Good braking practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Shift the gear to the P (Park)
position, then apply the parking brake,
and press the Engine Start/Stop button
to the OFF position.
Vehicles parked with the parking brake
not applied or not fully engaged may
roll inadvertently and may cause injury
to the driver and others. ALWAYS apply
the parking brake before exiting the
vehicle.Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop as
quickly if the brakes are wet. Wet brakes
may cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns to
normal. If the braking action does not
return to normal, stop as soon as it is safe
to do so and we recommend that you
call an authorized HYUNDAI dealer for
assistance.
DO NOT drive with your foot resting on
the brake pedal. Even light, but constant
pedal pressure can result in the brakes
overheating, brake wear, and possibly
even brake failure.
If a tire goes flat while you are driving,
apply the brakes gently and keep the
vehicle pointed straight ahead while you
slow down. When you are moving slowly
enough for it to be safe to do so, pull off
the road and stop in a safe location.
Keep your foot firmly on the brake pedal
when the vehicle is stopped to prevent
the vehicle from rolling forward.

Four Wheel Drive (4WD) delivers engine
power to front and rear wheels for
maximum traction. 4WD is useful when
extra traction is required, such as when
driving on, muddy, wet, or snow-covered
roads.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:
• Do not drive in conditions that
exceed the vehicles intended
design such as challenging off-road
conditions.
• Avoid high speeds when cornering or
turning.
• Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.
• The risk of a rollover is greatly
increased if you lose control of your
vehicle at highway speeds.
• Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.
• In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
NOTICE
• Do not drive in water if the level
is higher than the bottom of the
vehicle.
• Check your brake condition once
you are out of mud or water. Depress
the brake pedal several times as you
move slowly until you feel normal
braking return.
• Shorten your scheduled
maintenance interval if you drive in
off-road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage Conditions"
section in chapter 9).
• Always wash your vehicle thoroughly
after off road use, especially the
bottom of the vehicle.
• Be sure to equip the vehicle with four
tires of the same size and type.
• Make sure that a full time 4WD
vehicle is towed by a flat bed tow
truck.

For safe 4WD 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.
• Apply engine braking during
deceleration by using the paddle
shifter (manual shift mode) and
manually selecting a lower gear.
• Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent skids.
Information
When using Snow Tires, mount them on
all four wheels.
If a full set of chains is not available for
an 4WD vehicle when using tire chains,
chains may be installed on the front wheels
only.
For more details on Snow Tires and Tire
Chains, refer to "Winter Driving" section
later in this chapter.
CAUTION
Mud or snow
If one of the front or rear wheels
begins to spin in mud, snow, etc. the
vehicle can sometimes be driven out by
engaging the accelerator pedal further;
however avoid running the engine
continuously at high rpm because doing
so could damage the AWD system.
Driving in sand or mud
• Maintain slow and constant speed.
Operate the accelerator pedal slowly
to ensure safe driving (wheel-slip
prevention).
• 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.
• When the vehicle is stuck in snow,
sand or mud, the tires may not
operate.
• This is to protect the transmission and
not a malfunction.
NOTICE
Moving the vehicle forcibly to get out
of mud or sand can cause damage/
overheat of the engine or damage/
breakdown of the transmission,
differential or 4WD system as well as
damage to tires. If excessive wheel slip
occurs after entering a sandy/muddy
road, the vehicle may fall into the sand/
mud. When it happens, put a stone or
a tree branch under the tire, and then
try to pull out the vehicle, or try to get it
unstuck by repeatedly moving forwards
and backwards.

Transmission overheated
• When driving on muddy and sandy
roads under the severe condition, the
transmission could be overheated.
• When the transmission is overheated,
the safe protection mode engages
and the “Transmission Hot! Park with
engine on: warning message will
appear on the LCD display with a
chime.
• If this occurs, pull over to a safe
location, stop the vehicle with the
engine running, apply the brakes and
shift the vehicle to P (Park), and allow
the transmission to cool.
• If you ignore this warning, the driving
condition may become worse.
You may experience abrupt shifts,
frequent shifts, or jerkiness. To return
to the normal driving condition, stop
the vehicle and apply the foot brake
or shift into P (Park). Then allow the
transmission to cool for a few minutes
with engine on, before driving off. •
When the message “Trans cooled.
Resume driving” appears you can
continue to drive your vehicle.
• If the warning messages in the LCD
display continue to blink, for your
safety, have the system checked
by a professional workshop. We
recommends to visit an authorized
HYUNDAI dealer.
Driving up or down hills
• Driving uphill
- Bef
ore starting off, check if it is
possible to drive uphill.
- Drive as s
traight as possible.
• Driving downhill
- Do not change gear while driving
do
wnhill. Select gear before driving
downhill.
- Drive slo
wly using engine braking
while driving downhill. - Drive s traight as possible.
WARNING
Exercise extreme caution driving up or
down steep hills. The vehicle may flip
over depending on the grade, terrain,
water and mud conditions.
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.

Towing
4WD vehicles must be towed with
a wheel lift and dollies or flatbed
equipment with all the wheels off the
ground. For more details, refer to
"Towing" section in chapter 8.
Vehicle inspection
• If the vehicle needs to be operated on
a vehicle lift do not attempt to stop
any of the four wheels from turning.
This could damage the 4WD system.
• Never engage the parking brake while
running the engine on a car lift. This
may damage the 4WD system.
Dynamometer testing
An 4WD vehicle must be tested on a
special four wheel chassis dynamometer.
OTM060016L[A] : Roll tester (Speedometer),
[B] : Temporary free roller
An 4WD vehicle should not be tested
on a 2WD roll tester. If a 2WD roll tester
must be used, perform the following
procedure:
1.
Check the tire pr

essures
recommended for your vehicle.
2.
Place the rear wheels on the r

oll tester
for a speedometer test as shown in
the illustration.
3.
Release the parking br

ake.
4.
Place the fron

t wheels on the
temporary free roller as shown in the
illustration.
WARNING
Keep away from the front of the vehicle
while the vehicle is in gear on the
dynamometer. The vehicle can jump
forward and cause serious injury or
death.
Reducing the risk of a rollover
Your multi-purpose passenger vehicle is
defined as a Sports Utility Vehicle (SUV).
SUV’s have higher ground clearance
and a narrower track to make them
capable of performing in a wide variety
of off-road applications. The specific
design characteristics give them a higher
center of gravity than ordinary vehicles
making them more likely to roll over if
you make abrupt turns. Utility vehicles
have a significantly higher rollover rate
than other types of vehicles. Due to this
risk, driver and passengers are strongly
recommended to buckle their seat belts.
In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt.
There are steps that a driver can make
to reduce the risk of a rollover. If at all
possible, avoid sharp turns or abrupt
maneuvers, do not load your roof rack
with heavy cargo, and never modify your
vehicle in any way.
