Engine Coolant

The cooling system in the vehicle is filled with DEX-COOL® engine coolant. The coolant is designed to remain in the vehicle for 5 years or 240 000 km (150,000 mi), whichever occurs first.

The following explains the cooling system and how to check and add coolant when it is low. If there is a problem with engine overheating, see Engine Overheating on page 10‑18.
