Downshifting with the paddle shifter
allows you to increase the engine
braking when going down steep or
long hills, and provides more power
when climbing uphills. You can
upshif t the transmission manually to
reduce the rpm. Driving in the
higher gear helps f uel economy.
The transmission also shif ts
automatically as the vehicle comes to
a complete stop. It downshif ts to f irst
gear when the vehicle speed reaches

If you must stop when f acing uphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
placebypressingontheaccelerator,
as this can cause the automatic
transmission to overheat.Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause the trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.
Always drive slowly and have
someone guide you when backing up.
Grip the of the steering
