WARNING- Check sur-
roundings
Always check the surrounding
areas near your vehicle for peo-
ple, especially children, before
putting a vehicle into D (Drive)
or R (Reverse).
WARNING- Fire risk
When you intend to park or stop
the vehicle with the engine on,
be careful not to depress the
accelerator pedal for a long
period of time. It may overheat
the engine or exhaust system
and cause fire.WARNING- Loose
objects
Securely store items in your
vehicle. When you make a sud-
den stop or turn the steering
wheel rapidly, loose objects
may drop on the floor and it
could interfere with the opera-
tion of the foot pedals, possibly
causing an accident.WARNING- Driving while
intoxicated
Do not drive while intoxicated.
Drinking and driving is danger-
ous. Even a small amount of
alcohol will affect your reflexes,
perceptions and judgment.
Driving while under the influ-
ence of drugs is as dangerous
as or more dangerous than driv-
ing drunk.

Driving your vehicle
Transmission high temperature
Under certain conditions, such as
repeated stop-and-go launches on
steep grades, sudden take off or
acceleration, or other harsh driving
conditions, the transmission clutch
temperatures will increase exces-
sively.
When the clutch is overheated, the
safe protection mode engages and
the gear position indicator on the
cluster blinks with a chime. In this
situation, “Transmission temp. is
high! Stop safely” warning mes-
sage will appear on the LCD dis-
play, and driving may not be
smooth. If this occurs, pull over to a safe
location, stop the vehicle with the
engine running, apply the brakes,
shift the vehicle to P (Park), and
allow the transmission to cool.
If you ignore this warning, the driv-
ing condition may become worse.
You may experience abrupt shifts,
frequent shifts, or jerkiness. To
return to the normal driving condi-
tion, stop the vehicle and apply the
foot brake or shift into P (Park).
Then allow the transmission to cool
for a few minutes with the engine
on before driving off.
When possible, drive the vehicle
smoothly.

5. Move the shift lever.
6. Remove the tool from the shiftlock
override access hole then install
the cap.
7. We recommend that the system
be inspected by an authorized Kia
dealer.Ignition key interlock system
(if equipped)
The ignition key cannot be removed
unless the shift lever is in the P
(Park) position.
ENGINE START/STOP button inter-
lock system (if equipped)
The ENGINE START/STOP button
will not change to the OFF position
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
position with the accelerator pedal
depressed.
Never move the shift lever into P
(Park) when the vehicle is in motion.
Be sure the car is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).
Never take the car 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 mal-
function. 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 the car.
Slow down before shifting to a
lower gear. Otherwise, the lower
gear may not be engaged.

527
Driving your vehicle
Always use the parking brake. Do
not depend on placing the
transaxle in P (Park) to keep the
car from moving.
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.
Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the
accelerator pedal.
CAUTION
- Holding the Vehicle Using
Accelerator Pedal
Do not attempt to hold your
vehicle on a hill by applying the
accelerator pedal. This can
cause your clutch and transmis-
sion to be damaged as a result
of overheating.
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle
free by moving it forward and
backward. Do not attempt this
procedure if people or objects
are anywhere near the vehicle.
During the rocking operation the
vehicle may suddenly move for-
ward of backward as it becomes
unstuck, causing injury or dam-
age to nearby people or objects.
WARNING
When driving uphill or downhill,
always shift to D (Drive) for driv-
ing forward or shift to R
(Reverse) for driving backwards,
and check the gear position
indicated on the cluster before
driving.
Driving in the opposite direction
of the selected gear can lead to
a dangerous situation by shut-
ting off the engine and affecting
the braking performance.

