When trouble arises
■Starting the engine when the battery is discharged (vehicles with Multid-
rive)
The engine cannot be started by push-starting.
■ To prevent battery discharge
●Turn off the headlights and the audio system while the engine is turned off.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic, etc.
■ 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 the battery is removed or discharged
●Vehicles with smart entry & start system: In some cases, it may not be pos-
sible to unlock the doors using the smart entry & start system when the bat-
tery is discharged. Use the wireless remote control or the mechanical key to
lock or unlock the doors.
● Vehicles with smart entry & start system: 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.
● Vehicles with smart entry & start system: 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 discharged. Before disconnect-
ing 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.
● Vehicles with Stop & Start system:
After charging the battery or reconnecting the battery terminals, the Stop &
Start system may not automatically stop the engine for approximately 5 to
40 minutes.
■ When exchanging the battery
●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.
