Off , that
driver information w ill not be shown in the
display. The information will con tinue to be
calculated by the trip computer and can be
turned back
On at any t ime .
(D Tips
-This function is not avai lab le on all
vehicles.
- The driving information in the efficiency
program is also reset to zero with the
s ingle-trip memory .

In order to become familiar with the gearshift
indictor, at first just drive the way you are
used to.
If the current gear -and the d riving
situa tion -is not the best one for conse rv ing
fuel, then the indicator will display the recom­
mended gear. The disp lay shows the current
gear and the gear that is recommended
¢ fig. 12.

right of the gear currently selected if it is
recommending a higher gear .

- Down shifting:
The display will light up to
the
left of the gear currently se lected if it is
recommending a lower gear.
Somet imes the indicator will recommend
skipping a gear (3
> 5).
If there is no gearshift recommendation, then
just dr ive in the app rop riate gear for conserv­
ing fuel.
(D Note
This indicator can help you conse rve fuel.
This indica tor is not meant to show you
which gear you sho uld a lways be in in all
driving situations . Sometimes, in situa ­
tions s uch as passing, driving thro ugh
mountains or when towing a trailer, there
won't be any gearshift recommendation.
(D Tips
The display does not light up when the
clutch pedal is be ing depressed .

The eff ic iency program also has an enhanced
shift indicator . This enhanced shift indicator
follows the same concept as the "standard"
shift indicator¢
page 27. The selected and
the recommended gears are highlighted in
colo rs like a traffic light.
The color of the circle indicates if the most
suitable gear is engaged or if you should sh ift
up or down.

tions. O nly the drive r can decide which gear is correct in certain driving situations
such as when passing another vehicle,
driving on hills or towing a trailer.

Other equ ipment that is currently affecting
fuel consumpt ion is listed in the eff iciency
program. The disp lay shows up to three other
items of equipment @. T he equipment using
the most fuel is listed first. If more than three
items using fuel are switched on, the equip­
ment that is currently using the most fuel is
displayed.
A scale @also shows the current tota l con­

Starting and autom ati call y relea sing the
pa rking b rake
~ When you start to drive as usua l, the park­
ing brake is automatically re leased and your
vehicle begins to move.
When stopping at a traffic signa l or stopp ing
in city traffic on vehicles with an automatic
transmission, the parking brake can be ap­ plied. The vehicle does not have to be held
w ith the footbrake . The park ing brake elimi­
nates the tendency to creep with a drive range
engaged. As soon as you dr ive off as usual,
the park ing brake is released automatically
and the vehicle sta rts to move .
Starting on slop es
When starting on inclines, the start ing ass ist
prevents the vehicle from unintentionally roll­
ing back. The braking force of the parking
brake is not released until sufficient dr iving
force has been b uilt up at the whee ls.
(D Tips
For safety reasons, the park ing brake is re­
leased automatically only when the dr iv­
er 's safety belt is engaged in the bu ckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
~ Keep the switch@¢ page 85, fig . 98
pulled and depress the accelerator . The
park ing b rake stays app lied and p revents
the vehi cle from rolling backward.
~ You can release the switch @once you are
s u re that yo u are developing enough driving
force at the wheels by depressing the accel­ erator.
D epending on the weight of the rig (vehicle
and trai ler) and the severity of the incline, you
may roll backwards as you start. Yo u can pre­
vent roll ing backwards by holding the parking
brake switch @pulled out and accelerating -
just as you would when starting on a hill wit h
a conventional hand brake .
On the ro ad 87
Emergency braking
In the event that the conventional brake sys­
tem fails or locks .
~ In an emergency, pull the sw itch @
¢
page 85, fig. 98 and continue to pull it to
slow your vehicle down with the parking
brake .
~ As soon as you release the switch @ or ac-
celerate, the b ra ki ng process s tops.
If you pull the switch @and hold it above a
speed of about 5 mph (8 km/h), the eme rgen­
cy bra king funct ion is initia ted . T he ve hicle is
braked at all four whee ls by activating the hy­
draulic brake system. The brake performa nce
is similar to making an emergency stop¢&..
In order not to act ivate the eme rgency brak­
ing by mis take, an audib le warning tone (buz ­
zer) so unds when the switch @is pulled. As
soon as the switch @ is re leased, or the acce l­
erato r peda l is depressed, emergency braking
stops.
A WARNING
...--
Emergency braking should only be used in
an emergency, when the normal foot brake has fa iled or the brake pedal is obstructed .
Using the par king b rake to pe rform eme r­
gency brak ing will slow your vehicle down
as if you had made a full bra ke application.
The laws of physics cannot be suspended
even with ESC and its associated compo ­
nents (ABS, ASR, EDS) . In corners and
when road or weather conditions are bad,
a full brake application can ca use the vehi­
cle to sk id or the rear end to break away -
risking an accident.

_& WARNING
-Sensors have dead spaces in which ob­
jects cannot be detected. Be especially
alert for small children and animals,
since they are not always detected by the
sensors.
- The acoustic park ing system is not a sub­
st itute for the driver 's own caut ion and
alertness. U ltimate responsibi lity always
remains with the driver during parking
and simi lar maneuvers . Always watch
where you are driving.
- You should always adjust the vo lume and
frequency of the warning tones so that
yo u can easily hear the acoustic distance
warning even if the radio is p laying, the
air-cond itioner blower is on High or there
is a high level of outside noise .
- Check the settings whenever anyone else has driven the vehicle before you.
(D Note
-Remember that low obstacles for wh ich
a warn ing has already been iss ued may
"dive" below the system's sensing zone if
the veh icle is being backed up closer. In
th is case, the warn ing sound shutting off
does
not i ndicate that you have cleared
the obstacle . Instead, impact is immi­
nent.
- Objects such as trailer hitches, chains,
narrow posts or fences covered by a th in
l ayer of paint may not always be detect­
ed by the system. They can still damage
your vehicle without warning.
@ Tips
Keep the sensors in the rear bumper clean
and free of snow and ice so that the acous­
tic parking assist system can function
properly.
