Specifications, Consumer information, Reporting safety defects
Roadside Assistance is provided on all new current
model year Kia Vehicles from the date the vehicle is deliv-
ered to the first retail buyer or otherwise put into use (in-
service date), whichever is earlier, for a period of 60
months or 60,000 miles, whichever is earlier, subject to
the terms, conditions and exclusions set forth in the Kia
Warranty and Consumer Information Manual applicable
to your model year vehicle.
KMA reserves the right to limit or deny services or other
benefits to any owner or driver when, in KMA's judgment,
the claims and/or service requests are excessive in fre-
quency or type of occurrence.
Toll free consumer assistance
Kia's toll-free Consumer Assistance hot line is staffed
from 5:00 AM to 6:00 PM PST, Monday through Friday
and is accessible by dialing 1-800-333-4Kia (4542).
For more information regarding assistance available,
please refer to your Kia Warranty & Consumer
Information Manual.
Emergency roadside assistance
Kia's toll free Roadside Assistance hot line is staffed 24
hours a day, 365 days a year and is accessible by dialing
1-800-333-4Kia (4542).
Please note that you must provide your Vehicle
Identification Number (VIN) to verify coverage at the time
of your call. The VIN can be found on the dash of your
vehicle on the driver’s side, on the door jamb of the dri-
ver’s door, your vehicle’s registration or proof of insur-
ance card.
Kia utilizes a network of over 30,000 roadside assistance
providers. Should you accidentally run out of fuel, require
a battery jump, or need help changing a tire, a Kia
Roadside Assistance Representative will dispatch some-
one to deliver a small quantity of gas, change a flat tire
with your inflated spare, or arrange a battery jump to
allow you to proceed to your destination. We have access
to a network of over 10,000 locksmiths to help you should
you become locked out of your Kia.
In the event that mechanical difficulty renders your vehi-
cle undriveable due to a warranty-related concern, Kia’s
Roadside Assistance Representative will arrange to
transport your vehicle to the nearest Kia dealer or to an
authorized Kia alternative service location.

Registering your vehicle in a foreign country
If you plan to register your vehicle in a foreign country,
you should confirm that it conforms to the regulations in
that country. Even if you successfully register the vehicle
in a foreign country, you may experience the following
problems and should therefore consider the possibility of
having to deal with them:
1. The fuel specified for your vehicle may be unavailable.If other than the specified fuel is used, it could cause
damage to the engine, the fuel injection system, and
other fuel-related parts which may not be covered
under your New Vehicle Emissions Limited Warranty.
2. We must, therefore, clearly state that when you leave the country in which you purchased your Kia new and
register it in another country, problems arising from the
use of fuel other than the specified fuel are not subject
to manufacturer’s warranty. Because vehicles like
yours may not be marketed in the new country of reg-
istration, parts, servicing techniques and tools neces-
sary to maintain and repair your vehicle may be
unavailable.
Even if vehicles like yours are sold there, mechanical
specifications required by the government may vary
enough from the country of purchase to cause addi-
tional problems. 3. There may not be an Authorized Kia Dealer in the area
in which you plan to register your vehicle. You may
additionally experience difficulty in obtaining services
in a foreign country for any number of reasons.
Further, we cannot assume any responsibility for prob-
lems that result from unsatisfactory service or lack of
service outside of the United States.
