Features of your vehicle
Tachometer
The tachometer indicates the approxi-
mate number of engine revolutions per
minute (rpm). Use the tachometer to select the correct
shift points and to prevent lugging and/or
over-revving the engine.
When the door is open, or if the engine is
not started within 1 minute, the tachometer
pointer may move slightly in ON position
with the engine OFF. This movement is
normal and will not affect the accuracy of
the tachometer once the engine is running.
Engine temperature gauge
This gauge shows the temperature of the engine coolant when the engine
start/stop button is ON.
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “If the engine overheats” in section 6.
CAUTION
If the gauge pointer moves beyondthe normal range area toward the“H” position, it indicates overheat-
ing that may damage the engine.
CAUTION
Do not operate the engine withinthe tachometer's RED ZONE. This may cause severe engine damage.
WARNING
Never remove the radiator cap
when the engine is hot. The enginecoolant is under pressure and
could cause severe burns. Wait
until the engine is cool before
adding coolant to the reservoir.

Driving your vehicle
Before entering vehicle
• Be sure that all windows, outside mir-ror(s), and outside lights are clean.
Check the condition of the tires.
Check under the vehicle for any sign of leaks.
Be sure there are no obstacles behind you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil, engine
coolant, brake fluid, and washer fluid
should be checked on a regular basis,
with the exact interval depending on the
fluid. Further details are provided in sec-
tion 7, “Maintenance”. Before starting
Close and lock all doors.
Position the seat so that all controls are
easily reached.
Adjust the inside and outside rearview mirrors.
Be sure that all lights work.
Check all gauges.
Check the operation of warning lights when the engine start/stop button is
turned to the ON position.
Release the parking brake and make sure the brake warning light goes out.
For safe operation, be sure you are famil-
iar with your vehicle and its equipment.
BEFORE DRIVING
WARNING
All passengers must be properly
belted whenever the vehicle is mov-
ing. Refer to “Seat belts” in section
3 for more information on their
proper use.
WARNING
Always check the surrounding
areas near your vehicle for people,
especially children, before putting a
vehicle into D (Drive) or R
(Reverse).
WARNING
When you intend to park or stop the
vehicle with the engine on, be care-ful not to depress the accelerator
pedal for a long period of time. It
may overheat the engine or exhaust
system and cause fire.
WARNING - Driving under
the influence of alcohol or drugs
Drinking and driving is dangerous.
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. Drivingwhile under the influence of drugs
is as dangerous or more dangerousthan driving drunk.
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 driv-er who has been drinking or taking
drugs. Choose a designated driveror call a cab.

Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
✽✽NOTICE
Never exceed the maximum tire inflation
pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engineoil.
Drive belt
A loose or damaged drive belt may result
in overheating of the engine.
WARNING
Underinflated or overinflated tires can cause poor handling,
loss of vehicle control, and sud-den tire failure leading to acci-
dents, injuries, and even death.
Always check tires for proper
inflation before driving. For prop-
er tire pressures, refer to “Tires
and wheels” in section 8.
Driving on tires with no or insuffi- cient tread is dangerous. Worn-out tires can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tiresshould be replaced as soon as
possible and should never be
used for driving. Always check
the tire tread before driving your
car. For further information and
tread limits, refer to “Tires and
wheels” in section 7.

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, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with themaintenance schedule in section 7.
Before winter, have your coolant tested toassure 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 bat-
tery and cables as described in section
7. 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 section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check spark plugs and ignition system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING
- Tire chains
The use of chains may adversely affect vehicle handling.
Do not exceed 30 km/h (20 mph) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked- wheel braking.
CAUTION
Chains that are the wrong size or
improperly installed can damage
your vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

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 con-
tainer. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Donot use engine coolant or other types of
anti-freeze as these may damage thepaint finish.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 temporar-
ily while you put the gear shift lever in P
and block the rear wheels so the vehicle
cannot roll. Then release the parking
brake.
Don't let ice and snow accumu- late underneath
Under some conditions, snow and ice
can build up under the fenders and inter-
fere with the steering. When driving in
severe winter conditions where this may
happen, you should periodically check
underneath the car to be sure the move-
ment of the front wheels and the steering
components is not obstructed.Carry emergency equipment
Depending on the severity of the weath-
er, you should carry appropriate emer-
gency equipment. Some of the items you
may want to carry include tire chains, tow
straps or chains, flashlight, emergency
flares, sand, a shovel, jumper cables, a
window scraper, gloves, ground cloth,
coveralls, a blanket, etc.

IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the shift lever in P and set the parking brake. If the air conditioning is
on, turn it off.
3. If engine coolant is running out under the vehicle or steam is coming out
from the hood, stop the engine. Do notopen the hood until the coolant has
stopped running or the steaming has
stopped. If there is no visible loss of
engine coolant and no steam, leave
the engine running and check to be
sure the engine cooling fan is operat-
ing. If the fan is not running, turn the
engine off. 4. Check to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from
it when you stop).
5. If the water pump drive belt is broken or engine coolant is leaking out, stop the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance. 6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-heating happens again, call an author-
ized HYUNDAI dealer for assistance.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
CAUTION
Serious loss of coolant indicates there is a leak in the cooling systemand this should be checked as soonas possible by an authorized HYUNDAI dealer.
