with limitations, or not at all .This coul daffect,
for example, the power steering and the brake
boosting effect. You wil lrequire considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignitio nwhile driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and caus eafire
Rlose its hold function.
There is arisk of fire and an accident. Release
the parking brake full ybefore driving off.
!Do not war mupthe engine with the vehicle
stationary. Drive off immediately. Avoid high
engine speeds and driving at full throttle until
the engine has reache dits operating temper-
ature.
Only shift the automatic transmission to the
desired drive position when the vehicleiss ta-

General notes
When you insert the Start/Stop button into the
ignitio nlock, the system needs approximately
two seconds recognitio ntime. You can then use
the Start/Stop button.
Pressing the Start/Stop button severalt imes in
succession corresponds to the different key
positions in the ignitio nlock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedala nd press the
Start/Stop button, the engine starts immedi-
ately.
Ac heck which periodically establishe saradio
connection between the vehiclea nd the Smart-
Key determines whethe ravalidS martKey is in
