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.

Collision Warning
(First warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs to help
decelerate the vehicle. If FCA detects a vehicle in front,
the system operates when your
vehicle speed is between 5 mph (8
km/h) and 40 mph (65 km/h).
Maximum vehicle speed may
decrease depending on the condi-
tion of the vehicle ahead and sur-
roundings.
If FCA detects a pedestrian in
front, the system operates when
your vehicle speed is between 5
mph (8 km/h) and 40 mph (65
km/h). Maximum vehicle speed
may decrease depending on the
condition of the pedestrian and
surroundings.
If you select 'Warning only' for the
system setting, FCA system acti-
vates and produces only warning
alarms in accordance with the col-
lision risk levels. You should control
the brake directly because FCA
system will not control the brake.
Emergency braking
(Second warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs to help
decelerate the engine.
If FCA detects a vehicle in front,
the system operates when your
vehicle speed is above 5 mph (8
km/h) and less than or equal to 110
mph (180 km/h). Maximum vehicle
speed may decrease depending
on the condition of the vehicle
ahead and surroundings.
