7-2. Steps to take in an emergency
Starting the engine when the battery is
■
discharged
The engine cannot be started by push-start-
ing.
To prevent battery discharge
■
Turn off the headlights and the audio sys-
●
tem while the engine is off.
● Turn off any unnecessary electrical com-
ponents when the vehicle is running at a
low speed for an extended period, such
as in heavy traffic.
Charging the battery
■
The electricity stored in the battery will dis-
charge gradually even when the vehicle is
not in use, due to natural discharge and the
draining effects of certain electrical appli-
ances. 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 dis-
■
charged
● In some cases, it may not be possible to
unlock the doors using the smart access
system with push-button start 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 recon-
nected, the system will return to the
mode it was in before the battery was dis-
charged. Before disconnecting the bat-
tery, 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.
● The power back door must be initialized.

WARNING
Avoiding battery fires or explosions
■
Observe the following precautions to
prevent accidentally igniting the flamma-
ble gas that may be emitted from the bat-
tery:
● Make sure each jumper cable is con-
nected to the correct terminal and that
it is not unintentionally in contact with
any other than the intended terminal.
● Do not allow the other end of the
jumper cable connected to the "+" ter-
minal to come into contact with any
other parts or metal surfaces in the
area, such as brackets or unpainted
metal.
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.
Battery precautions
■
The battery contains poisonous and cor-
rosive acidic electrolyte, while related
parts contain lead and lead compounds.
Observe the following precautions when
handling the battery:
● When working with the battery, always
wear safety glasses and take care not
to allow any battery fluids (acid) to
come into contact with skin, clothing
or the vehicle body.
● Do not lean over the battery.
● In the event that battery fluid comes
into contact with the skin or eyes,
immediately wash the affected area
with water and seek medical attention.
Place a wet sponge or cloth over the
affected area until medical attention
