Introduction4
1"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15 per-
cent gasoline, and is manufactured
exclusively for use in Flexible Fuel
Vehicles. “E85” is not compatible with
your vehicle. Use of “E85” may result in
poor engine performance and damage to
your vehicle's engine and fuel system.
HYUNDAI recommends that customers
do not use fuel with an ethanol content
exceeding 10 percent.
Use of MTBEHYUNDAI recommends avoiding fuels
containing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen Content
2.7% weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapor lock or hard starting.
Do not use methanolFuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system.Gasolines for cleaner airTo help contribute to cleaner air,
HYUNDAI recommends that you use
gasolines treated with detergent addi-
tives, which help prevent deposit forma-
tion in the engine. These gasolines will
help the engine run cleaner and enhance
performance of the Emission Control
System.Operation in foreign countriesIf you are going to drive your vehicle in
another country, be sure to:
• Observe all regulations regarding reg-
istration and insurance.
• Determine that acceptable fuel is avail- able.

Introduction
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, economy 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 needed to
properly break-in the engine.
• Avoid hard stops, except in emergen- cies, to allow the brakes to seat prop-
erly.
• Don't let the engine idle longer than 3 minutes at one time.
• Don't tow a trailer during the first 1,200 miles (2,000 km) of operation.VEHICLE BREAK-IN PROCESS
