Gauges and Meters
Speedometer
The speedometer indicates the
speed of the vehicle and is calibrated
in miles per hour (mph) and/or kilo-
meters per hour (km/h).
Tachometer
The tachometer indicates the
approximate number of engine revo-
lutions per minute (rpm).
Use the tachometer to select the cor-
rect shift points and to prevent lug-
ging and/or over-revving the engine.
Do not operate the engine within
the tachometer's RED ZONE. This
may cause severe engine damage.

Convenient features of your vehicle
If the gauge pointer moves
beyond the normal range area
toward the "H" position, it indi-
cates overheating that may dam-
age the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to "If the Engine
Overheats" in chapter 6.
Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
Information
• The fuel tank capacity is given in
chapter 8.
• The fuel gauge is supplemented by a
low fuel warning light, which will
illuminate when the fuel tank is
nearly empty.
• On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier
than usual due to the movement of
fuel in the tank.Avoid driving with an extremely
low fuel level. Running out of fuel
could cause the engine to misfire,
damaging the catalytic converter.
NOTICE

NOTICE
Running out of fuel can expose
vehicle occupants to danger. You
must stop and obtain additional
fuel as soon as possible after
the warning light comes on or
when the gauge indicator comes
close to the "E (Empty)" level.
WARNING
Never remove the radiator cap
or engine coolant reservoir cap
when the engine is hot. The
engine coolant is under pres-
sure and could severely burn.
Wait until the engine is cool
before adding coolant to the
reservoir.

Low Pressure
This warning message is displayed if
the tire pressure is low. The corre-
sponding tire on the vehicle will be
illuminated.
For more details, refer to "Tire
Pressure Monitoring System
(TPMS)" in chapter 6.
Low washer fluid
This warning message is displayed
on the service reminder mode if the
washer fluid level in the reservoir is
nearly empty.
If this warning message is displayed,
have the washer fluid reservoir
refilled.
Low fuel
This warning message is displayed if
the fuel tank is almost out of fuel.
When this message is displayed, the
vehicle range is approximately 30
miles (50 km).
When this message is displayed, the
low fuel level warning light in the
cluster will come on.
It is recommended to look for the
nearest fueling station and refuel as
soon as possible.
Add fuel as soon as possible.
Engine overheated
This warning message is displayed
with a warning chime when the
engine coolant temperature is above
248°F (120°C). This means that the
engine is overheated and may be
damaged.
If your vehicle is overheated, refer
to "Overheating" in chapter 6.

Driving your vehicle
If you believe your brakes may be
wet, apply them lightly while driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet.
The risk of hydroplaning increases
as the depth of tire tread decreas-
es, refer to "Tire replacement" in
chapter 7.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Highway driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or
damage the tires.
Do not install worn-out or damaged
tires, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Fuel, engine coolant and engine
oil
Driving at higher speeds on the high-
way consumes more fuel and is less
efficient than driving at a slower,
more moderate speed. Maintain a
moderate speed in order to conserve
fuel when driving on the highway.
Be sure to check both the engine
coolant level and the engine oil
before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

Driving your vehicle
- When using tire chains:
Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Use SAE "S" class or wire
chains.
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).
Do not use tire chains on vehi-
cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 0.59
inch (15 mm) wide to prevent
damage to the chain’s connec-
tion.
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 cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. 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 7. 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 7 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.
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 instruc-
tions on the container. Window wash-
er 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.
Do not 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 gear selector lever in P
and block the rear wheels so the car
cannot roll. Then release the parking
brake.
Do not let ice and snow accu-
mulate 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 com-
ponents is not obstructed.
Don't place foreign objects or
materials in the engine com-
partment
Placement of foreign object or mate-
rials 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.
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 heat-
ed key with care to avoid injury.

Driving on hills
Reduce speed and shift to a lower
gear before you start down a long or
steep downgrade. If you don't shift
down, you might have to use your
brakes so much that they would get
overheated and may not operate effi-
ciently.
On a long uphill grade, shift down
and reduce your speed to around 45
mph (70 km/h) to reduce the possibil-
ity of engine and transmission over-
heating.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes, you should drive in D (Drive)
when towing a trailer. Operating your
vehicle in D (Drive) when towing a
trailer will minimize heat build-up and
extend the life of your transmission.To prevent engine and/or trans-
mission overheating:
When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the engine
coolant temperature gauge to
ensure the engine does not
overheat. If the needle of the
coolant temperature gauge
moves towards "H" (HOT), pull
over and stop as soon as it is
safe to do so, and allow the
engine to idle until it cools
down. You may proceed once the
engine has cooled sufficiently.
When towing a trailer, your vehi-
cle speed may be much slower
than the general flow of traffic,
especially when climbing an
uphill grade. Use the right hand
lane when towing a trailer on an
uphill grade. Choose your vehi-
cle speed according to the max-
imum posted speed limit for
vehicles with trailers, the steep-
ness of the grade, and your trail-
er weight.
Parking on hills
Generally, if you have a trailer attached
to your vehicle, you should not park
your vehicle on a hill.
However, if you ever have to park your
trailer on a hill, here's how to do it:
1. Pull the vehicle into the parking
area.
Turn the steering wheel in the
direction of the curb (right if head-
ed down hill, left if headed up hill).
2. Shift the vehicle to P (Park).
3. Set the parking brake and shut off
the vehicle.
4. Place wheel chocks under the
trailer wheels on the down hill side
of the wheels.
