Turn Signals When Towing a Trailer When you tow a trailer, your vehicle has to have extra wiring and a heavy-duty turn signalflasher (included in the optional trailering package). The green arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, thetrailer lamps will also flash, telling other drivers you're about to turn, change lanes or stop. When towing a trailer, the green arrows on your instrument panel willflash for turns evenif the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signalwhen they are not. It's important to check occasionally to be sure the trailer bulbs are still working. On a long uphill grade, shift down and reduce your speed to around45 mph (70 k d h ) to reduce the possibility of engine and transmission overheating. If you have an automatic transmission, you should use DRIVE (D) when towing a trailer. Operating your vehicle in DRIVE (D) when towingtrailer will a minimize heat buildup and extend the life your of transmission. Or,if you have a manual transmission, it's better not to use FIFTH(5), just drive in FOURTH (4) (or, as you need to, a lower gear). When towing at high altitude on steep uphill grades, at consider the following: Engine coolant will boil a lower temperature thanat normal altitudes. If you turn your engine off immediately after towing at highaltitude on steep uphill grades, your vehiclemay show signs similar to engine overheating. To avoid this, let the engine run while parked (preferablyon level ground) with the automatic transmission in PARK (or the (P) manual transmission outof gear and the parking brake applied) for a few minutes before turning the engine off. If you do get the overheat warning, see "Engine Overheating'' in the Index. Driving On Grades Reduce speed andshift to a lower gear before you start down a long or steep downgrade. If you don't shift down, you might have to use your brakesso much that they would get hot and longer work well, no 4-54
