Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you’re
going fast enough. When your vehicle is hydroplaning,
it has little or
no contact with the road.
Hydroplaning doesn’t happen often. But it can if your
tires haven’t much tread or if the pressure
in one or
more is low. It can happen if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles, or other vehicles, and raindrops “dimple” the
water’s surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t
a hard and fast rule about hydroplaning. The
best advice is to slow down when it
is raining.
Some Other Rainy Weather Tips
0 Turn on your low-beam headlamps -- not just your . -,
parking lights -- to help make you more visible to
others.
Besides slowing down, allow-some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room
, .
ahead, and be prepared to have your view restricted .
by road spray.
Have good tires with proper tread depth. (See
“Tires” in the Index.)

Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer
so that the tongue will not drop to the road
if it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow the
manufacturer’s recommendation for attaching safety
chains and do not attach them to the bumper. Always
leave just enough slack
so you can turn with your rig.
And, never .allow safety chains to drag on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 pounds (450 kg)
loaded, then it needs its own brakes
-- and they must be
adequate. Be sure
to read and follow the instructions for
the trailer brakes
so you’ll be able to instal, adjust and
maintain them properly. Because you have anti-lock
brakes, do not try to tap into your vehicle’s brake
system. If you do, both brake systems won’t work well,
or at all.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel
of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand.to be sure
thg brakes
are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.

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
PARK (P) 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.
4. Reapply the regular brakes, Then apply your parking
brake, and then shift to PARK (P), or REVERSE (R)
for a manual transmission.
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;
0 Shift into a gear; and
0 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’re
pulling a trailer. See the Maintenance Schedule for more on this. Things that
are especially important in trailer
operation
are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belts, cooling
system, and brake adjustment. Each
of these is covered
in this manual, and the Index will help you find them
quickly.
If you’re trailering, it’s a good idea to review
these sections before you start your trip.
Check periodically to see that all hitch nuts and bolts are
tight.

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, 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.

Gasolines for Cleaner Air
Your use of gasoline with deposit control additives will
help prevent deposits from forming in your engine and
fuel system. That helps keep your engine in tune and
your emission control system working properly. It’s
good for your vehicle, and you’ll be doing your part for
cleaner air.
Many gasolines are now blended with oxygenates. General Motors recommends that you use gasolines with
these blending materials, such as MTBE and ethanol. By doing
so, you can help clean the air, especially in those
parts of the country that have high carbon monoxide
levels.
In addition, some gasoline suppliers are now producing
reformulated gasolines. These gasolines
are specially
designed to reduce vehicle emissions. General Motors
recommends that you use reformulated gasoline. By doing
so, you can help clean the air, especially in those
parts
of the country that have high ozone levels.
You should ask your service station operators if their
gasolines contain deposit control additives and
oxygenates, and if they have been reformulated to
reduce vehicle emissions.
Fuels in Foreign Countries
If you plan on driving in another country outside the
U.S. or Canada, unleaded fuel may be hard to find. Do
not use leaded gasoline. If you use even one tankful,
your emission controls won’t work
well or at all. With
continuous use, spark plugs can get fouled, the exhaust
system can corrode, and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor will be damaged.
All of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell us where you’re going and give your

Wait at least 30 minutes before checking the
transmission fluid level if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180" F to 200" F
(82°C to 93°C).
To check transmission fluid hot: Get the vehicle
warmed up by driving about
15 miles (24 km) when
outside temperatures
&e above 50°F (10°C).
If its colder than 50" F (10" C) drive the vehicle in
DRIVE (D) until the engine temperature gage moves
and then remians steady for ten minutes. Then
follow
the hot check procedures.
To check transmission fluid cold: A cold check is
made after the vehicle has been sitting for eight hours or
more with the engine
off and is used only as a reference.
Let the engine run at idle for five minutes if outside
temperatures are
50°F (10°C) or more. If it's colder
than 50°F (lO"C), you may have to idle the engine
longer. Should the fluid level be low during a cold
check, you
must perform a hot check before adding
fluid. This will give you
a more accurate reading of the
fluid level.
To check the fluid hot or cold:
Park your vehicle on a level place. Keep the engine
With the parking brake applied, place the shift lever
running.
in PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in'each range. Then, position the shift
lever in PARK
(P).
Let the engine run at idle for three minutes or more.

3.8L Transmission Dipstick
4. If the fluid level is in the acceptable range, push the
dipstick back . .. in all the way.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. See “Recommended
Fluids and Lubricants”
in the Index.
Add fluid only after checking the transmission fluid
HOT. (A COLD check is used only as a reference.)
If
the fluid level is low, add only .enough of the proper
fluid to bring the level up
to the HOT area for a hot
check. It doesn’t take much fluid, generally less than a
pint.
Don ’t oveflill. We recommend you use only fluid
labeled DEXRON@-III, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON@-111 is
not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way.

Inflation - Tire Pressure
The Tire-Loading Information label which is on the
driver’s door shows the correct inflation pressures for
your tires, when they’re cold. “Cold” means your
vehicle has been sitting for at least three hours or driven no more than a mile.
If you’ll be driving at speeds higher than 100 mph (160 km/h)
where it is legal, raise the “cold” inflation pressure of\
each
tire to 35 psi (240 k Pa). When you end this very high speed
driving, reduce the “cold” inflation pressures to those
listed
on the tire loading information label.
Don’t let anyone tell you that underinnation or
overinflation
is all right. It’s not. If’ your tires don’t
have enough
air (underinflation) you can get:
Too much flexing
Too much heat
Tire overloading
Bad wear
0 Bad handling
Bad fuel economy.
(Continued)
NOTICE: (Continued)
If your tires have too much air (overinflation),
you can get:
Unusual wear
Bad handling
Rough ride
0 Needless damage from road hazards.
. ., .. ,
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. Simply looking at the tires will not tell you the
pressure, especially if you have radial tires
-- which
may look properly inflated even
if they’re underinflated.
If your tires have valve caps, be sure to put them back
on. They help prevent leaks by keeping ou,t dirt and
moisture.
