How to Add Coolant to the Radiator
1. You can remove the radiator pressure cap when the
cooling system, including the radiator pressure cap and
upper radiator hose. is no longer hot. Turn the pressure
cap slowly counterclockwise
until it first stops. (Don’t
press down while turning
the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.
2. Then keep turning the pressure cap, but now push
down as you
turn it. Remove the pressure cap.

If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly.
If air goes
out
of a tire, it’s much more likely to leak out slowly.
But if
you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If
a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel
firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a
stop -- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a
flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
ur
Changing a tire can cause an injury. The vehicle
can slip
off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to change your tire.
To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire
on the other side of the
vehicle, at the opposite end.

The spare tire is stowed under the vehicle.
I NOTICE:
Never remove or restow a tire frondto a stowage
position under the vehicle while the vehicle
is
supported by a jack. Always tighten the tire
fully against the underside of the vehicle when restawing.
To remove the spare, insert
the chisel end
of the wheel
wrench, on an angle, into
the hole in the rear bumper.
Be sure the chisel end of the
wheel wrench connects into
the hoist shaft. Turn the wheel wrench
counterclockwise to lower the
spare tire. Keep turning the wheel wrench
until the spare
tire can be pulled out
from under the vehicle.
When the tire has been completely lowered, tilt the
retainer at the end
of the cable and pull it through the
wheel opening. Pull the tire out from under the vehicle.
NOTICE:
To help avoid vehicle damage, do not drive the
vehicle before the cable
is restored.
Put the spare tire near the flat tire.

off. This could lead to an accident.
Be sure to use the correct wheel nuts.
If you have
to replace them, be sure to get new
GM original
equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to
