of the vehicle, as
R the panorama roof* may be damaged, thus
injuring persons
R this can have a substantial adverse
effect on the driving dynamics of the
vehicle, thus causing accidents
R the rack and/or the load could detach and
through this cause an accident or other
people could be injured by the load and/
or rack that has fallen off
GWarning!
Make sure the tailgate is closed when the
engine is running and while driving.
Among other dangers, deadly carbon
monoxide (CO) gases may enter vehicle
interior resulting in unconsciousness and
death.
GWarning!
Do not store any flammable substances
inside the vehicle that could ignite and
start a fire.
GWarning!
The manufacturer has not approved your
vehicle for towing a trailer. A trailer can
permanently impair driving safety.
The gross vehicle weight which is the
weight of the vehicle including fuel, tools,
installed accessories, passengers, and
luggage/cargo must never exceed the load
limit and the Gross Vehicle Weight Rating
(GVWR) for your vehicle as specified on the
placard located on the driver’s door
B‑pillar ( Y page 198). In addition, the
load must be distributed in such a way so
that the weight on each axle never exceeds
the Gross Axle Weight Rating (GAWR) for the
front and rear axle. The GVWR and GAWR for
your vehicle are indicated on the
certification label which can be found on
the driver’s door B‑pillar.
For more information, see “Loading the
vehicle” ( Y page 120).
The handling characteristics of a fully
loaded vehicle depend greatly on the load
distribution. It is therefore recommended
to load the vehicle with the heaviest items
being placed towards the front of the
vehicle.
Please pay attention to and comply with the
following instructions when loading the
vehicle and transporting cargo:
R Always place items being carried
against seat backrests, and fasten them
as securely as possible.
R The heaviest portion of the cargo should
always be kept as low as possible against
seat backrests.
R Do not stack loads higher than the top
edge of the head restraints.
R Make sure no luggage/cargo items can get
above or next to the driver’s and/or
passenger seat into the passenger
compartment.
R Make sure luggage/cargo is properly
secured.
R Always use, if so equipped, cargo net*
when transporting cargo.

Loading the vehicle
Two labels on your vehicle show how much
weight it may properly carry.
1)The Tire and Loading Information
placard can be found on the driver’s
door B‑pillar. This placard tells you
important information about the
number of people that can be in the
vehicle and the total weight that can be
carried in the vehicle. It also contains
information on the proper size and
recommended tire inflation pressures
for the original equipment tires on
your vehicle.2)The certification label, also found on
the driver’s door B‑pillar, tells you
about the gross weight capacity of your
vehicle, called the Gross Vehicle
Weight Rating (GVWR). The GVWR
includes the weight of the vehicle, all
occupants, fuel and cargo. The
certification label also tells you about
the front and rear axle weight capacity,
called the Gross Axle Weight Rating(GAWR). The GAWR is the total allowable
weight that can be carried by a single
axle (front or rear). Never exceed the
GVWR or GAWR for either the front axle
or rear axle.0046Driver’s door B‑pillar
Following is a discussion on how to work
with the information contained on the Tire
and Loading Information placard with
regards to loading your vehicle.
Tire and Loading Information
GWarning!
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.

