OAE056001
To turn the hybrid system off in
an emergency:
Press and hold the Engine
Start/Stop button for more than
two seconds OR Rapidly press
and release the Engine Start/
Stop button three times (within
three seconds).
If the vehicle is still moving, you
can restart the hybrid system
without depressing the brake
pedal by pressing the Engine
Start/Stop button with the shift
lever in the N (Neutral) position.
WARNING
•NEVER press the Engine
Start/Stop button while the
vehicle is in motion except in
an emergency. This will result
in the hybrid system turning
off and loss of power assist
for the steering and brake
systems. This may lead to
loss of directional control and
braking function, which could
cause an accident.
•Before leaving the driver's
seat, always make sure the
shift lever is in the P (Park)
position, set the parking brake,
press the Engine Start/Stop
button to the OFF position, and
take the Smart Key with you.
Unexpected vehicle movement
may occur if these precautions
are not followed.

Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the vehicle is not in the ready
( ) mode or the vehicle is turned
off while driving, 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, however, will
be longer than with power brakes.
When the vehicle is not in the ready
( ) mode, the reserve brake
power is partially depleted each time
the brake pedal is applied. Do not
pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.
BRAKING SYSTEM
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, move the
shift lever to Manual Shift
mode and manually downshift
to a lower gear in order to
control your speed without
using the brake pedal exces-
sively. Applying the brakes
continuously will cause the
brakes to overheat and could
result in a temporary loss of
braking performance.
(Continued)
(Continued)
•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.

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 EPS (Electric power steering)
warning light ( ) is on or blinks.
VSM OFF condition
To cancel VSM operation, press the
ESC OFF button. ESC OFF indicator
light ( ) will illuminate.
To turn on VSM, press the ESC OFF
button again. The ESC OFF indicator
light will go out.Driving with wheels and tires with
different sizes may cause the ESC
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.
NOTICEi
If the ESC indicator light ( ) or
EPS warning light ( ) stays
on or blinks, your vehicle may
have a malfunction with the
VSM system. When the warning
light illuminates we recommend
that the vehicle be checked by
an authorized HYUNDAI dealer
as soon as possible.

Brake operation
• In an urgent situation, the braking
system enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
• The AEB provides additional brak-
ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
• The braking control is automatical-
ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
• The AEB brake control is automat-
ically cancelled, when risk factors
disappear.The driver should always use
extreme caution while operating
the vehicle, whether or not there
is a warning message or alarm
from the AEB system.CAUTION
The braking control cannot
completely stop the vehicle nor
avoid all collisions. The driver
should hold the responsibility
to safely drive and control the
vehicle.
WARNING
The AEB system logic operates
within certain parameters, such
as the distance from the vehicle
or pedestrian ahead, the speed
of the vehicle ahead, and the
driver's vehicle speed. Certain
conditions such as inclement
weather and road conditions
may affect the operation of the
AEB system.
WARNING
Never deliberately drive danger-
ously to activate the system.

What to do in an emergency
6
Emergency towing
If towing is necessary, we recom-
mend you have it done by an author-
ized HYUNDAI dealer or a commer-
cial tow truck service.If a towing service is not available in
an emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook at the front (or rear) of the
vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. A
driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a
short distance and at low speeds.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.Always follow these emergency tow-
ing precautions:
• Place the ignition switch in the ACC
position so the steering wheel is
not locked.
• Place the shift lever in N (Neutral).
• Release the parking brake.
• Depress the brake pedal with more
force than normal since you will
have reduced braking perform-
ance.
• More steering effort will be required
because the power steering system
will be disabled.
• Use a vehicle heavier than your
own to tow your vehicle.
• The drivers of both vehicles should
communicate with each other fre-
quently.
• Before emergency towing, check
that the hook is not broken or dam-
aged.
• Fasten the towing cable or chain
securely to the hook.
• Do not jerk the hook. Apply steady
and even force.
