The detection~ page 146, fig. 161 of the radar sensor detection
area is made up of :
• the approach area (light green area)
(D, about 230 feet (70 m)
behind the vehicle, and
• the "blind spot" (dark green area)@.
The radar sensors cover the adjacent left and right lanes. Other lanes are
not cove red by the radar sensors.
rn Tip s
Side assist does not measure act ual lane width. The system assumes
a fixed lane w idth. Detection in the left and right lanes is based on
this assumed lane w idth. When driving on narrow roads or when
driving to the left or right of the center of a travel lane, it is possible
that vehicles will be detected that are
not in the lane next to the lane
you are using~
page 151. •
Applie s to ve hicl es: w ith s id e a ssist
Operation
Side assist compares the distance and difference in speed of detected
vehicles with the speed of your vehicle . Whenever the difference in
speed and distance is registered as notab le if you were to change
lanes, a signa l light appears on the respect ive m irror .
The signa l can light up if you are passed by a vehicle or if you are
passing another vehicle.
If you pass another vehicle slowly (d ifference in speed less than 9
mph, or 15 km/h) , the signa l light will come on as soon as the other
vehicle is in your blind spot and is detected by side ass ist . When the
difference in speed is greater, the signal light wi ll not come on. •

Informational and alert stage signals
S ide assis t has two signa l st ages:
• the informational stage signal, and
• t he ale rt stage signal.
S ide assist helps you by using the appropr iate s ignal stage,
depending on whether or not you have activated the turn signal, and
thus have indicated that you are or are not changing lanes .
Informat ional stage signal
As long as you have not activated the turn signal, side assist informs
you of detected vehicles that are registered as being in a notable loca­
tion if you were to change lanes . Wheneve r the detected vehicle 's
difference in speed and distance is registered by side assist as
notable, the signal l ight on the respective m irror produces muted
illumination .
Th e br ightness of the info rmationa l stage signal is designed no t to be
as intense, so that it does not interfere w ith your v iew of the road
when you are driving and have no in tention of chang ing lanes. When
you look in the outside mirror, you can clearly see the informat ional
stage signal.
Alert stage signal
Whe n you act ivate the tu rn s ignal, a nd side assist has de tected a
vehicle in a notable location on that particular side, the signal light on
this side mirro r flashes b rightly. The repeated brief and bright
flash ing of the alert stage signal reminds you to carefully check
traffic to the rear in the outside mirror and over your shoulder, so t hat
you can safely complete the lane change~

CD S ignal on out sid e mirror do es n ot light up
A vehicle approach ing slow ly- in the left -hand lane for example -was
detected by the sensors . Because of the small difference in speed and
the conside rable d istance from your vehicle, the signal on the outside
mirror will not light up=>
& in "Safety tips" on page 152.
@ Informational stage signal light s up
The distance between your veh icle and that of the slowly approach ing
vehicle has narrowed. The informational stage signal on the outside
m irror lig hts up.
As soon as the difference in speed and distance is registered as
notable if you we re to change la nes, a sig nal on the m irror lights up.

your "b lind spot" .
@ Alert stage signal flashes
If you activate your tur n sign al in drivi ng situa tion @, the signa l light
briefly flashes repeatedly. Side assist is alerting you of a veh icle t hat
you may not have no tic ed.
[ i ] Tips
• T he faste r a veh icle approaches from the rear, the soone r the
signal on the outs ide mirror lights up. Side assist will signal, at the
latest, when a detected vehicle enters your "blind spot".
• When veh icles approach very quickly, chang ing lanes can be
dangerous even if the s ignal on the outside mi rror does not light up. •

General information
Side assist has limits and cannot detect vehicles under all road and
weather conditions . Please remember system limitations and n ever
re ly on the system, especially when :
• driving through curves=>
page 151,
• lanes are of different widths=> page 151. •
Ap plies to vehicles: w ith sid e assist
When driving through curves
Side assist cannot detect vehicles in curves with a turning radius of
less than 328 feet (100 m).
When driving through a curve, it is possible that side assist may
register a vehicle two lanes over, and the signal on the outside mirror
will light up.•

detect vehicles two
lanes away
Side assist's detection area is designed to cover lanes of standard
w idth to the left and rig ht of your travel lane, depending on whether
you drive in the center of your lane or closer to the edge.
If you drive in narrow lanes, side assist's detectio n area may also
include other lanes -especially if you tend to drive on t he edge of your
lane => fig. 167. Under these conditions, vehicl es can also be
detected that are two lanes away, and side assist then could switch
between the informationa l and warning stage signals .
When driving in very wide lanes, vehicles in the adjacent lane may not
be detected because they are not inside the detection area .•

_& WARNING
• Unintended vehicle movement can cause serious injury.
- When the selector lever is
in a driving position, the vehicle
may creep, even at idle speed. Therefore do not release the
parking brake or foot brake until you are ready to move,
because power is transmitted to the wheels as soon as a driving
position is engaged.
- Do not accelerate while selecting a driving position. At this
time the engine must be at idle speed so that undue stress is
not placed on the clutches in the transmission.
- Remember : · even when stopped briefly with the automatic
transmission in "D" or "R", engine power is being transmitted
to the wheels. Your vehicle could "creep " forward or backward.
When stopped, keep the brake pedal fully depressed and use
the parking brake if necessary to keep the vehicle from rolling.
• If the selector lever is unintentionally moved into N while you
are driving, take your foot off the accelerator pedal and wait for
the engine to return to idle speed before selecting a driving posi­
tion .
• Never shift into "R" or "P" when the vehicle is in motion.
• Never get out of the driver's seat when the engine is running.
• If you must get out of the vehicle , move the selector lever
securely into the P position and apply the parking brake firmly.
• If the engine must remain running, never have any driving
position engaged when checking under the hood. Make sure the
selector lever has securely engaged and is locked in "P" with the
parking brake firmly set~
page 281, "Engine compartment ".

Automatic selector lever lock
The se lector lever is locked in the P and N positions when the ignition
is turned on. To move the lever from these posit ions 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 lock ing 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 (Neutra l) for
more than approximately
l second, w ithout the brake pedal being
pressed.
At speeds above about 3 mph (5 km/h) the Automat ic Shift Lock is
automatically deactivated in the
N position.
Interlock button
The lock button o n the selector lever prevents the lever from being
accidentally shifted into certain 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 pos itions are
highlighted in the illustration ~
page 156, fig. 170.
Ignition key safety interlock
The key cannot be removed from the ignition un less 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
Controls and equip­
ment Safety first
as you cont
inue 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 sh ift p rogram su ited to the driv ing cond it ions 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 ach ieves optimum fuel efficiency, with early
upshifting and delayed downshifting.
Th e transmission will automatically select the
sporty shift programs
when you dr ive at higher speeds, or w ith 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 select ion of the most suitable shift program is a cont inuous,
automatic p rocess. The driver can also make the transmission switch
t o a spo rty program by
quickly pressing down the gas pedal.
Th is causes the transmission to shift down to a lower gear to achieve
rap id acceleration, e.g . for quickly passing another vehicle. Yo u 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 uph ill and downhill gradients.
Th is prevents the transmission from upshifting and downshifting
unnecessari ly on hills. The transmission will shift down to a lower _,.
