7-2. Steps to take in an emergency
When trouble arises
Stop the vehicle in a safe place
on a hard, flat surface.
 Set the parking brake.
 Shift the shift lever to P (Multid-
rive) or N (manual transmission).
 Stop the engine.
 Turn on the emergency flashers.
( P.296)
 Check the degree of the tire
damage.
Do not remove the nail or screw
from the tire. Removing the object
may widen the opening and make
emergency repair with the repair kit
impossible.
■A flat tire that cannot be repaired with the emergency tire puncture repair kit
In the following cases, the tire cannot be repaired with the emergency tire punc-
If you have a flat tire
(vehicles with an emer-
gency tire puncture
repair kit)
Your vehicle is not equipped
with a spare tire, but instead is
equipped with an emergency
tire puncture repair kit.
A puncture caused by a nail or
screw passing through the tire
tread can be repaired tempo-
rarily using the emergency tire
puncture repair kit. (The kit
contains a bottle of sealant.
The sealant can be used only
once to temporarily repair one
tire without removing the nail
or screw from the tire.)
Depending on the damage, this
kit cannot be used to repair the
tire. ( P.313)
After temporarily repairing the
tire with the kit, have the tire
repaired or replaced by any
authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer. Repairs
conducted using the emer-
gency tire puncture repair kit
are only a temporary measure.
Have the tire repaired and
replaced as soon as possible.
WARNING
■If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the wheel beyond repair, which could
result in an accident.

7-2. Steps to take in an emergency
When trouble arises
■Starting the engine when the bat- tery 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 stopped.
●Turn off any unnecessary electrical components when the vehicle is run-ning at a low speed for an extended
period, such as in heavy traffic.
■When the battery is removed or dis- charged
●Information stored in the ECU is cleared. When the battery is depleted, have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Some systems may require initializa-tion. ( P.361)
■When removing the battery termi-
nals
When the battery terminals are removed, the information stored in the
ECU is cleared. Before removing the battery terminals, contact any autho-rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.
■Charging the battery
The electricity stored in the battery will
discharge gradually even when the vehi- cle is not in use, due to natural dis-charge and the draining effects of
certain electrical appliances. If the vehi- cle is left for a long time, the battery may discharge, and the engine may be
unable to start. (The battery recharges automatically during driving.)
■When recharging or replacing the battery
●In some cases, it may not be possible to unlock the doors using the smart
entry & start system when the battery is discharged. Use the wireless 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 mal-function.
●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 bat-tery was discharged. Before discon-
necting the battery, turn the engine switch off.If you are unsure what mode the
engine switch was in before the bat- tery discharged, be especially careful when reconnecting the battery.
●The Stop & Start system may not automatically stop the engine for up to
an hour.
■When replacing the battery
●Use a genuine battery specifically
designed for use with the Stop & Start system or a battery with equivalent specifications to a genuine battery. If
an unsupported battery is used, Stop & Start system functions may be restricted to protect the battery. Also,
battery performance may decrease and the engine may not be able to restart. Contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer for details.
●Use a battery that conforms to Euro-pean regulations.
●Use a battery that the case size is same as the previous one, 20 hour rate capacity (20HR) is equivalent or
greater, and performance rating (CCA) is equivalent or greater. Check the label on top of the battery for the
battery size and specifications (ex. LN2, 60Ah, 584A).• If the sizes differ, the battery cannot
be properly secured. • If the 20 hour rate capacity is low, even if the time period where the vehi-
cle is not used is a short time, the bat- tery may discharge and the engine may not be able to start.

engine coolant is unavailable.
6 Start the engine and turn the air
conditioning system on to check
that the radiator cooling fan
operate and to check for coolant
leaks from the radiator or hoses.
The fan operate when the air condition-
ing system is turned on immediately after a cold start. Confirm that the fan is operating by checking the fan sound
and air flow. If it is difficult to check these, turn the air conditioning system on and off repeatedly. (The fan may not
operate in freezing temperatures.)
7 If the fan is not operating: Stop
the engine immediately and
contact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
If the fan is operating: Have the
vehicle inspected at the nearest
any authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
WARNING
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under the hood, do not open the hood until the steam has subsided. The
engine compartment may be very hot.
●Keep hands and clothing (espe-cially a tie, a scarf or a muffler) away from the fan and belts. Failure
to do so may cause the hands or clothing to be caught, resulting in serious injury.
●Do not loosen the coolant reservoir caps while the engine and radiator
are hot. High temperature steam or coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
■To prevent damage to the cooling system
Observe the following precautions:
●Avoid contaminating the coolant
with foreign matter (such as sand or dust etc.).
●Do not use any coolant additive.
