cators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle
Certification Label for the size designation of
your tire. The Load Index and Speed Symbol
for your tire will be found on the original
equipment tire sidewall.
It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s
handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifica-
tions or capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
WARNING!
• Do not use a tire, wheel size, load rating,
or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and per-
WARNING!
formance characteristics, resulting in
changes to steering, handling, and brak-
ing of your vehicle. This can cause un-
predictable handling and stress to steer-
ing and suspension components. You
could lose control and have a collision
resulting in serious injury or death. Use
only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index
or capacity, other than what was origi-
nally equipped on your vehicle. Using a
tire with a smaller load index could re-
sult in tire overloading and failure. You
could lose control and have a collision.
• Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false speedom-
eter and odometer readings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all sea-
sons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identified
by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in
sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
Summer Or Three Season Tires — If
Equipped
Summer tires provide traction in both wet
and dry conditions, and are not intended to
be driven in snow or on ice. If your vehicle is
equipped with Summer tires, be aware these
tires are not designed for Winter or cold
driving conditions. Install Winter tires on your
vehicle when ambient temperatures are less
than 40°F (5°C) or if roads are covered with
ice or snow. For more information, contact an
authorized dealer.
Summer tires do not contain the all season
designation or mountain/snowflake symbol
on the tire sidewall. Use Summer tires only in

Minimum Ground Clearance (Reference A)
The clearance value is measured next to the
lower edge of the differential. This value also
defines those for the “Approach Angle” the
“Departure Angle” and the “Breakover
Angle”.
Dimensions are expressed in inches (mm)
and refer to the vehicle equipped with its
original tires.Approach Angle (Reference B)
The approach angle is determined by the
horizontal line of the road surface, and by the
tangent line passing between the front wheel,
and the most projecting low point of the car.
The wider the angle, the lower the chance to
hit an obstacle with the body or chassis, when
climbing a steep slope or overcoming an
obstacle.Departure Angle (Reference C)
The departure angle is determined by the
same lines of the “Approach Angle”, and
refers to the rear part of the vehicle.
Breakover Angle (Reference D)
The value of the “Breakover Angle” is linked
to the ground clearance of the vehicle and
indicates the attitude of the vehicle to over-
come a wedge, more or less steep, preventing
