2006 TOYOTA AVALON key battery

’06 AVALON_U (L/O 0508)
293

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 or the steering lock func-
tion.
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 308 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.
NOTICE
 Do not race a cold engine.
 If the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.
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.

(G) A warning buzzer sounds once fromthe instrument cluster and three
times from the vehicle when a pas-
senger is getting out of the vehicle
This indicates that the passenger is at-
tempting to leave the vehicle carrying the
key, without the ignition switch is not set
at OFF. The smart key system warning
light on the instrument panel will also
come on.
When passengers get out of the vehicle,
care should be taken to leave the key
with the driver. If the driver begins driving
after a passenger gets out of the vehicle
carrying the key, a warning buzzer will
sound once more.
(H) A warning buzzer sounds from the vehicle for two seconds when lock-
ing the vehicle from the outside with
the door handle switch
This indicates that the driver is attempting
to lock the door with the key still in the
vehicle.
Leave the vehicle only after making sure
that you are carrying the key. (I) A warning buzzer sounds once from
the instrument cluster when turning
off the ignition switch
This indicates that the key battery is low.
(This warning buzzer sounds only when
the engine has been on or the ignition
switch has been set at the ON for 20
minutes or more.)
Change the key battery ahead of time in
order to ensure that the smart key system
properly.
(J) A warning buzzer sounds continu- ously from the instrument cluster
when opening the driver’s door with
the ignition switch turned off.
This indicates that the steering wheel is
not locked. Turn the engine off and then
open the door in order to lock the steering
wheel. (K) The “ENGINE START STOP” switch
flashes green once every second.
This indicates that the steering lock is
stuck. To free it, rock the steering wheel
slightly while pressing the “ENGINE
START STOP” switch.
(L) The “ENGINE START STOP” switch flashes amber once every 2 seconds.
This indicates a problem with the push
button start function or the steering lock
function. Have your vehicle checked at a
Toyota dealer.

Before making these checks, make sure
you have followed the correct starting
procedure given in “How to start the
engine” on page 290 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
309 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 311 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 308 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 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.

5. With smart key system—Charge thedischarged battery with the jumper
cables connected for approximately 5
minutes. At this time, run the engine in
the vehicle with the booster battery at
about 2000 rpm with the accelerator
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.
With smart key system—The engine may
not restart even after battery charging or
replacement. If this happens, see “(d)
Starting the engine after a battery dis-
charge”.
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.
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, it must be normalized before it
can be restarted.
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.
