Limitations of ECO mode
If the following conditions occur while
E
CO mode is operating, the system
operation is limited even though there is
no change in the ECO indicator.

[ When coolant temperature is low:
The system will be limited until engine
performance becomes normal.

[ When driving up a hill:
The system will be limited to gain
power when driving uphill because
engine torque is restricted.

[ When driving the vehicle in manual
shift mode using the paddle shifter.
The system will be limited according to
the shift location.
SPORT mode
SPORT mode provides sporty
but firm riding.
In SPORT mode, the fuel
efficiency may decrease.

[ When SPORT mode is selected, the
SPORT indicator will illuminate on the
instrument cluster.

[ Whenever the engine is restarted, the
drive mode will revert back to ECO
mode. If SPORT mode is desired, re-
select SPORT mode.

[ When SPORT mode is activated:
- The engine rpm will tend to remain raised over a certain length of time
even after releasing the accelerator
- Upshifts are delayed when accelerating
SMART mode
SMART mode selects the
proper driving mode among
ECO, COMFORT and SPORT
by judging the driver's
driving habits (i.e. mild or
dynamic) from the brake pedal
depression or the steering
wheel operation.

[ Press the DRIVE MODE button to
activate SMART mode. When SMART
mode is activated, the indicator
illuminates on the instrument cluster.

[ The vehicle starts in SMART mode,
when the engine was turned OFF in
SMART mode.

[ SMART mode automatically controls
gear shifting patterns, engine torque,
in accordance with the driver's driving
habits.
Information

[When you mildly drive the vehicle
in SMART mode, the driving mode
changes to ECO mode to improve fuel
efficiency. However, the actual fuel
efficiency may differ in accordance
with your driving situations (for
example, upward/downward slope,
vehicle deceleration/acceleration).

[ When you dynamically drive the
vehicle in SMART mode by abruptly
decelerating or sharply curving, the
driving mode changes to SPORT mode.
However, it may adversely affect fuel
economy.

Driving Your Vehicle6-52
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.

Chain Installation
When installing tire chains, follow the
manuf
acturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 20 mph (30 km/h)) with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the tire chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park the
vehicle on level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emergency
warning device behind the vehicle (if
available). Always place the vehicle in P
(Park), apply the parking brake and turn
off the engine before installing snow
chains.
NOTICE
When using tire chains:

[ Wrong size chains or improperly
installed chains can damage your
vehicle’s brake lines, suspension,
body and wheels.

[ Use SAE “S” class or wire chains.

[ If you hear noise caused by chains
contacting the body, retighten the
chain to prevent contact with the
vehicle body.

[ To prevent body damage, retighten
the chains after driving 0.3~0.6 miles
(0.5~1.0 km).

[ Do not use tire chains on vehicles
equipped with aluminum wheels. If
unavoidable, use a wire type chain.

[ Use wire chains less than 0.47 in.
(12 mm) thick or fabric-type chain
to prevent damage to the chain’s
connection.

[ Fabric-type chains must be used on
vehicles equipped with 19/20” tires.
Winter Precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 9. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be checked
by an authorized HYUNDAI dealer or in a
service station.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity In
addition, replace the engine oil and filter
if it is close to the next maintenance
interval. Fresh engine oil ensures
optimum engine operation during the
winter months. For further information,
refer to chapter 2. When you are not sure
about a type of winter weight oil, you
consult an authorized HYUNDAI dealer.
