Driver assistance systems
Tyre monitoring indicator
Fig. 102 Glove compart-
ment: tyre control switch
The tyre monitor indicator compares wheel revolutions and, with this infor-
mation, the tread of each wheel using the ABS sensors. If the tread of one or
more wheels is changed, the tyre monitoring indicator will indicate as such
on the instrument panel.
Wheel tread change
The wheel tread changes when:
● Tyre pressure is manually changed
● Tyre pressure is insufficient
● Tyre structure is damaged
● The vehicle is unbalanced because of a load
● The wheels on an axle are subject to a heavier load (e.g. when towing a
heavy load)
● The vehicle is fitted with snow chains
● The temporary spare wheel is fitted
● The wheel on one axle is changed There may be a delay in the reaction of the tyre monitoring indicator
 or it
may not indicate anything under certain circumstances (e.g. sporty driving,
snow-covered or unpaved roads, or when driving with snow chains).
Calibrating the tyre monitoring indicator
After changing the tyre pressure or replacing one or more wheels, the tyre
monitoring indicator must be recalibrated. Do the same, for example, when
the front and rear wheels are swapped.
● Switch the ignition on.
● Store the new tyre pressure in the Easy Connect system with the button

and the function button Setup ⇒ page 80 or using the switch located in
the glove compartment* ⇒ Fig. 102.
When driving, the system self-calibrates the tyre pressure provided by the
driver and the wheels fitted. After a long journey with varied speeds the pro-
grammed values are collected and monitored.
With the wheels under very heavy loads, the tyre pressure must be in-
creased to the total recommended tyre pressure before the calibration
⇒ page 266.
Note
● The tyre monitoring indicator does not function when there is a fault in
the ESC or ABS ⇒ page 183.
● An erroneous indication may be given when snow chains are in use be-
cause the chains increase the tread of the wheel. 

178Driver assistance systems
Parking aid
General information
Various systems are available to help you when parking or manoeuvring in
tight spaces, depending on the equipment fitted on your vehicle.
The rear parking aid is an audible assistant that warns about obstacles lo-
cated behind the vehicle ⇒ page 179.
During parking, the plus parking aid assists you visually and audibly about
obstacles detected in front and behind the vehicle ⇒ page 179.
WARNING
● Always pay attention (also when looking straight ahead) to traffic and
the vehicle surroundings. The assistance systems are not a replacement
for driver awareness. When inserting or removing the vehicle from a park-
ing space, or when performing similar manoeuvres the driver always as-
sumes the responsibility.
● Take into account that the system is not always in conditions to rec-
ognise or represent certain surfaces, such as dress fabric: Risk of causing
an accident!
● The sensors and cameras have blind spots, making the detection of
people and objects impossible. Pay special attention to children and ani-
mals: Risk of causing an accident!
● Always keep visual control of the vehicle surroundings: use the rear
vision mirrors for additional help.
CAUTION
● Under certain circumstances, the system does not detect or display cer-
tain objects:
–Objects such as snow chains, trailer draw bars, bars or fences
– Objects that are located above the sensors, such as protrusions in a
wall.
– Objects with certain surfaces or structures, such as wire mesh fences
or powder snow.
● When the vehicle approaches a low obstacle, it could disappear from
the angle of measurement. In this case, take into account that the system
will no longer warn about this obstacle.
● The knocks or damage on the radiator grille, bumper, wheel arch and ve-
hicle underbody can adjust the orientation of the sensors. This can affect
the parking aid function. Have the function checked by a specialised work-
shop.
Note
● In certain situations, the system can give a warning even though there is
no obstacle in the detected area, e.g:
–for roads with certain surfaces, or with long grass
– for external ultrasound sources, such as cleaning vehicles
– In downpours, intense snow or dense exhaust gases
● In order to familiarise yourself with the system, it is advised that you
practice parking in an area or car park that is free from traffic. There must be
good weather and light conditions.
● The volume and tone of the warnings can be modified, in addition to the
indications ⇒ page 181.
● In vehicles without a driver information system, these parameters can be
modified in a SEAT Official Service or in a specialised workshop.
● Please observe information on towing a trailer ⇒  page 182.

