fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will
be operating your vehicle in an area where the
temperature may fall below freezing, use a fluid that has
sufficient protection against freezing.
Adding Washer Fluid
Your vehicle has a low washer fluid message that
comes on when the washer fluid is low. The message is
displayed for 15 seconds at the start of each ignition
cycle if the fluid is low. When the LOW WASHER FLUID
message is displayed, you will need to add washer
fluid to the windshield washer fluid reservoir.
The windshield washer
fluid reservoir is located in
the engine compartment
on the passenger’s side of
the vehicle. See Engine
Compartment Overview on
page 5-12 for reservoir
location.
