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.

Tires and wheels
Safety notes
Contact an authorized electric drive smart
center for information on tested and
recommended rims and tires for summer
and winter operation. They can also offer
advice concerning tire service and
purchase. G
WARNING
Replace rims or tires with the same
designation, manufacturer and type as
shown on the original part. For further
information contact an authorized electric
drive smart center. If incorrectly sized
rims and tires are mounted, the wheel
brakes or suspension components can be
damaged. Also, the operating clearance of
the wheels and the tires may no longer be
correct. G
WARNING
Worn, old tires can cause accidents. If the
tire tread is worn to minimum tread depth,
or if the tires have sustained damage,
replace them.
When replacing rims, only use genuine
smart wheel bolts specified for the
particular rim type. Failure to do so can
result in the bolts loosening and possibly
an accident.
Retreaded tires are not tested or
recommended by smart, since previous
damage cannot always be recognized on
retreads. The operating safety of the
vehicle cannot be assured when such tires
are used. G
WARNING
If you feel a sudden significant vibration
or ride disturbance, or you suspect that
possible damage to your vehicle has
occurred, you should turn on the hazard
warning flashers, carefully slow down, and
drive with caution to an area which is a safe
distance from the road. Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to the
nearest authorized electric drive smart
center or tire dealer for repairs.
G
WARNING
Do not drive with a flat tire. A flat tire
affects the ability to steer or brake the
vehicle. You could lose control of the
vehicle. Continued driving with aflat tire
or driving at high speed with a flat tire
will cause excessive heat build-up and
possibly a fire.
Modifications to the brake system and
wheels and the use of brake dust rings are
not permissible. Important guidelines
R Only use sets of tires and rims of the same
type and make.
R Tires must be of the correct size for the
rim.
R Break in new tires for approximately
60 miles (100 km) at moderate speeds.
R Regularly check the tires and rims for
damage. Dented or bent rims can cause
tire pressure loss and damage to the tire
beads.
R If vehicle is heavily loaded, check tire
inflation pressure and correct as
required.
R Do not allow your tires to wear down too
far. Adhesion properties on wet roads are
sharply reduced at tread depths of less
than 1
/ 8 in (3 mm). Recommended tire inflation pressure

G
WARNING
If the tire inflation pressure drops
repeatedly, check the tires for punctures
from foreign objects and/or whether air is
leaking from the valves or from around the
rim.
Tire temperature and tire inflation
pressure are also increased while driving,
depending on the driving speed and the
tire load.
Potential problems associated with
underinflated and overinflated tires Underinflated tires
G
WARNING
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and energy
consumption of the vehicle, and are more
likely to fail from being overheated.

the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
Check the tire inflation pressure at least
once a month.
Check and adjust the tire inflation
pressure when the tires are cold
(Y page 123). 124
Tires and wheels>> Operation.

Checking tire inflation pressure
manually
Follow the steps below to achieve correct
tire inflation pressure:
X Remove the cap from the valve on one tire.
X Firmly press a tire gauge onto the valve.
X Read the tire inflation pressure on tire
gauge and check against the
recommended tire inflation pressure on
the Tire and Loading Information
placard on the driver’s door B‑pillar
(Y page 128). If necessary, add air to
achieve the recommended tire inflation
pressure.
X If you have overfilled the tire, release
tire inflation pressure by pushing the
metal stem of the valve with e.g. a tip of
a pen. Then recheck the tire inflation
pressure with the tire gauge.
X Install the valve cap.
X Repeat this procedure for each tire.
Tire Pressure Monitoring System
(TPMS)* Your vehicle may be equipped with a
Tire
Pressure Monitoring System (TPMS).
It monitors the tire inflation pressure in
all four tires .Awarning is issued to alert
you to a decrease in pressure in one or more
of the tires.
The Tire Pressure Monitoring System
(TPMS) is equipped with a combination low
tire pressure/TPMS malfunction telltale in
the instrument cluster. Depending on how
the telltale illuminates, it indicates a low
tire pressure condition or a malfunction in
the TPMS system itself:
R If the telltale illuminates continuously,
one or more of your tires is significantly
underinflated. There is no malfunction
in the TPMS.
R If the telltale flashes for 60 seconds and
then stays illuminated, the TPMS system
itself is not operating properly. The TPMS only functions on wheels that are
equipped with the proper electronic
sensors. G
WARNING
The TPMS does not indicate a warning for
wrongly selected inflation pressures.
Always adjust tire inflation pressure
according to the Tire and Loading
Information placard on the driver’s door
B‑pillar.
The TPMS is not able to issue a warning due
to a sudden dramatic loss of pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by
carefully applying the brakes and avoiding
abrupt steering maneuvers. G
WARNING
Each tire should be checked monthly when
cold and inflated to the inflation pressure
recommended by the vehicle manufacturer
on the Tire and Loading Information
placard. If your vehicle has tires of a
different size than the size indicated on
the Tire and Loading Information placard,
you should determine the proper tire
inflation pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure
monitoring system (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly
underinflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure.
Driving on a significantly underinflated
tire causes the tire to overheat and can lead
to tire failure.
Underinflation also increases energy
consumption, reduces tire tread life, and
may affect the vehicle’s handling and
stopping ability. Please note that the TPMS
is not a substitute for proper tire
maintenance, and it is the driver’s Tires and wheels
125>> Operation.
* optional Z

responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination
of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately 1 minute and then remain
continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
incompatible replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on
your vehicle to ensure that the replacement
or alternate tires and wheels allow the
TPMS to continue to function properly.
i If a condition causing the TPMS to
malfunction develops, it may take up to
10 minutes for the system to signal a
malfunction using the TPMS telltale
flashing and illumination sequence.
The telltale extinguishes after a few
minutes driving if the malfunction has
been corrected.
i Operating radio transmission
equipment (e.g. wireless headsets, two-
way radios) in or near the vehicle could
cause the TPMS to malfunction. i

Restarting the TPMS G
WARNING
It is the driver’s responsibility to
calibrate the TPMS on the recommended
cold inflation pressure. Underinflated
tires affect the ability to steer or brake
and might cause you to lose control of the
vehicle.
When you restart the TPMS, the system sets
new reference values for each tire.
The TPMS must be restarted when you have
adjusted the tire inflation pressure to a
new level (e.g. because of differen tload or
driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures. 126
