WARNING
■When using the compact
spare tire
●Remember that the compact
spare tire provided is specifi-
cally designed for use with your
vehicle. Do not use your com-
pact spare tire on another vehi-
cle.
●Do not use more than one com-
pact spare tires simultaneously.
●Replace the compact spare tire
with a standard tire as soon as
possible.
●Avoid sudden acceleration,
abrupt steering, sudden brak-
ing and shifting operations that
cause sudden engine braking.
■When the compact spare tire
is attached
The vehicle speed may not be
correctly detected, and the follow-
ing systems may not operate cor-
rectly:

• Tire pressure warning system
• Navigation system
■Speed limit when using the
compact spare tire
Do not drive at speeds in excess
of 50 mph (80 km/h) when a com-
pact spare tire is installed on the
vehicle.
The compact spare tire is not
designed for driving at high
speeds. Failure to observe this
precaution may lead to an acci-
dent causing death or serious
injury.
■After using the tools and jack
Before driving, make sure all the

driving with the compact spare tire
compared to when driving with
standard tires. Be careful when
driving over uneven road sur-
faces.

When trouble arises
If you have a set of jumper (or
booster) cables and a second
vehicle with a 12-volt battery,
you can jump start your vehicle
by following the steps below.
1 Vehicles with an alarm
( P.66): Confirm that the
electronic key is being car-
ried.
When connecting the jumper (or booster) cables, depending on the
situation, the alarm may activate
and doors locked. (
P. 6 7 )2 Open the hood. ( P.433)
3 Connect a positive jumper cable cl amp to on your vehicle and
connect the clamp on the other end of the positive cable to on
the second vehicle. Then, connec t a negative cable clamp to
on the second vehicle and connect the clamp at the other end of
the negative cable to .
Positive (+) battery terminal (your vehicle)
Positive (+) battery terminal (second vehicle)
Negative (-) battery terminal (second vehicle)

ond vehicle. Increase the
engine speed slightly and maintain at that level for
approximately 5 minutes to
Restarting the engine

5088-2. Steps to take in an emergency
COROLLA H/B_U
recharge the battery of your
vehicle.
5 Open and close any of the
doors of your vehicle with the
engine switch OFF.
6 Maintain the engine speed of
the second vehicle and start
the engine of your vehicle by
turning the engine switch to
ON.
7 Once the vehicle’s engine
has started, remove the
jumper cables in the exact
reverse order from which
they were connected.
Once the engine starts, have the
vehicle inspected at your Toyota
dealer as soon as possible.
■Starting the engine when the
battery is discharged
The engine cannot be started by
push-starting.
■To prevent battery discharge
●Turn off the headlights and the
audio system while the engine is
off.
●Turn off any unnecessary electri-
cal components when the vehicle
is running at a low speed for an
extended period, such as in heavy
traffic.
■When the battery is removed or
discharged
●Information stored in the ECU is
cleared. When the battery is
depleted, have the vehicle
inspected at your Toyota dealer.
●Some systems may require initial-
ization. ( P.543)
■When removing the battery ter-
minals
When the battery terminals are
removed, the information stored in
the ECU is cleared. Before remov-
ing the battery te rminals, contact
your Toyota dealer.
■Charging the battery
The electricity stored in the battery
will discharge gradually even when
the vehicle is not in use, due to nat-
ural discharge and the draining
effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the battery may discharge,
and the engine may be unable to
start. (The battery recharges auto-
matically during driving.)
■When recharging or replacing
the battery
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the bat-
tery is discharged. Use the wire-
less remote control or the
mechanical key to lock or unlock
the doors.
●The engine may not start on the
first attempt after the battery has
recharged but will start normally
after the second attempt. This is
not a malfunction.
●The engine switch mode is memo-
rized by the vehicle. When the
battery is reconnected, the system
will return to the mode it was in
before the battery was dis-
charged. Before disconnecting the
battery, turn the engine switch off.
If you are unsure what mode the
engine switch was in before the
battery discharged, be especially
careful when reconnecting the
battery.
■When replacing the battery
●Use a battery that conforms to
European regulations.
●Use a battery that the case size is
same as the previous one (LN2),
20 hour rate capacity (20HR) is

5098-2. Steps to take in an emergency
COROLLA H/B_U
8
When trouble arises
equivalent (60Ah) or greater, and
performance rating (CCA) is
equivalent (360A) or greater.
• If the sizes differ, the battery can- not be properly secured.
• If the 20 hour rate capacity is low,
even if the time period where the
vehicle is not used is a short time,
the battery may discharge and the
engine may not be able to start.
●For details, consult your Toyota
dealer.
WARNING
■When removing the battery
terminals
Always remove the negative (-)
terminal first. If the positive (+) ter-
minal contacts any metal in the
surrounding area when the posi-
tive (+) terminal is removed, a
spark may occur, le ading to a fire
in addition to electrical shocks
and death or serious injury.
■Avoiding battery fires or
explosions
Observe the following precautions
to prevent accidentally igniting the
flammable gas that may be emit-
ted from the battery:
●Make sure each jumper cable is
connected to the correct termi-
nal and that it is not unintention-
ally in contact with any other
than the intended terminal.
●Do not allow the other end of
the jumper cable connected to
the “+” terminal to come into
contact with any other parts or
metal surfaces in the area, such
as brackets or unpainted metal.
●Do not allow the + and - clamps
of the jumper cables to come
into contact with each other.
●Do not smoke, use matches,
cigarette lighters or allow open
flame near the battery.
■Battery precautions
The battery contains poisonous
and corrosive acidic electrolyte,
while related parts contain lead
and lead compounds. Observe
the following precautions when
handling the battery:
●When working with the battery,
always wear safety glasses and
take care not to allow any bat-
tery fluids (acid) to come into
contact with skin, clothing or the
vehicle body.
●Do not lean over the battery.
●In the event that battery fluid
comes into contact with the skin
or eyes, immediately wash the
affected area with water and
seek medical attention. Place a
wet sponge or cloth over the
affected area until medical
attention can be received.
●Always wash your hands after
handling the battery support,
terminals, and other bat-
tery-related parts.
●Do not allow children near the
battery.
NOTICE
■When handling jumper cables
When connecting the jumper
cables, ensure that they do not
become entangled in the cooling
fan or engine drive belt.

enced. (For example, the
vehicle speed does not
increase.)

on the multi-information dis-
play.
 Steam comes out from
under the hood.
