Driving your vehicle
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
trailer bulbs are still working. You must
also check the lights every time you dis-
connect 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.
Have yourself assisted by a professional
workshop in installing the wiring har-
ness.
Kia recommends to visit an authorised
Kia dealer/service partner.
WARNING
Failure to use an approved trailer wiring
harness could result in damage to the
vehicle electrical system and/or personal
injury.
Detection of trailer light connec-
tion
This functionality is only given with gen-
uine accessories (tow bar and wiring
harness) that recognise when a trailer is
connected and consequently inform the
vehicle systems. Trailer recognition
works as follows: when a trailer socket is
plugged in, either the brake pedal shall
be pushed or turn signal lamps activated
; the electronic control unit will then
detect the trailer because of the power
consumption by the trailer lighting and
inform the vehicle systems. When the
trailer is disconnected, the brake pedal
shall be pushed again or turn signal
lamps activated for the control unit to be
5 92
able to detect that there is no power
consumption anymore by trailer lighting;
the assistance systems that were turned
off will automatically turn on again.
It is the driver's responsibility to ensure
that all electrical connections are work-
ing and all trailer lights are operating
before and during towing. You must per-
form manual checks.
CAUTION
僅 Use only genuine electrical connec-
tions. Do not attempt to arbitrarily
splice or directly connect the trailer
wiring using any other methods.
Doing so may damage the vehicle's
electrical system, resulting in malfunc-
tions.
僅 If your vehicle has equipped trailer
package, the various functions of the
driver assistance system are automat-
ically switched off when a trailer or
other tow bar mounted carriers are
connected. The reasons to turn off the
functions automatically are
1. because a trailer may interfere with
the correct functionality of the sys-
tem,
2. because the trailer may otherwise
cause unforeseen behavioral insta-
bility or
3. because of legislation.
This functionality is only given with
genuine accessories that recognise
when a trailer is connected and con-
sequently inform the vehicle systems.
If functions are turned off, you cannot
get help from the particular system;
always drive with care! Also read the
related sections of the driver assis-
tance system.
