7-2. Steps to take in an emergency
When using a flat-bed truck to
transport the vehicle, use tire strap-
ping belts. Refer to the owner’s
manual of the flat-bed truck for the
tire strapping method.
In order to suppress vehicle move-
ment during transportation, set the
parking brake and turn the engine
switch off.
If a tow truck is not available in an
emergency, your vehicle may be
temporarily towed using cables or
chains secured to the emergency
towing eyelets. This should only be
attempted on hard surfaced roads
for at most 80 km (50 miles) at
under 30 km/h (18 mph).
A driver must be in the vehicle to
steer and operate the brakes. The
vehicle’s wheels, drivetrain, axles,
steering and brakes must be in
good condition.
For vehicles with Multidrive, only
the front towing eyelets may be
used.
To have your vehicle towed by
another vehicle, the towing eyelet
must be installed to your vehicle.
Install the towing eyelet using the
following procedure.
WARNING
■When towing the vehicle
Be sure to transport the vehicle with
the front wheels raised or with all four wheels raised off the ground. If the vehicle is towed with the front wheels
contacting the ground, the drivetrain and related parts may be damaged.

replaced, make sure to tell any autho-
rized Toyota retailer or Toyota autho- rized repairer, or any reliable repairer that the sealant is injected.
■If the tire is inflated to more than the specified air pressure
1 Press the button to let some air out.
2 Check that the air pressure indicator
shows the specified air pressure. If
the air pressure is under the desig-
nated pressure, turn the compres-
sor switch (on) again and repeat
the inflation procedure until the
specified air pressure is reached.
■The valve of a tire that has been repaired
After a tire is repaired with the emer-
gency tire puncture repair kit, the valve should be replaced.
■After a tire is repaired with the emergency tire puncture repair kit
Even if the tire inflation pressure is at the recommended level, the tire pres-sure warning light may come on/flash.
WARNING
■Do not drive the vehicle with 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.
Driving with a flat tire may cause a cir- cumferential groove on the side wall. In such a case, the tire may explode
when using a repair kit.
■When fixing the flat tire
●Stop your vehicle in a safe and flat area.
●Do not touch the wheels or the area around the brakes immediately
after the vehicle has been driven. After the vehicle has been driven, the wheels and the area around the
brakes may be extremely hot. Touching these areas with hands, feet or other body parts may result
in burns.
●Connect the valve and hose
securely with the tire installed on the vehicle. If the hose is not prop-erly connected to the valve, air
leakage may occur as sealant may be sprayed out.
●If the hose comes off the valve while inflating the tire, there is a risk that the hose will move abruptly due
to air pressure.
●After inflation of the tire has com-
pleted, the sealant may splatter when the hose is disconnected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures not
followed, the sealant may spray out.
●Keep back from the tire while it is
being repaired, as there is a chance
of it bursting while the repair opera-
tion is being performed. If you
notice any cracks or deformation of
the tire, turn (off) the compres-
sor switch and stop the repair oper-
ation immediately.
●The repair kit may overheat if oper- ated for a long period of time. Do not operate the repair kit continu-
ously for more than 40 minutes.

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.
