NOTICE - NHTSA Safety
Corrosion Alert
NHTSA has warned all vehicle own-
ers of all brands that they must main-
tain their vehicles in a manner which
will prevent brake hose and brake line
failures due to corrosion when such
vehicles are exposed to winter road
salt and related chemicals. While seri-
ous corrosion conditions typically only
manifest themselves as safety issues
after 7 years of vehicle use, the corro-
sion process starts immediately and
thus underbody cleaning maintenance
must commence from your vehicle's
first exposure to road salts and chem-
icals. NHTSA urges vehicle owners to
take the following steps to prevent
corrosion:
(Continued)(Continued)
1. Wash the undercarriage of your
vehicle regularly throughout the
winter and do a thorough washing
in the spring to remove road salt
and other de-icing chemicals.
2. Monitor the brake system for signs of corrosion by having regu-
lar professional inspections and
watching for signs of problems,
including loss of brake fluid,
unusual leaks and soft or spongy
feel in the brake pedal.
3. Replace the entire brake pipe assembly if you find severe corro-
sion that causes scaling or flaking
of brake components.
Brake/Clutch fluid
Check the brake/clutch fluid level in
the brake/clutch fluid reservoir. The
level should be between the “MIN”
and “MAX” marks on the side of the
reservoir. Use only hydraulic
brake/clutch fluid conforming to DOT
4 specification.
Parking brake
Inspect the parking brake system
including the parking brake lever and
cables.

Maintenance
Brake discs, pads, calipers
and rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and damage.

CHECKING FLUID LEVELS
When checking engine oil, engine
coolant, brake fluid, and washer fluid,
always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant or fluid. This is espe-
cially important in dusty or sandy
areas and when the vehicle is used
on unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine and
other mechanisms that could be
damaged.

BRAKE/CLUTCH FLUID (IF EQUIPPED)
Checking the brake/clutch
fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between the MAX (Maximum) and
MIN (Minimum) marks on the side of
the reservoir.
Before removing the reservoir cap
and adding brake/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch
fluid contamination.If the level is low, add fluid until you
reach the MAX (Maximum) level. The
level will fall with accumulated
mileage. This is a normal condition
associated with the wear of brake lin-
ings. If the fluid level is excessively
low, have the brake system checked
by an authorized Kia dealer.
Use only the specified brake/clutch
fluid. (Refer to “Recommended lubri-cants and capacities” in chapter 8.)
Never mix different types of fluid.
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized Kia dealer.
When changing and adding
brake/clutch fluid, handle it carefully.
Do not let it come in contact with
your eyes. If brake/clutch fluid should
come in contact with your eyes,
immediately flush them with a large
quantity of fresh tap water. Have your
eyes examined by a doctor as soon
as possible.
Brake/clutch fluid which has been
exposed to open air for an extended
time should never be used as its
quality cannot be guaranteed. It
should be disposed of properly.
OYB076013CAUTION - Brake/clutch fluid
Do not allow brake/clutch fluid tocontact the vehicle's body paint,as paint damage will result.
CAUTION - Proper fluid
Only use brake/clutch fluid inbrake system. Small amounts ofimproper fluids (such as engineoil) can cause damage to thebrake system.

Checking the parking brake
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard while fully applying it
from the released position. Also, the
parking brake alone should securely
hold the vehicle on a fairly steep
grade. If the stroke is more or less
than specified, have the parking
brake adjusted by an authorized Kia
dealer.
Stroke : 5~7 “clicks’’ at a force of 44
lbs (20 kg, 196 N).

Maintenance
Disc brake pads should be inspectedfor wear whenever tires are rotated.
Rotate radial tires that have an
asymmetric tread pattern only from
front to rear and not from right to left.
Wheel alignment and tire bal-
ance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
WARNING - Mixing tires
Do not use the compact spare tire (if equipped) for tire rota-
tion.
Do not mix bias ply and radial ply tires under any circum-
stances. This may cause
unusual handling characteris-
tics.
CAUTION - Wheel weight
Improper wheel weights candamage your vehicle's alu-minum wheels. Use onlyapproved wheel weights.

Tire replacement
If the tire is worn evenly, a tread wear
Indicator (A) will appear as a solid
band across the tread. This shows
there is less than 1/16 inch (1.6 mm)
of tread left on the tire. Replace the
tire when this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire. The ABS works by comparing the
speed of the wheels. The tire size
affects wheel speed. When replacing
tires, all 4 tires must use the same
size originally supplied with the vehi-
cle. Using tires of a different size can
cause the ABS (Anti-lock Brake
System) and ESC (Electronic
Stability Control) to work irregularly.
✽ ✽
NOTICE
• We recommend that when replac-
ing tires, use the same which were
originally supplied with the vehi-
cle. If not, driving performance
could be altered.
• It is best to replace all four tires at the same time. If that is not possi-
ble, or necessary, then replace the
two front or two rear tires as a pair.
Replacing just one tire can serious-
ly affect your vehicle's handling.
Compact spare tire replacement
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire.
