Starting and Operating Instructions
You should not park vehicles with
trailers on a grade (hill). However,
if you must park on a grade, follow
these steps:
1. Apply your regular brakes, but
don't shift into P (Park) for an
automatic transmission or into
gear for a manual transmission
yet.
If the vehicle is facing down-
hill, turn the wheels toward
the curb. If it is facing uphill,
turn the wheels toward traffic.
2. Have someone place chocks
under the trailer wheels.

3. When the wheel chocks are in
place, release the regular
brakes until the chocks absorb
the load.
4. Reapply the regular brakes.
Then apply your parking
brake, and then shift to P
(Park) for an automatic trans-
mission or into gear for a
manual transmission.
5. Release the regular brakes.
Your vehicle is equipped with a Hill
Start Assist feature, which may be
useful when stopped on a grade.
See "Hill Start Assist" earlier in this
section.
When you are ready to leave after
parking on a hill, be sure to hold
the regular brake pedal down
while you start the engine, shift
into gear and release the parking
brake.
Let up on the brake pedal.
Drive slowly until the trailer is clear
of the chocks.
Stop and have someone pick up
and store the chocks.
