Use of MTBE
KIA recommends avoiding fuels contain-
ing MTBE (Methyl Tertiary Butyl Ether)
over 15.0% vol. (Oxygen Content 2.7%
weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapor lock or hard starting.
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system.
Fuel Additives
KIA recommends that you use good
quality gasolines treated with detergent
additives such as TOP TIER Detergent
Gasoline, which help prevent deposit for-
mation in the engine. These gasolines
will help the engine run cleaner and
enhance performance of the Emission
Control System. For more information on
TOP TIER Detergent Gasoline, please
go to the website (www
.toptiergas.com).
For customers who do not use TOP Tier
Detergent Gasoline regularly, and have
problems starting or the engine does not
run smoothly, additives that you can buy
separately may be added to the gasoline.
If TOP TIER Detergent Gasoline is not
available, one bottle of additive added to
the fuel tank at every 12,000 km or every
engine oil change is recommended.
Additives are available from your author-
ized KIA dealer along with information on
how to use them. Do not mix other addi-
tives.
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
Observe all regulations regarding reg- istration and insurance.
Determine that acceptable fuel is avail- able. No special break-in period is needed. By
following a few simple precautions for the
first 1,000 km (600 miles) you may add to
the performance, economy and life of
your vehicle.
Do not race the engine.
While driving, keep your engine speed
(rpm, or revolutions per minute)
between 2,000 rpm and 4,000 rpm.
Do not maintain a single speed for long periods of time, either fast or slow.
Varying engine speed is needed to
properly break-in the engine.
Avoid hard stops, except in emergen- cies, to allow the brakes to seat prop-
erly.
Don't let the engine idle longer than 3 minutes at one time.
Don't tow a trailer during the first 2,000 km (1,200 miles) of operation.
CAUTION
Your New Vehicle Limited Warrantymay not cover damage to the fuelsystem and any performance prob- lems that are caused by the use offuels containing methanol or fuelscontaining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol.(Oxygen Content 2.7% weight.)

Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and add
fluid as required. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are found, the warning light remains on or
the brakes do not operate properly.
Have the vehicle towed to any author-
ized KIA dealer for a brake system
inspection and necessary repairs.
Your vehicle is equipped with dual-diago-
nal braking systems. This means you still
have braking on two wheels even if one
of the dual systems should fail. With only
one of the dual systems working, more
than normal pedal travel and greater
pedal pressure are required to stop the
vehicle. Also, the vehicle will not stop in
as short a distance with only a portion of
the brake system working. If the brakes
fail while you are driving, shift to a lower
gear for additional engine braking and
stop the vehicle as soon as it is safe to do
so. To check bulb operation, check whether
the parking brake and brake fluid warning
light illuminates when the ignition switch
is in the ON position.Front fog light indicator
(if equipped)
This indicator comes on when the front
fog lights are ON.
Shift pattern indicator (if equipped)
The indicator displays which automatic
transaxle shift position is selected.
WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorized KIA dealer.

Non-operational conditions of
rear parking assist system
The rear parking assist system may
not operate properly when:
1. Moisture is frozen to the sensor. (It will
operate normally when the moisture
has been cleared.)
2. The sensor is covered with foreign matter, such as snow or water, or the
sensor cover is blocked. (It will operate
normally when the material is removed
or the sensor is no longer blocked.)
3. Driving on uneven road surfaces (unpaved roads, gravel, bumps, gradi-
ent).
4. Objects generating excessive noise (vehicle horns, loud motorcycle
engines, or truck air brakes) are within
range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones are within range of the sensor.
7. The sensor is covered with snow.
8. Trailer towing The detecting range may decrease
when:
1. The sensor is stained with foreign mat-
ter such as snow or water. (The sens-
ing range will return to normal when
removed.)
2. Outside air temperature is extremely hot or cold.
The following objects may not be rec-
ognized by the sensor:
1. Sharp or slim objects such as ropes, chains or small poles.
2. Objects which tend to absorb the sen- sor frequency such as clothes, spongy
material or snow.
3. Undetectable objects smaller than 1 m (40 in.) in height and narrower than 14
cm (6 in.) in diameter.
Rear parking assist system pre-
cautions
The rear parking assist system maynot sound sequentially depending on
the speed and shapes of the objects
detected.
The rear parking assist system may malfunction if the vehicle bumper
height or sensor installation has been
modified or damaged. Any non-factory
installed equipment or accessories
may also interfere with the sensor per-
formance.
The sensor may not recognize objects less than 40 cm (15 in.) from the sen-
sor, or it may sense an incorrect dis-
tance. Use caution.
When the sensor is frozen or stained with snow, dirt, or water, the sensor
may be inoperative until the stains are
removed using a soft cloth.
Do not push, scratch or strike the sen- sor. Sensor damage could occur.

