WARNING
When using Smart Cruise Control take
the following precautions:
• If an emergency stop is necessary,
you must apply the brakes. The
vehicle cannot be stopped at every
emergency situation by using Smart
Cruise Control system.
• Keep a safe distance according to
road conditions and vehicle speed. If
the vehicle to vehicle distance is too
close during a high-speed driving, a
serious collision may result.
• Always maintain sufficient braking
distance and decelerate your vehicle
by applying the brakes if necessary.
• Smart Cruise Control system cannot
recognize a stopped vehicle,
pedestrians or an oncoming vehicle.
Always look ahead cautiously to
prevent unexpected and sudden
situations from occurring.
• Vehicles moving in front of you with
a frequent lane change may cause
a delay in the system's reaction or
may cause the system to react to a
vehicle actually in an adjacent lane.
Always drive cautiously to prevent
unexpected and sudden situations
from occurring.
• Always be aware of the selected
speed and vehicle to vehicle
distance. The driver should not solely
rely on the system but always pay
attention to driving conditions and
control your vehicle speed.
• Smart Cruise Control system may not
recognize complex driving situations
so always pay attention to driving
conditions and control your vehicle
speed.

recognize a pedestrian, bicycle,
motorcycle, etc. as a vehicle. Always,
look ahead cautiously to prevent
unexpected and sudden situations
from occurring.
• Turn off Smart Cruise Control system
when the vehicle is being towed.

The severe weather conditions of winter
quickly wear out tires and cause other
problems. To minimize winter driving
problems, you should take the following
suggestions:
Snow or Icy Conditions
You need to keep sufficient distance
between your vehicle and the vehicle in
front of you.
Apply the brakes gently. 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 the
vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires or to
install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to carry
include tire chains, tow straps or chains,
a flashlight, emergency flares, sand, a
shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket,
etc.
Snow tires
WARNING
Snow tires should be equivalent in size
and type to the vehicle’s standard tires.
Otherwise, the safety and handling of
your vehicle may be adversely affected.
If you mount snow tires on your vehicle,
make sure to use radial tires of the same
size and load range as the original tires.
Mount snow tires on all four wheels
to balance your vehicle’s handling in
all weather conditions. The traction
provided by snow tires on dry roads
may not be as high as your vehicle's
original equipment tires. Check with
the tire dealer for maximum speed
recommendations.
Information
Do not install studded tires without
first checking local, state and municipal
regulations for possible restrictions against
their use.
Tire chains
ODN8069077LODN8069077L
Since the sidewalls of radial tires are
thinner than other types of tires, they
may be damaged by mounting some
types of tire chains on them. Therefore
the use of snow tires is preferred over the
use of tire chains.
If the road and weather conditions
require the use of tire chains, be sure to
use tire chains that have been properly
selected for the size of tire on your
HYUNDAI vehicle.
Be sure to follow the guidelines and
installation instructions provided from
the tire chain manufacturer.
Damage to your vehicle caused by
improper tire chain use is not covered by
your vehicle manufacturer’s warranty.
