Driving your vehicle
Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
kilometers (miles) you can get from a litre
(gallon) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-ate rate. Don't make "kangaroo" starts or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-tion. Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.
Take care of your tyres. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tyre
wear. Check the tyre pressures at leastonce a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting kerbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tyre wear and may
also result in other problems as well as
greater fuel consumption. Keep your car in good condition. For
better fuel economy and reduced
maintenance costs, maintain your carin accordance with the maintenance
schedule in section 7. If you drive your
car in severe conditions, more frequentmaintenance is required (see section 7
for details).
Keep your car clean. For maximum service, your vehicle should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel con-
sumption and also contribute to corro-sion.
Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel
economy.
Don't let the engine idle longer than necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.

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 tyres for proper
inflation before driving. For prop-
er tyre pressures, refer to “Tyres
and wheels” in section 8.
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
car. For further information and
tread limits, refer to “Tyres and
wheels” in section 7.

What to do in an emergency
If you have a tyre gauge, remove the
valve cap and check the air pressure.
If the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the cor-
rect pressure. If it is too high, adjust
it until it is correct. Always reinstall
the valve cap after checking or
adjusting tyre pressure. If the cap is
not replaced, air may leak from the
tyre. If you lose a valve cap, buyanother and install it as soon as pos-
sible.
After you have changed wheels,
always secure the flat tyre in its place
and return the jack and tools to their
proper storage locations.To prevent the jack, jack handle,
wheel brace and spare tyre from rat-
tling whilst the vehicle is in motion,
store them properly.CAUTION
Your vehicle has metric threads
on the wheel studs and nuts.Make certain during wheel removal that the same nuts thatwere removed are reinstalled -or, if replaced, that nuts withmetric threads and the same chamfer configuration are used.Installation of a non-metricthread nut on a metric stud or vice-versa will not secure thewheel to the hub properly andwill damage the stud so that it must be replaced.
Note that most nuts do not havemetric threads. Be sure to useextreme care in checking forthread style before installing aftermarket nuts or wheels. If indoubt, consult an authorisedHYUNDAI dealer.
WARNING - Wheel studs
If the studs are damaged, they
may lose their ability to retain
the wheel. This could lead to theloss of the wheel and a collisionresulting in serious injuries.
WARNING - Inadequate
spare tyre pressure
Check the inflation pressures as
soon as possible after installing
the spare tyre. Adjust it to the
specified pressure, if necessary.
Refer to “Tyres and wheels” sec-tion 8.

Important - use of compact spare
tyre (if equipped)
Your vehicle is equipped with a com-
pact spare tyre. This compact spare
tyre takes up less space than a reg-
ular-size tyre. This tyre is smaller
than a conventional tyre and is
designed for temporary use only.
The compact spare should be inflat-
ed to 420 kPa (60 psi).
✽✽NOTICE
Check the inflation pressure after
installing the spare tyre. Adjust it to
the specified pressure, as necessary.
When using a compact spare tyre,
observe the following precautions:
Under no circumstances should you exceed 80 km/h (50 mph); a higher speed could damage the
tyre.
Ensure that you drive slowly enough for the road conditions to
avoid all hazards. Any road hazard,
such as a pothole or debris, could
seriously damage the compact
spare.
Any continuous road use of this tyre could result in tyre failure, loss
of vehicle control, and possible
personal injury.
Do not exceed the vehicle’s maxi- mum load rating or the load-carry-
ing capacity shown on the sidewall
of the compact spare tyre.
Avoid driving over obstacles. The compact spare tyre diameter issmaller than the diameter of a con-
ventional tyre and reduces the
ground clearance approximately25 mm (1 inch), which could result
in damage to the vehicle.
CAUTION
You should drive carefully
when the compact spare is inuse. The compact spareshould be replaced by theproper conventional tyre and rim at the first opportunity.
The operation of this vehicle is not recommended withmore than one compact sparetyre in use at the same time.
WARNING
The compact spare tyre is for
emergency use only. Do not
operate your vehicle on this
compact spare at speeds over
80 km/h (50 mph). The originaltyre should be repaired or
replaced as soon as is possible
to avoid failure of the spare
possibly leading to personal
injury or death.

OWNER MAINTENANCE
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorised HYUNDAIdealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labour, parts and
lubricants used. Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in coolant reser-
voir.
Check the windscreen washer fluid level.
Look for low or under-inflated tyres.
WARNING - Maintenance
work
Performing maintenance work on a vehicle can be dangerous. You
can be seriously injured whilst
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorised HYUNDAI dealer.
Working under the bonnet with the engine running is dangerous.
It becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine whilst work-
ing under the bonnet, make cer-
tain that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and all
neckties, scarves, and similar
loose clothing before gettingnear the engine or cooling fans.
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns
or other serious injury.

Maintenance
Whilst operating your vehicle:
Note any changes in the sound of theexhaust or any smell of exhaust fumes
in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-aheadposition.
Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
elling 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 oper- ation of your transaxle occurs, check
the transaxle fluid level.
Check automatic transaxle P (Park) function.
Check parking brake.
Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-mal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
Check the inflation pressures of all tyres including the spare.
At least twice a year
(i.e., every Spring and Fall):
Check radiator, heater and air condi- tioning hoses for leaks or damage.
Check windscreen washer spray and wiper operation. Clean wiper blades
with clean cloth dampened with wash-er fluid.
Check headlight alignment.

CAUTION
Underinflation also results in
excessive wear, poor handlingand reduced fuel economy. Wheel deformation also ispossible. Keep your tyre pres-sures at the proper levels. If a tyre frequently needs refilling,have it checked by an autho-rised HYUNDAI dealer.
Overinflation produces a harsh ride, excessive wear atthe centre of the tyre tread,and a greater possibility ofdamage from road hazards.
TYRES AND WHEELS
Tyre care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tyre
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle. Recommended cold tyre inflation pressures All tyre pressures (including the
spare) should be checked when the
tyres are cold. “Cold Tyres” means
the vehicle has not been driven for at
least three hours or driven less than1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tyre
wear.
For recommended inflation pressure,
refer to “Tyre and wheels” in section8. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tyre underin-
flation
Severe underinflation can lead
to severe heat build-up, causing
blowouts, tread separation andother tyre failures that can
result in the loss of vehicle con-
trol leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.
