Driving your vehicle
Even with the anti-lock brake sys-tem, your vehicle still requires suf-
ficient stopping distance. Always
maintain a safe distance from the
vehicle in front of you.
Always slow down when cornering. The anti-lock brake system cannot
prevent accidents resulting from
excessive speeds.
On loose or uneven road surfaces, operation of the anti-lock brake
system may result in a longer stop-
ping distance than for vehicles
equipped with a conventional
brake system. The ABS warning light will stay on for
approximately 3 seconds after the
engine start/stop button is ON.
During that time, the ABS will go
through self-diagnosis and the light
will go off if everything is normal. If
the light stays on, you may have a
problem with your ABS. Contact an
authorized Kia dealer as soon as
possible. When you drive on a road having
poor traction, such as an icy road,
and have operated your brakes
continuously, the ABS will be active
continuously and the ABS warning
light may illuminate. Pull your vehi-
cle over to a safe place and stop
the engine.
Restart the engine. If the ABS warning light goes off, then your
ABS system is normal. Otherwise,
you may have a problem with the
ABS. Contact an authorized Kia
dealer as soon as possible.
✽ ✽ NOTICE
When you jump start your vehicle
because of a drained battery, the
engine may not run as smoothly and
the ABS warning light may turn on at
the same time. This happens because
of low battery voltage. It does not
mean your ABS has malfunctioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.

Driving your vehicle
The use of chains may adverselyaffect vehicle handling.
Do not exceed 20 mph (30 km/h) or the chain manufacturer’s recom-
mended speed limit, whichever is
lower.
Drive carefully and avoid bumps, holes, sharp turns, and other road
hazards, which may cause the
vehicle to bounce.
Avoid sharp turns or locked-wheel braking.Use high quality ethylene gly-
col coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 8. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 8. The level of charge in
your battery can be checked by an
authorized Kia dealer or a service
station.
Change to "winter weight" oil
if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 9 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
Kia dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 8 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.CAUTION- Snow chains
Chains that are the wrong size or improperly installed candamage your vehicle's brakelines, suspension, body andwheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1. If your vehicle has an automatictransaxle, be sure the shift lever is
in N (Neutral) or P (Park) and the
emergency brake is set.
2. Check the battery connections to be sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you oper-
ate the starter, the battery is dis-
charged.
4. Check the starter connections to be sure they are securely tight-
ened.
5. Do not push or pull the vehicle to start it. See instructions for "Jump
starting".
If engine turns over normally
but does not start
1. Check the fuel level.
2. With the ignition switch in theLOCK position, check all connec-
tors at the ignition coils and spark
plugs. Reconnect any that may be
disconnected or loose.
3. Check the fuel line in the engine compartment.
4. If the engine still does not start, call an authorized Kia dealer or
seek other qualified assistance.
WARNING - Push/
pull start
Do not push or pull the vehicle
to start it. Push or pull starting
may cause the catalytic con-
verter to overload and create a
fire hazard.

Jump starting
Jump starting can be dangerous if
done incorrectly. Therefore, to avoid
harm to yourself or damage to your
vehicle or battery, follow these jump
starting procedures. If in doubt, we
strongly recommend that you have a
competent technician or towing serv-
ice jump start your vehicle.
CAUTION - Push/pull start
to 12 Volt Battery
Use only a 12-volt jumper sys- tem. You can damage a 12-voltstarting motor, ignition system,and other electrical partsbeyond repair by use of a 24-volt power supply (either two12-volt batteries in series or a24-volt motor generator set).
WARNING- Battery
Never attempt to check the elec-
trolyte level of the battery as
this may cause the battery to
rupture or explode.
WARNING- Frozen batteries
Do not attempt to jump start the
vehicle if the discharged battery
is frozen or if the electrolyte
level is low as the battery may
rupture or explode.
WARNING- Sulfuric acid risk
When jump starting your vehi-
cle, be careful not to get acid on
yourself, your clothing or on the
vehicle. Automobile batteries
contain sulfuric acid. This is poi-
sonous and highly corrosive.
WARNING- Battery
Keep all flames or sparks away
from the battery. The battery
produces hydrogen gas which
will explode if exposed to flame
or sparks.OJFH065046L

Jump starting procedure
1.Make sure the booster battery is12-volt and that its negative termi-
nal is grounded.
2.If the booster battery is in another vehicle, do not allow the vehicles to
come in contact.
3.Turn off all unnecessary electrical loads.
4.Connect the jumper cables in the exact sequence shown in the illus-
tration. First connect one end of a
jumper cable to the positive termi-
nal of the discharged battery (1),
then connect the other end to the
positive terminal of the booster
battery (2).
Proceed to connect one end of the
other jumper cable to the negative
terminal of the booster battery (3),
then the other end to a solid, sta-
tionary, metallic point (for example,
the engine lifting bracket) away
from the battery (4). Do not con-
nect it to or near any part that
moves when the engine is cranked. Do not allow the jumper cables to
contact anything except the correct
battery terminals or the correct
ground. Do not lean over the bat-
tery when making connections.
5.Start the engine of the vehicle with the booster battery and let it run at
2,000 rpm, then start the engine of
the vehicle with the discharged
battery.
If the cause of your battery discharg-ing is not apparent, you should haveyour vehicle checked by an author-ized Kia dealer.
Push-starting
Vehicles equipped with automatic
transaxle lock system cannot be
push-started.
Follow the directions in this section
for jump-starting.
WARNING - Tow starting
vehicle
Never tow a vehicle to start it.
When the engine starts, the
vehicle can suddenly surge for-
ward and could cause a colli-
sion with the tow vehicle.
WARNING - Battery cables
Do not connect the jumper cable
from the negative terminal of the
booster battery to the negative
terminal of the discharged bat-
tery. This can cause the dis-
charged battery to overheat and
crack, releasing battery acid.
Make sure to connect one end of
the jumper cable to the negative
terminal of the booster battery,
and the other end to a metallic
point, far away from the battery.
