Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
2,000 lbs (907 kg). But even
that can be too heavy.
It depends on how you plan to use
your rig. For example, speed,
altitude, road grades, outside
temperature and how much your
vehicle is used to pull a trailer are all
important. It can also depend on
any special equipment that you have
on your 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 form the
maximum trailer weight.You can ask your dealer/retailer for
our trailering information or
advice, or you can write us at our
Customer Assistance Offices.
SeeCustomer Assistance Offices
on page 12-4for more information.
Weight of the Trailer Tongue
The tongue load (A) of any trailer is
an important weight to measure
because it affects the total or gross
weight of your vehicle. The Gross
Vehicle Weight (GVW) includes the
curb weight of the vehicle, any
cargo you may carry in it, and the
people who will be riding in the
vehicle. If you have a lot of options,
equipment, passengers, or cargo
in your vehicle, it will reduce
the tongue weight your vehicle can
carry, which will also reduce the
trailer weight your vehicle can tow.
And if you tow a trailer, you
must add the tongue load to the
GVW because your vehicle will be
carrying that weight, too. SeeLoading the Vehicle on page 8-30
for more information about your
vehicle’s maximum load capacity.
If you are using a weight-carrying
hitch, the trailer tongue (A)
should weigh 10 to 15 percent of
the total loaded trailer weight (B).
After you have loaded your trailer,
weigh the trailer and then the tongue,
separately, to see if the weights are
proper. If they are not, you may be
able to get them right simply by
moving some items around in the
trailer.
Vehicle Service and Care 9-91

Driving with a Trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you will 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 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
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.
Towing with the Electronic
Stability Program (ESP®)
When towing, the sound of the ESP
modulator might be heard. The ESP
is reacting to the vehicle movement
caused by the trailer, which mainly
occurs during cornering. This is
normal when towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as when driving
your vehicle without a trailer. This
can help avoid situations that require
heavy braking and sudden turns.
Passing
More passing distance is needed up
ahead when you are towing a trailer.
And, because the vehicle 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, just move that
hand to the left. To move the trailer to
the right, move the 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 you are turning with a trailer,
make wider turns than normal. Do
this so your trailer will not strike soft
shoulders, curbs, road signs, trees or
other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.

Owner Checks and
Services
These owner checks and services
should be performed at the intervals
specied to help ensure vehicle
safety, dependability, and emission
control performance. Your dealer/
retailer can assist with these checks
and services.
Be sure any necessary repairs are
completed at once. Whenever
any uids or lubricants are added to
the vehicle, make sure they are
the proper ones, as shown in
Recommended Fluids and
Lubricants on page 11-12.
At Each Fuel Fill
It is important to perform these
underhood checks at each fuel fill.
Engine Oil Level Check
Notice:It is important to check
the engine oil regularly and keep it
at the proper level. Failure to keep
the engine oil at the proper level
can cause damage to the engine
not covered by the vehicle
warranty.
Check the engine oil level and
add the proper oil if necessary.
SeeEngine Oil on page 9-8.
Engine Coolant Level Check
Check the engine coolant level
and add DEX-COOL®coolant
mixture if necessary. SeeEngine
Coolant on page 9-15.
Windshield Washer Fluid
Level Check
Check the windshield washer uid
level in the windshield washer
uid reservoir and add the proper
uid if necessary.
At Least Once a Month
Tire Ination Check
Inspect the vehicle’s tires and make
sure they are inated to the correct
pressures. Do not forget to check
the spare tire, if the vehicle has one.
SeeInflation - Tire Pressure on
page 9-49. If the vehicle has a spare
tire, check to make sure it is stored
securely. SeeChanging a Flat Tire
on page 9-75.
Tire Wear Inspection
Tire rotation may be required for
high mileage highway drivers prior to
the Engine Oil Life System service
notication. Check the tires for
wear and, if necessary, rotate the
tires. SeeTire Inspection and
Rotation on page 9-57.
