This gage shows the engine coolant temperature.
To prevent engine overheating, the air conditioning
compressor will turn off automatically just prior to the
gage pointer entering the shaded area.As the engine cools down, the air conditioning
compressor will automatically turn back on. On vehicles
equipped with the DIC, the message ENGINE HOT... A/C
DISABLED will appear in the DIC display and a warning
chime will sound.
If the gage pointer moves into the shaded area, your
engine is too hot. On vehicles equipped with the
systems monitor, the CHECK GAGES light will come on
and a warning chime will sound.
On vehicles with a DIC, a CHECK GAGES
TEMPERATURE message will be displayed and a
warning chime will sound. SeeDIC Warnings and

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal asher and/or extra wiring. Check
with your dealer. All of the electrical circuits required for
your trailer lighting system can be accessed at the
left rear lamp connector. This connector is located under
the carpet on the driver’s side in the rear corner of
your trunk compartment. The arrows on your instrument
panel will ash whenever you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
ash, telling other drivers you are about to turn,
change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will ash 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
is important to check occasionally to be sure the trailer
bulbs are still working.
Your vehicle has bulb warning lights. When you plug a
trailer lighting system into your vehicle’s lighting
system, its bulb warning lights may not let you know if
one of your lamps goes out. So, when you have a trailer
lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they are all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you if one
of your vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you do not 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 to THIRD (3) and
reduce your speed to around 45 mph (70 km/h) to
reduce the possibility of the engine and transaxle
overheating.
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.
4-44

But if you ever have to park your rig on a hill, here is
how to do it:
1. Apply your regular brakes, but do not 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).
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine.
Shift into a gear.
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear 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 are
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle uid (do not overll),
engine oil, drive belt, cooling system and brake system.
Each of these is covered in this manual, and the Index
will help you nd them quickly. If you are trailering, it is a
good idea to review this information before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-29.
