WARNING
The components of the exhaust system reach very high temperatures.
This could cause a fire.
● Always park your vehicle so that no part of the exhaust system can
come in contact with flammable materials (such as dried grass).
● Never apply additional underseal or anti-corrosion coatings to the ex-
haust pipes, catalytic converter or the heat shields on the exhaust sys-
tem.

Fault in engine management
(Electronic Power Control).Take the vehicle to a specialised
workshop as soon as possible
and have the engine checked.
Fault in catalytic converter.
You should reduce speed accord-
ingly. Drive carefully until you
reach the next specialised work-
shop. Have the engine checked
there.

Combustion fault which could
damage the catalytic convert-
er.You should reduce speed accord-
ingly. Drive carefully until you

Several warning and control lamps should light up for a few seconds when
the ignition is switched on, signalling that the function is being verified.
They will switch off after a few seconds.
CAUTION
Always pay attention to any lit control lamps and to the corresponding de-
scriptions and instructions 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.

254Practical information
If the wheel bolt is very tight, you may be able to loosen it by pushing down
on the end of the wheel brace carefully with your foot. Hold on to the vehicle
for support and take care not to slip.
Loosening wheel bolts
● Fit the wheel brace as far as it will go over the wheel bolt ⇒ Fig. 144.
● Hold the wheel brace at the end and rotate the bolt approximately one
turn anticlockwise ⇒
.
Loosening anti-theft wheel bolts
For wheels with full hubcap, the anti-theft wheel lock must be threaded into
position ⇒ Fig. 145 2
before mounting the hubcap. Otherwise it will not be
possible to mount the full hubcap.
● Take the adapter for anti-theft wheel bolts out of the vehicle tool kit.
● Insert the adapter onto the wheel bolt ⇒ Fig. 145. Push it on as far as it
will go.
● Fit the wheel brace onto the adapter as far as possible.
● Hold the wheel brace at the end and rotate the bolt approximately one
turn anticlockwise ⇒
.
Important information about wheel bolts
The wheel rims and bolts have been designed to be fitted to factory op-
tions. If different 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 some circumstances, wheel bolts from the same model vehicle should
not be used.
Wheel bolt tightening torque
The prescribed tightening torque for wheel bolts for steel and alloy wheels
is 110 Nm. Have the tightening torque of the wheel bolts checked as soon
as possible with a reliable torque wrench. If wheel bolts are rusty and it is difficult to tighten them, the threads should
be replaced and cleaned before checking the tightening torque.
Never grease or lubricate wheel bolts or the wheel hub threads. Although
they have been tightened to the prescribed torque, they could come loose
while driving.
WARNING
If the wheel bolts are not fitted correctly they could be released while
driving leading to loss of vehicle control and serious damage.
● Only use wheel bolts which correspond to the wheel rims in question.
● Never use different wheel bolts.
● The bolts and threads should be clean, free of oil and grease and easy
to thread.
● To loosen and tighten the wheel bolts, always use the wheel brace
supplied with the vehicle.
● Loosen the wheel bolts only about one turn before raising the vehicle
with the jack.
● Never grease or lubricate wheel bolts or the wheel hub threads. Al-
though they have been tightened to the prescribed torque, they could
come loose while driving.
● Never loosen the bolted joints of wheel rims with bolted ring trims.
● If the wheel bolts are not tightened to the correct torque, they may
come loose while driving, and the bolts and rims may come out. If the
tightening torque is too high, the wheel bolts and threads can be dam-
aged.

Practical information
Changing a wheel
Fig. 148 Changing a
wheel: loosen wheel
bolts with the socket at
the end of the wheel
brace
Removing the wheel
● Please observe the check list ⇒ page 253.
● Loosen the wheel bolts ⇒ page 253.
● Jacking up the vehicle ⇒ page 255.
● Using the hexagonal socket in the wheel brace ⇒ Fig. 148, unscrew the
slackened wheel bolts and place them on a clean surface.
● Take off the wheel.
How to use the spare wheel or temporary spare wheel
Check the direction of rotation of the tyre ⇒ page 218, Tyre code.
● Place the spare wheel or temporary spare wheel into position.
● Replace the wheel bolts and tighten slightly using the hexagonal socket
on the end of the wheel brace.
● To tighten the anti-theft locking wheel bolts use the corresponding
adaptor.
● Lower the car with the jack. ●
Tighten all of the wheel bolts clockwise ⇒
. Tighten the bolts in diago-
nal pairs (not in a circle).
● Put the caps, trim or full hubcap back on ⇒ page 250.
WARNING
If the wheel bolts are not treated suitably or not tightened to the correct
torque then this could lead to loss of vehicle control and to a serious ac-
cident.
● All the wheel bolts and hub threads should be clean and free of oil
and grease. The wheel bolts should be easily tightened to the correct tor-
que.
● The hexagonal socket in the wheel brace should be used for turning
wheel bolts only. Do not use it to loosen or tighten the wheel bolts.
After changing the wheel
● Clean the vehicle tools, if necessary and put them away in the luggage
compartment foam holder ⇒ page 247.
● Store the spare wheel, the temporary spare wheel or the changed wheel
securely in the luggage compartment.
● Have the tightening torque of the wheel bolts checked as soon as possi-
ble with a torque wrench ⇒ page 254.
● Have the flat tyre replaced as quickly as possible.
