Maintenance
Underbody maintenance
Road salt and other corrosive chemi-
cals are used in cold weather states to
melt snow and prevent ice accumula-
tion. If these chemicals are not regu-
larly removed, they will corrode the
vehicle underbody and over time dam-
age fuel lines, the fuel tank retention
system, the vehicle suspension, the
exhaust system, and even the body
frame. The National Highway Traffic
Safety Administration has warned all
vehicle owners of all brands of the
need to take the following steps:
Wash the undercarriage of yourvehicle regularly during the winter
and whenever your vehicle has
been exposed to such salts or
chemicals.
Do a thorough washing of the undercarriage at the end of the
winter.
Use professional service techni- cians or governmental inspection
stations to annually inspect for cor-
rosion. Immediately seek an inspection of
your vehicle if you become visually
aware of corrosion flaking or scal-
ing or if you become aware of a
change in vehicle performance,
such as soft or spongey brakes,
fluids leaking, impairment of direc-
tional control, suspension noises
or rattling metal straps.
Aluminum wheel maintenance
The aluminum wheels are coated
with a clear protective finish.
Do not use any abrasive cleaner,polishing compound, solvent, or
wire brushes on aluminum wheels.
They may scratch the finish.
Clean the wheel when it has cooled.
Use only a mild soap or neutral detergent, and rinse thoroughly with
water. Also, be sure to clean the
wheels after driving on salted roads.
This helps prevent corrosion.
Avoid washing the wheels with highspeed vehicle wash brushes.
Do not use any alkaline or acid detergents It may damage and cor-
rode the aluminum wheels coated
with a clear protective finish.

the terms, conditions and exclusions set forth in the Kia
Warranty and Consumer Information Manual applicable

Please note that you must provide your Vehicle

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.
