Driving your vehicle
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 transaxle fluid, axle lubricant
and cooling system fluid. Brake con-
dition is another important item to
frequently check. If you’re trailering,
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.
• When towing check automatic transaxle fluid more frequently.
• 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
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 transaxle/dual clutch
transmission vehicle) or neutral (for
manual transaxle/dual clutch trans-
mission vehicle) and set the park-
ing brake. If the air conditioning 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 theradiator, 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 a HYUNDAI
authorised repairer for assistance.
IF THE ENGINE OVERHEATS
Whilst the engine isrunning, keep hands,
clothing and tools
away from the mov-
ing parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.

6. If you cannot find the cause of theoverheating, 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 a
HYUNDAI authorised repairer for
assistance.
•Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked by a
HYUNDAI authorised repairer.
•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.
CAUTION
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
counterclockwise slowly to the
first stop. Step back whilst the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.
