AUX and USB sockets
You can connect mobile audio devices such
as an MP3 player via the AUX and USB
sockets using commercially available
3.5 mm socket plug (AUX) or USB connector
cable (USB).
The AUX and USB sockets are located in the
glove box. 0002

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 aconvenience 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
R if the road, traffic, and weather
conditions do not make it advisable to
travel at a constant speed
R on slippery roads
Rapid changes in tire traction can result
in wheel spin and loss of control.
R when driving in fog
The use of the cruise control is
recommended for driving at a constant
speed for extended periods of time.

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 awheel. 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 180). 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: 0002

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
traction, 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
determined 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
vehicle 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 212).
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 0001on the tire
sidewall. These tires meet specific snow
traction performance requirements of the
Rubber 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
effectiveness of the ABS and ESP ®
in winter
operation.
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 210).
Always observe the speed rating of the
winter 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
following tire size: 140
