2-5. Driving information l Take care when passing other vehicles. Passing requires considerable distance. After passing a vehicle, do not forget the length of your trailer, and be sure you have plenty of room before changing lanes. l In order to maintain engine braking efficiency, do not use the transmission in D (automatic transmission) or 5 (manual transmission). l Due to the added load of the trailer, your vehicle's engine may overheat on hot days (at temperatures over 85° F [30° C]) when driving up a long or steep grade. If the engine coolant temperature gauge indicates overheating, immediately turn off the air conditioning (if in use), pull your vehicle off the road and stop in a safe spot. (→P. 329) l Always place wheel blocks under both the vehicle and the trailer wheels when parking. Apply the parking brake firmly, and put the transmission in P (automatic transmission) or in 1 or R (manual transmission). Avoid parking on a slope, but if unavoidable, do so only after performing the following: Apply the brakes and keep them applied. Have someone place wheel blocks under both the vehicle and trailer wheels. When the wheel blocks are in place, release the brakes slowly until the blocks absorb the load. Apply the parking brake firmly. Shift into 1 or R (manual transmission) or P (automatic transmission) and turn off the engine. 160
