Und er di ffi cult ope rating cond ition s, for example at extremely low
outside temperatures, in very dusty regions, when towing a trailer
very frequen tly, etc., some service work shou ld be performed
between the intervals specified. This applies particularly to:
• oil changes, and
• cleaning or replacing the air filter.
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 general ly increasing technical
complexity of today's automobi les, have steadi ly reduced the scope
of maintenance and repa irs which can be carried out by vehicle
owners.
Al so, sa fety a nd e nvironment al concerns p lace very strict
limi ts on the na ture of repairs a nd adjustments to engine and trans ­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing dev ices and other equipment ava ilable to specially trained
workshop personnel in order to assure proper performance, reli ­
ability and safety of the vehicle and its many systems.
Improper maintenance, adjustments and repairs can impair the
ope ration and re liability of your vehic le and even void your vehic le
warranty. Therefore, proof of servicing in accordance with the main­
tenance schedu le may be a condition for upholding a pos sible
warranty claim made within the warranty period. Above all, operational safety can be adversely affected, creating
unnecessary r isks for you and your passengers .

dea ler or any other properly equipped and qualified workshop. We

nity to perform all scheduled maintenance and necessary repairs.
