correct.

X
it away.

Tighten the wheel bolts evenly in a cross-
X
wise pattern in the sequence indica-
ted (1 to 5). The tightening torque is
130 Nm.
G Risk of accident
Have the tightening torque checked imme-
diately after a wheel is changed. The wheels
could work loose if they are not tightened
to a torque of 130 Nm.
Turn the jack back to its initial position and
X
store it and the rest of the vehicle tool kit
in the boot.
Push the tab of the jacking socket cap
X
under the top edge of the hole.
Push on the cap evenly until it snaps into
X
place.

Make sure that the lugs do not break off
and that the plastic retainer strap is not
trapped.
Pack the faulty wheel in the protective film

included with the collapsible emergency
spare wheel* and transport the wheel in
the boot.

When you are driving with the collapsible
emergency spare wheel* fitted, the tyre
pressure loss warning system or the elec-
tronic Run Flat Indicator* cannot function
reliably.
Stowing a used collapsible emergency
spare wheel*
If you wish to stow a used collapsible emer-
gency spare wheel* in the vehicle, you must
follow the steps below, otherwise you will not
be able to stow it. We recommend that this
work is carried out at a specialist workshop.
!
Only place the collapsible emergency
spare wheel* in the vehicle when it is dry.
Otherwise, moisture may remain in the
boot.
Unscrew the valve cap from the valve.

Remove the valve extractor from the vehi-
X
cle tool kit.

X
release the air.
