the ACCº or
ONº position. It goes off after about
6 seconds. This means the SRS airbags
are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, inflators, front
seat belt pretensioner assemblies, warning
light, interconnecting wiring and power
sources. (For details, see Service remain-
der indicators and warning buzzersº in
Section 1- 5.)The SRS airbag system is designed to
activate in response to a severe frontal
impact within the shaded area between
the arrows in the illustration.
The SRS airbags will deploy if the severi-
ty of the impact is above the designed
threshold level, comparable to an approxi-
mate 25 km/h (15 mph) collision in the
U.S.A. and 30 km/h (18 mph) collision in
Canada when impacting straight into a
fixed barrier that does not move or de-
form.
If the severity of the impact is below the
above threshold level, the SRS airbags
may not deploy.

SRS side airbags
The SRS (Supplemental Restraint Sys-
tem) side airbags are designed to pro-
vide further protection for occupants in
the following seats in addition to the
primary safety protection provided by
the seat belts.

Vehicles with bucket front seatsÐThe
SRS side airbags are designed to pro-
tect the driver and front passenger.

Vehicles with bench type front seatsÐ
The SRS side airbags are designed to
protect the driver and right- front pas-
senger. They are not designed to pro-
tect occupant in the center position.In response to a severe side impact, the
SRS side airbags work together with the
seat belts to help reduce injury by inflat-
ing. The SRS side airbags help to reduce
injuries mainly to the driver's or front pas-
senger 's chest. The SRS side airbag on
the passenger seat is activated even with
no passenger in the front seat.
Be sure to wear your seat belt properly.
CAUTION
SRS side airbags inflate with consid-
erable force. To avoid potential death
or serious injury when they inflate,
the driver and front passenger must:

Wear their seat belts properly

Remain properly seated with their
back upright and against the seat at
all times.
This indicator comes on when the igni-
tion key is turned to the ACCº or
ONº position. It goes off after about
6 seconds. This means the SRS side
airbags are operating properly.

NOTICE

Do not crank for more than 30 se-conds at a time. This may overheatthe starter and wiring systems.

Do not race a cold engine.

If the engine becomes difficult tostart or stalls frequently, have the
engine checked immediately.

Always slow down in gusty crosswinds.
This will allow you much better control.

Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp- edged objects and
other road hazards. Failure to do so
can lead to severe tire damage result-
ing in tire bursts.

When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in Pº. If necessary, block the
wheels.

Washing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.
CAUTION

Before driving off, make sure the
parking brake is fully released and
the parking brake reminder light is
off.

Do not leave your vehicle unat-
tended while the engine is running.

Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.

To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.

Be careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking, could cause
the vehicle to spin or skid.

Never tow a trailer without using a
safety chain securely attached to
both the trailer and the vehicle. If
damage occurs to the coupling unit
or hitch ball, there is danger of the
trailer wandering over into another
lane.
TIRES

Ensure that your vehicle's tires are
properly inflated. See Section 7- 2 for
instructions.

The trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the total
trailer weight.
TRAILER LIGHTS

Trailer lights must comply with federal,
state/provincial and local regulations.
See your local recreational vehicle
dealer or rental agency for the correct
type of wiring and relays for your trail-
er. Check for correct operation of the
turn signals and stop lights each time
you hitch up. Direct splicing may dam-
age your vehicle's electrical system
and cause a malfunction of your lights. BREAK- IN SCHEDULE

Toyota recommends that you do not
tow a trailer with a new vehicle or a
vehicle with any new power train com-
ponent (engine, transmission, differen-
tial, wheel bearing, etc.) for the first
800 km (500 miles) of driving.
MAINTENANCE

If you tow a trailer, your vehicle will
require more frequent maintenance due
to the additional load. For this informa-
tion, please refer to the scheduled
maintenance information in the Sched-
uled Maintenance Guideº or Owner 's
Manual Supplementº.

Retighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving.
PRE- TOWING SAFETY CHECK

Check that your vehicle remains level
when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle has
an abnormal nose- up or nose- down
condition, and check for improper
tongue load, overload, worn suspension
or other possible causes.

Make sure the trailer cargo is securely
loaded so that it can not shift.

Check that your rear view mirrors con-
form to any applicable federal, state/
provincial or local regulations. If not,
install the rear view mirrors required
for towing purpose.
TRAILER TOWING TIPS
When towing a trailer, your vehicle will
handle differently than when not tow-
ing. The three main causes of vehicle-
trailer accidents are driver error, exces-
sive speed and improper trailer loading.
Keep these in mind when towing:

Before starting out, check operation of
the lights and all vehicle- trailer connec-
tions. After driving a short distance,
stop and recheck the lights and con-
nections. Before actually towing a trail-
er, practice turning, stopping and back-
ing with a trailer in an area away from
traffic until you learn the feel.

Before making these checks, make sure
you have followed the correct starting
procedure given in How to start the
engineº in Section 3 and that you have
sufficient fuel. If your vehicle is equipped
with the engine immobiliser system, also
check whether the other keys will start the
engine. If they work, your key may be
broken. Have the key checked at your
Toyota dealer. If none of your keys work,
the system is possibly broken. Call your
Toyota dealer. (See Keys (with engine
immobiliser system)º in Section 1- 2.)
If the engine is not turning over or is turn-
ing over too slowlyÐ1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked, the battery
is discharged. You may try jump start-
ing. See (c) Jump startingº for further
instructions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call a Toyota dealer or qualified repair
shop.NOTICE

converter may overheat and become afire hazard.
If the engine turns over at its normal
speed but will not startÐ
1. The engine may be flooded because of repeated cranking. See (b) Starting a
flooded engineº for further instructions.
2. If the engine still will not start, it needs adjustment or repair. Call a Toyota
dealer or qualified repair shop.
(b) Starting a flooded engine
If the engine will not start, your engine
