When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If you turn your
engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating. To avoid this, let the
engine run while parked (preferably on level ground)
with the automatic transmission in PARK (P) (or
the manual transmission out of gear and the parking
brake applied) for a few minutes before turning the
engine off. If you do get the overheat warning,
seeEngine Overheating on page 5-29.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both 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. Apply your regular brakes, 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.
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 into PARK (P), or
REVERSE (R) for a manual transmission. See
Parking Brake on page 2-32for more information.
5. If you have a four-wheel-drive vehicle, be sure
the transfer case is in a drive gear and not in
NEUTRAL. SeeFour-Wheel Drive on page 2-28
for more information.
6. Release the regular brakes.

For regular and extended
cab vehicles, the jack and
wheel blocks are located
under the cover at the
center of the vehicle
behind the front seats.
To access the tools:
1. Move the seats forward
to access the cover.2. Turn the wing nut on the cover counterclockwise
to remove it.
For crew cab models, reach under the rear seat
to access the jack and wheel blocks. To reinstall
the jack and wheel block assembly in the mounting
bracket, insert the tabs into the jack base by
pushing the blocks up into the assembly. The outer
hole in the jack base aligns with the tab on the
bracket. When reinstalling, make sure the jack
is secure, but do not overtighten the jack in
the bracket.
3. Remove the wheel blocks and the wheel block
retainer by turning the wing nut counterclockwise.
4. Put the wheel blocks at the front and rear of the tire
farthest away from the one being changed. That
would be the tire on the other side, at the opposite
end of the vehicle.
5. Locate the wing nut used to retain the storage bag
and tools which is under the front passenger’s seat.
Remove it by turning the wing nut counterclockwise.
Use the jack handle extensions and the wheel wrench
to remove the underbody-mounted spare tire. Regular/Extended Cab
