The severe weather conditions of
winter quickly wear out tyres and
cause other problems. To minimise
winter driving problems, you should
take the following suggestions:
Information
Summer tyres are equipped to provide
the best driving performance on dry
roads, varying according to specifica-
tion. Since vehicles equipped with
summer tires significantly reduce sur-
face forces when driving on snow or
ice roads, it is recommended to use
snow tyres of the same size as the stan-
dard tyres of the vehicle or the replace
them with all seasons tires or to use
chains.
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 skids to occur.
To drive your vehicle in deep snow, it
may be necessary to use snow tyres
or to install tyre chains on your tyres.
Always carry emergency equipment.
Some of the items you may want to
carry include tyre chains, tow straps
or chains, a flashlight, emergency
flares, sand, a shovel, jumper cables,
a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tyres
We recommend you use snow tyres
when road temperature is below 7°C
(45°F).
If you mount snow tyres on your vehi-
cle, make sure to use radial tyres of
the same size and load range as the
original tyres. Mount snow tyres on
all four wheels to balance your vehi-
cle’s handling in all weather condi-
tions. The traction provided by snow
tyres on dry roads may not be as
high as your vehicle's original equip-
ment tyres. Check with the tyre deal-
er for maximum speed recommenda-
tions.

Snow tyres should be equivalent
in size and type to the vehicle's
standard tyres. Otherwise, the
safety and handling of your vehi-
cle may be adversely affected.
WARNING
Using summer tyres at very
cold temperature could cause
cracks on them to be formed
and damage them permanently.

Use approved window washer
anti-freeze solution in system
To prevent the window washer from
being frozen, add authorised window
washer anti-freeze solution, as spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorised
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 hap-
pen 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 wheel
arches and interfere with the steer-
ing. When driving in such conditions
during a severe winter, you should
check underneath the vehicle on a
regular basis, to ensure that the front
wheels and steering components are
unblocked.
Carry emergency equipment
In accordance with weather condi-
tions, you should carry appropriate
emergency equipment, whilst driv-
ing. Some of the items you may want
to carry include tyre chains, tow
straps or chains, flashlight, emer-
gency flares, sand, shovel, jumper
cables, window scraper, gloves,
ground cloth, coveralls, blanket, etc.

What to do in an emergency
If you have a flat tyre whilst
driving
If a tyre goes flat whilst you are driv-
ing:
Take your foot off the accelerator
pedal and let the vehicle slow
down whilst driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause loss of vehicle
control 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,
for automatic transmission/dual
clutch transmission vehicle) or neu-
tral (for manual transmission vehi-
cle), apply the parking brake, and
place the ignition switch in the
LOCK/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 tyre, follow
the instructions provided later in
this chapter.If the engine doesn't turn over
or turns over slowly
Be sure the shift lever is in N
(Neutral) or P (Park) if it is an auto-
matic transmission/dual clutch
transmission vehicle. The engine
starts only when the shift lever is in
N (Neutral) or 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.

What to do in an emergency
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tyre pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the system
may not be able to detect or signal
low tyre pressure as intended.
TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or alter-
nate tyres or wheels on the vehicle
that prevent the TPMS from function-
ing properly. Always check the TPMS
malfunction telltale after replacing
one or more tyres or wheels on your
vehicle to ensure that the replace-
ment or alternate tyres and wheels
allow the TPMS to continue to func-
tion properly.If any of the below happens, we
recommend that the system be
checked by an authorised HYUNDAI
dealer.
1. The low tyre pressure telltale/
TPMS malfunction indicator
does not illuminate for 3 sec-
onds when the ignition switch is
turned to the ON position or the
engine is running.
2. The TPMS malfunction indicator
remains illuminated after blink-
ing for approximately 1 minute.
3. The Low tyre pressure position
telltale remains illuminated.
Low tyre pressure

Low tyre pressure
position telltale
and tyre pressure

When the tyre pressure monitoring
system warning indicators are illumi-
nated and a warning message is dis-
played on the cluster LCD display,
one or more of your tyres is signifi-
cantly under-inflated. The low tyre
pressure position telltale will indicate
which tyre is significantly under-
inflated by illuminating the corre-
sponding position light.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windscreen washer fluid
level.
Check for low or under-inflated
tyres.
Whilst 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
travelling 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 transmissiom
occurs, check the transmissiom 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 whilst 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
high pressure immediately after
stopping the diesel engine.
When the fuel leakage vents out,
it may cause serious body injury.
Any people, who are implanted
with the artificial cardiac pace-
maker, should remain away from
the ECU or the wiring harness by
at least 30 cm, whilst running the
diesel engine. The high currents
of the electronic engine control
system produce a considerable
amount of magnetic fields.
WARNING

7-8
Maintenance
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
tyres including the spare for tyres
that are worn, show uneven wear,
or are damaged.
Check for loose wheel nuts.
At least twice a year:
(i.e., every Spring and Autumn)
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windscreen washer spray
and wiper operation. Clean wiper
blades with a clean cloth damp-
ened 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 bonnet
hinges.
Lubricate door and bonnet 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.

Draining water from fuel filter
The fuel filter in the diesel engine
operates the critical function of sepa-
rating water from the fuels and pre-
venting accumulating of water in the
base.
When enough water has accumulat-
ed inside the fuel filter, the warning
light ( ) illuminates with the igni-
tion switch in the ON position.
In this case, we recommend you to
have the system checked by an
authorised HYUNDAI dealer.
When the accumulated water is not
drained at the proper timing, water
may permeate in the fuel filter,
damaging the major vehicle com-
ponents, such as the fuel system.
Fuel filter cartridge replace-
ment
We recommend the fuel filter car-
tridge be replaced by an authorised
HYUNDAI dealer according to the
Maintenance Schedule at the begin-
ning of this chapter.
Filter replacement
The air cleaner filter can be cleaned
for inspection using compressed air.
Do not attempt to wash or to rinse it,
as water will damage the filter.
If soiled, the air cleaner filter must be
replaced.NOTICE
