Check spark plugs and ignition system
Inspect the spark plugs, as specified in
chapter 8. If necessary, replace them.
Also check all ignition wirings and
components for any cracks, wear-out,
and damage.
To prevent locks from freezing
To prevent the locks from being frozen,
spray approved de-icing fluid or glycerin
into key holes. When a lock opening is
already covered with ice, spray approved
de-icing fluid over the ice to remove it.
When an internal part of a lock freezes,
try to thaw it with a heated key. Carefully
use the heated key to avoid an injury.
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 specified
on the window washer container.
Window washer anti-freeze solution is
available from an authorized HYUNDAI
dealer, and most vehicle accessory
outlets. Do not 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
parking brake may freeze, temporarily
apply it with the gear 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 accumulate
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, to ensure
that the front wheels and the steering
components is unblocked.
Carry emergency equipment
In accordance with weather conditions,
you should carry appropriate emergency
equipment, while driving. 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.
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 they may
block the engine cooling. Such damage
will not be covered by the manufacturer’s
warranty.

NOTICE
To prevent engine and/or transmission
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.
• If you tow a trailer with the maximum
gross vehicle weight and maximum
trailer weight, it can cause the
engine or transmission to overheat.
When driving in such conditions,
allow the engine to idle until it cools
down. You may proceed once the
engine or transmission has cooled
sufficiently.
• When towing a trailer, your vehicle
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 vehicle speed according to the
maximum posted speed limit for
vehicles with trailers, the steepness
of the grade, and your trailer 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 space.
Turn the steering wheel in the
direction of the curb (right if headed
down hill, left if headed up hill).
2. Shift the gear 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.
5. Start the vehicle, hold the brakes, shift
to neutral, release the parking brake
and slowly release the brakes until the
trailer chocks absorb the load.
6. Reapply the brakes and parking
brakes.
7. Shift the gear to P (Park) when the
vehicle is parked on a uphill grade and
in R (Reverse) on a downhill.
8. Shut off the vehicle and release the
vehicle brakes but leave the parking
brake set.
WARNING
To prevent serious or fatal injury:
• Do not get out of the vehicle without
the parking brake firmly set. If you
have left the engine running, the
vehicle can move suddenly. You and
others could be seriously or fatally
injured.
• Do not apply the accelerator pedal to
hold the vehicle on an uphill.

Driving the vehicle after it has been
parked on a hill
1. With the gear in P (Park), apply your
brakes and hold the brake pedal down
while you:• Start your engine;
• Shift into gear; and
• Release the parking brake.
2. Slowly remove your foot from the
brake pedal.
3. Drive slowly until the trailer is clear of
the chocks.
4. Stop and have someone pick up and
store the chocks.
Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include engine oil,
transmission fluid, axle lubricant and
cooling system fluid. Brake condition
is another important item to frequently
check. If you’re trailering, it’s a good
idea to review these items before
you start your trip. Don’t forget to
also maintain your trailer and hitch.
Follow the maintenance schedule that
accompanied your trailer and check it
periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all hitch nuts and bolts
should be tight.
NOTICE
To prevent vehicle damage:
• Due to higher load during trailer
usage, overheating might occur on
hot days or during uphill driving.
If the coolant gauge indicates
over-heating, switch off the air
conditioner and stop the vehicle in a
safe area to cool down the engine.
• Do not switch off the engine while
the coolant gauge indicates over-
heating.
(Keep the engine idle to cool down
the engine)
• When towing check transmission
fluid more frequently.
• If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.

If your 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. Pull off the road and stop as soon as it
is safe to do so.
2. Shift the gear to P (Park) 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
not open 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
operating. If the fan is not running,
turn the engine off.
WARNING
While the engine is running, keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury.
4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out, stop
the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance.
WARNING
Never remove the engine coolant cap and/or water-
cooled intercooler coolant
cap or the drain 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 removing the coolant cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back while the pressure is
released from the cooling system. When
you are sure all the pressure has been
released, press down on the cap, using
a thick towel, and continue turning
counterclockwise to remove it.
IF THE ENGINE OVERHEATS

Emergency situations
8-8
6. If you cannot find the cause of the
overheating, wait until the engine
temperature 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 overheating happens again,
we recommend that you call an
authorized HYUNDAI dealer for
assistance.
CAUTION
• Serious loss of coolant indicates a
leak in the cooling system and we
recommend the system be checked
by an authorized HYUNDAI dealer.
• When the engine overheats from
low engine coolant, suddenly adding
engine coolant may cause cracks
in the engine. To prevent damage,
add engine coolant slowly in small
quantities. It may require several
refilling cycles to properly fill the
engine cooling system. If necessary,
an authorized HYUNDAI dealer
should be consulted to perform this
task.

Owner maintenance schedule
When you stop for fuel:
• Check the coolant level in the engine
coolant reservoir.
• Check the windshield washer fluid
level.
• Check for low or under-inflated tires.
WARNING
Be careful when checking your coolant
level when the engine is hot. This may
result in coolant being blown out of the
opening and cause serious burns and
other injuries.
While operating your vehicle:
• Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
• Check for vibrations in the steering
wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.
• Notice if your vehicle constantly turns
slightly or “pulls” to one side when
traveling on smooth, level road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the
operation of your transmission occurs,
check the transmission fluid level.
• Check the automatic transmission P
(Park) function.
• Check the parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
• Check coolant level in the engine
coolant reservoir.
• Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all
tires including the spare for tires that
are worn, show uneven wear, or are
damaged.
• Check for loose wheel lug nuts.
At least twice a year:
• Check radiator, heater and air
conditioning hoses for leaks or
damage.
• Check windshield washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.
• Check headlamp alignment.
• Check muffler, exhaust pipes, shields
and clamps.
• Check the seat belts for wear and
function.
At least once a year:
• Clean body and door drain holes.
• Lubricate door hinges and hood
hinges.
• Lubricate door and hood locks and
latches.
• Lubricate door rubber weather strips.
• Check the air conditioning system.
• Inspect and lubricate automatic
transmission linkage and controls.
• Clean the battery and terminals.
• Check the brake fluid level.
