240 MAINTAINING YOUR VEHICLE Check the battery every four to six weeks to ensure that the voltage is above 12.40. Voltage will drop more rapidly in hot temperatures. If battery voltage drops below 12.40, follow the battery recharge procedure in the Service Manual. • Check that the radiator coolant level of protection is to at least -20°F (-29°C). • Block the wheels. Do not apply the parking brake. • Make sure that all tires are inflated to the optimum pressure. • Cut blocks of plywood about the same size of the tires. Cover each block with indoor/outdoor carpeting and place them between the tires and concrete. This will prevent tire flat spotting. • For long term storage, remove the tires and put the vehicle up on blocks. Stack the tires on plywood and cover with a tarp to prevent flat spotting. • Move the wiper blades away from the windshield. NOTE: To help prevent the battery from discharging during shorter periods of inactivity, perform the following: 1. Make sure that the rear liftgate/decklid, hood, and doors are completely closed. 2. Make sure that the remote transmitter is operating and that the battery is good. 3. Make sure that the hood, rear liftgate and door switches are in adjustment. 4. Use the remote transmitter to set the alarm.
