C310D01NF-AATIndicators and WarningThe indicators should illuminate when the
ignition key is turned to ON or START but
should go out after three seconds.
If the indicators do not illuminate, or the
ESC or ESC-OFF indicator does not go out
after 3 seconds, have the vehicle checked
by an authorized dealer.
Should there be any unusual operation of
the device while driving, the ESC-OFF
indicator illuminates as a warning.
If the ESC-OFF indicator illuminates, drive
your car to a safe place and stop the
engine.
Then, start the engine again to check if the
ESC-OFF indicator goes out.
If the indicator remains lit even after the
engine has been started, have your car
checked by an authorized Hyundai dealer.
C310B01NF-AATESC ON/OFF ModeWhen the ESC is operating, the ESC indi-
cator in the instrument cluster will blink.
If you turn the system off by pressing the
ESC switch, the ESC-OFF indicator will
come on and stay on. In the ESC-OFF
mode, the stability control will be
deactivated. Adjust your driving accord-
ingly. To turn the system back on, press the
switch again. The ESC-OFF indicator
should go off.NOTE:The ESC mode will automatically be
turned ON after the engine is turned off
and restarted.
CAUTION:
Driving with varying tire or wheel sizes
may cause the ESC system to
malfunction. When replacing tires, make
sure they are the same size as your
original tires.

SMOOTH CORNERINGC150A01A-AATAvoid braking or gear changing in corners,
especially when roads are wet. Ideally,
corners should always be taken under
gentle acceleration. If you follow these
suggestions, tire wear will be held to a
minimum.
C160A01A-AATThe more severe weather conditions of
winter result in greater wear and other
problems. To minimize the problems of
winter driving, you should follow these
suggestions:C160B01A-AATSnowy or Icy ConditionsTo drive your vehicle in deep snow, it may
be necessary to use snow tires or to install
tire chains on your tires. If snow tires are
needed, it is necessary to select tires
equivalent in size and type of the original
equipment tires. Failure to do so may
adversely affect the safety and handling of
your car. Furthermore, speeding, rapid
acceleration, sudden brake applications,
and sharp turns are potentially very
hazardous practices.
During deceleration, use engine braking to
the fullest extent. Sudden brake applications
on snowy or icy roads may cause skids to
occur. You need to keep sufficient distance
between the vehicle in operation in front
and your vehicle. Also, apply the brake
gently. It should be noted that installing tire
chains on the tire will provide a greater
driving force, but will not prevent side skids.NOTE:Tire chains are not legal in all states.
Check state laws before fitting tire
chains.WINTER DRIVING
C160D01A-AATCheck Battery and CablesWinter puts additional burdens on the
battery system. Visually inspect the battery
and cables as described in Section 6. The
level of charge in your battery can be
checked by your Hyundai dealer or a
service station.C160C01A-AATUse High Quality Ethylene Glycol
CoolantYour Hyundai is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubricates
the water pump and prevents freezing. Be
sure to replace or replenish your coolant in
accordance with the maintenance
schedule in Section 5. Before winter, have
your coolant tested to assure that its
freezing point is sufficient for the
temperatures anticipated during the winter.
