[Parking Distance Warning Indicators
may be displayed differently from
the actual detected location when
the obstacle is located between the
sensors.

[Parking Distance Warning indicator
may not occur sequentially depending
on vehicle speed or obstacle shape.

[ If Forward/Reverse Parking Distance
Warning needs repair, we recommend
that the function be inspected by a
HYUNDAI authorised repairer.

Assist may unnecessarily warn the driver
or assist with braking even if there are
no pedestrians or objects under the
following circumstances:

[Any non-factory equipment or
accessory is installed

[Your vehicle is unstable due to an
accident or other causes

[Bumper height or rear ultrasonic
sensor installation has been modified

[Your vehicle height is low or high
due to heavy loads, abnormal tyre
pressure, etc.

CAUTION
Take the following precautions to
maintain optimal performance of the
detecting sensors:

[Always keep the rear view camera
and rear ultrasonic sensors clean.

[Do not use any cleanser containing
acid or alkaline detergents when
cleaning the rear view camera lens.
Use only a mild soap or neutral
detergent, and rinse thoroughly with
water.

[Do not spray the rear view camera or
the rear ultrasonic sensors or their
surrounding area directly with a
high pressure washer. It may cause
the rear view camera or the rear
ultrasonic sensors to malfunction.

[Do not apply objects, such as a
bumper sticker or a bumper guard,
near the rear view camera or rear
ultrasonic sensors or apply paint to
the bumper. Doing so may adversely
affect the performance of the
function.

[Never disassemble or apply impact
on the rear view camera or the rear
ultrasonic sensors components.

[Do not apply unnecessary force on
the rear view camera or the rear
ultrasonic sensors. The function
may not operate properly if the rear
view camera or the rear ultrasonic
sensor(s) is forcibly moved out of
proper alignment. We recommend
that the vehicle be inspected by a
HYUNDAI authorised repairer.

Emergency situations
Jump starting can be dangerous if done
incorrectly. Follow the jump starting
procedure in this section to avoid serious
injury or damage to your vehicle. If in
doubt about how to properly jump start
your vehicle, we strongly recommend
that you have a service technician or
towing service do it for you.
WARNING
To prevent SERIOUS INJURY or DEATH
to you or bystanders, always follow
these precautions when working near
or handling the battery:
Always read and follow
instructions carefully when
handling a battery.
Wear eye protection designed
to protect the eyes from acid
splashes.
Keep all flames, sparks, or
smoking materials away from
the battery.
Hydrogen is always present in
battery cells, is highly
combustible, and may explode
if ignited.
Keep batteries out of reach of
children.
Batteries contain sulfuric acid
which is highly corrosive. Do
not allow acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush your
eyes with clean water for at least 15
minutes and get immediate medical
attention. If acid gets on your skin,
thoroughly wash the area. If you
feel pain or a burning sensation, get
medical attention immediately.

[When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak. Lift with a
battery carrier or with your hands on
opposite corners.

[Do not attempt to jump start your
vehicle if your battery is frozen.

[NEVER attempt to recharge the
battery when the vehicle’s battery
cables are connected to the battery.

[The electrical ignition system works
with high voltage. NEVER touch these
components with the engine running
or when the ignition switch is in the
ON position.

[Do not allow the (+) and (-) jumper
cables to touch. It may cause sparks.

[The battery may rupture or explode
when you jump start with a low or
frozen battery.
NOTICE
To prevent damage to your vehicle:

[Only use a 12-volt power supply
(battery or jumper system) to jump
start your vehicle.

[Do not attempt to jump start your
vehicle by push-starting.
JUMP STARTING

8-9
08
If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the shift lever in P (Park, for
automatic transmission/dual clutch
transmission vehicle) or neutral (for
manual transmission/dual clutch
transmission vehicle) and set the
parking brake. If the air conditioning is
ON, turn it OFF.
3. If engine coolant is running out under
the vehicle or steam is coming out
from the bonnet, stop the engine. Do
not open the bonnet until the coolant
has stopped running or the steaming
has stopped. If there is no visible
loss of engine coolant and no steam,
leave the engine running and check
to be sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.
WARNING
Whilst the engine is
running, keep hands,
clothing and tools away
from the moving parts such
as the cooling fan and drive
belt to prevent serious
injury.4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out, stop
the engine immediately and we
recommend that you call a HYUNDAI
authorised repairer for assistance.
WARNING
NEVER remove the radiator
cap or the drain plug whilst
the engine and radiator are
hot. Hot coolant and steam
may blow out under
pressure, causing serious injury.
Turn the engine off and wait until the
engine cools down. Use extreme care
when removing the radiator cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back whilst 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.
