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 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 22) 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 immediately. Do
not add brake fluid as this will not solve
the problem.

Tires and wheels
Safety notes
Contact an authorized 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.
GWarning!
Replace rims or tires with the same
designation, manufacturer and type as
shown on the original part. For further
information contact an authorized 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.
GWarning!
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.GWarning!
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 smart center or tire
dealer for repairs.
GWarning!
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 a flat 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
GWarning!
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel
economy, and are more likely to fail from
being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
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.
Your vehicle is equipped with the Tire and
Loading Information placard located on
the driver’s door B‑pillar ( Y page 120).
The tire inflation pressure should be
checked regularly. Only adjust the tire
inflation pressure on cold tires. The tires
can be considered cold if the vehicle has
been parked for at least 3 hours or driven
less than 1 mile (1.6 km). Depending on the
ambient temperature, the driving speed
and the tire load, the tire temperature
changes. When the tire temperature
changes by 18 ¦ (10 ¥), the tire inflation
pressure will change by approximately
1.5 psi (0.1 bar). Keep this in mind when
checking tire inflation pressure on warm
tires and adjust the tire pressure only if
the tire inflation pressure is too low for
the current operating conditions. If you
check the tire inflation pressure when the
tires are warm, the reading will be higher
than the cold reading. This is normal. Do
not let air out to match the specified cold
tire inflation pressure. Otherwise, the
tire will be underinflated.
Follow recommended cold tire inflation
pressures listed on Tire and Loading
Information placard on the driver’s door
B‑pillar.
Keeping the tires properly inflated
provides the best handling, tread life and
riding comfort.
In addition to the Tire and Loading
Information placard on the driver’s door
B‑pillar, also consult the tire inflation
pressure label (if available) on the inside
of the filler flap for any additional
information pertaining to special driving
situations. For more information, see
“Important notes on tire inflation
pressure” ( Y page 116).
i Data shown on Tire and Loading
Information placard example are for
illustration purposes only. Tire data are
specific to each vehicle and may vary
from data shown in the following
illustration. Refer to Tire and Loading
Information placard on vehicle for
actual data specific to your vehicle.Tires and wheels115>> Operation.451_AKB; 3; 22, en-USd2ureepe,Version: 2.11.8.12009-07-27T09:36:34+02:00 - Seite 115Z

Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the

Tire and Loading Information placard on
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 115).
Checking tire inflation pressure
manually
Follow the steps below to achieve correct
tire inflation pressure:
XRemove the cap from the valve on one tire.XFirmly press a tire gauge onto the valve.XRead 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 120). If necessary, add air to
achieve the recommended tire inflation
pressure.XIf 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.XInstall the valve cap.XRepeat 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. A warning 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.
GWarning!
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.
GWarning!
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
Tires and wheels117>> Operation.* optional451_AKB; 3; 22, en-USd2ureepe,Version: 2.11.8.12009-07-27T09:36:34+02:00 - Seite 117Z

interference that may cause
undesired operation of the device.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
Restarting the TPMSGWarning!
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 different load or
driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.
XUsing the Tire and Loading Information
placard on the driver’s door B‑pillar
( Y page 120), make sure the tire
inflation pressure of all four tires is
correct.
i Restart the TPMS after adjusting the
tire inflation pressure to the inflation
pressure recommended for the vehicle
operating condition. Tire pressure
should only be adjusted on cold tires.
Observe the recommended tire inflation
pressure on the Tire and Loading
Information placard on the driver’s door
B‑pillar ( Y page 120).
XPress Restarting TPMS button 0046.
The combination low tire pressure/TPMS
malfunction telltale in the instrument
cluster ( Y page 22) flashes for
approximately 5 seconds and then goes
out.
After driving a few minutes the system
verifies that the current tire inflation
pressures are within the system’s
specified range. Afterwards the current
tire inflation pressures are accepted as
reference pressures and then monitored.
Maximum tire inflation pressure
GWarning!
Never exceed the max. tire inflation
pressure. Follow recommended tire
inflation pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel
economy, and are more likely to fail from
being overheated.

Loading the vehicle
Two labels on your vehicle show how much
weight it may properly carry.
1)The Tire and Loading Information
placard can be found on the driver’s
door B‑pillar. This placard tells you
important information about the
number of people that can be in the
vehicle and the total weight that can be
carried in the vehicle. It also contains
information on the proper size and
recommended tire inflation pressures
for the original equipment tires on
your vehicle.2)The certification label, also found on
the driver’s door B‑pillar, tells you
about the gross weight capacity of your
vehicle, called the Gross Vehicle
Weight Rating (GVWR). The GVWR
includes the weight of the vehicle, all
occupants, fuel and cargo. The
certification label also tells you about
the front and rear axle weight capacity,
called the Gross Axle Weight Rating(GAWR). The GAWR is the total allowable
weight that can be carried by a single
axle (front or rear). Never exceed the
GVWR or GAWR for either the front axle
or rear axle.0046Driver’s door B‑pillar

Certification label
Even after careful determination of the
combined weight of all occupants and cargo
as to not exceed the permissible load
limit, you must make sure your vehicle
never exceeds the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for either the front or rear
axle. You can obtain the GVWR and GAWR
from the certification label. The
certification label can be found on the
driver’s door B‑pillar, see “Technical
data” ( Y page 198).
Gross Vehicle Weight Rating (GVWR) means:
The total weight of the vehicle, all
occupants, and all cargo must never exceed
the GVWR.
Gross Axle Weight Rating (GAWR) means:
The total allowable weight that can be
carried by a single axle (front or rear).To assure that your vehicle does not exceed
the maximum permissible weight limits
(GVWR and GAWR for front and rear axle),
have the loaded vehicle (including driver,
passenger, and all cargo) weighed on a
suitable commercial scale.
Maximum tire load
GWarning!
Do not overload the tires by exceeding the
specified load limit as indicated on the
