Chain Installation
When installing tire chains, follow the
manufacturer's instructions and
mount them as tightly possible. Drive
slowly (less than 30 km/h (20 mph))
with chains installed. If you hear the
chains contacting the body or chas-
sis, stop and tighten them. If they still
make contact, slow down until the
noise stops. Remove the tire chains
as soon as you begin driving on
cleared roads.
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning Flasher and place a
triangular emergency warning device
behind the vehicle (if available).
Always place the vehicle in P (Park),
apply the parking brake and turn off
the engine before installing snow
chains.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, retight- en the chains after driving 0.5~1.0
km (0.3~0.6 miles).
Do not use tire chains on vehi- cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 12 mm (0.47 in) wide to prevent damage
to the chain’s connection.
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 section 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.

Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transmission fluid, axle lubri-
cant 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 sched-
ule that accompanied your trailer and
check it periodically. Preferably, con-
duct the check at the start of each
day’s driving. Most importantly, all
hitch nuts and bolts should be tight.To prevent vehicle damage:
Due to higher load during trailer
usage, overheating might occur
on hot days or during uphill driv-
ing. If the coolant gauge indi-
cates 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 indi-
cates over-heating.
(Keep the engine idle to cool
down the engine)
When towing check automatic transmission fluid more fre-
quently.
If your vehicle is not equipped with an air conditioner, you
should install a condenser fan
to improve engine performance
when towing a trailer.

Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires.
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 loose-
ness 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 transaxle occurs,
check the transaxle fluid level.
Check the automatic transmission/ dual clutch 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).
Be careful when checking your
engine 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.
WARNING
Diesel Engine
Never manipulate or modify the
injection system while running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
the high pressure right after
stopping the diesel engine.
When the fuel leakage vents out,
it may cause serious body injury.
Any people, who are implement-
ed with the artificial cardiac
pacemaker, should remain away
from the ECU or the wiring har-
ness by at least 30 cm, while run-
ning the diesel engine. The high
currents of the electric engine
control system produce a con-
siderable amount of magnetic
fields.
WARNING

Maintenance
At least monthly:
Check coolant level in the enginecoolant 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: (i.e., every Spring and Fall)
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windshield washer spray and wiper operation. Clean wiper
blades with 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 hoodhinges.
Lubricate door and hood locks and latches.
Lubricate door rubber weather strips.
Check the air conditioning system.
Inspect and lubricate automatic transaxle linkage and controls.
Clean the battery and terminals.
Check the brake fluid level.

lem etc, replace the fuel filter immediately regardless of maintenance schedule and consult an authorized HYUNDAI dealer for
details.
