ralnotes
Vehicle swith KEYLESS- GOare equi pped with
a SmartKey featuringanintegrated KEYLESS-
GO start function andadetachab leStart/St op
button.
The Start/St opbutton mustbeinserted inthe
ignition lockandtheSmartKey mustbeinthe
vehicle .
When youinsert theStart/St opbutton into
the ignition lock,thesystem needsapprox-
imatel ytwo seconds recognition time.Youcan
then usetheStart/St opbutton.
Pressing theStart/St opbutton several times
in successio ncorresponds tothe different keypositio
nsinthe ignition lock.Thisisonly the
case ifyou arenot depres singthebrake pedal.
If you depres sthe brake pedaland press the
Start/St opbutton, theengine startsimmedi -
ately .
A check whichperiodicallyestabl ishesaradi o
connection betweenthe vehicle andthe
SmartKey determines whetheravali dSmart-
Key isin the vehicle .This occurs, forexample ,
when starting theengine.
To start thevehicle withoutactively usingthe
SmartKey:
R the Start/St opbutton mustbeinserted in
the ignition lock.
R the SmartKey mustbeinthe vehicle .
R the vehicle mustnotbelocked withthe
SmartKey orKEYLESS- GO(Ypage 66).
Do not keep theSmartKey:
R with electronic devices,e.g.amobil ephone
or another SmartKey.
R with metall icobjects, e.g.coins ormetal
foil.
R inside metallicobjects, e.g.ametal case.
This canimpa irthe functionality ofthe KEY-
LESS- GOkey.
If you lock thevehicle withtheSmartKey's
remote controlorwith KEYLESS- GO,after a
short time:
R you willnot beableto switch onthe ignition
with theStart/St opbutton.
R you willnot beableto start theengine with
the Start/St opbutton untilthevehicle is
unlocked again.
The engine canbeswitched offwhil ethe vehi-
