Driving your vehicle
Multi-Collision Brake (MCB)
Multi-Collision Brake controls the brake
automatically in the event of an accident
where the air bag deploys to reduce the
risk of additional accidents that may
occur.
System operation
[ From the time the air bag deploys
Multi-Collision Brake monitors the
depression intensity of the brake
pedal and accelerator pedal for a short
period. The system operates when the
following conditions are met:
- The vehicle speed is under 112 mph
(180 km/h) at the time of collision.
- The brake pedal and accelerator
pedal is hardly depressed.
[ When the driver steps on the brake
pedal over a certain level whilst
Multi-Collision Brake is active, the
braking power takes priority over
automatic braking by Multi-Collision
Brake system. However, if the driver
takes his/her foot off the brake pedal,
automatic braking by Multi-Collision
Brake system will maintain automatic
braking.
System off
Multi-Collision Brake is cancelled in the
following situations:
- The accelerator pedal is depressed
over a certain level.
- The vehicle stops.
- There is malfunction of ESC (Electronic
Stability Control) or system cannot
operate normally.
- Ten seconds have passed since
the brake has been controlled
automatically by Multi-Collision Brake
system.
WARNING
[ Multi-Collision Brake decreases
the vehicle speed after a collision,
but it does not prevent the second
collision. You may drive away from
the collision spot to avoid other
dangerous situations by depressing
the accelerator pedal.
[ After the vehicle is stopped by Multi-
Collision Brake, the system stops
controlling the brakes. Depending
on the situation, the driver should
depress the brake or the accelerator
pedal to prevent further accidents.

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 lever into the 1st
gear (for Manual transmission vehicle)
or N (Neutral) position (for Automatic
transmission/Dual clutch transmission
vehicle), then apply the parking brake,
and place the ignition switch in the
LOCK/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 we recommend that
you call a HYUNDAI authorised repairer
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 tyre goes flat whilst you are driving,
apply the brakes gently and keep the
vehicle pointed straight ahead whilst 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.

Driving your vehicle
Your vehicle may be equipped with
the ISG system, which reduces fuel
consumption by stopping and restarting
the engine automatically.
The engine starts automatically as soon
as the starting conditions are met.
NOTICE
When the engine automatically starts
by the ISG system, some warning lights
(ABS, ESC, ESC OFF, EPS or Parking
brake warning light) may turn on for a
few seconds. This happens because of
low battery voltage. It does not mean
the system is malfunctioning.
Activating the ISG
Prerequisite for activation
The ISG system operates in the following
situations.
[ The driver’s seatbelt is fastened
[ The driver’s door and bonnet are
closed
[ The brake vacuum pressure is
adequate
[ The battery sensor is activated and the
battery is sufficiently charged
[ Outside temperature is not too low or
too high
[ The vehicle is driven over a constant
speed and stops
[ The climate control system satisfies
the conditions
[ The vehicle is sufficiently warmed up
[ The incline is gradual
[ The steering wheel is turned less than
180 degrees and then the vehicle
stops
Deactivating the ISG
OBC3N061014AU
If you want to deactivate the ISG system,
press the ISG OFF button.
The light on the ISG OFF button will
illuminate.
If you press the ISG OFF button again,
the system will be activated and the light
on the ISG OFF button will turn off.

NOTICE
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating, possible damage
to the transmission, and tyre damage.
See “Towing” in chapter 8.
Smooth cornering
Avoid braking or gear changing in
corners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration.
Driving at night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:

Driving in the rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:
