GMC Terrain: Vehicle Checks / Washer Fluid
What to Use
When windshield washer fluid is
needed, be sure to read the
manufacturer's instructions before
use. If operating the vehicle in an
area where the temperature may fall
below freezing, use a fluid that has
sufficient protection against
freezing.
Adding Washer Fluid

Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. See Engine
Compartment Overview for
reservoir location.
Caution
- Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.
- Do not use engine coolant
(antifreeze) in the
windshield washer. It can
damage the windshield
washer system and paint.
- Do not mix water with
ready-to-use washer fluid.
Water can cause the
solution to freeze and
damage the washer fluid
tank and other parts of the
washer system.
- When using concentrated
washer fluid, follow the
manufacturer instructions for
adding water.
- Fill the washer fluid tank
only three-quarters full when
it is very cold. This allows
for fluid expansion if
freezing occurs, which could
damage the tank if it is
completely full.
The vehicle has an engine coolant
temperature gauge on the
instrument cluster and overheat
messages in the Driver Information
Center (DIC) to warn of engine
overheating...
