•NEVER turn the ignition
switch to the LOCK or ACC
position whilst the vehicle is
in motion except in an emer-
gency. This will result in the
engine turning off and loss of
power assist for the steering
and brake systems. This may
lead to loss of directional con-
trol and braking function,
which could cause an acci-
dent.

Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the engine is not running or is
turned off whilst 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 dis-
tance, however, will be longer than
with power brakes.
When the engine is not running, 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 a long or
steep hill, shift to a lower gear
and avoid continuous applica-
tion of the brakes. Applying
the brakes continuously will
cause the brakes to overheat
and could result in a tempo-
rary loss of braking perform-
ance.
(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 whilst maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.

VSM operation
VSM ON condition
The VSM operates when:
• The Electronic Stability Control
(ESC) is on.
• Vehicle speed is above approxi-
mately 15 km/h on a winding road.
• Vehicle speed is above approxi-
mately 20 km/h when the vehicle is
braking on rough roads.
When operating
When you apply your brakes under
conditions which may activate the
ESC, you may hear sounds from the
brakes, or feel a corresponding sen-
sation in the brake pedal. This is nor-
mal and it means your VSM is active.
Information
The VSM does not operate when:
• Driving on a banked road such as a
gradient or incline
• Driving rearward.
• ESC OFF indicator light is on.
• EPS (Electric Power Steering)
warning light ( ) is on.
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 varying tyre or wheel
sizes may cause the ESC system
to malfunction. When replacing
tyres, make sure they are the
same size as your original tyres
for this vehicle.
NOTICE
i
If the ESC indicator light ( ) or
EPS warning light ( ) stays
on, your vehicle may have a
malfunction with the VSM sys-
tem. When the warning light illu-
minates we recommend that the
vehicle be checked by an autho-
rised HYUNDAI dealer as soon
as possible.
WARNING

Driving your vehicle
When Active ECO is activated:
• The acceleration response may be
slightly reduced as the accelerator
pedal is depressed moderately.
• The air conditioner performance
may be limited.
• The shift pattern of the automatic
transaxle may change.
• The engine noise may get louder.
The above situations are normal
conditions when the Active ECO sys-
tem is activated to improve fuel effi-
ciency.Limitation of Active ECO opera-
tion:
If the following conditions occur
whilst Active ECO is operating, the
system operation is limited even
though there is no change in the
ECO indicator.
• When the coolant temperature is
low:
The system will be limited until
engine performance becomes nor-
mal.
• When driving up a hill:
The system will be limited to gain
power when driving uphill because
engine torque is restricted.
• When using the automatic
transaxle Sports mode:
The system will be limited accord-
ing to the shift location.
• When the accelerator pedal is
deeply depressed for a few sec-
onds: The system will be limited,
judging that the driver wants to
speed up.
SPORT mode
SPORT mode focuses on
dynamic driving by auto-
matically controlling the
steering wheel, engine
and transaxle system.
• When the DRIVE MODE button is
pressed and the SPORT mode is
selected, the SPORT indicator
(yellow) will illuminate.
• When the SPORT mode is activat-
ed, and the engine is turned off
and on it will change to NORMAL
mode. To turn on the SPORT
mode, press the DRIVE MODE
button again.
• If the system is activated:
- After accelerating and releasing
the accelerator pedal, the gear
and engine speed RPM may not
drop as soon as in NORMAL
mode.
- Up-shifting is delayed.
Information
In SPORT mode, the fuel efficiency
may decrease.

What to do in an emergency

Emergency towing
If towing is necessary, we recom-
mend you have it done by an autho-
rised 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 steer-
ing 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.
