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 notes
on (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 desig-
nated take-up brackets.
You must not position the jack under the
high-voltage battery. Otherwise, the
high-voltage battery could be damaged. 198

Charging the 12-volt battery G
WARNING
Avoid creating sparks when charging the
battery as escaping gases are flammable.
Keep open flames away from the battery and
do not smoke.
Do not touch the battery terminal with metal
objects and do not remove the battery
charger’s terminal clamps until the battery
charger has been switched off and no fur- Batteries

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

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.
