Driving your vehicle
STARTING THE ENGINE 1. Make sure the parking brake is
applied.
2.Manual Transaxle- Depress the
clutch pedal fully and shift the
transaxle into Neutral. Keep the clutch
pedal depressed while turning the
ignition switch to the start position.
The starter will not operate if the
clutch pedal is not fully depressed.
Automatic Transaxle- Place the
transaxle shift lever in P (Park).
Depress the brake pedal fully.
You can also start the engine when
the shift lever is in the N (Neutral)
position.
3. Turn the ignition switch to START and
hold it there until the engine starts (a
maximum of 10 seconds), then
release the key.
4. In extremely cold weather (below
0°F / -18°C) or after the vehicle has
not been operated for several days, let
the engine warm up without depress-
ing the accelerator.
Whether the engine is cold or warm, it
should be started without depressing
the accelerator.✽ ✽
NOTICEDo not engage the starter for more than
10 seconds. If the engine stalls or fails to
start, wait 5 to 10 seconds before re-
engaging the starter. Excessive or
improper use of the starter may damage
it. The starter will not operate if:
Manual Transaxle- the clutch pedal is
not fully depressed.
Automatic Transaxle- the shift lever
is NOT in the P (Park) or N (Neutral)
position.
WARNING
- Ignition key
• Never turn the ignition switch to
LOCK or ACC while the vehicle is
moving. This would result in loss
of directional control and braking
function, which could cause an
accident or collision.
Before leaving the driver’s seat,
always make sure the shift lever
is engaged in 1
stgear for manual
transaxle or P (Park) for automat-
ic transaxle. Then, set the parking
brake fully and shut the engine
off. Unexpected and sudden vehi-
cle movement may occur if these
precautions are not taken.
Never reach for the ignition
switch, or any other controls
through the steering wheel while
the vehicle is in motion. The pres-
ence of your hand or arm in this
area could cause a loss of vehicle
control, an accident and serious
bodily injury or death.
Do not place any movable objects
around the driver’s seat as they
may move while driving, interfere
with the driver and lead to an
accident.
CAUTION -
Stall
If the engine stalls while you are in
motion, do not attempt to move the
shift lever to the P (Park) position. If
traffic and road conditions permit,
you may put the shift lever in the N
(Neutral) position while the vehicle
is still moving and turn the ignition
switch to the START position in an
attempt to restart the engine.
WARNING
Always wear appropriate shoes
when operating your vehicle.
Unsuitable shoes (high heels, ski
boots,etc.) may interfere with your
ability to use the brake and acceler-
ator pedal, and the clutch (if
equipped).

Driving your vehicle4 4
Manual transaxle operationThe manual transaxle has five forward
gears.
Press the clutch pedal down fully while
shifting, then release it slowly.
The gearshift lever must be returned to
the neutral position before shifting into R
(Reverse). The ring located immediately
below the shift knob must be pulled
upward while moving the shift lever to the
R position.Make sure the vehicle is completely
stopped before shifting into R (Reverse).
Never operate the engine with the
tachometer (rpm) in the red zone.✽ ✽
NOTICEWhen downshifting from fifth gear to
fourth gear, caution should be taken not
to inadvertently press the gear shift
lever sideways in such a manner that
second gear is engaged. Such a drastic
downshift may cause the engine speed to
increase to the point that the tachometer
will enter the red-zone. Such over-
revving of the engine may possibly cause
engine damage.
MANUAL TRANSAXLE (IF EQUIPPED)
OMG045003N
The ring (1) must be pulled up while moving the shift lever. The shift lever can be moved without pulling the ring (1).

