Take a closer look under the hood

One such technology is DEX-COOL TM , a long lasting, corrosion inhibiting engine coolant that doesn't contain any phosphates, nitrates or silicates.

DEX-COOL requires changing only once every five years (or every 240,000 km)* instead of every two years like regular coolants. And it's recyclable, which means you're discarding less hazardous material into the atmosphere and consuming less non-renewable resources.

DEX-COOL is now a standard production product in all General Motors vehicles†, a testament to its efficiency and reliability.

Another such technology is the oil-life monitoring system**, which allows drivers to potentially conserve nearly 38 million litres of oil annually. The system senses when the oil in a vehicle is nearing the end of its useful life and notifies the driver with a "change oil" message on the dashboard, ultimately protecting the engine from premature wear.

Rather than depending on fixed oil change schedules that may not be suitable for all situations, the monitoring system customizes the oil change schedule based on the vehicle's engine and transmission type, and the individual's driving habits. Visit your vehicle's maintenance guideor find a Goodwrench dealernear you for more information.

These initiatives are part of GM's continuing efforts to provide owners with a more hassle-free ownership experience and to manufacture more environmentally friendly vehicles. Learn more about these technologies by clicking here.

Warning, do not mix DEX-COOL with other coolants.}
