CAUTION
Never use oil or grease on the
bolts or nuts. Doing so may lead
to overtightening the nuts and
damaging the bolts. The nuts
may loosen and the wheels may
fall off, which could cause a seri-
ous accident. If there is oil or
grease on any bolt or nut, clean
it.
—Lowering your vehicle
SY41018
8. Lower the vehicle completely
and tighten the wheel nuts.
Turn the jack handle counterclock-
wise to lower the vehicle.
Use only the wheel nut wrench to
tighten the nuts. Do not use other
tools or any additional leverage other
than your hands, such as a hammer,
pipe or your foot. Make sure the
wrench is securely engaged over the
nut.
Tighten each nut a little at a time in
the order shown. Repeat the process
until all the nuts are tight.
CAUTION
When lowering the vehicle,
make sure all portions of your
body and all other persons
around will not be injured as
the vehicle is lowered to the
ground.
Have the wheel nuts tightened
with torque wrench to 103 N·m
(10.5 kgf·m, 76 ft·lbf), as soon
as possible after changing
wheels. Otherwise, the nuts
may loosen and the wheels
may fall off, which could cause
a serious accident.

—After changing wheels
9. Check the air pressure of the re-
placed tire.
Adjust the air pressure to the specifi-
cation designed on page 215. 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 the valve core and
possibly cause air leakage. If the cap
is missing, have a new one put on as
soon as possible.
10. Restow all the tools, jack and
flat tire securely.
To secure the flat tire, use the flat tire
bolt in the tool bag. Stow the spare
tire bolt into the tool bag.
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 215 with a
torque wrench and have a technician
repair the flat tire.CAUTION
Before driving, make sure all the
tools, jack and flat tire are se-
curely in place in their storage
location to reduce the possibility
of personal injury during a colli-
sion or sudden braking.
If your vehicle becomes stuck in snow,
mud, sand, etc., then you may attempt
to rock the vehicle free by moving it
forward and backward.
CAUTION
Do not attempt to rock the vehicle
free by moving it forward and back-
ward if people or objects are any-
where near the vehicle. During the
rocking operation the vehicle may
suddenly move forward or backward
as it becomes unstuck, causing injury
or damage to nearby people or ob-
jects.

—Emergency towing
Front
Rear
If towing is necessary, we recommend
you to have it done by your Scion deal-
er or a commercial tow truck service.
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 or the rear of the
vehicle. Use extreme caution when tow-
ing vehicles.
To install the towing eyelet, see “—Instal-
ling towing eyelet” on page 161.
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 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 specifically
intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing eyelet provided.

161
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.
1. Remove the towing eyelet cover on the
bumper, using a flat−bladed screwdriver
which is wrapped with a cloth.2. Use the towing eyelet in the tool bag.
Secure it to the hole on the bumper by
turning clockwise. (For the tool bag
storage location, see “—Required tools
and spare tire” on page 151.)
—Installing towing eyelet

162
3. Tighten the towing eyelet securely by
a wheel nut wrench.
CAUTION
When installing the eyelet on the ve-
hicle, be sure to tighten the eyelet
securely. If the eyelet is loose, it may
come off when being towed and re-
sult in death or serious injury.
If you cannot move the selector lever
out of “P” position to other positions
even though the brake pedal is de-
pressed, use the shift lock override but-
ton as follows:
1. Turn the ignition key to “LOCK”
position. Make sure the parking
brake is applied.
2. Pry up the cover with a flatbladed
screwdriver or equivalent.3. Insert your finger into the hole to
push down the shift lock override
button. You can move out of “P”
position only while pushing the but-
ton.
4. Shift into “N” position.
5. Insert the cover.
6. Start the engine. For your safety,
keep the brake pedal depressed.
Be sure to have the system checked by
your Scion dealer as soon as possible.

and that, on a safe incline, your vehicle
is held securely with only the parking
brake applied.
Automatic transmission “Park” mecha-
nism
Check the lock release button of the se-
lector lever for proper and smooth opera-
tion. On a safe incline, check that your
vehicle is held securely with the selector
lever in “P” position and all brakes re-
leased.
OUTSIDE THE VEHICLE
Items listed below should be performed
from time to time, unless otherwise
