great force and enter the passenger
compartment, which could result in
serious injury or death.
WARNING
Make sure the engine is off, the shift
lever is in P (Park), and the parking
brake is securely applied whenever
loading or unloading cargo. Failure to
take these steps may allow the vehicle
to move if the shift lever is inadvertently
moved to another position.
CAUTION
• Be careful when loading cargo
through the rear passenger seats
to prevent damage to the vehicle
interior.
• When cargo is loaded through the
rear passenger seats, ensure the
cargo is properly secured to prevent
it from moving while driving.
WARNING
Cargo should always be secured to
prevent it from being thrown about the
vehicle in a collision and causing injury
to the vehicle occupants. Do not place
objects in the rear seats, since they
cannot be properly secured and may hit
the front seat occupants in a collision.

VSM OFF condition
To cancel VSM operation, press the ESC
OFF button. ESC OFF (
) indicator light
will illuminate.
To turn on VSM, press the ESC OFF
button again. The ESC OFF indicator light
will go out.
WARNING
If the ESC () indicator light or EPS
() warning light stays illuminated
or blinks, your vehicle may have a
malfunction with the VSM system.
When the warning light illuminates
we recommend that the vehicle be
checked by an authorized HYUNDAI
dealer as soon as possible.
NOTICE
Driving with wheels and tires with
different sizes may cause the VSM
system to malfunction. Before replacing
tires, make sure all four tires and wheels
are the same size. Never drive the
vehicle with different sized tires and
wheels installed.
Trailer stability assist (TSA)
Trailer stability assist is operated as a
vehicle stability control system. The
Trailer stability assist system stabilizes
the vehicle and trailer when the trailer
sways or oscillates. There are various
reasons making vehicle sway and
oscillate. In most case it happens at high
speed however, if the trailer is affected
by crosswinds, buffeting, and improper
overloading, it may also be a risk of sway.
Factors of swaying such as:
- High speed
-Strong crosswinds
-Improper overloading
-Sudden controlling of steering wheel
-Uneven road
Trailer stability assist system
continuously analyzes the vehicle
and trailer instability. When the
Trailer stability assist system detects
some sway, the brakes are applied
automatically to stabilize the vehicle
on the front wheel. However, if it is
not enough to stabilize, the brakes are
applied on all wheels automatically and
engine power is properly reduced. When
the vehicle is stable from swaying, trailer
stability assist system does not operate.

• Always hold the steering wheel firmly
when you are driving off-road.
WARNING
Do not grab the inside of the steering
wheel when you are driving off-road.
You may hurt your arm by a sudden
steering maneuver or from steering
wheel rebound due to an impact with
objects on the ground. You could lose
control of the steering wheel which may
lead to serious injury or death.
Emergency precautions
Tires
Do not use tire and wheel with different
size and type from the one originally
installed on your vehicle. It can affect the
safety and performance of your vehicle,
which could lead to steering failure or
rollover causing serious injury.
When replacing the tires, be sure to
equip all four tires with the tire and wheel
of the same size, type, tread, brand and
load-carrying capacity. If you equip your
vehicle with any tire/wheel combination
not recommended by HYUNDAI for off-
road driving, you should not use these
tires for highway driving.
WARNING
Never start or run the engine while a
full-time AWD vehicle is raised on a
jack. The vehicle can slip or roll off of a
jack causing serious injury or death to
you or those nearby.
Towing
AWD 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" in chapter 8.
Dynamometer testing
A full-time AWD vehicle must be
tested on a special four wheel chassis
dynamometer.

Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or fail the
braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.
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 vehicle
with heavy cargo on the roof, and never
modify your vehicle in any way.
WARNING
Utility vehicles have a significantly
higher rollover rate than other types of
vehicles. To prevent rollovers or loss of
control:
• Take corners at slower speeds than
you would with a passenger vehicle.
• Avoid sharp turns and abrupt
maneuvers.
• Do not modify your vehicle in any
way that you would raise the center
of gravity.
• Keep tires properly inflated.
• Do not carry heavy cargo on the roof.
WARNING
In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt. Make sure
all passengers are wearing their seat
belts.

