A CAUTION:

“Riding” your brakes can cause them to overheat to the point
that they won’t work well.
You might not be able to stop your
vehicle in time to avoid an accident.
If you “ride” your brakes,
they
will get so hot they will require a lot of pedal force to slc
you down. Avoid “riding” the brakes.

You’ll need more passing distance up ahead when you’re towing a trailer.
And, because you’re a good deal longer, you’ll need
to go much farther
beyond the passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer to the left, just move that hand to the left.
To move the trailer to
the right, move your hand to
the right. Always back up slowly and, if
possible, have someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns than normal. Do
this so your trailer won’t strike soft shoulders, curbs, road signs, trees, or
other objects. Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a different turn signal
flasher and extra wiring. The green arrows on your instrument panel will
flash whenever
you signal a turn or lane change. Properly hooked up, the
trailer lights will also flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the green arrows on your instrument panel will
flash for turns
even if the bulbs on the trailer are burned out. Thus, you
may think drivers behind you are seeing your signal when they are not.
It’s important to check occasionally to be sure the trailer bulbs are still
working.
Driving On Grades
Reduce speed and shift to a lower gear before you start down a long or
steep downgrade.
If you don’t shift down, you might have to use your
brakes
so much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your speed to around
45
mph (70 km/h) or less to reduce the possibility of engine and transaxle
overheating.

If No Steam Is Coming From Your Engine:
If you get the overheat warning but see or hear no steam, the problem
may not be too serious. Sometimes the engine can get a little too hot
when you:
e Climb a long hill on a hot day.
Stop after high speed driving.
e Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign
of steam, try this for a
minute or
so:
1. Turn off your air conditioner.

Downloaded from www.Manualslib.com manuals search engine 2. Turn on your heater to full hot at the highest fan speed and open the
window as necessary.
3. Try to keep your engine under load (in a drive gear where the engine
runs slower).
If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower
for about ten minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your vehicle right
away.
If there’s still no sign of steam, you can idle the engine for two or three
minutes while you’re parked, to see
if the warning stops. But then, if you
still have the warning, TURN
OFF THE ENGINE AND GET
EVERYONE OUT OF THE VEHICLE until it cools down.
You may decide not to lift the hood but to get service help right away.
