DRIVING YOUR HYUNDAI
17
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.