Wheels and tyres
For the sake of the environment
Summer tyres should be fitted again as soon as possible; they give better
handling on roads which are free of snow and ice. Summer tyres perform
with less rolling noise, tyre wear and – most important – reduce fuel con-
sumption. 
Snow chains
Snow chains will improve vehicle handling on snow-covered
roads.
– Snow chains can be used on the front wheels only.
– Check that the snow chains are correctly seated after driving for
a few yards. Always take the manufacturer assembly instruc-
tions into account.
– Keep your speed below 50 km/h (30 mph).
– If there is a danger of being trapped despite having mounted
the chains, it is best to disable the driving wheels (ASR) in the
ESC ⇒ page 184, Switching on/off the ESC and ASR.
Snow chains will improve braking ability as well as traction in winter condi-
tions.
For technical reasons snow chains may only be used with the following
wheel rim/tyre combination.
195/65 R15Chains with links of maximum 15 mm205/55 R16Chains with links of maximum 15 mm225/45 R17Chains with links of maximum 9 mm225/40 R18Chains with links of maximum 9 mm
Only use snow chains with fine-pitch links. The links must not protrude
more than 13.5 mm from the tyres (including tensioner).
Remove wheel covers and trim rings before fitting snow chains.
Remove the chains when roads are free of snow. Otherwise they will impair
handling, damage the tyres and wear out very quickly. 

Emergencies
– Take out the temporary spare wheel.
Chains
For technical reasons, snow chains must not be used on the temporary
spare wheel.
If you have a puncture on one of the front wheels when using snow chains,
fit the temporary spare wheel in place of one of the rear wheels. Fit the snow
chains on the rear wheel that you have removed and replace the punctured
front wheel with this wheel.
WARNING
● After fitting the temporary spare wheel, check the tyre pressures as
soon as possible. Failure to do so may cause an accident. The tyre pres-
sures are listed on the inside of the fuel tank flap.
● Do not drive at over 80 km/h (50 mph) when the temporary spare
wheel is fitted on the vehicle: risk of accident!
● Avoid heavy acceleration, hard braking and fast cornering: risk of ac-
cident!
● Never use more than one temporary spare wheel at the same time,
risk of accident.
● No other type of tyre (normal summer or winter tyre) may be fitted on
the compact temporary spare wheel rim.
 Jump starting
Jump leads
The jump lead must have a sufficient wire cross section.
If the engine fails to start because of a discharged battery, the battery can
be connected to the battery of another vehicle to start the engine.
Jump leads
Jump leads must comply with standard DIN 72553 (see cable manufactur-
er's instructions). The wire cross section must be at least 25 mm 2
for petrol
engines and at least 35 mm 2
for diesel engines.
Note
● The vehicles must not touch each other, otherwise electricity could flow
as soon as the positive terminals are connected.
● The discharged battery must be properly connected to the on-board net-
work. 

266Technical specifications
Drawbar loads
The maximum permitted drawbar load on the ball joint of the towing bracket
must not exceed 80 kg.
In the interest of road safety, we recommend that you always tow approach-
ing the maximum drawbar load. The response of the trailer on the road will
be poor if the drawbar load is too small.
If the maximum permissible drawbar load cannot be met (e.g. with small,
empty and light-weight single axle trailers or tandem axle trailers with a
wheelbase of less than 1 metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar load.
WARNING
● For safety reasons, do not exceed the 80 km/h (50 mph) limit. This is
also valid in countries where higher speeds are permitted.
● Never exceed the maximum trailer weights or the drawbar load. If the
permissible axle load or the permissible total weight is exceeded, the
driving characteristics of the vehicle may change, leading to accidents,
injuries and damage to the vehicle.

Wheels
Tyre pressure, snow chains, wheel bolts
Tyre pressures
The sticker with the tyre pressure values can be found on the inside of the
fuel tank flap. The tyre pressure values given there are for cold tyres. The
slightly raised pressures of warm tyres must not be reduced. ⇒ 
Snow chains
Snow chains may be fitted only to the front wheels, and only for the follow-
ing tyres:
175/70R14
185/60R15Chains with links not exceeding 15 mm (including the chain
closure)
215/45R16Chains with links not exceeding 9 mm (including the chain
closure)
215/40R17Chains with links not exceeding 7 mm (including the chain
closure)
Wheel bolts
After the wheels have been changed, the tightening torque of the wheel
bolts should be checked as soon as possible with a torque wrench ⇒ 
.
The tightening torque for steel and alloy wheels is 120 Nm.
WARNING
● Check the tyre pressure at least once per month. Checking the tyre
pressure is very important. If the tyre pressure is too high or too low,
there is an increased danger of accidents, particularly at high speeds.
● If the tightening torque of the wheel bolts is too low, they could loos-
en while the vehicle is in motion. Risk of accident! If the tightening tor-
que is too high, the wheel bolts and threads can be damaged.
Note
We recommend that you ask your Technical Service for information about
appropriate wheel, tyre and snow chain size. 
