surfaces.
Certain models are equipped with "all-season" tires, which provide a som\
ewhat higher degree of road
holding on slippery surfaces than tires without the "all-season" rating.\
However, for optimum road
holding on icy or snow-covered roads, we recommend suitable winter tires\
on all four wheels.
When replacing tires, be sure that the new tires are the same size desig\
nation, type (radial) and
preferably from the same manufacturer, on all four wheels. Otherwise the\
re is a risk of altering the
vehicle's roadholding and handling characteristics.
Storing wheels and tires
When storing complete wheels (tires mounted on rims), they should be s\
uspended off the floor or placed
on their sides on the floor.
Tires not mounted on rims should be stored on their sides or standing up\
right, but should not be
suspended. CAUTION!
Tires should preferably be stored in a cool, dry, dark place, and should\
never be stored in close
proximity to solvents, gasoline, oils, etc.
Tread wear indicator
The tires have wear indicator strips running across or parallel to the t\
read. The letters TWI are printed on
the side of the tire. When approximately 1/16" (1.6 mm) is left on the\
tread, these strips become visible
and indicate that the tire should be replaced. Tires with less than 1/16\
" (1.6 mm) tread offer very poor
traction.
When replacing worn tires, it is recommended that the tire be identical \
in type (radial) and size as the
one being replaced. Using a tire of the same make (manufacturer) will \
prevent alteration of the driving
characteristics of the vehicle.

self supporting run flat tires.
Tires of this type have specially reinforced sidewalls that make it poss\
ible to continue driving in the
event of a drop in inflation pressure. Tires of this type are mounted on\
special rims.
NOTE: Self supporting run flat tires are only available in conjunction with T\
PMS.
If a self supporting run flat tire should lose inflation pressure, the y\
ellow TPMS warning symbol (
) in
the instrument panel lights up to alert the driver, and a message will b\
e shown in the text window in the
instrument panel.
If this occurs, reduce vehicle speed to a maximum of 50 mph (80 km/h).\
The vehicle can be driven
approximately 50 miles (80 km), or somewhat farther if the vehicle is \
not heavily loaded. The tire should
be replaced as soon as possible.
Hard braking and sudden steering maneuvers should be avoided.
In certain cases, it may be difficult to see which self supporting run f\
lat tire is defective.
To determine which tire is damaged, check the inflation pressure of all \
four tires.
WARNING!
l Only specially trained persons should mount self supporting run flat tir\
es.
l If self supporting run flat tires are mounted, the vehicle must be equip\
ped with a Tire Pressure
Monitoring System.
l After a low pressure warning has been displayed, do not exceed 50 mph (\
80 km/ h).
l Avoid severe cornering and hard braking, and minimize the distance trave\
led before replacing the
self supporting run flat tire.
l Self supporting run flat tires cannot be repaired. They must be replaced\
if damaged or punctured.

CAUTION!
- The vehicle must not be driven with wheels of different dimensions or \
with a spare tire other than
the one that came with the vehicle. The use of different size wheels can\
seriously damage your
vehicle's transmission.
- Correct tightening torque on wheel bolts must be observed. The wheel b\
olts should never be greased
or lubricated. The extended, chromed wheel bolts must not be used with s\
teel rims, as they make it
impossible to fit the hub caps.
- Locking wheel bolts can be used on both aluminum and steel wheels. If \
hub caps are used on steel
wheels, the locking wheel bolt should be mounted in the hole as far from\
the tire's inflation valve as
possible. It would otherwise not be possible to mount the hub cap on the\
wheel.

Changing wheels
- Position the jack correctly on the bar in the attachment (see illustr\
ation above) and crank while
simultaneously guiding the base of the jack to the ground. The base of t\
he jack must be flat on a level,
firm, non-slippery surface. Before raising the vehicle, check that the j\
ack is still correctly positioned in
the attachment.
- Raise the vehicle until the wheel to be changed is lifted off the grou\
nd.
- Unscrew the wheel bolts completely and carefully remove the wheel so a\
s not to damage the threads on
the studs.
