Here’s an alphabetical listing of almost every subject in this
manual. You can use it to quickly find something you want
to read.

If your vehicle has
four-wheel anti-lock
brakes, it will have
this yellow light.
3
With anti-lock, this light will go on when you start your engine and may
stay on for several seconds. That’s normal. If the light doesn’t come \
on,
have it fixed
so it will be ready to warn you if there is a problem.
If the light stays on, or comes on when you’re driving, your vehic\
le needs
service.
If the regular brake system warning light isn’t on, you still \
have
brakes, but you don’t have anti-lock brakes.
If the regular brake system
warning light is also on, you don’t have anti-lock brakes and there’s a
problem with your regular brakes. See “Brake System Warning Light”
earlier in this part.
Engine Coolant Temperature Gage
I 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 shou\
ld pull
off
the road, stop your vehicle and turn off the engine as soon as possible.
Hot Coolant Can Burn you Badly! In Problems On The Road, this manual
explains what
to do. See “Engine Overheating ’’ in the Index.

Reduce speed and shift to a lower gear before you start dawn 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) 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
rrianual 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
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
gear
for
a manual transmission.
chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking brake, and \
then
shift into
“P” (Park), or “R” (Reverse) for a manual transmission.
5. If you have a four-wheel drive vehicle with a manual transfer \
case shift
lever, be sure the transfer case is
in a drive gear-not in “N” (Neutral).
6. Release the parking brakes,

You will find a coolant temperature gage on your vehicle’s instr\
ument
panel.
If Steam Is Coming From Your Engine
NOTICE:
If your engine catches fire because you keep driving with no
coolant, your vehicle cdh be badly damaged. The costly repairs
would not be covered by your warranty.

Downloaded from www.Manualslib.com manuals search engine If the differential is at operating temperature (w,arm), add enou\
gh lubricant
to raise the level to the bottom of the filler plug hole.
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 Coolant
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:
Give freezing protection down to -20 “F (-29” C), or -34°F (-37 “C) in
Canada and for vehicles with the cold climate option.
e Give boiling protection up to 258°F (125°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
What to Use
Use a mi,xture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 603%” or “GM Specification
6043-M ”for the 2.2L (LN2) Code 4 engine, which won’t damage
aluminum parts. You can also use
a recycled coolant conforming to “GM
Specification 603%” or “GM Specification 6043-M ”for the 2.2L (LN2)
Code 4 engine with a complete coolant flush and refill.
If you use this
mixture, you don’t need to add anything else.

Radiator Pressure Cap
I 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, a
GM cap is
recommended. See
“Service Replacement
Part and Filter
Recommendations” in
the Index.
