Driving your vehicle
The paddle shifter is used to adjust
the regenerative braking rate from 0
to 3 during decelerating or braking.
Left side ( ): Increases regener-ative braking and deceleration.
Right side ( ): Decreases regenerative braking and decelera-
tion.
Pull and hold the left side paddle shifter to change to 0.
Pull and hold the left side paddle shifter to change to 3.
Information
The paddle shifter does not operate
when:
• Both Paddle shifters are pulled atthe same time.
• The Smart Cruise Control system is activated.
• The vehicle is shifted to P (Park), R (Reverse) and N (Neutral).
If the battery is fully charged when
descending down a long or steep
hill, the regenerative braking is
not working even though operat-
ing the paddle shifter. In this case,
depress the brake pedal to brake
the vehicle. This is normal and
does not indicate a problem with
your paddle shifter and brakes. The selected regenerative braking
rate is displayed on the instrument
cluster.
What Does Regenerative
Braking Do?
It uses the electric motor when
decelerating or braking which trans-
forms vehicle motion (kinetic energy)
to electrical energy to charge the
high voltage batteries.

Power Brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the power is not supplied such as
battery discharge, the power assist
for the brakes will not work. You can
still stop your vehicle by applying
greater force to the brake pedal than
typical. The stopping distance, how-
ever, will be longer than with power
brakes.
Do not pump the brake pedal when
the power assist has been interrupt-
ed.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.

Driving your vehicle
Take the following precautions:
Do not drive with your foot
resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
When descending down a
long or steep hill, use the pad-
dle shifter (left side lever) to
increase regenerative braking
control in order to control
your speed without using the
brake pedal excessively.
Applying the brakes continu-
ously will cause the brakes to
overheat and could result in a
temporary loss of braking per-
formance.
Wet brakes may impair the
vehicle's ability to safely slow
down; the vehicle may also
pull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water. To dry the brakes, light-
ly tap the brake pedal to heat
up the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.WARNING

Do not continue depressing thebrake pedal if the " "indica-
tor is OFF. The battery may be
discharged.
Noise and vibration generated during braking is normal.
Under normal operation, electric brake pump noise and motor
vibration may occur temporarily
in below cases.
- When the pedal is depressedsuddenly.
- When the pedal is repeatedly depressed in short intervals.
- When the ABS function is acti- vated while braking.
Disc Brake Wear Indicator
When your brake pads are worn and
new pads are required, you will hear
a high pitched warning sound from
your front or rear brakes. You may
hear this sound come and go or it
may occur whenever you depress
the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does
not indicate a problem with your
brakes.
To avoid costly brake repairs, do
not continue to drive with worn
brake pads.
Information
Always replace brake pads as com-
plete front or rear axle sets.
Electronic Parking Brake
(EPB)
Applying the parking brake
To apply the EPB (Electronic
Parking Brake):
1. Depress the brake pedal.
2. Pull the EPB switch upwards.
Make sure the Parking Brake
Warning Light comes on.
With the AUTO HOLD feature
enabled, the EPB is automatically
applied when the vehicle is shut off.

ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing wheel movement can still cause
your vehicle to veer into oncoming
traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake sys-
tem may result in a longer stopping
distance than for vehicles equipped
with a conventional brake system.
The ABS warning light ( ) will stay
on for several seconds after the
POWER button is in the ON position.
During that time, the ABS will go
through self-diagnosis and the light
will go off if everything is normal. If
the light stays on, you may have a
problem with your ABS. Contact an
authorized HYUNDAI dealer as soon
as possible.When you drive on a road having
poor traction, such as an icy road,
and apply your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light ( ) may illuminate. Pull
your car over to a safe place and
turn the vehicle off.
Restart the vehicle. If the ABS
warning light is off, then your ABS
system is normal.
Otherwise, you may have a prob-
lem with your ABS system.
Contact an authorized HYUNDAI
dealer as soon as possible.
Information
When you jump start your vehicle
because of a drained battery, the ABS
warning light ( ) may turn on at the
same time. This happens because of
the low battery voltage. It does not
mean your ABS is malfunctioning.
Have the battery recharged before
driving the vehicle.
i
NOTICE
Driving your vehicle
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, contact your
HYUNDAI dealer as soon as
possible.
WARNING

Driving your vehicle
The drive mode may be selected
according to the driver's preference
or road condition.
The system resets to be in the NOR-
MAL mode (except if it is in ECO
mode), when the vehicle is restarted.
Information
If there is a problem with the instru-
ment cluster, the drive mode will be in
NORMAL mode and may not change
to ECO mode. The mode changes, as below,
whenever the DRIVE MODE button
is pressed.
Press and hold the DRIVE MODE
button to select ECO+ mode.
ECO mode
ECO mode improves bat-tery charge use efficiency
for eco-friendly driving.
When ECO mode is selected by pressing the DRIVE MODE button,
the ECO indicator (green color) will
illuminate.
If the vehicle is set to ECO mode, when the vehicle is turned OFF
and restarted the Drive Mode set-
ting will remain in ECO mode.
Information
Battery charge use efficiency depends
on the driver's driving habit and road
condition. When ECO mode is activated:
The acceleration response may be
slightly reduced as the accelerator
pedal is depressed moderately.
The air conditioner performance may be limited.
The above situations are normal
conditions when ECO mode is acti-
vated to improve fuel efficiency.

Driving your vehicle
If you believe your brakes may be wet, apply them lightly while driv-
ing until normal braking operation
returns.
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 increas-
es as the depth of tire tread
decreases, refer to "Tire Tread" in
chapter 7.
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 sev-
eral 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 speci-
fied on your tires.
Coolant and high voltage bat-tery
Be sure to check both the coolant
level and the high voltage battery
level before driving.
i

5-124
Driving your vehicle
When using tire chains:
Wrong size chains or improperly installed chains can damage
your vehicle's brake lines, sus-
pension, 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 vehi- cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 0.47 in (12 mm) thick to prevent damage
to the chain's connection.
Winter Precautions
Use high quality ethylene glycolcoolant
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 cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Change to "winter weight" oil ifnecessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.
