The warning will not go off until you
add fuel. It will also come on for a few
seconds when

ignition as a check to show you it is
working. If it doesn’t come on then,
have it fixed.
Engine Coolant Temperature Warning Light
This light tells you that your engine
coolant has overheated or your radiator
cooling fan is not working. If you have
been operating your vehicle under

Heating and Ventilation
When you don’t need to cool the
outside air, use these next settings.
You
can leave the air as it is or heat it.
The air conditioner compressor doesn’t
run in the
VNT and HTR settings. This
reduces the engine load, resulting in
improved fuel economy (gas mileage).
VNT (Vent): For mild outside
temperatures, when little heating or
cooling is needed, push
VNT. Air flow
is through the instrument panel outlets.
Slide the temperature control lever to a
comfortable level.
HTR (Heater): When outside
temperatures are cold, push
HTR. This
will send most of the heated air through
the ducts near the floor. The rest will
come out of the defroster vents and side
window defogger vents.
Defogging and Defrosting
There are two settings for clearing your
windows. For each setting, adjust the
temperature control
as desired. The air
conditioner compressor will run in
these settings to remove moisture from
the air when the temperature is above
freezing.
This setting allows half
of
\p the air to flow to the floor
heater ducts, and half to go
to the windshield and side
window vents located in
the windshield pillars. Use
this setting to warm
passengers while keeping
the windshield clear. The setting directs
90% of the air
through the defroster vents and the side
window vents, and
10% to the floor.

Your Driving and the Road
Driving with a Trailer (CONT.)
Making Turns
When you’re turning with a trailer,
make wider turns than normal. Do this
so your trailer won’t strike soft
sh’oulders, 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.
Your vehicle has bulb warning lights.
When you plug trailer lights into your
vehicle’s lighting system, its bulb
warning lights may not let you know if
one of your lights goes out.
So, when
you have trailer lights plugged in, be
sure
to check your vehicle and trailer
lights
from time to time to be sure
they’re all working. Once
you
disconnect the trailer lights, the bulb
warning lights again can tell you if one
of your vehicle lights is out.
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 kwh) to reduce the possibility of
engine and transaxle overheating.
If you are towing a trailer and you have
an automatic transaxle with Overdrive,
it’s best to drive in
D instead of (or
as you need to, a lower gear). This will
minimize heat build-up and extend the
life of your transaxle.
