Fuel, engine coolant and engine oil:
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engine
oil.
Drive belt:
A loose or damaged drive belt may result
in overheating of the engine.
Reducing the risk of a rollover
This multi-purpose passenger vehicle is
defined as a Sports Utility Vehicle (SUV).
SUV’s have higher ground clearance
and a narrower track to make them capa-
ble of performing in a wide variety of off-
road applications. Specific design char-
acteristics give them a higher centre of
gravity than ordinary cars. An advantage
of the higher ground clearance is a better
view of the road, which allows you to
anticipate problems. They are not
designed for cornering at the same
speeds as conventional passenger drive
vehicles, any more than low-slung sports
cars are designed to perform satisfactori-
ly in off-road conditions. Due to this risk,
driver and passengers are strongly rec-
ommended to buckle their seat belts. In
a rollover crash, an unbelted person is
more likely to die than a person wearing
a seat belt. There are steps that a driver
can make to reduce the risk of a rollover.
If at all possible, avoid sharp turns or
abrupt manoeuvres, do not load your
roof rack with heavy cargo, and never
modify your vehicle in any way.WARNING - Rollover
As with other Sports Utility Vehicle
(SUV), failure to operate this vehi-
cle correctly may result in loss of
control, an accident or vehicle
rollover.
• Utility vehicles have a significant-
ly higher rollover rate than other
types of vehicles.
• Specific design characteristics
(higher ground clearance, nar-
rower track, etc.) give this vehicle
a higher centre of gravity than
ordinary cars.
• A SUV is not designed for corner-
ing at the same speeds as con-
ventional vehicles.
• Avoid sharp turns or abrupt
manoeuvres.
• In a rollover crash, an unbelted
person is significantly more like-
ly to die than a person wearing a
seat belt. Make sure everyone in
the vehicle is properly buckled
up.

Turn signals when towing a trailer
When you tow a trailer, your vehicle has
to have a different turn signal flasher and
extra wiring. The green arrows on your
instrument panel will flash whenever you
signal a turn or lane change. Properly
connected, the trailer lights will also flash
to alert other drivers you’re about to turn,
change lanes, or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think drivers
behind you are seeing your signals
when, in fact, they are not. It’s important
to check occasionally to be sure the trail-
er bulbs are still working. You must also
check the lights every time you discon-
nect and then reconnect the wires.
Do not connect a trailer lighting system
directly to your vehicle’s lighting system.
Use only an approved trailer wiring har-
ness.
A HYUNDAI authorised repairer can
assist you in installing the wiring har-
ness.
Driving on grades
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 hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 70 km/h (45
mph) to reduce the possibility of engine
and transmission overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transmission,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimise heat build up
and extend the life of your transmission.WARNING
Failure to use an approved trailer
wiring harness could result in dam-
age to the vehicle electrical system
and/or personal injury.

Parking on hills
Generally, if you have a trailer attached to
your vehicle, you should not park your
vehicle on a hill. People can be seriously
or fatally injured, and both your vehicle
and the trailer can be damaged if unex-
pectedly roll down hill.
WARNING- Parking on a
hill
Parking your vehicle on a hill with a
trailer attached could cause seri-
ous injury or death, should the trail-
er break loose.
CAUTION
• 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 over-
heat.
If the needle of the coolant tem-
perature gauge moves across the
dial 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 pro-
ceed once the engine has cooled
sufficiently.
• You must decide driving speed
depending on trailer weight and
uphill grade to reduce the possi-
bility of engine and transmission
overheating.
CAUTION
Going uphill under hot ambient
temperature (above 35°C) with GVW
and/or trailer, a minimal fuel tank
level of 5 litre has to be assured in
order to prevent power limitation
due to fuel overheating as well as
further damages in the fuel injec-
tion equipment.

Maintenance when trailer towing
Your vehicle will need service more often
when you regularly pull a trailer.
Important items to pay particular atten-
tion to include engine oil, automatic
transmission fluid, axle lubricant and
cooling system fluid. Brake condition is
another important item to frequently
check. Each item is covered in this man-
ual, and the Index will help you find them
quickly. If you’re trailering, it’s a good idea
to review these sections before you start
your trip.
Don’t forget to also maintain your trailer
and towbar. Follow the maintenance
schedule 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.CAUTION
• Due to higher load during trailer
usage, overheating might occur
in hot days or during uphill driv-
ing. If the coolant gauge indicates
over-heating, switch off the A/C
and stop the vehicle in a safe area
to cool down the engine.
• When towing check transmission
fluid more frequently.
• If your vehicle is not equipped
with the air conditioner, you
should install a condenser fan to
improve engine performance
when towing a trailer.

