Driving your vehicle
If you believe your brakes may be
wet, apply them lightly whilst driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet.
The risk of hydroplaning increas-
es as the depth of tyre tread
decreases. Refer to "Tyre replace-
ment" in chapter 7.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times whilst the vehicle is mov-
ing slowly.
Highway driving
Tyres
Adjust the tyre inflation, as specified.
Under-inflation may overheat or
damage the tyres.
Do not install worn-out or damaged
tyres, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tyres above
the maximum inflation pressure, as
specified on your tyres.
Fuel, engine coolant and engine
oil
Driving at a high speed consumes
more fuel than driving at a slow
speed, such as in an urban area. Do
not forget to check both the engine
coolant and engine oil.
Drive belt
A loose or damaged drive belt may
overheat the engine.

Driving your vehicle
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:
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 tyresIf 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.
Information
Do not install studded tyres without
first checking local and municipal regu-
lations for possible restrictions against
their use.

Snow tyres should be equiva-
lent in size and type to the vehi-
cle's standard tyres. Otherwise,
the safety and handling of your
vehicle may be adversely affect-
ed.
WARNING

5-160
Driving your vehicle
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 shift lever in P (Park, for
automatic transmission/dual clutch
transmission vehicle) or N (Neutral,
for manual transmission vehicle).
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.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 war-
ranty.

What to do in an emergency
If the engine doesn't turn over
or turns over slowly
Be sure the shift lever is in N or
P(Neutral or Park, for automatic
transmission/dual clutch transmis-
sion 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.
If the engine turns over nor-
mally but doesn't start
Check the fuel level and add fuel if
necessary.
If the engine still does not start, we
recommend that you call an autho-
rised HYUNDAI dealer for assis-
tance.Jump starting can be dangerous if
done incorrectly. Follow the jump
starting procedure in this section to
avoid serious injury or damage to
your vehicle. If in doubt about how to
properly jump start your vehicle, we
strongly recommend that you have a
service technician or towing service
do it for you.
Push or pull starting the vehicle
may cause the catalytic con-
verter to overload which can
lead to damage to the emission
control system.

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 Engine
Start/Stop button is turned to
the ON 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
telltale
Low tyre pressure position
telltale and tyre pressure tell-
tale
When the tyre pressure monitoring
system warning indicators are illumi-
nated and the warning message dis-
played on the cluster LCD display,
one or more of your tyres is signifi-
cantly under-inflated. The low tyre
pressure position telltale light will
indicate which tyre is significantly
under-inflated by illuminating the cor-
responding position light.If either telltale illuminates, immedi-
ately reduce your speed, avoid hard
cornering and anticipate increased
stopping distances. You should stop
and check your tyres as soon as pos-
sible. Inflate the tyres to the proper
pressure as indicated on the vehi-
cle’s placard or tyre inflation pres-
sure label located on the driver’s side
centre pillar outer panel. If you can-
not reach a service station or if the
tyre cannot hold the newly added air,
replace the low pressure tyre with a
spare tyre.
If you drive the vehicle for about 10
minutes at speeds above 25 km/h
after replacing the low pressure tyre
with the spare tyre, the following will
happen:
The TPMS malfunction indicator
may blink for approximately 1
minute and then remain continu-
ously illuminated because the
TPMS sensor is not mounted on
the spare wheel.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check 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 posi-
tion.
Notice if your vehicle constantly
turns slightly or “pulls” to one side
when travelling on a smooth, level
road.
When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or a “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 transmis-
sion/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-pres-
sure 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 implemented with the artifi-
cial cardiac pacemaker, 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
electric engine control system
produce a considerable amount
of magnetic fields.
