CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of personal injury:
Follow jacking instructions.
 Do not put any part of your
body under the vehicle sup-
ported by the jack. Personal in-
j u ry may occu r.
 Do not start or run the engine
while your vehicle is supported
by the jack.
 Stop the vehicle on a level firm
ground, firmly set the parking
brake and put the transmission
in “R” (sequential manual
transmission) or in reverse
(manual transmission). Block
the wheel diagonally opposite
to the one being changed if
necessary.
Make sure to set the jack prop-
erly in the jack point. Raising
the vehicle with jack improper-
ly positioned will damage the
vehicle or may allow the ve-
hicle to fall off the jack and
cause personal injury.
 Never get under the vehicle
when the vehicle is supported
by the jack alone.
 Use the jack only for lifting
your vehicle during wheel
changing.
 Do not raise the vehicle with
someone in the vehicle.
 When raising the vehicle, do
not put an object on or under
the jack.
 Raise the vehicle only high
enough to remove and change
the tire.NOTICE
Do not continue driving with a
deflated tire. Driving even a
short distance can damage a
tire and wheel beyond repair.

NOTICE
If you rock your vehicle, observe the
following precautions to prevent dam-
age to the transmission and other
parts.
Do not depress the accelerator ped-
al while shifting the selector lever
or before the transmission is com-
pletely shifted to forward or reverse
gear.
 Do not race the engine and avoid
spinning the wheels.
 If your vehicle remains stuck after
rocking the vehicle several times,
consider other ways such as tow-
ing.

—From rear
(b) Using flat bed truck (a) Towing with wheel lift type truck— —From front
If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice. In consultation with them, have
your vehicle towed using either (a) or
(b).
Only when you cannot receive a towing
service from a Toyota dealer or com-
mercial tow truck service, tow your ve-
hicle carefully in accordance with the
instructions given in “—Emergency
towing” on page 179 in this Section.
Proper equipment will help ensure that
your vehicle is not damaged while being
towed. Commercial operators are generally
aware of the state/provincial and local
laws pertaining to towing.
Your vehicle can be damaged if it is
towed incorrectly. Although most operators
know the correct procedure, it is possible
to make a mistake. To avoid damage to
your vehicle, make sure the following pre-
cautions are observed. If necessary, show
this page to the tow truck driver.
TOWING PRECAUTIONS:
Use a safety chain system for all towing,
and abide by the state/provincial and local
laws. The wheels and axle on the ground
must be in good condition. If they are
damaged, use a towing dolly.
If your vehicle needs to be
towed—

1802004 MR2 from Feb. ’04 Prod. (OM17518U)
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.
—Installing towing eyelet
SB41065
1. Remove the towing eyelet cover on the bumper, using a flat −bladed screwdriver
which is wrapped with a cloth.

3. To push the link, insert a key orscrewdriver 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.

1952004 MR2 from Feb. ’04 Prod. (OM17518U)
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 normal If 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) che cks.
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.
