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.
Vehicle capacity weight
904 lbs. (410 kg)
Vehicle capacity weight is the maximum
combined weight of occupants and
cargo. If your vehicle is equipped with a
trailer, the combined weight includes the
tongue load.
Seating capacity
Total: 5 persons (Front seat : 2 persons,
Rear seat : 3 persons)
Seating capacity is the maximum
number of occupants including a driver,
your vehicle may carry. However, the
seating capacity may be reduced based
upon the weight of all of the occupants,
and the weight of the cargo being carried
or towed. Do not overload the vehicle as
there is a limit to the total weight, or load
limit including occupants and cargo, the
vehicle can carry.
Towing capacity
We do not recommend using this vehicle
for trailer towing.
Cargo capacity
The cargo capacity of your vehicle will
increase or decrease depending on the
weight and the number of occupants
and the tongue load, if your vehicle is
equipped with a trailer.

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 figure equals the available amount of cargo and
luggage load capacity. For example,
if the "XXX" amount equals 1400
lbs. and there will be five 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.)
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 trailer, 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.
WARNING
Do not overload the vehicle as there
is a limit to the total weight, or load
limit, including occupants and cargo,
the vehicle can carry. Overloading can
shorten the life of the vehicle. If the
GVWR or the GAWR is exceeded, parts
on the vehicle can break, and it can
change the handling of your vehicle.
These could cause you to lose control
and result in an accident.

Certification label
OBH059070OBH059070
The certification label is located on the
driver’s door sill at the center pillar and
shows the maximum allowable weight of
the fully loaded vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight of the vehicle,
all occupants, fuel and cargo.
This label also tells you the maximum
weight that can be supported by the
front and rear axles, called Gross Axle
Weight Rating (GAWR).
The total weight of the vehicle, including
all occupants, accessories, cargo, and
trailer tongue load must not exceed the
Gross Vehicle Weight Rating (GVWR) or
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. Be sure
to spread out your load equally on both
sides of the centerline.
WARNING
Overloading
• Never exceed the GVWR for your
vehicle, the GAWR for either the front
or rear axle and vehicle capacity
weight. Exceeding these ratings
can affect your vehicle’s handling
and braking ability, and cause an
accident.
• Do not overload your vehicle.
Overloading your vehicle can cause
heat buildup in your vehicle’s tires
and possible tire failure, increased
stopping distances and poor vehicle
handling-all of which may result in a
crash.
NOTICE
Overloading your vehicle may cause
damage. Repairs would not be covered
by your warranty. Do not overload your
vehicle.
WARNING
If you carry items inside your vehicle
(e.g., suitcases, tools, packages, or
anything else), they are moving as fast
as the vehicle. If you have to stop or
turn quickly, or if there is a crash, the
items will keep going and can cause
an injury if they strike the driver or a
passenger.
• Put items in the cargo area of your
vehicle. Try to spread the weight
evenly.
• Do not stack items, like suitcases,
inside the vehicle 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.