To release EPB (Electronic Parking
Brake) automatically:
Shift lever in P (Park)
With the engine running depress
the brake pedal and shift out of P
(Park) to R (Reverse) or D (Drive).
Shift lever in N (Neutral)
With the engine running depress
the brake pedal and shift out of N
(Neutral) to R (Reverse) or D
(Drive).
Depress the accelerator pedal
slowly when the following condi-
tions are satisfied:
1. Start the engine.
2. Fasten the driver's seat belt.
3. Close the driver's door, engine
hood and liftgate.
4. The shift lever is in R (Rear), D
(Drive) or manual mode.
Make sure the brake warning light
goes off.✽ ✽
NOTICE
• For your safety, you can engage
the EPB even though the ignition
switch or ENGINE START/STOP
button is in the OFF position, but
you cannot release it.
• For your safety, depress the brake
pedal and release the parking
brake manually with the EPB
switch when you drive downhill or
when backing up the vehicle.
EPB (Electronic Parking Brake) may
be automatically applied when:
The EPB is overheated
Requested by other systems
The hybrid system is turned off
with the EPB applied
✽ ✽
NOTICE
• If Auto Hold is operating (Green
light), EPB is applied automatical-
ly when the hybrid system is
turned off.
• If Auto Hold is in ready position
(White light), EPB is applied auto-
matically after 1 second from the
hybrid system off timing. In this
case, if the EPB switch is pressed
within 1 second, the EPB will not
be applied.
CAUTION
If the parking brake warning
light is still on even though
the EPB has been released,
have the system checked by
an authorized Kia dealer.
Do not drive your vehicle with
the EPB applied. It may cause
excessive brake pad and
brake rotor wear.

Driving your vehicle
Good braking practices
Check to be sure the parking brake
is not engaged and the parking
brake indicator light is out before
driving away.
Driving through water may get the
brakes wet. They can also get wet
when the vehicle is washed. Wet
brakes can be dangerous! Your
vehicle will not stop as quickly if the
brakes are wet. Wet brakes may
cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action
returns to normal, taking care to
keep the vehicle under control at all
times. If the braking action does not
return to normal, stop as soon as it
is safe to do so and call an author-
ized Kia dealer for assistance.
Don't coast down hills with the
vehicle out of gear. This is extreme-
ly hazardous. Keep the vehicle in
gear at all times, use the brakes to
slow down, then shift to a lower
gear so that engine braking will
help you maintain a safe speed. Don't "ride" the brake pedal.
Resting your foot on the brake
pedal while driving can be danger-
ous because the brakes might
overheat and lose their effective-
ness. It also increases the wear of
the brake components.
If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe place.
If your vehicle is equipped with a
dual clutch transmission, don't let
your vehicle creep forward. To
avoid creeping forward, keep your
foot firmly on the brake pedal when
the vehicle is stopped.
Be cautious when parking on a hill.
Firmly engage the parking brake
and place the shift lever in P (Dual
clutch transmission). If your vehicle
is facing downhill, turn the front
wheels into the curb to help keep
the vehicle from rolling.If your vehicle is facing uphill, turn
the front wheels away from the
curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to
keep the vehicle from rolling, block
the wheels.
Under some conditions your park-
ing brake can freeze in the
engaged position. This is most like-
ly to happen when there is an
accumulation of snow or ice
around or near the rear brakes or if
the brakes are wet. If there is a risk
that the parking brake may freeze,
apply it only temporarily while you
put the shift lever in P (Dual clutch
transmission) and block the rear
wheels so the vehicle cannot roll.
Then release the parking brake.
Do not hold the vehicle on an
incline with the accelerator pedal.
This can cause the transaxle to
overheat. Always use the brake
pedal or parking brake.

Your 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 miles (kilometers) you can get
from a gallon (liter) 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:
Drive smoothly. Accelerate at a
moderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
the traffic so you don't have to
change speeds unnecessarily.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear.
Drive at a moderate speed. The
faster you drive, the more fuel your
vehicle uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption. Don't "ride" the brake pedal. This
can increase fuel consumption and
also increase wear on these com-
ponents. In addition, driving with
your foot resting on the brake pedal
may cause the brakes to overheat,
which reduces their effectiveness
and may lead to more serious con-
sequences.
Take care of your tires. Keep them
inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are
aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
chapter 8. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
chapter 8 for details).
Keep your vehicle clean. For maxi-
mum service, your vehicle should
be kept clean and free of corrosive
materials. It is especially important
that mud, dirt, ice, etc. not be
allowed to accumulate on the
underside of the vehicle. This extra
weight can result in increased fuel
consumption and also contribute to
corrosion.
Travel lightly. Don't carry unneces-
sary weight in your vehicle. Weight
reduces fuel economy.
Don't let the engine idle longer
than necessary. If you are waiting
(and not in traffic), turn off your
engine and restart only when
you're ready to go.
