If you have a dissimilar spare wheel and tire,
then it is intended for temporary use only.
This means that if you need to use it, you
should replace it as soon as possible with a
road wheel and tire assembly that is the
same size and type as the road tires and
wheels that were originally provided by us.
If the dissimilar spare tire or wheel is
damaged, you should replace it rather than
repair it.

Tire Change Procedure WARNING: The jack supplied with
this vehicle is only intended for changing
wheels. Do not use the vehicle jack other
than when you are changing a wheel in an
emergency. WARNING:
Check that the vehicle
jack is not damaged or deformed and the
thread is lubricated and clean. WARNING:
When one of the front
wheels is off the ground, the transmission
alone will not prevent the vehicle from
moving or slipping off the jack, even if the
transmission is in park (P). WARNING:
To help prevent your
vehicle from moving when changing a
wheel, shift the transmission into park (P),
set the parking brake and use an
appropriate block or wheel chock to
secure the wheel diagonally opposite to
the wheel being changed. For example,
when changing the front left wheel, place
an appropriate block or wheel chock on
the right rear wheel. WARNING:
Always use the jack
provided as original equipment with your
vehicle. If using a jack other than the one
provided, make sure the jack capacity is
adequate for the vehicle weight, including
any vehicle cargo or modifications. If you
are unsure if the jack capacity is adequate,
contact the authorized dealer. WARNING:
Failure to follow these
guidelines could result in an increased risk
of loss of vehicle control, injury or death. WARNING:
Use only the specified
jacking points. If you use other positions,
you may damage the body, steering,
suspension, engine, braking system or the
fuel lines. WARNING:
Do not work on your
vehicle when the jack is the only support.
If the vehicle slips off the jack, you or
someone else could be seriously injured. WARNING:
Never place anything
between the vehicle jack and your vehicle.

WARNING: When you install a wheel, always remove any corrosion, dirt or foreign m\
aterials present on the mounting surfaces of the
wheel or the surface of the wheel hub, brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners that attach
the rotor to the hub so they do not interfere with the mounting surfaces\
of the wheel. Installing wheels without correct metal-to-metal contact
at the wheel mounting surfaces can cause the wheel nuts to loosen and th\
e wheel to come off while your vehicle is in motion, resulting in
loss of vehicle control, personal injury or death. lb.ft (Nm)
