Driving and Operating . 9-9 Keep your eyes moving - scan the road ahead and to the sides. Check the rearview mirror and vehicle instruments often. { WARNING Coasting downhill in N (Neutral) or with the vehicle turned off is dangerous. The brakes will have to do all the work of slowing down the vehicle and could become too hot. Hot brakes may not be able to slow the vehicle enough to maintain speed and control. You could crash. Always have the vehicle running and in gear (preferably LOW range) when going downhill. This will allow the electric drive unit to assist in slowing and maintaining speed. . . . Pay attention to special road signs (falling rocks area, winding roads, long grades, passing or no-passing zones) and take appropriate action. Hill and Mountain Roads Driving on steep hills or through mountains is different than driving on flat or rolling terrain. See "Mountain Mode" under Driver Selected Operating Modes on page 9‑22. Tips for driving in these conditions include: . Winter Driving Driving on Snow or Ice Drive carefully when there is snow or ice between the tires and the road, creating less traction or grip. Wet ice can occur at about 0°C (32°F) when freezing rain begins to fall, resulting in even less traction. Avoid driving on wet ice or in freezing rain until roads can be treated with salt or sand. Drive with caution, whatever the condition. Accelerate gently so traction is not lost. Accelerating too quickly causes the wheels to spin and makes the surface under the tires slick, so there is even less traction. Keep the vehicle serviced and in good shape. Check all fluid levels and brakes, tires, cooling system, and electric drive unit. Keep the vehicle in gear when going down steep or long hills. . . . Stay in your own lane. Do not swing wide or cut across the center of the road. Drive at speeds that let you stay in your own lane. Top of hills: Be alert - something could be in your lane (stalled car, accident).
