2014 Seat Mii ECU

Operation
●
While driving, always keep object compart-
ments closed.
● Remove all objects from the front passen-
ger seat when it is folded down. When the
seat backrest is folded down, it presses on
small and light objects and these are detec-
ted by the weight sensor on the seat; this
sends false information to the airbag control
unit.
● While the backrest of the front passenger
seat is folded, the frontal airbag must remain
disconnected and the PASSENGER AIRBAG
OFF  light on.
● Ob
jects secured in the vehicle should never
be placed in such a way as to make passen-
gers sit in an incorrect position.
● If secured objects occupy a seat, this seat
should not be occupied or used by anyone. WARNING
The driving behaviour and braking ability
change when transporting heavy and large
objects.
● Adjust your speed and driving style to visi-
bility, road, traffic and weather conditions.
● Accelerate gently and carefully.
● Avoid sudden braking and manoeuvres.
● Brake early. Transporting a load
Secure all objects in the vehicle
● Distribute the load throughout the vehicle
and on the roof as uniformly as possible.
● Transport heavy objects as far forward as
possible in the luggage compartment and
lock the seat backs in the vertical position.
● Check the headlight adjustment
››› page 55.
● Use the s

uitable tyre pressure according to
the load being transported. Read the tire in-
flation information label ›››
page 158. CAUTION
Objects on the shelf could chafe against the
wires of the heating element in the heated
rear window and cause damage. Note
Please refer to the notes on loading the roof
carrier ››› page 77. Driving with the rear lid open
Driving with the rear lid open creates an addi-
tional risk. Secure all objects and secure the
rear lid correctly and take all measures possi-
ble to reduce toxic gases from entering the
vehicle. WARNING
Driving with the rear lid unlocked or open
could cause serious injuries.
● Always drive with the rear lid closed.
● Secure all objects in the vehicle. Loose
items could fall out of the vehicle and injure
other road users or damage other vehicles.
● Drive particularly carefully and think
ahead.
● Avoid sudden manoeuvres and braking giv-
en that this could cause an uncontrolled
movement of the open rear lid.
● When transporting objects that protrude
out of the luggage compartment, indicate
them suitably. Observe legal requirements.
● If objects must project out of the luggage
compartment, the rear lid must never be used
to “secure” or “attach” objects.
● If a baggage rack is fitted on the rear lid, it
should be removed before travelling with the
rear lid open. WARNING
Toxic gases may enter the vehicle interior
when the rear lid is open. This could cause
loss of consciousness, carbon monoxide poi-
soning, serious injury and accidents.
● To avoid toxic gases entering the vehicle al-
ways drive with the rear lid closed. 66

Transport and practical equipment
●
In exceptional circumstances, if you must
drive with the rear lid open, observe the fol-
lowing to reduce the entry of toxic gases
inside the vehicle:
–Close all windows.
– Disable air recirculation mode.
– Open all of the air outlets on the instru-
ment panel.
– Switch on the blower to maximum. CAUTION
An open boot hatch changes the length and
height of the vehicle. Driving a loaded vehicle
For the best handling when driving a loaded
vehicle, note the following:
● Secure all objects ››› page 66 .
● Ac
celerate gently and carefully.
● Avoid sudden braking and manoeuvres.
● Brake early.
● If necessary, read the instructions for driv-
ing with a roof carrier system ››› page 77. WARNING
A sliding load could considerably affect the
stability and safety of the vehicle resulting in
an accident with serious consequences. ●
Secure loads correctly so they do not move.
● When transporting heavy objects, use suit-
able ropes or straps.
● Lock the seat backs in vertical position. Practical equipment
Introduction Storage compartments must only be used to
store light or small objects.
WARNING
In the event of sudden braking movements or
turns, loose objects may be thrown around
the vehicle interior. This could cause serious
injuries to passengers and cause the driver to
lose control of the vehicle.
● Do not transport animals or place hard,
heavy or sharp objects inside the vehicle in:
open storage compartments, dash panel, rear
shelf, items of clothing or bags.
● While driving, always keep object compart-
ments closed. WARNING
Objects falling into the driver's footwell could
prevent use of the pedals. This could lead the
driver to lose control of the vehicle, increas-
ing the risk of a serious accident. ●
Make sure the pedals can be used at all
times, with no objects rolling underneath
them.
● The floor mat should always be secured to
the floor.
● Never place other mats or rugs on top of
the original mat supplied by the factory.
● Make sure that no objects can fall into the
driver's footwell while the vehicle is in mo-
tion. CAUTION
● Objects on the shelf could chafe against
the wires of the heating element in the heat-
ed rear window and cause damage.
● Do not keep temperature-sensitive objects,
food or medicines inside the vehicle. Heat
and cold could damage them or render them
useless.
● Light-transparent objects placed inside the
vehicle, such as lenses, magnifying glasses
or transparent suction caps on the windows,
may concentrate the sun's rays and cause
damage to the vehicle. Note
The ventilating slits between the heated rear
window and the rear shelf must not be cov-
ered so that used air can escape from the ve-
hicle. 67

