Replacing transmitter battery
Notes
The remote control’s transmitter battery is
almost spent when the turn signals flash
rapidly nine times in a row when locking
the vehicle.
i If you do not replace the transmitter
battery, after about 100 more times you

XReplace the transmitter battery.
or
XHave the transmitter battery replaced at
an smart center.GWarning!
Batteries contain poisonous and corrosive
substances. Therefore keep the batteries
out of reach of children.
If a battery is swallowed, seek medical help
immediately.
Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states/provinces
require sellers of batteries to accept old
batteries for recycling.
Replacing battery
Replacement battery: CR 2016 button cell
! Replace the remote control’s
transmitter battery every two years at
the latest. Otherwise there is a danger of
leakage. The remote control could be
damaged.
XInsert a suitable object such as a coin
into the slot at the eyelet of the key
housing.XCarefully turn the coin until key housing
top half 0046 is unlatched.XOpen key housing top half 0046 to the side.XRemove transmitter battery 0047 from the
board.
! Check the polarity when inserting the
new transmitter battery. You could
otherwise damage parts of the electrical
system. When inserting the batteries,
make sure they are clean and free of lint.
XInsert the new transmitter battery.XPress both halves of the key housing
together again.XCheck the operation of the remote
control.Replacing transmitter battery163>> Practical hints.451_AKB; 3; 22, en-USd2ureepe,Version: 2.11.8.12009-07-27T09:36:34+02:00 - Seite 163Z

The vehicle’s battery is drained by use
of the electric air pump. You should
therefore keep the engine running — in
the open air — while inflating the tire.
006EElectric air pump switchXPress I on electric air pump switch 006E.
The electric air pump is switched on and
inflates the tire.
i First, the sealant is pumped into the
tire. The pressure may briefly increase
to a high value. This is normal and not an
indication of a malfunction. Do not
switch off the electric air pump.XLet the electric air pump inflate the tire
for a maximum of ten minutes.
Pressure gauge 0047 must display at least
26 psi (1.8 bar).GWarning!
The filler hose can become hot during
inflation.
Please exercise appropriate caution.
! Do not operate the electric air pump
longer than ten minutes without
interruption. Otherwise it may overheat.
You may operate the electrical air pump
again after it has cooled off.
XIf a tire inflation pressure of at least
26 psi (1.8 bar) is not attained, turn off
the electric air pump by pressing 0 on
electric air pump switch 006E.XUnscrew the end of filler hose 0088 from
tire valve 0072.XAfter clearing the area around the
vehicle of people and obstacles, drive
vehicle back or forth very slowly
approximately 30 ft (10 m).
This serves to better distribute the tire
sealant material inside the tire.XScrew the end of filler hose 0088 onto tire
valve 0072.XInflate the tire again.GWarning!
If a tire inflation pressure of 26 psi
(1.8 bar) is not attained, the tire is too
severely damaged for the tire sealant to
provide a reliable tire repair.
In this case, the tire sealant cannot
properly seal the tire.
Do not drive the vehicle.
Contact the nearest smart center for
assistance or call Roadside Assistance.

GWarning!
Failure to follow these instructions can
result in severe injury or death.
Observe all safety instructions and
precautions when handling automotive
batteries.
Never lean over batteries while
connecting, you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with
eyes, skin or clothing. In case it does,
immediately flush affected area with water
and seek medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
GWarning!
Do not place any metal objects on a battery.
You could otherwise cause a short circuit
and the battery’s highly flammable
chemicals could ignite.
Never allow any metal object to contact both
battery terminals or the positive terminal
and the vehicle body at the same time. This
might short circuit the battery and ignite
the highly flammable and explosive
hydrogen gas generated by the battery,
causing serious personal injury.
GWarning!
Keep flames or sparks away from battery,
avoid improper connection of jumper
cables, smoking, etc.
R When disconnecting the battery, always
disconnect the negative terminal first,
followed by positive terminal.

R Do not loosen or disconnect the battery
terminal clips while the engine is
running or the key is in the starter
switch.
! Never loosen or detach battery terminal
clamps while the engine is running or the
key is in the starter switch. Otherwise

Jump starting
GWarning!
Failure to follow these directions will
cause damage to the electronic components,
and can lead to a battery explosion and
severe injury or death.
Never lean over batteries while connecting
or jump starting, you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with
eyes, skin or clothing. In case it does,
immediately flush affected area with
water, and seek medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and very explosive.
Keep flames or sparks away from battery,
avoid improper connection of jumper
cables, smoking, etc.
Attempting to jump start a frozen battery
can result in it exploding, causing
personal injury.
Read all instructions before proceeding.
! Do not tow‑start vehicle. You could
otherwise seriously damage the
transmission which is not covered by the
smart Limited Warranty.
! Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using
a battery quick charge unit.
If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized smart
center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter and may
present a fire risk.
Make sure the jumper cables do not have
loose or missing insulation.
Make sure the cable clamps do not touch
any other metal part while the other end
is still attached to a battery.
If the battery is discharged, the engine can
be started with jumper cables and the fully
charged battery of another vehicle or an
equivalent starter pack. Observe the
following:
R Access to the battery is not possible on
all vehicles. If you cannot access the
battery in your vehicle provide jumpJump starting183>> Practical hints.451_AKB; 3; 22, en-USd2ureepe,Version: 2.11.8.12009-07-27T09:36:34+02:00 - Seite 183Z

start power by an external battery or
starter pack.
R Jump starting should only be performed
when the engine and catalytic converter
are cold.
R Do not start the engine if the battery is
frozen. Let the battery thaw out first.
R Only jump start from batteries with the
same voltage rating (12 V). Jump starting
with a more powerful battery could
damage the vehicle’s electrical system.
Such damage will not be covered by the
smart Limited Warranty.
R Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
R Always make sure the jumper cables are
not on or near pulleys, fans or other parts
that move when an engine is started or
running.
R Should the battery be drained
completely, let the donating power
source charge the vehicle for several
minutes before reattempting the
starting process.GWarning!
Keep flames or sparks away from battery. Do
not smoke.
Observe all safety instructions and
precautions when handling automotive
batteries.
