G020200AFD-EA Owner maintenance precautions
Improper or incomplete service may
result in problems. This section gives
instructions only for the maintenance
items that are easy to perform.
As explained earlier in this section, sev-
eral procedures can be done only by an
authorised HYUNDAI dealer with special
tools.
✽✽NOTICE
Improper owner maintenance during the warranty period may affect warran-
ty coverage. For details, read the sepa-
rate Service Passport provided with the
vehicle. If you're unsure about any serv-
icing or maintenance procedure, have itdone by an authorised HYUNDAI deal-
er.
WARNING - Maintenance
work
Performing maintenance work on a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorised HYUNDAI dealer.
Working under the bonnet with the engine running is dangerous.
It becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while work-
ing under the bonnet, make cer-
tain that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and all
neckties, scarves, and similar
loose clothing before gettingnear the engine or cooling fans.WARNING - Diesel Engine
Never work on injection system with engine running or within 30
seconds after shutting off engine.
High-pressure pump, rail, injectorsand high-pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touches the body.
People using pacemakers shouldnot be within 30cm of the ECU orwiring harness within the engine
room while engine is running, since
the high currents in the electronic
engine control system produce
considerable magnetic fields.
