Standard Cluster Digital Cluster
If you have a standard cluster, this gage shows the engine coolant
temperature.
If the gage pointer moves into the red area, your engine is too
hot!
It means that your engine coolant has overheated.
If you have been
operating your vehicle under normal driving conditions, you should pull
off
the road, stop your vehicle and turn off the engine as soon as possible.
If you have a digital cluster, a box around the temperature symbol will also
flash and a chime will sound when your engine is too hot.
Hot Coolant Can Burn you Badly! In Problems On The Road, this manual
explains what to do. See “Engine Overheating
” in the Index.

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 kdh) to reduce the possibility of engine and transmission overheating.
If you have an automatic transmission,
you should use “D” when towing a
trailer. Operating your vehicle in “D” when towing a trailer will minimize
heat buildup and extend the
life of your transmission. Or, if you have a
manual transmission with
fifth gear, it’s better not to use fifth gear, just
drive in fourth gear (or, as
you need to, a lower gear).
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 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 “P” (Park) yet, or into
gear for a manual transmission.
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.

Downloaded from www.Manualslib.com manuals search engine If the differential is cold, add enough lubricant to raise the level to 1/2 inch
(12 mm) below the filler plug hole.
What to use
Refer to the Maintenance Schedule to determine what kind of lubricant to
use.
See “Recommended Fluids and Lubricants” in the Index.
Engine Coolanr
The following explains your cooling system and how to add coolant when it
is
low. If you have a problem with engine overheating, see “Engine
Overheating” in the Index.
The proper coolant for your vehicle will:
0 Give freezing protection down to -20 “F (-29”C), or -34°F (-37°C) in
Give boiling protection up to 258°F (125°C).
Canada
and for
vehicles with the cold climate option.
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.
What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 6038-M,” which won’t damage
aluminum parts.
You can use a recycled coolant conforming to “GM
Specification 6038-M,” with a complete coolant flush and refill. If you use
this mixture, you don’t need to add anything else.

Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi (105 kPa) pressure-type cap and
must be tightly installed to prevent coolant
loss and possible
engine damage from overheating.
Be sure the arrows on the cap
line
up with the overflow tube on the radiator filler neck.
When you replace
your radiator pressure
cap, an
AP cap is
recommended. See
“Service Replacement
Part and Filter
Recommendations” in
the Index.
