📋 Before You Begin

• 🅿️ Park your Trax outdoors on level ground, shift into Park, apply the parking brake, and switch off the engine.
• ⏳ Allow hot exhaust components to cool before working near the rear of the vehicle.
• 🔍 Compare the new cap with the old one. The sealing gasket, threaded section, and tether attachment should match.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Fuel Door

• Put on the nitrile gloves and safety glasses.
• Press and release the rear edge of the fuel door by hand. The fuel door is on the passenger-side rear quarter panel.

Step 2: Remove the Old Fuel Cap

• Turn the old cap counterclockwise by hand until it releases from the filler neck.
• Remove it slowly to allow any fuel-tank pressure to escape.
• Do not insert the small flat-blade screwdriver into the filler neck.

Step 3: Disconnect the Cap Tether

• The tether is the flexible strap that prevents the cap from being lost.
• If the tether has a slotted rubber loop, stretch and slide it off its mounting post by hand.
• If it uses a push-in retainer, carefully lift the retainer edge with the small flat-blade screwdriver, then pull it out by hand.
• Do not force the retainer against the painted fuel-door pocket.

Step 4: Attach the New Tether

• Fit the new tether onto the same mounting point by hand.
• For a loop-style tether, press the loop completely over the mounting post.
• For a push-in retainer, align it with the original hole and press it firmly into place by hand.
• Make sure the tether is not twisted and cannot become trapped by the fuel door.

Step 5: Install the New Fuel Cap

• Place the new cap squarely against the filler neck by hand.
• Turn it clockwise until it clicks once. Additional clicks are harmless, but one clear click confirms the cap is tightened.
• No numerical torque specification or torque wrench is required.
• Start straight to avoid damaging the threads.

Step 6: Close the Fuel Door

• Position the tether inside the filler pocket by hand so it does not hang outside.
• Close the fuel door and press its rear edge until it sits flush with the body.

✅ After Repair

• 🚗 Start your Trax and confirm there is no strong fuel smell around the filler door.
• 💡 If a loose-cap message was displayed, it may clear after the cap is tightened and the vehicle completes several driving cycles.
• 🔎 If the check-engine light remains on, the evaporative-emissions system should be scanned for diagnostic trouble codes. Do not erase codes before recording them.
• ⚠️ Stop driving and inspect the installation if liquid fuel leaks from the filler area.
