2. This device must be able to
accommodate interference that is
received, including interference which
could cause unwanted functions.
Unapproved modifications to this device
may lead to withdrawal of permissio
nto
operate it.
The product label with FCC ID and IC
certification number can be found in the
battery case of the SmartKey.
Important information for using
KEYLESS-GO R
You can use the KEYLESS-GO key as a
conventional key.
R You can combine KEYLESS-GO functions
with those of a conventional key, e.g. open
with KEYLESS-GO and close with the
& button.
R Always carry your KEYLESS-GO key on your
person.
R Never keep the KEYLESS-GO key with:
-electronic equipment, such as your
mobile phone or another key
- metal objects, such as coins or metal foil
This may impair the functioning of
KEYLESS-GO.
R To open or close the vehicle, the KEYLESS-
GO key should be no more than 3 ft (1 m)
from the door or trunk.
R If the vehicle is parked for more than
72 hours, the KEYLESS-GO function is
deactivated. Pull one of the outer door
handles and turn on the ignition to
reactivate the KEYLESS-GO function.
R When the KEYLESS-GO key is removed
from the vehicle, it is possible that the
system may not recognize it. In this case,
the vehicle cannot be locked or started with
KEYLESS-GO.
R If the KEYLESS-GO key has been removed
from the vehicle, e.g. if a passenger leaves
the vehicle with the KEYLESS-GO key:
- while someone is holding the Start/Stop
button or attempting to lock the vehicle using the outer door handle, the
Key Not Detected message will appear in
the multifunction display.
- while the engine is running, the red Key Not Detected message will appear in
the multifunction display as you pull
away. Find the KEYLESS-GO key and
change its position in the vehicle. Place
the KEYLESS-GO key in a location such
as the front-passenger seat, or carry it in
your shirt pocket.
R If you have started the engine using the
Start/Stop button, you can turn if off again
by:
-pressing the Start/Stop button again
- inserting the KEYLESS-GO key into the
ignition lock when the vehicle is
stationary and the automatic
transmission is in parking position P.
R You may accidentally unlock the vehicle if
the KEYLESS-GO key is within 3 ft (1 m) of
the vehicle and:
- a jet of water splashes an outer door
handle
or
- you are cleaning an outer door handle.
R Note that the engine can be started by any
vehicle occupant if a KEYLESS-GO key is in
the vehicle.
Option 1: there is a KEYLESS-GO key in the
vehicle and a KEYLESS-GO key outside the
vehicle. If you leave the KEYLESS-GO key
behind when you get out and lock the
vehicle, a message does not appear in the
multifunction display.
Option 2: there is a KEYLESS-GO key in the
vehicle but no KEYLESS-GO key outside the
vehicle. When you get out and try to lock
the vehicle, the Key Detected in Vehicle message appears in the
multifunction display .The vehicle is not
locked in this case.
When starting the engine and while driving,
KEYLESS-GO also checksw hether a valid key76

Problems with the transmission
Problem Possible causes/consequences and
M Solutions
The transmission has
problems shifting gear. The transmission is losing oil.
X
Have the transmission checked at a qualified specialist
workshop immediately. The acceleration ability
is deteriorating.
The transmission no
longer changes gear. The transmission is in emergency mode.
It is only possible to shift into
secondgear and reverse gear.
X Stop the vehicle.
X Shift the transmission to position P.
X Switch off the engine.
X Wait at least 10seconds before restarting the engine.
X Shift the transmission to position Dor R.
If D is selected, the transmission shifts into secondgear; ifRis
selected, the transmission shifts into reverse gear.
X Have the transmission checked at a qualified specialist
workshop immediately. Transfer case
This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always
transmitted to both axles.
! Performance tests may only be carried
out on a 2-axle dynamometer. The brake
system or transfer case could otherwise be
damaged. Contact a qualified specialist
workshop for a performance test.
! To prevent ESP ®
from intervening, the
ignition must be switched off (SmartKey or
the Start/Stop button in position 0or 1) if:
R the electric parking brake is being tested
on a brake dynamometer.
R the vehicle is being towed with only one
axle raised (not permitted for vehicles
with 4MATIC).
The brake system could otherwise be
damaged.
! Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised,
as doing so will damage the transmission. Refueling
Important safety notes
G
WARNING
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flames or smoking
materials near gasoline.
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging to your
health. G
WARNING
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gasoline
to spray back out when removing the fuel
pump nozzle, which could cause personal
injury. 286
