General recommendations
Why is your seat adjustment so important?
The safety belts and the airbag system can only provide
maximum protection if the front seats are correctly
adjusted.
There are various ways of adjusting the front seats to provide safe and comfortable support for the driver and the front passenger.
Adjust your seat properly so that:
• you can easily and quickly reach all the switches and controls in
the instrument panel
• your body is properly supported thus reducing physical stress
and fatigue
• the safety belts and airbag system can offer maximum protec ­
tion=> page 218.
In the following sections, you will see exactly how you can best
adjust your seats.
There are special regulations and instructions for installing a child seat on the front passenger's seat. Always follow the information
regarding child safety provided
in=> page 243, "Child Safety".
& WARNING
Incorrect seating position of the driver and all other passengers
can result in serious personal injury.
• Always keep your feet on the floor when the vehicle is in motion
- never put your feet on top of the instrument panel, out of the
window or on top of the seat cushion. This applies especially to
the passengers. If your seating position is incorrect, you increase
the risk of injury in the case of sudden braking or an accident. If
& WARNING (continued)
the airbag inflates and the seating position is incorrect, this could
result in personal injury or even death.
• It is important for both the driver and front passenger to keep
a distance of at least 10 inches (25 cml between themselves and
the steering wheel and/or instrument panel. If you're sitting any
closer than this, the airbag system cannot protect you properly. In
addition, the front seats and head restraints must be adjusted to
your body height so that they can give you maximum protection.
• Always try to keep as much distance as possible between your­
self and the steering wheel or instrument panel.
• Do not adjust the driver's or front passenger's seat while the
vehicle is moving. Your seat may move unexpectedly, causing
sudden loss of vehicle control and personal injury. If you adjust
your seat while the vehicle is moving, you are out of position. •
Driver's seat
The correct seat position is important for safe and relaxed
driving.
We recommend that you adjust the driver's seat in the
following manner:
- Adjust the seat in fore and aft direction so that you can
easily push the pedals to the floor while keeping your knees slightly
bent => & in "Why is your seat adjustment
so important?".
- Adjust the seatback so that when you sit with your back
against the seatback, you can still grasp the top of the
steering wheel.

Seats and storage
Seat memory
Driver's seat memory
The seat adjustment settings for four drivers can be
stored using the memory buttons in the driver's door.
Fig. 94 Driver's door:
Seat memory
In addition to the setting for the driver's seat, the settings for the
head restraints, safety belt height, steering column and both exte­
rior mirrors can be stored .
Storing and recalling settings
Using the memory buttons 1, 2, 3 and 4, you can store and recall the
settings for four different
drivers => fig. 94.
The current settings are also automatically stored on the remote
control key being used when the vehicle is locked. When the vehicle
is unlocked, the settings stored on the remote control key being
used are automatically recalled. This function has to be activated in
MMI => page 95.
Turning seat memory on and off
If the [ ON/OFF I switch is depressed, the seat memory is inoperative.
The word
OFF next to the [ON /OFF ! switch illuminates.
All the stored settings are retained. We recommend using the
[ ON /OFF! switch and deactivating the seat memory if the vehicle is only going to be used
temporarily by a driver whose settings are not
going to be stored. •
Storing and recalling a seat position
Before you can store or recall your seat position, the
[ ON /OFF] button must be engaged (down).
Storing settings
-Adjust the driver's seat => page 87.
-Adjust the head restraint => page 91.
-Adjust the steering column => page 128.
-Adjust both outside mirrors=> page 84. In the tilt-down
position, the passenger mirror can be adjusted to the
preferred position and saved in the seat memory.
-Press the [SET] button and hold it down. At the same
time, press one of the memory buttons for at least one
second.
-Release the buttons. The settings are now stored under
the corresponding memory button.
Recalling settings
-Driver's door open - press the desired memory button .
-Driver's door closed - press the corresponding memory
button until the stored position is reached.
When the vehicle is locked, the current settings are stored and
assigned to the remote control key. But the settings stored on
memory buttons 1 to 4 are not deleted. They can be recalled at any
time. When the vehicle is
unlocked , the settings stored on the
remote control key are restored. .,_

Stopping the engine
-Turn the ignition key to position®~ page 130, fig. 145.
& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running. With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop normally, this can lead to accidents and serious injuries .
• The radiator fan can continue to run for up to 10 minutes even
after you have turned off the engine and removed the ignition key.
The radiator fan can also turn on again if the engine coolant heats
up because of intense sunlight or heat build-up in the engine
compartment.
0 Note
Do not stop the engine immediately after hard or extended driving.
Keep the engine running for approximately two minutes to prevent
excessive heat build-up.•

Adaptive Cruise Control
Speed and distance control system
Applies to vehicles : with Adaptive C ruise Cont rol
Description
The Adaptive Cruise Control driver assistance program is
a combined speed and distance control system .
Fig. 151 Front
bumper: Position of
radar sensor
Any speed between about 20 mph (30 km/h) and about 95 mph (150
km/h) can be set and held with the Adaptive Cruise Control. The
system also helps keep a distance you previously selected to vehi ­
cles ahead of you.
Adaptive Cruise Control can help reduce driving stress and fatigue
by maintaining a preset speed with automatic braking and acce ler ­
ation. Driving can be more relaxed, particularly on long trips on
interstates or on other highways that are genera lly straight.
How does it work?
A lever on the steering wheel column operates the Adaptive Cruise
Control)=> page 141, "How is the speed stored?" and=> page 143,
"How is distance set?".
Contro ls a nd eq uip­
ment
Driver information
Important information is brought up in the speedometer and in the
instrument cluster display as the vehicle is being driven
=> page 144, "Driver information".
What is important for you to know
There are limits to what Adaptive Cruise Control can do as the
vehicle is being
driven => page 149, "Special driving situations" .
LJ}. WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injury.
• Never drive at speeds that are too high for traffic, road and
weather conditions.
• Never follow the vehicle in front so closely that you cannot stop
your vehicle safely. The Adaptive Cruise Control cannot brake the
vehicle safely when you follow another vehicle too closely. Always
remember that the Adaptive Cruise Control has a braking power
that is only about 25% of the vehicle's maximum braking ability,
the automatic braking function cannot bring the vehicle to a stop.
• Never use Adaptive Cruise Control on roads where you cannot
drive safely at a steady speed, including city or stop-and -go or
heavy traffic, on winding roads or when road conditions are poor
(for example , on ice, gravel , in fog , heavy rain or on wet roads that
increase the risk of hydroplaning).
• Always turn off Adaptive Cruise Control when entering turn
lanes , highway exit lanes and construction zones or similar situa­
tions because the vehicle will automatically accelerate to the
stored speed
• Never rest your foot on the accelerator pedal, especially when
the Adaptive Cruise Control is being used because doing so will
override the braking function and prevent the brakes from being _.,
