1542003 MR2 from Aug. ’03 Prod. (OM17511U)
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.

Tips for driving in various
conditions

1562003 MR2 from Aug. ’03 Prod. (OM17511U)
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 nonsilicate, nonamine, nonnitrite,
and nonborate coolant with longlife hy-
brid organic acid technology.
See “Checking the engine coolant level” in
Section 72 for details of coolant type
selection.
“Toyota Super Long Life Coolant” is pre-
mixed with 50% coolant and 50% deion-
ized water. This coolant provides protec-
tion down to about 35C (31 F).
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 73 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 206 in Section 72 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—he will be pleased to
help.
Keep the door locks from freezing.
Squirt lock deicer 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.NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
03 07.07

1572003 MR2 from Aug. ’03 Prod. (OM17511U)
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
“S(1)” or “R” (sequential manual transmis-
sion) or into first or reverse (manual
transmission) and block the front wheels.
Do not use the parking brake, or snow or
water accumulated in and around the
parking brake mechanism may freeze,
making it hard to release.
Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad
winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, window scraper,
bag of sand or salt, flares, small shovel,
jumper cables, etc.
Dinghy towing
SB31003a
Your vehicle can be dinghy towed (with
four wheels on the ground) from the
front behind a motorhome.
CAUTION
Dinghy towing requires special equip-
ment and accessories. Please refer to
your service outlet of the motorhome
manufacture for the recommended
equipment.
NOTICE
Dinghy towing does not eliminate the
possibility of damage to your vehicle.
DINGHY TOWING TIPS
Before dinghy towing, be sure to ob-
serve the following in order to reduce
the damage to your vehicle.1. Shift the gear into neutral.
2. Turn the ignition switch to the “ACC” position. Make sure the audio is turned
off.
NOTICE
To avoid the locking of the steering
wheel, turn the ignition switch to the
“ACC” position.
3. Release the parking brake.
After dinghy towing, let the engine idle for
more than 3 minutes before driving the
vehicle.

SB31004a
NOTICE
Do not tow your vehicle from the
rear. This may cause serious damage
to your vehicle.
Trailer towing
SB31002
Toyota does not recommend towing a trail-
er with your MR2. It is not designed for
trailer towing.Improving fuel economy is easy—just take
it easy. It will help make your vehicle last
longer, too. Here are some specific tips
on how to save money on both fuel and
repairs:
Keep your tires inflated at the cor-
rect pressure.
Underinflation causes
tire wear and wastes fuel. See page
211 in Section 72 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
Avoid lengthy warmup idling. Once
the engine is running smoothly, begin
driving—but gently. Remember, howev-
er, that on cold winter days this may
take a little longer.
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
Avoid long engine idling. If you have
a long wait and you are not in traffic,
it is better to turn off the engine and
start again later.
Avoid engine lugging or overrev-
ving. Use a gear position suitable for
the road on which you are travelling.

How to save fuel and make
your vehicle last longer, too

1592003 MR2 from Aug. ’03 Prod. (OM17511U)
Avoid continuous speeding up and
slowing down. Stopandgo driving
wastes fuel.
Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on the clutch
or brake pedal. This causes premature
wear, overheating and poor fuel econo-
my.
Maintain a moderate speed on high-
ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on
the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corro-
sion.
Keep your vehicle tunedup and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease, brakes not adjusted, etc.
all lower engine performance and con-
tribute to poor fuel economy. For longer
life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your vehicle
receives more frequent maintenance.
(For scheduled maintenance informa-
tion, please refer to the “Scheduled
Maintenance Guide” or “Owner ’s
Manual Supplement”.)
CAUTION
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is run-
ning.

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