If you decide to pull a trailer?
Here are some important points if you
decide to pull a trailer:
• Consider using a sway control. You
can ask a trailer hitch dealer about
sway control.
• Do not do any towing with your
vehicle during its first 1,200 miles
(2,000 km) in order to allow the
engine to properly break in. Failure to
heed this caution may result in serious
engine or transmission damage.
• When towing a trailer, we
recommend that you consult an
authorized HYUNDAI dealer for
further information on additional
requirements such as a towing kit, etc.
• Always drive your vehicle at a
moderate speed (less than 60 mph
(100 km/h)) or posted towing speed
limit.
• On a long uphill grade, do not exceed
45 mph (70 km/h) or the posted
towing speed limit, whichever is
lower.
• Carefully observe the weight and load
limits provided in the following pages.
Trailer weight
Tongue LoadTotal Trailer Weight
OOSH069129L
What is the maximum safe weight of a
trailer? It should never weigh more than
the maximum trailer weight with trailer
brakes. But even that can be too heavy.
It depends on how you plan to use your
trailer. For example, speed, altitude,
road grades, outside temperature and
how often your vehicle is used to pull a
trailer are all important. The ideal trailer
weight can also depend on any special
equipment that you have on your vehicle.

06
6-67
Tongue load
Gross Axle WeightGross Vehicle Weight
OOSH069130L
The tongue load is an important weight
to measure because it affects the
total Gross Vehicle Weight (GVW) of
your vehicle. The trailer tongue should
weigh a maximum of 10% of the total
loaded trailer weight, within the limits
of the maximum trailer tongue load
permissible.
After you’ve loaded your trailer,
weigh the trailer and then the tongue,
separately, to see if the weights are
proper. If they aren’t, you may be able
to correct them simply by moving some
items around in the trailer.
WARNING
Take the following precautions:
• Never load a trailer with more weight
in the rear than in the front. The front
should be loaded with approximately
60% of the total trailer load; the rear
should be loaded with approximately
40% of the total trailer load.
• Never exceed the maximum weight
limits of the trailer or trailer towing
equipment. Improper loading can
result in damage to your vehicle and/
or personal injury. Check weights
and loading at a commercial scale or
highway patrol office equipped with
scales.
Information
With increasing altitude the engine
performance decreases. From 1,000 m
above sea level and for every 1,000 m
thereafter 10% of vehicle/trailer weight
(trailer weighter + gross vehicle weight)
must be deducted.

NOTICE
To prevent engine and/or transmission
overheating:
• When towing a trailer on steep
grades (in excess of 6%) pay close
attention to the engine coolant
temperature gauge to ensure the
engine does not overheat. If the
needle of the coolant temperature
gauge moves towards “H” (HOT),
pull over and stop as soon as it is
safe to do so, and allow the engine
to idle until it cools down. You may
proceed once the engine has cooled
sufficiently.
• If you tow a trailer with the maximum
gross vehicle weight and maximum
trailer weight, it can cause the
engine or transmission to overheat.
When driving in such conditions,
allow the engine to idle until it cools
down. You may proceed once the
engine or transmission has cooled
sufficiently.
• When towing a trailer, your vehicle
speed may be much slower than the
general flow of traffic, especially
when climbing an uphill grade. Use
the right hand lane when towing a
trailer on an uphill grade. Choose
your vehicle speed according to the
maximum posted speed limit for
vehicles with trailers, the steepness
of the grade, and your trailer weight.
Parking on hills
Generally, if you have a trailer attached
to your vehicle, you should not park your
vehicle on a hill.
However, if you ever have to park your
trailer on a hill, here’s how to do it:
1. Pull the vehicle into the parking space.
Turn the steering wheel in the
direction of the curb (right if headed
down hill, left if headed up hill).
2. Shift the gear to P (Park).
3. Set the parking brake and shut off the
vehicle.
4. Place wheel chocks under the trailer
wheels on the down hill side of the
wheels.
5. Start the vehicle, hold the brakes, shift
to neutral, release the parking brake
and slowly release the brakes until the
trailer chocks absorb the load.
6. Reapply the brakes and parking
brakes.
7. Shift the gear to P (Park) when the
vehicle is parked on a uphill grade and
in R (Reverse) on a downhill.
8. Shut off the vehicle and release the
vehicle brakes but leave the parking
brake set.
WARNING
To prevent serious or fatal injury:
• Do not get out of the vehicle without
the parking brake firmly set. If you
have left the engine running, the
vehicle can move suddenly. You and
others could be seriously or fatally
injured.
• Do not apply the accelerator pedal to
hold the vehicle on an uphill.

06
6-73
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 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,
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.
