Maintenance -> Battery for Your Hyundai Tucson SUV 2020

BATTERY  
Batteries contain sulfu-  
ric acid which is highly  
corrosive. Do not allow  
acid to contact your  
eyes, skin or clothing.  
The electrical ignition system  
works with high voltage.  
NEVER touch these compo-  
nents with the engine running  
or when the ignition switch is  
in the ON position.  
WARNING  
To prevent SERIOUS INJURY or  
DEATH to you or bystanders,  
always follow these precautions  
when working near or handling  
the battery:  
If acid gets into your eyes, flush  
your eyes with clean water for at  
least 15 minutes and get imme-  
diate medical attention. If acid  
gets on your skin, thoroughly  
wash the area. If you feel pain or  
a burning sensation, get med-  
ical attention immediately.  
Always read and follow  
instructions  
carefully  
when handling a battery.  
Wear eye protection  
designed to protect the  
eyes from acid splashes.  
When lifting a plastic-cased  
battery, excessive pressure  
on the case may cause battery  
acid to leak. Lift with a battery  
carrier or with your hands on  
opposite corners.  
Do not attempt to jump start  
your vehicle if your battery is  
frozen.  
NEVER attempt to recharge  
the battery when the vehicle’s  
battery cables are connected  
to the battery.  
Keep all flames, sparks,  
or smoking materials  
away from the battery.  
Hydrogen is always pres-  
ent in battery cells, is  
highly combustible, and  
may explode if ignited.
