Driving your vehicle
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 45 mph (70km/h) to reduce the possibility of engine
and transaxle overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transaxle,
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 transaxle.CAUTION
 When towing a trailer on steepgrades (in excess of 6%) pay
close attention to the engine coolant temperature gauge toensure the engine does not over-heat.
If the needle of the coolant tem-perature gauge moves across thedial 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 anduphill grade to reduce the possi-bility of engine and transaxle
overheating.WARNING
Failure to use an approved trailer wiring harness could result in dam-
age to the vehicle electrical system
and/or personal injury.

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 shift lever in P (automatic transaxle) or neutral (manual
transaxle) and set the parking brake. If
the air conditioning is on, turn it off.
3. If engine coolant is running out under the vehicle or steam is coming out
from the bonnet, stop the engine. Donot 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 vehicle. (If the air
conditioning had been in use, it is nor-
mal 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, ifcoolant 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 a HYUNDAI authorisedrepairer is required.
7. Proceed with caution, keeping alert for further signs of overheating. If over-
heating happens again, we recom-
mend that you call a HYUNDAI autho-
rised repairer.
CAUTION
Serious loss of coolant indicates
there is a leak in the cooling systemand we recommend that the system
be checked by a HYUNDAI autho-rised repairer.
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. This can
allow coolant to be blown out of the
opening and cause serious burns.

Maintenance
Check the condition and connections of all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks on
the side of the coolant reservoir when theengine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F (MAX), but do not overfill. If fre-
quent coolant refill is required, we rec-
ommend that the system be inspected by
a HYUNDAI authorised repairer.

(Continued)Step back whilst the pressure isreleased from the cooling sys-
tem. When you are sure all thepressure has been released,
press down on the cap, using a
thick towel, and continue turning
counterclockwise to remove it.
 Even if the engine is not operat- ing, do not remove the radiatorcap 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.WARNING
The electric motor (cool-
ing fan) is controlled byengine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes operate evenwhen 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.
If your vehicle is equipped with
GDI, the electric motor (cooling fan)
may operate until you disconnect
the nagative battery cable.

Recommended engine coolant
 When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
 The engine in your vehicle has alumi
-num engine parts and must be protect-
ed by an ethylene-glycol-based coolant
to prevent corrosion and freezing.
 DO NOT USE alco hol or methanol
coolant or mix them with the specifiedcoolant.
 Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution. For mixture percentage, refer to the fol-
lowing table.
WARNING
Radiator cap
Do not remove the radiator cap when the engine and radiator are
hot. Scalding hot coolant and
steam may blow out under pres-
sure causing serious injury.
