Drive Mode
ONE1061021
Drive mode may be selected according
to the driver's preference or road condition.
ONE1061041
The mode changes whenever the driver
pushes the DRIVE MODE button. NORMAL mode
Normal mode is a driving mode used
when driving on general roads, city
center and highways. ECO mode
ECO mode is a driving mode improving
energy efficiency by controlling motors
and reduction gear.
Electric energy efficiency varies
according to the driver's driving habit
and road condition. •
When ECO mode is selected, the
ECO indicator will illuminate on the
instrument cluster and the color of the mood lamp will change.
• When ECO mode is activated:
- The acceleration response may be slightly reduced if the accelerator
pedal is depressed moderately.
- The air conditioner performance may be limited.
The above situations are normal
conditions when ECO mode is
activated to help improve electric
energy efficiency.
Limitations of ECO mode
If the following conditions occur while
ECO 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 motor
performance becomes normal.
• When driving up a hill:
The system will be limited to gain
power when driving uphill because
motor torque is restricted.

Limitations of ECO mode
If the following conditions occur while
ECO 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 motor
performance becomes normal.
• When driving up a hill:
The system will be limited to gain
power when driving uphill because
motor torque is restricted.
SPORT mode
SPORT mode is a driving mode
improving driving performance by fixing
AWD system and controlling reduction
gear.
In SPORT mode, the electric energy
efficiency may decrease. • When SPORT mode is selected, the
SPORT indicator will illuminate on the
instrument cluster and the color of the mood lamp will change.
• Whenever the vehicle is restarted,
the drive mode will revert back to
NORMAL mode. If SPORT mode is
desired, re-select SPORT mode.
SNOW mode
SNOW mode is a driving mode improving
driving performance by changing
the engagement status of the motor
according to the situation required. Auto
changing the driving mode(2WD/AWD)
helps improve driving stability. • Press and hold the drive mode button
to select SNOW mode.
• When SNOW mode is selected, the
SNOW indicator will illuminate on the
instrument cluster and the color of the mood lamp will change.
• When SNOW mode is activated, the
driving power is distributed to four
wheels automatically, increasing the
stability of the vehicle.
NOTICE
• Depress the accelerator pedal softly
on the snow and the ice.
• Keep the distance from the vehicle in
the front.
• Prevent rapid acceleration,
deceleration and steering control.
Abrupt driving on the snow may
cause the accident.

Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the water.
The best advice is SLOW DOWN when
the road is wet.
The risk of hydroplaning increases as
the depth of tire tread decreases, refer
to “Tire Tread” section in chapter 9.
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.
Coolant and high voltage battery
Driving at higher speeds on the highway
consumes more electric energy and is
less efficient than driving at a slower,
more moderate speed. Maintain a
moderate speed in order to conserve
electric energy when driving on the
highway.
Be sure to check both the coolant level
and the electric energy level before driving.

Winter Precautions
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.
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 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
motor compartment
Putting objects or materials in the motor
compartment may cause an motor
failure. Such damage will not be covered
by the manufacturer’s warranty.