Jump starting procedure
1. Make sure the booster battery is 12-
volt and that its negative terminal is
grounded.
2. If the booster battery is in another
vehicle, do not allow the vehicles to
touch.
3. Turn off all unnecessary electrical
loads.
4. Connect the jumper cables in the exact
sequence shown in the illustration.
First connect one end of a jumper
cable to the positive terminal of the
discharged battery (1), then connect
the other end to the positive terminal
on the booster battery (2).
Proceed to connect one end of the
other jumper cable to the negative ter-
minal of the booster battery (3), then
the other end to a solid, stationary,
metallic point (for example, the engine
lifting bracket) away from the battery
(4). Do not connect it to or near any
part that moves when the engine is
cranked.Do not allow the jumper cables to con-
tact anything except the correct battery
terminals or the correct ground. Do not
lean over the battery when making
connections.
5. Start the engine of the vehicle with the
booster battery and let it run at 2,000
rpm, then start the engine of the vehi-
cle with the discharged battery.
If the cause of your battery discharging is
not apparent, we recommend that the
system be checked by a HYUNDAI
authorised repairer.
Push-starting
Your manual transmission-equipped
vehicle should not be push-started
because it might damage the emission
control system.
Vehicles equipped with automatic trans-
mission cannot be push-started.
Follow the directions in this section for
jump-starting.
CAUTION- Battery cables
Do not connect the jumper cable
from the negative terminal of the
booster battery to the negative ter-
minal of the discharged battery.
This can cause the discharged bat-
tery to overheat and crack, releas-
ing battery acid.
WARNING
Never tow a vehicle to start it
because the sudden surge forward
when the engine starts could cause
a collision with the tow vehicle.

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the gear selector lever in P
(automatic transmission) or neutral
(manual transmission) and set the
parking brake. If the air conditioning is
on, turn it off.
3. If engine coolant is running out under
the car or steam is coming out from
the bonnet, stop the engine. Do not
open the bonnet until the coolant has
stopped running 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 operat-
ing. If the fan is not running, turn the
engine off.4. Check to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check
for coolant leaking from the radiator,
hoses or under the car. (If the air con-
ditioning had been in use, it is normal
for cold water to be draining from it
when you stop).
5. If the water pump drive belt is broken
or engine coolant is leaking out, stop
the engine immediately and we recom-
mend that you call a HYUNDAI autho-
rised repairer.6. If the cause of the overheating cannot
be found, wait until the engine temper-
ature has returned to normal. Then, if
coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
base of the radiator fill opening. Fill the
coolant expansion tank to the halfway
mark. To ensure the correct water to
coolant mix is obtained after top up,
testing by an authorised repairer is
required.
7. Proceed with caution until it is estab-
lished that the engine is operating nor-
mally. If overheating happens again,
we recommend that you call a
HYUNDAI authorised repairer.
CAUTION
• Serious loss of coolant indicates
there is a leak in the cooling sys-
tem and we recommend that the
system be checked by a HYUNDAI
authorised repairer.
• When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.
WARNING
Whilst the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot since steam
and boiling water may be ejected
from the radiator resulting in burns
or scalding.

Maintenance
ENGINE COOLANT
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 level at least once a year, at the
beginning of the winter season, and
before travelling to a colder climate.Checking the coolant level
CAUTION
• Do not drive with no engine
coolant. It may cause water pump
failure and engine seizure, etc.
• When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.WARNING
The electric motor (cool-
ing fan) is controlled by
engine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes 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 temperature decreases, the
electric motor will automatically
shut off. This is a normal condition.
WARNING
Removing radiator
cap
• Never attempt to remove the radi-
ator cap whilst the engine is
operating or hot. Doing so might
lead to cooling system and
engine damage and could result
in serious personal injury from
escaping 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. Step back whilst
the pressure is released from the
cooling system.
When you are sure all the pres-
sure has been released, press
down on the cap, using a thick
towel, and continue turning coun-
terclockwise to remove it.
(Continued)
(Continued)
• Even if the engine is not operat-
ing, do not remove the radiator
cap or the drain plug whilst the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.
