Certification Label
52D059
A vehicle specific Certification/Tire label is
found on the rear edge of the driver’s door.
The label shows the size of your original
tires and the inflation pressures needed to
obtain 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 occu-
pants, fuel, and cargo.
The Certification/Tire label also tells you
the maximum weights for the front and rear
axles, called the Gross Axle Weight Rating
(GAWR). To find out the actual loads on
your front and rear axles, you need to go to
a weigh station and weigh your vehicle.
Your dealer 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.
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.
WARNING
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.
WARNING
Overloading your vehicle may cause
damage. Repairs would not be cov-
ered by your warranty. Do not over-
load your vehicle.
WARNING
Things you put inside your vehicle
can strike and injure people in a sud-
den 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.

the ground. It can be towed with car carrier
equipment.Level ControlYour vehicle may have this feature. This
self-adjusting type of level control is fully
automatic and will provide a better leveled
riding position as well as better handling
under a variety of passenger and loading
conditions. The system is activated when
sufficient weight is added to the vehicle,
and will automatically adjust vehicle height
thereafter. A hydraulic pump inside each
rear shock absorber raises the rear of the
vehicle to the proper height, based on
inputs from the road surface, while the
vehicle is being driven. It takes approxi-
mately two miles (3.2 km) of driving for the
leveling to complete, depending on the
road surface conditions.
If the loaded vehicle is not moved for
approximately twelve hours, the leveling
system may bleed down to a lower height.
This can be especially apparent if a trailer
is left attached to a parked vehicle for long
periods of time. The vehicle must be driven
to re-level the vehicle. If a self-equalizing
hitch is being used, the vehicle should be
driven approximately two miles (3.2 km)
with the trailer prior to adjusting (leveling)
the hitch.
Towing a TrailerTo 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. Suc-cessful, safe trailering takes correct equip-
ment, and it has to be used properly.
That is the reason for this section. In it are
many time-tested, important trailering tips
and safety rules. Many of these are impor-
tant for your safety and that of your pas-
sengers. 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 will be driving. A good source
for this information can be state or pro-
vincial police.
Consider using a sway control. Refer to
“Hitches” later in this section.
Do not tow a trailer at all during the first
500 miles (800 km) your new vehicle is
driven. Your engine, axle or other parts
could be damaged.
During the first 500 miles (800 km) that
you tow a trailer, do not drive over 50
mph (80 km/h) and do not make starts at
full throttle. This helps your engine and
other parts of your vehicle wear in at the
heavier loads.
WARNING
If you do not use the correct equip-
ment 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. 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 vehi-
cle.
CAUTION
Pulling a trailer improperly can dam-
age 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 for more information
about towing a trailer with your vehi-
cle.

4-22 DRIVING YOUR VEHICLE
78J00-03E
Three important considerations have to do
with weight:
Weight of the trailer
Weight of the trailer tongue
Weight on your vehicle’s tires
Weight of the Trailer
How heavy can a trailer safely be?
Your vehicle can tow up to 2,900 lbs (1300
kg) with up to five occupants or up to 3,500
lbs (1575 kg) with up to two occupants. 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 pull a trailer are all impor-
tant. It can also depend on any special
equipment that you have on your vehicle,
and the amount of tongue weight vehicle
can carry. Refer to “Weight of the Trailer
Tongue” later in this section for more infor-
mation.
Maximum trailer weight is calculated
assuming only the driver is in the tow vehi-
cle 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.
You can ask your dealer for our trailering
information or advice, or you can write us
at our Customer Assistance Offices.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, passengers, or cargo in
the 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 will tow a trailer, you must
add the tongue load to the GVW because
your vehicle will be carrying that weight,
too. Refer to “Loading Your Vehicle” in this
section for more information about your
vehicle’s maximum load capacity.
806596
If you are using a weight-carrying or a
weight-distributing hitch, the trailer tongue
weight (A) should be 10 percent to 15 per-cent of the total loaded trailer weight (B).
Do not exceed the maximum allowable
tongue weight for your vehicle (400 lbs/181
kg).
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 sim-
ply by moving some items around in the
trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to
the upper limit for cold tires. You will find
these numbers on the Certification/Tire
Label at the rear edge of the driver’s door,
or refer to “Loading Your Vehicle” in this
section. Then be sure you do not go over
the GVW limit for your vehicle, 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
you will need the right hitch. Here are
some rules to follow:
If you will be pulling a trailer that, when
loaded, will weigh more than 2000 lbs
(900 kg), be sure to use a properly
mounted, weight-carrying hitch and sway
control of the proper size. This equip-
ment is very important for proper vehicle
loading and good handling when you’re
driving.

