If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice.
If a towing service is not available in
an emergency, your vehicle may be
temporarily towed by a cable or chain
secured to either the emergency towing
eyelet on the front of the vehicle or the
right emergency towing eyelet on the
rear of the vehicle. Use extreme caution
when towing vehicles.
To install the towing eyelet, see
“—Installing towing eyelet” on page 180 in
this Section.
NOTICE
Only use specified towing eyelet;
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 hardsurfaced 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 a
vehicle. Avoid sudden starts or er-
ratic driving maneuvers which
would place excessive stress on the
emergency towing eyelets and tow-
ing cable or chain. The eyelets and
towing cable or chain may break
and cause serious injury or dam-
age.
In case of installing the eyelet on
the vehicle, be sure to tighten the
eyelet securely. If the eyelet is
loose, it may come off when towing
and result in death or serious injury
to the passenger in the front ve-
hicle or damage to that vehicle.
NOTICE
Use only a cable or chain specifi-
cally intended for use in towing ve-
hicles. Securely fasten the cable or
chain to the towing eyelets pro-
vided.
 Do not use the left rear eyelet. It is
not designed for towing.
Before towing, release the parking brake
and put the transmission in “N” (sequential
manual transmission) or in neutral (manual
transmission).
Sequential manual transmission: The
key must be in “ACC”.
Manual transmission: The key must be
in “ACC” (engine off) or “ON” (engine run-
ning).
Sequential manual transmission only:
After shifting the selector lever to the “N”
position, always make sure that the gear
is actually disengaged and is in neutral by
pushing the vehicle by hand or other
means. In case the gear can not be put
in neutral, turn the ignition switch from the
“OFF” to “ON” position, and operate the
selector lever once from “N” to “S” or “R”,
then back to “N” again. Then turn the
ignition switch from the ”ON” to “OFF”
position. These procedures may help put
the gear in neutral. If the gear still can
not be put in neutral, you can not tow
with cables or chains.

CAUTION
If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual.
Do not tow with a cable or chain
when the ignition switch is in the
“ON” position and/or when the
transmission is not in the neutral
gear position. Otherwise, you may
be involved in an unexpected acci-
dent.
