Refer to your vehicle’s tire and loading information
label for specic information about your vehicle’s
capacity weight and seating positions.
The combined weight of the driver, passengers
and cargo should never exceed your vehicle’s
maximum vehicle capacity weight.
Certication/Tire Label
A vehicle specic Certication/Tire label is
attached to the rear edge of the driver’s door.
The label shows the gross weight capacity of your
vehicle. This is called the Gross Vehicle Weight
Rating (GVWR). The GVWR includes the weight of
the vehicle, all occupants, fuel, cargo, and trailer
tongue weight, if your vehicle is pulling a trailer.
Example 3

The Certication/Tire label also tells you the
maximum weights for the front and rear axles,
called Gross Axle Weight Rating (GAWR).
To nd out the actual loads on your front and rear
axles, you need to go to a weigh station and
weigh your vehicle. Your retailer can help you with
this. Be sure to spread out your load equally on
both sides of the centerline.
Never exceed the GVWR for your vehicle, or the
GAWR for either the front or rear axle.
Similar looking vehicles may have different
GVWRs and payloads. Please consult your
vehicle’s Certication/Tire label or your retailer
for additional details.
{CAUTION:
Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do,
parts on your vehicle can break, and it
can change the way your vehicle handles.
These could cause you to lose control
and crash. Also, overloading can shorten
the life of your vehicle.
Using heavier suspension components to get
added durability might not change your vehicle’s
weight ratings. Ask your retailer to help you
load your vehicle correctly if you are using these
components.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.

If you put things inside your vehicle — like
suitcases, tools, packages, or anything else — they
will go as fast as the vehicle goes. If you have to
stop or turn quickly, or if there is a crash, they will
keep going.
{CAUTION:
Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the cargo area of your
vehicle. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
Do not leave an unsecured child
restraint in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down
unless you need to.

Towing Your Vehicle
Consult your retailer or a professional towing
service if you need to have your disabled vehicle
towed. SeeRoadside Assistance Program on
page 445.
If you want to tow your vehicle behind another
vehicle for recreational purposes (such as
behind a motorhome), see “Recreational Vehicle
Towing” following.

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/retailer for advice and
information about towing a trailer with
your vehicle.
Notice:Pulling a trailer improperly can
damage your vehicle and result in costly repairs
not covered by your warranty. To pull a trailer
correctly, follow the advice in this part and see
your dealer/retailer for important information
about towing a trailer with your vehicle.Your vehicle can tow a trailer if it is equipped with
the proper trailer towing equipment. 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 handling,
acceleration, braking, 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,
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. 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:
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 (805 km) your new vehicle is driven.
Your engine, axle or other parts could be
damaged. The repairs would not be covered
by your warranty.
Then, during the rst 500 miles (805 km) that
you tow a trailer, don’t drive over 50 mph
(80 km/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.
If you have an automatic transmission, you can
use INTERMEDIATE (I) or as you need to, a
lower gear which will minimize heat buildup and
extend the life of your transmission.
If you have a manual transmission, you should
not use FIFTH (5) gear. Drive in FOURTH (4)
gear or as you need to a lower gear.
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 km/h), to save wear on your
vehicle’s parts.
Don’t tow a trailer when the outside
temperature is above 100°F (38°C).
Three important considerations have to do
with weight:
the weight of the trailer
the weight of the trailer tongue
and the total weight on your vehicle’s tires

ProCarManuals.com

Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,500 lbs
(680 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 must be subtracted from the maximum
trailer weight.
You can ask your retailer for trailering information
or advice.
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 Your
Vehicle on page 279for more information about
your vehicle’s maximum load capacity.
292
ProCarManuals.com

