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
brake carefully every now and then on
R
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
keep a good safe distance from the
R
vehicle in front and drive carefully
press the brake carefully at the end of the
R
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:
Shift gears in a timely manner.
R
Avoid frequent acceleration and
R
deceleration.
Keep tires at the recommended inflation
R
pressures.
Remove carriers* when not in use.
R
Remove unnecessary loads.
R
Allow engine to warm up under low load
R
use.
Have all maintenance work performed at
R
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.
