Important notes on using KEYLESS-GO*

You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(
page 112).
The starter switch is located under the
KEYLESS-GO button. Pull the
KEYLESS-GO button out in order to ac-
cess the starter switch (
page 43).

You can combine KEYLESS-GO func-
tions with normal SmartKey functions
(e.g. unlocking with KEYLESS-GO and
locking with the ‹button).

Always carry the SmartKey with
KEYLESS-GO with you.

Never store the SmartKey with
KEYLESS-GO together with:

electronic items such as a cellular
phone or another SmartKey with
KEYLESS-GO

metallic objects such as coins or
metal foil
Doing so could impair the function of
the KEYLESS-GO system.

To lock or unlock the vehicle, the
SmartKey with KEYLESS-GO must be
located outside the vehicle within ap-
proximately 3 ft (1 m) of the respective
door or the tailgate.

If the vehicle has been parked for more
than 72 hours, you must pull an outside
door handle in order to activate the
KEYLESS-GO function.

must be located in the vehicle.

must be inserted in the starter
switch (
page 43).

The brake pedal must be firmly
depressed. Do not depress the
accelerator.

If the SmartKey with KEYLESS-GO is
positioned farther away from the vehi-
cle, the system may no longer recog-
nize the SmartKey with KEYLESS-GO.
The vehicle then cannot be locked or
the engine started via the KEYLESS-GO
system.

If you have started the engine with the
KEYLESS-GO start/stop button
(
page 57), you can turn it off again by

pressing the KEYLESS-GO
start/stop button (
page 69)

inserting the SmartKey into the