Introduction Always transport heavy loads in the luggage
compartment and place the seat backs in a
vertical position. Never overload the vehicle.
Both the carrying capacity as well as the dis-
tribution of the load in the vehicle have ef-
fects on the driving behaviour and braking
ability
››› .
WARNING
When the vehicle is not in use or being
watched, always lock the doors and the rear
lid to reduce the risk of serious injury or
death.
● Do not leave children unwatched, especial-
ly when the boot is open. Children could
climb into the luggage compartment, close
the rear lid from inside and be unable to es-
cape themselves. This could lead to serious
injury or death.
● Never allow children to play in or around
the vehicle.
● Never transport people in the luggage com-
partment. WARNING

through the vehicle interior. To reduce the
risks, please note the following:
●
Secure all objects in the vehicle. Always
place equipment and heavy objects in the
boot.
● Always secure objects to the fastening
rings with suitable rope or straps to prevent
them from being thrown around the interior
and moving to the airbag deployment area in
the event of sudden movements or accidents.
● While driving, always keep object compart-
ments closed.
● Do not place hard, heavy or sharp objects
inside the vehicle interior, in open storage
compartments, the rear shelf or on the dash
panel.
● Remove hard, heavy and sharp objects from
clothes and pockets inside the vehicle and
store securely. WARNING
The transport of heavy object changes vehi-
cle handling and increases braking distance.
Heavy loads that have not been stored or se-
cured correctly could cause loss of control
and result in serious injury.
● Vehicle handling changes when transport-
ing heavy objects due to a change in the cen-
tre of gravity.
● Distribute the load as uniformly and as low
down on the vehicle as possible. ●
Store heavy objects in the luggage com-
partment as far from the rear axle as possi-
ble. CAUTION
Hard objects on the rear shelf could chafe
against the wires of the heating element in
the heated rear window and cause damage. Note

Transport and practical equipment
WARNING
If unsuitable or damaged belts or retaining
straps are used, they may break in the event
of braking or an accident. Objects could then
be launched across the passenger compart-
ment and cause serious or fatal injuries.
● It is important to always use belts or retain-
ing straps that are suitable and in a good
condition.
● Belts and retaining straps should be se-
curely fastened to the fastening rings.
● Objects in the luggage compartment that
are unsecured could move suddenly and mod-
ify the handling of the vehicle.
● Small light objects should also be fixed in
place.
● The maximum tensile load of the fastening
ring for securing objects should never be ex-
ceeded.
● A child seat should never be secured with
the fastening rings. Note
● The maximum tensile load that the fasten-
ing rings can support is 3.5 kN.
● Belts and securing systems for the appro-
priate load can be obtained from specialised
dealerships. SEAT recommends visiting a
SEAT dealership for this. Retaining hooks
Fig. 73
In the luggage compartment: retain-
ing hooks There may be hooks in the upper left and
right part of the luggage compartment.
WARNING
Never use these hooks to secure objects. In
case of sudden braking or an accident, they
could rupture. CAUTION
The hooks can support a maximum of 2.5 kg
each. Roof carrier system
Introduction The vehicle roof has been designed to opti-
mise aerodynamics. For this reason, conven-
tional roof carrier systems cannot be secured
to the water drains.
Given that the water drains have been incor-
porated into the roof for aerodynamic rea-
sons, only the SEAT approved basic supports
and roof carrier systems can be used.
When the roof carrier system should be
removed:
●
When they are not used.
● When the vehicle is being washed in a car
wash.
● When the vehicle height exceeds the maxi-
mum height, for example, in some garages. WARNING
The risk of an accident is increased by trans-
porting heavy or bulky loads on the roof,
which affects the car's handling by shifting
the centre of gravity and increasing suscepti-
bility to cross winds.
● Always secure loads correctly with suitable
and undamaged attachment rope or straps.
● Large, heavy, wide and flat loads negatively
affect the vehicle aerodynamics, centre of
gravity and handling. » 77Technical specifications
