When a turn signal is set, unnecessary lines and areas are hidden.
Orientation lines overview
Meaning of the orientation lines and areas projected on screen ⇒ fig. 131. All distances of the
orientation lines refer to a vehicle on a level surface.
(1) Red: Safety distance. Area up to about 16 inches (40 cm) behind the vehicle on the road.
(2) Vehicle's width limits.
(3) Point to change steering angle.
When the yellow line touches the curb or any other parking space boundary, the steering wheel
must be turned in the opposite direction (close-up view).
(4) The area parallel to the vehicle that is needed for parking. The area shown must fit completely
into the parking space.
(5) Parked vehicle at the curb.
Parking
x Position the vehicle about 3 feet (1 meter) away from and parallel to the parking space and shift
into Reverse.
x On the screen of the navigation system, activate Mode 2 for parallel parking.
x Back up slowly and steer the vehicle so that the yellow surface on the screen is flush with the side
boundary of the parking space (such as the curb) and stops short of any obstacle (5), such as another
vehicle.
x Turn the steering wheel as far as it will go into the direction of the parking space and slowly back
up.
x Once the yellow line (3) touches the side of the parking space, for example, a marking or the curb
(close-up view), turn the steering wheel as far as it will go in the opposite direction.
x Continue backing up until the vehicles is positioned in the parking space parallel to the road. If
necessary, correct the parking position.
It may take up to 5 seconds for the area detected by the sensors to be displayed on the factory-
installed radio or navigation system screen.
Outer diameter
The diameter of a new, properly inflated tire.
Overall width
Total width measured at the exterior sidewalls of an inflated tire, including the additional width of
labeling, decorations, or protective bands or ribs.
Passenger car tire
A tire intended for use on passenger cars, multipurpose passenger vehicles, and trucks, that have a
gross vehicle weight rating (GVWR) of 10,000 pounds or less.
Ply
A layer of rubber-coated parallel cords.
Ply separation
A parting of rubber compound between adjacent plies.
Pneumatic tire
A mechanical device made of rubber, chemicals, fabric, and steel or other materials, that, when
mounted on an automotive wheel, provides the traction and contains the gas or fluid that sustains the
load.
Production options weight
The combined weight of installed regular production options weighing over 5 lbs (2.3 kg) more then the
standard items they replace, and not previously considered as curb weight or accessory weight. These
include, for example, heavy-duty brakes, ride levelers, roof rack, heavy-duty battery, and special trim.
Radial ply tires
A pneumatic tire in which the ply cords that extend to the beads are laid at substantially 90 degrees to
the centerline of the tread.
Recommended inflation pressure
The tire pressure recommended by the vehicle manufacturer for a tire of a specified size that has not
been driven for more than a couple of miles (kilometers) at low speeds in the 3 hour period before the
tire pressure is measured or adjusted.
Reinforced tire
A tire designed to operate at higher loads and at higher inflation pressures than the corresponding
standard tire.
Rim
The outer edge of a wheel upon which the tire beads are seated.
Rim diameter
The nominal diameter of the wheel's tire bead seating surface. If you change your wheel size, to
wheels of a different diameter, you will have to purchase new tires to match the new wheels.
Rim size
Designation means rim diameter and width.
Rim type designation
The industry or manufacturer's designation for a rim by style or code.
Rim width
The nominal distance between wheel rim flanges.
Section width
The linear distance between the exteriors of the sidewalls of an inflated tire, excluding elevations due
to labeling decoration, or protective bands.
Sidewall
The portion of a tire between the bead and the tread.
Sidewall separation
The parting of the rubber compound from the cord material in the sidewall.
Speed rating (letter code)
A standardized letter code indicating the maximum speed at which a tire is designed to be driven for
extended periods of time. The ratings range from 93 mph or 150 km/h (“P”) to 186 mph or (300 km/h)
“Y”.
The speed rating letter code, where applicable, is molded on the tire sidewall , Tire labeling. You may
not find this information on all tires because it is not required by law.
Tire Pressure Monitoring System
A system that detects when at least one of a vehicle's tires is underinflated and illuminates a low tire-
pressure warning light.
Tread
The portion of a tire that normally touches the road.
Tread rib
A tread section running circumferentially around a tire.
Tread separation
Tire failure caused by the tread pulling away from the tire carcass.
Tread wear indicators (TWI)
Raised areas within the main tread grooves that show, visually, when tires are worn and near the end
of their useful life 278, Tread depth and tread wear indicators.
Uniform Tire Quality Grading (UTQG)
A tire information system developed by the U.S. National Highway Traffic Safety Administration
(NHTSA) that is designed to help buyers compare tires. UTQG is not a safety rating, nor is it a
guarantee that a tire will last for a certain number of miles or perform a certain way. It gives tire buyers
more information to compare with factors such as price, brand loyalty and dealer recommendations.
Under UTQG, tires are graded by the tire manufacturers in 3 areas: tread wear, traction and
temperature resistance. UTQG information is molded into the tire sidewalls.
U.S. DOT Tire Identification Number (TIN)
A tire's serial number. It begins with the letters “DOT” (“Department of Transportation”) and indicates
that the tire meets all federal standards. The next 2 numbers or letters indicate the plant where the tire
was manufactured. The last 4 numbers represent the week and year of manufacture.
For example, the numbers 1709 mean that the tire was produced in the 17th week of 2009. Any other
numbers are marketing codes used by the tire manufacturer. This information is used to help identify
affected consumers if a tire defect requires a recall.
Vehicle capacity weight
The total rated cargo, luggage and passenger load. Passenger load is 150 lbs (68 kilograms) times the
vehicle's total seating capacity (as listed on the label inside the driver door).
Vehicle maximum load on the tire
The load on an individual tire that is determined by taking each axle's share of the maximum loaded
vehicle weight (GAWR) and dividing by 2.
Vehicle normal load on the tire
The load on an individual tire that is determined by taking each axle's share of the curb weight,
accessory weight, and normal occupant weight (distributed according to the table below) and dividing
by 2.
Wheel size designation
Wheel rim diameter and width.
Occupant loading and distribution for vehicle normal load for various designated seating
capacities
Designated seating capacity,
number of occupants
Vehicle normal load, number
of occupants
Occupant distribution in a
normally loaded vehicle
2, 3, or 4 2 2 in front
5 3 2 in front, 1 in back