4-24 DRIVING YOUR VEHICLE

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, elec-
trical connector, lamps, tires and mirror
adjustment. If the trailer has electric
brakes, start your vehicle and trailer mov-
ing and then apply the trailer brake control-
ler 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 work-
ing.
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 will need more passing distance up
ahead when you are towing a trailer. And,
because you are a good deal longer, you
will 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.
Making Turns
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.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to
have extra wiring.
The arrows on your instrument panel will
flash whenever you signal a turn or lane
change. Properly hooked up, the trailer
lamps will also flash, telling other drivers
you are about to turn, change lanes or
stop.When towing a trailer, the arrows on your
instrument panel will flash for turns even if
the bulbs on the trailer are burned out.
Thus, you may think drivers behind you are
seeing your signal when they are not. It’s
important to check occasionally to be sure
the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you do not shift down, you
might have to use your brakes so much
that they would get hot and no longer work
well.
Parking on Hills
But if you ever have to park your rig on a
hill, do the following:
1) Apply your regular brakes, but do not
shift into PARK (P) yet.
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.
CAUTION
Making very sharp turns while traile-
ring could cause the trailer to come
in contact with the vehicle. Your vehi-
cle could be damaged. Avoid making
very sharp turns while trailering.
WARNING
You really should not park your vehi-
cle, with a trailer attached, on a hill. If
something goes wrong, your rig
could start to move. People can be
injured, and both your vehicle and
the trailer can be damaged.

Vehicle Placard:
A label permanently attached to a vehicle
showing the vehicle’s capacity weight and
the original equipment tire size and recom-
mended inflation pressure. Refer to “Tire
and Loading Information Label” under
“Loading Your Vehicle” in “Your Driving,
the Road, and Your Vehicle” in the “Driving
Your Vehicle” section.Inflation – Tire PressureTires need the correct amount of air pres-
sure to operate effectively.
A Tire and Loading Information label is
attached to the vehicle’s center pillar (B-
pillar). This label shows your vehicle’s orig-
inal equipment tires and the correct infla-
tion pressures for your tires when they are
cold. The recommended cold tire inflation
pressure, shown on the label, is the mini-
mum amount of air pressure needed to
support your vehicle’s maximum load car-
rying capacity.
For additional information regarding how
much weight your vehicle can carry, and
an example of the Tire and Loading Infor-
mation label, refer to “Loading Your Vehi-cle” in “Your Driving, the Road, and Your
Vehicle” in the “Driving Your Vehicle” sec-
tion. How you load your vehicle affects
vehicle handling and ride comfort. Never
load your vehicle with more weight than it
was designed to carry.
When to Check
Check your tires once a month or more. Do
not forget to check the compact spare tire,
it should be at 60 psi (420 kPa). For addi-
tional information regarding the compact
spare tire, refer to “Compact Spare Tire” in
this section.
How to Check
Use a good quality pocket-type gage to
check tire pressure. You cannot tell if your
tires are properly inflated simply by looking
at them. Radial tires may look properly
inflated even when they are under-inflated.
Check the tire’s inflation pressure when
the tires are cold. Cold means your vehicle
has been sitting for at least three hours or
driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve
stem. Press the tire gage firmly onto the
valve to get a pressure measurement. If
the cold tire inflation pressure matches the
recommended pressure on the Tire and
Loading Information label, no further
adjustment is necessary. If the inflation
pressure is low, add air until you reach the
recommended amount.
CAUTION
Do not let anyone tell you that under-
inflation or over-inflation is all right. It
is not. If your tires do not have
enough air (under-inflation), you can
get the following:
Too much flexing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-
inflation), you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road haz-
ards
