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 Tread" 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
adversely affect vehicle handling and
braking.
Information
Never over-inflate your tyres above
the maximum inflation pressure, as
specified on your tyres.
Fuel, engine coolant and engine
oil
Driving at higher speeds on the high-
way consumes more fuel and is less
efficient than driving at a slower,
more moderate speed. Maintain a
moderate speed in order to conserve
fuel when driving on the highway.
Be sure to check both the engine
coolant level and the engine oil
before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

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.

Driving your vehicle
Driving on hills
Reduce speed and shift to a lower
gear before you start down a long or
steep downgrade. If you don’t shift
down, you might have to use your
brakes so much that they would get
overheated and may not operate effi-
ciently.
On a long uphill grade, shift down
and reduce your speed to around 70
km/h to reduce the possibility of
engine and transmission overheat-
ing.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes and you have an automat-
ic transmission/dual clutch transmis-
sion, you should drive in D (Drive)
when towing a trailer.
Operating your vehicle in D (Drive)
when towing a trailer will minimise
heat build-up and extend the life of
your transmission.To prevent engine and/or trans-
mission overheating:
When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the engine
coolant temperature gauge to
ensure the engine does not
overheat. If the needle of the
coolant temperature gauge
moves towards "H" (HOT), pull
over and stop as soon as it is
safe to do so, and allow the
engine to idle until it cools
down. You may proceed once the
engine has cooled sufficiently.
If you tow a trailer with the max-
imum gross vehicle weight and
maximum trailer weight, it can
cause the engine or transmis-
sion to overheat. When driving
in such conditions, allow the
engine to idle until it cools
down. You may proceed once the
engine or transmission has
cooled sufficiently.
(Continued)(Continued)
When towing a trailer, your vehi-
cle speed may be much slower
than the general flow of traffic,
especially when climbing an
uphill grade. Use the left hand
lane when towing a trailer on an
uphill grade. Choose your vehi-
cle speed according to the max-
imum posted speed limit for
vehicles with trailers, the steep-
ness of the grade, and your trail-
er weight.
Vehicles equipped with a dual
clutch transmission when tow-
ing a trailer on steep grades,
need to be aware that the clutch
in the transmission could over-
heat.
When the clutch is overheated,
the safe protection mode
engages. If the safe protection
mode engages, the gear posi-
tion indicator on the cluster
blinks with a chime sound.

Driving your vehicle
Ready to leave after parking on
a hill
1. With the shift lever in P (Park, for
automatic transmission/dual clutch
transmission vehicle) or neutral (for
manual transmission vehicle),
apply your brakes and hold the
brake pedal down whilst you:

and

2. Slowly remove your foot from the
brake pedal.
3. Drive slowly until the trailer is clear
of the chocks.
4. Stop and have someone pick up
and store the chocks.
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 towing, it’s
a good idea to review these items
before you start your trip. Don’t forget
to also maintain your trailer and tow-
bar. 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
towbar 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
whilst 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.

What to do in an emergency
6
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1. Pull off the road and stop as soon
as it is safe to do so.
2. Place the shift lever in P (Park, for
automatic transmission/dual clutch
transmission vehicle) or neutral (for
manual transmission/dual clutch
transmission vehicle) and set the
parking brake. If the air condition-
ing is ON, turn it OFF.
3. If engine coolant is running out
under the vehicle or steam is com-
ing out from the bonnet, stop the
engine. Do not open the bonnet
until the coolant has stopped run-
ning or the steaming has stopped.
If there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be
sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had been
in use, it is normal for cold water to
be draining from it when you stop.)
5. If engine coolant is leaking out, stop
the engine immediately and we rec-
ommend that you call an authorised
HYUNDAI dealer for assistance.

Whilst the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING
NEVER remove the
radiator cap or the
drain plug whilst the
engine and radiator
are hot. Hot coolant
and steam may blow out under
pressure, causing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator cap. Wrap a
thick towel around it, and turn it
anticlockwise slowly to the first
stop. Step back whilst the pres-
sure is released from the cool-
ing system. When you are sure
all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning anticlockwise
to remove it.

What to do in an emergency
6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
7. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call an
authorised HYUNDAI dealer for
assistance.

TPMS Malfunction Indicator
(2) Low Tyre Pressure Position
Telltale and Tyre Pressure
Telltale (Shown on the LCD dis-
play)
Check tyre pressure
You can check the tyre pressure in
the Assist mode on the cluster.
Refer to the "LCD Display
Modes" in chapter 3.
Tyre pressure is displayed after a
few minutes of driving after initial
engine start up.
If tyre pressure is not displayed when
the vehicle is stopped, "Drive to dis-
play" message will appear. After driv-
ing, check the tyre pressure.
Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked by an
authorised HYUNDAI dealer.
When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
