Do not connect it to or near any part
that moves when the engine is
cranked.
CAUTION
When making the connections, to
avoid serious injury, do not lean over
the battery or accidentally let the
jumper cables or clamps touch any-
thing except the correct battery termi-
nals or the ground.
5. Start your engine in the normal way.
After starting, run it at about 2000 rpm
for several minutes with the accelerator
pedal lightly depressed.
6. Carefully disconnect the cables in the exact reverse order: the negative cable
and then the positive cable.
7. Carefully dispose of the battery cover cloths—they may now contain sulfuric
acid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is
not apparent (for example, lights left on),
you should have it checked at your Toyota
dealer. 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. Turn the ignition key to “ACC” or “LOCK”, and try starting the engine
again.
If the engine will not start, see “If your
vehicle will not start” on page 216.
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 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 “P”
and apply 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.

driving If your vehicle overheats

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 radiator
cap 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 temperaturehas 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 s hould have it checked as
soon as possible at your Toyota dealer. 1. Reduce your speed gradually, keeping
a straight line. Move cautiously 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 set the parking brake and put the transmission in “P”.
4. Have everyone get out of the vehicle on the side away from traffic.
5. Read the following instructions thor- oughly.
CAUTION
When jacking, be sure to observe the
following to reduce the possibility of
personal injury:
Follow jacking instructions.
Do not put any part of your body
under the vehicle supported by the
jack. Otherwise, personal injury may
occur.
Do not start or run the engine while
your vehicle is supported by the
jack.
If you have a flat tire—

2212003 HIGHLANDER from Aug. ’02 Prod. (OM48441U)
Stop the vehicle on a level firm
ground, firmly set the parking brake
and put the transmission in “P”.
Block the wheel diagonally opposite
to the one being changed if neces-
sary.
Make sure to set the jack properly
in the jack point. Raising the ve-
hicle with jack improperly posi-
tioned will damage the vehicle or
may allow the vehicle 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 some-
one in the vehicle.
When raising the vehicle, do not
place any objects on top of or un-
derneath the jack.
Raise the vehicle only high enough
to remove and change the tire.
NOTICE
Do not continue driving with a de-
flated tire. Driving even a short dis-
tance can damage a tire and wheel
beyond repair.
1. Get the required tools and spare
tire.
1. Jack handle
2. Wheel nut wrench
3. Front towing eyelet
4. Jack
5. Spare tire
To prepare yourself for an emergency, you
should fam iliarize yourself with the use of
the jack, each of the tools and their stor-
age locations.

Turn the jack joint by hand.
To remove: Turn the joint in direction 1
until the jack is free.
To store: Turn the joint in direction 2 until
the jack is firmly secured to prevent it
flying forward during a collision or s udden
braking.To remove the spare tire:
1. Hang the deck board on the weather- strip.
2. Remove the spare tire cover.
3. Loosen the bolt and remove it.2. Block the wheel diagonally opposite the flat tire to keep the vehicle from
rolling when it is j acked up.
When blocking the wheel, place a wheel
block in front of one of the front wheels
or behind one of the rear wheels.

3. Remove the wheel ornament.
Pry off the wheel ornament, using the
beveled end of the wheel nut wrench as
shown.
CAUTION
Do not try to pull off the ornament by
hand. Take due care in handling the
ornament to avoid unexpected person-
al injury.
4. Loosen all the wheel nuts.
Always loosen the wheel nuts before rais-
ing the vehicle.
Turn the wheel nuts counterclockwise to
loosen. To get maximum leverage, fit the
wrench to the nut 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 nut.
Do not remove the nuts yet—just unscrew
them about onehalf turn.

CAUTION
Never use oil or grease on the bolts
or nuts. The nuts may loose and the
wheels may fall off, which could cau-
se a serious accident.
5. Position the jack at the correct jack
point as shown.
Make sure the jack is positioned on a
level and solid place.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, insert the jack handle
into the jack (it is a loose fit) and turn it
clockwise. As the jack touches the vehicle
and begins to lift, doublecheck that it is
properly positioned.

CAUTION
Never get under the vehicle when the
vehicle is supported by the jack
alone.
7. Remove the wheel nuts and change
tires.
Lift the flat tire straight off and put it
aside.
Roll the spare wheel into position and
align the holes in the wheel with the bolts.
Then lift up the wheel and get at least the
top bolt started through its hole. Wiggle
the tire and press it back over the other
bolts.Before putting on wheels, remove any cor-
rosion on the mounting surfaces with a
wire brush or such. Installation of wheels
without good metaltometal contact at the
mounting surface can cause wheel nuts to
loosen and eventually cause a wheel to
come off while driving.

8. Reinstall all the wheel nuts finger
tight.
Reinstall the wheel nuts (tapered end in-
ward) and tighten them as much as you
can by hand. Press back on the tire back
and see if you can tighten them more.
CAUTION
Never use oil or grease on the bolts
or nuts. Doing so may lead to over-
tightening the nuts and damaging the
bolts. The nuts may loose and the
wheels may fall off, which could cau-
se a serious accident. If there is oil
or grease on any bolt or nut, clean
it.
9. Lower the vehicle completely and tighten the wheel nuts.
Turn the jack handle counterclockwise to
lower the vehicle.
Use only the wheel nut wrench and turn
it clockwise to tighten the nuts. 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 nut.
Tighten each nut a little at a time in the
order shown. Repeat the process until all
the nuts are tight. (For the tightening
torque, see “Tires” on page 289 in Section
8.)
