check engine light TOYOTA MR2 SPYDER 2003 W30 / 3.G Owners Manual

792003 MR2 from Aug. ’03 Prod. (OM17511U)
(a) Brake System Warning Light
This light comes on in the following cases
when the ignition key is in the “ON” posi-
tion.
When the parking brake is applied...
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at your
Toyota dealer in the following case:
The light does not come on even if the
parking brake is applied when the igni-
tion key is in the “ON” position.
CAUTION
If the light does not turn off even
after the parking brake is released
while the engine is running, immedi-
ately stop your vehicle at a safe
place and contact your Toyota dealer.
In this case, the brakes may not work
properly and your stopping distance
will become longer. Depress the brake
pedal firmly and bring the vehicle to
an immediate stop.
(b) Driver’s Seat Belt Reminder Lightand Buzzer
This light and buzzer remind you to
buckle up the driver’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes and
buzzer sounds if the driver ’s seat belt is
not fastened. Unless the driver fastens the
belt, the light keeps flashing and the
buzzer stops after about 4 to 8 seconds. (c) Passenger ’s Seat Belt Reminder
Light
This light reminds you to buckle up the
passenger ’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes if a
passenger sits in the passenger seat and
does not fasten the seat belt. Unless the
passenger fastens the belt, the light stays
flashing. However, if a passenger uses an
additional seat cushion, the light may not
flash even when the seat belt is not
buckled up.
If luggage or other load is placed on the
passenger seat, depending on its weight
and how it is placed on the seat, builtin
sensors in the seat cushion may detect
the pressure, causing the reminder light to
come on.
(d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.

NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(e) Low Engine Oil Pressure WarningLight
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(f) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operation properly.
If the lamp remains on, or the lamp
comes on while driving, first check the
following.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp will not go off even after sev-
eral trips, contact your Toyota dealer as
soon as possible.
If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, elec-
tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself. Contact your Toyota dealer as soon as
possible to service the vehicle.
If the engine speed does not increase with
the accelerator pedal depressed down to
about the middle position, there may be
a problem somewhere in your electronic
throttle control system.
At this time, if you depress the accelera-
tor pedal more firmly and slowly, you can
drive your vehicle at low speeds. Have
your vehicle checked by your Toyota deal-
er 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.
Emissions lnspection and Maintenance
(I/M) programs
Your vehicle may not pass a state emis-
sion inspection if the malfunction indicator
lamp remains on. Contact your Toyota
dealer to check your vehicle’s emission
control system and OBD (OnBoard Diag-
nostics) system before taking your vehicle
for the inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” in Section 6.

ing, have your vehicle checked by your
Toyota dealer as soon as possible.
(m) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver ’s door with
the ignition key in the “ACC” or “LOCK”
position.
(n) Light reminder buzzer
The buzzer will sound if the headlight
switch is left on and the driver’s door is
opened with the key removed from the
ignition switch.
(o) Warning function of the Sequential Manual Transmission (sequential
manual transmission only)
When driving, if any incorrect operation
that may cause damage to this system is
performed or if the gear is not shifted as
desired by the driver, the warning buzzer
will sound and the gear position indicator
will flash to warn the driver in some
cases. For details, see “(k) Warning
functions” on page 94 in Section 16. CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light)
1. Apply the parking brake.
2. Open either side door. The open door warning light should
come
on.
3. Close the door. The open door warning light should go
off.
4. Turn the ignition key to “ON”, but do not start the engine.
All the service reminder indicators ex-
cept the open door warning light should
come on. The “ABS” and power steer-
ing system warning lights go off after
a few seconds. The SRS warning light
goes off after about 6 seconds.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by your Toyota
dealer as soon as possible.

