Use only charging cables which have been
approved and recommended for the vehicle.
Do not use:
R extension chords
R cable reels
R multiple sockets
R travel adapters
i When possible, only charge the
high‑voltage battery when the charge
level is below 80 %.
It is recommended to charge the
high‑voltage battery prior to reaching
less than 20% state of charge.
Discharged high‑voltage battery When the high‑voltage battery is
completely discharged, the drive system is
switched off. This protects the battery
from exhaustive discharge.
i By switching the ignition off and on
again, the drive system can be briefly
reactivate donce. This allows you to park
the vehicle safely.
Do not allow your vehicle to remain
stationary for more than 14 days with a
discharged, or nearly discharged,
high‑voltage battery. You can check the
charge level with the charge level gauge
(Y page 79).
High or low outside temperatures The efficiency of the high‑voltage battery
is temperature-dependent and decreases
at high or low temperatures .Additionally,
the electrolytes used can gel at very low
temperatures.
You can check the maximum capacity
available using the indicator in the
multifunction display (Y page 83).Energy consumption and range The available energy of the high‑voltage
battery is reduced by:
R
low outside temperatures
R switching on electrical consumers
At low temperatures and after being parked
for an extended period without charging,
the physical properties of the
high‑voltage battery:
R can cause a significant reductio ninthe
performance of the battery
R can lead to longer charging times
In extreme cases, you will not be able to
start the vehicle. For this reason, always
connect the charging cable or make sure the
battery is completely charged when
parking the vehicle in low outside
temperatures or for an extended period of
time.
Due to its physical properties, the
capacity of a high‑voltage battery
decreases over its lifespan.
Thus, the following are reduced:
R the maximum attainable range of the
vehicle
R the maximum performance output
(acceleration) of the vehicle
You can actively contribute to the
reduction of the vehicle's energy
consumption by:
R driving conservatively
R maintaining the vehicle regularly
R decreasing the use of electrical
consumers
Notes on battery care Avoid storing and transporting the vehicle
at high temperatures for extended periods
of time (e. g. container transport).

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
Tires and wheels>> Operation.
The traction grades, from highest to
lowest, are AA, A, B, and C. Those grades
represent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance.
Temperature G
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive
loading, either separately or in
combination, can cause excessive heat
build-up and possible tire failure.
The temperature grades are A (the highest),
B, and C, representing the tire’s resistance
to the generation of heat and its ability to
dissipate heat when tested under
controlled conditions on a specified
indoor laboratory test wheel. Sustained
high temperature can cause the material of
the tire to degenerate and reduce tire life,
and excessive temperature can lead to
sudden tire failure. The grade C
corresponds to a level of performance
which all passenger car tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law. Rotating tires
G
WARNING
Do not rotate front and rear wheels as they
have different dimensions, e.g. rim size,
wheel offset etc. Otherwise, the handling
can be affected and you could endanger
yourself and others. Thoroughly clean the mounting face of the
wheels and brake discs, i.e. the inner side
of the wheels/tires each time the wheels/
tires are changed. Check for and ensure
proper tire inflation pressure. G
WARNING
Have the tightening torque checked after
changing awheel. Wheels could become
loose if not tightened with a torque of
81 lb‑ft (110 Nm).
Only use genuine smart wheel bolts
specified for your vehicle’s rims.
For information on wheel change, see “Flat

Tire load rating
G
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
accident 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 0028is a numerical code
associated with the maximum load a tire
can support.
For example, a load rating of 91
corresponds to a maximum load of 1356 lbs
(615 kg) the tire is designed to support.
See also “Maximum tire load” (Y page 130)
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 136).
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
failure, 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 0029indicates 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)

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 0028and tire speed rating
0029.
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
capability.

Treadwear indicators
Narrow bands, sometimes called “wear
bars” that show across the tread of a tire
when only 1
/ 16 in (1.6 mm) of tread remains.
Uniform Tire Quality Grading Standards A tire information system that provides
consumers with ratings for a tire’s
traction, temperature and treadwear.
Ratings are determined by tire
manufacturers using U.S. government
testing procedures. The ratings are molded
into the sidewall of the tire.
Vehicle maximum load on the tire
Load on an individual tire that is
determined by distributing to each axle
its share of the maximum loaded vehicle
weight and dividing it by two.
Winter driving
Before the onset of winter, have your
vehicle winterized at an authorized
electric drive smart center.
This service includes:
R Check of anticorrosion and antifreeze
concentration.
R Addition of washer concentrate to the
water of the windshield/rear window.
Use a windshield washer concentrate
labeled for winter which is formulated
for temperatures below freezing point
(Y page 212).
R 12 V battery test. The capacity of the
12 V battery test drops with decreasing
ambient temperature.
R Tire change. Winter tires
G
WARNING
Winter tires with a tread depth of less
than 1
/ 6 in (4 mm) must be replaced. They
are no longer suitable for winter
operation.
Always use winter tires at temperatures
below 45 ¦(7¥) and whenever wintry road
conditions prevail. Not all M+S rated tires
provide special winter performance. Make
sure the tires you use show the mountain/
snowflake marking 0001on the tire
sidewall. These tires meet specific snow
traction performance requirements of the
Rubber Manufacturers Association (RMA)
and the Rubber Association of Canada (RAC)
and have been designed specifically for
use in snow conditions. Use of winter tires
is the only way to achieve the maximum
effectiveness of the ABS and ESP ®
in winter
operation.
For safe handling, make sure all mounted
winter tires are of the same make and have
the same tread design.
For information on winter tires for your
vehicle model, see the "Technical data"
section (Y page 210).
Always observe the speed rating of the
winter tires installed on your vehicle. If
the maximum speed for which your tires are
rated is below the speed rating of your
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available at your tire
dealer or any authorized electric drive
smart center. Snow chains*

Brakes
G
WARNING
Make sure not to endanger any other road
users when carrying out braking
maneuvers.
Refer to the description of the hydraulic
brake assistant (Y page 46).
! Because the ESP ®
operates
automatically, the ignition must be
switched off when the parking brake is
being tested on a brake test
dynamometer. Active braking action
through the ESP ®
may otherwise seriously
damage the brake system which is not
covered by the smart Limited Warranty.
Brake pad wear or a leak in the brake system
may be the reason for low brake fluid level
in the brake fluid reservoir.
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.
Have the brake system inspected
immediately. Contact an authorized
electric drive smart center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
electric drive smart center.
Only install brake pads and use brake fluid
recommended by smart.
Inclines When driving down long and steep grades,
do not depress the brake pedal permanently. Depress it in intervals
instead to reduce the vehicle speed. G
WARNING
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes
overheating, thereby significantly
reducing their effectiveness and your
ability to stop the vehicle in sufficient
time to avoid an accident.
High and low stresses After hard braking
,it is advisabl eto drive
on for some time, rather than immediately
park, so that the air stream will cool down
the brakes faster.
If your brake system is normally only
subjected to moderate loads, you should
occasionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads. G
WARNING
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Wet road surface G
WARNING
After driving in heavy rain for some time
without applying the brakes or through
water deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking
effect. Maintain a safe distance from
vehicles in front.
To help prevent brake disc corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to 142
