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 occasion-
ally to be sure the trailer bulbs are still
working. You must also check the
lights every time you disconnect and
then reconnect the wires.
Do not connect a trailer lighting sys-
tem directly to your vehicle's lighting
system. Use only an approved trailer
wiring harness.
For installing the wiring harness, we
recommend that you contact to an
authorised Kia dealer.
WARNING
Failure to use an approved trail-
er wiring harness could result
in damage to the vehicle electri-
cal system and/or personal
injury.
Driving your vehicle
Driving on grades
Reduce the 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 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 transaxle over-
heating.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes and you have an automat-
ic transaxle, 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 transaxle.
