engine KIA Sephia 2007 2.G Workshop Manual

Driving tips25FUEL REQUIREMENTSGasoline engine (unleaded)Your new Kia vehicle is designed to
use only unleaded fuel with a mini-
mum Octane Rating of 87 Anti-
Knock Index (AKI).✽ ✽NOTICENEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and will
damage the engine control system’s
oxygen sensor and affect emission
control.
Never add any fuel system cleaning
agents to the fuel tank other than
what Kia has specified. (Consult an
Authorized Kia Dealer for details.)
Gasoline containing alcohol
and methanolGasohol, a mixture of gasoline and
ethanol (also known as grain alco-
hol), and gasoline or gasohol con-
taining methanol (also known as
wood alcohol) are being marketed
along with or instead of leaded or
unleaded gasoline.
Do not use gasohol containing more
than 10% ethanol, and do not use
gasoline or gasohol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system.
Discontinue using gasohol of any
kind if drivability problems occur. Vehicle damage or driveability prob-
lems may not be covered by the
manufacturer’s warranty if they result
from the use of:
1. Gasohol containing more than
10% ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.

EMISSION CONTROL SYSTEMThe emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the
Warranty & Consumer Information
Manual in your vehicle.Vehicle modifications This vehicle should not be modified.
Modification of your Kia could affect
its performance, safety or durability,
may violate governmental safety and
emissions regulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
Engine exhaust gas precau-
tions (carbon monoxide)  Carbon monoxide can be presentwith other exhaust fumes.
Therefore, if you smell exhaust
fumes of any kind inside your vehi-
cle, have it inspected and repaired
immediately by an authorized Kia
dealer. If you ever suspect exhaust
fumes are coming into your vehi-
cle, drive it only with all the win-
dows fully open. Have your vehicle
checked and repaired immediately.  Do not operate the engine in con-
fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in or
out of the area.
 When the vehicle is stopped in an open area for more than a short
time with the engine running,
adjust the ventilation system (as
needed) to draw outside air into the
vehicle.
 Never sit in a parked or stopped vehicle for any extended time with
the engine running.
 When the engine stalls or fails to start, excessive attempts to re-
start the engine may cause dam-
age to the emission control sys-
tem.

WARNING
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
following to avoid CO impair-
ment.

Driving tips45Operating precautions for cat-
alytic converters Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
 Use only UNLEADED FUEL forgasoline engine (unleaded).
 Do not operate the vehicle when there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
 Do not misuse or abuse the engine. Examples of misuse are
coasting with the ignition off and
descending steep grades in gear
with the ignition off.  Do not operate the engine at high
idle speed for extended periods (5
minutes or more).
 Do not modify or tamper with any part of the engine or emission con-
trol system. All inspections and
adjustments must be made by an
authorized Kia dealer.
Failure to observe these precautions
could result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.

Driving tips
BEFORE DRIVING Before entering vehicle: Be sure that all windows, outsidemirror(s), and outside lights are
clean.
 Check the condition of the tires.
 Check under the vehicle for any sign of leaks.
 Be sure there are no obstacles behind you if you intend to back up.Necessary inspections Fluid levels, such as engine oil,
engine coolant, brake fluid, and
washer fluid should be checked on a
regular basis, with the exact interval
depending on the fluid. Further
details are provided in Section 7,
Maintenance.
Before starting  Close and lock all doors.
 Position the seat so that all con-trols are easily reached.

WARNING
- Driving under
the influence of alcohol or
drugs
Drinking and driving is danger-
ous. Drunk driving is the num-
ber one contributor to the high-
way death toll each year. Even a
small amount of alcohol will
affect your reflexes, perceptions
and judgement.
You are much more likely to
have a serious accident if you
drink and drive.
If you are drinking or taking
drugs, don’t drive. Do not ride
with a driver who has been
drinking or taking drugs.
Choose a designated driver or
call a cab.
Driving while under the influ-
ence of drugs is as dangerous
or more dangerous than driving
drunk.

