As soon as the vehicle establishes an Inter-
net connection, you can also use the "Vehi-
cle Homepage" at home during the charging
process. Changes you have made via the
"Vehicle Homepage" are adopted after the
charging process is complete. This data
transmission ends after approximately
three days. Intelligent charging management
If you wish to charge economically and with
minimal damage to the battery, you must set
a departure time ( Ypage 90). This option
to optimize the charging process depends
on your electricity contract and the local
power supplier. Your vehicle detects this
option automatically. Depending on the
departure time which is set, the charging
process of the high-voltage battery may not
be started immediately or may be inter-
rupted during the process. Front compartment

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 0043.
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.

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-
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 128

Unidirectional tires offer added advan-
tages, such as better hydroplaning per-
formance. To benefit, however, you must
make sure the tires rotate in the direction
specified.
An arrow on the sidewall indicates the
intended direction of rotation (spinning)
of the tire. Tire care and maintenance
G
WARNING
Regularly check the tires for damage. Dam-
aged tires can cause tire inflation pres-
sure loss. As a result, you could lose control
of your vehicle.
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
Check the tire inflation pressure at least
once a month. For more information on
checking tire inflation pressure, see
“Recommended tire inflation pressure”
(Y page 128).
Tire inspection Every time you check the tire inflation
pressure, you should also inspect your
tires for the following
R
excessive treadwear (Y page 137)
R cord or fabric showing through the tire’s
rubber
R bumps, bulges, cuts, cracks or splits in
the tread or side of the tire
Replace the tire if you find any of the above
conditions. Life of tire G
WARNING
Tires should be replaced after 6 years,
regardless of the remaining tread.
The service life of a tire is dependent upon
varying factors including but not limited
to
R driving style
R tire inflation pressure
R distance driven
Tread depth 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.
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).
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.
Recommended minimum tire tread depth:
Summer tires 1
/ 8 in (3 mm)
Winter tires 1
/ 6 in (4 mm) Tires and wheels
137>> Operation. Z

Treadwear indicator
0043appears as a solid
band across the tread.
Storing tires !
Keep unmounted tires in a cool, dry
place with as little exposure to light as
possible. Protect tires from contact with
oil, grease and fuels.
Cleaning tires !
Never use a round nozzle to power wash
tires. The intense jet of water can result
in damage to the tire.
Always replace a damaged tire. Uniform Tire Quality Grading Stand-
ards The Uniform Tire Quality Grading is a U.S.
Government requirement designed to give
drivers consistent and reliable informa-
tion regarding tire performance. Tire
manufacturers are required to grade tires
based on three performance factors: tread- wear
0043, traction 0044, and temperature
resistance 0087. Although not a Government
of Canada requirement, all tires made for
sale in North America have these grades
branded on the sidewall.
i For illustration purposes only. Actual
data on tires are specific to each vehicle
and may vary from data shown in above
illustration.
Quality grades can be found, where appli-
cable, on the tire sidewall between tread
shoulder and maximum section width. For
example: Treadwear Traction Temperature
200 AA A
All passenger car tires must conform to
federal safety requirements in addition to
these grades.
Treadwear The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified U.S. government test course. For
example, a tire graded 150 would wear one
and one-half (1 1
/ 2 ) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving hab-
its, service practices and differences in
road characteristics and climate.
Traction G
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics. 138
Tires and wheels>> Operation.

tire failure may result and cause an acci-
dent and/or serious personal injury to you
or others.
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 0083is 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 maxi-
mum 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. Tire speed rating
0084indicates the
approved maximum speed for the tire.
Summer tires Index Speed rating
Q up to 100 mph (160 km/h)
R up to 106 mph (170 km/h)
S up to 112 mph (180 km/h)
T up to 118 mph (190 km/h)
H up to 130 mph (210 km/h)
V up to 149 mph (240 km/h)

ZR...Y above 186 mph (300 km/h)
ZR...(Y) above 186 mph (300 km/h)
ZR above 149 mph (240 km/h)
R
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 ZR18). To determine the maximum
speed capability of the tire, the service
description for the tire must be referred
to.
The service description is comprised of
tire load rating 0083and tire speed rating
0084.
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.
In this example, “97Y” is the service
description. The letter “Y” designates

ity of the tire is limited to 186 mph
(300 km/h).
R Any tire with a speed capability above
186 mph (300 km/h) must include a “ZR” in
the size designation AND the service
description must be placed in parenthe-
sis. Example: 275/40 ZR 18 (99Y). The “(Y)”
speed rating in parenthesis designates
the maximum speed capability of the tire
as being above 186 mph (300 km/h). Con-
sult the tire manufacturer for the actual
maximum permissible speed of the tire.
