The seat belt pretensioner system con-
sists mainly of the following components,
and their locations are shown in the il-
lustration.1. Front airbag sensors
2. SRS warning light
3. Seat belt pretensioner assemblies
4. Airbag sensor assembly
The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor. When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of non
−toxic gas may
be released. This does not indicate that
a fire is occurring. This gas is normally
harmless.
Once the seat belt pretensioners have
been activated, the seat belt retractors
remain locked.
CAUTION
Do not modify, remove, strike or
open the seat belt pretensioner as-
semblies, airbag sensor or sur-
rounding area or wiring. Failure to
follow these instructions may pre-
vent the seat belt pretensioners
from activating correctly, cause sud-
den operation of the system or dis-
able the system, resulting in death
or serious injury.
Do not use tires or wheels other
than the manufacturer ’s recom-
mended size. Such a use may cause
the curtain shield airbags and seat
belt pretensioners to inflate acci-
dentally, resulting in death or seri-
ous injury. For details, see “Check-
ing and replacing tires” on page
304.
Do not place luggage heavier than
specified on the roof luggage carri-
er. Such luggage may cause the
curtain shield airbags and seat belt
pretensioners to inflate accidentally,
resulting in death or serious injury.
For details, see “Roof luggage car-
rier” on page 202.
Do not modify or change the sus-
pension system. Such changes may
cause the curtain shield airbags to
inflate accidentally, resulting in
death or serious injury.
Failure to follow these instructions
can result in death or serious inju-
ries. Consult your Toyota dealer
about any repair and modification.

hicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on for more than 6
seconds or flashes.
The light comes on or flashes while
driving.If the light stays on, it indicates that the
driver and passenger airbags have a prob-
lem. If the light flashes, the side and cur-
tain shield airbags and/or the seat belt
pretensioners have a problem.
(i) “ABS” Warning Light
The light comes on when the ignition
key is turned to the “ON” position. If
the antilock brake system and the
brake assist system work properly, the
light turns off after a few seconds.
Thereafter, if either of the systems mal-
functions, the light comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti
−lock brake system, the brake assist
system, the vehicle stability control sys-
tem and/or active traction control system
do/does not operate, but the brake system
still operates conventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces. If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components monitored by
the warning light system. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.

246
CAUTION
If the total trailer weight exceeds
453 kg (1000 lb.), trailer brakes are
required.
Never tap into your vehicle’s hy-
draulic system as it would lower its
braking effectiveness.
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. Adjust the tire infla-
tion pressure indicated below:
tire inflation pressure, kPa (psi)Front 220 (32)
Rear 240 (35)
See Section 7 −2 and Section 8 for in-
structions.
The trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the total
trailer weight.
TRAILER LIGHTS
Your vehicle is equipped with a wire
harness stored in the rear end under
body. Your vehicle is fitted with a sock-
et for trailer lights under the rear
bumper. Use either of them to connect
and operate the trailer lights. However,
the trailer lights must comply with fed-
eral, state/provincial and local regula-
tions. See your local recreational ve-
hicle dealer or rental agency for the
correct type of wiring and relays for
your trailer. Check for correct operation
of the turn signals and stop lights each
time you hitch up. Direct splicing may
damage your vehicle’s electrical system
and cause a malfunction of your lights.
