Do you have the proper towing equipment?
See your dealer or trailering professional
for additional advice and equipment
recommendations.
Is your vehicle ready to be towed? Just as
you would prepare your vehicle for a long
trip, you’ll want to make sure your vehicle is
prepared to be towed. SeeBefore Leaving on
a Long Trip on page 346.
All-Wheel-Drive Vehicles
(TrailBlazer SS)
Notice:Towing an all-wheel-drive vehicle with
all four wheels on the ground, or even with
only two of its wheels on the ground, will
damage drivetrain components. Do not tow an
all-wheel-drive vehicle if any of its wheels
will be on the ground.
Your vehicle was not designed to be towed with
any of its wheels on the ground. If your vehicle
must be towed, see “Towing Your Vehicle” earlier
in this section.
Dinghy Towing
Two-Wheel-Drive Vehicles
Notice:If you tow your vehicle with all

If the suspension remains at a low height, the rear
axle load has exceeded GAWR (Gross Axle
Weight Rating). When the overload protection
mode is activated, the compressor operates
for about 30 seconds to one minute without raising
the vehicle depending on the amount of overload.
This will continue each time the ignition is
turned on until the rear axle load is reduced
below GAWR.
Indicator Light
The indicator light on the in ator switch in the rear
passenger compartment also serves as an
indicator for internal system error. If the indicator
light is ashing without the load leveling function
or the in ator being active, turn off the ignition. The
next day turn on the ignition and check the
indicator light. The vehicle can be driven with the
light ashing, but if it is you should have the
vehicle serviced as soon as possible.
Towing a Trailer
{CAUTION:
If you do not use the correct equipment
and drive properly, you can lose control
when you pull a trailer. For example, if the
trailer is too heavy, the brakes may not
work well — or even at all. You and your
passengers could be seriously injured. You
may also damage your vehicle; the
resulting repairs would not be covered by
your warranty. Pull a trailer only if you have
followed all the steps in this section. Ask
your dealer for advice and information
about towing a trailer with your vehicle.
368
Page 369 of 574

Notice:Pulling a trailer improperly can
damage your vehicle and result in costly repairs
that would not be covered by your warranty.
Always follow the instructions in this section
and check with your dealer/retailer for more
information about towing a trailer with your
vehicle.
To identify the trailering capacity of your vehicle,
you should read the information in “Weight of
the Trailer” that appears later in this section.
Trailering is different than just driving your vehicle
by itself. Trailering means changes in acceleration,
braking, handling, durability and fuel economy.
Successful, safe trailering takes correct equipment,
and it has to be used properly.
That’s the reason for this part. In it are many
time-tested, important trailering tips and safety
rules. Many of these are important for your safety
and that of your passengers. So please read
this section carefully before you pull a trailer.If You Do Decide To Pull A Trailer
If you do, here are some important points:
There are many different laws, including speed
limit restrictions, having to do with trailering.
Make sure your rig will be legal, not only where
you live but also where you’ll be driving. A
good source for this information can be state
or provincial police.
Consider using a sway control. See “Hitches”
later in this section.
Don’t tow a trailer at all during the rst
500 miles (800 km) your new vehicle is driven.
Your engine, axle or other parts could be
damaged.

Trailer Brakes
If your trailer weighs more than 1,500 lbs (680 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 install, adjust and maintain them properly.
Your trailer’s brake system can tap into the
vehicle’s hydraulic brake system only if:
The trailer parts can withstand 3,000 psi
(20 650 kPa) of pressure.
The trailer’s brake system will use less than
0.02 cubic inch (0.3 cc) of uid from your
vehicle’s master cylinder. Otherwise,
both braking systems won’t work well. You
could even lose your brakes.
If everything checks out this far, then make the
brake uid tap at the port on the master cylinder
that sends uid to the rear brakes. But don’t
use copper tubing for this. If you do, it will bend
and nally break off. Use steel brake tubing.
Driving with a Trailer
{CAUTION:
If you have a rear-most window open and
you pull a trailer with your vehicle, carbon
monoxide (CO) could come into your
vehicle. You can not see or smell CO. It
can cause unconsciousness or death. See
Engine Exhaust on page 130. To maximize
your safety when towing a trailer:
Have your exhaust system inspected
for leaks and make necessary repairs
before starting on your trip.
Keep the rear-most windows closed.
If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with
the fan on any speed. This will bring
fresh, outside air into your vehicle.
CAUTION: (Continued)

CAUTION: (Continued)
Do not use the climate control setting
for maximum air because it only
recirculates the air inside your vehicle.
SeeDual Climate Control System on
page 187orDual Automatic Climate
Control System on page 190.
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 all trailer hitch parts and
attachments, safety chains, electrical connection,
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 the 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.Following Distance
Stay at least twice as far behind the vehicle ahead
as you would when driving your vehicle without
a trailer. This can help you avoid situations
that require heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a
good deal longer, you’ll need to go much farther
beyond the passed vehicle before you can
return to your lane.
Backing Up
Hold the bottom of the steering wheel with
one hand. Then, to move the trailer to the left, just
move that hand to the left. To move the trailer
to the right, move your hand to the right. Always
back up slowly and, if possible, have someone
guide you.
