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

* optional

keep in mind that a considerably higher
degree of effort is necessary to brake and
steer the vehicle. Adapt your driving
accordingly. Brakes
G
WARNING
Make sure not to endanger any other road
users when carrying out braking maneu-
vers.
Refer to the description of the hydraulic
brake assistant (Y page 47).
! Because the ESP ®
operates automati-
cally, the ignition must be switched off
when the parking brake is being tested
on a brake test dynamometer. Active
braking action through the ESP ®
may oth-
erwise seriously damage the brake sys-
tem which is not covered by the smart
Limited Warranty.
Brake pad wear or a leak in the brake system may be the reason for low brake fluid level
in the brake fluid reservoir.
The brake fluid level in the brake fluid
reservoir may be too low if the brake warn- ing lamp in the instrument cluster comes on
(Y page 23) although the parking brake is
released.
Have the brake system inspected immedi-
ately. Contact an authorized electric drive
smart center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
electric drive smart center.
Only install brake pads and use brake fluid
recommended by smart. Inclines G
WARNING
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheat-
ing, thereby significantly reducing their
effectiveness and your ability to stop the
vehicle in sufficient time to avoid an acci- dent.
Please observe the following guidelines to
avoid that the permitted maximum speed is
exceeded when driving on downhill grades:
R Do not move the gear selector lever to N.
R Recuperation is limited, if:
- the high-voltage battery is fully
charged or too cold
- the power electronics or the electric
motor is overheated.
When driving down long and steep grades, do not depress the brake pedal perma-
nently. Depress it in intervals instead to
reduce the vehicle speed.
High and low stresses After hard braking, it is advisable to drive
on for some time, rather than immediately
park, so that the air stream will cool down
the brakes faster.
If your brake system is normally only sub-
jected to moderate loads, you should occa- sionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads. G
WARNING
Make sure not to endanger any other road
users when carrying out these braking
maneuvers. 148
Driving instructions>> Operation.

Standing water
Do not drive through flooded areas or water of unknown depth. Before driving through
water, determine its depth. Never acceler-
ate before driving into water.
If you must drive through standing water,
drive slowly to prevent water from entering
R the front compartment
R the engine compartment

if road, weather and traffic condi-
tions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approx-
imately 14 m) every second.
Telephones and two-way radios G
WARNING
Never operate radio transmitters equipped with a built-in or attached antenna (i.e.
without being connected to an external
antenna) from inside the vehicle while the
drive system is switched on. Doing so couldlead to a malfunction of the vehicle’s elec-
tronic system, possibly resulting in an
accident and/or serious personal injury.
Radio transmitters, such as a mobile phone
or a citizens band unit should only be used inside the vehicle if they are connected to an antenna that is installed on the outside
of the vehicle.
Refer to the radio transmitter operation
instructions regarding use of an external
antenna. Coolant temperature
During severe operating conditions and
stop-and-go city traffic, the coolant tem-
perature may rise. ! Excessive coolant temperature causes
the red coolant temperature warning
lamp ? in the instrument cluster to
come on.
The drive system should not be operated
with the red coolant temperature warn-
ing lamp ?illuminated. Doing so may
cause serious damage to the drive system
and the high-voltage battery, which is
not covered by the smart Limited War-
ranty.
