At very steep inclines, not manageable with selector lever in position "1", switch transfer case to LOW RANGE, see page 209 for instructions on how to engage LOW RANGE. When going down a long hill, shift into a lower gear and use the engine's braking effect. Avoid riding the brakes, thus overheating the vehicle and trailer brakes. If the engine coolant rises to an extremely high temperature (coolant temperature needle approaching the red zone) when the air conditioner is on, turn off the air conditioner. Engine coolant heat can be additionally vented by opening the windows, switching the climate control fan speed to high and setting the temperature control to the maximum hot position. Extreme care must be exercised since your vehicle with a trailer will require additional passing distance ahead than when driving without a trailer. Because your vehicle and trailer is longer than your vehicle alone, you will also need to go much farther ahead of the passed vehicle before you can return to your lane. Parking Warning! To reduce the risk of personal injury, or damage to the vehicle powertrain, as a result of vehicle/trailer movement, always: 1. Keep right foot on brake pedal. 2. Shift gear selector lever to position "N". 3. Have a second person place wheel chocks on downhill side of left and right trailer wheels. 4. Slowly release brake pedal and let vehicle and trailer roll into chocks until stopped. 5. Firmly depress parking brake pedal. 6. Move gear selector lever to position "P". 7. On inclines turn front wheels towards the road curb. Driving instructions Instruments and controls Operation Driving 195 Instrument cluster display Practical hints Car care Technical data Index
