To refill the fluid:
1. Open the hood: Locate the hood release lever inside the vehicle (usually near the steering wheel or under the dashboard) and pull it to release the hood latch. Then, lift the hood.
2. Locate the washer fluid reservoir: It's a usually a translucent plastic bottle, often found near the front of the engine compartment. It will likely be labeled "Washer Fluid" or have a similar marking. The cap will typically be a screw-top style.
3. Remove the cap: Unscrew the cap and carefully lift it off.
4. Add washer fluid: Use a funnel to pour the correct type of washer fluid into the reservoir. Do not overfill – the reservoir has a maximum fill line; avoid exceeding it.
5. Replace the cap: Screw the cap back on tightly.
6. Test the system: Turn on your rear washer to make sure the fluid is flowing to the rear wiper.
