Reverse Parking Collision-Avoidance
Assist may unnecessarily warn the driver
or assist with braking even if there are
no pedestrians or objects under the
following circumstances:
• Any non-factory equipment or
accessory is installed
• Your vehicle is unstable due to an
accident or other causes
• Bumper height or rear ultrasonic
sensor installation has been modified
• Your vehicle height is low or high
due to heavy loads, abnormal tire
pressure, etc.
• Rear view camera or the rear
ultrasonic sensor(s) is stained with
foreign material, such as snow, dirt,
etc.
• The pattern on the road is mistaken
for a pedestrian
• There is shadow or light reflecting on
the ground
• Pedestrians or objects are around the
path of the vehicle
• Objects generating excessive
noise, such as vehicle horns, loud
motorcycle engines or truck air
brakes, are near your vehicle
• Your vehicle is backing towards a
narrow passage or parking space
• Your vehicle is backing towards an
uneven road surface, such as an
unpaved road, gravel, bump, gradient,
etc.
• A trailer or carrier is installed on the
rear of your vehicle
• An ultrasonic sensor with similar
frequency is near your vehicle WARNING
Take the following precautions when
using Reverse Parking Collision-
Avoidance Assist:
• Always pay extreme caution while
driving. The driver is responsible for
controlling the brake for safe driving.
• Always pay attention to road and
traffic conditions while driving,
whether or not there is a warning.
• Always look around your vehicle to
make sure there are no pedestrians
or objects before moving the vehicle.
• The performance of Reverse Parking
Collision-Avoidance Assist may
vary under certain conditions. If
vehicle speed is above 2 mph (4
km/h), Reverse Parking Collision-
Avoidance Assist will provide
collision avoidance assist only when
pedestrians are detected. Always
look around and pay attention when
backing up your vehicle.
• Some objects may not be detected
by the rear ultrasonic sensors due
to the objects distance, size or
material, all of which can limit the
effectiveness of the sensor.
• Reverse Parking Collision-Avoidance
Assist may not operate properly
or may operate unnecessarily
depending on the road conditions
and the surroundings.
• Do not solely rely on Reverse Parking
Collision-Avoidance Assist. Doing
so may lead to vehicle damage or
injuries.

If you have a flat tire while
driving
If a tire goes flat while you are driving:
• Take your foot off the accelerator
pedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately or
attempt to pull off the road as this
may cause loss of vehicle control
resulting in an accident. When the
vehicle has slowed to such a speed
that it is safe to do so, brake carefully
and pull off the road. Drive off the
road as far as possible and park on
firm, level ground. If you are on a
divided highway, do not park in the
median area between the two traffic
lanes.
• When the vehicle is stopped, press the
hazard warning flasher button, shift
the gear to P (Park), apply the parking
brake, and press the Engine Start/Stop
button to the OFF position.
• Have all passengers get out of the
vehicle. Be sure they all get out on the
side of the vehicle that is away from
traffic.
• When changing a flat tire, follow the
instructions provided later in this
chapter.
IF THE ENGINE WILL NOT
S TA RT
• Be sure to shift the gear to N (Neutral)
or P (Park). The engine starts only
when the gear is in N (Neutral) or P
(Park).
• Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
See instructions for “Jump Starting”
provided in this chapter.
• Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, we
recommend that you call an authorized
HYUNDAI dealer for assistance.
NOTICE
Push or pull starting the vehicle may
cause the catalytic converter to
overload which can lead to damage to
the emission control system.

A vehicle can slip or roll off of a jack
causing serious injury or death to you or
those nearby. Take the following safety
precautions:
• Do not get under a vehicle that is
supported by a jack.
• NEVER attempt to change a tire in
the lane of traffic. ALWAYS move the
vehicle completely off the road on
level, firm ground away from traffic
before trying to change a tire. If you
cannot find a level, firm place off
the road, call a towing service for
assistance.
• Be sure to use the jack provided with
the vehicle.
• ALWAYS place the jack on the
designated jacking positions on the
vehicle and NEVER on the bumpers
or any other part of the vehicle for
jacking support.
• Do not start or run the engine while
the vehicle is on the jack.
• Do not allow anyone to remain in the
vehicle while it is on the jack.
• Keep children away from the road
and the vehicle. Follow these steps to change your
vehicle’s tire:
1. Park on a level, firm surface.
2. Shift the gear to P (Park), apply the
parking brake, and press the Engine
Start/Stop button to the OFF position.
3. Press the hazard warning flasher
button.
4. Remove the wheel lug wrench, jack,
jack handle, and spare tire from the
vehicle.
