Information
Make sure to refuel your vehicle
according to the "Fuel Requirements"
suggested in the Introduction chapter.
Do not spill fuel on the exterior surfaces of the vehicle. Any type of fuel spilled on painted sur-
faces may damage the paint.
If the fuel filler cap requires replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. Anincorrect fuel filler cap canresult in a serious malfunctionof the fuel system or emission
control system.Emergency fuel filler door

(Continued)
If a fire breaks out during refu-
eling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the gasstation and then contact the
local fire department. Follow
any safety instructions they
provide.
If pressurized fuel sprays out,
it can cover your clothes or
skin and thus subject you to
the risk of fire and burns.
Always remove the fuel cap
carefully and slowly. If the cap
is venting fuel or if you hear a
hissing sound, wait until the
condition stops before com-
pletely removing the cap.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the eventof an accident.

Emergency fuel filler doorrelease
If the fuel filler door does not open using the remote fuel filler door
release button, you can open it man-
ually. Pull the handle of the releaselocated on the left side of the lug-
gage compartment outward slightly.
In this case, slowly open the fuel tank
cap, because the fuel tank may be
highly pressurized. If fuel leaks out,
or if air hisses out, wait until it disap-
pears, open the fuel tank cap, and
slowly refuel the vehicle. If you quick-ly pour fuel into the fuel tank, the fuel
may overflow out of the fuel tank.

Maintenance
Check tire inflation pressure
Check your tires, including the spare
tire, once a month or more.
How to check
Use a good quality tire pressure
gauge to check tire pressure. You
can not tell if your tires are properly
inflated simply by looking at them.
Radial tires may look properly inflat-
ed when they are under-inflated.
Remove the valve cap from the tire
valve stem. Press the tire gauge firm-
ly onto the valve to get a pressure
measurement. If the cold tire inflationpressure matches the recommendedpressure on the tire and loading
information label, no further adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-
ommended pressure. Make sure to
put the valve caps back on the valve
stems. Without 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.If you overfill the tire, release air bypushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gauge. Be
sure to put the valve caps back on
the valve stems. Without 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.
Under-inflation results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation is also
possible. Keep your tire pres-
sures at the proper levels. If a
tire frequently needs refilling,
have it checked by an author-
ized HYUNDAI dealer.
Over-inflation produces a
harsh ride, excessive wear atthe center of the tire tread,and a greater possibility of
damage from road hazards.
