Introduction
For customers who do not use TOP
Tier Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, addi-
tives that you can buy separately
may be added to the gasoline. If TOP
TIER Detergent Gasoline is not avail-
able, one bottle of additive added to
the fuel tank at every 7,500 miles or
12 months is recommended.
Additives are available from your
authorized HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
Observe all regulations regarding registration and insurance.
Determine that acceptable fuel is available. No special break-in period is needed.
By following a few simple precautions
for the first 600 miles (1,000 km) you
may add to the performance, econo-
my and life of your vehicle.
Do not race the engine.
While driving, keep your engine
speed (rpm, or revolutions per
minute) between 2,000 rpm and
4,000 rpm.
Do not maintain a single speed for long periods of time, either fast or
slow. Varying engine speed is need-
ed to properly break-in the engine.
Avoid hard stops, except in emer- gencies, to allow the brakes to seat
properly.
