(Y page 123). Brake fluid
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 conditions, this mois-
ture 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 Mainte-
nance Booklet for replacement interval.
The brake fluid level in the brake fluid
reservoir may be too low if the brake warn- ing lamp in the instrument cluster comes on(Y page 23) 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
the front of the vehicle (Y page 123).
The brake fluid reservoir is located in the
front compartment on the passenger side. Checking brake fluid level
X
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. R If the brake fluid level has fallen
slightly below the minimum mark,
drive to an authorized electric drive
smart center.
R If the brake fluid level has fallen sig-
nificantly below the minimum mark,
call Roadside Assistance or an author- ized electric drive smart center.

Safety notes
Contact an authorized electric drive smart
center for information on tested and rec-
ommended rims and tires for summer and
winter operation. They can also offer
advice concerning tire service and pur-
chase. G
WARNING
Replace rims or tires with the same desig- nation, 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 suspen- Tires and wheels

sion 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 partic- ular rim type. Failure to do so can result in
the bolts loosening and possibly an acci-
dent.
Retreaded tires are not tested or recom-
mended 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 occur- red, you should turn on the hazard warning
flashers, carefully slow down, and drive
with caution to an area which is a safe dis-
tance 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 vehi- cle. 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
G
WARNING
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and energy con-
sumption of the vehicle, 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. 128

General:
Depending on the design standards used,
the tire size molded into the sidewall may
have no letter or a letter preceding the tire
size designation.
No letter preceding the size designation
(as illustrated above): Passenger car tire
based on European design standards. Letter “P” preceding the size designation:
Passenger car tire based on U.S. design
standards.
Letter “LT” preceding the size designa-
tion: Light Truck tire based on U.S. design
standards.
Letter “T” preceding the size designation: Temporary spare tires which are high pres-
sure compact spares designed for tempo-
rary emergency use only.
Tire width
Tire width :indicates the nominal tire
width in mm.
Aspect ratio
Aspect ratio ;is the dimensional rela-
tionship between tire section height and
section width and is expressed as a per-
centage. The aspect ratio is arrived at by
dividing section height by section width.
Tire code
Tire code =indicates the tire construc-
tion type. The “R” stands for radial tire
type. Letter “D” means diagonal or bias ply
construction; letter “B” means belted-bias
ply construction.
At the tire manufacturer’s option, any tire
with a speed capability above 149 mph
(240 km/h) can include a “ZR” in the size
designation (for example: 245/40 ZR 18).
For additional information, see “Tire
speed rating” (Y page 141).

WARNING
The tire load rating must always be at least
half of the GAWR of your vehicle. Otherwise, tire failure may result and cause an acci-
dent and/or serious personal injury to you
or others. 140
Tires and wheels>> Operation.

Always replace rims and tires with the same
designation, manufacturer and type as
shown on the original part. G
WARNING
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.
Tire load rating Ais a numerical code
associated with the maximum load a tire
can support.
For example, a load rating of 91 corre-
sponds to a maximum load of 1356 lbs
(615 kg) the tire is designed to support.
See also “Maximum tire load” (Y page 136)
where the maximum load associated with
the load index is indicated in kilograms
and lbs.
For additional information on tire load
rating, see “Load identification”
(Y page 142).
Tire speed rating G
WARNING
Even when permitted by law, never operate a
vehicle at speeds greater than the maximum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and
possibly resulting in an accident and/or
personal injury and possible death, for you and for others.
Regardless of the tire speed rating, local
speed limits should be obeyed. Use prudent driving speeds appropriate to prevailing
conditions.

If your tire includes “ZR” in the size
designation and no service description
is given, the tire manufacturer must be
consulted for the maximum speed capa-
bility.
If a service description is given, the
speed capability is limited by the speed
symbol in the service description.
Example: 245/40 ZR18 97Y.
