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.

Low tyre pressure
warning light
Low tyre pressure position and
tyre pressure telltale
ONX4E040019
When the tyre pressure monitoring
system warning indicators are
illuminated and a warning message
displayed on the cluster LCD display,
one or more of your tyres is significantly
under-inflated. The Low Tyre Pressure
Position Telltale will indicate which
tyre is significantly underinflated by
illuminating the corresponding position
light.
If either telltale illuminates, immediately
reduce your speed, avoid hard cornering
and anticipate increased stopping
distances. You should stop and check
your tyres as soon as possible. Inflate the
tyres to the proper pressure as indicated
on the vehicle’s placard or tyre inflation
pressure label located on the driver’s
side centre pillar outer panel.If you cannot reach a service station or
if the tyre cannot hold the newly added
air, replace the low pressure tyre with
the spare tyre.
The Low Tyre Pressure Telltale will
remain on and the TPMS Malfunction
Indicator may blink for one minute
and then remain illuminated (when
the vehicle is driven approximately 10
minutes at speed above 15.5 mph (25
km/h)) until you have the low pressure
tyre repaired and replaced on the
vehicle.
CAUTION
In winter or cold weather, the Low Tyre
Pressure Telltale may be illuminated if
the tyre pressure was adjusted to the
recommended tyre inflation pressure
in warm weather. It does not mean
your TPMS is malfunctioning because
the decreased temperature leads to a
proportional lowering of tyre pressure.
When you drive your vehicle from a
warm area to a cold area or from a cold
area to a warm area, or the outside
temperature is greatly higher or lower,
you should check the tyre inflation
pressure and adjust the tyres to the
recommended tyre inflation pressure.
WARNING
Low pressure damage
Significantly low tyre pressure makes
the vehicle unstable and can contribute
to loss of vehicle control and increased
braking distances.
Continued driving on low pressure
tyres can cause the tyres to overheat
and fail.

8-15
08
If the indicators do not extinguish after
a few minutes, it is recommended to
contact the nearest authorised HYUNDAI
dealer.
Each wheel is equipped with a tyre
pressure sensor mounted inside the tyre
behind the valve stem (except for the
spare tyre). You must use TPMS specific
wheels. It is recommended that you
always have your tyres serviced by a
HYUNDAI authorised repairer.
You may not be able to identify a tyre
with low pressure by simply looking at it.
Always use a good quality tyre pressure
gauge to measure. Please note that a
tyre that is hot (from being driven) will
have a higher pressure measurement
than a tyre that is cold.
A cold tyre means the vehicle has been
sitting for 3 hours and driven for less
than 1 mile (1.6 km) in that 3 hour period.
Allow the tyre to cool before measuring
the inflation pressure. Always be sure
the tyre is cold before inflating to the
recommended pressure.
WARNING

[The TPMS cannot alert you to severe
and sudden tyre damage caused by
external factors such as nails or road
debris.

[If you feel any vehicle instability,
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 Tyre Pressure Monitoring System
(TPMS) components may interfere
with the system’s ability to warn the
driver of low tyre pressure conditions
and/or TPMS malfunctions. Tampering
with, modifying, or disabling the Tyre
Pressure Monitoring System (TPMS)
components may void the warranty for
that portion of the vehicle.
WARNING

[Do not modify the vehicle; it may
interfere with the TPMS function.

[The wheels on the market do not
have a TPMS sensor.

[For your safety, we recommend that
you use parts for replacement from a
HYUNDAI authorised repairer.

[If you use the wheels on the market,
use a TPMS sensor approved by a
HYUNDAI dealer or the equivalent
approved for your vehicle. If your
vehicle is not equipped with a TPMS
sensor or TPMS does not work
properly, you may fail the periodic
vehicle inspection conducted in your
country.

Changing tyres
WARNING
A vehicle can slip or roll off of a jack
causing serious injury or death to you
or those nearby. Take the following
safety precautions:

[Do not get under a vehicle that is
supported by a jack.

[NEVER attempt to change a tyre in
the lane of traffic. ALWAYS move the
vehicle completely off the road on
level, firm ground away from traffic
before trying to change a tyre. If you
cannot find a level, firm place off
the road, call a towing service for
assistance.

[Be sure to use the jack provided with
the vehicle.

[ALWAYS place the jack on the
designated jacking positions on the
vehicle and NEVER on the bumpers
or any other part of the vehicle for
jacking support.

[Do not start or run the engine whilst
the vehicle is on the jack.

[Do not allow anyone to remain in the
vehicle whilst it is on the jack.

[Keep children away from the road
and the vehicle.
Follow these steps to change your
vehicle’s tyre:
1. Park on a level, firm surface.
2. Move the shift lever into P (Park, for
automatic transmission/dual clutch
transmission vehicle) or neutral
(for manual transmission vehicle),
apply the parking brake, and place
the ignition switch in the LOCK/OFF
position.
3. Press the hazard warning flasher
button.
4. Remove the wheel lug nut wrench,
jack, jack handle, and spare tyre from
the vehicle.

If you have a tyre gauge, check the tyre
pressure (see “Tyres and Wheels” in
chapter 2 for tyre pressure instructions.).
If the pressure is lower or higher than
recommended, drive slowly to the
nearest service station and adjust it to
the recommended pressure. Always
reinstall the valve cap after checking
or adjusting tyre pressure. If the cap
is not replaced, air may leak from the
tyre. If you lose a valve cap, buy another
and install it as soon as possible. After
changing tyres, secure the flat tyre and
return the jack and tools to their proper
storage locations.

after driving over 50 km if tyres are
replaced. Re-check the tyre wheel
lug nuts after driving over 1,000 km.
CAUTION
Your vehicle has metric threads on
the studs and lug nuts. Make certain
during tyre changing that the same
nuts that were removed are reinstalled.
If you have to replace your lug nuts
make sure they have metric threads to
avoid damaging the studs and ensure
the wheel is properly secured to the
hub. We recommend that you consult
a HYUNDAI authorised repairer for
assistance.
If any of the equipment such as the jack,
lug nuts, studs, or other equipment is
damaged or in poor condition, do not
attempt to change the tyre and call for
assistance.
Use of compact spare tyres
(if equipped)
Compact spare tyres are designed for
emergency use only. Drive carefully
