Driving your vehicle
Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
backwards when starting a vehicle
from a stop on a hill. The system
operates the brakes automatically for
approximately 2 seconds and releas-
es the brake after 2 seconds or when
the accelerator pedal is depressed.
Information
• HAC does not operate when the shift
lever is in P (Park) or N (Neutral).
• HAC activates even when the ESC
(Electronic Stability Control) is off.
However, it does not activate, when
ESC does not operate normally.
Good Braking Practices
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop
as quickly if the brakes are wet. Wet
brakes may cause the vehicle to pull
to one side.To dry the brakes, apply the brakes
lightly until the braking action returns
to normal, taking care to keep the
vehicle under control at all times. If
the braking action does not return to
normal, stop as soon as it is safe to
do so and call an authorized
HYUNDAI dealer for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, but
constant pedal pressure can result in
the brakes overheating, brake wear,
and possibly even brake failure.
If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe location.
Keep your foot firmly on the brake
pedal when the vehicle is stopped to
prevent the vehicle from rolling for-
ward.
i
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Move
the shift lever into P (Park) posi-
tion, then apply the parking
brake, and place the Engine
Start/Stop button in the OFF
position.
Vehicles parked with the park-
ing brake not applied or not
fully engaged may roll inadver-
tently and may cause injury to
the driver and others. ALWAYS
apply the parking brake before
exiting the vehicle.
WARNING
Always be ready to depress the
accelerator pedal when starting
off an incline. The HAC activates
only for approximately 2 sec-
onds.

Driver Attention Warning sys-
tem may not provide alerts in
the following situations:
The system may not work
around 15 seconds after start-
ing the vehicle or the initial-
ization or rebooting of the
front view camera.
The lane detection perform-
ance is limited. (For more
information, refer to "Lane
Keeping Assist (LKA)" in this
chapter.)
The vehicle is erratically driv-
en or is abruptly turned for
obstacle avoidance (e.g. con-
struction area, other vehicles,
fallen objects, bumpy road).
(Continued)
CAUTION(Continued)
Forward drivability of the
vehicle is severely under-
mined (possibly due to wide
variation in tire pressures,
uneven tire wear-out, toe-
in/toe-out alignment).
The vehicle is driven on a
curvy road.
The vehicle is driven through
a windy area.
The vehicle is driven on a
bumpy road.
The vehicle is controlled by
the following driving assist
systems:
- Forward Collision-Avoidance
Assist system

change may cause a delay in
the system's reaction or may
cause the system to react to a
vehicle actually in an adjacent
lane. Always drive cautiously
to prevent unexpected and
sudden situations from occur-
ring.
Always be aware of the select-
ed speed and vehicle to vehi-
cle distance. The driver

Driving your vehicle
Driving too fast through large pud-
dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly.
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
adversely affect vehicle handling.
This could lead to sudden tire failure
that may cause loss of vehicle con-
trol resulting in an accident.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Fuel, engine coolant and engine
oil
Driving at higher speeds on the high-
way 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.
i
In a rollover crash, an unbelted
person is significantly more
likely to die than a person wear-
ing a seat belt. Make sure all
passengers are wearing their
seat belts.
