STARTING AND DRIVING211
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
air−fuel mixture for starting. You can start
a cold or hot engine as follows:
Multi−mode manual transmission:With
your foot off the accelerator pedal, turn
the engine switch to the “START” posi-
tion and crank the engine while depress-
ing the brake pedal. Release the key
when the engine starts. The engine can-
not be cranked if the shift lever is in a
position except “N” or the brake pedal
is not depressed.
Manual transmission:With your foot off
the accelerator pedal, crank the engine
by turning the engine switch to the
“START” position. Release it when the
engine starts.
Engine should be warmed up by driving,
not idling. For warming up drive with a
smoothly turning engine until the engine
coolant temperature is within the normal
range.
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
220 in Section 4.
NOTICE
zDo not crank for more than 30 se-
conds at a time. This may overheat
the starter and wiring systems.
zDo not race a cold engine.
zIf the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.
Pre−trip safety check
It is a good idea to do a safety check
before starting out on a trip. A few min-
utes of checking can help ensure safe and
pleasant driving. Just a basic familiarity
with your vehicle is required and a careful
eye! Or, if you would like, any authorized
Toyota dealer or repairer, or another duly
qualified and equipped professional, will
be pleased to make this check for you at
nominal cost.
CAUTION
If you make this check in an enclosed
garage, make sure there is adequate
ventilation. Engine exhaust is poison-
ous.
BEFORE STARTING THE ENGINE
Outside the vehicle
Tires.Check the pressure with a gauge
and look carefully for cuts, damage, or
excessive wear.
Wheel bolts.Make sure no bolts are mis-
sing or loose.
Fluid leaks.After the vehicle has been
parked for a while, check underneath for
leaking fuel, oil, water, or fluid. (Water
dripping from the air conditioning after use
is normal.)
Lights.Make sure the headlights, stop
lights, tail lights, turn signals and other
lights are all working. Check the headlight
aim.
Inside the vehicle
Spare tire, jack and wheel bolt wrench.
Check the spare tire pressure and make
sure you have your jack and wheel bolt
wrench.

4. Loosen all the wheel bolts.
Always loosen the wheel bolts before rais-
ing the vehicle.
Turn the wheel bolts counterclockwise to
loosen. To get maximum leverage, fit the
wrench to the bolt 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 handle. Be careful that
the wrench does not slip off the bolt.
Do not remove the bolts yet—just unscrew
them about one−half turn.
CAUTION
Never use oil or grease on the bolts.
The bolts may loosen and the wheels
may fall off, which could cause a se-
rious accident.

6. After making sure that no one is in
the vehicle, raise it high enough so
that the spare tire can be installed.
Remember you will need more ground
clearance when putting on the spare tire
than when removing the flat tire.
To raise the vehicle, turn the jack handle
clockwise. As the jack touches the vehicle
and begins to lift, double−check that it is
properly positioned.
CAUTION
Never get under the vehicle when the
vehicle is supported by the jack
alone.

7. Remove the wheel bolts and change
tires.
Lift the flat tire straight off and put it
aside.
Roll the spare wheel into position and
align the vehicle side holes with the tire
wheel holes. Then secure the wheel with
the bolts.

MS41016a
Before putting on wheels, remove any cor-
rosion on the mounting surfaces with a
wire brush or such. Installation of wheels
without good metal−to−metal contact at the
mounting surface can cause wheel bolts to
loosen and eventually cause a wheel to
come off while driving.
—Reinstalling wheel bolts
MS41017a
8. Reinstall all the wheel bolts finger
tight.
Reinstall the wheel bolts and tighten them
as much as you can by hand. Press back
on the tire and see if you can tighten
them more.
CAUTION
Never use oil or grease on the bolts.
Doing so may lead to overtightening
the bolts and damaging the bolts. The
bolts may loosen and the wheels may
fall off, which could cause a serious
accident. If there is oil or grease on
any bolt, clean it.

IN CASE OF AN EMERGENCY233
—Lowering your vehicle
MS41018b
9. Lower the vehicle completely and
tighten the wheel bolts.
Turn the jack handle counterclockwise to
lower the vehicle.
Use only the wheel bolt wrench and turn
it clockwise to tighten the bolts. Do not
use other tools or any additional leverage
other than your hands, such as a hammer,
pipe or your foot. Make sure the wrench
is securely engaged over the bolt.
Tighten each bolt a little at a time in the
order shown. Repeat the process until all
the bolts are tight.
CAUTION
DWhen lowering the vehicle, make
sure that all portions of your body
and all other persons around will
not be injured as the vehicle is low-
ered to the ground.
DHave the wheel bolts tightened with
torque wrench to 103 N·m (10.5
kgf·m, 76 ft·lbf), as soon as pos-
sible after changing wheels. Other-
wise, the bolts may loosen and the
wheels may fall off, which could
cause a serious accident.
DTightening the bolts too much could
cause wheel deformation or cracks,
and may result in serious accidents.
DDo not attach a heavily damaged
plastic wheel ornament. It may fly
off the wheel and cause accidents
while the vehicle is moving.

IN CASE OF AN EMERGENCY235
—After changing wheels
11. Check the air pressure of the re-
placed tire.
Adjust the air pressure to the specifica-
tions designated on page 299 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.
12. Restow all the tools, jack and flat
tire securely.
As soon as possible after changing
wheels, tighten the wheel bolts to the
torque specified on page 299 in Section
8 with a torque wrench. Have a technician
repair the flat tire and replace the spare
tire with it.
CAUTION
Before driving, make sure all the
tools, jack and flat tire are securely
placed in their storage locations to
reduce the possibility of death or se-
rious injury during sudden braking,
sudden swerving or an accident.
PS41515
Aluminium wheels:
Before stowing the flat tire, remove the
center wheel ornament by pushing from
the reverse side.
Be careful not to lose the wheel ornament.

DO−IT−YOURSELF MAINTENANCE: Engine and Chassis275
Replacing wheels
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace a damaged wheel,
the tire may slip off the wheel or cause
loss of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and inset
∗.
Correct replacement wheels are available
at your Toyota dealer or repairer, or
another duly qualified and equipped pro-
fessional.
∗: Conventionally referred to as “offset”.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis.
Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
CAUTION
Do not use wheels other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control. Otherwise, an accident may
occur resulting in death or serious
injuries.
Aluminum wheel precautions
DWhen installing aluminum wheels,
check that the wheel bolts are tight
after driving your vehicle the first1600
km (1000 miles).
DIf you have rotated, repaired, or
changed your tires, check that the
wheel bolts are still tight after driving
1600 km (1000 miles).
DWhen using tire chains, be careful not
to damage the aluminum wheels.
DToyota recommends the use of Toyota
genuine wheel bolts and wrench de-
signed for your aluminum wheels. Oth-
er bolts and wrenches of matching
quality can also be used.
DWhen balancing your wheels, Toyota
recommends the use of Toyota genuine
balance weights. Other balance weights
canalsobeused.
DAs with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.
