2017 Hyundai Sonata Plug-in Hybrid engine

6-8
What to do in an emergency7. If you cannot find the cause of theoverheating, 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,
call an authorized HYUNDAI deal-
er for assistance.
Serious loss of coolant indi-
cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
WARNING
Your vehicle is
equipped with a pres-
surized coolant
reserve tank. NEVER
remove the coolant
reserve tank cap or the radiator
drain plug while 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 remov-
ing the coolant reserve tank
cap. Wrap a towel or thick rag
around it, and turn it counter-
clockwise slowly to release
some of the pressure from the
system. Step back while the
pressure is released.
When you are sure all the pres-
sure has been released, contin-
ue turning the cap counter-
clockwise to remove it.

Check tire pressure
You can check the tire pressure inthe Information Mode on the clus-
ter.
Refer to the "User Settings
Mode" section in chapter 3.
Tire pressure is displayed after a few minutes of driving after initial
engine start up.
If tire pressure is not displayed when the vehicle is stopped, "Drive
to display" message will appear.
After driving, check the tire pres-
sure. The displayed tire pressure values
may differ from those measured
with a tire pressure gauge.
You can change the tire pressure unit in the User Settings Mode on
the cluster.

Settings Mode" section in
chapter 3).

Always check the TPMS malfunction
LCD display after replacing one or
more tires or wheels on your vehicle
to ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function proper-
ly.
If any of the below happens, have
the system checked by an author-
ized HYUNDAI dealer.
1. The Low Tire Pressure TPMSMalfunction Indicator does not
illuminate for 3 seconds when
the ignition switch is placed to
the ON position or engine is
running.
2. The TPMS Malfunction Indicator remains illuminated after blink-
ing for approximately 1 minute.
3. The Low Tire Pressure LCD dis- play remains illuminatedLow tire pressure
indicator
Low tire pressure
LCD display with
position indicator
When the tire pressure monitoring
system warning indicators are illumi-
nated and the warning message is
displayed on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The LCD posi-
tion indicator will indicate which tire
is significantly under-inflated by illu-
minating the corresponding position
light. If any of your tire pressures are indi-
cated as being low, immediately
reduce your speed, avoid hard cor-
nering, and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle’s placard or tire inflation pressure
label located on the driver’s side cen-
ter pillar outer panel.
If you cannot reach a service station
or if the tire cannot hold the newly
added air, replace the low pressure
tire with the spare tire.
The Low Tire Pressure LCD position
indicator will remain on and the
TPMS Malfunction Indicator may
blink for one minute and then remain
illuminated until you have the low
pressure tire repaired and replaced
on the vehicle.
The spare tire is not equipped with
a tire pressure sensor.

It is possible that some tires, espe-
cially with larger punctures or dam-
age to the sidewall, cannot be sealed
completely.
Air pressure loss in the tire may
adversely affect tire performance.
For this reason, you should avoid
abrupt steering or other driving
maneuvers, especially if the vehicle
is heavily loaded or if a trailer is in
use.
The Tire Mobility Kit is not designed
or intended as a permanent tire
repair method and is to be used for
one tire only.
This instruction shows you step by
step how to temporarily seal the
puncture simply and reliably.
Read the section "Notes on the safe
use of the Tire Mobility Kit".Notes on the safe use of theTire Mobility Kit
Park your car at the side of the
road so that you can work with the
Tire Mobility Kit away from moving
traffic.
To be sure your vehicle will not move, even when you're on fairly
level ground, always set your park-
ing brake.
Only use the Tire Mobility Kit for sealing/inflation passenger car
tires. Only punctured areas located
within the tread region of the tire
can be sealed using the tire mobil-
ity kit.
Do not use on motorcycles, bicy- cles or any other type of tires.
When the tire and wheel are dam- aged, do not use Tire Mobility Kit
for your safety.
Use of the Tire Mobility Kit may not be effective for tire damage larger
than approximately 0.24 inch (6
mm).
Please contact the nearest
HYUNDAI dealership if the tire
cannot be made roadworthy with
the Tire Mobility Kit. Do not use the Tire Mobility Kit if a
tire is severely damaged by driving
run flat or with insufficient air pres-
sure.
Do not remove any foreign objects such as nails or screws that have
penetrated the tire.
Provided the car is outdoors, leave the engine running. Otherwise
operating the compressor may
eventually drain the car battery.
Never leave the Tire Mobility Kit unattended while it is being used.
Do not leave the compressor run- ning for more than 10 minutes at a
time or it may overheat.
Do not use the Tire Mobility Kit if the ambient temperature is below
-22°F (-30°C).

When towing your vehicle in an
emergency without wheel dollies :
1. Place the Engine Start/Stop but-ton in the ACC position.
2. Place the shift lever in N (Neutral).
3. Release the parking brake.Removable towing hook
1. Open the trunk, and take the tow- ing hooks out from the tool case. 2. Open the cover by pressing the
lower part on the front bumper.
3. Install the towing hook by rotating it in a clock-wise direction until it is
securely installed.
4. After use, remove the towing hook and close the cover.
Failure to place the transmis-
sion shift lever in N (Neutral)
may cause internal damage to
the transmission.

What to do in an emergency
Emergency Towing
(if equipped)
If towing is necessary, we recom-
mend you to have it done by an
authorized HYUNDAI dealer or a
commercial tow truck service.If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook at the rear of the vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. A
driver must be in the vehicle to steer
it and operate the brakes.
Towing should be done only on a
solid ground for a short distance and
at a low speed.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
Always follow these emergency tow-
ing precautions:
Place the Engine Start/Stop button
in the ACC position so the steering
wheel is not locked.
Place the shift lever in N (Neutral).
Release the parking brake.
Depress the brake pedal with more force than normal since you will
have reduced braking perform-
ance.
More steering effort will be required because the power steer-
ing system will be disabled.
Use a vehicle heavier than your own to tow your vehicle.
The drivers of both vehicles should communicate with each other fre-
quently.
Before emergency towing, check that the hook is not broken or dam-
aged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply steady and even force.
