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

R
Remove unnecessary loads.
R Have all maintenance work performed at
the intervals specified in the Mainte-
nance Booklet and as required by the
Maintenance System. Contact an author-
ized electric drive smart center.
Energy consumption is also increased by
driving in stop-and-go traffic, on short

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 smart center or tire dealer for
repairs.
Treadwear indicators (TWI) are required by law. These indicators are located in six
places on the tread circumference and
become visible at a tread depth of approx-
imately 1
/ 16 in (1.6 mm), at which point the
tire is considered worn and should be
replaced.
The treadwear indicator appears as a solid
band across the tread. G
WARNING
Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately 1
/ 16 in
(1.6 mm), we recommend that you do not allow your tires to wear down to that level. As
tread depth approaches 1
/ 8 in (3 mm), the
adhesion properties on a wet road are
sharply reduced. Depending upon the weather and/or road
surface (conditions), the tire traction var- ies widely.
Specified tire inflation pressures must be maintained. This applies particularly if
the tires are subject to high loads (e.g.
high speeds, heavy loads, high ambient
temperatures). G
WARNING
Do not drive with a flat tire. A flat tire will affect your ability to steer or brake and maycause you to lose control of the vehicle.
Continued driving with a flat tire or driv-
ing at high speed with a flat tire will cause
excessive heat build-up and possibly a
fire.
For more information, see “Tires and
wheels” (Y page 127). Hydroplaning
Depending on the depth of the water layer
on the road, hydroplaning may occur
resulting in a loss of control, even at low
speeds and with new tires. Reduce vehicle
speed, avoid track grooves in the road and
apply brakes cautiously when it is raining. Tire traction
The safe speed on a wet, snow covered or icy
road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside temperatures are close to the freezing
point. G
WARNING
If ice has formed on the road, tire traction will be substantially reduced. Under such
weather conditions, drive, steer and brake
with extreme caution.
smart recommends winter tires (Y page 146)
with a minimum tread depth of approx- 150