The Tire and Loading Information placard
showing load limit information 0046 is
located on the driver’s door B‑pillar
( Y page 120).
XLocate the statement “The combined
weight of occupants and cargo should
never exceed XXXX kg or XXXX lbs.” on the
Tire and Loading Information placard.
The combined weight of all occupants and
cargo/luggage should never exceed the
weight referenced in that statement.
Seating capacity
The seating capacity gives you important
information on the number of occupants
that can be in the vehicle. The Tire and
Loading Information placard showing
seating capacity 0046 is located on the
driver’s door B‑pillar ( Y page 120).
i Data shown on Tire and Loading
Information placard example are for
illustration purposes only. Seating
capacity data are specific to each
vehicle and may vary from data shown in
the following illustration. Refer to Tire
and Loading Information placard on
vehicle for actual data specific to your
vehicle.
Steps for determining correct load limit
The following steps have been developed as
required of all manufacturers under
Title 49, Code of U.S. Federal Regulations,
Part 575 pursuant to the “National Traffic
and Motor Vehicle Safety Act of 1966”.XStep 1: Locate the statement “The
combined weight of occupants and cargo
should never exceed XXXX kg or
XXXX lbs.” on your vehicle’s Tire and
Loading Information placard.XStep 2: Determine the combined weight of
the driver and passenger that will be
riding in your vehicle.XStep 3: Subtract the combined weight of
the driver and passenger from
XXXX kilograms or XXXX lbs.XStep 4: The resulting figure equals the
available amount of cargo and luggage
load capacity. For example, if the “XXXX”
amount equals 540 lbs and there will be
one 150 lbs passenger in your vehicle, the
amount of available cargo and luggage
load capacity is 390 lbs
(540 lbs - 150 lbs = 390 lbs).XStep 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.
i The maximum cargo compartment load
is 110 lbs (50 kg).
Tires and wheels121>> Operation.451_AKB; 3; 22, en-USd2ureepe,Version: 2.11.8.12009-07-27T09:36:34+02:00 - Seite 121Z

The following table shows examples on how to calculate total and cargo load capacities
with varying seating configurations and number and size of occupants. The following
examples use a load limit of 540 lbs. This is for illustration purposes only . Make sure
you are using the actual load limit for your vehicle stated on the vehicle’s Tire and
Loading Information placard ( Y page 120).Example 1Example 2Step 1Combined weight limit of
occupants and cargo from Tire and
Loading Information placard540 lbs540 lbsStep 2Number of occupants (driver and

limit from Tire and Loading
Information placard minus
combined weight of all occupants)540 lbs - 330 lbs =
210 lbs540 lbs - 150 lbs =

The higher the weight of all occupants, the less cargo and luggage load capacity is
available.
Certification label
Even after careful determination of the
combined weight of all occupants and cargo
as to not exceed the permissible load
limit, you must make sure your vehicle
never exceeds the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for either the front or rear
axle. You can obtain the GVWR and GAWR
from the certification label. The
certification label can be found on the
driver’s door B‑pillar, see “Technical
data” ( Y page 198).
Gross Vehicle Weight Rating (GVWR) means:
The total weight of the vehicle, all
occupants, and all cargo must never exceed
the GVWR.
Gross Axle Weight Rating (GAWR) means:
The total allowable weight that can be
carried by a single axle (front or rear).To assure that your vehicle does not exceed
the maximum permissible weight limits
(GVWR and GAWR for front and rear axle),
have the loaded vehicle (including driver,
passenger, and all cargo) weighed on a
suitable commercial scale.
Maximum tire load
GWarning!
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.

cargo load capacities ( Y page 121).
Direction of rotation
Unidirectional tires offer added
advantages, such as better hydroplaning
performance. To benefit, however, you must
make sure the tires rotate in the direction
specified.
An arrow on the sidewall indicates the
intended direction of rotation (spinning)
of the tire.
Tire care and maintenance
GWarning!
Regularly check the tires for damage.
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle.
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
Check the tire inflation pressure at least
once a month. For more information on
checking tire inflation pressure, see
“Recommended tire inflation pressure”
( Y page 115).
Tire inspection
Every time you check the tire inflation
pressure, you should also inspect your
tires for the following
R excessive treadwear ( Y page 123)
R cord or fabric showing through the tire’s
rubber
R bumps, bulges, cuts, cracks or splits in
the tread or side of the tire
Replace the tire if you find any of the above
conditions.
Life of tire
GWarning!
Tires should be replaced after 6 years,
regardless of the remaining tread.
The service life of a tire is dependent upon
varying factors including but not limited
to
R driving style
R tire inflation pressure
R distance driven
Tread depth
GWarning!
Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately 1
/ 16 in
(1.6 mm), we recommend that you do not allow
your tires to wear down to that level. As
tread depth approaches 1
/ 8 in (3 mm), the
adhesion properties on a wet road are
sharply reduced.