If you’re using a weight-carrying hitch, the trailer
tongue (A) should weigh 10 percent of the
total loaded trailer weight (B). If you’re using a
weight-distributing hitch, the trailer tongue (A)
should weigh 12 percent of the total loaded trailer
weight (B).
After you’ve loaded your trailer, weigh the trailer
and then the tongue, separately, to see if the
weights are proper. If they aren’t, you may be able
to get them right simply by moving some items
around in the trailer.Trailering may be limited by the vehicle’s ability
to carry tongue weight. Tongue weight cannot
cause the vehicle to exceed the GVWR
(Gross Vehicle Weight Rating) or the RGAWR
(Rear Gross Axle Weight Rating). The effect
of additional weight may reduce your trailering
capacity more than the total of the additional
weight.
Consider the following example:
A vehicle model base weight is 5,500 lbs
(2 495 kg); 2,800 lbs (1 270 kg) at the front
axle and 2,700 lbs (1 225 kg) at the rear axle.
It has a GVWR of 7,200 lbs (3 266 kg),
a RGAWR of 4,000 lbs (1 814 kg) and a
GCWR (Gross Combination Weight Rating)
of 14,000 lbs (6 350 kg).
293
ProCarManuals.com

The trailer rating should be:
You can expect tongue weight to be at least
10 percent of trailer weight (850 lbs (386 kg)) and
because the weight is applied well behind the
rear axle, the effect on the rear axle will be greater
than just the weight itself, as much as 1.5 times
as much. The weight at the rear axle could
be 850 lbs (386 kg) X 1.5 = 1,275 lbs (578 kg).
Since the rear axle already weighs 2,700 lbs
(1 225 kg), adding 1,275 lbs (578 kg) brings the
total to 3,975 lbs (1 803 kg). This is very close to,
but within the limit for RGAWR as well. The
vehicle is set to trailer up to 8,500 lbs (3 856 kg).
But let’s say your specic vehicle is equipped with
some of the latest options and you have a front seat
passenger and two rear seat passengers with
some luggage and gear in the vehicle as well.You may add 300 lbs (136 kg) to the front axle
weight and 400 lbs (181 kg) to the rear axle weight.
Your vehicle now weighs:
Weight is still below 7,200 lbs (3 266 kg) and you
may think that you should subtract 700 additional
pounds (318 kg) from your trailering capacity
to stay within GCWR limits. Your maximum trailer
would only be 7,800 lbs (3 538 kg). You may
go further and think you must limit tongue weight
to less than 1,000 lbs (454 kg) to avoid exceeding
GVWR. But, you must still consider the effect
on the rear axle. Because your rear axle now
weighs 3,100 lbs (1 406 kg), you can only
put 900 lbs (408 kg) on the rear axle without
exceeding RGAWR. The effect of tongue weight is
about 1.5 times the actual weight. Dividing the
900 lbs (408 kg) by 1.5 leaves you with being able
to handle only 600 lbs (272 kg) of tongue weight.
294
ProCarManuals.com

Since tongue weight is usually at least 10 percent
of total loaded trailer weight, you can expect
that the largest trailer your vehicle can properly
handle is 6,000 lbs (2 721 kg).
It is important that you make sure your vehicle
does not exceed any of its ratings — GCWR,
GVWR, RGAWR, Maximum Trailer Rating
or Tongue Weight. The only way to be sure you
are not exceeding any of these ratings is to weigh
your vehicle and trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inated to the
upper limit for cold tires. You will nd these
numbers on the Tire and Loading Information
label. SeeLoading Your Vehicle on page 279.
Then be sure you don’t go over the GVW limit for
your vehicle or the Gross Axle Weight Rating
(GAWR), including the weight of the trailer tongue.
Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough
roads are a few reasons why you will need the
right hitch. Here are some rules to follow:
The rear bumper on your 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 you have to make any holes in the body
of your vehicle when you install a trailer
hitch? If you do, then be sure to seal the holes
later when you remove the hitch. If you don’t
seal them, deadly carbon monoxide (CO)
from your exhaust can get into your vehicle.
SeeEngine Exhaust on page 123. Dirt and
water can, too.

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 vehicle has anti-lock brakes, don’t try to
tap into your vehicle’s hydraulic brake system.
If you do, both brake systems won’t work well,
or at all.
Be sure to read and follow the instructions for the
trailer brakes, so you’ll be able to install, adjust
and maintain them properly.
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 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.
