ESC operation
ESC ON condition
When the Engine Start/Stop button is
in the ON position, the ESC and the
ESC OFF indica
tor lights illuminate for
approximately three seconds. After both
lights go off, the ESC is enabled.
When operating
When the ESC is in operation,
the ESC indicator light blinks:

[ When you apply your brakes under
conditions which may lock the wheels,
you may hear sounds from the brakes,
or feel a corresponding sensation in
the brake pedal. This is normal and it
means your ESC is active.

[ When ESC activates, the engine may
not respond to the accelerator as it
does under routine conditions.

[ If Cruise Control was in use when
the ESC activates, Cruise Control
automatically disengages. Cruise
Control can be reengaged when the
road conditions allow. See “Cruise
Control (CC)” section in chapter 7 (if
equipped).

[ When moving out of the mud or
driving on a slippery road, the engine
RPM (revolutions per minute) may
not increase even if you press the
accelerator pedal deeply. This is to
maintain the stability and traction of
the vehicle and does not indicate a
problem. ESC OFF condition
To cancel ESC operation:

[ State 1
Press the ESC OFF button briefly.
The ESC OFF indicator light and/or
message “Traction Control disabled”
will illuminate. In this state, the traction
control function of ESC (engine
management) is disabled, but the
brake control function of ESC (braking
management) still operates.

[ State 2
Press and hold the ESC OFF button
continuously for more than 3 seconds.
The ESC OFF indicator light and/or
message “Traction & Stability Control
disabled” illuminates and a warning
chime sounds. In this state, both the

management) and the brake control
function of ESC (braking management)
are disabled.
If the ignition switch is placed in the
LOCK/OFF position when ESC is off, ESC
remains off. Upon restarting the vehicle,
ESC will automatically turn on again.

Vehicle Stability Management
(VSM)
Vehicle Stability Management is a
function of the Electronic Stability
Control (ESC) system. It helps the vehicle
stay stable when accelerating or braking
suddenly on wet, slippery and rough
roads where traction over the four tires
can suddenly become uneven.
WARNING
Take the following precautions when
using Vehicle Stability Management :

[ALWAYS check the speed and the
distance to the vehicle ahead. VSM
is not a substitute for safe driving
practices.

[ Never drive too fast for the road
conditions. VSM system will not
prevent accidents. Excessive speed
in bad weather, on slippery and
uneven roads can result in severe
accidents.
VSM operation
VSM ON condition
VSM operates when:
Electr

onic Stability Control (ESC) is on.
When operating
When you apply your brakes under
conditions which ma
y activate ESC, you
may hear sounds from the brakes, or feel
a corresponding sensation in the brake
pedal. This is normal and it means your
VSM is active.
Information
The VSM does not operate when:

[ Driving on a banked road such as
gradient or incline.

[ Driving in reverse.

[ The ESC OFF indicator light is on.

[ The MDPS (Motor Driven Power
Steering) warning light (
) is on or
blinks.

Driving Your Vehicle6-32
VSM OFF condition
To cancel VSM operation, press the ESC
OFF butt
on. ESC OFF indicator light ()

To turn on VSM, press the ESC OFF
button again. The ESC OFF indicator light
will go out.
WARNING
If the ESC indicator light () or MDPS
warning light () stays illuminated
or blinks, your vehicle may have a
malfunction with the VSM system.
When the warning light illuminates
have the vehicle checked by an
authorized HYUNDAI dealer as soon as
possible.
NOTICE
Driving with wheels and tires with
different sizes may cause the VSM
system to malfunction. Before replacing
tires, make sure all four tires and wheels
are the same size. Never drive the
vehicle with different sized tires and
wheels installed.
Hill-Start Assist Control (HAC)
Hill-Start Assist Control 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 (maximum of 5 seconds
when the accelerator pedal is slightly
depressed during HAC operation) and
releases the brake after 2 seconds or
when the accelerator pedal is depressed.
WARNING
Always be ready to depress the
accelerator pedal when starting off
an incline. Hill-Start Assist Control
activates only for approximately 2
seconds (maximum of 5 seconds
when the accelerator pedal is slightly
depressed during HAC operation).
Information

[ Hill-Start Assist Control does not
operate when the gear is shifted to P
(Park) or N (Neutral).

[ Hill-Start Assist Control activates even
when the ESC (Electronic Stability
Control) is off. However, it does not
activate, when ESC does not operate
normally.

Good Braking Practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Move the shift button into the P
(Park) position, then apply the parking
brake, and set the Engine Start/Stop
button in the OFF position.
Vehicles parked with the parking brake
not applied or not fully engaged may
roll inadvertently and may cause injury
to the driver and others. ALWAYS apply
the parking brake before exiting the
vehicle. 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. 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 driving,
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 forward.

WARNING
If AWD warning light () stays on the
instrument cluster, your vehicle may
have a malfunction with the AWD
system. When the AWD warning light
(
) illuminates have vehicle checked by
an authorized HYUNDAI dealer as soon
as possible.
NOTICE

[ Maintain AWD Auto mode when
driving on roads in normal
conditions.

[ When driving under normal road
conditions (especially when
cornering) in AWD Lock mode, a
driver may find minor mechanical
vibration or noise, which is extremely
normal phenomenon, not a
malfunction. When AWD Lock mode
is released, such noise or vibration
will be immediately gone.
CAUTION
When driving on normal roads,
deactivate the AWD LOCK mode by
pushing the AWD LOCK button (AWD
LOCK indicator light goes off). Driving
on normal roads with the AWD LOCK
mode, especially, when cornering
may cause mechanical noise or
vibration. The noise and vibration will
disappear when the AWD LOCK mode is
deactivated. Prolonged driving with the
noise and vibration may damage some
parts of the power train.
NOTICE
When the AWD LOCK mode is
deactivated, a sensation may be felt as
the driving power is delivered entirely
to the front wheels.
Auto All Wheel Drive mode
(normal driving)
If the AWD system determines there is a
need for four wheel drive, the engine's
driving power is distributed to all four
wheels automatically.
For safe AWD operation
Before driving

[Mak
e sure all passengers are wearing
seat belts.

[ Sit upright and closer to the steering
wheel than usual. Adjust the steering
wheel to a position comfortable for
you to drive.
