Driving your vehicle
WARNING
Do not connect a trailer lighting
system directly to your vehi-
cle's lighting system. Use an
approved trailer wiring harness.
Failure to do so could result in
damage to the vehicle electrical
system and/or personal injury.
Consult a HYUNDAI authorised
repairer for assistance.
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 (45 mph) to reduce the possi-
bility of engine and transmission
overheating.

If your trailer weighs more than the
maximum trailer weight without trail-
er brakes and you have automatic
transmission, 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.
NOTICE
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
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.
• When towing a trailer, your vehi-
cle speed may be much slower
than the general flow of traffic,
especially when climbing an
uphill gradient. Use the right
hand lane when towing a trailer
on an uphill gradient. Choose
your vehicle speed according to
the maximum posted speed limit
for vehicles with trailers, the
steepness of the gradient, and
gauge
your trailer weight.
• Vehicles equipped with a auto-
matic transmission when towing
a trailer on steep gradients,
need to be aware that the clutch
in the transmission could over-
heat.
