Before making these checks, make sure
you have followed the correct starting pro-
cedure given in “How to start the engine”
on page 370 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 immobilizer system. Call
your Toyota dealer. (See “Keys” on page
14 in Section 1−2.)
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” 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
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. Turn the ignition key to “ACC” or “LOCK” and try starting the engine
again.
2. If the engine will not start, the engine may be flooded because of repeated
cranking. See “(b) Starting a flooded
engine” for further instructions.
3. If the engine still will not start, it needs adjustment or repair. Call a Toyota
dealer or qualified repair shop. If the engine will not start, your engine
may be flooded because of repeated
cranking.
If this happens, turn the ignition key to
“START” with the accelerator pedal fully
depressed, and hold the key at this posi-
tion for about 30 seconds. Then the
cranking hold function stops cranking au-
tomatically, and you can try starting the
engine with your foot off the accelerator
pedal.
If the engine does not start, wait a few
minutes and try again.
If the engine still will not start, it needs
adjustment or repair. Call a Toyota dealer
or qualified repair shop for assistance.

To avoid serious personal injury and
damage to your vehicle which might re-
sult from battery explosion, acid burns,
electrical burns, or damaged electronic
components, these instructions must be
followed precisely.
If you are unsure about how to follow this
procedure, we strongly recommend that
you seek the help of a competent me-
chanic or towing service.
CAUTION
Batteries contain sulfuric acid
which is poisonous and corrosive.
Wear protective safety glasses when
jump starting, and avoid spilling
acid on your skin, clothing, or ve-
hicle.
If you should accidentally get acid
on yourself or in your eyes, remove
any contaminated clothing and flush
the affected area with water imme-
diately. Then get immediate medical
attention. If possible, continue to
apply water with a sponge or cloth
while en route to the medical office.
The gas normally produced by a
battery will explode if a flame or
spark is brought near. Use only
standardized jumper cables and do
not smoke or light a match while
jump starting.
NOTICE
The battery used for boosting must
be 12 V. Do not jump start unless you
are sure that the booster battery is
correct.
JUMP STARTING PROCEDURE1. If the booster battery is installed in another vehicle, make sure the vehicles
are not touching. Turn off all unneces-
sary lights and accessories.
When boosting, use the battery of
matching or higher quality. Any other
battery may be difficult to jump start
with.
If jump starting is difficult, charge the
battery for several minutes.
2. If required, remove all the vent plugs from the booster and discharged batter-
ies. Lay a cloth over the open vents
on the batteries. (This helps reduce the
explosion hazard, personal injuries and
burns.)
3. If the engine in the vehicle with the booster battery is not running, start it
and let it run for a few minutes. During
jump starting run the engine at about
2000 rpm with the accelerator pedal
lightly depressed.

jumper cables or clamps touch any-
thing except the correct battery termi-
nals or the ground.

5. Charge the discharged battery with thejumper cables connected for approxi-
mately 5 minutes. At this time, run the
engine in the vehicle with the booster
battery at about 2000 rpm with the ac-
celerator pedal lightly depressed.
6. Start your engine in the normal way. After starting, run it at about 2000 rpm
for several minutes with the accelerator
pedal lightly depressed.
7. Carefully disconnect the cables in the exact reverse order: the negative cable
and then the positive cable.
8. Carefully dispose of the battery cover cloths—they may now contain sulfuric
acid.
9. 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 the first start attempt is not success-
ful...
Check that the clamp on the jumper
cables are tight. Recharge the discharged
battery with the jumper cables connected
for several minutes and restart your en-
gine in the normal way.
If the another attempt is not successful,
the battery may be depleted. Have it ch-
ecked at any authorized Toyota dealer or
repairer, or another duly qualified and
equipped professional.
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 390 in this
Section.
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 stalls while
driving

If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer 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.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
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.
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.
3. Visually check to see if the enginedrive belt (fan belt) is broken or loose.
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 engine drive belt is broken or thecoolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as-
sistance.
5. If the engine drive belt is O.K. and there are no obvious leaks, you may
help the engine cool down more quickly
by running it at about 1500 rpm for a
few minutes with the accelerator pedal
lightly depressed.
6. Check the coolant reservoir. If it is dry, add coolant to the reservoir while the
engine is running. Fill it about half full.
For the coolant type, see “Coolant type
selection” on page 434 in Section 7 −2.
If you cannot incr ease engine
speed If your vehicle overheats

3952007 SEQUOIA from Aug. ’07 Prod. (OM34462U)
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.
7. 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 cau-
tiously 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 ve- hicle on the side away from traffic.
5. Read the following instructions thoroughly.CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of death or serious injury:
Follow jacking instructions.
 Do not put any part of your
body under the vehicle sup-
ported by the jack. Otherwise,
personal injury may occur.
 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 “P”. Block the wheel diago-
nally opposite to the one being
changed if necessary.
If you have a flat tire—

3962007 SEQUOIA from Aug. ’07 Prod. (OM34462U)
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 place any objects on top
of or underneath 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.
 Vehicles with rear height con-
trol air suspension system:
When jacking up or insta lling
tire chains, be sure to set
manual control mode by
pushing the height control
mode select switch and stop
the engine. Otherwise, the
vehicle height may change
because of the automatic lev-
eling function, resulting in an
accident.
