Parking on Hills
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 darnaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
.I. Apply your regular brakes, but don’t shift into
.. !PARK (P) yet.
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 PARK
(P).
When You Are Ready to Leave After
Parking o,n a
Hill
1. Apply your regular brakes and hold the pedal down
8’. .
while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is dear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for,more
.on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t oyerfill),
engine oil, belt, cooling system, .and brake adjustment.
Each of these
is covered in this manual, and the Index
will help you find them quickly. If you’re trailering, it’s
a good idea
to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.

NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come
out and fall on hot engine parts
or exhaust system parts, starting a fire. Be sure to
get an accurate reading if
you check your
transaxle fluid.
Wait at least 30 minutes before, checking the transaxle
fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
In heavy traffic -- especially in hot weather.
a ' While pulling a trailer.
To get the right reading; the fluid should be at normal
operating temperature, which is 180°F to 200°F (82°C
to 93°C).
Get the vehicle warmed up by driving about 15 miles
(24
km) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F (lO"C), you may have
to drive longer.

Brakes
Brake Master Cylinder
Your brake master cylinder is here. It is filled with
DOT-3 brake fluid. should
have your brake system fixed, since a leak means
that sooner or later your brakes won’t work well, or
won’t work at all.
So, it isn’t a good idea to “top off’ I I
your brake fluid. Adding brake fluid won’t correct a
leak. If you add fluid when your linings are worn, then
you’ll have too much fluid when you get new brake
.linings.
You should add (or remove) brake fluid, as
necessary, only when work is done on the brake
hydraulic system.
There
are only two reasons why the brake fluid level in When your brake fluid falls to a low level, your brake
