Limitations of the system
The Smart Cruise Control System
may have limits to its ability to detect
distance to the vehicle ahead due to
road and traffic conditions.
On curves
• The Smart Cruise Control System
may not detect a moving vehicle in
your lane, and then your vehicle
could accelerate to the set speed.
Also, the vehicle speed will
decrease when the vehicle ahead
is recognized suddenly.
• Select the appropriate set speed
on curves and apply the brakes or
accelerator pedal if necessary.Your vehicle speed can be reduced
due to a vehicle in the adjacent lane.
Apply the accelerator pedal and
select the appropriate set speed.
Check to be sure that the road con-
ditions permit safe operation of the
Smart Cruise Control.
OAE056101
OAE056100
When using the Cruise Control
mode, you must manually
adjust the distance to other
vehicles by depressing the
accelerator or brake pedal. The
system does not automatically
adjust the distance to vehicles
in front of you.
WARNING

5-110
To prevent engine and/or trans-
mission overheating:
• When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the engine
coolant temperature gauge to
ensure the engine does not
overheat. If the needle of the
coolant temperature gauge
moves towards "H" (HOT), pull
over and stop as soon as it is
safe to do so, and allow the
engine to idle until it cools
down. You may proceed once the
engine has cooled sufficiently.
• If you tow a trailer with the max-
imum gross vehicle weight and
maximum trailer weight, it can
cause the engine or transmis-
sion to overheat. When driving
in such conditions, allow the
engine to idle until it cools
down. You may proceed once the
engine or transmission has
cooled sufficiently.
(Continued)(Continued)
• When towing a trailer, your vehi-
cle speed may be much slower
than the general flow of traffic,
especially when climbing an
uphill grade. Use the right hand
lane when towing a trailer on an
uphill grade. Choose your vehicle
speed according to the maximum
posted speed limit for vehicles
with trailers, the steepness of the
grade, and your trailer weight.
• Vehicles equipped with a dual
clutch transmission when tow-
ing a trailer on steep grades,
need to be aware that the clutch
in the transmission could over-
heat.
When the clutch is overheated,
the safe protection mode
engages. If the safe protection
mode engages, the gear posi-
tion indicator on the cluster
blinks with a chime sound.
(Continued)(Continued)
At this time, a warning message
will appear on the LCD display
and driving may not be smooth.
If you ignore this warning, the
driving condition may become
worse.
To return to normal driving con-
ditions, stop the vehicle on a flat
road and apply the foot brake for
a few minutes before driving off.

IF THE ENGINE WILL NOT START
What to do in an emergency
Hybrid vehicle
• Be sure the shift lever is in P
(Park). The vehicle starts only
when the shift lever is in P (Park).
• This vehicle does not have a regu-
lar 12V battery that needs periodic
replacement. It is lithium ion poly-
mer type integrated into the HEV
high voltage battery. The vehicle
has a 12V battery protection sys-
tem that cuts 12V battery from
vehicle draw to prevent full dis-
charge. If vehicle will not start, first
try pressing the 12V Battery Reset
switch (left side of the steering
wheel near the fuel door open
switch) to reconnect the 12V bat-
tery, but you must start vehicle
within 15 seconds of pressing the
12V Battery Reset switch. After
starting vehicle, operate the vehi-
cle safely outdoors in ready mode
stopped and/or drive it for 30 min-
utes total to charge the 12V battery
fully.• Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, we
recommend that you call an author-
ized HYUNDAI dealer for assistance.
Plug-in hybrid vehicle
• Be sure the shift lever is in P
(Park). The vehicle starts only
when the shift lever is in P (Park).
• Check the battery connections to
be sure they are clean and tight.
• Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle.See instructions for
"Jump Starting" provided in this
chapter.
• Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, we
recommend that you call an author-
ized HYUNDAI dealer for assistance.Push or pull starting the vehicle
may cause the catalytic convert-
er to overload which can lead to
damage to the emission control
system.
CAUTION
Push or pull starting the vehicle
may cause the catalytic con-
verter to overload which can
lead to damage to the emission
control system.
CAUTION

What to do in an emergency
Before jump starting
This vehicle does not have a regular
12V battery that needs periodic
replacement. It is lithium ion polymer
type integrated into the HEV high
voltage battery. The vehicle has a
12V battery protection system that
cuts 12V battery from vehicle draw to
prevent full discharge.
Using the 12V battery reset
switch
1. Press the 12V Battery Reset
switch to reconnect the 12V bat-
tery.
2. Start the vehicle within 15 sec-
onds of pressing the 12V Battery
Reset switch.
3. After starting vehicle ( indica-
tor on), operate the vehicle safely
outdoors in ready mode stopped
and/or drive it for 30 minutes total
to charge the 12V battery fully.If you do not start the vehicle imme-
diately after pressing the 12V Battery
Reset switch, the power of 12V bat-
tery is automatically disconnected
after few seconds to save the 12V
battery from additional discharge. If
the 12V battery is disconnected prior
to starting the vehicle, press the 12V
Battery Reset switch again and then
immediately start the vehicle as
explained.
Repeated use of the 12V Battery
Reset switch without a sufficient
engine ON cycle (30 Min+) may
cause over discharge of the 12V bat-
tery, which will prevent the vehicle
from starting. If the 12V battery is
over discharged to a point that the
reset does not work, try to jump-start
the vehicle.
Information
After starting the vehicle ( indica-
tor on), the 12V battery is being
charged whether the engine is running
or not. Although there is no engine-
sound, it is unnecessary to depress the
accelerator pedal.

•The TPMS cannot alert you to
severe and sudden tire dam-
age caused by external fac-
tors such as nails or road
debris.
•If you feel any vehicle instabil-
ity, immediately take your foot
off the accelerator, apply the
brakes gradually with light
force, and slowly move to a
safe position off the road.
WARNING
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS) com-
ponents may interfere with the
system's ability to warn the driv-
er of low tire pressure condi-
tions and/or TPMS malfunctions.
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS) com-
ponents may void the warranty
for that portion of the vehicle.
WARNING
For EUROPE
•Do not modify the vehicle; it
may interfere with the TPMS
function.
•The wheels on the market do
not have a TPMS sensor.

ized HYUNDAI dealer.
•If you use the wheels on the mar-
ket, use a TPMS sensor approved
by a HYUNDAI de
aler. If your
vehicle is not equipped with a
TPMS sensor or TPMS does not
work properly, you may fail the
