2005 TOYOTA MR2 SPYDER check engine

1662005 MR2 from Aug. ’04Prod. (OM17527U)
If your engine stalls while driving...
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3.Sequential manual transmission: Turn
the ignition key to “ACC” or “LOCK”
position. Approximately 5 seconds after,
try starting the engine again.
Manual transmission: Turn the ignition
key to “ACC” or “LOCK”, and try start-
ing the engine again.
If the engine will not start, see “If your
vehicle will not start—” on page 162 in
this Section.
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.
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to ”ACC” or
”LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
If your vehicle overheats
If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure...
1. Pull safely off the road, stop the ve-
hicle and turn on your emergency
flashers. Put the transmission in “N”
(sequential manual transmission) or in
neutral (manual transmission) and ap-
ply the parking brake. Turn off the air
conditioning if it is being used.
2. If coolant or steam is boiling out of the
radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine
running and make sure the electric
cooling fan is operating. If it is not,
turn the ignition off.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.

drivingIf you cannot increase engine
speed

3. Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the coolant is leaking, stop the en-
gine immediately. Call a Toyota dealer
for assistance.
5. If there are no obvious leaks, check
the coolant reservoir. If it is dry, add
coolant to the reservoir while the en-
gine is running. Fill it about half full.
CAUTION
Do not attempt to remove the coolant
reservoir cap or air release valve
when the engine and radiator are hot.
Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
6. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You should have it checked as
soon as possible at your Toyota dealer.
If you have a flat tire—
1. Reduce your speed gradually,
keeping a straight line. Move cau-
tiously off the road to a safe place
well away from the traffic. Avoid
stopping on the center divider of
a highway. Park on a level spot
with firm ground.
2. Stop the engine and turn on your
emergency flashers.
3. Firmly engage the parking brake
and put the transmission lever in
“R” (sequential manual transmis-
sion) or in reverse (manual trans-
mission).
4. Have everyone get out of the ve-
hicle on the side away from traffic.
5. Read the following instructions
thoroughly.

3. To push the link, insert a key or
screwdriver to the hole. The lever
can be operated while the link is
being pushed.
4. Shift into the ”N” position.
5. Reinsert the cover.
6. Start the engine while depressing the
brake pedal.
Be sure to have the system checked by
your Toyota dealer as soon as possible.
If you lose your keys
You can purchase a new key at your
Toyota dealer if you can give them the
key number and master key.
Even if you lose only one key, contact
your Toyota dealer to make a new key. If
you lose all your master keys, you cannot
make new keys; the whole engine immobi-
lizer system must be replaced.
See the suggestion given in “Keys” on
page 8 in Section 1−2.
If your keys are locked in the vehicle and
you cannot get a duplicate, many Toyota
dealers can still open the door for you,
using their special tools. If you must
break a window to get in, we suggest
breaking the side window because it is
the least expensive to replace. Be ex-
tremely cautious to avoid cuts from the
glass.

1952005 MR2 from Aug. ’04Prod. (OM17527U)
Be on the alert for changes in perfor-
mance, sounds, and visual tip−offs that
indicate service is needed. Some impor-
tant clues are as follows:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)
Flat−looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving
straight on a level road
Strange noises related to suspension
movement
Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
Engine coolant temperature continually
higher than normalIf you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.
Some states have vehicle emission in-
spection programs which include OBD
(On−Board Diagnostics) checks.
The OBD system monitors the operation
of the emission control system. When the
OBD system determines that a problem
exists somewhere in the emission control
system, the malfunction indicator lamp
comes on. In this case, your vehicle may
not pass the I/M test and need to be
repaired. Contact your Toyota dealer to
service the vehicle.
Even if the malfunction indicator lamp
does not come on, your vehicle may not
pass the I/M test as readiness codes
have not been set in the OBD system.
Readiness codes are automatically set
during ordinary driving. However, when the
battery is disconnected or run down, the
codes are erased. Also, depending on
your driving habits, the codes may not be
completely set.
Also, if the malfunction indicator lamp had
come on recently due to temporary mal-
function such as a loose fuel tank cap,
your vehicle may not pass the I/M test.

Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
Be careful not to scratch the glass
surface with the wiper frame.
When closing the engine hood or
trunk, check to see that you have
not forgotten any tools, rags, etc.
