TIPS FOR USING SMART KEY SYSTEM
When using the smart key system, it is
possible to start or stop the engine as
long as the key is on your person.
For this reason, it is possible that a pas-
senger may remove the key from the ve-
hicle without the driver being aware of the
fact. In such a case, it is not possible to
restart the engine after having turned it
off. In addition, it is possible that one may
get out of the vehicle without being aware
that the ignition switch has not been
turned off completely.
When driving or getting in or out of the
vehicle, drivers should make sure that
they are carrying the key.
CAUTION
Do not touch the “ENGINE START
STOP” switch (engine switch) while
driving.
If you have to make an emergency stop,
press and hold the “ENGINE START
STOP” switch for more than 3 seconds.

Before making these checks, make sure
you have followed the correct starting
procedure given in “How to start the
engine” on page 296 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 pages 12 or 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” on page
315 for further instructions.
4. With smart key system—If the engine does not start even after the battery
has been recharged or replace, see
“(d) Starting the engine after a battery
discharge” on page 318 for further in-
struction. 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. Your vehicle may suddenly
move when the engine starts, and
may damage itself or cause a colli-
sion. 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. Set the ignition switch to ACC or off 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” on page 314 for further instruc-
tions.
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.
With key cylinder
−type ignition switch—If
this happens, turn the key to “START”
with the accelerator pedal fully depressed.
Keep the key and accelerator pedal in
these positions for 15 seconds and re-
lease them. Then try starting the engine
with your foot off the accelerator pedal.
With smart key system—If this happens,
press the “ENGINE START STOP” switch
(engine switch) with the brake pedal and
the accelerator pedal fully depressed, and
hold the “ENGINE START STOP” switch
for about 30 seconds. Then the cranking
hold function stops cranking automatically,
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.

NOTICE
With key cylindertype ignition
switch—Do not crank for more than
30 seconds at a time. This may over-
heat the starter and wiring systems.
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 im-
mediately. Then get immediate medi-
cal 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.
(c) Jump starting

318
With smart key system only—
In the event that the battery is dis-
charged, the engine may not restart
even after the battery is recharged or
replaced. For safety reasons, the engine
may be disabled when battery voltage
is extremely low. If the engine is dis-
abled, the start system must be normal-
ized.
To normalize the start system:1. Shift the transmission to the “P” posi- tion and set the ignition switch off.
2. Open and close any of the doors.
3. Start the engine. 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. Set the ignition switch to ACC or off, and try starting the engine again.
If the engine will not start, see “If your
vehicle will not start” on page 314 in this
Section.
CAUTION
If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual.
Vehicles with smart key system—
If the engine stalls while driving, do
not open the driver’s door until the
vehicle comes to a complete stop.
Opening the driver’s door locks the
steering wheel, resulting in loss of
steering control.
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
set the ignition switch to ACC or off.
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 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.
3. Look for obvious coolant leaks from theradiator, 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.
For the coolant type, see “Coolant type
selection” on page 358 in Section 7 −2.
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 temperature
has 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.
If your vehicle overheats
