*: if equipped
The SRSCM continually monitors all
SRS components while the ignition
switch is ON to determine if a crash
impact is severe enough to require air
bag deployment or pre-tensioner seat
belt deployment.
The SRS air bag warning light on the
instrument panel will illuminate for about
6 seconds after the ignition switch is
turned to the ON position, after which the
air bag warning light should go out.
If any of the following conditions occurs,
this indicates a malfunction of the SRS.
Have an authorized Kia dealer inspect
the air bag system as soon as possible.
The light does not turn on briefly when you turn the ignition ON.
The light stays on after illuminating for approximately 6 seconds.
The light comes on while the vehicle is in motion. The air bag modules are located both in
the center of the steering wheel and in
the front passenger's panel above the
glove box. When the SRSCM detects a
sufficiently severe impact to the front of
the vehicle, it will automatically deploy
the front air bags.
Upon deployment, tear seams molded
directly into the pad covers will separate
under pressure from the expansion of the
air bags. Further opening of the covers
then allows full inflation of the air bags.

Safety features of your vehicle
Why didn’t my air bag go off in a
collision? (Inflation and non-infla-
tion conditions of the air bag)
There are many types of accidents in
which the air bag would not be expect-
ed to provide additional protection.
These include rear impacts, second or
third collisions in multiple impact
accidents, as well as low speed
impacts. In other words, just because
your vehicle is damaged and even if it
is totally unusable, don’t be surprised
that the air bags did not inflate.

Driving your vehicle
Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
miles (kilometers) you can get from a gal-
lon (liter) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-ate rate. Don't make "jack-rabbit" starts
or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to the traffic so you don't have to
change speeds unnecessarily. Avoid
heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid unnec-
essary braking. This also reduces
brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your vehicle
uses. Driving at a moderate speed,
especially on the highway, is one of the
most effective ways to reduce fuel con-
sumption. Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.
Take care of your tires. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tire wear and may
also result in other problems as well as
greater fuel consumption. Keep your vehicle in good condition.
For better fuel economy and reduced
maintenance costs, maintain your vehi-
cle in accordance with the mainte-
nance schedule in section 7. If you
drive your vehicle in severe conditions,
more frequent maintenance is required
(see section 7 for details).
Keep your vehicle clean. For maximum service, your vehicle should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the vehicle. This
extra weight can result in increased
fuel consumption and also contribute
to corrosion.
Travel lightly. Don't carry unnecessary weight in your vehicle. Weight reduces
fuel economy.
Don't let the engine idle longer than necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.

Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
✽ ✽
NOTICE
Never exceed the maximum tire inflation
pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both the engine coolant and
engine oil.
Drive belt
A loose or damaged drive belt may over-
heat the engine.
WARNING
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
Always check the tires for proper
inflation before driving. For prop-
er tire pressures, refer to “Tires
and wheels” in section 8.
Driving on tires with no or insuffi- cient tread is dangerous. Worn-
out tires can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tires
should be replaced as soon as
possible and should never be
used for driving. Always check
the tire tread before driving your
vehicle. For further information
and tread limits, refer to “Tires
and wheels” in section 7.

What to do in an emergency
12
6
If you have a tire gauge, remove the
valve cap and check the air pressure.
If the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the cor-
rect pressure. If it is too high, adjust
it until it is correct. Always reinstall
the valve cap after checking or
adjusting the tire pressure. If the cap
is not replaced, air may leak from the
tire. If you lose a valve cap, buy
another and install it as soon as pos-
sible.
After you have changed wheels,
always secure the flat tire in its place
and return the jack and tools to their
proper storage locations. To prevent the jack, jack handle,
wheel lug nut wrench and spare tire
from rattling while the vehicle is in
motion, store them properly.CAUTION
Your vehicle has metric threads
on the wheel studs and nuts.Make certain during wheelremoval that the same nuts thatwere removed are reinstalled -or, if replaced, that nuts withmetric threads and the samechamfer configuration are used.Installation of a non-metricthread nut on a metric stud orvice-versa will not secure thewheel to the hub properly andwill damage the stud so that itmust be replaced.
Note that most lug nuts do nothave metric threads. Be sure touse extreme care in checkingfor thread style before installingaftermarket lug nuts or wheels.If in doubt, consult an author-ized Kia dealer.
WARNING- Wheel studs
If the studs are damaged, they
may lose their ability to retain
the wheel. This could lead to the
loss of the wheel and a collision
resulting in serious injuries.
WARNING - Inadequate
spare tire pressure
Check the inflation pressures as
soon as possible after installing
the spare tire. Adjust it to the
specified pressure, if necessary.
Refer to “Tires and wheels” in
section 8.
