Operating your vehicle
outside the U.S.A. or

proper service facilities, tools or testing
equipment;
- replacement parts may not be readily availa­
ble.

Important considerations for you and
your vehicle
The increasing use of e lectronics, sophisticat­
ed fue l injection and emission control sys­
tems, and the generally increasing technical
comp lexity of today's automob iles, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners .

miss ion parts which an owner can pe rform .
Ma intenance, adjustments and repa irs usually
require special tools, testing dev ices and oth­
e r equipment avai lab le to specia lly t ra ined

pa irs can impai r the operation and reliab ility
of your vehicle and even void you r vehicle war­
ranty . There fore, proof of servicing in accord­
ance wit h the ma intenance sched ule may be a
condition for upholding a poss ible warranty
claim made within the warranty period.

affected, c reating unnecessary risks for you
