properly, please observe the following:
R Keep the air intake grill free from

impaired. Impaired visibility could
endanger yourself and others. This may
prevent you from observing the traffic
conditions, thereby causing an accident.

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
automatically deactivated after
approximately 10 minutes of operation.

Air recirculation mode*
Switch to air recirculation mode 13
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.
GWarning!
When the air recirculation mode is
switched on, windows can fog on the inside
immediately. Fogged windows impair
visibility, endangering you and others. If
the windows begin to fog on the inside,
switching off the air recirculation mode
immediately should clear interior window
fogging. If interior window fogging
persists, make sure the air conditioning is
switched on, turn air distribution control

Loading and storing
Cup holder
GWarning!
In order to help prevent spilling liquids
on vehicle occupants and/or vehicle
equipment, only use containers that fit
into the cup holder. Use lids on open
containers and do not fill containers to a
height where the contents, especially hot
liquids, could spill during braking,
vehicle maneuvers, or an accident. Liquids
spilled on vehicle occupants may cause
serious personal injury. Liquids spilled
on vehicle equipment may cause damage not
covered by the smart Limited Warranty.
Keep in mind that objects placed in a cup
holder may come loose during braking,
vehicle maneuvers, or an accident and be
thrown around in the vehicle interior.
Objects thrown around in the vehicle
interior may cause an accident and/or
serious personal injury.
The cup holder can be used to safely store
sealed drink bottles, containers with a lid,
or beverage cans.
! Do not use the cup holder as an ashtray.
Otherwise it could be damaged.

tire pressure loss and damage to the tire
beads.
R If vehicle is heavily loaded, check tire
inflation pressure and correct as
required.
R Do not allow your tires to wear down too
far. Adhesion properties on wet roads are
sharply reduced at tread depths of less
than 1
/ 8 in (3 mm).
Recommended tire inflation pressure
GWarning!
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel
economy, and are more likely to fail from
being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
Your vehicle is equipped with the Tire and
Loading Information placard located on
the driver’s door B‑pillar ( Y page 120).
The tire inflation pressure should be
checked regularly. Only adjust the tire
inflation pressure on cold tires. The tires
can be considered cold if the vehicle has
been parked for at least 3 hours or driven
less than 1 mile (1.6 km). Depending on the
ambient temperature, the driving speed
and the tire load, the tire temperature
changes. When the tire temperature
changes by 18 ¦ (10 ¥), the tire inflation
pressure will change by approximately
1.5 psi (0.1 bar). Keep this in mind when
checking tire inflation pressure on warm
tires and adjust the tire pressure only if
the tire inflation pressure is too low for
the current operating conditions. If you
check the tire inflation pressure when the
tires are warm, the reading will be higher
than the cold reading. This is normal. Do
not let air out to match the specified cold
tire inflation pressure. Otherwise, the
tire will be underinflated.
Follow recommended cold tire inflation
pressures listed on Tire and Loading
Information placard on the driver’s door
B‑pillar.
Keeping the tires properly inflated
provides the best handling, tread life and
riding comfort.
In addition to the Tire and Loading
Information placard on the driver’s door
B‑pillar, also consult the tire inflation
pressure label (if available) on the inside
of the filler flap for any additional
information pertaining to special driving
situations. For more information, see
“Important notes on tire inflation
pressure” ( Y page 116).
i Data shown on Tire and Loading

result in handling or steering problems, or
brake failure.
Check the tire inflation pressure at least
once a month.
Check and adjust the tire inflation
pressure when the tires are cold
( Y page 115).
Checking tire inflation pressure
manually
Follow the steps below to achieve correct
tire inflation pressure:
XRemove the cap from the valve on one tire.XFirmly press a tire gauge onto the valve.XRead the tire inflation pressure on tire
gauge and check against the
recommended tire inflation pressure on
the Tire and Loading Information
placard on the driver’s door B‑pillar
( Y page 120). If necessary, add air to
achieve the recommended tire inflation
pressure.XIf you have overfilled the tire, release
tire inflation pressure by pushing the
metal stem of the valve with e.g. a tip of
a pen. Then recheck the tire inflation
pressure with the tire gauge.XInstall the valve cap.XRepeat this procedure for each tire.Tire Pressure Monitoring System
(TPMS)*
Your vehicle may be equipped with a Tire
Pressure Monitoring System (TPMS).
It monitors the tire inflation pressure in
all four tires. A warning is issued to alert
you to a decrease in pressure in one or more
of the tires.
The Tire Pressure Monitoring System
(TPMS) is equipped with a combination low
tire pressure/TPMS malfunction telltale in
the instrument cluster. Depending on how
the telltale illuminates, it indicates a low
tire pressure condition or a malfunction in
the TPMS system itself:
R If the telltale illuminates continuously,
one or more of your tires is significantly
underinflated. There is no malfunction
in the TPMS.
R If the telltale flashes for 60 seconds and
then stays illuminated, the TPMS system
itself is not operating properly.
The TPMS only functions on wheels that are
equipped with the proper electronic
sensors.
GWarning!
The TPMS does not indicate a warning for
wrongly selected inflation pressures.
Always adjust tire inflation pressure
according to the Tire and Loading
Information placard on the driver’s door
B‑pillar.
The TPMS is not able to issue a warning due
to a sudden dramatic loss of pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by
carefully applying the brakes and avoiding
abrupt steering maneuvers.
GWarning!
Each tire should be checked monthly when
cold and inflated to the inflation pressure
recommended by the vehicle manufacturer
on the Tire and Loading Information