Good driving practices
Never take the vehicle out of gear and
coast down a hill. This is extremely
hazardous. Always leave the vehicle in
gear.
Don't "ride" the brakes. This can cause them to overheat and malfunction.
Instead, when you are driving down a
long hill, shift to a lower gear. When
you do this, engine braking will help
slow down the vehicle.
Slow down before shifting to a lower gear. This will help avoid over-revving
the engine, which can cause damage.
Slow down when you encounter cross winds. This gives you much better con-
trol of your vehicle.
Be sure the vehicle is completely stopped before you attempt to shift into
R (Reverse). The transaxle can be
damaged if you do not. To shift into R
(Reverse), depress the clutch, move
the shift lever to neutral, wait three sec-
onds, then shift to the R (Reverse)
position.
Exercise extreme caution when driving on a slippery surface. Be especially
careful when braking, accelerating or
shifting gears. On a slippery surface,
an abrupt change in vehicle speed can
cause the drive wheels to lose traction
and the vehicle to go out of control.WARNING
Always buckle-up! In a collision,
an unbelted occupant is signifi-
cantly more likely to be seriously
injured or killed than a properly
belted occupant.
Avoid high speeds when corner- ing or turning.
Do not make quick steering wheel movements, such as sharp
lane changes or fast, sharp turns.
The risk of rollover is greatly increased if you lose control of
your vehicle at highway speeds.
Losing control often occurs if two or more wheels drop off the road-
way and the driver oversteers to
reenter the roadway.
In the event your vehicle leaves the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
Never exceed posted speed lim- its.

For smooth operation, depress the brake
pedal when shifting from N (Neutral) to aforward or reverse gear. Transaxle ranges
The indicator light in the instrument clus-
ter displays the shift lever position when
the ignition switch is in the ON position.
P (Park)
Always come to a complete stop before
shifting into P (Park). This position locks
the transaxle and prevents the front
wheels from rotating.
WARNING- Automatic
transaxle
Always check the surrounding
areas near your vehicle for peo-
ple, especially children, before
shifting a shift lever into D (Drive)
or R (Reverse).
Before leaving the driver’s seat, always make sure the shift lever
is in the P (Park) position; then
set the parking brake fully and
shut the engine off. Unexpected
and sudden vehicle movement
can occur if these precautions
are not followed in the order iden-
tified.
CAUTION
To avoid damage to your transaxle, do not accelerate theengine in R (Reverse) or any for-ward gear position with thebrakes on.
When stopped on an upgrade, do not hold the vehicle with enginepower. Use the service brake orthe parking brake.
Do not shift from N (Neutral) or P (Park) into D (Drive), or R(Reverse) when the engine isabove idle speed.

