CAUTION! (Continued)
• Because of restricted traction device clearance be-
tween tires and other suspension components, it is
important that only traction devices in good con-
dition are used. Broken devices can cause serious
damage. Stop the vehicle immediately if noise
occurs that could indicate device breakage. Re-
move the damaged parts of the device before
further use.
• Install device as tightly as possible and then
retighten after driving about 1 ⁄
2
mile (0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
• Do not drive for prolonged period on dry pave-
ment.

CAUTION! (Continued)
• Observe the traction device manufacturer’s in-
structions on the method of installation, operating
speed, and conditions for use. Always use the
suggested operating speed of the device manufac-
turer’s if it is less than 30 mph (48 km/h).
• Do not use traction devices on a compact spare tire.
SNOW TIRES
Some areas of the country require the use of snow tires
during the winter. All season tires satisfy this require-
ment and can be indicated by the M+S designation on the
tire sidewall.
If you need snow tires, select tires equivalent in size and
type to the original equipment tires. Use snow tires only
in sets of four; failure to do so may adversely affect the
safety and handling of your vehicle.
