WHAT TO DO IN EMERGENCIES WARNING! (Continued) • If it is necessary to retrieve the spare tire from under the vehicle on the side of the vehicle close to moving traffic, pull far enough off the road to avoid the danger of being hit. • Carefully follow these tire changing procedures to help prevent personal injury or damage to your vehicle: Always park on a firm, level surface as far from the edge of the roadway as possible before raising the vehicle. • Raising the vehicle higher than necessary can make the vehicle less stable and could cause it to slip off the jack and hurt someone near it. Raise the vehicle only enough to remove the tire. • A loose tire or jack, thrown forward in a collision or hard stop, could endanger the occupants of the vehicle. Always stow the jack parts and the spare tire in the places provided. JUMP-STARTING • If your vehicle has a discharged battery it can be jump-started using a set of jumper cables and a battery in another vehicle or by using a portable battery booster pack. • Jump-starting can be dangerous if done improperly so please follow the procedures in this section carefully. NOTE: When using a portable battery booster pack follow the manufacturer's operating instructions and precautions. Preparations for Jump-Start • The battery in your vehicle is located under the passengers front seat. There are remote locations under the hood to assist in jump starting. • Set the parking brake, shift the automatic transmission into PARK and turn the ignition to LOCK. • Turn off the heater, radio, and all unnecessary electrical accessories. • Remove the protective cover over the remote positive (+) battery post. Pull upward on the cover to remove it. • If using another vehicle to jump-start the battery, park the vehicle within the jumper cables reach, set the parking brake and make sure the ignition is OFF. 71
