If the amber indicator light on the
“ENGINE START STOP” switch flashes
and the smart key system warning light
on the instrument cluster comes on,
there is a problem in the push button
start function.
Contact your Toyota dealer and have
your vehicle and all keys inspected.
In addition to the above, there are
instances in which the smart key sys-
tem does not operate properly because
of the circumstances of use. For de-
tails, see “Smart key system” on page
27 in Section 1−2.
In cases other than those described
above, it is possible that a problem has
occurred in an area other than the start
system. See “If your vehicle will not start”
on page 306 in Section 4. When the battery is disconnected or
run down,
the push button start function
memorizes the current mode. After you
reconnect, replace, or recharge the bat-
tery, the memorized mode is selected au-
tomatically. In any of these cases, turn off
the engine if the engine comes on.
Wait 10 seconds to start the engine after
the battery has been reconnected. The
engine may not start on the first try. This
does not indicate a malfunction. 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 288 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
307 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. 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 306 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 cylindertype ignition switch—
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.
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.

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 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. 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 306 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 351 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.

You can purchase a new key at your
Toyota dealer if you can give them the
key number and master key.
Vehicles with key cylinder−type ignition
switch—Even if you lose only one key,
contact your Toyota dealer at the earliest
opportunity to make a new key. If you
lose all your master keys, you cannot
make new keys; the whole engine immobi-
lizer system must be replaced.
Vehicles with smart key system—If you
lose any of your keys, contact your Toyo-
ta dealer to have new keys made. Lost
keys increase the danger of vehicle theft.
Bring all of the remaining vehicle keys
when you visit your Toyota dealer.
See the suggestion given in “Keys” on
pages 12 or 14 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.
