VEHICLE LOAD LIMIT
Tire and loading information
label
The label located on the driver's door
sill gives the original tire size, cold
tire pressures recommended for your
vehicle, the number of people that
can be in your vehicle and vehicle
capacity weight.
Steps for determining correct
load limit
1. Locate the statement "The com-
bined 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 figure equals the
available amount of cargo and lug-
gage load capacity. For example, if
the "XXX" amount equals 635 kg
(1400 lbs.), and there will be five
68 kg (150 lbs.) passengers in
your vehicle, the amount of avail-
able cargo and luggage load
capacity is 295 kg (650 lbs.).
(635-340 (5 x 68) = 295 kg or
1400-750 (5 x 150) = 650 lbs.)5. Determine the combined weight of
luggage and cargo being loaded
on the vehicle. That weight may
not safely exceed the available
cargo and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a trail-
er, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and
luggage load capacity of your
vehicle.

Driving tips
WEIGHT OF THE VEHICLE - WITH AND WITHOUT A TRAILER
This section will guide you in the
proper loading of your vehicle and/or
trailer, to keep your loaded vehicle
weight within its design rating capa-
bility, with or without a trailer.
Properly loading your vehicle will
provide maximum return of the vehi-
cle design performance. Before load-
ing your vehicle, familiarize yourself
with the following terms for determin-
ing your vehicle's weight ratings, with
or without a trailer, from the vehicle's
Specifications and the compliance
label:
Base curb weight
This is the weight of the vehicle
including a full tank of fuel and all
standard equipment. It does not
include passengers, cargo, or option-
al equipment.
Vehicle curb weight
This is the weight of your new vehicle
when you picked it up from your deal-
er plus any aftermarket equipment.
Cargo weight
This figure includes all weight added
to the Base Curb Weight, including
cargo and optional equipment. When
towing, trailer tongue load or king pin
weight also is part of the Cargo
Weight.
GAW (Gross axle weight)
This is the total weight placed on
each axle (front and rear) - including
vehicle curb weight and all payload.
GAWR (Gross axle weight rating)
This is the maximum allowable
weight that can be carried by a single
axle (front or rear). These numbers
are shown on the compliance label.
The total load on each axle must
never exceed its GAWR.
GVW (Gross vehicle weight)
This is the Base Curb Weight plus
actual Cargo Weight plus passen-
gers.
GVWR (Gross vehicle weight
rating)
This is the maximum allowable
weight of the fully loaded vehicle
(including all options, equipment,
passengers and cargo). The GVWR
is shown on the compliance label
located on the driver's door pillar.
GCW (Gross Combined
Weight)
This is the weight of the loaded vehi-
cle (GVW) plus the weight of the fully
loaded trailer.

Driving tips
30 5
GCWR (Gross Combined
Weight Rating)
This is the maximum allowable
weight of the vehicle and the loaded
trailer - including all cargo and pas-
sengers - that the vehicle can handle
without risking damage. (Important :
The towing vehicle's braking system
is rated for operation at GVWR, not
GCWR. Separate functional brakes
should be used for safe control of
towed vehicles and for trailers weigh-
ing an 750kg (1,653 lbs).) The GCW
must never exceed the GCWR.
Maximum Trailer Weight
This is the highest possible weight of
a fully loaded trailer the vehicle can
tow. It assumes a vehicle with only
mandatory options, no cargo, and a
driver. The weight of other optional
equipment, passengers and cargo in
your vehicle will reduce the maxi-
mum trailer weight your vehicle can
tow.
Calculating the load your vehi-
cle can tow
1. Use the appropriate maximum
GCWR chart (in the Weight of the
Trailer section in this chapter) for
your type of drive system and
transmission.
2. Weigh your vehicle.
3. Subtract the weight of your vehicle
from the maximum GCWR in the
chart. This is the maximum trailer
weight your vehicle can tow. It
must be below the maximum trail-
er weight shown in the chart. Note
that the maximum trailer weight
your vehicle can tow depends on
the total weight of any cargo, pas-
sengers and available equipment
in the vehicle.

