G
WARNING
Never drive with iced up or fogged win-
dows. Visibility will be significantly
impaired. Impaired visibility could
endanger yourself and others. This may
prevent you from observing the traffic con-
ditions, thereby causing an accident.
The best defrosting of windows is achieved
if the ice is completely removed from the
windows manually with an ice scraper
before driving off.
Also use the "Air conditioning before
start" function (Y page 90).
Control panel (Y page 101).
X Switching on: Push air volume
control 0043to level 3.
X Turn air distribution control 0084to posi-
tion 0085.
X Push temperature control 0083fully up. Rear window defroster
The rear window defroster serves to de-ice
the rear window quickly and clear the view
if the rear window is fogged.
The rear window defroster uses a large
amount of power. To keep battery drain to a
minimum, switch off the rear window
defroster as soon as the rear window is
clear. The rear window defroster is auto-
matically deactivated after approximately
10 minutes of operation. X
Make sure the key is in starter switch
position 1.
X Switching on: Press rear window
defroster switch 0043.
The indicator lamp in rear window
defroster switch 0043comes on.
X Switching off: Press rear window
defroster switch 0043once more.
The indicator lamp in rear window
defroster switch 0043goes out. Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before driving
through a tunnel). This setting cuts off the
intake of outside air and recirculates the
air in the passenger compartment. G
WARNING
When the air recirculation mode is
switched on, windows can fog on the inside
immediately. Fogged windows impair vis-
ibility, endangering you and others. If the
windows begin to fog on the inside, switch-
ing off the air recirculation mode imme-
diately should clear interior window fog-
ging. If interior window fogging persists,
make sure the air conditioning is switched
on, turn air distribution control 0084to
position 0085and increase the air volume
using air volume control 0043.

High-voltage battery
Introduction
The components of the drive system are
indicated by yellow warning labels to make
you aware of high voltage.
High-voltage cables are orange-colored. G
WARNING
The drive system is subject to high vol-
tages.
You may be seriously or even fatally injured
if you:
R tamper with components or high-voltage
cables in the drive system
R touch components or high-voltage cables
in the drive system on a vehicle which has
been involved in an accident
R touch damaged drive system components
Do not remove any drive system component
covers which are marked with a warning
sticker. Do not tamper with components or
orange high-voltage drive system cables. G
WARNING
The high‑voltage battery of the drive sys-
tem is located under the vehicle’s under-
body. When the pressure inside the
high‑voltage battery exceeds a certain
value, for example in case of a vehicle fire,
inflammable gas will escape via a duct. The
inflammable gas escapes to an area under
the vehicle. This prevents the high‑voltage
battery from exploding.
Stay away from this area of the vehicle. The drive system is powered by a high-
voltage battery. The high-voltage battery
stores and releases the energy required for
operation of the electric motor.
The electric motor uses the energy that is
stored in the high-voltage battery when
driving off and when accelerating.
When rolling, kinetic energy is converted
into electrical energy by energy recovery
and stored in the high-voltage battery.
The range of the vehicle is reduced when
consumers are switched on, e.g. climate
control.
The high-voltage battery can be charged in
a voltage range from 100 V to 240 V.
The high-voltage battery can be charged
R through energy recovery while the vehi-
cle is rolling or when braking
R Level 1 charging - 110 V / 120 V -
A travel cord will be supplied with the
vehicle. This charging cable can be
plugged into commonly available
110 V / 120 V, 15 A power sources. This
charging method will take longer to
charge your vehicle than a dedicated
level 2 charging source. Therefore it is
not recommended as the primary method
of charging.
R Level 2 charging - 220 V / 240 V -
For the fastest possible charging time, a
dedicated 220 V / 240 V, 20 A circuit is
required. Local electrical code can vary
from town to town. Therefore, it is highly
recommended that this service is pro-
fessionally installed. This service
should be installed in a dry area with
easy access to the passenger side of the
vehicle. You will need to obtain a vehicle
charge connector that can be wired
directly to or plugged into the dedicated
220 V / 240 V service. Charge connectors
will be available for purchase through
your authorized electric drive smart
center.

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
