ground and the relevant wheel is maxi-
mum 1.2 inches/3 cm above ground.
Mounting a wheel
Mount one emergency wheel only, as re-
quired.
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
vehicle manufacturer are mounted, the
accompanying lug bolts may have to be
used as well.
4. Hand-tighten the remaining lug bolts
and tighten all lug bolts well in a cross-
wise pattern.
5. Turn the vehicle jack crank counter-
clockwise 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
tightening torque is 101 lbs 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
opportunity and correct as needed.
4. Reinitialize the Flat Tire Monitor.
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 an-
other 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 defective tire. The emergency
wheel is only intended for temporary use
until the defective tire/wheel has been re-
placed.
General information
Mount one emergency wheel only.
Also check the tire inflation pressure of the
emergency wheel in the cargo area regu-
larly, and correct it as needed.
Safety information
Warning
The emergency wheel has particular di-
mensions. When driving with an emer-
gency wheel, changed driving properties
may occur, for instance reduced lane sta-
bility when braking, longer braking dis-
tance, and changed self-steering proper-
ties in the limit area. There is a risk of
accident. Drive moderately and do not ex-
ceed a speed of 50 mph/80 km/h.
Overview
The emergency wheel is housed in a well on
the underbody of the vehicle. The screw
connection of the emergency wheel is under
the cargo floor panel, on the floor of the
storage compartment for the onboard vehi-
cle tool kit.
The wheel change tools are under the cargo
floor panel.
