■SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag
sensors, side and curtain shield airbag sensor assemblies, curtain shield air-
bag sensor assemblies, driver’s seat position sensor, driver’s seat belt
buckle switch, front passenger occupant classification system, AIR BAG ON
and AIR BAG OFF indicator lights, front passenger’s seat belt buckle switch,
passenger airbag off switch (Regular C ab models), front seat belt preten-
sioner assemblies, RSCA OFF indicator light, inflators, interconnecting wir-
ing and power sources. ( P. 600)
■ If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, and parts of the front and rear pillars and roof
side rail, may be hot for several minutes. The airbag itself may also be
hot.
● The front windshield may crack.
■ Operating conditions (front airbags)
● The SRS front airbag will deploy in the event of an impact that exceeds
the set threshold level (the level of force corresponding to an approxi-
mately 12-18 mph [20-30 km/h] frontal collision with a fixed wall that does
not move or deform).
However, this threshold velocity will be considerably higher if the vehicle
strikes an object, such as a parked vehicle or sign pole, which can move or
deform on impact, or if the vehicle is involved in an underride collision (e.g.
a collision in which the front of the vehicle “underrides”, or goes under, the
bed of a truck, etc.).
● It is possible that in some collisions where the forward deceleration of the
vehicle is very close to the designed threshold level, the SRS front air-
bags and the seat belt pretensioners may not activate together.
● The SRS front passenger airbag will not activate if there is no passenger
sitting in the right front passenger seat. However, the front passenger air-
bag may deploy if luggage is put in the seat, or the seat belt is fastened,
even if the seat is unoccupied. ( P. 135)

Trailer Tongue Weight and Trailer Kingpin Weight
● A recommended tongue weight or kingpin weight varies in accor-
dance with the types of trailers or towing as described below.
● To ensure the recommended values shown below, the trailer must
be loaded by referring to the following instructions.
1. Conventional Towing
The gross trailer weight should be distributed so that the tongue
weight is 9% to 11%. (Tongue Weight/Gross trailer weight x 100
= 9% to 11%)
Gross trailer weight
Tongue Weight
If using a weight distributing hitch when towing, return the front
axle to the same weight as before the trailer connection.
If front axle weight cannot be measured directly, measure the
front fender height above th e front axle before connection.
Adjust weight distributing hitch torque until front fender is
returned to the same height as before connection.
Do not reduce front fender height below original measurement.
The gross trailer weight, gross axle weight and tongue weight
can be measured with platform scales found at a highway
weighing station, building supply company, trucking company,
junk yard, etc.

If your vehicle needs to be towed
Before towingThe following may indicate a problem with your transmission. Contact
your Toyota dealer before towing.
● The engine is running, but the vehicle will not move.
● The vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available, in an emergency your vehicle may be
temporarily towed using a cable or chain secured to the emergency
towing eyelet. This should only attempted on hard, surfaced roads for
short distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
Type A Towing eyelet
If towing is necessary, we recommend having your vehicle towed by
your Toyota dealer or a commerci al towing service, using a lift-type
truck or a flat bed truck.
Use a safety chain system for all to wing, and abide by all state/pro-
vincial and local laws.
The wheels and axle on the groun d must be in good condition.
If they are damaged, use a towing dolly or flat bed truck.

4WD models
We recommend the use of a tow-
ing dolly under the front wheels.
When not using a towing dolly,
turn the engine switch to the ACC
position, shift the shift lever to N
and put the front wheel drive con-
trol switch in 2WD.
Using a flat bed truck
If your Toyota is transported by a
flat bed truck, it should be tied
down at the locations shown in
the illustration.
NOTICE
■To prevent damage to the vehicle
●Do not tow the vehicle with the key removed or in the LOCK position.
The steering lock mechanism is not strong enough to hold the front wheel
straight.
● When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed.
