Do not tow a trailer if your vehicle is equipped with a
2.2 L (VIN Code 4) engine.
Your car can tow
a trailer if it is equipped with the
3100 V6 (VIN Code M) engine and proper trailer towing
equipment, To identifj what the vehicle trailering capacity
is for your vehicle, you should read the information in
"Weight of the Trailer" that appears later in this section.
But trailering is different than just driving your vehicle by
itself. Trailering means changes in 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.
Load-pulling components such as the engine, transaxle,
wheel assemblies, and tires are forced to work harder
against
the
drag of
the
added weight. The engine is
required to operate at relatively higher speeds and under
greater loads, generating extra heat. What's more, the
trailer adds considerably to wind resistance, increasing
the pulling requirements.
If You Do Decide To Pull A Trailer
If you do, here are some important points.
0
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.
0
Consider using a sway control if your trailer will
weigh 2,000 pounds (900 kg) or less. You should
always use a sway control if your trailer will weigh
more than 2,000 pounds (900 kg).
Consider using a sway control.
You can ask a hitch dealer about sway controls.
0
Don't tow a trailer at all during the first I000 miles
( I 600 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
0
Then, during the frrst 500 miles (800
km)
that you tow
a trailer, don't drive over 50 mph (80 k m / h ) and don't
make starts at full throttle. This helps your engine and
other parts of your vehicle wear in at the heavier loads.
0
Obey speed limit restrictions when towing a trailer.
Don't drive faster than the maximum posted speed
for trailers (or no more than 55 mph (90 k d h ) ) to
save wear on your vehicle's parts.
