Air pressure The amount of air inside the tire pressing
outward on each square inch of the tire. Air pressure is expressed in pounds per square
inch (psi), or kilopascal (kPa) or bars.
Aspect ratio Dimensional relationship between tire
section height and section width expressed
in percentage.
Bar Another metric unit for air pressure. There
are 14.5038 pounds per square inch (psi) to
1 bar; there are 100 kilopascals (kPa) to
1 bar.
Bead The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the
rim.
Cold tire inflation pressure Tire inflation pressure when your vehicle
has been sitting for at least 3 hours or
driven no more than 1 mile (1.6 km).
Curb weight The weight of a motor vehicle with standard
equipment including the maximum capa-
city of fuel, oil, and coolant, and, if so
equipped, air conditioning and additionaloptional equipment, but without passen-
gers and cargo.
DOT (Department of Transportation) A tire branding symbol which denotes the
tire meets requirements of the U.S. Depart- ment of Transportation. GAWR (Gross Axle Weight Rating) The GAWR is the maximum permissible axle
weight. The gross vehicle weight on each
axle must never exceed the GAWR for the
front and rear axle indicated on the cer-
tification label located on the driver’s
door B‑pillar.
GVW (Gross Vehicle Weight) The GVW comprises the weight of the vehi-
cle including fuel, tools, installed acces-
sories, passengers and cargo. The GVW must never exceed the GVWR indicated on the
certification label located on the driver’s
door B‑pillar.
GVWR (Gross Vehicle Weight Rating) This is the maximum permissible vehicle
weight of the fully loaded vehicle (weight
of the vehicle including all options, pas-
sengers, fuel, and cargo. It is indicated on
certification label located on the driver’s door B‑pillar.
Kilopascal (kPa) The metric unit for air pressure. There are
6.9 kPa to 1 psi; another metric unit for air
pressure is bars. There are 100 kilopas-
cals (kPa) to 1 bar.
Maximum load rating The maximum load in kilograms and pounds
that can be carried by the tire.
Maximum loaded vehicle weight The sum of curb weight, accessory weight,
total load limit and production options
weight.
Maximum permissible tire inflation
pressure This number is the greatest amount of air
pressure that should ever be put in the tire.144

Normal occupant weight
The number of occupants the vehicle is
designed to seat, multiplied by 68 kilo-
grams (150 lbs).
Occupant distribution The distribution of occupants in a vehicle
at their designated seating positions.
Production options weight The combined weight of those installed
regular production options weighing over
5 lbs (2.3 kilograms) in excess of those
standard items which they replace, not
previously considered in curb weight or
accessory weight, including heavy duty
brakes, ride levelers, roof rack, heavy duty
battery, and special trim.
PSI (Pounds per square inch) A standard unit of measure for air pres-
sure.
Recommended tire inflation pressure The recommended tire inflation pressure
for normal driving conditions is listed on
the Tire and Loading Information placard
located on driver’s door B‑pillar and pro-
vides best handling, tread life and riding
comfort.
Rim A metal support for a tire or a tire and tube
assembly upon which the tire beads are
seated.
Sidewall The portion of a tire between the tread and
the bead. TIN (Tire Identification Number) Unique identifier which facilitates
efforts by tire manufacturers to notify
purchasers in recall situations or other
safety matters concerning tires and gives
purchasers the means to easily identify
such tires. The TIN is comprised of “Man-
ufacturer’s identification mark”, “Tire
size”, “Tire type code” and “Date of manu-
facture”.
Tire load rating Numerical code associated with the maxi-
mum load a tire can support.
Tire ply composition and material used This indicates the number of plies or the
number of layers of rubber-coated fabric
in the tire tread and sidewall. Tire manu-
facturers also must indicate the ply mate-
rials in the tire and sidewall, which
include steel, nylon, polyester, and others.
Tire speed rating Part of tire designation; indicates the
speed range for which a tire is approved.
Total load limit Rated cargo and luggage load plus 68 kilo-
grams (150 lbs) times the vehicle’s desig-
nated seating capacity.
Traction Force exerted by the vehicle on the road via
the tires. The amount of grip provided.
Tread The portion of a tire that comes into con-
tact with the road. Tires and wheels

Treadwear indicators
Narrow bands, sometimes called “wear
bars” that show across the tread of a tire
when only 1
/ 16 in (1.6 mm) of tread remains.
Uniform Tire Quality Grading Standards A tire information system that provides
consumers with ratings for a tire’s trac-
tion, temperature and treadwear. Ratings
are determined by tire manufacturers
using U.S. government testing procedures.
The ratings are molded into the sidewall of the tire.
Vehicle maximum load on the tire Load on an individual tire that is deter-
mined by distributing to each axle its
share of the maximum loaded vehicle
weight and dividing it by two. Winter driving
Before the onset of winter, have your vehi- cle winterized at an authorized electric
drive smart center.
This service includes:
R Check of anticorrosion and antifreeze
concentration.
R Addition of washer concentrate to the
water of the windshield/rear window.
Use a windshield washer concentrate
labeled for winter which is formulated
for temperatures below freezing point
(Y page 218).
R 12 V battery test. The capacity of the
12 V battery test drops with decreasing
ambient temperature.
R Tire change. Winter tires
G
WARNING
Winter tires with a tread depth of less than 1 / 6 in (4 mm) must be replaced. They are no
longer suitable for winter operation.
Always use winter tires at temperatures
below 45 ¦(7¥) and whenever wintry road
conditions prevail. Not all M+S rated tires provide special winter performance. Make
sure the tires you use show the mountain/
snowflake marking ion the tire side-
wall. These tires meet specific snow trac-
tion performance requirements of the Rub- ber Manufacturers Association (RMA) and
the Rubber Association of Canada (RAC) and
have been designed specifically for use in
snow conditions. Use of winter tires is the only way to achieve the maximum effective-
ness of the ABS and ESP ®
in winter opera-
tion.
For safe handling, make sure all mounted
winter tires are of the same make and have
the same tread design.
For information on winter tires for your
vehicle model, see the "Technical data"
section (Y page 216).
Always observe the speed rating of the win-
ter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available at your tire
dealer or any authorized electric drive
smart center. Snow chains*
! Remember that snow chains must always
be compatible with the tire sizes of a
vehicle. Snow chains that are approved
by smart are only permitted for the fol-
lowing tire size:
175/55 R15 on the rear axle. 146

WARNING
Always replace wheel bolts that are dam-
aged or rusted.
Never apply oil or grease to wheel bolts. Damaged wheel hub threads should be
repaired immediately. Do not continue to
drive under these circumstances! Contact
an authorized electric drive smart center
or call Roadside Assistance.
Incorrect wheel bolts or improperly tight-
ened wheel bolts can cause the wheel to
come off. This could cause an accident. Be
sure to use the correct wheel bolts. G
WARNING
Only use genuine smart wheel bolts. Other
wheel bolts may come loose.
Do not tighten the wheel bolts when the
vehicle is raised. Otherwise the vehicle
