2018 Hyundai Ioniq Hybrid tow

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.

Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transmission fluid, axle lubri-
cant and cooling system fluid. Brake
condition is another important item to
frequently check. If you’re trailering,
it’s a good idea to review these items
before you start your trip. Don’t forget
to also maintain your trailer and
hitch. Follow the maintenance sched-
ule that accompanied your trailer and
check it periodically. Preferably, con-
duct the check at the start of each
day’s driving. Most importantly, all
hitch nuts and bolts should be tight.To prevent vehicle damage:
• Due to higher load during trailer
usage, overheating might occur
on hot days or during uphill driv-
ing. If the coolant gauge indi-
cates over-heating, switch off
the air conditioner and stop the
vehicle in a safe area to cool
down the engine.
• Do not switch off the engine
while the coolant gauge indi-
cates over-heating.
(Keep the engine idle to cool
down the engine)
• When towing check automatic
transmission fluid more fre-
quently.
• If your vehicle is not equipped
with an air conditioner, you
should install a condenser fan
to improve engine performance
when towing a trailer.

Batteries contain sulfu-
ric 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 imme-
diate medical attention. If acid
gets on your skin, thoroughly
wash the area. If you feel pain or
a burning sensation, get med-
ical 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.

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.

7. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
8. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call an
authorized HYUNDAI dealer for
assistance.
•Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked by an
authorized HYUNDAI dealer.
•When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
CAUTION
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 pres-
sure, causing serious injury.
Turn the hybrid system off and
wait until the engine cools down.
Use extreme care when remov-
ing 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.
WARNING

The TPMS Malfunction Indicator
may illuminate after blinking for
one minute if the vehicle is near
electric power supply cables or
radio transmitters such as police
stations, government and public
offices, broadcasting stations,
military installations, airports,
transmitting towers, etc.
Additionally, the TPMS Malfunction
Indicator may illuminate if snow
chains are used or electronic
devices such as computers, charg-
ers, remote starters, navigation,
etc. This may interfere with normal
operation of the TPMS.
Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure and Position telltales will
come on. Have the flat tire repaired
by an authorized HYUNDAI dealer
as soon as possible or replace the
flat tire with the spare tire.
The spare tire (if equipped) does not
come with a tire pressure monitoring
sensor. When the low pressure tire or
the flat tire is replaced with the spare
tire, the Low Tire Pressure Telltale will
remain on. Also, the TPMS Malfunction
Indicator will illuminate after blinking for
one minute if the vehicle is driven at
speed above 25 km/h (15.5 mph) for
approximately 10 minutes.Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pres-
sure and reinstalled on the vehicle,
the Low Tire Pressure Telltale and
TPMS Malfunction Indicator will go
off within a few minutes of driving.
If the indicators do not extinguish
after a few minutes, please visit an
authorized HYUNDAI dealer.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem (except for
the spare tire). You must use TPMS
specific wheels. It is recommended
that you always have your tires serv-
iced by an authorized HYUNDAI
dealer.
You may not be able to identify a tire
with low pressure by simply looking
at it. Always use a good quality tire
pressure gauge to measure. Please
note that a tire that is hot (from being
driven) will have a higher pressure
measurement than a tire that is cold.
NOTICE
What to do in an emergency
Never use a puncture-repairing
agent not approved by HYUNDAI
dealer to repair and/or inflate a
low pressure tire. Tire sealant
not approved by HYUNDAI deal-
er may damage the tire pressure
sensor.
