When turning, drive slightly beyond the normal
turning point so the trailer wheels will clear
curbs or other obstructions.
When stopped in traffic for long periods of time
in hot weather, place the gearshift selector lever
in P (Park) to increase the engine idle speed.
This aids in engine cooling and air conditioner
efficiency. If the engine overheats, move the
function selector knob to VENT to stop the
compressor and increase the engine speed for a
short time.
Vehicles with trailers should not be parked on a
grade. However, if you must park on a grade,
place wheel chocks under the trailer's wheels as
follows:
Apply the foot service brakes and hold.
Have another person place the wheel chocks
under the trailer wheels.
With the chocks in place, release the foot
service brakes, making sure the chocks are
holding.
For automatic transmissions — apply the
parking brake by pressing the service brake
pedal down firmly with your right foot while
applying the parking brake pedal with your
left foot.
For manual transmissions — apply the
service brake and shift into N (NEUTRAL)
while still maintaining pressure on the service
brake pedal. Set the parking brake fully.
