0 Note
• The vehicle capacity weight figures apply when the load is
distributed evenly in the vehicle (passengers and luggage). When
transporting a heavy load in the luggage compartment, carry the
load as near to the rear axle as possible so that the vehicle's
handling is not impaired.
• Do not exceed the maximum permissible axle loads or the
maximum gross vehic le weight. Always remember that the vehic le's
handling will be affected by the extra load. Therefore, adjust your
speed accordingly .
• Always observe local regulations. •
Dimensions
The specifications refer to the basic model. Differences may occur
depending on the mode l type and options ordered, for example, tire
sizes.
0 Note
When driving up steep ramps, on rough roads, over curbs, etc. it is
important to remember that some parts of your vehicle, such as
spoilers or exhaust system components, may be close to the
ground. Be careful not to damage them. •

that automobiles meet specific emission regu lations and safety .,_

standards. Therefore, vehicles built for the U.S .A. and Canada differ
from vehicles sold in other countries.
If you plan to take your vehicle outside the continental limits of the
United States or Canada, there is the possibility that
• unleaded fuels for vehicles with catalytic converter may not be
available;
• fuel may have a considerably lower octane rating. Improper fuel
may cause engine damage;
• service may be inadequate due to lack of proper service facilities,
tools or testing equipment;
• replacement parts may not be readily available .
• Navigation systems for vehicles built for the U.S.A. and Canada
will not necessarily work in Europe , and may not work in other coun­
tries outside of North America.

Maintenance
General
Your vehicle has been designed to help keep maintenance require­
ments to a minimum. However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle 's safety, economy and
reliability. For detailed vehicle maintenance consult your Mainte­
nance & Warranty booklet .
Under difficult operating conditions, for example at extremely low
outside temperatures, in very dusty regions, when towing a trailer
very frequently, etc., some service work should be performed
between the intervals specified. This applies particularly to:
• oil changes , and
• cleaning or replacing the air filter.
~ For the sake of the environment
By regularly maintaining your vehicle, you help make sure that emis ­
sion standards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the generally increasing technical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by vehicle
owners. Also, safety and environmental concerns place very strict
limits on the nature of repairs and adjustments to engine and trans­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment available to specially trained .,_

the ground, always make sure the vehicle is on level ground , that
the wheels are always securely blocked and that the engine
cannot be started .
