Detecting Sensors
ODN8069031L
The rear corner radars are the sensors
inside the rear bumper for detecting the
side and rear areas. Always keep the rear
bumper clean for proper operation of the
system.
CAUTION
• The system may not work properly
when the bumper has been
damaged, or if the rear bumper has
been replaced or repaired.
• The system may turn off due to
strong electromagnetic waves.
• Always keep the sensors clean.
• NEVER arbitrarily disassemble the
sensor component nor apply any
impact on the sensor component.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly moved
out of proper alignment, the system
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• Do not apply foreign objects such as
a bumper sticker or a bumper guard
near the radar sensor or apply paint
to the sensor area. Doing so may
adversely affect the performance of
the sensor.

Tire chains
ODN8069077L
Since the sidewalls of radial tires are
thinner than other types of tires, they
may be damaged by mounting some
types of tire chains on them. Therefore
the use of snow tires is preferred over the
use of tire chains.
If the road and weather conditions
require the use of tire chains, be sure to
use tire chains that have been properly
selected for the size of tire on your
HYUNDAI vehicle.
Be sure to follow the guidelines and
installation instructions provided from
the tire chain manufacturer.
Damage to your vehicle caused by
improper tire chain use is not covered by
your vehicle manufacturer’s warranty.
WARNING
The use of tire chains may adversely
affect vehicle handling:
• Drive less than 20 mph (30 km/h)
or the chain manufacturer's
recommended speed limit,
whichever is lower.
• Drive carefully and avoid bumps,
holes, sharp turns, and other road
hazards, which may cause the
vehicle to bounce.
• Avoid sharp turns or locked wheel
braking.
Information
• Install tire chains on both left and right
front tires. It should be noted that
installing tire chains on the tires will
provide a greater driving force, but will
not prevent side skids.
• Do not install studded tires without
first checking local, state and municipal
regulations for possible restrictions
against their use.

Check spark plugs and ignition
system
Inspect your spark plugs as described in
chapter 8 and replace them if necessary.
Also check all ignition wiring and
components to be sure they are not
cracked, worn or damaged in any way.
Use approved window washer anti-
freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types
of antifreeze as these may damage the
paint finish.
Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely 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
the parking brake may freeze, apply
it only temporarily while you put the
gear selector lever in P and block the
rear wheels so the car cannot roll. Then
release the parking brake.
Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in severe winter conditions where this
may happen, you should periodically
check underneath the car to be sure the
movement of the front wheels and the
steering components is not obstructed.
Don't place foreign objects
or materials in the engine
compartment
Placement of foreign object or materials
which prevent cooling of the engine, in
the engine compartment, may cause a
failure or combustion. The manufacturer
is not responsible for the damage caused
by such placement.
To keep locks from freezing
To keep the locks from freezing, squirt
an approved de-icer fluid or glycerine
into the key opening. If a lock is covered
with ice, squirt it with an approved de-
icing fluid to remove the ice. If the lock
is frozen internally, you may be able to
thaw it out by using a heated key. Handle
the heated key with care to avoid injury.

Emergency situations
7-4
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
ODN8HQ019028
1. Press the 12V Battery Reset switch to
reconnect the 12V battery.
2. Start the vehicle within 15 seconds of
pressing the 12V Battery Reset switch.
3. After starting the vehicle
( indicator 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
immediately after pressing the 12V
Battery Reset switch, the power of 12V
battery 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 battery, 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
( indicator 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 following items may need to be reset
after the battery has been discharged or
the battery has been disconnected.
See chapter 4 and 5 for:
• Power Windows
• Trip Computer
• Climate Control System
• Clock
• Audio System
• Sunroof
IF THE 12 VOLT BATTERY IS DISCHARGED

Emergency situations
7-8
WARNING
Never remove the engine coolant cap and/or inverter
coolant cap or the drain plug
while the engine and radiator
are hot.
Hot coolant and steam may blow out
under pressure, causing serious injury.
Turn the hybrid system off and wait until
the engine cools down. Use extreme
care when removing the engine coolant
cap and/or inverter coolant cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back while the pressure is
released from the cooling system. When
you are sure all the pressure has been
released, press down on the cap, using
a thick towel, and continue turning
counterclockwise to remove it.
CAUTION
• Serious loss of coolant indicates a
leak in the cooling system and should
be checked as soon as possible by an
authorized HYUNDAI dealer.
• When the engine overheats from
low engine coolant, suddenly adding
engine coolant may cause cracks
in the engine. To prevent damage,
add engine coolant slowly in small
quantities.
