2014 Seat Mii overheating

Driving
Driving down hills
The steeper the gradient, the lower the gear
you will need to select. The lowest gears in-
crease the engine braking work. Never go
down hills with the selector lever in neutral
N .
● You shou
ld reduce speed accordingly.
● Place the lever in the position D to the left
on the Tiptronic shift gate M
››› page 96.
● Gently pull the selector lever back – to
change down a gear.
Starting when going up a slope
The steeper the gradient, the lower the gear
you will need.
When stopping on a slope with a gear range
engaged, the vehicle must be prevented from
rolling backwards by always pressing the
brake pedal or pulling the handbrake lever
up. When starting, release the brake pedal or
the handbrake ››› .
Kick-down
The kickdown system provides maximum ac-
celeration when the gear selector lever is in
the position D
, or in the Tiptronic position M
.
When the accelerator pedal is pressed right
down, the automatic gearbox will shift down
to a lower gear, depending on road speed
and engine speed. This takes advantage of the maximum acceleration of the vehicle
››› .
When the accelerator is pressed to the floor,
the automatic gearbox shifts to the next gear
only after the engine reaches the specified
maximum engine speed. WARNING
Rapid acceleration can cause loss of traction
and skidding, especially on slippery ground.
This could cause loss of control of the vehicle
resulting in an accident and serious injury.
● Always adapt your driving style to suit the
flow of traffic.
● Only use the kick-down function or rapid
acceleration if visibility, weather, road and
traffic conditions so permit.
● Never put other road users in danger by ac-
celerating or with your driving style. CAUTION
If you stop on a hill with a gear range engag-
ed, do not try to prevent the vehicle from roll-
ing back by pressing on the accelerator. Oth-
erwise, the automatic gearbox may overheat
causing damage. Automatic gearbox malfunction
Back-up programme
When automatic gearbox warning and control
lamps light up on the instrument panel, there
may be a system malfunction
››› page 93. In
the event of some faults the automatic gear-
box functions using a backup programme.
When the programme is activated, it is possi-
ble to drive the vehicle, however, at low
speeds and within a selected range of gears.
With the manual gearbox, in some cases it is
not possible to drive with all the gears .
In all cases the automatic gearbox must be
checked at a specialised workshop.
Automatic gearbox overheating
The automatic gearbox can overheat with a
prolonged start up, or when stopping and
starting continuously. This overheating is dis-
played with a warning lamp  in the instru-
ment panel. Additionally, an audible warning
can be heard. Stop and let the gearbox cool
››› .
The vehicle moves forward or back despite
having selected a gear range
When the vehicle does not move in the re-
quired direction, the system may not have
the gear range correctly engaged. Press the
brake pedal and engage the gear range
again. If the vehicle still does not move in the »

Several warning and control lamps light up
for a few seconds when the ignition is switch-

verified. They will switch off after a few sec-
onds.
CAUTION
Always pay attention to any lit control lamps
and to the corresponding descriptions and in-
structions to avoid damage to the vehicle. Note
While the control lamps  or
 maintain lit
up, the engine will present faults, a higher consumption of fuel and a loss of engine
power.
Catalytic converter
The catalytic converter permits the subse-
quent treatment of the exhaust gases thus
reducing contaminating gas emissions. To
ensure a longer working life for the exhaust
system and catalytic converter in a petrol en-
gine:
● Always use unleaded petrol.
● Never run the fuel tank completely dry.
● Do not top up with too much engine oil
››› page 146 .
● Do not t

ow-start the vehicle; use the starter
cables ››› page 181.
If

you should notice misfiring, uneven run-
ning or loss of power when the car is moving,
reduce speed immediately. Have the car in-
spected by a specialised workshop. If this
happens, unburnt fuel can enter the exhaust
system and escape into the atmosphere. The
catalytic converter can also be damaged by
overheating. For the sake of the environment
Even when the emission control system is
working perfectly, there may be a smell of
sulphur under certain conditions. This de- pends on the sulphur content of the fuel
used.
Driving abroad
In some countries, certain safety regulations
and requirements are in force relating to ex-
haust gas emissions, which differ from the
technical characteristics of the vehicle. Be-
fore travelling abroad, SEAT recommends you
consult a technical service about the legal re-
quirements and the following points:
●
Does the vehicle need technical modifica-
tions for driving abroad, for example, adjust-
ment of the headlamps?
● Does the vehicle have all the tools, diag-
nostics equipment and spare parts required
for inspections and repairs?
● Are there any SEAT dealers in the destina-
tion country?
● For petrol vehicles: Is unleaded petrol avail-
able at the right octane rating?
● For diesel engines: is diesel fuel available
with a low sulphur content?
● Are a suitable engine oil ( ››› page 146) and
other engine fluids complying with SEAT
specifications available in the destination
country?

