Vehicle driving controls
Passing
You will need more passing distance ahead when towing a trailer. Likewise, due to the
increased vehicle length, you will need to go much farther beyond the passed vehicle
before you can return to your lane.
Reversing
Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left,
just move your hand to the left. To move the trailer to the right, move your hand to the
right. Always reverse slowly and have someone guide you, if possible.
Making turns
When turning with a trailer, make wider turns than normal. This is to make sure that your
trailer does not hit soft shoulders, curbs, road signs, trees, or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.
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 cluster will flash whenever you signal a turn
or lane change. If properly connected, the trailer lights will also flash to alert other drivers
to the fact that you are about to turn, change lanes, or stop.
When towing a trailer, the green arrows on your instrument cluster will flash for turns even
if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are see-
ing your signals when, in fact, they are not. It is important to check occasionally to make
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 harness.
Seek assistance from a professional workshop for the installation of the wiring harness.
Kia recommends visiting an authorized 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.
Driving on grades
Reduce speed before you start down a long or steep downgrade.
On a long uphill grade, shift down and reduce your speed to around 70 km/h (45 mph) to
reduce the possibility of motor overheating.
CAUTION
僅 To prevent motor overheating:
If you tow a trailer with the maximum gross vehicle weight and maximum trailer weight,
it can cause the motor to overheat. When driving in such conditions, stop the vehicle
until it cools down. You may proceed once the motor has cooled sufficiently.
When towing a trailer, your vehicle speed may be much slower than the general flow of
traffic, especially when climbing an uphill grade. Use the outer lane when towing a
trailer on an uphill grade. Choose your vehicle speed according to the maximum posted
speed limit for vehicles with trailers, the steepness of the grade, and your trailer weight.
僅 You must decide the driving speed depending on trailer weight and uphill grade to
reduce the possibility of motor overheating.
