Fuel Additives
Kia recommends that you use good
quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine
run cleaner and enhance perform-
ance of the Emission Control System.
For more information on TOP TIER
Detergent Gasoline, please go to the
website (www.toptiergas.com)
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 can be purchased sepa-
rately may be added to the gasoline.
If TOP TIER Detergent Gasoline is
not available, one bottle of additive
should be added to the fuel tank at
every 8,000 miles (13,000 km) or
every engine oil change is recom-
mended. Additives are available from
your authorized Kia 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 regardingregistration and insurance.
Determine that acceptable fuel is available.

affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronicdevices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your

While driving, keep your engine
speed (rpm, or revolutions per

bellow 4,000 rpm.
Do not maintain a single speed for long periods of time, either fast or
slow. Varying engine speed is
needed to properly break-in the
engine.
Avoid hard stops, except in emer- gencies, to allow the brakes to seat
properly.
Don't tow a trailer during the first 1,200 miles (2,000 km) of opera-
tion.
Fuel economy and engine perform- ance may vary depending on vehi-
cle break-in process and be stabi-
lized after 4,000 miles (6,000 km).
New engines may consume more oil
during the vehicle break-in period. 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.
Avoid hard stops, except in emer-
gencies, to allow the brakes to seat
