2022 HYUNDAI SONATA HYBRID 12 volt battery

Emergency situations
7-4
Before Jump Starting
This vehicle does not have a regular 12V
battery that needs periodic replacement.
It is lithium ion polymer type integrated
into the HEV high voltage battery. The
vehicle has a 12V battery protection
system that cuts 12V battery from vehicle
draw to prevent full discharge.
Using the 12V battery reset switch
ODN8HQ019028
1. Press the 12V Battery Reset switch to
reconnect the 12V battery.
2. Start the vehicle within 15 seconds of
pressing the 12V Battery Reset switch.
3. After starting the vehicle
( indicator on), operate the vehicle
safely outdoors in ready mode
stopped and/or drive it for 30 minutes
total to charge the 12V battery fully. If you do not start the vehicle
immediately after pressing the 12V
Battery Reset switch, the power of 12V
battery is automatically disconnected
after few seconds to save the 12V battery
from additional discharge. If the 12V
battery is disconnected prior to starting
the vehicle, press the 12V Battery Reset
switch again and then immediately start
the vehicle as explained.
Repeated use of the 12V Battery Reset
switch without a sufficient engine
ON cycle (30 Min+) may cause over
discharge of the 12V battery, which will
prevent the vehicle from starting. If the
12V battery is over discharged to a point
that the reset does not work, try to jump-
start the vehicle.
Information
After starting the vehicle
( indicator on), the 12V battery is being
charged whether the engine is running or
not. Although there is no engine sound, it
is unnecessary to depress the accelerator
pedal.
The following items may need to be reset
after the battery has been discharged or
the battery has been disconnected.
See chapter 4 and 5 for:
• Power Windows
• Trip Computer
• Climate Control System
• Clock
• Audio System
• Sunroof

assisting vehicle (3).
3. Disconnect the second jumper cable
from the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
4. Disconnect the other end of the
jumper cable from the red, positive (+)
jumper terminal of your vehicle (1).
Information
The voltage range of the charger should be
13.3~14V and its current range should be
less than 60A. (13.8V is recommended).
CAUTION
• The use of an improper charger
with a voltage and current range
higher than specified may cause
overheating and damage to the 12V
battery.
• The use of an incorrect charger will
lead to a power shut-off to save the
12V battery. Stop using the incorrect
charger once the power of the
vehicle is shut off.
Information
An inappropriately disposed battery can be harmful to
the environment and human
health. Dispose of the battery
according to your local law(s) or
regulations.
NOTICE
To prevent damage to your vehicle:
• Only use a 12-volt power supply
(battery or jumper system) to jump
start your vehicle.
• Do not attempt to jump start your
vehicle by push-starting.
CAUTION
Do not jump start another vehicle with
your hybrid vehicle. Jump starting
another vehicle will damage the
hybrid vehicle’s 12 volt battery (lithium
polymer type).
