Wheel Changing

WARNING:

Always secure the spare wheel, or the
removed wheel, in the correct position
using the retaining bolt. Failure to do so
may cause the spare wheel to move in
the event of a sudden manoeuvre or
accident, leading to death or serious
injury.

WARNING:

Ensure that the floor panel is placed
where it cannot fall and cause injury
when it is removed from the vehicle.

WARNING:

When removing or replacing the floor
panel ensure that fingers and hands
are kept clear. Failure to do so may
result in crush injuries.

The spare wheel and jacking equipment
are stored under the trunk floor panel.

To remove the spare wheel, fully unscrew
and remove the locking ring (1). Unscrew
and remove the wing nut (2) below the
locking ring. This allows wheel retainer (3)
to be lifted and removed. The wheel can
now be lifted out.

WARNING:

Apply the Electric Parking Brake (EPB),
and engage Park in vehicles fitted with
an automatic transmission.

WARNING:

Apply the EPB and engage 1st or
reverse gear in vehicles fitted with a
manual transmission.

WARNING:

Ensure that the jack is on firm, level
ground.

WARNING:

Never place anything between the jack
and the ground, or the jack and the
vehicle.

WARNING:

Always chock the wheels using
suitable wheel chocks. Place the
chocks on both sides of the wheel,
diagonally opposite the wheel to be
changed.

WARNING:

If jacking the vehicle on a slight slope is
unavoidable, place the chocks on the
downhill side of the two opposite
wheels.

WARNING:

Take care when lifting the spare wheel,
and removing the punctured wheel.
The wheels are heavy, and can cause
injuries if not handled correctly.

WARNING:

Remove the spare wheel prior to
jacking the vehicle. To avoid
destabilising the vehicle when raised.

WARNING:

Take care when loosening the wheel
nuts. The wheel brace may slip off if not
properly attached, and the wheel nuts
may give way suddenly. Either
unexpected movement may cause an
injury.

Ensure that all passengers are in a safe
place, clear of the vehicle.

Apply the EPB and select gear position P
(Park).

Ensure that the jack is placed on firm and
level ground.

Note:

When one rear wheel is lifted off the
ground, the selection of gear position P
(Park) will not prevent the vehicle from
moving and possibly slipping off the jack.

Wheel Changing

WARNING:

Ensure that the jack is correctly
located onto the jacking point.

Observe the instructions printed on the
jack.

Use the jack only for lifting the vehicle
during wheel changing, and only use the
jack which is stored in the vehicle.

Do not start or run the engine while the
vehicle is only supported by a jack.

WARNING:

Never work beneath the vehicle, or
place any part of your body beneath the
vehicle with the jack as the only means
of support. Always use suitable vehicle
support stands which are approved for
the weight of the vehicle.

Removing the wheel

Before raising the vehicle slacken, but do
not remove, the wheel nuts.

There are four jacking points, two each
side of the vehicle on the underside of the
floor. These provide positive location for
the jack.

To locate the jacking point, feel along the
sill panel to the cut-away portion and then
fit the jack to the body, as shown, not to
the sill panel.

Caution:

Ensure before raising the vehicle that
the jack is correctly positioned to avoid
any damage to the vehicle sills or sill
panels. Use only the correct jacking
points, never use bumpers or any other
part of the body to lift the vehicle.

WARNING:

Do not attempt to lift the vehicle unless
the jack head is fully engaged in the
jacking point.

WARNING:

Ensure that the EPB is applied.

Wheel Changing

212

Place the jack squarely beneath the
appropriate jacking point. Ensure that the
jack head is fully engaged. Carefully raise
the vehicle by turning the jack handle and
continue jacking until the tire just clears
the ground. Minimum tire lift gives
maximum vehicle stability.

Remove the wheel nuts and the wheel.

Centre badge

When changing the alloy road wheels,
transfer the centre badge to the
replacement wheel. Using the plastic
tipped end of the wheel nut wrench
handle, push the centre badge from its
housing.

Push the centre badge into the
replacement wheel.

Fitting the spare wheel

Fit the spare wheel and loosely secure
with the wheel nuts.

Using the wheel nut wrench, lightly
tighten the wheel nuts alternately using
the sequence shown in the illustration.

Lower the jack and tighten the wheel nuts
alternately, DO NOT OVER TIGHTEN.

At the earliest opportunity have the wheel
nuts tightened with a torque wrench to
125 Nm (92 lbf.ft).

This torque must not be exceeded.

Stowing the equipment

Stow the replaced road wheel in the trunk.

Check that the wing nut is unscrewed fully
so that it is as close as possible to the
handle of the wheel retainer. This is to
ensure that the wheel retainer can be
fitted correctly.

Locate the wheel retainer into its mating
thread in the trunk floor, tighten it fully,
then tighten the wing nut clockwise to
secure the wheel.

Stow the jacking equipment.

Close the trunk floor panel.

WARNING:

When a temporary spare wheel is
fitted, drive with caution and replace
with the specified wheel and tire as
soon as possible.

Note:

If your vehicle is fitted with a TPMS, it may
take a few minutes for the system to
recognise the replaced wheel. Please see
page 253 for further information on the
TPMS.
