Driving the vehicle after it has been
parked on a hill
1. With the gear in P (Park), apply your
brakes and hold the brake pedal down
while you:
• Start your engine;
• Shift into gear; and
• Release the parking brake.
2.
Slowly r

emove your foot from the
brake pedal.
3.
Drive slo

wly until the trailer is clear of

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,
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 hitch.
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 hitch nuts and bolts
should be tight.
NOTICE
To prevent vehicle damage:
• 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.
• Do not switch off the engine while
the coolant gauge indicates over-
heating.
(Keep the engine idle to cool down
the engine)
• When towing check transmission
fluid more frequently.
• 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 Reverse Parking
Distance Warning can be affected
by several factors (including
environmental conditions). It is the
responsibility of the driver to always
check the rear view before and while
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

Driver assistance system
7-146
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.
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.
• Reverse Parking Collision-Avoidance
Assist 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.

Emergency situations

NOTICE
External power source using 12V battery
The use of external power accessories
may reduce performance and function
of the vehicle. Especially, the use of
dash cameras may shut off the power of
the vehicle prior to the dash camera’s
automatic shut-down.
If the power of the vehicle is shut off,
start the vehicle as explained. (refer to
“Using the 12V Battery Reset Switch”)
Jump Starting
In the event vehicle still does not have a
functional 12V battery (check if interior
lights will not turn on) then you can try
a jump start to the engine compartment
jumper terminals using a 12V booster
pack or jumper cables from another
vehicle’s 12V battery according to the
following instructions.
CAUTION
Jump starting can be dangerous if
done incorrectly. Follow the jump
starting procedure in this section to
avoid serious injury or damage to
your vehicle. If in doubt about how to
properly jump start your vehicle, we
strongly recommend that you have a
service technician or towing service do
it for you.
1.
Position the v
ehicles close enough
that the jumper cables will reach, but
do not allow the vehicles to touch.
Avoid fans or any moving parts in the
engine compartment at all times, even
when the vehicles are turned off.
2.
Turn o

ff all electrical devices such as
radios, lights, air conditioning, etc.
Put the vehicles in P (Park) and set the
parking brake. Turn both vehicles OFF.

3. Connect the jumper cables in
the ex act sequence shown in the
illustration. First connect one jumper
cable to the red, positive (+) jumper
terminal of your vehicle (1).
4.
Connect the other end o

f the jumper
cable to the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
5.
Connect the second jumper cable to
the black, nega

tive (-) battery/chassis
ground of the assisting vehicle (3).
6.
Connect the other end o

f the second
jumper cable to the black, negative (-)
chassis ground of your vehicle (4).
Do not allow the jumper cables to
contact anything except the correct
battery or jumper terminals or the
correct ground. Do not lean over the
battery when making connections.

Emergency situations8-8
if tHe engine overHea ts
If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1.
Pull off the r

oad and stop as soon as it
is safe to do so.
2.
Shift the gear to P (P

ark) and set the
parking brake
3.
Turn o

ff the air conditioner.
4.
When the coolant or ho

t steams
gush out of the reservoir, stop the
engine and we recommend that
you call an authorized HYUNDAI
dealer for assistance. If the coolant
does not flow out, leave the engine
compartment opened, while running
the engine. Check the coolant
temperature gauge on the instrument
cluster and turn off the engine to
make sure the coolant temperature is
sufficiently cooled down. 5. Cool down the engine sufficien
tly
and check the coolant level. When it
is insufficient, check its connection
with the radiator, the heater hose,
and the water pump for any leakage.
When there is no leakage, add the
coolant. However, if the problems
persists, such as the coolant leakages,
the cooling-fan malfunction or the
water pump drive belt damages,
immediately stop the engine, and
have your vehicle checked by an
authorized HYUNDAI dealer.
• You should mix antifreeze and water in
a proper ratio to make coolant. If the
antifreeze ratio is too high or low, it
may cause overheating due to the lack
of cooling function.
(Refer to the Mix Ratio in “Checking
the coolant level” in chapter 8.)
• If overheating happens repeatedly,
we recommend that you have
your vehicle to be checked by an
authorized HYUNDAI dealer.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury.
