Maintenance
CAUTION
• Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tyre pres-
sures at the proper levels. If a
tyre frequently needs refilling,
have it checked by an autho-
rised HYUNDAI dealer.
• Overinflation produces
harsh ride, excessive wear at
the centre of the tyre tread,
and a greater possibility of
damage from road hazards.

CAUTION
• Warm tyres normally exceed
recommended cold tyre pres-
sures by 28 to 41 kPa (4 to 6
psi). Do not release air from
warm tyres to adjust the pres-
sure or the tyres will be under-
inflated.
• Be sure to reinstall the tyre
inflation valve caps. Without
a the valve cap, dirt or moisture
could get into the valve core
and cause air leakage. If a
valve cap is missing, install a
new one as soon as possible.
WARNING - Tyre inflation
Overinflation or underinflation
can reduce tyre life, adversely
affect vehicle handling, and
lead to sudden tyre failure. This
could result in loss of vehicle
control and potential injury.
CAUTION - Tyre pressure
Always observe the following:
• Check tyre pressure when the
tyres are cold. (After vehicle
has been parked for at least
three hours or hasn't been
driven more than 1.6 km (one
mile) since startup.)
• Check the pressure of your
spare tyre each time you
check the pressure of other
tyres.
• Never overload your vehicle.
Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
• Worn, old tyres can cause
accidents. If your tread is
badly worn, or if your tyres
have been damaged, replace
them.
