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.

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

WARNING
- Cargo
Cargo should always be secured to
prevent it from being thrown about
the vehicle in a collision and caus-
ing injury to the vehicle occupants.
Do not place objects in the rear
seats, since they cannot be proper-
ly secured and may hit the front
seat occupants in a collision.
CAUTION
- Rear seat belts
When returning the rear seatbacks
to the upright position, rememberto return the rear shoulder belts totheir proper position. Routing the seat belt webbing through the rearseat belt guides will help keep thebelts from being trapped behind or under the seats.
CAUTION -
Damaging rear
seat belt buckles
When you fold the rear seatback,
insert the buckle in the pocketbetween the rear seatback and cushion. Doing so can prevent thebuckle from being damaged by the rear seatback.
WARNING -
Cargo loading
Make sure the engine is off, the
automatic transaxle is in P (Park)
or the manual transaxle is in R
(Reverse) or 1st, and the parking
brake is securely applied whenever
loading or unloading cargo. Failure
to take these steps may allow the
vehicle to move if the shift lever is
inadvertently moved to another
position.
WARNING
When you return the rear seatback
to its upright position after being
folded down:
Be careful not to damage the seat
belt webbing or buckle. Do not
allow the seat belt webbing or
buckle to get caught or pinched in
the rear seat. Ensure that the seat-
back is completely locked into its
upright position by pushing on the
top of the seatback. Otherwise, in
an accident or sudden stop, the
seat could fold down and allow
cargo to enter the passenger com-
partment, which could result in
serious injury or death.