Operation
the driver control the vehicle due to the loss
of adherence with the road surface prevent-
ing braking and steering. If the vehicle is
driven through series of bends at high
speed, the ESC* will not always be as effec-
tive: the vehicle reaction to aggressive driv-
ing is not the same as at reduced speeds.
Adjust your speed and driving style to suit
visibility, and weather, road and traffic condi-
tions. ESC* cannot push the limits of the laws
of physics; improve the transmission availa-
ble or maintain the vehicle on the road if a
lack of driver attention creates an inevitable
situation. Otherwise, ESC* assists in main-
taining vehicle control in extreme situations
and uses the movements of the steering
made by the driver to maintain the vehicle
moving in the desired direction. If the vehicle
is driven at such a speed that it will leave the
road before ESC* can intervene then the sys-
tem cannot provide assistance.
The ABS, BAS, ASR and EDL systems are in-
corporated into the ESC*. The ESC* is always
on 1)
.
Anti-lock brake system (ABS)
ABS can prevent the wheels from locking dur-
ing braking until just before the vehicle stops
thus helping the driver to steer the vehicle
and maintain control. This means that, even during full braking, the risk of skidding is re-
duced:
● Press and hold the brake pedal fully. Do not
remove your foot from the brake pedal or re-
duce braking force!
● Do not “pump” the brake pedal, or reduce
braking force!
● Maintain vehicle direction when braking
fully.
● When the brake pedal is released or when
the brake force is reduced, ABS is turned off.
ABS control can be observed by vibration of
the brake pedal and noise. You should never
e xpect
the ABS to reduce the braking dis-
tance under
any circumstances. This distance
will increase when driving on gravel, recent
snow or on icy or slippery ground.
Brake assist system (BAS)
The brake assist system may reduce the re-
quired braking distance. The brake assist
system boosts the braking force if you press
the brake pedal quickly in an emergency. As
a result, the braking pressure increases rap-
idly, the braking force is multiplied and the
braking distance is reduced. This enables the
ABS to be activated more quickly and effec-
tively. ¡Do not lift your foot off the brake pedal!
When the br
ake pedal is released or when
the brake force is reduced, braking assist au-
tomatically turns off the brake servo.
Traction control system (ASR) or Traction
Control (TC)
In the event of wheelspin, the traction control
system ASR or TC reduces the engine torque
to match the amount of grip available. The
ASR or TC makes some situations easier, for
example, when starting, accelerating or go-
ing uphill, even in unfavourable road condi-
tions.
Electronic differential lock system (EDL)
EDL is available when driving in straight lines
under normal conditions. When the EDL de-
tects wheelspin, it brakes the spinning wheel
and directs the power to the other one. To
prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The EDL
will switch on again automatically when the
brake has cooled down. WARNING
Driving at high speed on icy, slippery or wet
ground can result in loss of vehicle control 1)
Depending on the version.

Checking and refilling levels
The vehicle is only prepared for refuelling
with Compressed Natural Gas (CNG) ››› . Re-
fuelling with another type of natural gas is
not allowed, e.g. Liquefied Nature Gas (LNG)
or hydromethane.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel
tank cap, next to the petrol filler mouth.
● Unlock the vehicle with the key or with the
central locking button  situated on the driv-
er door ›
›
› page 48.
● Press on the rear area of the flap and open
it.
Refuelling
Problem:
If the ambient temperature is very
high, the natural gas pump protection
against overheating disconnects this auto-
matically.
● Remove the plug from the gas filler mouth
››› Fig. 104
1 .
● Connect the pump filling nozzle to the gas
filler mouth.
● The fuel tank will be full when the pump
c ompr

essor automatically cuts the supply.
● If you wish to finish refuelling in advance,
press the button on the pump to stop the
flow. Closing the fuel tank cap
●
Check that the gas filler mouth retainer 2 is not trapped with the filler nozzle. If neces-
sary, place it in the filler mouth again.
●
Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it
click into place. WARNING
Natural gas is a highly explosive, easily flam-
mable substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries.
● Before refuelling with natural gas, the fill-
ing mouth must be correctly engaged. If you
can smell gas, stop refuelling immediately. WARNING
The vehicle is not prepared to use liquefied
natural gas (LNG) and this fuel must not be
added under any circumstances. Liquefied
natural gas can cause the natural gas tank to
explode, resulting in serious injury. Note
● The filling nozzles of natural gas pumps
can differ in the way they are operated. If you
are unacquainted with the pump, it is advisa-
ble that a member of staff of the service sta-
tion performs the refuelling operation. ●
Noises heard when refuelling are normal
and do not indicate the presence of a fault in
the system.
● The vehicle natural gas system is prepared
both for refuelling with a small compressor
(slow refuel) and a large compressor (fast re-
fuel) in natural gas service stations. Bonnet
Working in the engine compartment Before working in the engine compartment,
make sure that the vehicle is parked on hori-
zontal and firm ground.
The engine compartment of the vehicle is a
hazardous area. Never work on the engine or
in the engine compartment if you are not fa-
miliar with the operations to be carried out,
the applicable safety standards and especial-
ly if you do not have the necessary instru-
ments, liquids and tools
››› ! If required,
have any work carried out by a specialised
workshop. Negligent work can cause serious
injury. WARNING
If the vehicle moves unexpectedly, this could
cause serious injury. » 143
