Raise the tire.
To protect the wheel design faces,
place rags between the wheel
design faces and the frame.
While raising, secure the tire, tak-
ing care that the tire goes straight

rounding part, to prevent it from fly-
ing forward during a collision or
sudden braking.
After the tire goes half way up,
check that the suspended chain is
able to enter the tire hole, for
proper storage.

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 any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer
as soon as possible.
■ Starting the engine when the battery is discharged (vehicles with auto-
matic transmission)
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.
(Vehicles with Stop & Start system: Except when the engine is stopped due
to the Stop & Start system)
● Turn off any unnecessary electrical 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 any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
● The power windows may not close normally. In this case, initialize the power
windows. (if equipped) ( P. 185)
● If it is necessary to initialize the panoramic view monitor (if equipped), refer
to “Navigation and multimedia system Owner’s manual” or “Multimedia
Owner’s Manual”.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle 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 trouble arises
■When recharging or replacing the battery (vehicles with smart entry &
start system)
● 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 malfunction.
● The engine switch mode is memorized by the vehicle. When the battery is
reconnected, the system will return to the mode it was in before the battery
was discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
● Vehicles with Stop & Start system: After the battery terminals have been dis-
connected and reconnected or, the battery has been replaced, the Stop &
Start system may not automatically stop the engine for up to an hour.
■ When replacing the battery
● Use a battery that conforms to European regulations.
● Use a battery with the same case size as the previous battery and an equiv-
alent 20 hour rate capacity (20HR) or greater.
• 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 battery may discharge and the engine
may not be able to start.
● Vehicles with Stop & Start system: 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.
● For details, consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
