Loading InformationDefinitionsThe towing capacity (gross weight of the trailer)
is the sum of the trailer's empty weight and the
weight of the load.
The vertical coupling load is the weight that the
trailer drawbar exerts on the trailer coupling of the
vehicle.
The rear-axle load is the vehicle weight on the
rear axle plus the weight of the transported load
and the vertical coupling load of the trailer.
The gross weight of the vehicle and trailer is
the sum of the weight of the towing vehicle and the
weight of the trailer.
The Curb weight - actual weight of your vehicle -
vehicle weight including standard and optional
equipment, fluids, emergency tools, and spare tire
assembly. This weight does not include passen-
gers and cargo.
The Gross Vehicle Weight is sum of the curb
weight and the weight of passengers and cargo
combined.
The Gross Vehicle Weight Rating is the maxi-
mum total weight of vehicle, passengers, lug-
gage, hitch, trailer tongue load and optional equip-
ment.The Gross Axle Weight Rating is the maximum
load limit for the front or the rear axle. This infor-
mation is located on the safety comliance sticker
located in the driver’s side door jamb.
For determining the compatibility of the tire and
vehicle load capabilities:
fPlease observe the chapter “TIRES, RIMS,
TRACKS” on Page 368.
The load capacity coefficient (e.g. “106”) is a min-
imum requirement. For more information:
fPlease observe the chapter “INSCRIPTION ON
RADIAL TIRE” on Page 297.
The Gross Combined Weight Rating is the
maximum total weight rating of vehicle, passen-
gers, cargo and trailer.
The Vehicle Capacity Weight - Load Limit - is
the maximum total weight limit specified of the
load (passengers and cargo) for the vehicle. This
is the maximum weight of passengers and cargo
that can be loaded into the vehicle. This informa-
tion can be found on the tire pressure plate.
If a trailer is being towed, the trailer tongue weight
must be included as part of the cargo load.
The maximum loaded vehicle weight is the
sum of curb weight, accessory weight, vehicle ca-
pacity weight and production options weight.
The load rating is the maximum load that a tire
is rated to carry for a given inflation pressure.The maximum load rating is the load rating for
a tire at the maximum permissble inflation pressu-
re.
The cargo capacity is the permissible weight of
cargo, the substracted weight of passengers from
the load limit.
fNever exceed the permissible limits.
Danger!
Risk of personal injury or death.
Injuries are much more likely in an accident
if persons ride in the cargo area.
fPersons must ride only on the seats provided
for this purpose.
fMake sure that everybody fastens their safety
belts.
Risk of personal injury, loss of control and
damage to vehicle.
fNever exceed the specified axle loads.Over-
loading can shorten the service life of the tires
and car, as well as lead to dangerous vehicle
reactions and long braking distances. Damage
due to overloading is not covered by the vehi-cle warranty.

Controls, Safety, Instruments
Example for determining the combined weight of occu-
pants and cargoVehicle Load CapacityfThe combined weight of occupants and cargo
should never exceed the weight shown on the
tire plate in the vehicle.
Please observe the chapter “TIRE PRESSURE
PLATE” on Page 289.
fNever exceed the number of passengers
shown on the tire pressure plate in the vehicle.Determing the combined weight of
occupants and cargo:
fAdd the weight of all occupants and then add
the total luggage weight (figure).
Steps for determing correct load limit
1. Locate the statement "The combined weight of
occupants and cargo should never exceed XXX
pounds" on your vehicle’s placard (depending
on the date of manufacture).
2. Determine the combined weight of the driver
and passengers that will be riding in your vehi-
cle.
3. Subtract the combined weight of the driver and
passengers from XXX kilograms or XXX
pounds.
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 car-
go 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 re-
duces the available cargo and luggage load ca-
pacity of your vehicle.
Practical Tips, Minor Repairs
343
Emergency Starting with Jumper
CablesIf the battery is discharged, e.g. in winter or after
the car has been parked for a long time, the bat-
tery of another car can be used for starting with
the help of jumper cables.
Make sure the voltage of both batteries is the
same.
The capacity (Ampere hours, Ah) of the booster
battery must not be substantially less than that of
the discharged battery.The discharged battery
must be correctly connected to the vehicle's elec-
trical system.
fPlease observe the chapter “BATTERY” on
Page 332.
Note
Do not try to start the car by pushing or towing.
Damage to the catalytic converters and other
components of the car may result.
Danger!
Risk of damage and serious personal injury
due to short circuit.
fUse only jumper cables of adequate diameter
cross-section and fitted with completely insu-
lated alligator clips.
fFollow all warnings and instructions of the
jumper cable manufacturer.
fWhen connecting jumper cables, make sure
that they cannot get caught in any moving
parts in the engine compartment.
The jumper cables must be long enough so
that neither vehicles nor cables touch another.
fThe vehicles must not be in contact, otherwise
current might flow as soon as the positive ter-
minals are connected.
fThe cable clamps must not be allowed to con-
tact each other when one end of the jumper ca-
bles are connected to a battery.
fCarefully ensure that tools or conductive jewel-
ery (rings, chains, watch straps) do not come
into contact with the positive jumper cable or
the positive battery post.
fImproper hook-up of jumper cables can ruin
the alternator.
Danger of caustic burns.
fDo not lean over the battery.Danger of gas explosion.
fImproper use of booster battery to start a ve-
hicle may cause an explosion, resulting in se-
vere personal injuries.
fKeep sources of ignition away from the bat-
tery, e.g. open flame, burning cigarettes or
sparking due to cable contact or welding work.
fA discharged battery can freeze even at
14°F (−10°C). Before connecting jumper ca-
bles, a frozen battery must be thawed out.
