ECU TOYOTA MR2 SPYDER 2005 W30 / 3.G Owner's Manual

1562005 MR2 from Aug. ’04Prod. (OM17527U)
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has highspeed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are highspeed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a lon-
ger stopping distance, and it may
pull to one side when the brakes
are applied. Also, the parking brake
will not hold the vehicle securely.
Winter driving tips
Make sure your coolant is properly pro-
tected against freezing.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
and non−borate coolant with long−life hy-
brid organic acid technology. (Coolant with
long−life hybrid organic acid technology is
a combination of low phosphates and or-
ganic acids.)
See “Checking the engine coolant level” in
Section 7−2 for details of coolant type
selection.
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about −35C (−31F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and
cables.Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Section 7−3 tells you how to visually
inspect the battery. Your Toyota dealer
and most service stations will be pleased
to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 208 in Section 7−2 for recom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may cause harder starting. If you
are not sure about which oil to use, call
your Toyota dealer—they will be pleased
to help.
Keep the door locks from freezing.
Squirt lock de−icer or glycerine into the
locks to keep them from freezing.
Use a washer fluid containing an anti-
freeze solution.
This product is available at your Toyota
dealer and most auto parts stores. Follow
the manufacturer ’s directions for how
much to mix with water.

3. Loosen the bolt and remove it.
Then take the spare tire out of the
vehicle.
When storing the spare tire, put it in
place with the outer side of the wheel
facing up. Then secure the tire by re-
peating the above removal steps in
reverse order to prevent it from flying
forward during a collision or sudden
braking.
—Blocking the wheel
SB41035
2. Block the wheel diagonally op-
posite the flat tire to keep the
vehicle from rolling when it is
jacked up.
When blocking the wheel, place a
wheel block in front of one of the front
wheels or behind one of the rear
wheels.
—Loosening wheel nuts
SB41027a
3. Loosen all the wheel nuts.
Always loosen the wheel nuts before
raising the vehicle.
Turn the wheel nuts counterclockwise
to loosen. To get maximum leverage,
fit the wrench to the nut so that the
handle is on the right side, as shown
above. Grab the wrench near the end
of the handle and pull up on the han-
dle. Be careful that the wrench does
not slip off the nut.
Do not remove the nuts yet—just un-
screw them about one−half turn.

—Reinstalling wheel nuts
SD04004b
7. Reinstall all the wheel nuts with
finger tight.
Reinstall the wheel nuts (tapered end
inward) and tighten them as much as
you can by finger. Press back on the
tire back and see if you can tighten
them more.
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
SB41031b
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 and
turn it clockwise to tighten the nuts.
Do not use other tools or any addition-
al leverage other than your hands,
such as a hammer, pipe or your foot.
Make sure the wrench is securely en-
gaged over the nut.
Tighten each nut a little at a time in
the order shown. Repeat the process
until all the nuts are tight.

1752005 MR2 from Aug. ’04Prod. (OM17527U)
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 designated on page 244 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 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.
As soon as possible after changing
wheels, tighten the wheel nuts to the
torque specified on page 244 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire and re-
place the spare tire with it.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.

—Emergency towing
SB41033c
Front
SB41034b
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 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 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 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.

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 169 in this
Section.)
SB41067
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.

1. Turn the ignition key to the ”LOCK”
or “ACC” position. Make sure the
parking brake is applied.
2. Pry up the cover with a flatbladed
screwdriver or equivalent.

If you notice any change in the sound of
the exhaust or smell exhaust fumes, have
the cause located and corrected immedi-
ately. (See “Engine exhaust cautions” on
page 133 in Section 2.)
INSIDE THE VEHICLE
Items listed below should be checked
regularly, e.g. while performing periodic
services, cleaning the vehicle, etc.

been parked for a while. If you smell fuel
fumes or notice any leak, have the cause
found and corrected immediately.
Doors and trunk lid
Check that both the doors operate
smoothly and all latches lock securely.
Make sure the trunk lid secondary latch
secures the lid from opening when the
primary latch is released.
Tire pressure
Check the pressure with a gauge ev-
ery two weeks, or at least once a
month. See page 213 in Section 7−2
for additional information.
Tire surface and wheel nuts
Check the tires carefully for cuts,
damage or excessive wear. See page
