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.
A cold tire 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 tire to cool before measuring
the inflation pressure. Always be sure
the tire is cold before inflating to the
recommended pressure.
WARNING
• The TPMS cannot alert you to severe
and sudden tire 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 Tire Pressure Monitoring System
(TPMS) components may interfere
with the system’s ability to warn the
driver of low tire pressure conditions
and/or TPMS malfunctions. Tampering
with, modifying, or disabling the Tire
Pressure Monitoring System (TPMS)
components may void the warranty for
that portion of the vehicle.

13. Use the wheel lug nut wrench to
tighten the lug nuts in the order
shown. Double-check each lug nut
until they are tight. After changing
tires, have an authorized HYUNDAI
dealer tighten the lug nuts to their
proper torque as soon as possible. The
wheel lug nut should be tightened to
79~94 lbf·ft (11~13 kgf·m).
If you have a tire gauge, check the
tire pressure (see “Tires and Wheels”
section in chapter 1 for tire 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 tire pressure. If the cap
is not replaced, air may leak from the
tire. If you lose a valve cap, buy another
and install it as soon as possible. After
changing tires, secure the flat tire and
return the jack and tools to their proper
storage locations.
NOTICE
Check the tire pressure as soon as
possible after installing a spare tire.
Adjust it to the recommended pressure.
CAUTION
Your vehicle has metric threads on the
studs and lug nuts. Make certain during
tire 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.
Consult an authorized HYUNDAI dealer
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 tire and call for
assistance.
Use of compact spare tires
(if equipped)
Compact spare tires are designed for
emergency use only. Drive carefully on
the compact spare tire and always follow
the safety precautions.

Emergency situations
7-18
WARNING
To prevent compact spare tire failure
and loss of control possibly resulting in
an accident:
• Use the compact spare tire only in an
emergency.
• NEVER operate your vehicle over
50 mph (80 km/h).
• Do not exceed the vehicle’s
maximum load rating or the load
carrying capacity shown on the
sidewall of the compact spare tire.
• Do not use the compact spare tire
continuously. Repair or replace the
original tire as soon as possible to
avoid failure of the compact spare
tire.
When driving with the compact spare tire
mounted to your vehicle:
• Check the tire pressure after installing
the compact spare tire. The compact
spare tire should be inflated to 60 psi
(420 kPa).
• Do not take this vehicle through
an automatic car wash while the
compact spare tire is installed.
• Do not use the compact spare tire on
any other vehicle because this tire
has been designed especially for your
vehicle.
• The compact spare tire’s tread life is
shorter than a regular tire. Inspect
your compact spare tire regularly and
replace worn compact spare tires with
the same size and design, mounted on
the same wheel.
• Do not use more than one compact
spare tire at a time.
• Do not tow a trailer while the compact
spare tire is installed.
Information
When the original tire and wheel are
repaired and reinstalled on the vehicle,
the lug nut torque must be set correctly.
The correct lug nut tightening torque is
79~94 lbf·ft (11~13 kgf·m).
NOTICE
To prevent damaging the compact
spare tire and your vehicle:
• Drive slowly enough for the road
conditions to avoid all hazards, such
as a potholes or debris.
• Avoid driving over obstacles. The
compact spare tire diameter is
smaller than the diameter of a
conventional tire and reduces the
ground clearance approximately
1 inch (25 mm).
• Do not use tire chains on the
compact spare tire. Because of the
smaller size, a tire chain will not fit
properly.
• Do not use the compact spare tire
on any other wheels, nor should
standard tires, snow tires, wheel
covers or trim rings be used with the
compact spare wheel.

For safe operation, carefully read and
follow the instructions in this manual
before use.
(1) Compressor
(2) Sealant bottle
The Tire Mobility Kit is a temporary fix to
the tire and the tire should be inspected
by an authorized HYUNDAI dealer as
soon as possible.
CAUTION
When two or more tires are flat, do not
use the tire mobility kit because the
supported one sealant of Tire Mobility
Kit is only used for one flat tire.
WARNING
Do not use the Tire Mobility Kit to repair
punctures in the tire walls. This can
result in an accident due to tire failure.
WARNING
Have your tire repaired as soon as
possible. The tire may lose air pressure
at any time after inflating with the Tire
Mobility Kit.
Introduction
With the Tire Mobility Kit you stay mobile
even after experiencing a tire puncture.
The compressor and sealing compound
system effectively and comfortably seals
most punctures in a passenger car tire
caused by nails or similar objects and
reinflates the tire.
After you ensure that the tire is properly
sealed you can drive cautiously on the
tire (distance up to 120 miles (200 km))
at a max. speed of (50 mph (80 km/h))
in order to reach a service station or tire
dealer for the tire replacement.
It is possible that some tires, especially
with larger punctures or damage 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”.

insufficient air pressure.
Only punctured areas located within the
tread region of the tire can be sealed
using the TMK.
Notes on the Safe Use of the Tire
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 parking 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 mobility kit.
• Do not use on motorcycles, bicycles
or any other type of tires.
• When the tire and wheel are
