Driving your vehicle
Ready to leave after parking on a
hill
1. With the shift lever to P (Park, for
Automatic transmission/Dual clutch
transmission vehicle) or neutral (for
Manual transmission vehicle), apply
your brakes and hold the brake pedal
down whilst you:

V Start your engine;

V Shift into gear; and

V Release the parking brake.
2. Slowly remove your foot from the
brake pedal.
3. Drive slowly until the trailer is clear of
the chocks.
4. Stop and have someone pick up and
store the chocks.
Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include engine oil,
automatic transmission/dual clutch
transmission fluid, axle lubricant and
cooling system fluid. Brake condition
is another important item to frequently
check. If you’re trailering, it’s a good
idea to review these items before
you start your trip. Don’t forget to
also maintain your trailer and towbar.
Follow the maintenance schedule that
accompanied your trailer and check it
periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all towbar nuts and
bolts should be tight.
NOTICE
To prevent vehicle damage:

V Due to higher load during trailer
usage, overheating might occur on
hot days or during uphill driving. If
the coolant gauge indicates over-
heating, switch off the air conditioner
and stop the vehicle in a safe area to
cool down the engine.

V When towing check Automatic
transmission/Dual clutch
transmission fluid more frequently.

V If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.

WARNING

[Reverse Parking Distance Warning
is a supplemental function. The
operation of the function can be
affected by several factors (including
environmental conditions). It is the
responsibility of the driver to always
check the rear view before and whilst
parking.

[Your new vehicle warranty does not
cover any accidents or damage to
the vehicle due to the malfunction of
Reverse Parking Distance Warning.

[Pay close attention when driving near
objects, pedestrians, and especially
children. Some objects may not be
detected by the ultrasonic sensors,
due to the objects distance, size or
material, all of which can limit the
effectiveness of the sensor.
Limitations of Reverse Parking
Distance Warning

[Reverse Parking Distance Warning
may not operate normally when:
- Moisture is fTrozen to the sensor
- Sensor is covered with foreign
material, such as snow or water (The
function will operate normally when
such foreign material are removed.)
- The weather is extremely hot or cold
- The sensor or sensor assembly is
disassembled
- The surface of the sensor is pressed
hard or an impact is applied with a
hard object
- The surface of the sensor is
scratched with a sharp object
- The sensors or its surrounding area is
directly sprayed with high pressure
washer
[Reverse Parking Distance Warning
may malfunction when:
- Heavy rain or water spray is present
- Water flows on the surface of the
sensor
 $IIHFWHGE\DQRWKHUYHKLFOH
TVVHQVRUV
- The sensor is covered with snow
- Driving on uneven road, gravel roads
or bushes
- Objects that generates ultrasonic
waves are near the sensor
- Installing the license plate differently
from the original location
- The vehicle bumper height or
ultrasonic sensor installation has
been modified
- Attaching equipments or accessories
around the ultrasonic sensors

[The following objects may not be
detected:
- Sharp or slim objects, such as ropes,
chains or small poles.
- Objects, which tend to absorb sensor
frequency, such as clothes, spongy
material or snow.
- Objects smaller than 100 cm (40 in.)
in length and narrower than 14 cm (6
in.) in diameter.
- Pedestrians, animals or objects
that are very close to the ultrasonic
sensors

[ Parking Distance Warning Indicators
may be displayed differently from
the actual detected location when
the obstacle is located between the
sensors.

[Parking Distance Warning indicator
may not occur sequentially depending
on vehicle speed or obstacle shape.

[If Reverse Parking Distance Warning
needs repair, we recommend that the
function be inspected by a HYUNDAI
authorised repairer.

WARNING
Take the following precautions when
using Reverse Parking Collision-
Avoidance Assist:

[Always pay extreme caution whilst
driving. The driver is responsible for
controlling the brake for safe driving.

[Always pay attention to road and
traffic conditions whilst 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
the vehicle speed is above 2 mph
(4 km/h), the function 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 the function.
Doing so may lead to vehicle damage
or injuries.
CAUTION

[Noise may be heard when sudden
braking occurs to avoid a collision.

[If any other warning sound such
as the seat belt warning chime is
already generated, Reverse Parking
Collision-Avoidance Assist warning
may not sound.

[The function may not work properly
if the bumper has been damaged,
replaced or repaired.

[Reverse Parking Collision-Avoidance
Assist may not operate normally if
interfered by strong electromagnetic
waves.

[Playing the vehicle audio system at
high volume may prevent passengers
from hearing Reverse Parking
Collision-Avoidance Assist warning
sounds.

[Turn off Reverse Parking Collision-
Avoidance Assist when towing a
trailer. If towing and moving in
reverse, Reverse Parking Collision-
Avoidance Assist will activate as it
detects the trailer.
