WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and
death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO can cause unconsciousness and death by asphyxiation.
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 vehicle, we recommend
that the exhaust system be 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. Run the engine only long enough to start the engine and to move the vehicle
out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle , be sure to do so only in an open area with the air intake set at “Fresh” and
fan control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes
located in front of the windshield clear of snow, ice, leaves, or other obstructions.
If you must drive with the tailgate/trunk open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at “Fresh”, the air flow control at “Floor” or “Face”, and the
fan control set to high.

Driving your vehicle
Before entering the vehicle
• Be sure all windows, outside mirror(s),
and outside lights are clean and
unobstructed.
• Remove frost, snow, or ice.
• Visually check the tires for uneven
wear and damage.
• Check under the vehicle for any sign
of leaks.
• Be sure there are no obstacles behind
you if you intend to back up.
Before starting
• Make sure the hood, the tailgate/
trunk, and the doors are securely
closed and locked.
• Adjust the position of the seat and
steering wheel.
• Adjust the inside and outside rearview
mirrors.
• Verify all the lights work.
• Fasten your seatbelt. Check that
all passengers have fastened their
seatbelts.
• Check the gauges and indicators in the
instrument panel and the messages
on the instrument display when the
ignition switch is in the ON position.
• Check that any items you are carrying
are stored properly or fastened down
securely.
WARNING
To reduce the risk of SERIOUS
INJURY or DEATH, take the following
precautions:
• ALWAYS wear your seat belt. All
passengers must be properly belted
whenever the vehicle is moving.
For more information, refer to “Seat
Belts” in chapter 3.
• Always drive defensively. Assume
other drivers or pedestrians may be
careless and make mistakes.• Stay focused on the task of driving.
Driver distraction can cause
accidents.
• Leave plenty of space between you
and the vehicle in front of you.
WARNING
NEVER drink or take drugs and drive.
Drinking or taking drugs and driving
is dangerous and may result in an
accident and SERIOUS INJURY or
DEATH.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Just
one drink can reduce your ability to
respond to changing conditions and
emergencies and your reaction time
gets worse with each additional drink.
Driving while under the influence
of drugs is as dangerous or more
dangerous than driving under the
influence of alcohol.
You are much more likely to have a
serious accident if you drink or take
drugs and drive. If you are drinking or
taking drugs, don’t drive. Do not ride
with a driver who has been drinking
or taking drugs. Choose a designated
driver or call a taxi.
BEFORE DRIVING

7-51
07
Snow or icy conditions
You need to keep sufficient distance
between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid
acceleration, sudden brake applications,
and sharp turns are potentially
very hazardous practices. During
deceleration, use engine braking to the
fullest extent. Sudden brake applications
on snowy or icy roads may cause skids
to occur.
To drive your vehicle in deep snow, it
may be necessary to use snow tires or to
install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, tow straps or
chains, a flashlight, emergency flares,
sand, a shovel, jumper cables, a window
scraper, gloves, ground cloth, coveralls,
a blanket, etc.
Snow tires
WARNING
Snow tires should be equivalent in size
and type to the vehicle’s standard tires.
Otherwise, the safety and handling of
your vehicle may be adversely affected.
If you mount snow tires on your vehicle,
make sure to use radial tires of the same
size and load range as the original tires.
Mount snow tires on all four wheels
to balance your vehicle’s handling in
all weather conditions. The traction
provided by snow tires on dry roads
may not be as high as your vehicle’s
original equipment tires. Check with
the tire dealer for maximum speed
recommendations.
We recommend you use snow tires
when road temperature is below 45°F
(7°C).
i Information
Do not install studded tires without first
checking local and municipal regulations
for possible restrictions against their use.
Tire chains
OBI3060007LOBI3060007L
Since the sidewalls of radial tires are
thinner than other types of tires, they
may be damaged by mounting some
types of tire chains on them. Therefore,
the use of snow tires is recommended
instead of tire chains. Do not mount
tire chains on vehicles equipped with
aluminum wheels; if unavoidable use
a wire type chain. If tire chains must
be used, use genuine HYUNDAI parts
and install the tire chain after reviewing
the instructions provided with the tire
chains. Damage to your vehicle caused
by improper tire chain use is not covered
by your vehicle manufacturer’s warranty.
WINTER DRIVING

7-53

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.
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.
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
2 for recommendations. If you aren’t
sure what weight oil you should use, we
recommend that you consult with an
authorized HYUNDAI dealer.
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.
To keep locks from freezing
To keep the locks from freezing, squirt
an approved de-icer fluid or glycerine
into the key opening. If a lock is covered
with ice, squirt it with an approved
de-icing fluid to remove the ice. If the
lock is frozen internally, you may be able
to thaw it out by using a heated key.
Handle the heated key with care to avoid
injury.
Use approved window washer anti-
freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types
of anti-freeze as these may damage the
paint finish.

7-54
Driving your vehicle
Don’t let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of snow
or ice around or near the rear brakes or
if the brakes are wet. If there is a risk
the parking brake may freeze, apply
it only temporarily while you put the
shift lever in N (for Automated Manual
Transmission) or in first or reverse gear
(for manual transmission) and block the
rear wheels so the vehicle cannot roll.
Then release the parking brake.
Don’t let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in severe winter conditions where this
may happen, you should periodically
check underneath the car to be sure the
movement of the front wheels and the
steering components is not obstructed.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropriate
emergency equipment. Some of the
items you may want to carry include tire
chains, tow straps or chains, flashlight,
emergency flares, sand, shovel, jumper
cables, window scraper, gloves, ground
cloth, coveralls, blanket, etc.
Don’t place foreign objects
or materials in the engine
compartment
Placement of foreign objects or
materials which prevent cooling of the
engine, in the engine compartment,
may cause a failure or combustion. The
manufacturer is not responsible for the
damage caused by such placement.
