Towing a Trailer (Automatic
Transmission)
{WARNING:
The driver can lose control when pulling a trailer if
the correct equipment is not used or the vehicle is
not driven properly. For example, if the trailer is
too heavy, the brakes may not work well or even
at all. The driver and passengers could be
seriously injured. The vehicle may also be
damaged; the resulting repairs would not be
covered by the vehicle warranty. Pull a trailer only
if all the steps in this section have been followed.
Ask your dealer/retailer for advice and information
about towing a trailer with the vehicle. The vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment.
To identify the trailering capacity of the vehicle, read the
information in “Weight of the Trailer” that appears
later in this section.
Trailering is different than just driving the vehicle by
itself. Trailering means changes in handling,
acceleration, braking, durability and fuel economy.
Successful, safe trailering takes correct equipment, and
it has to be used properly.
The following information has 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
pulling a trailer.
Load-pulling components such as the engine,
transmission, rear axle, 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. The trailer also adds considerably to wind
resistance, increasing the pulling requirements.
5-33

Pulling A Trailer
Here are some important points:
•There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
the rig will be legal, not only where you live but
also where you will be driving. A good source for
this information can be state or provincial police.
•Do not tow a trailer at all during the first 1,000 miles
(1 600 km) the new vehicle is driven. The engine,
transmission or other parts could be damaged.
•Then, during the first 500 miles (800 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in at
the heavier loads.
•Vehicles can tow in D (Drive). Shift the transmission
to a lower gear if the transmission shifts too often
under heavy loads and/or hilly conditions.
•Obey speed limit restrictions when towing a trailer.
Do not drive faster than the maximum posted
speed for trailers, or no more than 55 mph
(90 km/h), to save wear on the vehicle’s parts.
•Do not tow when the outside air temperature is
above 100°F (38°C).
•Do not tow more than 1,000 miles (1 600 km)
per year.Three important considerations have to do with weight:
•The weight of the trailer
•The weight of the trailer tongue
•Weight on the vehicle’s tires
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs (450 kg). But
even that can be too heavy.
It depends on how the rig is used. For example, speed,
altitude, road grades, outside temperature and how
much the vehicle is used to pull a trailer are all
important. It can depend on any special equipment on
the vehicle, and the amount of tongue weight the vehicle
can carry. See “Weight of the Trailer Tongue” later in
this section for more information.
Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo in the tow vehicle
must be subtracted from the maximum trailer weight.
Ask your dealer/retailer for our trailering information or
advice. Also, see
Customer Assistance Offices on
page 8-6 for more information.
5-34

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total gross weight
of the vehicle. The Gross Vehicle Weight (GVW)
includes the curb weight of the vehicle, any cargo
carried in it, and the people who will be riding in the
vehicle. If there are a lot of options, equipment,
passengers or cargo in the vehicle, it will reduce the
tongue weight the vehicle can carry, which will also
reduce the trailer weight the vehicle can tow. If towing a
trailer, the tongue load must be added to the GVW
because the vehicle will be carrying that weight, too. See
Loading the Vehicle on page 5-24for more information
about the vehicle’s maximum load capacity. If using a weight-carrying hitch, the trailer tongue (A)
should weigh 10 to 15 percent of the total loaded trailer
weight (B).
After loading the trailer, weigh the trailer and then the
tongue, separately, to see if the weights are proper.
If they are not, adjustments might be made by moving
some items around in the trailer.
5-35

Total Weight on the Vehicle’s Tires
Be sure the vehicle’s tires are inflated to the upper limit
for cold tires. These numbers can be found on the
Certification label or seeLoading the Vehicle on
page 5-24 for more information. Make sure not to go over
the GVW limit for the vehicle, or the GAWR, including the
weight of the trailer tongue.
Hitches
It is important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are
a few reasons why the right hitch is needed.
•The rear bumper on the vehicle is not intended for
hitches. Do not attach rental hitches or other
bumper-type hitches to it. Use only a frame-mounted
hitch that does not attach to the bumper.
•Will any holes be made in the body of the vehicle
when the trailer hitch is installed? If so, be sure to
seal the holes when the hitch is removed. If they are
not sealed, deadly carbon monoxide (CO) from the
engine’s exhaust can get into the vehicle. See
Engine Exhaust on page 3-33 . Sealing the holes will
also prevent dirt and water from entering the vehicle.
Safety Chains
Always attach chains between the vehicle and the
trailer. Cross the safety chains under the tongue of the
trailer to help prevent the tongue from contacting
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 the rig can turn.
Never allow safety chains to drag on the ground.
Trailer Brakes
Does the trailer have its own brakes? Be sure to read
and follow the instructions for the trailer brakes so
they will be installed, adjusted and maintained properly.
Do not try to tap into the vehicle’s brake system. If
you do, both brake systems will not work well, or at all.
5-36

Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Get to know the rig before setting out for the open
road. Get acquainted 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
longer and not as responsive as the vehicle is by itself.
Before starting, check all trailer hitch parts and
attachments, safety chains, electrical connectors, lamps,
tires and mirror adjustments. If the trailer has electric
brakes, start the vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This checks the electrical
connection at the same time.
During the 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 the vehicle without a trailer. This
can help to avoid situations that require heavy braking
and sudden turns.
Passing
More passing distance is needed when towing a trailer.
Because the rig is longer, it is necessary to go much
farther beyond the passed vehicle before returning to
the lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, 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.
Making Turns
Notice:Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. The vehicle could be damaged. Avoid
making very sharp turns while trailering.
When turning with a trailer, make wider turns than
normal. Do this so the trailer will not strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.
5-37

Turn Signals When Towing a Trailer
The arrows on the instrument panel flash whenever
signaling a turn or lane change. Properly hooked up, the
trailer lamps also flash, telling other drivers the vehicle
is turning, changing lanes or stopping.
When towing a trailer, the arrows on the instrument
panel flash for turns even if the bulbs on the trailer are
burned out. For this reason you may think other
drivers are seeing the signal when they are not. It is
important to check occasionally to be sure the
trailer bulbs are still working.
Driving on Grades
Notice:Do not tow on steep continuous grades
exceeding 6 miles (9.6 km). Extended, higher
than normal engine and transmission temperatures
may result and damage the vehicle. Frequent
stops are very important to allow the engine and
transmission to cool.
Reduce speed and shift to a lower gear beforestarting
down a long or steep downgrade. If the transmission is
not shifted down, the brakes might have to be used so
much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce the
vehicle’s speed to around 45 mph (70 km/h) to reduce
the possibility of the engine and the transmission
overheating. Vehicles can tow in D (Drive). Shift the transmission to
a lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning to reduce
engine load. See
Engine Overheating on page 6-27 .
When towing under severe conditions such as hot
ambient temperatures or steep grades, the vehicle may
experience more transmission shifting. A COOLING
MODE ON message may also appear in the DIC. This
alerts the driver that the shifting mode is in progress
and is aiding engine cooling. See DIC Warnings
and Messages on page 4-38 DIC Warnings and
Messages for more information.Parking on Hills
{WARNING:
Parking the vehicle on a hill with the trailer
attached can be dangerous. If something goes
wrong, the rig could start to move. People can be
injured, and both the vehicle and the trailer can be
damaged. When possible, always park the rig on a
flat surface.
5-38

If parking the rig on a hill:1. Press the brake pedal, but do not shift into P (Park) yet for an automatic transmission, or into gear for a
manual transmission. Turn the wheels into the
curb if facing downhill or into traffic if facing uphill.
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 the parking brake, and then shift into P (Park) for an automatic
transmission or R (Reverse) for a manual
transmission.
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply the regular brakes and hold the pedal down while you:
•Start the engine.
•Shift into a gear.
•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
The vehicle needs service more often when pulling a
trailer. See Scheduled Maintenance on page 7-3
for more on this. Things that are especially important in
trailer operation are automatic transmission fluid (do
not overfill), engine oil, drive belt, cooling system
and brake system.
Each of these is covered in this manual, and the Index
will help to find them quickly. When trailering, it is a good
idea to review this information before starting the trip.
Check periodically to see that all hitch nuts and bolts are
tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat during
severe operating conditions. See Engine Overheating on
page 6-27.
Towing a Trailer (Manual
Transmission)
Do not tow a trailer if the vehicle is equipped with a
manual transmission.
5-39

If No Steam Is Coming From Your
Engine
An engine coolant temperature warning can indicate a
serious problem. SeeEngine Coolant Temperature
Warning Light on page 4-29 .
If you get an engine coolant temperature warning, but
see or hear no steam, the problem may not be too
serious. Sometimes the engine can get a little too hot
when you:
•Climb a long hill on a hot day.
•Stop after high-speed driving.
•Idle for long periods in traffic.
•Tow a trailer.
If you get the engine coolant temperature warning with
no sign of steam, try this for a minute or so: 1. If you have an air conditioner and it is on, turn it off.
2. In heavy traffic, let the engine idle in N (Neutral) for automatic transmission or NEUTRAL for manual
transmission, while stopped. If it is safe to do so, pull
off the road, shift to P (Park) or N (Neutral) and let
the engine idle.
3. Turn on your heater to full hot at the highest fan speed and open the windows as necessary. If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning does not come back on, you can drive
normally.
If the warning continues and you have not stopped, pull
over, stop, and park your vehicle right away.
If there is still no sign of steam, you can idle the engine
for three minutes while you are parked. If you still have
the warning, turn off the engine and get everyone out of
the vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
