Low Tire Pressure
Warning Light
(if equipped)
This warning light illuminates:
• Once you turn the ignition switch or
Engine Start/Stop button to the ON
position.
- It illuminates for approximately 3
seconds and then goes off.
• When one or more of your tires are
significantly underinflated (The
location of the underinflated tire is
displayed on the supervision clus-
ter LCD display).
For more details, refer to
“Tire Pressure Monitoring System
(TPMS)” in chapter 6.
This warning light remains ON
after blinking for approximately 60
seconds, or repeatedly blinks ON
and OFF in 3 second intervals:
• When there is a malfunction with
the TPMS.
In this case, we recommend that
you have the vehicle inspected by
an authorized HYUNDAI dealer as
soon as possible.
For more details, refer to
“Tire Pressure Monitoring System
(TPMS)” in chapter 6.
Fuel Filter Warning
Light (for diesel engine)
This warning light illuminates:
• When water has accumulated
inside the fuel filter.
In this case, remove the water from
the fuel filter.
For more details, refer to “Fuel
Filter” in chapter 7.
• When the Fuel Filter Warning
Light illuminates, engine power
(vehicle speed & idle speed) may
decrease.
• If you keep driving with the warn-
ing light on, engine parts (injec-
tor, common rail, high pressure
fuel pump) may be damaged. If
this occurs, we recommend that
you have the vehicle inspected
by an authorized HYUNDAI deal-
er as soon as possible.

Driving your vehicle
If you are considering to tow with
your vehicle, you should first check
with your country's Department of
Motor Vehicles to determine legal
requirements. Since laws vary the
requirements for towing trailers, cars,
or other types of vehicles or appara-
tus may differ. Ask an authorized
HYUNDAI dealer for further details
before towing.
Remember that trailering is different
than just driving your vehicle by itself.
Trailering means changes in han-
dling, durability, and fuel economy.
Successful, safe trailering requires
correct equipment, and it has to be
used properly. Damage to your vehi-
cle caused by improper trailer towing
is not covered by your vehicle manu-
facturer’s warranty.This section contains many time-
tested, important trailering tips and
safety rules. Many of these are
important for your safety and that of
your passengers. Please read this
section carefully before you pull a
trailer.
TRAILER TOWING
Take the following precautions:
•If you don't use the correct
towing equipment, or if you
drive improperly while towing,
you can lose control of the
vehicle when pulling a trailer.
For example, if the trailer is
too heavy, the braking per-
formance may be reduced.
You and your passengers
could be seriously or fatally
injured. Pull a trailer only if
you have followed all the
steps in this section.
•Before towing, make sure the
total trailer weight, GCW
(Gross Combination Weight),
GVW (Gross Vehicle Weight),
GAW (Gross Axle Weight ) and
trailer tongue load are all with-
in the limits.
WARNING

Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in the engine
coolant reservoir.
• Check the windshield washer fluid
level.
• Check for low or under-inflated
tires.
While operating your vehicle:
• Note any changes in the sound of
the exhaust or any smell of exhaust
fumes in the vehicle.
• Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
• Notice if your vehicle constantly
turns slightly or “pulls” to one side
when traveling on smooth, level
road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or
“hard-to-push” brake pedal.
• If any slipping or changes in the
operation of your transmission
occurs, check the transmission fluid
level.
• Check the automatic transmission
P (Park) function.
• Check the parking brake.
• Check for fluid leaks under your vehi-
cle (water dripping from the air con-
ditioning system during or after use
is normal).

Maintenance
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
WARNING
Diesel Engine
Never manipulate or modify the
injection system while running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
the high pressure right after
stopping the diesel engine.
When the fuel leakage vents out,
it may cause serious body injury.
Any people, who are implement-
ed with the artificial cardiac
pacemaker, should remain away
from the ECU or the wiring har-
ness by at least 30 cm, while run-
ning the diesel engine. The high
currents of the electric engine
control system produce a con-
siderable amount of magnetic
fields.
