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.• Smart Cruise Control system may
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.
NOTICE
Smart Cruise Control system may not
operate temporarily due to: • Electrical interference

pressure

Towing Service
ODN8079010L
[A] : Dollies
If emergency towing is necessary,
we recommend having it done by
an authorized HYUNDAI dealer or a
commercial tow-truck service. Proper
lifting and towing procedures are
necessary to prevent damage to the
vehicle. The use of wheel dollies or
flatbed is recommended.
On 2WD vehicles, it is acceptable to
tow the vehicle with the rear wheels
on the ground (without dollies) and
the front wheels off the ground. If any
of the loaded wheels or suspension
components are damaged or the vehicle
is being towed with the front wheels on
the ground, use a towing dolly under the
front wheels.
When being towed by a commercial tow
truck and wheel dollies are not used,
the front of the vehicle should always be
lifted, not the rear.
CAUTION
• Do not tow the vehicle with the front
wheels on the ground as this may
cause damage to the vehicle.
ODN8079012L
• Do not tow with sling-type
equipment. Use a wheel lift or
flatbed equipment.
