it counterclockwise with the handle,
making sure the handle remains firmly
fitted onto the jack handle extension.
3. After the tire is lowered completely to the ground, remove the holding brack-

When storing the spare tire, put it in place
with the outer side of the wheel facing up.
Then secure the tire, taking care that the
tire goes straight up without catching on
any other part, to prevent it from flying
forward during a collision or s udden brak-
ing.2. Block the wheel diagonally opposite the flat tire to keep the vehicle from
rolling when it is j acked up.
When blocking the wheel, place a wheel
block from the front for the front wheels
or from the rear for the rear wheels.Ty p e A

3 Jack handle
CAUTION
Make sure they are each securely
fixed with screws.
6. After making sure that no one is inthe vehicle, raise it high enough so
that the spare tire can be installed.
Remember you will need more ground
clearance when putting on the spare tire
than when removing the flat tire.
To raise the vehicle, insert the jack handle
extension in to the jack (it is a loose fit)
and turn it clockwise with the handle,
making sure the handle remains firmly
fitted onto the jack handle extension. As
the jack touches the vehicle and begins
to fit, doublecheck that it is properly
positioned.
CAUTION
Never get under the vehicle when the
vehicle is supported by the jack
alone.

then tap it firmly with the side or heel of
your hand to snap it into place.
CAUTION
Take due care in handling the orna-
ment to avoid unexpected personal
injury.
11. Check the air pressure of the re- placed tire.
Adjust the air pressure to the specification
designated on page 312 in Section 8. If
the pressure is lower, drive slowly to the
nearest service station and fill to the cor-
rect pressure.
Do not forget to reinstall the tire inflation
valve cap as dirt and moisture could get
into the valve core and possibly cause air
leakage. If the cap is missing, have a new
one put on as soon as possible.
12. Restow all the tools, jack and flat tire securely.
With a spare tire of the same wheel type
as the installed tires—
As soon after changing wheels as pos-
sible, tighten the wheel nuts to the torque
specified on page 312 in Section 8 with
a torque wrench. Have a technician repair
the flat tire.
With a spare tire of different wheel type
from the installed tires—
As soon after changing wheels as pos-
sible, tighten the wheel nuts to the torque
specified on page 312 in Section 8 with
a torque wrench. Have a technician repair
the flat tire and replace the spare tire with
it.CAUTION
Before driving, make sure all the
tools, jack and flat tire are securely
in place in their storage location to
reduce the possibility of personal in-
jury during a collision or s udden
braking.
