Driving Your Vehicle6-48
Various driving situations, which you may
encounter in SMART mode

[ The driving mode aut
omatically
changes to ECO mode after a certain
period of time, when you gently
depress the accelerator pedal (Your
driving is categorized to be mild.).

[ The driving mode automatically
returns to SMART ECO mode, when
the vehicle enters a leveled road.

[ The driving mode automatically
changes to SMART SPORT, when
you abruptly accelerate the vehicle
or repetitively operate the steering
wheel (Your driving is categorized
to be sporty.). In this mode, your
vehicle drives in a lower gear for
abrupt accelerating/decelerating
and increases the engine brake
performance.

[ You may still sense the engine brake
performance, even when you release
the accelerator pedal in SMART
SPORT mode. It is because your
vehicle remains to be in a lower gear
over a certain period of time for next
acceleration. Thus, it is a normal
driving situation, not indicating any
malfunction.

[ The driving mode automatically
changes to SMART SPORT mode only
in harsh driving situations. In most
of the normal driving situations, the
driving mode sets to be either in
SMART ECO mode. Limitation of SMART mode
The SMART mode may be limited in
f
ollowing situations. (The OFF indicator
illuminates in those situations.)

[ The vehicle is driven using the paddle
shifter (manual shift mode) : SMART
mode is deactivated determining that
the driver wants to drive the vehicle
manually.

[ Cruise Control and Smart Cruise
Control is activated : Cruise Control
and Smart Cruise Control may
deactivate SMART mode when
the vehicle is controlled by the set
speed of Cruise Control and Smart
Cruise Control. (SMART mode is not
deactivated just by turning on Cruise
Control and Smart Cruise Control)

[ The transmission oil temperature is either
extremely low or extremely high : The
SMART mode can be active in most of
the normal driving situations. However,
an extremely high/ low transmission oil
temperature may temporarily deactivate
the SMART mode, because the
transmission condition is out of normal
operation condition.

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.

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.
If the vehicle is not used for a long time,
park the vehicle indoors if possible.
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, consult
an authorized HYUNDAI dealer.Check spark plugs and ignition system
Inspect the spark plugs, as specified in
chapter 9. 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.

Maintenance9-8
Information
• It is normal for engine oil to be consumed during driving. The engine oil level should
be checked on regular basis.
• The engine oil change interval for normal operating conditions is based on the use of
the recommended engine oil specification in chapter 2. If the recommended engine
oil specification is not used, then replace the engine oil according to the maintenance
schedule under severe operating conditions.
• The vehicle may be equipped with the Oil Life Management System that predicts
engine oil life based on the driver’s driving history and alerts the driver to change
engine oil.
- If the deterioration of the engine oil increases depending on the driver’s driving
style, the remaining oil life alert will appear on the instrument cluster before the
normal engine oil replacement interval. Have the engine oil and filter changed by an
authorized HYUNDAI dealer.
- Oil Life Management System works when the recommended engine oil is used.
If the recommended engine oil is not used, replace the engine oil according to the
maintenance schedule under severe usage conditions. Also, check the engine oil level
regularly as this system assumes that the engine oil is being filled norm\
ally.
- Always reset the remaining engine oil life whenever the engine oil is changed.
Otherwise, the indication of remaining Oil life in the Oil Life Management System
may not be accurate.To reset the Oil Change Reminder, select ‘RESET’ from the
instrument cluster or infotainment system screen. Then, select ‘Yes’ when the
message “Reset oil life?” or “Has the engine oil been changed? Press [Yes] to reset
the oil life.” appears on the screen.
- If there is no alert until the maximum maintenance interval, have the vehicle
checked by an authorized HYUNDAI dealer.
