They are indicated as reference distances to
objects. The lines and colors in the display indi-
cate distances from the back bumper line
Ain
the illustration.
11.5 ft (0.5 m) red
23 ft (1 m) yellow
37 ft (2 m) green
410 ft (3 m) green
The vehicle clearance lines are wider than
the actual clearance.
DIFFERENCE BETWEEN
PREDICTED AND ACTUAL
DISTANCES
The distance guide line and the vehicle width
guide line should be used as a reference only
when the vehicle is on a level, paved surface. The
distance viewed on the monitor is for reference
only and may be different than the actual distance
between the vehicle and displayed objects.

Backing up on a steep uphill
When backing up the vehicle up a hill, the dis-
tance guide lines and the vehicle width guide
lines are shown closer than the actual distance.
For example, the display shows 3 ft (1.0 m) to the
place
A, but the actual 3 ft (1.0 m) distance on
the hill is the place
B. Note that any object on
the hill is further than it appears on the monitor.
Backing up on a steep downhill
When backing up the vehicle down a hill, the
distance guide lines and the vehicle width guide
lines are shown farther than the actual distance.
For example, the display shows 3 ft (1.0 m) to the
place
A, but the actual 3 ft (1.0 m) distance on
the hill is the place
B. Note that any object on
the hill is closer than it appears on the monitor.

1Tire size (example: P215/65R15 95H)
1. P: The “P” indicates the tire is de- signed for passenger vehicles (not all
tires have this information) .
2. Three-digit number (215): This num- ber gives the width in millimeters of
the tire from sidewall edge to side-
wall edge.
3. Two-digit number (65): This number, known as the aspect ratio, gives the
tire’s ratio of height to width. 4. R: The “R” stands for radial.
5. Two-digit number (15): This number
is the wheel or rim diameter in inches.
6. Two- or three-digit number (95): This number is the tire’s load index. It is a
measurement of how much weight
each tire can support. You may not
find this information on all tires be-
cause it is not required by law. 7. H: Tire speed rating. You should not
drive the vehicle faster than the tire
speed rating.

DOT (Department of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
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
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1 1/2) 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 and C
The traction grades, from highest to lowest, are
AA, A, B, and C. Those grades represent the
tire’s ability to stop on wet pavement as mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. A tire marked C may have poor traction
performance.
