2006 Cadillac STS - Electric Vehicle Guide
The 2006 Cadillac STS belongs to a Cadillac STS lineup that Know Your Ride tracks across 3 model years, from 2005 to 2007. It is an all-electric vehicle, so it skips the oil changes, spark plugs and exhaust-system service of a combustion STS entirely. It is configured as rear-wheel drive with an automatic (s5). The 2006 sits mid-run, with both earlier (2005) and later (2007) STS model years also documented.
The high-voltage battery is covered for 8 years or 100,000 miles, separate from the bumper-to-bumper warranty. Routine upkeep centers on tire rotation, DOT 3 brake fluid, Dex-Cool battery/cabin coolant, cabin air filters and brake service rather than engine oil. Know Your Ride lists 13 scheduled maintenance items for this vehicle, the earliest interval falling at 7,500 miles. Documented torque values include lug nut 100 ft-lb.
