You'll need to:
1. Open the hood: Locate the hood release lever (usually inside the car near the steering column or under the dashboard) and pull it to release the hood. Prop the hood open using the hood prop rod.
2. Locate the reservoir: Look around the engine compartment. The rear washer fluid reservoir is usually smaller than the front one and may be labeled or have a diagram indicating its purpose. It's often located near the back of the engine compartment, sometimes near the firewall. It might be a little harder to find than the main windshield washer fluid reservoir.
3. Remove the cap: Unscrew the cap carefully.
4. Add washer fluid: Use a funnel to add washer fluid designed for winter use if necessary (especially if you live in a cold climate). Don't overfill; stop when the fluid is near the top of the reservoir.
5. Replace the cap: Securely tighten the cap back on.
If you can't find it:
* Consult your owner's manual: The manual will have diagrams and instructions specifically for your 2013 Jeep Wrangler. This is the best resource for accurate location information.
* Search online: Search for "2013 Jeep Wrangler rear washer fluid reservoir location" on image search engines like Google Images or Bing Images. Seeing pictures from other owners might help you pinpoint it.
Remember to use only washer fluid designed for your vehicle; never use plain water, especially in freezing temperatures. Using the wrong fluid can damage the system.