Driving tips
TRAILER TOWING
To identify what the vehicle trailering
capacity is for your vehicle, you should
refer to the chart on this page.
WARNING- Towing a trail-
er
If you don't 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 pas-
sengers could be seriously or fatal-
ly injured. Pull a trailer only if you
have followed all the steps in this
section.
WARNING- Weight limits
Before towing, make sure the total
trailer weight, gross combination
weight, gross vehicle weight, gross
axle weight and trailer tongue load
are all within the limits.

NOTICE
• For definitions of terms used in this table and instructions on how to calculate
your vehicle load, refer to Weight of the Vehicle in this chapter.
• The combined weight of the completed towing vehicle and the loaded trailer must
not exceed the GCWR.
• When towing maximum loads under high outside temperatures and/or on steep
grades, the A/C system may cycle on and off to protect the engine from overheat-
ing. This may result in a temporary increase of interior temperature.
CAUTION
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 section.

Remember that trailering is different than
just driving your vehicle by itself.
Trailering causes major changes in han-
dling, durability, and fuel economy.
Successful, safe trailering requires cor-
rect equipment, and cautious driving.
This section contains many time-tested,
important trailering tips and safety rules.
Many of these are important for your
safety and that of your passengers.
Please read this section carefully before
you pull a trailer.
Load-pulling components such as the
engine, transmission, wheel assemblies,
and tires are forced to work harder
against the load of the added weight. The
engine is required to operate at relatively
higher speeds and under greater loads.
This additional burden generates extra
heat. The trailer also adds considerably
to wind resistance, increasing the pulling
requirements.If you do decide to pull a trailer
Here are some important points if you
decide to pull a trailer:
• State, provincial, county and municipal
government have varying trailering
laws. Make sure your hitch, mirrors,
lights and wiring arrangements are
legal, not only where you live, but also
where you’ll be driving. A good source
for this information is state or local law
enforcement agencies.
• Consider using a sway control. You can
ask a hitch dealer about sway control.
• After your odometer indicates 800 km
(500 miles) or more, you can tow a
trailer. For the first 800 km (500 miles)
that you tow a trailer, don’t drive over
80 km/h (50 mph) and don’t make
starts at full throttle. This helps your
engine and other parts of your vehicle
“wear” in at the heavier loads.
• Always drive your vehicle at a moder-
ate speed (less than 100 km/h (60
mph)).
• On a long uphill grade, do not exceed
70 km/h (45 mph) or the posted towing
speed limit, whichever is lower.
• The important considerations have to
do with weight:
Weight of the trailer
How heavy can a trailer safely be? It
should never weigh more than the maxi-
mum trailer weight with trailer brakes. But
even that can be too heavy.
It depends on how you plan to use your
trailer. For example, speed, altitude, road
grades, outside temperature and how
much your vehicle is used to pull a trailer
are all important. The ideal trailer weight
can also depend on any special equip-
ment that you have on your vehicle.

Driving tips
Weight of the trailer tongue
The tongue load of any trailer is an
important weight to measure because it
affects the total gross vehicle weight
(GVW) of your vehicle. This weight
includes the curb weight of the vehicle,
any cargo you may carry in it, and the
people who will be riding in the vehicle.
And if you will tow a trailer, you must add
the tongue load to the GVW because
your vehicle will also be carrying that
weight.
The trailer tongue should weigh a maxi-
mum of 10% of the total loaded trailer
weight. 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
correct them simply by moving some
items around in the trailer.
Hitches
It's important to have the correct hitch
equipment. Crosswinds, large trucks
going by, and rough roads are a few rea-
sons why you’ll need the right hitch. Here
are some rules to follow:
• 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, as well as dirt and
water.
• The bumpers on your vehicle are not
intended for hitches. Do not attach
rental hitches or other bumper-type
hitches to them. Use only a frame-
mounted hitch that does not attach to
the bumper.WARNING - Trailer
• Never load a trailer with more
weight in the rear than in the
front. The front should be loaded
with approximately 60% of the
total trailer load; the rear should
be loaded with approximately
40% of the total trailer load.
• Never exceed the maximum
weight limits of the trailer or trail-
er towing equipment. Improper
loading can result in damage to
your vehicle and/or personal
injury. Check weights and loading
at a commercial scale or highway
patrol office equipped with
scales.
• An improperly loaded trailer can
cause loss of vehicle control.
