could jeopardize the user’s safety or the
safety of others.
! Because the ESP ®
operates
automatically, 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 otherwis eseriously
damage the brake system which is not
covered by the smart Limited Warranty.
i The ESP ®
will only function properly if
you use wheels of the recommended tire
size (Y page 210). Hydraulic brake assistant
The hydraulic brake assistant operates in
emergency situations. If you apply the
brakes very quickly, the hydraulic brake
assistant automatically provides full
brake boost, thereby potentially reducing
the braking distance.
X Apply continuous full braking pressure
until the emergency braking situation is
over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the
brakes function again as normal. The
hydraulic brake assistant is then
deactivated. G
WARNING
When the hydraulic brake assistant is
malfunctioning, the brake system is still
functioning normally, but without the
additional brake boost that would normally
be provided during an emergency braking
maneuver. Therefore, the braking distance
may increase. G
WARNING
The hydraulic brake assistant cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase braking efficiency beyond that afforded by
the condition of the vehicle brakes and
tires or the traction afforded. The
hydraulic brake assistant cannot prevent
accidents, including those resulting from
excessive speed in turns, following
another vehicle too closely, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of a hydraulic brake assistant
equipped vehicle must never be exploited
in a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others. Activating the hazard warning flasher
after an emergency braking maneuver
If you bring the vehicle to a complete stop
by strongly braking at a speed of more than
43 mph (70 km/h), the hazard warning
flasher comes on automatically as soon as
the vehicle is at a standstill. The hazard
warning flasher will remain on until it is
switched off using the hazard warning
flasher switch (Y page 66) or until the
speed of the vehicle has exceeded 6mph
(10 km/h). Anti-theft systems

WARNING
A vehicle with an electric motor produces
significantly lower noise levels than a
vehicle with a combustion engine. Other
motorists or pedestrians, especially those
who are visually or hearing impaired, may
be unable to hear your vehicle while it is
in motion. This is particularly true when
driving at lower speeds and during parking
maneuvers. At all times, it is the
responsibility of the driver to be aware of
their surroundings, especially in these low
speed situations. Otherwise other road
users could be seriously or fatally injured. G
WARNING
Make sure absolutely no objects are
obstructing the pedals’ range of motion.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats* or
carpets in the footwell, make sure the
pedals still have sufficient clearance.
During sudden acceleration or braking
maneuvers, the objects could get caught
between or beneath the pedals and restrict
your ability to brake or accelerate. This
could lead to accidents and/or injury.

WARNING
Getting out of your vehicle with the
transmission not fully engaged in park
position Pis dangerous. When the drive
system is switched off and the brakes are
released, the vehicle can be moved freely
with the gear selector lever in all
positions except park position P. Also,
when parked on an incline, park position
P alone may not prevent your vehicle from
moving, possibly hitting people or
objects.
Always engage the parking brake in
addition to shifting to park position P.
When parked on an incline, always turn the
front wheels towards the curb. G
WARNING
When leaving the vehicle, always remove the
key from the starter switch, take it with
you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could release the parking brake and/or
move the gear selector lever from park
position P, either of which could result in
an accident and/or serious personal
injury.
Brake pedal The brake pedal has two brake circuits
independent of each other. When the
ignition is switched on, a brake servo is
used during braking to increase pedal
force.
G
WARNING
Make sure absolutely no objects are
obstructing the pedals’ range of motion.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats* or
carpets in the footwell, make sure the
pedals still have sufficient clearance.
During sudden acceleration or braking
maneuvers, the objects could get caught
between or beneath the pedals and restrict
your ability to brake or accelerate. This
could lead to accidents and/or injury. G
WARNING
Considerably more effort will be required
to apply the brakes if
R the brake servo has failed
R a brake circuit has failed
R the ignition is switched off, e.g. for
towing the vehicle
The braking distance is likewise greater.
Make sure the drive system is active
whenever the vehicle is rolling. Have the
brake system repaired at an authorized
electric drive smart center, if there is a
fault in the brake system. 76

G
WARNING
During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorptio nofmoisture
from the atmosphere. Under extremely
strenuous operating conditions, this
moisture content can lead to the formation
of bubbles in the system, thus reducing the
system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement
interval.
The brake fluid level in the brake fluid
reservoir may be too low if the brake
warning lamp in the instrument cluster
comes on (Y page 21) although the parking
brake is released. !
If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the brake
system checked for brake pad thickness
and leaks immediately. Contact an
authorized electric drive smart center
immediately. Do not add brake fluid as
this will not solve the problem.
X Remove the service flap and insert it on

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

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

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*
