Indicated temperatures just above the
freezing point do not guarantee that the
road surface is free of ice. The road may
still be icy, especially in wooded areas or
on bridges. Your vehicle could start to skid
if you do not adjust your driving style
accordingly.
Therefore, always adjust your driving style
to the prevailing road and weather
conditions.
Freeze warning (Canada vehicles only)
When the outside temperature falls below
3 ¥ , the multifunction display makes you
aware of the fact that the road may be icy.
An additional freeze warning, i.e. an ice
crystal symbol, in the multifunction
display flashes. After 60 seconds, the
freeze warning stops flashing but
continues to be displayed. When the
outside temperature rises above 3 ¥, the
freeze warning goes out.
Fuel level display
Example illustration (U.S. vehicles)
The fuel level display shows the tank’s fuel
level with the aid of eight segments. The
number of dark segments indicates the fuel
level in the tank. If all eight segments are
dark, the tank is full.
You are driving on reserve fuel if there are
no more than 1.0 US gal (3.78 l) of fuel in the
tank.
If this occurs,
R the fuel pump symbol in the fuel level
display flashes
R the reserve fuel indicator shows the fuel
level in the tank in 0.1 US gal (0.5 l)
increments

GWarning!
In order to avoid distraction which could
lead to an accident, the driver should enter
system settings with the vehicle at a
standstill and operate the system only when
road and traffic conditions permit. Always
pay full attention to traffic conditions
first before operating system controls
while driving.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
GWarning!
Always select a volume that allows you to
still hear ambient sound in your immediate
vicinity (e.g. horns, emergency rescue
vehicles, police vehicles, etc.). You could
otherwise cause an accident.
GWarning!
If you wish to have a radio other than an
original smart radio fitted in your
vehicle, please always have the necessary
work performed at an authorized smart
center.
This is particularly important if your
vehicle is fitted with a radio
preinstallation. Improper connection can
result in the failure of important vehicle
functions, thereby endangering the
operating safety of your vehicle and thus
your own safety and that of other people.

Notes on HVAC
GWarning!
Follow the recommended settings for
heating and cooling given on the following
pages. Otherwise the windows could fog up,
impairing visibility and endangering you
and others.
Air conditioning with climate control*
The air conditioning improves the level of
comfort when driving at high outside
temperatures by cooling and
dehumidifying the air.
Nearly all dust particles, pollutants, are
filtered out by an integrated particle
filter before outside air enters the
passenger compartment through the air
distribution system. It also operates when

the air conditioning is switched off and
you have switched on the blower.
The air conditioning only works when the
engine is running and the blower is
switched on. Maximum effectiveness is
achieved if you drive with the windows

passenger compartment for a short
period of time before utilizing the air
conditioning.

This may cause burns or frostbite on
unprotected skin in the immediate area of
the air vents. Always keep sufficient
distance between unprotected parts of the

air distribution control to direct the air
to air vents in the vehicle interior that are
not in the immediate area of unprotected
skin.
To make sure the heating or air
conditioning with climate control* works
properly, please observe the following:
R Keep the air intake grill free from
deposits, e.g. ice or snow, to ensure that
fresh air can flow freely into the vehicle
interior.
R Do not obstruct air vents or ventilation
