Maintenance
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap iscorrectly replaced.
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold. Inspect the hose routing to assure that the hoses do not come in contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.Air cleaner filter
We recommend that you use air cleaner
filter for replacement from an authorized
HYUNDAI dealer.
Spark plugs (for gasoline engine)
Make sure to install new spark plugs of
the correct heat range. Cooling system
Check the cooling system parts, such as
radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts. Coolant The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transaxle fluid (if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
Automatic transaxle fluid (if equipped)
Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, we recommend
that the fluid be changed by an author-
ized HYUNDAI dealer in accordance tothe scheduled maintenance at the begin-
ning of this chapter.
✽✽
NOTICE
Automatic transaxle fluid color is basi-
cally red. As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.

ENGINE COOLANT
Changing the engine oil and filter
We recommend that the engine oil and
filter be replaced by an authorized
HYUNDAI dealer. The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant concentration level at least once
a year, at the beginning of the winter sea-
son, and before traveling to a colder cli-
mate.
Checking the coolant level
WARNING
Removing radiatorcap
 Never attempt to remove the radi- ator cap while the engine is oper-
ating or hot. Doing so might leadto cooling system and engine
damage and could result in seri-
ous personal injury from escap-ing hot coolant or steam.
 Turn the engine off and wait until it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop.
(Continued)
(Continued)Step back while the pressure is
released from the cooling sys-
tem. When you are sure all thepressure has been released,
press down on the cap, using a
thick towel, and continue turning
counterclockwise to remove it.
 Even if the engine is not operat- ing, do not remove the radiatorcap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.
WARNING
Used engine oil may cause irrita- tion or cancer of the skin if left in
contact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory ani-
mals. Always protect your skin by
washing your hands thoroughlywith soap and warm water as soon
as possible after handling used oil.

Maintenance
Check the condition and connections of all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks on
the side of the coolant reservoir when theengine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F (MAX), but do not overfill. If fre-
quent coolant refill is required, we rec-
ommend that the system be inspected by
an authorized HYUNDAI dealer.
Recommended engine coolant
 When adding coolant, use only deion-ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
 The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-ing.
 DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
 Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixture percentage, refer to the fol-
lowing table.

WARNING The electric motor (cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use extreme
caution when working near the
blades of the cooling fan so that
you are not injured by a rotating fan
blades. As the engine coolant tem-
perature decreases, the electric
motor will automatically shut off.This is a normal condition.
If your vehicle is equipped with
GDI, the electric motor (cooling fan)
may operate until you disconnect
the nagative battery cable.

Tyres:
Adjust the tyre inflation pressures to
specification. Low tyre inflation pressures
will result in overheating and possible
failure of the tyres.
Avoid using worn or damaged tyres
which may result in reduced traction or
tyre failure.
✽✽
NOTICE
Never exceed the maximum tyre infla-
tion pressure shown on the tyres.
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 tyres can cause poor handling,
loss of vehicle control, and sud-den tyre failure leading to acci-
dents, injuries, and even death.
Always check the tyres for proper
inflation before driving. For prop-
er tyre pressures, refer to section
8, “Tyres and wheels”.
 Driving on tyres with no or insuf- ficient tread is dangerous. Worn-out tyres can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tyresshould be replaced as soon as
possible and should never be
used for driving. Always check
the tyre tread before driving your
vehicle. For further information
and tread limits, refer to section

Driving your vehicle
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 the
maintenance schedule. Before winter,
have your coolant tested to assure that
its freezing point is sufficient for the tem-
peratures 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. We recommend that the system be
checked by a HYUNDAI authorised
repairer.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, we rec-
ommend that you consult a HYUNDAI
authorised repairer.
Check spark plugs and ignition system
Inspect your spark plugs 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.
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 them
hitting the vehicle.
WARNING - Tyre chains
 The use of chains may adversely affect vehicle handling.
 Do not exceed 20 mph (30 km/h) 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.

Maintenance
Changing the coolant
We recommend that the coolant be
replaced by a HYUNDAI authorised
repairer.Checking the brake/clutch fluid
level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir.
Before removing the reservoir cap and
adding brake/clutch fluid, clean the area
around the reservoir cap thoroughly to
prevent brake/clutch fluid contamination.
If the level is low, add fluid to the MAX
(Maximum) level. The level will fall with
accumulated mileage. This is a normal
condition associated with the wear of the
brake linings and/or clutch disc (ifequipped).If the fluid level is excessively low, we
recommend that the brake system be
checked by a HYUNDAI authorised
repairer.
Use only the specified brake/clutch fluid.
(Refer to “Recommended lubricants orcapacities” in section 8.)
Never mix different types of fluid.
WARNING - Loss of brake fluid
In the event the brake system
requires frequent additions of fluid,we recommend that the system be
inspected by a HYUNDAI autho-
rised repairer.
