effect. Maintain a safe distance from
vehicles in front.
To
help prevent brake disc corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes. G
WARNING
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Limited braking effect on salted roads Remember that the effect of the brakes can
be

limited on salted road surfaces. A layer
of salt can form on brake discs and brake
pads, considerably reducing the friction
between the brake disc and the brake pad.
The effect is most noticeable after long
trips without braking, e.g. on the highway,
and after the vehicle has been parked for
several hours. G
WARNING
The accumulation of salt on brake discs and
brake pads reduces braking effectiveness
and increases the distance necessary to
come to a complete standstill. This could
potentially cause an accident and/or
personal injury.
To avoid this risk, you should
R brake carefully every now and then on
salted

roads in order to remove any layer
of salt on the brake disc and brake pad,
but do so without endangering any other
road users
R keep a good safe distance from the
vehicle in front and drive carefully
R press the brake carefully at the end of the
trip and again when beginning the next
trip in order to remove any salt residues
from the brake disc New brake pads Only install brake pads recommended by
smart.
G
WARNING
If other than recommended brake pads are
installed,
or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired.
This could result in an accident. G
WARNING
New brake pads will not achieve their
optimal braking effect until after several
hundred miles (kilometers). This means
that you must compensate for the reduced
braking effect by pressing harder on the
brake pedal and adapt your driving style
accordingly. The same applies after brake
pads or brake discs have been changed. Drive sensibly - save fuel
Fuel consumption, to a great extent,
depends on driving habits and operating
conditions.
To save fuel you should:
R Shift gears in a timely manner.
R Avoid frequent acceleration and
deceleration.
R Keep

tires at the recommended inflation
pressures.
R Remove carriers* when not in use.
R Remove unnecessary loads.
R Allow engine to warm up under low load
use.
R Have all maintenance work performed at
the intervals specified in the
Maintenance Booklet and as required by
the Maintenance System. Contact an
authorized smart center.
Fuel consumption is also increased by
driving in cold weather, in stop-and-go
traffic, on short trips, and in hilly areas. Driving instructions

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
