WARNING
If AWD warning light () stays on
the instrument cluster, your vehicle
may have a malfunction with the AWD
system. When the AWD warning light
(
) illuminates we recommend that
the vehicle be checked by an authorized
HYUNDAI dealer as soon as possible.
NOTICE
• Maintain AWD Auto mode when
driving on roads in normal
conditions.
• When driving under normal road
conditions (especially when
cornering) in AWD Lock mode, a
driver may find minor mechanical
vibration or noise, which is extremely
normal phenomenon, not a
malfunction. When AWD Lock mode
is released, such noise or vibration
will be immediately gone.
CAUTION
When driving on normal roads,
deactivate the AWD LOCK mode by
pushing the AWD LOCK button (AWD
LOCK indicator light goes off). Driving
on normal roads with the AWD LOCK
mode, especially, when cornering
may cause mechanical noise or
vibration. The noise and vibration will
disappear when the AWD LOCK mode
is deactivated. Prolong driving with the
noise and vibration may damage some
parts of the power train.
NOTICE
When the AWD LOCK mode is
deactivated, a sensation may be felt as
the driving power is delivered entirely
to the front wheels.
For safe AWD operation
Before driving
• Make sure all passengers are wearing
seat belts.
• Sit upright and closer to the steering
wheel than usual. Adjust the steering
wheel to a position comfortable for
you to drive.
Driving on snow-covered or icy roads
• Start off slowly by applying the
accelerator pedal gently.
• Use snow tires or tire chains.
• Keep sufficient distance between your
vehicle and the vehicle in front of you.
• Use engine braking during
deceleration.
• Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent skids.
Driving in sand or mud
• Maintain slow and constant speed.
• Use tire chains driving in mud if
necessary.
• Keep sufficient distance between your
vehicle and the vehicle in front of you.
• Reduce vehicle speed and always
check the road condition.
• Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent getting stuck.
CAUTION
When the vehicle is stuck in snow, sand
or mud, place a non-slip material under
the drive wheels to provide traction
OR Slowly spin the wheels in forward
and reverse directions which causes
a rocking motion that may free the
vehicle. However, avoid running the
engine continuously at high RPM, doing
so may damage the AWD system.

Driving up or down hills
• Driving uphill
-Before starting off, check if it is
possible to drive uphill.
-Drive as straight as possible.
• Driving downhill
-Do not change gear while driving
downhill. Select gear before driving
downhill.
-Drive as slowly using engine braking
while driving downhill.
-Drive straight as possible.
WARNING
Exercise extreme caution driving up or
down steep hills. The vehicle may flip
depending on the grade, terrain and
water/ mud conditions.
OLMB053018
WARNING
Do not drive across the contour of steep
hills. A slight change in the wheel angle
can destabilize the vehicle, or a stable
vehicle may lose stability if the vehicle
stops its forward motion. Your vehicle
may roll over and lead to a serious injury
or death.
Driving through water
• Try to avoid driving in deep standing
water. It may stall your engine and
clog your exhaust pipes.
• If you need to drive in water, stop
your vehicle, set the vehicle in AWD
LOCK mode and drive under 8 km/h
(5 mph).
• Do not change gear while driving in
water.
Additional driving conditions
• Become familiar with the off-road
conditions before driving.
• Always pay attention when driving off-
road and avoid dangerous areas.
• Drive slowly when driving in heavy
wind.
• Reduce vehicle speed when
cornering. The center of gravity
of AWD vehicles is higher than
conventional 2WD vehicles, making
them more likely to roll over when you
rapidly turn corners.

WINTER DRIVING
The severe weather conditions of winter
quickly wear out tires and cause other
problems. To minimize winter driving
problems, you should take the following
suggestions:
Snow or icy conditions
You need to keep sufficient distance
between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid
acceleration, sudden brake applications,
and sharp turns are potentially
very hazardous practices. During
deceleration, use engine braking to the
fullest extent. Sudden brake applications
on snowy or icy roads may cause the
vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires or to
install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to carry
include tire chains, tow straps or chains,
a flashlight, emergency flares, sand, a
shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket,
etc.
Snow tires
WARNING
Snow tires should be equivalent in size
and type to the vehicle’s standard tires.
Otherwise, the safety and handling of
your vehicle may be adversely affected.
We recommend that you use snow tires
when road temperature is below 45°F
(7°C). Refer to the below chart, and
mount the recommended snow tire for
your vehicle.
If you mount snow tires on your vehicle,
make sure to use the same Inflation
pressure as the original tires. Mount
snow tires on all four wheels to balance
your vehicle’s handling in all weather
conditions. The traction provided by
snow tires on dry roads may not be as
high as your vehicle’s original equipment
tires. Check with the tire dealer for
maximum speed recommendations.

Check spark plugs and ignition system
Inspect the spark plugs, as specified in
chapter 8. If necessary, replace them.
Also check all ignition wirings and
components for any cracks, wear-out,
and damage.
To prevent locks from freezing
To prevent the locks from being frozen,
spray approved de-icing fluid or glycerin
into key holes. When a lock opening is
already covered with ice, spray approved
de-icing fluid over the ice to remove it.
When an internal part of a lock freezes,
try to thaw it with a heated key. Carefully
use the heated key to avoid an injury.
Use approved window washer anti-
freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as specified
on the window washer container.
Window washer anti-freeze solution is
available from an authorized HYUNDAI
dealer, and most vehicle accessory
outlets. Do not use engine coolant or
other types of anti-freeze solution, to
prevent any damage to the vehicle paint.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.

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.