517
Driving your vehicle
R (Reverse)
Use this position to drive the vehicle
backward.
N (Neutral)
The wheels and transaxle are not
engaged. The vehicle will roll freely even
on the slightest incline unless the parking
brake or service brakes are applied.D (Drive)
This is the normal forward driving posi-
tion. The transaxle will automatically shift
through a 6-gear sequence, providing the
best fuel economy and power.
For extra power when passing another
vehicle or climbing grades, depress the
accelerator fully, at which time the
transaxle will automatically downshift to
the next lower gear.
✽ ✽
NOTICE
Always come to a complete stop before
shifting into D.
WARNING
Shifting into P (Park) while the
vehicle is in motion will cause the
drive wheels to lock which will
cause you to lose control of the
vehicle.
Do not use the P (Park) position in place of the parking brake.
Always make sure the shift lever
is latched in the P (Park) position
and set the parking brake fully.
Never leave a child unattended in a vehicle.
CAUTION
The transaxle may be damaged ifyou shift into P (Park) while the vehicle is in motion.
CAUTION
Always come to a complete stopbefore shifting into or out of R (Reverse); you may damage thetransaxle if you shift into R(Reverse) while the vehicle is inmotion, except when “Rocking theVehicle” explained in this section.

Shift-lock override
If the shift lever cannot be moved from
the P (Park) into R (Reverse) position
with the brake pedal depressed, continue
depressing the brake, then do the follow-
ing:
1. Carefully remove the cap covering the
shift-lock access hole.
2. Insert a key (or screwdriver) into the access hole and press down on the
key (or screwdriver).
3. Move the shift lever.
4. Have your vehicle inspected by an authorized KIA dealer immediately.
Ignition key interlock system
The ignition key cannot be removed
unless the shift lever is in the P (Park)
position.
Good driving practices
Never move the shift lever from P(Park) or N (Neutral) to any other posi-
tion with the accelerator pedal
depressed.
Never move the shift lever into P (Park) when the vehicle is in motion.
Be sure the vehicle is completely stopped before you attempt to shift into
R (Reverse) or D (Drive).
Never take the vehicle out of gear and coast down a hill. This may be
extremely hazardous. Always leave the
car in gear when moving.
Do not "ride" the brakes. This can cause them to overheat and malfunc-
tion. Instead, when you are driving
down a long hill, slow down and shift to
a lower gear. When you do this, engine
braking will help slow down the vehicle.
Slow down before shifting to a lower gear. Otherwise, the lower gear may
not be engaged.
Always use the parking brake. Do not depend on placing the transaxle in P
(Park) to keep the vehicle from moving.

Moving up a steep grade from a stand-
ing start
To move up a steep grade from a stand-
ing start, depress the brake pedal, shift
the shift lever to D (Drive). Select the
appropriate gear depending on load
weight and steepness of the grade, and
release the parking brake. Depress the
accelerator gradually while releasing the
service brakes.

Driving your vehicle
Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces.
In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
BRAKE SYSTEM
(Continued)
When descending a long or steephill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
Wet brakes may impair the vehi- cle’s ability to sefely slow down;
the vehicle may also pull to one
side when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
Always, confirm the position of the brake and accelerator pedal
before driving. If you don't check
the position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It may
cause a serious accident.
WARNING- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.
WARNING- Brakes
Do not drive with your foot rest-ing on the brake pedal. This will
create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increased
stopping distances.

Disc brakes wear indicator
Your vehicle has disc brakes.
When your brake pads are worn and new
pads are required, you will hear a high-
pitched warning sound from your front
brakes or rear brakes. You may hear this
sound come and go or it may occur
whenever you depress the brake pedal.
Please remember that some driving con-
ditions or climates may cause a brake
squeal when you first apply (or lightly
apply) the brakes. This is normal and
does not indicate a problem with your
brakes.
Parking brake
Applying the parking brake
Foot type
To engage the parking brake, first apply
the foot brake and then depress the park-
ing brake pedal down as far as possible. Hand type
To engage the parking brake, first apply
the foot brake and then pull up the park-
ing brake lever as far as possible.
In addition it is recommended that when
parking the vehicle on a incline, the shift
lever should be in a low gear on manual
transaxle vehicles or in the P (Park) posi-
tion on automatic transaxle vehicles.
WARNING- Brake wear
This brake wear warning sound
means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking
performance, which could lead to a
serious accident.
CAUTION
To avoid costly brake repairs, do
not continue to drive with wornbrake pads.
Always replace brake pads as complete front or rear axle sets.
