Warning
If too much brake fluid is added, it can
spill on the engine and burn, if the
engine is hot enough. You or others could
be burned, and the vehicle could be
damaged. Add brake fluid only when
work is done on the brake hydraulic
system.
When the brake fluid falls to a low level,
the brake warning light comes on. See
Brake fluid absorbs water over time which
degrades the effectiveness of the brake fluid.
Replace brake fluid at the specified intervals
to prevent increased stopping distance. See
.

The vehicle has a Stop/Start system to shut
off the engine to help conserve fuel. See
.
The vehicle has an Absorbed Glass Mat
(AGM) 12-volt battery. Installation of a
standard 12-volt battery will result in
reduced 12-volt battery life.
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.
