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 cross‐
wise pattern until hand-tight.
When non-original light-alloy wheels of the
vehicle 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 counterclockwise
to retract the vehicle jack and lower the vehi‐
cle.
6. Remove the vehicle jack and stow it securely.
After the wheel change
1. Tighten the lug bolts crosswise. The tighten‐
ing torque is 101 lbs ft/140 Nm.
2. Stow the nonworking wheel in the cargo area,
if necessary.
3. Check tire inflation pressure at the next op‐
portunity and correct as needed.
4. Reinitialize the Flat Tire Monitor.
Reset the Tire Pressure Monitor again.
5. Check to make sure the lug bolts are tight
with a calibrated torque wrench.
6. Have the damaged tire replaced at the near‐
est dealer's service center or another quali‐
fied service center or repair shop.
