to lock the wheels, apply the parking brake,
unless it is programmed to be in automatic
mode, and switch off the ignition.
Check for the fixed illumination of the parking
brake indicator lamps in the instrument panel.
The occupants must get out of the vehicle
and wait where they are safe.
If necessary, place a chock under the wheel
diagonally opposite the wheel to be changed.
Never go underneath a vehicle raised using a
jack; use an axle stand.
Wheel with wheel trim
When removing the wheel , first remove
the wheel trim by pulling at the valve aperture
using the wheelbrace.
When refitting the wheel , refit the wheel
trim, starting by placing its aperture in line
with the valve and then pushing it into place
all round its edge with the palm of your hand.


– If the vehicle has steel wheels, remove the wheel trim.– If the vehicle has alloy wheels, remove the central bolt cover using tool 7.– If the vehicle is so equipped, fit security bolt socket 2 to wheelbrace 5 to slacken the security
bolt.
– Slacken the other bolts using the wheelbrace 5 only.

► Place the foot of jack 6 on the ground and ensure that it is directly below the front A or rear B jacking point on the underbody, whichever
is closest to the wheel to be changed.


► Extend jack 6 until its head comes into contact with jacking point A or B; contact area A
or B on the vehicle must be properly inserted
into the central part of the head of the jack.
► Raise the vehicle until there is sufficient space between the wheel and the ground to
admit the spare (not punctured) wheel easily.
Ensure that the jack is stable. If the
ground is slippery or loose, the jack may
slip or collapse - risk of injury!
Take care to position the jack strictly at
one of the jacking points A or B under the
vehicle, ensuring that the head of the jack is
centred under the contact area of the vehicle.
Otherwise, there is a risk of damage to the
vehicle and/or of the jack collapsing - risk of
injury!
