Driving tips

After off-road driving
Remove any brush or debris that has col-
lected on the underbody, chassis or
under the hood. These accumulations
can be a fire hazard.
After driving in mud or sand, clean and
check the brake linings. Accumulation of
mud or sand can cause glazing and
uneven braking. Check the body struc-
ture, steering, suspension, wheels, tires,
and exhaust system for damage. Also,
check the fuel lines and cooling system
for any leakage. Your vehicle will also
require more frequent service due to off-
road use.WARNING- Water
Driving through rushing water can
be dangerous. Deep water can
sweep your vehicle downstream
and you and your passengers could
drown. If it’s only inches deep, it
can still wash away the ground from
under your tires, and you could lose
traction and roll the vehicle. Never
drive through rushing water.

Maintenance when trailer towing
Your vehicle will need service more often
when you regularly pull a trailer.
Important items to pay particular atten-
tion to include engine oil, automatic
transmission fluid, axle lubricant and
cooling system fluid. Brake condition is
another important item to frequently
check. Each item is covered in this man-
ual, and the Index will help you find them
quickly. If you’re trailering, it’s a good idea
to review these sections before you start
your trip.
Don’t forget to also maintain your trailer
and hitch. Follow the maintenance
schedule that accompanied your trailer
and check it periodically. Preferably, con-
duct the check at the start of each day’s
driving. Most importantly, all hitch nuts
and bolts should be tight.CAUTION
• Due to higher load during trailer
usage, overheating might occur
in hot days or during uphill driv-
ing. If the coolant gauge indicates
over-heating, switch off the A/C
and stop the vehicle in a safe area
to cool down the engine.
• When towing check transmission
fluid more frequently.
• If your vehicle is not equipped
with the air conditioner, you
should install a condenser fan to
improve engine performance
when towing a trailer.

In case of an emergency
OVERHEATING
If your temperature gauge indicates over-
heating, if you experience a loss of
power, or if you hear a loud knocking or
pinging noise, the engine has probably
overheated. Should any of these symp-
toms occur, use the following procedure:
1. Turn on the hazard warning flasher,
then drive to the nearest safe location
and stop your vehicle; set the automat-
ic transmission in P (Park), or shift the
manual transmission to N (Neutral)
and apply the parking brake.
2. Make sure the air conditioner is off.
3. If coolant or steam is boiling out of the
radiator, stop the engine and call an
Authorized Kia Dealer for assistance.If coolant is not boiling out, allow the
engine to idle and open the hood to
permit the engine to cool gradually.
If the temperature does not go down
with the engine idling, stop the engine
and allow sufficient time for it to cool.
4. The coolant level should then be
checked. If the level in the reservoir is
low, look for leaks at the radiator hoses
and connections, heater hoses and
connections, radiator, and water
pump. If you find a major leak or anoth-
er problem that may have caused the
engine to overheat, do not operate the
engine until it has been corrected. Call
an Authorized Kia Dealer for assis-
tance. If you do not find a leak or other
problem, carefully add coolant to the
reservoir.
If the engine frequently overheats, have
the cooling system checked and repaired
by an Authorized Kia Dealer.
WARNING- Removing
radiator cap
Do not remove the radiator cap
when the engine and radiator are
hot. Scalding hot coolant and steam
may blow out under pressure. This
could cause serious injury.

ENGINE COOLING SYSTEM
The high-pressure cooling system has a
reservoir filled with a mixture of
antifreeze and water. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.
Checking the coolant level
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine is
cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an Authorized
Kia Dealer for a cooling system inspec-
tion.WARNING- Removing
radiator cap
• Never attempt to remove the radi-
ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.
(Continued)
(Continued)
• Turn the engine off and wait until
it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
• Even if the engine is not operat-
ing, do not remove the radiator
cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.
