2016 SMART FORTWO key locked in ignition

Pets in the vehicle
GWARNING
If you leave animals unattended or unse-
cured in the vehicle, they could press but-
tons or switches, for example.
As a result, they could:
Ractivate vehicle equipment and become
trapped, for example
Ractivate or deactivate systems, thereby
endangering other road users
Unsecured animals could also be flung
around the vehicle in the event of an acci- dent or sudden steering or braking, thereby
injuring vehicle occupants. There is a risk
of an accident and injury.
Never leave animals unattended in the
vehicle. Always secure animals properly
during the journey, e.g. use a suitable ani-
mal transport box.
Protection against theft
Immobilizer
The immobilizer prevents your vehicle from
being started without the correct Smart Key.
XTo activate: remove the Smart Key from the
ignition lock.
XTo deactivate: switch on the ignition.
When leaving the vehicle, always take the
Smart Key with you and lock the vehicle. The
engine can be started by anyone with a valid

In the event that the engine cannot be star-
ted when the starter battery is fully
charged, the immobilizer may be faulty.

Important safety notes
GWARNING
Combustion engines emit poisonous
exhaust gases such as carbon monoxide. If
the tailgate is open when the engine is
running, particularly if the vehicle is
moving, exhaust fumes could enter the
passenger compartment. There is a risk of
poisoning.
Turn off the engine before opening the
tailgate. Never drive with the tailgate
open.
GWARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could
slip, tip over or be flung around and
thereby hit vehicle occupants. There is a
risk of injury, particularly in the event of
sudden braking or a sudden change in
direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before
the journey.
!Do not exceed the lower tailgate maximum
load of 220 lbs (100 kg). It may otherwise
become damaged.
!The tailgates swings backwards, upwards
and downwards when opened. Therefore,
make sure that there is sufficient space
above, behind and under the tailgates.
iThe opening dimensions of the tailgate
can be found in the "Vehicle data" section
(
Ypage 212).
Preferably stow luggage or loads in the lug-
gage compartment. Observe the loading
guidelines (
Ypage 142).
Do not leave the SmartKey in the cargo com-
partment. You could otherwise lock yourself
out.

Side window reversing feature
In vehicles with the convenience feature, theside windows are equipped with an automatic
reversing feature. If a solid object blocks or
restricts a side window from traveling
upwards during the automatic closing proc-
ess, the side window opens again automati-
cally. During the manual closing process, the side window only opens again automatically
after the corresponding switch is released.
The automatic reversing feature is only an
aid and is no substitute for your attention
when closing a side window.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small
fingers
Rwhile resetting
This means that the reversing feature can-
not prevent someone being trapped in these
situations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure. If
someone becomes trapped, press the switch
to open the side window again.
GWARNING
If you close a side window again immedi-
ately after it has been blocked or reset, the
side window closes with increased or max-
imum force. The reversing feature is then
not active. Parts of the body could be trap-
ped in the closing area in the process. This
poses an increased risk of injury or even
fatal injury.
Make sure that no parts of the body are in
the closing area. To stop the closing proc- ess, release the switch or push the switch
again to reopen the side window.
Opening or closing the side windows
The switches for both side windows are loca-
ted on the driver's door. There is also a
switch for the front-passenger side window
on the front-passenger door. The switch on the driver’s door takes prece-
dence.
