G
Warning!
In order to avoid distraction which could
lead to an accident, the driver should
enter system settings with the vehicle at
a standstill and operate the system only
when road and traffic conditions permit.
Always pay full attention to traffic condi

tions first before operating system con

trols while driving.
Bear in mind that at a speed of just
30 mph (approximately 50 km/h), your
vehicle is covering a distance of 44 feet
(approximately 14 m) every second.
G
Warning!
Always select a volume that allows you to
still hear ambient sound in your immedi

ate vicinity (e.g. horns, emergency res

cue vehicles, police vehicles, etc.). You
could otherwise cause an accident.
G
Warning
If you wish to have a radio other than an
original smart radio fitted in your vehi

cle, please always have the necessary
work performed at an authorized smart
center.
This is particularly important if your ve

hicle is fitted with a radio preinstallation.
Improper connection can result in the
failure of important vehicle functions,
thereby endangering the operating
safety of your vehicle and thus your own
safety and that of other people.

Tires and wheels
>> Operation
203
Quality grades can be found, where applica

ble, on the tire sidewall between tread shoul

der and maximum section width. For example:
All passenger car tires must conform to fed

eral safety requirements in addition to these
grades.
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
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
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
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance.
Temperature
The temperature grades are A (the highest),
B, and C, representing the tire’s resistance to
the generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel.Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failure. The grade C corre

sponds to a level of performance which all
passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher
levels of performance on the laboratory test
wheel than the minimum required by law.

G
Warning!
The traction grade assigned to this tire is
based on straight
ahead braking trac

tion tests, and does not include acceler

ation, cornering, hydroplaning, or peak
traction characteristics.
G
Warning!
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive load

ing, either separately or in combination,
can cause excessive heat build
up and
possible tire failure.

(
page 182).
HydroplaningDepending on the depth of the water layer on
the road, hydroplaning may occur resulting in
a loss of control, even at low speeds and with
new tires. Reduce vehicle speed, avoid track
grooves in the road and apply brakes cau

tiously when it is raining.
Tire tractionThe safe speed on a wet, snow covered or icy
road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside
temperatures are close to the freezing point.smart recommends winter tires
(
page 208)

with a minimum tread depth of approximately 1/6in (4 mm) on all four wheels for the winter
season to ensure normal balanced handling
characteristics. On packed snow, they can
reduce your stopping distance compared to
summer tires.
Stopping distance, however, is still consider

ably greater than when the road is not cov

ered with snow or ice. Exercise appropriate
caution.
!
Avoid spinning of a drive wheel for an ex

tended period when driving off on slippery
road surfaces. Otherwise, the the drivetrain

G
Warning!
Do not drive with a flat tire. A flat tire will
affect your ability to steer or brake and
may cause you to lose control of the vehi

cle. Continued driving with a flat tire or
driving at high speed with a flat tire will
cause excessive heat build
up and possi

bly a fire.
G
Warning!
If ice has formed on the road, tire trac

tion will be substantially reduced. Under
such weather conditions, drive, steer and
brake with extreme caution.
