Driving tips38
5Maintenance 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 occurin hot days or during uphill driv-ing. If the coolant gauge indicates over-heating, switch off the A/Cand stop the vehicle in a safe areato cool down the engine.
 When towing check transmission fluid more frequently.
 If your vehicle is not equipped with the air conditioner, youshould install a condenser fan to improve engine performancewhen 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, havethe 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.

7ENGINE COOLING SYSTEMThe 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 untilit 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.
