Introduction41"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.
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.Fuel AdditivesHYUNDAI recommends that you use
good quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which help prevent
deposit formation in the engine. These
gasolines will help the engine run clean-
er and enhance performance of the
Emission Control System. For more infor-
mation 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, additives that you can buy
separately may be added to the gasoline.
If TOP TIER Detergent Gasoline is not
available, add one bottle of additive to the
fuel tank at every 7,500mile or every
engine oil change is recommended.
Additives are available from your author-
ized HYUNDAI dealer along with infor-
mation on how to use them. Do not mix
other additives.
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.
CAUTION
Your New Vehicle Limited Warrantymay not cover damage to the fuelsystem and any performance prob- lems that are caused by the use offuels containing methanol.
CAUTION
Never use gasohol which containsmethanol. Discontinue use of any gasohol product which impairs dri-vability.
CAUTION
Your New Vehicle Limited Warrantydoes not cover damage to the fuelsystem or any performance prob- lems caused by the use of “E85” fuel.

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

Parking brake & brake fluid
warning lightParking brake warning
This light is illuminated when the parking
brake is applied with the ignition switch in
the START or ON position. The warning
light should go off when the parking
brake is released.
Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and add
fluid as required. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are found, the warning light remains on or
the brakes do not operate properly.
Have the vehicle towed to any author-
ized HYUNDAI dealer for a brake sys-
tem inspection and necessary repairs. Your vehicle is equipped with a dual-
diagonal braking system. This means you
still have braking on two wheels even if
one of the brake circuits is damaged or
malfunctions. With only one of the circuits
working, more than normal pedal travel
and greater pedal pressure are required
to stop the car. Also, the car will not stop
in as short a distance with only a portion
of the brake system working. If the
brakes fail while you are driving, shift to a
lower gear for additional engine braking
and stop the car as soon as it is safe to
do so.
To check bulb operation, check whether
the parking brake and brake fluid warning
light illuminates when the ignition switch
is in the ON position.
WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorized HYUNDAI
dealer.
CAUTION
If the oil pressure warning light
stays on while the engine is run- ning, serious engine damage mayresult. The oil pressure warninglight comes on whenever there is insufficient oil pressure. In normaloperation, it should come on whenthe ignition switch is turned on,then go out when the engine is started. If the oil pressure warninglight stays on while the engine isrunning, there is a serious malfunc-tion.
If this happens, stop the car assoon as it is safe to do so, turn offthe engine and check the oil level. Ifthe oil level is low, fill the engine oil to the proper level and start theengine again. If the light stays onwith the engine running, turn theengine off immediately. In any instance where the oil light stays onwhen the engine is running, theengine should be checked by an authorized HYUNDAI dealer beforethe car is driven again.

WARNING
- ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the win-
dows immediately.
• Do not inhale exhaust fumes.Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxia-
tion.
 Be sure the exhaust system does not leak. The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you hear
a change in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, have the
exhaust system checked as soon as possible by an authorized HYUNDAI dealer.
 Do not run the engine in an enclosed area. Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine in your
garage any longer than it takes to start the engine and back the car out.
 Avoid idling the engine for prolonged periods with people inside the car. If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area
with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior.
If you must drive with the trunk lid open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshield are
kept clear of snow, ice, leaves or other obstructions.
