Sys tem.
A WARNING
- Never allow the engine to ru n in confined
spaces, because this inc reases the r isk of as­
phyx iat ion.
- Never t urn off the engine before the veh icle
has come to a comp lete stop .
- The brake booster and power steer ing no
longer function whe n you stop the engine.
You must use more fo rce when bra king or
stee ring. Be cause you cannot b rake and
steer as you us ually wou ld, this could lead
to accidents and se rious i njuries. These
functions are still active if the Start-Stop­
System* has stopped the engine.
([) Note
Avoid high engine speed, fu ll th rottle , and
heavy eng ine load as lon g as the engine has
not reached operating temperature yet. You
co uld damage the engi ne .
@ For the sake of the environment
Do not let the engine r un while parked to
warm up. Beg in driving immed iately . This re­
duces u nnecessary emissions .

(D Tips
-After starting a cold engine, there may be a
br ief per iod of increased noise because the
oil pressure must first bui ld up in the hy­
draulic valve adjusters. This is normal and
not a cause for concern .
- If you leave the veh icle with the ignition
switched on, the ign ition w ill switch off af­
ter a certain amount of time . Make sure that
electrical equipment such as the exterior
l ights a re switched off.

Steering lock
The steering locks when yo u tur n the eng ine off
us ing the

I S TAR T ENGINE ST OP I button at speeds below
6 mph (10 km/h) and press the brake peda l.
A WARNING
-Never turn off the engine until the vehicle
has come to a complete stop.
- The brake booster and power steering only
work when the engine is running . If the en­
gine is off , you have to use more force when
steering or braking. Because you cannot
steer and brake as you usually wou ld, this
could lead to crashes and serio us in ju ries.
- For safety reasons, you should always pa rk
your veh icle with the selector lever in P. Oth ­
erw ise, the vehicle could inadve rtently ro ll

ment such as power windows, which in­
creases the r is k of an accident .
- No one sho uld remain in the vehicle when i t

make it more difficult for emergency wo rk­
ers to get into the vehicle, which puts lives
at risk.

{!) Tips
Fo r safety reasons, the pa rking bra ke is re­
l eased automatically only when the d river 's
safety be lt is engaged in the b uckle.
Starting to drive with a trailer
To prevent rolling bock unintentionally on on in ­
cline, do the following:
,.. Keep the sw itch pulled ~ and p ress the acce l­
erator peda l. The parking brake stays applied
and prevents the vehicle from roll ing backward .
,.. You can re lease the switch
[21 once you are s ure
that you are transferring enough drivi ng force
to the wheels by pressing the accele rato r pedal.
Depend ing on the we ight of the rig (vehicle and
trailer) and the severity of the incline, you may
ro ll backwards as you start.
Emergency braking function
This is used if the conventional broke system
fails or locks up.
,.. To brake your ve hicle in an eme rgency, pull the
[21 switc h and hold it p ulled.
,.. As soon as you release the
[21 switch or acce ler-
ate, the b rak ing stops.
If you pu ll the switch «el) and hold it above a
speed of about 5 mph (8 km/h), the emergency
braking fu nction is i nitiated. The vehicle is braked
at all four whee ls by activati ng the hydrau lic
brake system. The brake perfo rmance is s imi lar
to maki ng an emergency stop~.&. .
In order not to act ivate the emergency braking by
mistake, an aud ib le warn ing tone (buzze r)
sounds when the~ switch is pulled . As soon as
the~ switch is released, or the acce le rator pedal
is depressed, eme rgency b raking stops .
A WARNING
Emergency br aking should only be used in an
emergen cy, when t he norma l brake ped al has
failed or the bra ke peda l is obstructed . Us ing
the parking brake to perfo rm emergency brak-
-
ing will slow yo ur vehicle down as if you had ~

Fig. 85 Instrument cluster: Eng ine stop tempora rily un­
avai lable
Engine does not switch off
Before and during each stop phase, the system
checks if certain conditions have been met . For
examp le, the engine will not switch off in the fol­
lowing situations:
- The engine has not reached the minimum re­
quired temperature for Start-Stop mode.
- The interior temperature selected by the A/C
system has not been reached.
- The outside temperature is extremely high/low.
- The windshield is being defrosted@.
- The parking system* is be switched on .
- The battery charge level is too low .
- The steering wheel is turned at a sharp angle or
is moving .
- After engaging the reverse gear.
- On sharp inclines.

play.
Engine automatically restarts
The standard Start-Stop mode will be canceled
during a stop phase in the following situations .
The engine restarts without any action by the driver.
Driving
- The vehicle rolls, for examp le while on a s lope.
- The interior temperature varies from the tem-
perature selected in the A/C system.
- The windshield is being defrosted@.
- The brake pedal is pressed severa l times in a
row.
- The battery charge level becomes too low.
- High power consumption.
The engine can turn off again when the condi­ tions for Start-Stop mode are met.
Ignition is switched off automatically
To prevent the battery from draining, the igni­
tion
will switch off automatically under the fol­
lowing conditions:
- The vehicle has already been driven.
- The Start-Stop-System has stopped the engine.
- The driver's door is opened .
- The driver's safety belt is removed.
- The brake pedal is not pressed down.
- The vehicle is stationary.
In this case, the activated low beam is replaced
by the parking light. The parking lights will
switch off after approximately 30 minutes or
when you lock the vehicle.
If the Start-Stop-System has not turned off the
engine or if you have switched the Start-Stop­
System off manually, the ignition will not be au­
tomatically switched off and the engine will con­
tinue to run

Speed warning system
Introduction
The speed warning system helps you to stay un­
der a specified maximum speed .
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
You w ill hear a warning tone when your speed ex ­
ceeds the sto red val ue by app rox imately 3 mph
(3 km/h) . An indicator light . (USA mode ls)/ .
(Ca nada models) in the ins trumen t cluste r dis­
play a lso turns o n at the same time. The ind ic a tor
li ght .,. turns off w hen the speed decrea ses
below the stored maximum speed.
Set ting a t hreshol d is recom mended if you would
lik e to be rem inded when you re ach a cert ain
maximum speed . Si tua tions where you may want
to do so include drivin g in a country w ith a gene r­
a l speed limit or if there is a specified max imum
speed for winter tires.
(D Tips
Eve n though your vehicle is eq uipped w ith a
speed warning system, you should still watch
the speedometer to make sure yo u are not
drivi ng faster than the speed lim it.
Setting the threshold
You con set , change and delete the warning
threshold in the Infotainment system.
• Select: the ICAR I function button > (Car)* Sy s­

The stored speed and the indicator light

in the instrument cluster display
c:> fig. 88. The
display may vary, depending on the type of dis­
play in your vehicle.
This informat ion is also shown briefly in the
Head-up display*.
The speed is kept constant by modifying engine power or through an active brake intervention.
A WARNING
- Always pay attention to the traffic around
you when the cruise control is in operation.
You are always responsib le for your speed
-
Dr ivi ng
and the distance between your vehicle and
other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road cond itions are
poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because this increases the
risk of an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, h ighway ex its
or in construction zones.
- Please note that unconsciously "resting" your foot on the accele rator pedal p revents
the cruise control from braki ng. This is d ue
to the contro l system being over ridden by
the dr iver's acceler ation.
- I f a brake system malfunction such as over­
hea ting occurs when the cruise cont ro l sys­
tem is swit ched on, the braking f unction in
the system may be switched off. The rest o f
the cruise co ntrol system f unctions remain
active as long as the indicator light
