Tire and Loading Information
Label
A vehicle specic Tire and
Loading Information label is
attached to the center pillar
(B-pillar) of your vehicle. With
the driver’s door open, you
will nd the label attached below
the door lock post (striker).The tire and loading information
label shows the number of
occupant seating positions (A),
and the maximum vehicle
capacity weight (B) in kilograms
and pounds.
The Tire and Loading Information
label also shows the size of the
original equipment tires (C) and
the recommended cold tire
ination pressures (D). For more
information on tires and ination
seeTires on page 5-36and
Inflation - Tire Pressure on
page 5-42.
There is also important loading
information on the vehicle
Certication/Tire label. It tells
you the Gross Vehicle Weight
Rating (GVWR) and the
Gross Axle Weight Rating
(GAWR) for the front and rear
axle. See “Certication/Tire
Label” later in this section.
Steps for Determining Correct
Load Limit
1.
Locate the statement “The
combined weight of
occupants and cargo should
never exceed XXX kg or
XXX lbs” on your vehicle’s
placard.
2.Determine the combined
weight of the driver and
passengers that will be riding
in your vehicle.
3.Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lbs.
4.The resulting gure equals
the available amount of
cargo and luggage load
capacity. For example, if the
“XXX” amount equals
1400 lbs and there will be
ve 150 lb passengers in your
vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs
(1400−750 (5 x 150) = 650 lbs).
Example Label
Driving Your Vehicle 4-17

For vehicles being dinghy towed,
the vehicle should be run at
the beginning of each day and at
each RV fuel stop for about
ve minutes. This will ensure proper
lubrication of transmission
components. Re-install the fuse to
start the vehicle.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle to tow and
then secure it to the towing
vehicle.
2. Shift the transmission to P (Park)
and turn the ignition to
LOCK/OFF.
3. Set the parking brake.
4. Turn the ignition to
ACC/ACCESSORY.
5. Shift the transmission to
N (Neutral).6. To prevent the battery from
draining while the vehicle is being
towed, remove the 50 amp
BATT1 fuse from the underhood
fuse block and store in a safe
location. SeeUnderhood
Fuse Block on page 5-94.
7. Release the parking brake.
Notice:If the vehicle is towed
without performing each of
the steps listed under “Dinghy
Towing,” the automatic
transmission could be damaged.
Be sure to follow all steps of
the dinghy towing procedure prior
to and after towing the vehicle.
Notice:If 65 mph (105 km/h)
is exceeded while towing
the vehicle, it could be damaged.
Never exceed 65 mph (105 km/h)
while towing the vehicle.Once the destination is reached:
1. Set the parking brake.
2. Reinstall the 50 amp BATT1 fuse
to the underhood fuse block.
3. Shift the transmission to P (Park),
turn the ignition to LOCK/OFF
and remove the key from
the ignition.
4. Disconnect the vehicle from the
towing vehicle.
Notice:Do not tow a vehicle
with the front drive wheels on the
ground if one of the front tires
is a compact spare tire. Towing
with two different tire sizes on the
front of the vehicle can cause
severe damage to the
transmission.

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 the safety of the
driver and the 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. What’s more, the trailer
adds considerably to wind
resistance, increasing the pulling
requirements.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.
Consider using a sway control.
See “Hitches” later in this
section.
Do not tow a trailer at all during
the rst 500 miles (800 km) the
new vehicle is driven. The engine,
axle or other parts could be
damaged.
Driving Your Vehicle 4-25

Then, during the rst 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.
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.
The 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. See “Tow/Haul
Mode” later in this section.
The vehicle is designed primarily
as a passenger and load carrying
vehicle. If a trailer is towed,
the vehicle will require more
frequent maintenance due to the
additional load.Three important considerations have
to do with weight:
The weight of the trailer.
The weight of the trailer tongue.
And the weight on the vehicle’s
tires
Weight of the Trailer
How heavy can a trailer safely be?
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.
Use the following chart to determine
how much the vehicle can weigh,
based upon the vehicle model
and options.
4-26 Driving Your Vehicle

If the vehicle has many options and
there is a front seat passenger and
two rear seat passengers with some
luggage and gear in the vehicle as
well. 300 lbs (136 kg) could be
added to the front axle weight and
400 lbs (181 kg) to the rear axle
weight. The vehicle now weighs:
Weight is still below 7,200 lbs
(3 266 kg) and you might think
700 additional pounds (318 kg)
should be subtracted from the
trailering capacity to stay within
GCWR limits. The maximum trailer
would only be 7,800 lbs (3 538 kg).
You may go further and think the
tongue weight should be limited to
less than 1,000 lbs (454 kg) to avoid
exceeding GVWR. But the effect on
the rear axle must still be considered.
Because the rear axle now weighs3,100 lbs (1 406 kg), 900 lbs
(408 kg) can be put 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
only 600 lbs (272 kg) of tongue
weight that can be handled. Since
tongue weight is usually at least
10 percent of total loaded trailer
weight, expect that the largest trailer
the vehicle can properly handle is
6,000 lbs (2 721 kg).
It is important that the vehicle
does not exceed any of its
ratings — GCWR, GVWR, RGAWR,
Maximum Trailer Rating or Tongue
Weight. The only way to be sure it is
not exceeding any of these ratings is
to weigh the vehicle and trailer.
Total Weight on the Vehicle’s
Tires
Be sure the vehicle’s tires are
inated to the upper limit for cold
tires. These numbers can be found
on the Certication/Tire label.
SeeLoading the Vehicle onpage 4-16. Make sure not to go
over the GVW limit for the 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
the right hitch is needed. Here are
some rules to follow:
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 there
are, then be sure to seal the holes
later when the hitch is removed.
If the holes are not sealed, dirt,
water, and deadly carbon
monoxide (CO) from the exhaust
can get into the vehicle. See
Engine Exhaust on page 2-30.
Driving Your Vehicle 4-29

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
A loaded trailer that weighs more
than 1,000 lbs (450 kg) needs
to have its own brake system that is
adequate for the weight of the
trailer. Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted
and maintained properly.Because the vehicle has antilock
brakes, do not try to tap into
the vehicle’s hydraulic brake system.
If you do, both brake systems will
not work well, or at all.
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.
