You really should not park your vehicle, with a trailer
attached,
on a hll. If something goes wrong, your rig
could
start to move. People can be injured, and b.oth
your vehicle and the trailer can be damaged.
But
if you ever have to park your rig on a hill, here’s
how to do it:
1.
2.
3.
4.
5.
6.
Apply your regulafbrakes, but don’t shift into
PARK (P) yet, or into gear for a manual
transmission. When parking uphill, turn your wheels
away from the curb. When parking downhill,
turn
your wheels into the curb.
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your
parking brake, and then shift into PARK (P), or
REVERSE (R) for a manual transmission.
If.you have a four-wheel-drive vehicle with
a
manual transfer case shift lever, be sure the transfer
case
is in a drive gear -- not in NEUTRAL (N).
Release the regular brakes.
It can be dangerous to get out of pur vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set.
Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly.
You or others could be
injured.
To be sure your vehicle won’t move, even
when yoa’re
on fairly level ground, use the steps
that follow.
If you have four-wheel drive with a manual
transfer case shift lever and your transfer case
is
in NEUTRAL (N), your vehicle will be free to
roll, even if your shift lever is in PARK (P). So, be
sure the transfer ca’se is in a drive gear
-- not in
NEUTRAL (N).
