NOTICE
Only use specified towing hook;
otherwise your vehicle may be dam-
aged.
A driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done only
on hard- surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, drive train, steering and
brakes must all be in good condition.
CAUTION
Use extreme caution when towing ve-
hicles. Avoid sudden starts or erratic
driving maneuvers which would place
excessive stress on the emergency
towing hook and towing cable or
chain. The hook and towing cable or
chain may break and cause serious
injury or damage.
NOTICE
Use only a cable or chain specifically
intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing hook provided.
Before towing, release the parking brake
and put the transmission in neutral (manu-
al) or Nº (automatic) and the transfer in
H2º (four- wheel drive models). The key
must be in ACCº (engine off) or ONº
(engine running).
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.

securely or push the UNLOCKº switch.To unlock: Push the UNLOCKº switch
once to unlock the driver 's door alone.

and the parking lights and tail lights flash
twice.

side doors and back door will be automati-
cally locked again.
If the LOCKº or UNLOCKº switch is kept
pressed in, the locking or unlocking opera-
tion is not repeated. Release the button
and then push again.
The volume of beep sound can be
changed. Contact your Toyota dealer for
details if you require it.
