Using climate control economically
Using the climate controls prudently can help save fuel.
When you use the air conditioner, engine power is reduced
and fuel consumption increases . To save fuel, you should use
the air conditioner only when necessary . Also p lease note the
following points:
- To save fuel, turn off cooling mode by pressing the
[AC)
button (indicator light goes out).
- In addition, if you open the window or the Panoramic
sliding sunroof* while driving, turn off cooling mode by
pressing the
[AC] button (indicator light goes o ut).
- If the vehic le is extremely hot due to the heat of the sun,
briefly open doors and windows.

& WARNING
If ACC initiates a braking maneuver, the brake pedal will be
retracted . Interference with the brake pedal can prevent ACC from
slowing the vehicle down and cause a crash and serious personal
injury .
• Never put anything
in the driver's footwell or let anything fall
into it. An object in the driver 's footwell can interfere with the
pedals and prevent the accelerator from being used to override
ACC or prevent ACC from being switched off when the brake pedal
is depressed and also prevent the vehicle from being slowed down
or stopped.
• Only use floor mats that keep the area around the pedals free
and that can be securely fastened to the footwell.
• Never drive with your foot underneath the brake pedal.
• Always read and heed the information and WARNINGS~
& in
" Description " on
page 134.
& WARNING
• Never rely on the distance control feature of ACC alone to
prevent rear-end collisions. Always be prepared to brake and take
evasive action to avoid collisions and other accident situations.
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to slow your vehicle safely. If closing speed is too high , you must
apply the brakes yourself to reduce the risk of a rear-end crash.

General information
The radar sensor has limits that the driver must kno w to
be a ble t o use ACC proper ly.
Th e Ad apt ive Cr uise Con trol works wi thin limi ts th at a re also rela ted
to radar sensor range and sight distance. In some situations ACC may react unus ually or late from the drive r's point of view. Therefore,
always be atte ntive to what is happe ning around you and always be
ready to interve ne, if necessary:
• when driving aro und curves ~
page 148
• when ve hicles up front are not in line wit h your vehicle

& WARNING
The radar sensor 's function and range can be reduced by rain , snow
and heavy spray . Moving vehicles up ahead may not be promptly
detected or may not be detected at all.
• Always pay careful attention to the traffic situation and be
ready to intervene and be ready to take complete control when

Automatic selector lever lock
The selector lever is locked in the P and N positions when the ignition
is turned on . To move the lever from these positions the driver must
depress the brake pedal. As a reminder to the driver, the following
warning appears in the instrument cluster display when the selector
is in
P and N:
When stationary apply foot brake while selecting gear
A time delay element prevents the selector lever from locking when
it is moved through the
N position (going from R to D). The locking
element will lock the selector lever if the lever is left in N (Neutral) for
more than approximately 1 second, without the brake pedal being
pressed .
At speeds above about 3 mph (5 km/h) the Automatic Shift Lock is
automatically deactivated in the
N position.
Interlock button
The lock button on the selector lever prevents the lever from being
accidentally shifted into ce rtain positions. Pressing this button deac
tivates the selector lever lock. Depending on the direction of the
shift, the selector lever locks at different positions . The positions are
highlighted in the illustration ~
page 163, fig. 161.
Ignition key safety interlock
The key cannot be removed from the ignition unless the selector lever
is in the
P park position . When the ignition key is removed, the
selector lever will be locked in the
P position. •
Kick-down
The kick-down feature allows the vehicle to generate
maximum acceleration.
When you press the accelerator pedal beyond the resistance point
that is reached at full throttle, the transmission will select a lower
gear ratio based on vehicle speed and engine RPM. The engine RPM
will be controlled to produce maximum vehicle acceleration as long as you continue to press the accelerator pedal beyond this
resistance
point .
& WARNING
Be careful when using the kick-down feature on slippery roads.
Rapid acceleration may cause the vehicle to skid. •
Dynamic shift program (DSP)
The automatic transmission is electronically controlled.
The transmission is self adapting and will automatically select the
best shift program suited to the driving conditions and driving style.
The transmission will select one of the
economy programs when you
drive at a steady speed or a gradually changing speed without heavy
acceleration . This achieves optimum fuel efficiency, with early
upshifting and delayed downshifting.
The transmission will automatically select the
sporty shift programs
when you drive at higher speeds, or with heavy acceleration and
frequently changing speeds. Upshifts are delayed to make full use of
engine power . Downshifting takes place at higher engine speeds than
in the economy programs.
The selection of the most suitable shift program is a continuous ,
automatic process. The driver can also make the transmission switch
to a sporty program by
quickly pressing down the gas pedal.
This causes the transmission to shift down to a lower gear to achieve rapid acceleration, e .g. for quickly passing another vehicle. You do
not need to press the gas pedal into the kick -down range . After the
transmission has upshifted, the original program is selected
according to your driving style.
An additional shift program allows the automatic transmission to
select the proper gear for uphill and downhill gradients.
This keeps the transmission from shifting up and down unnecessarily
on hills. The transmission will shift down to a lower gear when the .,_
