KEYLESS-GO start/stop button once or
twice, the 45 indicator lamp comes
on for approximately 6 seconds and then
goes out.
If the 45 indicator lamp should not
come on or is continuously lit, the system is
not functioning. You must see an authorized
Mercedes-Benz Center before seating any
child on the front passenger seat. More
information can be found in the “Practical
hints” section ( Y page 297).GWarning!
Do not place powered-on laptops, mobile
phones, electronic tags such as those used in
ski passes and like electronic devices on the
front passenger seat. Signals from such
devices may interfere with the BabySmart™
air bag deactivation system. Such signal
interference may cause the 45
indicator lamp not to come on during self-test.
The SRS indicator lamp 6 and/or the
45 indicator lamp could be
continuously lit, indicating that the system is
not functioning. The front passenger front air
bag could deploy inadvertently or fail to
deploy in an accident.
GWarning!
The BabySmart™ air bag deactivation system
will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart™
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness off the BabySmart™ air bag
deactivation system. The bottom of the child
seat must make full contact with the front
passenger seat cushion. An incorrectly
mounted child seat could cause injuries to the
child in case of an accident, instead of
protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
Seat belts
Safety notes
The use of seat belts and infant and child
restraint systems is required by law in all 50
states, the District of Columbia, the U.S.
territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened whenever the vehicle is in motion.
i See “Children in the vehicle”
( Y page 53) for information on
R infants and children traveling with you in
the vehicle
R restraint systems for infants and children
GWarning!
Always fasten your seat belt before driving off.
Always make sure all of your passengers are
properly restrained. You and your passengers
should always wear seat belts.
Failure to wear and properly fasten and
position your seat belt greatly increases your
risk of injuries and their likely severity in an
accident.
If you are ever in an accident, your injuries can
be considerably more severe without your
seat belt properly buckled. Without your seat
belt buckled, you are much more likely to hit
the interior of the vehicle or be ejected from
it. You can be seriously injured or killed.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. The air bags can only protect
as intended if the occupants are properly
wearing their seat belts.
GWarning!
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. That could cause serious
or even fatal injuries. The seat backrest and

iCanada only:
This device complies with RSS-210 of
Industry Canada. Operation is subject to
the following two conditions:
1. This device may not cause interference,
and
2. this device must accept any interference received, including
interference that may cause undesired
operation of the device.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
Important notes on using KEYLESS-GO
R You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
( Y page 66).
R You can combine KEYLESS-GO functions
with normal SmartKey functions (e.g.
unlocking with KEYLESS-GO and locking
with button &).
R Always carry the SmartKey with you.
R Never store the SmartKey together with
- electronic items such as a mobile phone
or another SmartKey
- metallic objects such as coins or metal
foil
Doing so could impair the function of the
KEYLESS-GO system.
R To lock or unlock the vehicle, the SmartKey
must be located outside the vehicle within
approximately 3 ft (1 m) of a door or the
tailgate.
R When the vehicle has been parked for more
than 72 hours, the KEYLESS-GO function is
deactivated. Pull an outside door handle
and switch on the ignition once to activate
the KEYLESS-GO function.
R If the SmartKey is positioned farther away
from the vehicle, the system may no longer
recognize the SmartKey. The vehicle
cannot be locked or the engine started via
the KEYLESS-GO system.
R If the SmartKey is removed from the vehicle
(e.g. if a passenger exits the vehicle with
the SmartKey)
- when pressing the KEYLESS-GO start/
stop button or trying to lock the vehicle
with the outside door handle the
message Key Not Detected appears in
the multifunction display
- with the engine running, the red message
Key Not Detected appears in the

Find the SmartKey or change its present
location immediately (e.g. place it on the
front passenger seat or insert it in shirt
pocket).
R If you have started the engine with the
KEYLESS-GO start/stop button, you can
turn it off again by
- pressing the KEYLESS-GO start/stop
button
- inserting the SmartKey into the starter
switch when the vehicle is at a standstill
and the automatic transmission is in park
position P
R The vehicle could be inadvertently
unlocked if the SmartKey is within 3 ft (1 m)
of the vehicle and
- an outside door handle is splashed with
water
or
- you attempt to clean an outside door
handle
R Remember that the engine can be started
by anyone with a SmartKey that is left
inside the vehicle.

one SmartKey outside the vehicle):
If you leave the SmartKey behind when
exiting and locking the vehicle, no message

Outside temperature indicator
The outside temperature indicator is
displayed in the multifunction display
(Y page 112).
GWarning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
Fuel gauge
The fuel gauge is on the left-hand side of the
instrument cluster (Y page 28). Once the fuel
level has fallen below the reserve mark, the
yellow fuel tank reserve warning lamp 8
for the fuel reserve comes on.
Control system
Introduction
The control system is activated as soon as the
starter switch is in position 2.
The control system enables you to call up
information about your vehicle and to change
vehicle settings.
For example, you can use the control system
to find out when your vehicle is next due for
maintenance service, to call up statistical
data on your vehicle, and much more.
GWarning!
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions permit
it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
The control system relays information to the
multifunction display.
Multifunction steering wheel
The displays in the multifunction display and
the settings in the control system are
controlled by using the buttons on the
multifunction steering wheel.

Depending on the selected menu, pressing
the buttons on the multifunction steering
wheel will alter what appears in the
multifunction display.
The information available in the multifunction
display is arranged in menus and
accompanying functions and submenus.
The individual functions are then found within
the relevant menu (radio or CD operations
under Audio, for example). These functions
serve to call up relevant information or to
customize the settings for your vehicle.
It is helpful to think of the menus, and the
functions within each menu, as being
arranged in a circular pattern.
In the Settings menu, instead of functions,
you will find a number of submenus for calling
up and changing settings. For instructions on
using these submenus, see “Settings menu”
( Y page 119).
The number of menus available in the system
depends on which optional equipment is
installed in your vehicle.
