2013 Seat Leon SC warning

181
Driving
– Select Eco mode ⇒ page 211 once in SEAT Drive Mode*.
– Take your foot off the accelerator.
The driver message Inertia will be displayed. At speeds higher
than 20 km/h (12 mph), the gearbox will automatically disengage
and the vehicle will roll freely, without the effect of the engine
brake. While the vehicle rolls, the engine runs at idling speed.
Stopping inertia mode
– Press the brake or the accelerator pedal.
To make use of the braking force and switch off the engine again,
simply press the brake pedal briefly.
Applying both the inertia mode (= prolonged section with less energy) and
the switching off using inertia (= shorter section without the need for fuel)
facilitates improved fuel consumption and emission balance.
WARNING
● If the inertia mode has been switched on, take into account, when ap-
proaching an obstacle and releasing the accelerator pedal, that the vehi-
cle will not decelerate in the usual manner: risk of accident!
● When using inertia mode while travelling down hills, the vehicle can
increase speed: risk of accident!
● If other users drive your vehicle, warn them about inertia mode.
Note
● Inertia mode is only available in eco driving mode (SEAT Drive Mode*).
● The driver message Inertia is only displayed with the current consump-
tion. In inertia mode the gear will no longer be displayed (for example: “E”
will appear in place of “E7”).
● On downhill sections with gradients above 15 %, the inertia mode will
automatically be switched off temporarily. 
Backup programme
A backup programme is in place if a fault should occur in the
control system.
If all the positions of the selector lever are shown over a light background
on the instrument panel display, there is a system fault and the automatic
gearbox will operate in with the backup programme. When the backup pro-
gramme is activated, it is possible to drive the vehicle, however, at low
speeds and within a selected range of gears. In some cases driving in re-
verse gear may not be possible .
CAUTION
If the gearbox operates with the backup programme, take the vehicle to a
specialised workshop and have the fault repaired without delay. 

certain degree of practical skill. We therefore advise you to obtain
professional assistance.
A screwdriver will be needed to carry out the manual release. Use
the flat part of the screwdriver blade ⇒ page 274.
Removing the cover from the selector lever
– Apply the handbrake  ⇒ 
to ensure that the car does not
move.
– Carefully pull the corners of the selector lever boot and fold up
the selector lever boot (inside out) by hand.
Releasing the selector lever
– Using a screwdriver, press and hold the yellow unlocking tab
sideways ⇒ Fig. 125.
– Now press the interlock button on the selector lever A
and
move the selector lever to position N.
– After carrying out the manual release, attach the selector lever
boot on the gearbox console again.
If the power supply should ever fail (discharged battery, etc.) and the vehi-
cle has to be pushed or towed, the selector lever must first be moved to po-
sition N. This is possible after operating the manual release mechanism.
WARNING
The selector lever may be moved out of position P only when the hand-
brake is firmly applied. If this does not work, secure the vehicle with the
brake pedal. On a slope the vehicle could otherwise start to move inad-
vertently after shifting the selector lever out of position P - accident risk!

Cruise control system (CCS)*
Introduction
The cruise control system (CCS) is able to maintain the set speed from 20
km/h (15 mph).
A constant speed is maintained using the engine power control or by apply-
ing the active brake ⇒ 
.
Additional information and warnings:
● Change gear ⇒ page 173.
● Accessories and technical modifications ⇒ page 272.
WARNING
Use of the cruise control could cause accidents and severe injuries if it is
not possible to drive at a constant speed maintaining the safety distance.
● Do not use the cruise control in heavy traffic, if the distance from the
vehicle in front is insufficient, on steep roads, with several bends or in
slippery circumstances (snow, ice, rain or loose gravel), or on flooded
roads.
● Never use the CCS when driving off-road or on unpaved roads.
● Always adapt your speed and the distance to the vehicles ahead in
line with visibility, weather conditions, the condition of the road and the
traffic situation.
● To avoid unexpected operation of the cruise control system, turn it off
every time you finish using it.
WARNING (Continued)
● It is dangerous to use a set speed which is too high for the prevailing
road, traffic or weather conditions.
● When travelling down hills, the CCS cannot maintain a constant
speed. The vehicle tends to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the vehicle.

Adaptive cruise control (ACC)*
Introduction
Fig. 129 Detection area
Adaptive cruise control (ACC) is an extension of vehicle cruise control (GRA)
⇒ 
.
The ACC function allows the driver to establish a cruising speed between 30
and 160 km/h (18 and 100 mph), as well as the time distance from the ve-
hicle ahead. The ACC function will adapt to the vehicle's adaptive cruise
speed at all times, maintaining a safety distance from the vehicle ahead.
The ACC function is based on a radar sensor that can measure the distance
to vehicles ahead.
If the vehicle is equipped with automatic gearbox, the ACC may brake it un-
til it stops completely if the vehicle ahead stops.
Request for driver intervention
During driving, the ACC is subject to certain limitations inherent in the sys-
tem. In other words, in certain circumstances the actual driver will have to
control speed and distance with regard to other vehicles. In this case, the instrument panel display
will tell the driver to intervene by
pressing the brake pedal, and a warning sound will go off ⇒ page 191.
Additional information and warnings:
● SEAT information system ⇒ page 73
● Easy Connect system ⇒ page 79
● Cruise control system (CCS) ⇒ page 184
● Front Assist ⇒ page 202
● Lane Assist ⇒ page 207
● Accessories, parts replacement, repairs and modifications ⇒ page 272
WARNING
The intelligent technology in the ACC cannot overcome the system's own
limitations or change the laws of physics. If used negligently or uninten-
tionally it may cause a serious accident and serious injury. The system is
not a replacement for driver awareness.
● Always adapt speed and safety distance to the vehicle ahead accord-
ing to visibility, weather, road and traffic conditions.
● Do not use the ACC in conditions of poor visibility, on steep roads,
with several bends or in slippery circumstances such as snow, ice, rain or
loose gravel or on flooded roads.
● Never use the ACC when driving off-road or on unpaved roads. The
ACC has only been designed for use on paved roads.
● The ACC does not react on approaching a stationary obstacle, such as
the end of a traffic jam or a broken-down vehicle or a vehicle stopped at
traffic lights.
● The ACC does not react during driving to people or animals or vehi-
cles changing lane or approaching in the opposite direction in the same
lane.
● If the ACC does not reduce speed enough, apply the foot brake imme-
diately. 

WARNING (Continued)
● If the vehicle continues to move following a driver intervention re-
quest, apply the foot brake.
● If the instrument panel display shows a driver intervention request,
adjust the distance yourself.
● The driver must be ready to accelerate or brake by him- or herself at
any time.
CAUTION
If you have the impression that the radar sensor is damaged, disconnect the
ACC. This will prevent possible damage. In this case have it adjusted.
● A radar sensor repair requires specialist knowledge and special tools.
SEAT recommends visiting a SEAT dealership for this.
Note
● If the ACC does not operate as described in this chapter, do not use it
until it has been checked by a specialised workshop. SEAT recommends vis-
iting a SEAT dealership for this.
● The maximum speed with the ACC switched on is limited to 160 km/h
(100 mph).
● When the ACC is switched on, strange noises may be heard during auto-
matic braking. Messages on the display, control and warning lampsFig. 130 On the instrument panel display: (A) ACC temporarily inactive, vehicle detec-
ted ahead, temporary distance adjusted. (B) ACC active, vehicle detected ahead, a tem-
