Detergent Fuel Additives
HYUNDAI recommends that you use 
good quality gasolines treated with 
detergent additives such as TOP TIER 
Detergent Gasoline, which help prevent 
deposit formation in the engine. These 
gasolines will help the engine run 
cleaner and enhance performance 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, detergent-based 
fuel additives that you can purchase 
separately may be added to the gasoline. 
If TOP TIER Detergent Gasoline is 
not available, one bottle of additive 
added to the fuel tank according to the 
maintenance schedule is recommended 
(refer to the Maintenance Schedule in 
chapter 9).
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. •  This vehicle should not be modified. 
Modification of your vehicle could 
affect its performance, safety or 
durability and may even violate 
governmental safety and emissions 
regulations.
In addition, damage or performance 
problems resulting from any 
modification may not be covered 
under warranty.
•  If you use unauthorized electronic  devices, it may cause the vehicle to 
operate abnormally, wire damage, 
battery discharge and fire. For your 
safety, do not use unauthorized 
electronic devices.
VEHICLE BREAK-IN 
PROCESS
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.
•  Fuel economy and engine  performance may vary depending 
on vehicle break-in process and be 
stabilized after 4,000 miles (6,000 
km). New engines may consume more 
oil during the vehicle break-in period.
•  Avoid hard stops, except in  emergencies, to allow the brakes to 
seat properly.

Seats & Safety System3-2
You will find many safety precautions 
and recommendations throughout this 
section, and throughout this manual. 
The safety precautions in this section are 
among the most important.
Always Wear Your Seat Belt
A seat belt is your best protection in all 
types of accidents. Air bags are designed 
to supplement seat belts, not replace 
them. So even though your vehicle is 
equipped with air bags, ALWAYS make 
sure you and your passengers wear your 
seat belts, and wear them properly.
Restrain All Children
All children under age 13 should ride 
in your vehicle properly restrained in a 
rear seat, not the front seat. Infants and 
small children should be restrained in 
an appropriate child restraint. Larger 
children should use a booster seat with 
the lap/shoulder belt until they can use 
the seat belt properly without a booster 
seat.
Air Bag Hazards
While air bags can save lives, they can 
also cause serious or fatal injuries to 
occupants who sit too close to them, or 
who are not properly restrained. Infants, 
young children, and shorter adults are at 
the greatest risk of being injured by an 
inflating air bag. Follow all instructions 
and warnings in this manual.
Driver Distraction
Driver distraction presents a serious and 
potentially deadly danger, especially for 
inexperienced drivers. Safety should be 
the first concern when behind the wheel, 
and drivers need to be aware of the wide 
array of potential distractions, such as 
drowsiness, reaching for objects, eating, 
personal grooming, other passengers, 
and using cellular phones. Drivers can become distracted when 
they take their eyes and attention off 
the road or their hands off the wheel to 
focus on activities other than driving. To 
reduce your risk of distraction or getting 
into an accident:
•  ALWAYS set up your mobile devices 
(for example, MP3 players, phones, 
navigation units, etc.) when your 
vehicle is parked or safely stopped.
•  ONLY use your mobile device when  allowed by laws and when conditions 
permit safe use. NEVER text or email 
while driving. Most states have laws 
prohibiting drivers from texting. Some 
states and cities also prohibit drivers 
from using handheld phones.
•  NEVER let the use of a mobile device  distract you from driving. You have a 
responsibility to your passengers and 
others on the road to always drive 
safely, with your hands on the wheel 
as well as your eyes and attention on 
the road.
Control Your Speed
Excessive speed is a major factor in crash 
injuries and deaths. Generally, the higher 
the speed, the greater the risk, but 
serious injuries can also occur at lower 
speeds. Never drive faster than is safe 
for current conditions, regardless of the 
maximum speed posted.
Keep Your Vehicle in Safe 
Condition
Having a tire blowout or a mechanical 
failure can be extremely hazardous. To 
reduce the possibility of such problems, 
check your tire pressures and condition 
frequently, and perform all regularly 
scheduled maintenance.

Chain Installation
When installing AutoSock (fabric snow 
chain
), follow the manufacturer’s 
instructions and mount them as tightly 
as possible. Drive slowly (less than 20 
mph (30 km/h)) with chains installed. If 
you hear the chains contacting the body 
or chassis, stop and tighten them. If they 
still make contact, slow down until the 
noise stops. Remove the AutoSock(fabric 
snow chain) as soon as you begin 
driving on cleared roads.When mounting 
AutoSock (fabric snow chain), park the 
vehicle on level ground away from traffic. 
Turn on the vehicle Hazard Warning 
Flasher and place a triangular emergency 
warning device behind the vehicle (if 
available).Always place the vehicle in 
P (Park), apply the parking brake and 
turn off the engine before installing tire 
chains.
NOTICE
When using AutoSock (fabric snow 
chain):
•  Wrong size chains or improperly 
installed chains can damage your 
vehicle's brake lines, suspension, 
body and wheels.
•  If you hear noise caused by chains 
contacting the body, retighten the 
chain to prevent contact with the 
vehicle body.
•  To prevent body damage, retighten 
the chains after driving 0.3-0.6 miles 
(0.5-1.0 km). 
Winter Precautions
Use high quality ethylene glycol 
coolant
Your vehicle is delivered with high 
quality ethylene glycol coolant in the 
cooling system. It is the only type of 
coolant that should be used because it 
helps prevent corrosion in the cooling 
system, lubricates the water pump and 
prevents freezing. Be sure to replace or 
replenish your coolant in accordance 
with the maintenance schedule in 
chapter 8. Before winter, have your 
coolant tested to assure that its freezing 
point is sufficient for the temperatures 
anticipated during the winter.
Change to "winter weight" oil if 
necessary
In some climates it is recommended that 
a lower viscosity "winter weight" oil be 
used during cold weather. See chapter 8 
for recommendations. If you aren't sure 
what weight oil you should use, consult 
an authorized HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on the 
battery system. Visually inspect the 
battery and cables as described in 
chapter 8. The level of charge in your 
battery can be checked by an authorized 
HYUNDAI dealer or a service station.
Check spark plugs and ignition 
system
Inspect your spark plugs as described in 
chapter 8 and replace them if necessary. 
Also check all ignition wiring and 
components to be sure they are not 
cracked, worn or damaged in any way.