Driving your vehicle
To shift into reverse, rest the lever in
neutral for at least 3 seconds after your
car is completely stopped. Then move
the lever into the reverse position.
During cold weather, shifting may be
difficult until the transaxle lubricant has
warmed up. This is normal and not
harmful to the transaxle.
If you've come to a complete stop and
it's hard to shift into 1st or R (Reverse),
put the shift lever in N (Neutral) posi-
tion and release the clutch. Press the
clutch pedal back down, and then shift
into 1st or R (Reverse) gear position.
✽ ✽
NOTICETo avoid premature clutch wear and
damage, do not drive with your foot
resting on the clutch pedal. Also, don’t
use the clutch to hold the vehicle
stopped on an uphill grade, while wait-
ing for a traffic light, etc.
DownshiftingWhen you must slow down in heavy traf-
fic or while driving up steep hills, down-
shift before the engine starts to labor.
Downshifting reduces the chance of
stalling and gives better acceleration
when you again need to increase your
speed. When the vehicle is traveling
down steep hills, downshifting helps
maintain safe speed and prolongs brake
life.
WARNING
- Manual
transaxle
Before leaving the driver’s seat,
always set the parking brake fully
and shut the engine off. Then make
sure the transaxle is shifted into 1
st
gear when the vehicle is parked on
a level or uphill grade, and shifted
into R (Reverse) on a downhill
grade. Unexpected and sudden
vehicle movement can occur if
these precautions are not followed
in the order identified.

Driving your vehicle
To cancel cruise control, do one
of the following: Press the brake pedal.
Press the clutch pedal with a manual
transaxle or shift into N (Neutral) with an
automatic transaxle.
Press the CANCEL switch located on
the steering wheel.
Press the COAST/SET and
RES/ACCEL switches at the same
time.Each of these actions will cancel cruise
control operation (the “SET” indicator
light in the instrument cluster will go
OFF), but it will not turn the system off. If
you wish to resume cruise control opera-
tion, press the RES/ACCEL switch locat-
ed on your steering wheel. You will return
to your previously preset speed.
To turn cruise control off, do one
of the following: Push the CRUISE ON/OFF button on
the steering wheel (the CRUISE indi-
cator light in the instrument cluster will
go OFF).
Turn the ignition off.Both of these actions cancel cruise con-
trol operation. If you want to resume
cruise control operation, repeat the steps
provided in “To Set Cruise Control
Speed” on the previous page.
To increase cruise control set
speed:Follow either of these procedures:
Press the RES/ACCEL switch and hold
it. Your vehicle will accelerate. Release
the switch at the speed you want.

Maintenance14 7BRAKE FLUID Checking brake fluid level Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If your vehicle is equipped with a manual
transaxle, brake fluid is used as clutch
fluid.If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings.
If the fluid level is excessively low, have
the brake system checked by an author-
ized Kia dealer.
Use only the specified brake fluid. (Refer
to “Recommended Lubricants” later in
this section.)
Never mix different types of fluid.
✽ ✽
NOTICEDo not allow brake fluid to contact the
vehicle's body paint, as paint damage
will result. Brake fluid, which has been
exposed to open air for an extended time
should never be used as its quality can-
not be guaranteed. It should be thrown
out. Don't put in the wrong kind of fluid.
A few drops of mineral-based oil, such
as engine oil, in your brake/clutch sys-
tem can damage brake/clutch system
parts.
WARNING -
Brake fluid
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. If
brake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
WARNING -
Loss of brake
fluid
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized Kia dealer.

LUBRICANT SPECIFICATIONSRecommended lubricants To help achieve proper engine and powertrain performance and
durability, use only lubricants of the proper quality. The correct
lubricants also help promote engine efficiency that results in
improved fuel economy.
Engine oils labeled Energy Conserving Oil are now available.
Along with other additional benefits, they contribute to fuel
economy by reducing the amount of fuel necessary to over-
come engine friction. Often, these improvements are difficult to
measure in everyday driving, but in a year’s time, they can offer
significant cost and energy savings.
Recommended SAE viscosity number ✽ ✽
NOTICEAlways be sure to clean the area around any filler plug, drain
plug, or dipstick before checking or draining any lubricant.
This is especially important in dusty or sandy areas and when
the vehicle is used on unpaved roads. Cleaning the plug and
dipstick areas will prevent dirt and grit from entering the
engine and other mechanisms that could be damaged. Engine oil viscosity (thickness) has an effect on fuel economy
and cold weather operating (starting and oil flow). Lower vis-
cosity engine oils can provide better fuel economy and cold
weather performance, however, higher viscosity engine oils are
required for satisfactory lubrication in hot weather. Using oils of
any viscosity other than those recommended could result in
engine damage.
When choosing an oil, consider the range of temperature your
vehicle will be operated in before the next oil change. Proceed
to select the recommended oil viscosity from the chart.
