Park your vehicle on level ground and turn off the engine. This is important to prevent the fluid from spilling out of the reservoir.
Locate the rear wiper fluid reservoir. In the Toyota Matrix, it is usually located in the trunk, on the driver's side. There will be a black plastic cap labeled "Wiper Fluid" on the reservoir.
Remove the cap from the reservoir. Be careful not to spill any fluid.
Fill the reservoir with wiper fluid. You can use any brand of wiper fluid, but it is recommended to use a fluid that is specifically designed for your vehicle's climate.
Replace the cap on the reservoir. Make sure the cap is on tightly to prevent the fluid from leaking out.
Test the rear wiper. Turn on the rear wiper and spray the fluid to make sure it is working properly.
Here are some additional tips for refilling the rear wiper fluid in your Toyota Matrix:
* If you are having trouble finding the rear wiper fluid reservoir, consult your vehicle's owner's manual.
* If you spill any wiper fluid, clean it up immediately to prevent it from damaging your vehicle's paint.
* It is a good idea to refill the rear wiper fluid regularly, especially during the winter months when it can freeze.
