X
Screw the end of filler hose ?onto tire
valve G.
X Insert electrical plug Binto the aux-
iliary power outlet (Y page 110).
X Insert the key in the starter switch and
turn it to position 1.
i The vehicle’s 12‑volt battery is drained
by use of the electric air pump. You
should therefore keep the drive system
running while inflating the tire. X
Press Ion electric air pump switch C.
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.
X Let the electric air pump inflate the tire
for a maximum of ten minutes.
Pressure gauge ;must display at least
180 kPa (1.8 bar, 26 psi). !
Do not operate the electric air pump
longer than ten minutes without inter-
ruption. Otherwise it may overheat.
You may operate the electrical air pump
again after it has cooled off.
X If a tire inflation pressure of at least
180 kPa (1.8 bar, 26 psi) is not attained,
turn off the electric air pump by press-
ing 0on electric air pump switch C.
X Unscrew the end of filler hose ?from
tire valve G.
X After clearing the area around the vehi-
cle of people and obstacles, drive vehi-
cle back or forth very slowly approx-
imately 30 ft (10 m).
This serves to better distribute the tire sealant material inside the tire.
X Screw the end of filler hose ?onto tire
valve G.
X Inflate the tire again. G
WARNING
If a tire inflation pressure of
180 kPa (1.8 bar, 26 psi) 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 prop-
erly seal the tire.
Do not drive the vehicle.
Contact the nearest authorized electric
drive smart center for assistance or call
Roadside Assistance.
X After attaining a tire inflation pressure
of at least 180 kPa (1.8 bar, 26 psi), press 0
on electric air pump switch C.
The electric air pump is switched off.
X Turn the key in the starter switch to
position 0.
X Unscrew the end of filler hose ?from
tire valve G.

smart center as soon as possible to
obtain a new filler hose and a new tire
sealant container.
X Bring used tire sealant materials to an
authorized electric drive smart center

every 4 years. Replacement containers
are available at any authorized electric
drive smart center. G
WARNING
After changing a tire, contact an author-
ized electric drive smart center to make
sure the bolts holding the wheel to the car
are tight enough. Otherwise, the wheels
could come off. Each bolt should be tight-
ened to a torque of 81 lb‑ft (110 Nm). Sealing a tire (Version 2)

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. G
WARNING
Do not place any metal objects on a battery.
You could otherwise cause a short circuit
and the battery’s highly flammable chemi-
cals 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 hydro-
gen gas generated by the battery, causing
serious personal injury. G
WARNING
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 When connecting the battery, always con-
nect the positive terminal first, fol-
lowed by the negative terminal.
R Do not loosen or disconnect the battery
terminal clips while the drive system is
running or the key is in the starter
switch.
! Never loosen or detach battery terminal
clamps while the drive system is running or the key is in the starter switch. Oth-
erwise, electronic components could be
severely damaged.
Have the battery checked regularly at an
authorized electric drive smart center. Refer to Maintenance Booklet for main-
tenance intervals or contact an author-
ized electric drive smart center for fur-
ther information.
! Never invert the terminal connections! Notes on the high‑voltage battery
Have work on the high-voltage battery per- formed by an authorized electric drive
smart center only. Observe the safety noteson (Y page 16) as well as the notes on the 12-
volt battery (Y page 197). G
WARNING
The electrolyte of the high-voltage bat-
tery, i.e. the battery fluid, is toxic and
caustic. Do not allow this fluid to come in
contact with eyes, skin or clothing, for
example in case of an accident.
In case it does, immediately flush affected area with water and seek medical help
immediately.
The high-voltage battery is located in the
vehicle underbody. Keep this in mind when
jacking up the vehicle. The vehicle has
designated take-up brackets for the jack.
For more information, see (Y page 196).
! Only position the jack on the designa-
ted take-up brackets.
You must not position the jack under the
high-voltage battery. Otherwise, the
high-voltage battery could be damaged. 198

ther gas is being discharged by the bat-
teries.
Only charge the battery in a well ventilated area.
There is a risk of acid burns during the
charging procedure due to the gases which
escape from the battery. Do not lean over
the battery when it is being charged. G
WARNING
Never charge a battery while still installed in the vehicle. Gases may escape during
charging and cause explosions that may
result in paint damage, corrosion or per-
sonal injury.
X Charge battery in accordance with the
instructions of the battery charger man-
ufacturer.
! Only use chargers of a correct and suit-
able voltage.
! Never attempt to recharge a frozen bat-
tery. Have the battery checked at a smart center. The battery housing could be
damaged.
Reinstalling the 12-volt battery X
Reinstall the charged battery. Follow the
previously described steps in reverse
order.
! The battery, its filler caps and the ven-
tilation hose must always be securely
installed when the vehicle is in opera-
tion.
Reconnecting the 12-volt battery !
Always connect the battery in the order
described below. Otherwise the vehi-
cle’s electronics can be damaged.
X Turn off all electrical accessories.
X Remove the key from the starter switch.
! Never invert the terminal connections! X
Connect the battery positive lead and
fasten cover ?(Ypage 199).
X Connect battery negative lead =
(Y page 199).
i After battery power (e.g. due to recon-
nection) was interrupted, you will have
to set the clock (Y page 94).
i Have the battery’s charge status and
acid level checked at the start of the cold
season at a an authorized electric drive
smart center. Jump starting

WARNING
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 per-
sonal injury.
Read all instructions before proceeding.
! Do not tow‑start vehicle. It is not pos-
sible to tow-start the vehicle. Attempt-
ing to do so may seriously damage the
drivetrain which would not be covered by the smart Limited Warranty.
