Connecting point for 5.7 L V8 (3URFE)
engine
Do not connect the cable 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. Charge the discharged battery with the
jumper 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 another attempt is not successful, the
battery may be depleted. 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 engine switch to the “ACC” or “LOCK” position, and try starting the
engine again.
If the engine will not start, see “If your
vehicle will not start” on page 498 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 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 engine switch is turned to the “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.
If your engine stalls while
driving If you cannot incr
ease engine
speed If your vehicle overheats

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.
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 death or serious 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.

If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice.
If towing service is not available in an
emergency, your vehicle may be tempo-
rarily towed by a cable or chain se-
cured to one of the emergency towing
eyelet under the front of the vehicle.
Use extreme caution when towing the
vehicle.
NOTICE
Only use specified towing eyelet;
otherwise your vehicle may be dam-
aged.
A driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done only
on hard−surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, drive train, steering and
brakes must all be in good condition.
CAUTION
Use extreme caution when towing the
vehicle. Avoid sudden starts or errat-
ic driving maneuvers which would
place excessive stress on the emer-
gency towing eyelet and towing cable
or chain. The eyelet and towing cable
or chain may break and cause serious
injury or damage.
NOTICE
Use only a cable or chain specifically
intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing eyelet provided.
Before towing, release the parking brake
and put the transmission in “N”. The
engine switch must be in the “ACC”
(engine off) or “ON” (engine running)
position.
Four −wheel drive models—Put the front
drive control switch knob in “2WD”.
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.

3. Insert the screwdriver or equivalent
into the hole to push down the shift
lock override button. You can shift
out of “P” position only while push-
ing the button.
4. Shift into “N” position.
5. Insert the cover.
6. Start the engine. For your safety, keep the brake pedal depressed.
Be sure to have the system checked by
your Toyota dealer as soon as possible. You can purchase a new key at your
Toyota dealer if you can give them the
key number. If your vehicle is equipped
with the engine immobilizer system, the
dealer will also need your master key.
Vehicles with engine immobilizer sys-
tem—Even if you lose only one key, con-
tact your Toyota dealer to make a new
key. If you lose all your master keys, you
cannot make new keys; the whole engine
immobilizer system must be replaced.
See the suggestion given in “Keys” on
page 18 in Section 1
−2.
If your keys are locked in the vehicle and
you cannot get a duplicate, many Toyota
dealers can still open the door for you,
using their special tools. If you must
break a window to get in, we suggest
breaking the smallest side window be-
cause it is the least expensive to replace.
Be extremely cautious to avoid cuts from
the glass. You can purchase a new wireless re-
mote control transmitter at your Toyota
dealer.
Have the registered identification numbers
of your transmitters deleted from your ve-
hicle by your Toyota dealer as soon as
possible to avoid the possibility of theft or
an accident. Then, have the identification
number of your new transmitter registered.
At the same time, you must bring all of
the remaining transmitters to have them
registered again as well.
You can use the wireless remote control
system with the new transmitter. Contact
your Toyota dealer for detailed information.

For the engine oil capacity, see “Service
specifications” on page 589 in Section 8.
When the level reaches within the correct
range, install the filler cap hand−tight.
NOTICE
 Be careful not to spill engine oil on
the vehicle components.
 Avoid overfilling, or the engine
could be damaged.
 Check the oil level on the dipstick
once again after adding the oil.
