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
The severe weather conditions of
winter quickly wear out tires and
cause other problems. To minimize
winter driving problems, you should
take the following suggestions:
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 the vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires
on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tow straps or chains, a
flashlight, emergency flares, sand, a
shovel, jumper cables, a window
scraper, gloves, ground cloth, cover-
alls, a blanket, etc.
Snow tiresIf you mount snow tires on your vehi-
cle, 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.Information
Do not install studded tires without
first checking local, country and
municipal regulations for possible
restrictions against their use.
i
WW IINN TTEERR DD RRIIVV IINN GG
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 affect-ed.
WARNING

Driving your vehicle
Use approved window washer
anti-freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorized
HYUNDAI dealer, and so are the
most vehicle accessory outlets. Donot use engine coolant or other types
of anti-freeze solution to prevent any
damage to the vehicle paint.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.
When there is the risk that your park-
ing brake may freeze, temporarily
apply it with the shift lever in P
(Park). Also, block the rear wheels in
advance, so the vehicle may not roll.
Then, release the parking brake.
Do not let ice and snow accumu- late underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in such conditions during the
severe winter, you should check
underneath the vehicle on a regular
basis, so that moving the front
wheels and the steering components
is unblocked.Carry emergency equipment
In accordance with weather condi-
tions, you should carry appropriate
emergency equipment, while driving.
Some of the items you may want to
carry include tow straps or chains,
flashlight, emergency flares, sand,
shovel, jumper cables, window
scraper, gloves, ground cloth, cover-
alls, blanket, etc. Do not place objects or materials
in the engine compartment
Putting objects or materials in the
engine compartment may cause an
engine failure or combustion,
because those may block the engine
cooling. Such damage will not be
covered by the manufacturer’s war-
ranty.

What to do in an emergency
If you have a flat tire while driving
If a tire goes flat while you are driving:
Take your foot off the acceleratorpedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-ately or attempt to pull off the road
as this may cause loss of vehiclecontrol resulting in an accident.
When the vehicle has slowed to
such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes.
When the vehicle is stopped, press the hazard warning flasher button,
move the shift lever into P(Park),
and apply the parking brake, and
place the Engine Start/Stop buttonin the OFF position.
Have all passengers get out of the vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
When changing a flat tire, follow the instructions provided later in
this chapter. Be sure the shift lever is in P
(Park). The vehicle starts only
when the shift lever is in P (Park).
Check the battery connections to be sure they are clean and tight.
Turn on the interior light. If the light dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle. See instructions for
"Jump Starting" provided in this
chapter.
If the engine turns over nor-
mally but doesn't start
Check the fuel level and add fuel if
necessary.
If the engine still does not start, have
your vehicle checked by an author-
ized HYUNDAI dealer.

4. Connect the jumper cables in theexact sequence shown in the illus-
tration. First connect one jumper
cable to the red, positive (+)
jumper terminal of your vehicle(1). 5. Connect the other end of the
jumper cable to the red, positive
(+) battery/jumper terminal of the
assisting vehicle (2).
6. Connect the second jumper cable to the black, negative (-) battery/
chassis ground of the assisting
vehicle (3).
7. Connect the other end of the sec- ond jumper cable to the black,
negative (-) chassis ground of
your vehicle (4).
Do not allow the jumper cables to
contact anything except the cor-
rect battery or jumper terminals or
the correct ground. Do not lean
over the battery when making
connections.
8. Start the engine of the assisting vehicle and let it run at approxi-
mately 2,000 rpm for a few min-
utes. Then start your vehicle.
If your vehicle will not start after a
few attempts, it probably requires
servicing. In this event please seek
qualified assistance. If the cause of
your battery discharging is not
apparent, have your vehicle checked
by an authorized HYUNDAI dealer. Disconnect the jumper cables in the
exact reverse order you connectedthem:
1. Disconnect the jumper cable from
the black, negative (-) chassis
ground of your vehicle (4).
2. Disconnect the other end of the jumper cable from the black, neg-
ative (-) battery/chassis ground of
the assisting vehicle (3).
3. Disconnect the second jumper cable from the red, positive (+)
battery/jumper terminal of the
assisting vehicle (2).
4. Disconnect the other end of the jumper cable from the red, positive
(+) jumper terminal of your vehicle(1).

If your engine coolant temperature
gauge indicates overheating, you
experience a loss of power, or hear
loud pinging or knocking, the engine
may be overheating. If this happens,
you should:
1. Turn ON the hazard warning flash-er, pull off the road and stop as
soon as it is safe to do so.
2. Place the shift lever in P (Park) and set the parking brake.
3. Make sure that there is no hotsteam gushing out of the engine
compartment. When it is safe to
do so, open the engine compart-
ment, and check the water-pump
connector. When the water-pumpconnector is disconnected, stop
the engine, re-connect the water-
pump connector, and then re-start
the engine.
4. Set the temperature and the air flow to the maximum, and turn ON
the air conditioner. 5. When the Service warning light
( ) illuminates on the instru-
ment cluster, immediately stop the
engine, and contact an authorized
HYUNDAI dealer. When the
engine warning light ( ) illumi-
nates, or when the coolant or hotsteams gush out of the engine
compartment, leave the engine
compartment opened, while run-
ning the engine. This is to ventilate
the engine compartment and to
cool down the engine.
6. Check the coolant temperature gauge on the instrument cluster to
make sure the coolant temperature
is sufficiently cooled down. Check
the coolant level. When it is insuffi-
cient, check its connection with the
radiator, the heater hose, and the
water pump for any leakage. When
there is no leakage, add the
coolant. However, if the problems
persists, such as the illumination of
the warning lights, leakages, or the
cooling-fan malfunction, which may
overheat the engine, immediately
stop the engine, and have your
vehicle checked by an authorized
HYUNDAI dealer.

7. If you cannot find the cause of theoverheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has beenlost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
8. Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
Serious loss of coolant indi-cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
The electric motor for
the cooling fan may
continue to operate
or start up when theengine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
WARNING
Your vehicle is equipped with a pres-
surized coolant
reserve tank. NEVER
remove the coolant
reserve tank cap or the radiatordrain plug while the engine and
radiator are HOT. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the coolant reserve tank
cap. Wrap a towel or thick rag
around it, and turn it counter-
clockwise slowly to release
some of the pressure from the
system. Step back while thepressure is released.
When you are sure all the pres-
sure has been released, contin-ue turning the cap counter-
clockwise to remove it.

When the tire pressure monitoring
system warning indicators are illumi-
nated and warning message dis-
played on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The Low Tire
Pressure Position Telltale will indi-cate which tire is significantly under-
inflated by illuminating the corre-sponding position light.
If either telltale illuminates, immedi-
ately reduce your speed, avoid hard
cornering and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-cle's placard or tire inflation pressure
label located on the driver's side cen-ter pillar outer panel. If you cannot reach a service station
or if the tire cannot hold the newly
added air, replace the low pressure
tire with the spare tire.
The Low Tire Pressure Telltale will
remain on and the TPMS Malfunction
Indicator may blink for one minuteand then remain illuminated (when
the vehicle is driven approximately
20 minutes at speed above 25 km/h
(15.5 mph)) until you have the lowpressure tire repaired and replaced
on the vehicle.
Information
The spare tire is not equipped with a
tire pressure sensor.