Driving tips65SUGGESTIONS FOR ECONOMICAL OPERATIONYour 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 kilometers (miles) you can get
from a liter (gallon) of fuel. To operate
your vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
 Avoid lengthy warm-up idling.Once the engine is running
smoothly, begin driving.
Remember, engine warm-up may
take a little longer on cold days.
 Save fuel by accelerating slowly after stopping.
 Keep the engine in tune and follow the recommended periodic mainte-
nance schedule. This will increase
the life of all parts and lower your
operating costs.  Do not use the air conditioner
unnecessarily.
 Slow down when driving on rough roads.
 For longer tire life and better fuel economy, always keep the tires
inflated to the recommended pres-
sures.
 Maintain a safe distance from other vehicles to avoid sudden stops.
This will reduce wear on brake lin-
ings and pads. Driving in such a
way will also save fuel because
extra fuel is required to accelerate
back to driving speed.
 Do not carry unnecessary weight in the vehicle.
 Do not rest your foot on the brake pedal while driving. This can cause
needless wear, possible damage
to the brakes, and poor fuel econo-
my.
 Improper wheel alignment results in faster tire wear and lower fuel
economy.  Open windows at high speeds can
reduce fuel economy.
 Fuel economy is less in crosswinds and headwinds. To help offset
some of this loss, slow down when
driving in these conditions.
Keeping a vehicle in good operating
condition is important both for econ-
omy and safety. Therefore, have an
authorized Kia dealer perform
scheduled inspections and mainte-
nance.

WARNING
- Engine off
during motion
Never turn the engine off to
coast down hills or anytime the
vehicle is in motion. The power
steering and power brakes will
not function properly without
the engine running. Instead,
downshift to an appropriate
gear for engine braking effect.

Driving tips
SPECIAL DRIVING CONDITIONS Hazardous driving conditions When hazardous driving conditions
are encountered such as water,
snow, ice, mud, sand, or similar haz-
ards, follow these suggestions:
 Drive cautiously and allow extradistance for braking.
 Avoid sudden movements in brak- ing or steering.
 When braking, pump the brake pedal with a light up-and-down
motion until the vehicle is stopped.  If stalled in snow, mud, or sand,
use second gear. Accelerate slow-
ly to avoid spinning the drive
wheels.
 Use sand, rock salt, tire chains, or other non-slip material under the
drive wheels to provide traction
when stalled in ice, snow, or mud.
Rocking the vehicle If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between 1 (First) and R
(Reverse) in vehicles equipped with
a manual transaxle or R (Reverse)
and any forward gear in vehicles
equipped with an automatic
transaxle. Do not race the engine,
and spin the wheels as little as pos-
sible. If you are still stuck after a few
tries, have the vehicle pulled out by a
tow vehicle to avoid engine overheat-
ing and possible damage to the
transaxle.

WARNING
- Downshifting
Downshifting with an automatic
transaxle, while driving on slip-
pery surfaces can cause an
accident. The sudden change in
tire speed could cause the tires
to skid. Be careful when down-
shifting on slippery surfaces.
CAUTION
Prolonged rocking may cause engine over-heating, transaxledamage or failure, and tire dam-age.
WARNING
Do not pump the brake pedal on
a vehicle equipped with ABS.

Driving tips
 Driving too fast through large pud-dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly.
 If you believe you may have gotten your brakes wet, apply them lightly
while driving until normal braking
operation returns.
Winter driving We recommend that you carryemergency equipment, including a
window scraper, windshield de-
icer, a bag of sand or salt, flares, a
small shovel and jumper cables.
 Make sure you have sufficient eth- ylene-glycol coolant in the radiator.
 Check the battery condition and cables. Cold temperatures reduce
the capacity of any battery, so it
must be in excellent condition to
provide enough winter starting
power.
 Make sure the engine oil viscosity is suitable for cold weather.
 Check the ignition system for loose connections and damage.  Use antifreeze-formulated wind-
shield washer fluid. (Do not use
engine coolant antifreeze.)
 Do not use the parking brake if it might freeze. When parking, shift
to 1 (First) or R (Reverse) with a
manual transaxle or P (Park) with
an automatic transaxle and block
the rear wheels.

