5. Make sure that the vehicle jack foot stands
vertically and at a right angle beneath the
jacking point.
6. Make sure that the vehicle jack foot stands
vertically and perpendicularly beneath the
jacking point after extending the vehicle
jack.
7. Crank the vehicle up, until the vehicle jack
is with the entire surface on the ground
and the relevant wheel is maximum 1.2 in‐
ches/3 cm above ground.
Mounting a wheel
Mount one emergency wheel only, as required.
1.
Unscrew the lug bolts.
2. Remove the wheel.
3. Put the new wheel or emergency wheel on
and screw in at least two lug bolts in a
crosswise pattern until hand-tight.
If non-original light-alloy wheels of the ve‐
hicle manufacturer are mounted, the ac‐
companying lug bolts may have to be used
as well.
4. Hand-tighten the remaining lug bolts and
tighten all lug bolts well in a crosswise pat‐
tern.
5. Turn the vehicle jack crank counterclock‐
wise to retract the vehicle jack and lower
the vehicle.
6. Remove the vehicle jack and stow it se‐
curely.
After the wheel change
1. Tighten the lug bolts crosswise. The tight‐
ening torque is 101 lb ft/140 Nm.
2. Stow the nonworking wheel in the cargo
area, if necessary.
The nonworking wheel cannot be stored
under the cargo floor panel because of its
size.
3. Check tire inflation pressure at the next op‐
portunity and correct as needed.
4. Reinitialize the run-flat tires.
Reset the Tire Pressure Monitor TPM.
5. Check to make sure the lug bolts are tight
with a calibrated torque wrench.
6. Have the damaged tire replaced at the
nearest dealer’s service center or another
qualified service center or repair shop.
Emergency wheel
Concept
In the event of a flat tire, the emergency wheel
can be used in place of the wheel with the de‐
fective tire. The emergency wheel is only in‐
tended for temporary use until the defective
tire/wheel has been replaced.
General information
Mount one emergency wheel only.
Also check the tire inflation pressure of the
emergency wheel in the cargo area regularly,
and correct it as needed.
