WARNING: Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive at
a safe speed.
Truck and utility vehicles can differ from
some other vehicles. Your vehicle could be
higher to allow it to travel over rough terrain
without getting stuck or damaging
underbody components. The differences that
make your vehicle so versatile also make it
handle differently than an ordinary passenger
car. Always maintain steering wheel control,
especially in rough terrain. Since sudden
changes in terrain can result in abrupt
steering wheel motion, make sure you grip
the steering wheel from the outside. Do not
grip the spokes. Drive cautiously to avoid
vehicle damage from concealed objects such as rocks and stumps. Drive slower in strong
crosswinds which can affect the normal
steering characteristics of your vehicle. Be
extremely careful when driving on pavement
made slippery by loose sand, water, gravel,
snow or ice.
Note:
Do not use four-wheel drive high or
four-wheel drive low mode on dry, hard
surfaced roads. Doing so can produce
excessive noise, increase tire wear and can
damage drive components.
FOUR-WHEEL DRIVE LIMITATIONS
Operating Four-Wheel Drive with a
Spare or Mismatched Tires
(If Equipped)
On four-wheel drive vehicles, the size of the
spare tire can affect the four-wheel drive
system. If there is a significant difference
between the size of the spare tire and the
remaining tires, you could have limited
four-wheel drive functionality. When driving
with the full-size dissimilar spare wheel and
tire assembly, we recommend that you do
not: •
Exceed
50 mph (80 km/h) with a
four-wheel drive mode turned on.
• Use a four-wheel drive mode on dry
pavement.
Driving with the full-size dissimilar spare
wheel and tire assembly can limit four-wheel
drive functionality. You can experience the
following:
• Additional noise from the transfer case
or other drive components.
Use of a dissimilar spare wheel and tire
assembly can lead to impairment of the
following:
• Comfort and noise.
• Winter weather driving capability.
• Wet driving capability.
• Four-wheel drive capability.
Note: Your vehicle could have a front air
dam that can become damaged, due to
reduced ground clearance, when taking your
vehicle off-road. You can remove this air
dam by removing the eight bolts that secure
it.

LOCATING THE TIRE LABEL
You will find a Tire Label containing tire
inflation pressure by tire size and other
important information located on the
B-Pillar or the edge of the driver's door.

Certification Labels (page 336).
DEPARTMENT OF
TRANSPORTATION UNIFORM TIRE
QUALITY GRADES Tire Quality Grades apply to new
pneumatic passenger car tires. The
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Treadwear 200
Traction AA Temperature A.
These Tire Quality Grades are
determined by standards that the United
States Department of Transportation has
set.
Tire Quality Grades apply to new
pneumatic passenger car tires. They do
not apply to deep tread, winter-type
snow tires, space-saver or temporary
use spare tires, light truck or LT type
tires, tires with nominal rim diameters of
10 to 12 inches or limited production tires
as defined in Title 49 Code of Federal
Regulations Part 575.104 (c)(2).
U.S. Department of Transportation Tire
quality grades: The U.S. Department of
Transportation requires us to give you
the following information about tire
grades exactly as the government has
written it. Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear 1½ times as well on the
government course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
Traction AA A B C
WARNING:
The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning or peak
traction characteristics.
