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 conditions
first before operating system controls
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 immediate
vicinity (e.g. horns, emergency rescue
vehicles, police vehicles, etc.). You could
otherwise cause an accident. G
WARNING
If you wish to have an audio system other
than an original smart audio system fitted
in your vehicle, please always have the
necessary work performed at an authorized
smart center.
This is particularly important if your
vehicle 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.

Cruise control*
The cruise control maintains the speed you
set for your vehicle automatically. On
downhill grades, the cruise control does
not brake the vehicle via the brake system.
The cruise control can only use the braking
power of the engine. You must apply the
brakes yourself in order to reduce the
vehicle speed. The cruise control will then
be canceled. G
WARNING
The cruise control is a convenience system
designed to assist the driver during
vehicle operation. The cruise control
cannot take road, traffic, and weather
conditions into account. The driver is and
must always remain responsible for the
vehicle’s speed and for safe brake
operation. Do not use the cruise control

Unidirectional tires offer added
advantages, such as better hydroplaning
performance.
To benefit, however, you must
make sure the tires rotate in the direction
specified.
An arrow on the sidewall indicates the
intended direction of rotation (spinning)
of the tire. Tire care and maintenance
G
WARNING
Regularly check the tires for damage.
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle.
Worn, old tires can cause accidents. If the
tire

tread is badly worn, or if the tires have
sustained damage, replace them.
Check the tire inflation pressure at least
once a month. For more information on
checking tire inflation pressure, see
“Recommended tire inflation pressure”
(Y page 125).
Tire inspection Every time you check the tire inflation
pressure, you should also inspect your
tires for the following
R
excessive treadwear ( Y page 133)
R cord

or fabric showing through the tire’s
rubber
R bumps, bulges, cuts, cracks or splits in
the tread or side of the tire
Replace the tire if you find any of the above
conditions. Life of tire G
WARNING
Tires should be replaced after 6 years,
regardless of the remaining tread.
The

service life of a tire is dependent upon
varying factors including but not limited
to
R driving style
R tire inflation pressure
R distance driven
Tread depth G
WARNING
Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately

1
/ 16 in
(1.6 mm), we recommend that you do not allow
your tires to wear down to that level. As
tread depth approaches 1
/ 8 in (3 mm), the
adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction
varies widely.
Do not allow your tires to wear down too far.
Adhesion properties on wet roads are
sharply reduced at tread depths of less
than 1
/ 8 in (3 mm).
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and
become visible at a tread depth of
approximately 1
/ 16 in (1.6 mm), at which
point the tire is considered worn and
should be replaced.
Recommended minimum tire tread depth:
Summer tires 1
/ 8 in (3 mm)
Winter tires 1
/ 6 in (4 mm) Tires and wheels
133>> Operation. Z

Treadwear indicator
: appears as a solid
band across the tread.
Storing tires !
Keep unmounted tires in a cool, dry
place with as little exposure to light as
possible.

Protect tires from contact with
oil, grease and fuels.
Cleaning tires !
Never use a round nozzle to power wash
tires.

The intense jet of water can result
in damage to the tire.
Always replace a damaged tire. Uniform Tire Quality Grading
Standards
The Uniform Tire Quality Grading is a U.S.
Government requirement designed to give
drivers consistent and reliable
information regarding tire performance.
Tire manufacturers are required to grade
tires based on three performance factors: treadwear
:,
traction ;, and temperature
resistance =. Although not a Government
of Canada requirement, all tires made for
sale in North America have these grades
branded on the sidewall.
i For illustration purposes only. Actual
data on tires are specific to each vehicle
and may vary from data shown in above
illustration.
Quality grades can be found, where
applicable, on the tire sidewall between
tread shoulder and maximum section width.
For example: Treadwear Traction Temperature
200 AA A
All passenger car tires must conform to
federal

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 U.S. 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 G
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. 134
Tires and wheels
>> Operation.

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
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
loading, either separately or in
combination, can cause excessive heat
build-up and possible tire failure.
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
corresponds 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. Rotating tires
G
WARNING
Do not rotate front and rear wheels as they
have different dimensions, e.g. rim size,
wheel offset etc. Otherwise, the handling
can be affected and you could endanger
yourself and others. Thoroughly clean the mounting face of the
wheels

and brake discs, i.e. the inner side
of the wheels/tires each time the wheels/
tires are changed. Check for and ensure
proper tire inflation pressure. G
WARNING
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
81 lb‑ft (110 Nm).
Only use genuine smart wheel bolts
specified for your vehicle’s rims.
For

information on wheel change, see “Flat
tire” (Y page 186). Tire labeling
Besides tire name (sales designation) and
manufacturer name, a number of markings
can be found on a tire.
Following are some explanations for the
markings on your vehicle’s tires: :
Uniform Quality Grading Standards
(Y page 134)
; DOT, Tire Identification Number (TIN)
(Y page 138)
= Maximum tire load (Y page 132)
? Maximum tire inflation pressure
(Y page 129) Tires and wheels

>> Operation. Z

Depending upon the weather and/or road
surface (conditions), the tire traction
varies widely.
Specified
tire inflation pressures must be
maintained. This applies particularly if
the tires are subject to high loads (e.g.
high speeds, heavy loads, high ambient
temperatures). 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 vehicle.
Continued driving with a flat tire or
driving at high speed with a flat tire will
cause excessive heat build-up and possibly
a fire.
For more information, see “Tires and
wheels” (Y page 124). Hydroplaning
Depending 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 cautiously when it is raining. Tire traction
The
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. G
WARNING
If ice has formed on the road, tire traction
will be substantially reduced. Under such
weather

conditions, drive, steer and brake
with extreme caution.
smart recommends winter tires
(Y page 142) with a minimum tread depth of approximately
1
/ 6 in (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
considerably greater than when the road is
not covered with snow or ice. Exercise
appropriate caution.
! Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. Otherwise, the
drivetrain could be damaged, which is
not covered by the smart Limited
Warranty. Tire speed rating
Regardless of the tire speed rating, local
speed

limits should be obeyed. Use prudent
driving speeds appropriate to prevailing
conditions. G
WARNING
Even when permitted by law, never operate
a vehicle at speeds greater than the
maximum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire
failure,

causing loss of vehicle control and
possibly resulting in an accident and/or
personal injury and possible death, for you
and for others.
An electronic speed limiter prevents your
vehicle from exceeding a speed of 90 mph
(145 km/h).
The factory equipped tires on your vehicle
may have a tire speed rating above the
maximum speed permitted by the
electronic speed limiter.
Make sure your tires have the required tire
speed rating as specified for your vehicle
in the “Technical data section” Driving instructions