If you need acceleration—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CAUTION
While driving with the cruise control
on, do not shift to the “N” position,
as this may cause engine racing or
overrevving.
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:a. Pulling the lever in the “CANCEL” direction and releasing it.
b. Depressing the brake pedal.
c. Shifting upward or downward.
If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto-
matically cancel out.
If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset
speed will also automatically cancel out. If the preset speed automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
RESETTING TO A FASTER SPEED
Push the lever up in the “RES/ACC” direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held upward, the vehicle will grad-
ually gain speed.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
lever down in the “SET/COAST” direction.
RESETTING TO A SLOWER SPEED
Push the lever down in the “SET/COAST”
direction and hold it. Release the lever
when the desired speed is attained. While
the lever is held down, the vehicle speed
will gradually decrease.
However, a faster way to reset is to de-
press the brake pedal and then push the
lever down in the “SET/COAST” direction.
RESUMING THE PRESET SPEED
If the preset speed is cancelled by pulling
the control lever, by depressing the brake
pedal, or by shifting upward or downward
the selector lever, pushing the lever up in
the “RES/ACC” direction will restore the
speed set prior to cancellation.
However, once the vehicle speed falls be-
low about 40 km/h (25 mph), the preset
speed will not be resumed.
CRUISE CONTROL FAILURE WARNING
If the “CRUISE” indicator light in the
instrument cluster flashes when using the
cruise control, press the “CRUISE ON
OFF” button to turn the system off and
then press it again to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise
control system.
The indicator light does not come on.
The indicator light flashes again.
The indicator light goes out after it
comes on.
If this is the case, contact your Toyota
dealer and have your vehicle inspected.

IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
For detailed information on oil level check,
see “Checking the engine oil level” on
page 206 in Section 72.
Iridiumtipped spark plugs
SB21011
Your engine is fitted with iridiumtipped
spark plugs.
NOTICE
Use only iridiumtipped spark plugs
and do not adjust gaps for your en-
gine performance and smooth drive-
ability.
Brake system
The tandem master cylinder brake system
is a hydraulic system with two separate
subsystems. If either subsystem should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
powerassist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserved
vacuum for one or two stops but no more!
03 07.07

1382003 MR2 from Aug. ’03 Prod. (OM17511U)
When the “ABS” warning light is on (and
the brake system warning light is off), the
antilock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
If either of the following conditions
occur, this indicates a malfunction
somewhere in the components moni-
tored by the warning light system.
Contact your Toyota dealer as soon as
possible to service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light fuming on briefly during
operation does not indicate a problem.
Brake pad wear limit indicators
SB21015
The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary. Some Toyotas are equipped with a limit-
edslip differential. If one of the rear
wheels begins to spin, the limitedslip dif-
ferential is designed to aid traction by
automatically transmitting driving force to
the other rear wheel. If you are not sure
whether your vehicle is equipped with one,
you can ask your Toyota dealer.
CAUTION
Do not start or run the engine while
your vehicle is supported by a jack.
The vehicle could be driven off the
jack and could pose a danger or re-
sult in serious injury.
NOTICE
Use only a compact spare tire of the
same size, construction and load ca-
pacity as the original tires on your
Toyota because damage to the limit-
edslip differential could possibly oc-
cur with another tire type.