This section contains many time-
tested, important trailering tips and
safety rules. Many of these are
important for your safety and that of
your passengers. Please read this
section carefully before you pull a
trailer.
Load-pulling components such as
the engine, transaxle, wheel assem-
blies, and tires are forced to work
harder against the load of the added
weight. The engine is required to
operate at relatively higher speeds
and under greater loads. This addi-
tional burden generates extra heat
which creates more wear in engine,
and a shortened engine life. The trail-
er also adds considerably to wind
resistance, increasing the pulling
requirements.
If you do decide to pull a trailerHere are some important points if
you decide to pull a trailer:
 Consider using a sway control. You
can ask a hitch dealer about sway
control.
 After your odometer indicates 800 km (500 miles) or more, you can
tow a trailer. For the first 800 km
(500 miles) that you tow a trailer,
don’t drive over 80 km/h (50 mph)
and don’t make starts at full throt-
tle. This helps your engine and
other parts of your vehicle “wear” in
at the heavier loads.
 Always drive your vehicle at a mod- erate speed (less than 100 km/h
(60 mph)).
 The important considerations have to do with weight: Weight of the trailer
How heavy can a trailer safely be? It
should never weigh more than the
maximum trailer weight with trailer
brakes. But even that can be too
heavy.
If you feel that the trailer is adversely
affecting the movement of your vehi-
cle, reduce your speed, avoid
uneven or winding roads, avoid
roads with steep grades, and/or light-
en your trailer load.

Do not connect a trailer lighting sys-
tem directly to your vehicle’s lighting
system. Use only an approved trailer
wiring harness.
Your Authorized Kia Dealer can
assist you in installing the wiring har-
ness.
Driving on grades Reduce speed and shift to a lower
gear before you start down a long or
steep downgrade. If you don’t shift
down, you might have to use your
brakes so much that they would get
hot and no longer operate efficiently.
On a long uphill grade, shift down
and reduce your speed to around 70
km/h (45 mph) to reduce the possi-
bility of engine and transaxle over-
heating.
Operating your vehicle in D (Drive)
when towing a trailer will minimize
heat buildup and extend the life of
your transaxle.
WARNING
- Trailer wiring
harness
Failure to use an approved trail-
er wiring harness could result in
damage to the vehicle's electri-
cal system, there by disabling
the brake light system resulting
in an accident.
CAUTION
When towing a trailer on steep grades especially (in excess of6%) pay close attention to theengine coolant temperaturegauge to ensure the enginedoes not overheat. If the needleof the coolant temperaturegauge moves across the dialtowards “H” (HOT), pull over andstop as soon as it is safe to doso, and allow the engine to idleuntil it cools down. You may pro-ceed once the engine hascooled sufficiently.

Parking on hills Generally, you should not park your
vehicle, with a trailer attached, on a
hill. People can be seriously or fatal-
ly injured, and both your vehicle and
the trailer can be damaged if they
begin to move downhill.However, if you ever have to park
your trailer on a hill, here’s how to do
it:
1. Apply your brakes, but don’t shift
into gear.
2. Have someone place chocks (blocks of wood or metal intended
for this purpose) under the down-
hill sides of the trailer wheels.
3. When the wheel chocks are in place, release the brakes until the
chocks absorb the load.
4. Reapply the brakes. Apply your parking brake, and then shift to R
(Reverse) for a manual transaxle
or P (Park) for an automatic
transaxle.
5. Release the brakes.
When you are ready to leave after parking on a hill 1. With the manual transaxle in Neutral or automatic transaxle in P
(Park), apply your brakes and hold
the brake pedal down while you:
 Start your engine;
 Shift into gear; and
 Release the parking brake.
2. Slowly remove your foot from the brake pedal.
3. Drive slowly forward until the trail- er is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
WARNING
- Parking brake
It can be dangerous to get out of
your vehicle if the parking brake
is not firmly set or if the engine
is still running. In either case
the vehicle can move suddenly.
You or others could be serious-
ly or fatally injured.
WARNING
- Parking on a hill
Parking your vehicle on a hill
with a trailer attached is danger-
ous. It could cause serious
injury or death, should the trail-
er break lose, or should the trail-
er drag the vehicle downhill.
