Additional Checks
WARNING: This page is about a different car, the 2003 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
- Check the clutch adjustment in vehicles equipped with a manual transmission. See appropriate FWD article in CLUTCHES.
- Check the transmission shift pattern and the Torque Converter Clutch (TCC) operation in vehicles equipped with an automatic transmission. See appropriate DIAGNOSIS article in AUTOMATIC TRANSMISSIONS.
- Check for dragging brakes.
- Check for uneven or premature tire wear. A suspension misalignment can cause reduced fuel economy. See SPECIFICATIONS & PROCEDURES - VIBE article under WHEEL ALIGNMENT in SUSPENSION.
- Verify tires and wheels are similar to OEM. Wide performance tires create more drag and taller tires can cause odometer discrepancies.
- Check for a low mileage engine. Fuel economy may not be near expected levels until the engine has had 3000-5000 miles (5000-8000 km) to break in.
- Check for add-on equipment like luggage racks and carriers. Wind resistance can lower fuel economy.
- Check for Technical Service Bulletins and for any updates or information.
