5-2. Steps to take in an emergency
SIENNA_U (OM45477U)
■
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 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 discharged
● The power sliding door (if equipped) must be initialized. ( P. 67)
● The power back door (if equipped) must be initialized. ( P. 82)
● The moon roof (if equipped) must be initialized. ( P. 150)
■ 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.)
CAUTION
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery:
● Make sure the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any other than the intended terminal.
● 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.
