temporarily . After
starting a cold engine, there may be a brief period of increased
noise because the oil pressure must first build up in the hydraulic
valve adjusters . This is normal and not a cause for concern .
If the engine should not start immediately, the starting process is
automatically stopped after a short time. Repeat starting procedure.

The parking brake is designed to prevent the vehicle from rol ling
unintentio nally and rep laces t he ha nd b rake.
In addit ion to the normal functions of a traditional hand brake, the
elect romecha nica l par kin g brake provides various convenience and
safety functions .
When starting from rest
• The integral start ing assist helps you when driving by automat i­
cally re leas ing the parking bra ke =>
page 11 7, "Starting from res t".
• When starting on inclines, the sta rting assist prevents the vehicle
from uninten tionally ro llin g back. The br aking f orce of the par king
brake is not released unti l suff icient dr iving force has been built up at
t he whee ls.

& WARNING
If a gear or a drive range (automatic transmission) is engaged
with the vehicle stationar y and the engine running , you mu st
in no
instance ac celerate or release the clutch carelessly . Otherwise the
vehicle will start to move immediately -risk of an accident.
0 Note

[ i ] Tips
• You can app ly the pa rking brake at any time -even wi th t he ig ni ­
t ion turned off . T he ign ition must be turned on i n order to release the
park ing b rake .
• Occas ional noises when the parking brake is applied and released
are normal and a re not a ca use fo r concern.
• When the ve hicle is parked, the parking brake goes through a self­
t e st cy cl e a t regu lar inte rvals . Any a ssoci ate d noises are normal. •
Parking
Various rules apply to prevent t he parked v ehicle from
rolling away accidentally.
Parking
- Sto p the v ehicle wi th t he foot brak e.

& WARNING
• When you leave your vehicle -even if only briefly -always
remove the ignition key . Thi s applies particularly when children
remain in the vehicle. Otherwise the children could start the
engine , release the parking brake or operate electrical equipment
( e .g. power window s) . There is the risk of an accident.
• When the vehicle is lo cked, no one -particularly not children
should remain in the vehicle . Locked doors make it more difficult
for emergency workers to get into the vehicle -putting lives at
risk. •

cator ligh t
CRUISE (US model)/ 0" (C anadia n mo del) w ill also light up
in the instrume nt cluster .
The speed is kept constant by modifying engine power or through an
active brake intervention.
& WARNING
• Always pay attention to the traffic around you when the cruise
control is in operation . You are always responsible for your speed
and the distance between your vehicle and other vehicles.
• For reasons of safety, cruise control should not be used in the
city, in stop-and-go traffic, on twisting roads and when road
conditions are poor (such as ice, fog , gravel, heavy rain and hydro­
planing) -you could have an accident.
• Switch the cruise control off temporarily when driving in
turning lanes, highway exits or in construction zones.
• Please note that unconsciously "resting" your foot on the
accelerator pedal causes cruise control not to brake. This is due to
the control system being overridden by the driver's acceleration.
(I) Tips
• Vehicles with manual transmission: You can attain the set speed
only if the gear that is currently engaged will allow it, or if it does not
tax the engine and allows it to run smoothly. Therefore shift into a
hig her o r lower gear in a t imely manne r.
• The brake lights illuminate as soon as the brakes apply
automatically .•
Changing speed
- Press the lever in the direction of the 0 => page 119,
fig. 110 or in the dire ction of the Oto increase or
decrease your speed . -
Let go of the lever to save that speed.
Change speed in increments of 1 mph (1 km/h) by lightly pressing the
lever. If you keep the lever pressed down, you will alter your speed in
S mph
(10 km/h) increments.
You can also press the accelerator pedal down to increase your speed,
e.g. if you want to pass someone. The speed you saved earlier will
resume as soon as you let off of the accelerator pedal.
If, however, you exceed your saved speed by 5 mph
(10 km/h) for
longer than 5 minutes, the cruise control will be turned off tempo­
rarily. The green symbol in the d isp lay turns white, the saved speed is
reta ined. •
Pre-selecting speed
You can pre -select your desired speed while the vehicle is
not moving.
- Turn on the ign ition .
- Pull lever into position 1
:::> page 119, fig. 110.
- Press the lever in the
0 or O direction to increase or
decrease your speed.
- Let go of the lever to save that speed.
This function makes it possible, for example, to save the speed you
want before dr iv ing on the highway. Once on the highway, activate

Engine speed !
The text message Engine speed ! appears in vehicles with manual
transmission when the driver did not shift up or down in time while
using adaptive cruise control braking or accelerating, causing the
vehicle to exceed or not reach the permitted limit speed. This causes
adaptive cruise control to deactivate automatically. A chime sounds
as a reminder .
Parking brake!
The text message Parking brake! appears if emergency braking was
manually initiated with the Electromechanical Parking Brake (EPB).
The adaptive cruise control is turned off . This is accompanied by a
warning tone.

The text message Stabilisation program appears if the Electronic
Stab ilizat ion Program (ESP) has inter vened. In this case the adaptive
cruise control is automatically turned off. This is accompanied by a
warning tone.
Speed
The set speed in mph (Canada km/h) always appears when saving or
changing the speed in adaptive cruise control~
page 125, "How is
the speed stored?" and~
page 125, "Chang ing stored speed".
Speed too low
The text message Speed too low appears if the current speed is too
low
to set or to hold the requested speed.
When setting a desired speed, it must be at least 20 mph (30 km/h).
At speeds be low 12 mph (20 km/h), the cruise control is turned off.
In speeds over 95 mph (150 km/h), the system remains active and
resumes the speed of 95 mph (150 km/h) if the driver removes the
foot from the acce lerator .

In certain situations, the braking power of the adaptive cruise control
is not sufficient to maintain an adequate distance from the object
ahead. In this situation, the adaptive cruise control calls on
you as the
driver to take action.
The
