possible injury. Always use the
proper GM approved brake fluid.

Immediately wash off any painted

Battery - North America

The original equipment battery is
maintenance free. Do not remove
the cap and do not add fluid.
This vehicle has a standard 12-volt
battery under the hood. See Engine
Compartment Overview 0 216.
Refer to the replacement number
shown on the original battery label
when a new 12-volt battery is
needed.
Stop/Start System
If equipped with the 2.5L L4 Engine,
the vehicle has a Stop/Start system
to shut off the engine to help
conserve fuel. See Starting the
Engine 0 169.
Vehicles with Stop/Start have an
Absorbed Glass Mat (AGM) 12-volt
underhood battery. Installation of a
standard 12-volt battery will result in
reduced 12-volt battery life.
There is also an auxiliary AGM
battery behind the access panel in
the left rear of the trunk. This
battery is for managing the Stop/
Start auxiliary loads and is not to be
used for any other purpose. See
your dealer if the auxiliary battery
needs service.
When using a 12-volt battery
charger on the 12-volt AGM battery,
some chargers have an AGM
battery setting on the charger.
If available, use the AGM setting on
the charger, to limit charge voltage
to 14.8 volts.