Before starting the engine
1. Check the area around the vehicle be-fore entering it.
Sequential manual transmission only:
When the driver ’s door is opened, a motor
sound may be heard from the engine
compartment, but it is not a malfunction.
The motor will stop after a certain period
of time. 2. Adjust seat position, seatback angle, seat cushion angle and steering wheel
angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock both the doors.
5. Fasten seat belts. 1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces-
sories.
3. Sequential manual transmission: Turn
the ignition switch to “ON” position.
Hold down the brake pedal firmly, and
place the selector lever to the “N” posi-
tion. Make sure that the “N” indicator
in the instrument cluster comes on. A
starter safety device will prevent the
starter from operating if the selector
lever is in a position except “N” or the
brake pedal is not depressed.
Manual transmission: Press the clutch
pedal to the floor and shift the trans-
mission into neutral. Hold the clutch
pedal to the floor until the engine is
started. A starter safety device will pre-
vent the starter from operating if the
clutch pedal is not fully depressed.
(b) Starting the engine
Before starting the engine, be sure to
follow the instructions in “(a) Before
cranking”.
Normal starting procedure
The multiport fuel injection system/sequen-
tial multiport fuel injection system in your
engine automatically controls the proper
airfuel mixture for starting. You can start
a cold or hot engine as follows:
Sequential manual transmission: With
your foot off the accelerator pedal, turn
the ignition key to the ”START” position
and crank the engine while depressing
the brake pedal. Release the key when
the engine starts.
The engine cannot be cranked if the
selector lever is in a position except
”N” or the brake pedal is not de-
pressed.
Manual transmission: With your foot
off the accelerator pedal, crank the en-
gine by turning the key to the “START”
position. Release the key when the en-
gine starts.
Engine should be warmed up by driving,
not in idle. For warming up drive with
smoothly turning engine until engine cool-
ant temperature is within normal range.

How to start the engine—
(a) Before cranking

1552003 MR2 from Aug. ’03 Prod. (OM17511U)
If the engine stalls...
Simply restart it, using the correct proce-
dure given in normal starting.
If the engine will not start...
See “If your vehicle will not start—” on
page 162 in Section 4.
NOTICE
Do not crank for more than 30 sec-
onds at a time. This may overheat
the starter and wiring systems.
 Do not race a cold engine.
 If the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.
Always slow down in gusty crosswinds.
This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharpedged objects and
other road hazards. Failure to do so
can lead to severe tire damage such
as a tire burst.
Drive slowly when passing over bumps
or travelling on a bumpy r oad. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in “S(1)” or “R” (sequential manual
transmission) or in first or reverse
(manual transmission). If necessary,
block the wheels.
Washing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.
CAUTION
Before driving off, make sure that
the parking brake is fully released
and the parking brake reminder
light is off.
Do not leave your vehicle unat-
tended while the engine is running.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.
Be careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking could cause
the vehicle to spin or skid.

Before making these checks, make sure
you have followed the correct starting
procedure given in “How to start the
engine” on page 154 in Section 3 and that
you have sufficient fuel. Also check
whether the other keys will start the
engine. If they work, your key may be
broken. Have the key checked at your
Toyota dealer. If none of your keys work,
there may be a malfunction in the immobi-
lizer system. Call your Toyota dealer. (See
“Keys” on page 8 in Section 12.)
If the engine is not turning over or is
turning over too slowly—1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked, the battery
is discharged. You may try jump start-
ing. See “(c) Jump starting” on page
163 for further instructions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call a Toyota dealer or qualified repair
shop.NOTICE
 Sequential manual transmission
only: Your vehicle cannot be pull
or pushstarted.
 Do not pull or pushstart the ve-
hicle. It may damage the vehicle or
cause a collision when the engine
starts. Also the threeway catalytic
converter may overheat and become
a fire hazard.
If the engine turns over at its normal
speed but will not start—
1. The engine may be flooded because of repeated cranking. See “(b) Starting a
flooded engine” on page 162 for further
instructions.
2. If the engine still will not start, it needs adjustment or repair. Call a Toyota
dealer or qualified repair shop.
(b) Starting a flooded engine
If the engine will not start, your engine
may be flooded because of repeated
cranking.
Sequential manual transmission: If this
happens, turn the key to “START” with the
accelerator pedal and brake pedal fully
depressed. Keep the key, accelerator ped-
al and brake pedal in these positions for
15 seconds and release them. Then re-
lease the accelerator pedal, and try crank-
ing the engine with the brake pedal de-
pressed.
Manual transmission: If this happens,
turn the key to “START” with the accelera-
tor pedal fully depressed. Keep the key
and accelerator pedal in these positions
for 15 seconds and release them. Then
try starting the engine with your foot off
the accelerator pedal.
If the engine does not start after 15 sec-
onds of cranking, release the key, wait a
few minutes and try again.
