—After changing wheels
11. Check the air pressure of the re- placed tire.
Adjust the air pressu re to the specifi-
cation designated on page 299 in
Section 8. If the pressure is lower,
drive slowly to the nearest service
station and fill to the correct pressure.
Do not forget to reinstall the tire infla-
tion valve cap as dirt and moisture
could get into th e valve core and
possibly cause air leakage. If the cap
is missing, have a new one put on as
soon as possible.
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 299 in Sec-
tion 8 with a torque wrench. And have
a technician repair the flat tire.

location to reduce the possibility
of personal injury during a colli-
sion or sudden braking.

cause body damage.
—Emergency towing
PS41524
Front
PS41525
Rear
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 to
the right emergency towing eyelet un-
der the rear of the vehicle. Use extreme
caution when towing vehicles.
Vehicles with an automatic transmis-
sion, use only the front towing eyelet
when towing your vehicle.
To install the front towing eyelet, see
“—Installing front towing eyelet” on page
243 in this Section.
NOTICE
Only use specified towing eyelet;
otherwise your vehicle may be dam-
aged.
 Vehicles with an automatic trans-
mission, never tow a vehicle from
the rear with four wheels on the
ground. This may cause serious
damage to the transmission.

2432006 YARIS HATCHBACK from Aug. ’05 Prod. (OM52703U)
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 eyelets and towing cable or
chain. The eyelets and towing cable
or chain may break and cause serious
injury or damage.
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 eyelet provided.
 Do not use the left rear eyelet. It is
not designed for towing.
Before towing, release the parking brake
and put the transmission in neutral (manu-
al) or “N” (automatic). The key must be
in “ACC” (engine off) or “ON” (engine run-
ning).
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.
PS41526
1. Remove the front towing eyelet cover
on the front bumper, using a flathead
screwdriver which is wrapped with a
cloth.

3. Tighten the front towing eyelet securelyby a wheel nut wrench.
CAUTION
When installing the eyelet on the ve-
hicle, be sure to tighten the front
eyelet securely. If the eyelet is loose,
it may come off when being towed
and result in death or serious injury.
