>> Operation
!
Always use a windshield washer concen

trate labeled for winter where temperatures
may fall below freezing point. Failure to do so
could result in damage to the washer system/
reservoir.
>Premix the windshield washer fluid in a
suitable container.
Observe mixing ratios depending on the
outside temperature (

page 308).
>Use the tab to pull cap1 upwards.
>Refill the windshield washer reservoir.
>Push cap
1 onto the windshield washer
reservoir.
Brake fluidThe brake fluid level in the brake fluid
reservoir may be too low if the brake warning
lamp in the instrument cluster comes on
(
page 34) 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 smart center immedi

ately. Do not add brake fluid as this will not
solve the problem.
The brake fluid reservoir is located in the
front compartment on the driver’s side.

Cap
G
Warning!
During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorption of
moisture from the atmosphere. Under
extremely strenuous operating condi

tions, 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 re

placed regularly. Refer to your vehicle’s
Maintenance Booklet for replacement

Checking brake fluid level
>Perform a visual check of the brake fluid
reservoir.
The brake fluid level is correct when it is
between the minimum mark and the maximum
mark.
• If the brake fluid level has fallen slightly
below the minimum mark, drive to an
authorized smart center.
• If the brake fluid level has fallen
significantly below the minimum mark, call
Roadside Assistance or an authorized
smart center.

Driving instructions

>> Operation
BrakesRefer to the description of the hydraulic
brake assistant (

page 75).
!
Because the ESP
® operates automatically,
the engine must be shut off (key in starter
switch position0) when
• the parking brake is being tested on a
brake test dynamometer
• the vehicle is being towed with the front
axle raised
Active braking action through the
ESP
® may
otherwise seriously damage the brake system
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 warning
lamp in the instrument cluster comes on
(

page 34) although the parking brake is
released.
Have the brake system inspected immediately.
Contact an authorized smart center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized smart
center.
Only install brake pads and use brake fluid
recommended by smart.Inclines
!
When driving down long and steep grades,
relieve the load on the brakes by shifting into
a lower gear to use the engine’s braking
power. This helps prevent overheating of the
brakes and reduces brake pad wear.
When using the engine’s braking power, a
drive wheel may not spin for an extended pe

riod of time, e.g. on slippery road surfaces.
This may cause serious damage to the drive

train which is not covered by the smart
Limited Warranty.
G
Warning!
Make sure not to endanger any other
road users when carrying out braking
maneuvers.

Driving instructions
214
>> OperationNew brake pads
Only install brake pads recommended by
smart.
G
Warning!
The accumulation of salt on break disks
and brake pads reduces braking effec

tiveness and increases the distance nec

essary to come to a complete. This could
potentially cause an accident and/or
personal injury.
To avoid this risk, you should
• brake carefully every now and then on
salted roads in order to remove any
layer of salt on the brake disk and
brake pad, but do so without endanger

ing any other road users.
• keep a good safe distance from the
vehicle in front and drive carefully.
• 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 disk.
G
Warning!
If other than recommended brake pads
are installed, or other than recommended
brake fluid is used, the braking proper

ties of the vehicle can be degraded to an
extent that safe braking is substantially
impaired. This could result in an acci

dent.
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 re

duced braking effect by pressing harder
on the brake pedal and adapt your driv

ing style accordingly. The same applies
after brake pads or brake disks have
been changed.

• if the brake circuit fails or the brake fluid
level in the brake fluid reservoir is too low.
>Stop the vehicle immediately in a safe
location.
>Do not continue to drive.
>Turn off the engine.
>Do not add brake fluid as this will not solve
the problem.
>Set the parking brake when leaving the

• when the TPMS detects a loss of pressure in
at least one tire.
>Carefully bring the vehicle to a halt,
avoiding abrupt steering and braking
maneuvers. Observe the traffic situation
around you
.
>Check and correct tire inflation pressure
as required (

page 190).
G
Warning!
Driving with the brake warning lamp illu

minated can result in an accident. Have
your brake system checked immediately
if the brake warning lamp stays on.
Do not add brake fluid before checking
the brake system.

Coolant temperature warning lamp
Illuminates:
• when the ignition is switched on.
The warning lamp goes out if the engine is
running.
• if the coolant is too hot.
>Stop the vehicle immediately in a safe
location.
>Do not continue to drive.
>Turn off the engine.
>Set the parking brake when leaving the
vehicle.
>Contact Roadside Assistance or an autho

rized smart center.If the coolant level has fallen below the
marking bar on the coolant reservoir
(

page 178):
>Add coolant as required.
>Have the coolant system checked for leaks
at an authorized smart center.
!
Among other possible causes, the
poly
V
belt could be broken. Do not continue
to drive. Otherwise, the engine will overheat
