Pull the jack out of the jack support
tube.1 - 5 Wheel bolts
Tighten the five wheel bolts evenly,
following the diagonal sequence
illustrated (1 to 5), until all bolts
are tight. Observe a tightening torque
of 96 lb-ft (130 Nm).
Warning!G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
iThe flat tire may be transported in the trunk
when the retractable hardtop is raised. If avail-
able, use a protective sheet on the spare wheel.
Vehicles with TPMS or Advanced TPMS*:
Do not activate the tire inflation pressure moni-
tor until a full size wheel/tire with functioning
sensor has been placed back into service on the
vehicle.
Warning!G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 lb-ft (130 Nm).

TPMS* (Canada vehicles) (
page 308).
Warning!G
When turning the wheel wrench to tighten
the wheel bolts, make sure you position
hands on the wrench in such a way that you
avoid injury to yourself, such as scraping
your hands against the wheel. Make sure
turning the wheel wrench will not scratch or
damage the wheel rim.
iFor information on storing the spare wheel
back into the trunk, see “Storing the spare wheel
after use” (
page 402).
!The maximum distance in emergency
mode depends on the vehicle’s load. It is
30 miles (50 km) if the vehicle is partially
loaded and 18 miles (30 km) if the vehicle is
fully loaded.
The point at which the maximum driving distance
begins in emergency mode is when the warning
message appears in the multifunction display
indicating that there is a loss of tire inflation
pressure.
Do not exceed the maximum speed of
50 mph (80 km/h).
