wheel bolt torque Seat Arona 2018 Owner's Manual

The essentials
the wheel condition and hub mounting surfa-
c e
s.
These surfaces must be clean before fit-
ting the wheel.
Wheel bolt tightening torque
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is 120 Nm.
After changing a wheel, have the tightening
torque checked immediately with a torque
wrench that is working perfectly.
Before checking tightening torque, have any
rusty wheel bolts that are difficult to screw re-
placed and clean the wheel hub threads.
Never apply grease or oil to wheel bolts or to
the wheel hub threads. Even if the bolts have
been tightened to the prescribed torque, they
could come loose while driving. WARNING
If the wheel bolts are not properly tightened,
they c ou

ld come loose while driving and
cause an accident, serious injury and loss of
vehicle control.
● Use only wheel bolts which correspond to
the rim in question.
● Nev

er use different wheel bolts.
● Wheel bolts and threads should be clean,
free of oi
l and grease, and it should be possi-
ble to screw them easily.
● To loosen and tighten wheel bolts, only use
the wheel wrenc
h that came with the car from
the factory. ●
Loo sen the wheel

bolts only about one turn
before raising the vehicle with the jack.
● Never apply grease or oil to wheel bolts or
to the wheel hub thr
eads. Even if the bolts
have been tightened to the prescribed tor-
que, they could come loose while driving.
● Never loosen the screwed joints of wheel
rims with bo
lted ring trims.
● If wheel bolts are tightened below the pre-
scribed t
orque, the bolts and rims could come
loose while driving. If tightening torque is too
high, the wheel bolts or threads can be dam-
aged. CAUTION
When removing/fitting the wheel, the rim
ma y

hit and damage the brake disc. For this
reason, please take care and get a second
person to assist you. Tyres with compulsory direction of ro-
t
ation A directional tread pattern can be identified
b
y
the arr

ows on the sidewall that point in
the direction of rotation. Always observe the
direction of rotation indicated when fitting
the wheel to guarantee optimum properties
of this type of tyres with regard to grip,
noises, wear and aquaplaning.
If it is absolutely necessary to fit the spare
tyre* against the direction of rotation, drive with care as this means the tyre does not of-
fer optimum drivin

g properties. This is of par-
ticular importance when the road surface is
wet.
To return to directional tread tires, replace
the punctured tyre as soon as possible and
restore the obligatory direction of rotation of
all tyres.
Subsequent work ●
Alloy wheels: rep
l
ace the wheel bolt caps.
● Plate wheels: repl
ace the wheel hubcap.
● Return all tools to their proper storing loca-
tion.
● If the replaced wheel does not fit in the
spar
e wheel housing, store it safely in the
luggage compartment ›››
 page 158.
● Check the tyre pressure of the newly moun-
ted tyr
e as soon as possible.
● In vehicles fitted with a tyre pressure indi-
cator
, adjust the pressure and store it in
memory ›››
 page 287.
● Have the tightening torque of the wheel
bolts c
hecked as soon as possible with a tor-
que wrench (it should be 120 Nm). Mean-
while, drive carefully.
● Have the flat tyre replaced as quickly as
pos s

ible. 69

Wheels
Wheel bolts The design of wheel bolts is matched to the
rims. If diff
er
ent wheel rims are fitted, the
correct wheel bolts with the right length and
correctly shaped bolt heads must be used.
This ensures that wheels are fitted securely
and that the brake system functions correctly.
In certain circumstances, you should not use
wheel bolts from a different vehicle, even if it
is the same model ››› page 259. WARNING
If the wheel bolts are not tightened correctly,
the wheel c ou

ld become loose while driving.
Risk of accident.
● The wheel bolts must be clean and turn
eas
ily. Never apply grease or oil to them.
● Use only wheel bolts which belong to the
wheel.
● If the pr

escribed torque of the wheel bolts
is t
oo low, they could loosen whilst the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. CAUTION
The prescribed tightening torque for wheel
bolt s

for steel and alloy wheels is 120 Nm. Tyre monitoring indicator*

Centre console: tyre monitoring sys-
t em b
utt

on. The tyre monitoring system compares wheel
r
ev
o

lutions alongside the wheel diameter of
each wheel, with help from the ESC. If the di-
ameter of a wheel changes, the tyre monitor-
ing indicator lights up . The wheel diame-
ter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a
load.
● The wheel

s of one axle are under more
pres
sure (for example, driving with a trailer or
on steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed. Tyre pressure adjustment
After modif

ying tyre pressure or changing any
wheels, the new tyre pressure must be stored
in the Easy Connect system with the  but-
t on and the S
ET

TINGS function button
› ›
›
 page 34.
You can also press and hold down the
››› Fig. 242 button with the ignition on, until
an acoustic signal is heard.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the back of the left front door
frame). If the tyre monitor system button is
pressed down, the new tyre pressures are
confirmed.
The tyre pressure control lamp  lights up
If the tyre pressure of a wheel is much lower
than the value set by the driver, then the tyre
pressure control lamp ››› will light up.
WARNING
● When the tyr e pr

essure control lamp lights
up, reduce speed immediately and avoid any
sudden turning or braking manoeuvre. Stop
when possible, and check the tyre pressure
and status.
● The driver is responsible for maintaining
correct
tyre pressures. For this reason, tyre
pressure must be regularly checked. » 287

Drawbar loads
The maximum permitt ed dr
a
wbar load on the
ball coupling of the towing bracket must not
exceed 55 kg.
In the interest of road safety, we recommend
that you always tow approaching the maxi-
mum drawbar load. The response of the trail-
er 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 s af

ety reasons, you should not drive at
speeds above 80 km/h (50 mph) when towing
a trailer. This also applies in countries where
higher speeds are permitted.
● Never exceed the maximum trailer weights
or the drawb
ar load. If the permissible axle
load or the permissible total weight is excee-
ded, the driving characteristics of the vehicle
may change, leading to accidents, injuries
and damage to the vehicle. Wheels
Ty
r

e pressure and wheel bolts Tyre pressure
The stic
k

er with the tyre pressure values can
be found on the back of the left front door
frame. The tyre pressure values given there
are for cold tyres. Do not reduce the slightly
raised pressures of warm tyres ››› .
The pre s

sure for winter tyres is 0.2 bar higher
than that of summer tyres (2.9 psi / 20 kPa).
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 al lo
y

wheels is 120 Nm. WARNING
● Check the ty

re pressure at least once per
month. Checking the tyre pressure is very im-
portant. 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 t
oo low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. Note
We recommend that you ask your Technical
Serv ic

e for information about appropriate
wheel, tyre and snow chain size. 293
