Driving your vehicle
When the stop lamp fuse is blown,you can't start the hybrid system
normally. Replace the fuse with a
new one. If it is not possible, you can
start the hybrid system by pressing
the ENGINE START/STOP button
for 10 seconds while it is in the ACC
position. The engine can start with-
out depressing the brake pedal. But
for your safety always depress the
brake pedal before starting the
hybrid system.
Do not press the ENGINE START/
STOP button for more than 10 sec-
onds except when the stop lamp fuse
is blown.

513
Driving your vehicle
For smooth operation, depress thebrake pedal and the lock release but-ton when shifting from N (Neutral) toa forward or reverse gear.
When stopped on an incline, do not
hold the vehicle with the engine
power. Use the service brake or the
parking brake.
Transmission ranges
The indicator in the instrument clus-
ter displays the shift lever position
when the engine start/stop button is
in the ON position.
P (Park)
Always come to a complete stop
before shifting into P (Park). This
position locks the transmission and
prevents the drive wheels from rotat-
ing.
Shifting into P (Park) while the vehi-
cle is in motion will cause the drive
wheels to lock which will cause you
to lose control of the vehicle.
To shift from P (Park), you must
depress firmly on the brake pedal
and make sure your foot is off the
accelerator pedal.
If you have done all of the above
and still cannot shift the lever out of
P (Park), see "Shift-lock override" in
this chapter.
The shift lever must be in P (Park)
before turning the hybrid system off.
WARNING- Leaving
Vehicle
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. Do not use
the P position in place of the
parking brake. Always make
sure the shift lever is locked in
the P position and set the park-
ing brake fully. Unexpected and
sudden vehicle movement can
occur if these precautions are
not followed.
CAUTION- Transmission
To avoid damage to your trans- mission, do not accelerate theengine in R (Reverse) or any for-ward gear position with thebrakes on. The transmissionmay be damaged if you shiftinto P (Park) while the vehicle isin motion.

517
Driving your vehicle
Shift lock system
For your safety, the automatic trans-
mission has a shift lock system
which prevents shifting the transmis-
sion from P (Park) into R (Reverse)
unless the brake pedal is depressed.
To shift the transmission from P
(Park) into R (Reverse):
1. Depress and hold the brake pedal.
2. Start the hybrid system or turn theignition switch to the ON position.
3. Move the shift lever.
If the brake pedal is repeatedly
depressed and released with the
shift lever in the P (Park) position, a
chattering noise & vibration near the
shift lever may be heard. It is a nor-
mal condition. Shift-lock override
If the shift lever cannot be moved
from the P (Park) position into R
(Reverse) position with the brake
pedal depressed, continue depress-
ing the brake, then do the following:
1. Place the engine start/stop button
in the OFF position.
2. Apply the parking brake.
3. Carefully remove the cap (1) cov- ering the shift-lock release access
hole.
4. Insert a tool (e.g. flathead screw- driver) into the access hole and
press down on the tool.WARNING- Shifting from
park
Always fully depress the brake
pedal before and while shifting
out of the P (Park) position into
another position to avoid inad-
vertent motion of the vehicle
which could injure persons in
or around the vehicle.

Driving your vehicle
Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the hybrid system is not on or is
turned off while driving, the power
assist for the brakes will not work.
You can still stop your vehicle by
applying greater force to the brake
pedal than typical. The stopping dis-
tance, however, will be longer than
with power brakes.
When the hybrid system is not on,
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
necessary to maintain steering con-
trol on slippery surfaces.Wet brakes may impair the vehicle’s
ability to safely slow down; the vehi-
cle 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 fash-
ion after driving through deep water.
To dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
✽ ✽
NOTICE
Do not depress the brake pedal con-
tinuously without the " " indica-
tor ON. The battery may be dis-
charged.
BRAKE SYSTEM
WARNING- Steep hill
braking
Avoid continuous application of
the brakes when descending a
long or steep hill by shifting to a
lower gear. Continuous brake
application will cause the
brakes to overheat and could
result in a temporary loss of
braking performance.
WARNING- HEV driving down hill
Do not turn off the Hybrid sys-
tem while going down a hill. The
brake booster may not work
sufficiently and the braking dis-
tance may be longer.
CAUTION- Brake Pedal
Do not drive with your foot rest- ing on the brake pedal. This willcreate abnormally high braketemperatures which can causeexcessive brake lining and padwear.

Check the brake warning light by
pressing engine start/stop button ON
(do not start the hybrid system). This
light will be illuminated when the park-
ing brake is applied with the engine
start/stop button in the START or ON
position.
Before driving, be sure the parking
brake is fully released and the brake
warning light is off.
If the brake warning light remains on
after the parking brake is released
while the hybrid system is on, there
may be a malfunction in the brake sys-
tem. Immediate attention is necessary. If at all possible, cease driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only contin-
ue to drive the vehicle until you can
reach a safe location or repair shop.

tion is limited even though there is no
change in the ECO indicator.
When the coolant temperature is low:
The system will be limited until
engine performance becomes nor-
mal.
When driving up a hill: The system will be limited to gain
power when driving uphill because
the engine torque is restricted.

What to do in an emergency
If the engine stalls at a cross-
road or crossing
If the engine stalls at a crossroad or
crossing, set the shift lever in the N
(Neutral) position and then push the
vehicle to a safe place.
If you have a flat tire while
driving
If a tire goes flat while you are driv-
ing:
1. Take your foot off the acceleratorpedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause a loss of con-
trol. When the vehicle has slowed
to such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes. 2. When the vehicle is stopped, turn
on your emergency hazard flash-
ers, set the parking brake and put
the transmission in P (for
Automatic transmission.
3. Have all passengers get out of the vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
4. When changing a flat tire, follow the instruction provided later in
this section.
If the engine stalls while driv-
ing
1. Reduce your speed gradually,keeping a straight line. Move cau-
tiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the hybrid system again. If your vehicle will not start,
contact an authorized Kia dealer
or seek other qualified assistance.
✽ ✽NOTICE
If there was a check engine light and
loss of power or stall and if safe to do
so, wait at least 10 seconds to restart
the vehicle after it stalls. This may
reset the car so it will no longer run
at low power (limp home) condition.
