Driving your vehicle
6-58
Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. When there is the risk that your
parking brake may freeze, temporarily
apply it with the gear in P (Park). Also,
block the rear wheels in advance, so the
vehicle may not roll. Then, release the
parking brake.
Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in such conditions during the severe
winter, you should check underneath
the vehicle on a regular basis, to ensure
that the front wheels and the steering
components is unblocked.
Carry emergency equipment
In accordance with weather conditions,
you should carry appropriate emergency
equipment, while driving. Some of the
items you may want to carry include tire
chains, tow straps or chains, flashlight,
emergency flares, sand, shovel, jumper
cables, window scraper, gloves, ground
cloth, coveralls, blanket, etc.
Do not place objects or materials in the
engine compartment
Putting objects or materials in the engine
compartment may cause an engine
failure or combustion, because they may
block the engine cooling. Such damage
will not be covered by the manufacturer’s
warranty.

Backing up
Hold the bottom of the steering wheel
with one hand. Then, to move the trailer
to the left, move your hand to the left. To
move the trailer to the right, move your
hand to the right. Always back up slowly
and, if possible, have someone guide
you.
Making turns
When you’re turning with a trailer, make
wider turns than normal. Do this so your
trailer won’t strike soft shoulders, curbs,
road signs, trees, or other objects. Avoid
jerky or sudden maneuvers. Signal well in
advance.
Turn signals
When you tow a trailer, your vehicle has
to have a different turn signal flasher and
extra wiring. The green arrows on your
instrument panel will flash whenever you
signal a turn or lane change. Properly
connected, the trailer lights will also flash
to alert other drivers you’re about to turn,
change lanes, or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer
are burned out. Thus, you may think
drivers behind you are seeing your
signals when, in fact, they are not. It’s
important to check occasionally to be
sure the trailer bulbs are still working.
You must also check the lights every time
you disconnect and then reconnect the
wires.
WARNING
Do not connect a trailer lighting system
directly to your vehicle’s lighting
system. Use an approved trailer wiring
harness. Failure to do so could result in
damage to the vehicle electrical system
and/or personal injury. We recommend
that you consult an authorized
HYUNDAI dealer for assistance.
Driving on hills
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get overheated and may
not operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 45 mph (70
km/h) to reduce the possibility of engine
and transmission overheating.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes and you have a automatic
transmission, you should drive in D
(Drive) when towing a trailer.
Operating your vehicle in D (Drive)
when towing a trailer will minimize heat
build-up and extend the life of your
transmission.

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.
ONX4080003
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.
