Driving and operating189● The collision imminent brakingsystem is applying the brakes.
● The radar sensor is blocked by an ice or water film.
● A fault is detected in the radar, engine or brake system.
Additionally, the system is
automatically deactivated on vehicles
with automatic transmission (full
speed range adaptive cruise control)
when:
● The electric parking brake is applied.
● The vehicle is being held to a stop
by the system for more than
two minutes.
● The vehicle stops, the driver's seat belt is released and the
driver's door is opened.
When adaptive cruise control is
deactivated, the control indicator m
and C in the Driver Information
Centre changes from green to white
and a pop-up message is displayed.
The stored speed is maintained. The
system is deactivated but not
switched off.9 Warning
When adaptive cruise control is
deactivated, the driver must take
over full brake and engine control.
Switching off
Press C to switch off adaptive cruise
control. The control indicator m or C
extinguishes. The stored speed is
deleted.
Switching off the ignition also
switches off adaptive cruise control
and deletes the stored speed.
Driver's attention ● Use adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and need time to detect it
again.
● Do not use the system on slippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that you
could lose control of the vehicle.
● Do not use adaptive cruise control during rain, snow or
heavy dirt, as the radar sensor
can be covered by a water film,
dust, ice or snow. This reduces or suppresses completely the
visibility. In case of sensor
blockage, clean the sensor
cover.
System limits ● The system's automatic brake force does not permit hard
braking and the braking level
may not be sufficient to avoid a
collision.
● After a sudden lane change, the system needs a certain time to
detect the next preceding
vehicle. So if a new vehicle is
detected, the system may
accelerate instead of braking.
● Adaptive cruise control does ignore the oncoming traffic.

Clearing of traffic signs
There are different scenarios that
lead to clearing the currently
displayed traffic signs. After clearing,
the “Default Sign” is displayed in the
Driver Information Centre.
Reasons for signs being cleared: ● A predefined distance was driven
or time has elapsed (differs for
each sign type)
● Vehicle drives through a turn
● The speed becomes slower than 52 km/h (city entry detection)
222Driving and operatingFuel consumption data and CO2
emission data are determined
according to regulation R (EC) No.
715/2007 (in the version respectively
applicable), taking into consideration
the vehicle weight in running order, as specified by the regulation.
The figures are provided only for the
purpose of comparison between
different vehicle variants and must not be taken as a guarantee for the
actual fuel consumption of a
particular vehicle. Additional
equipment may result in slightly
higher results than the stated
consumption and CO 2 figures.
Furthermore, fuel consumption is
dependent on personal driving style
as well as road and traffic conditions.Trailer hitch
General information
The factory-fitted towing equipment is
folded up under the rear bumper
fascia.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment. Only use
towing equipment that has been
approved for your vehicle.
To avoid vehicle damage, the power
tailgate cannot be operated with the
radio remote control when a trailer is
electrically connected.
The bulb outage detection function for trailer brake light cannot detect a
partial bulb outage, e.g. in case of four
times five watt bulbs, the function only detects lamp outage when only a
single five Watt lamp remains or none
remain.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ball bar for towing.Driving characteristics and
towing tips
Before attaching a trailer, lubricate the coupling ball. However, do not do
so if a stabiliser, which acts on the
coupling ball, is being used to reduce snaking movements.
For trailers with low driving stability
and trailers with a permitted gross
vehicle weight of more than 1400 kg (Front-wheel drive)/1600 kg (All-
wheel drive) the use of a stabiliser is
strongly recommended when driving
above 80 km/h.
If the trailer starts snaking, drive more
slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 295.
262Vehicle careNote
The driving characteristics of the repaired tyre is severely affected,
therefore have this tyre replaced.
If unusual noise is heard or the
compressor becomes hot, turn
compressor off for at least 30
minutes.
The built-in safety valve opens at a
pressure of 7 bar.
Note the expiry date of the kit. After
this date its sealing capability is no
longer guaranteed. Pay attention to
storage information on sealant
bottle.
Replace the used sealant bottle. Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be used from approx. -30 °C.
The adapters supplied can be used
to pump up other items e.g.
footballs, air mattresses, inflatable
dinghies etc. They are located on the underside of the compressor. To
remove, screw on compressor air hose and withdraw adapter.Wheel changing
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel
3 259.
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-skid surface. The front
wheels must be in the straight- ahead position.
● Apply the parking brake and engage first gear, reverse gear or
P .
● Remove the spare wheel 3 264.
● Never change more than one wheel at once.
● Use the jack only to change wheels in case of puncture, not
for seasonal winter or summer
tyre change.
● The jack is maintenance-free.
● If the ground on which the vehicle
is standing is soft, a solid board
(max. 1 cm thick) should be
placed under the jack.
● Take heavy objects out of the vehicle before jacking up.● No people or animals may be in the vehicle when it is jacked-up.
● Never crawl under a jacked-up vehicle.
● Do not start the vehicle when it is
raised on the jack.
● Clean wheel nuts and thread with
a clean cloth before mounting the
wheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
1. Disengage wheel nut caps with a screwdriver and remove.
Steel wheels with cover: Pull off
the wheel cover.
Alloy wheels: Disengage wheel
nut caps with a screwdriver and

Spare wheel Some vehicles are equipped with a
tyre repair kit instead of a spare
wheel.
If mounting a spare wheel, which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
Vehicle care265even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.
The spare wheel has a steel rim.Caution
The use of a spare wheel that is smaller than the other wheels or in
combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
The spare wheel is located in the load
compartment beneath the floor
covering.
To remove:
1. Open the floor cover.
2. The spare wheel is secured with a
wing nut. Turn wing nut
anticlockwise and remove the
spare wheel.
Under the spare wheel there is the box with vehicle tools.
3. When, after a wheel change, no wheel is placed in the spare wheel
well, secure the tool box by
turning right back the wing nut and close the floor cover.
Stowing the replaced full size
wheel in the spare wheel well
The spare wheel well is not designed for all permitted tyre sizes. If a wheel
wider than the spare must be stowed
in the spare wheel well, the thread
bolt for mounting the wheel must be
replaced by an extension bolt, located
in the tool box 3 253. To replace the
bolt:
● Remove tool box from the spare wheel well.
● Install the hexagon key of thewheel wrench ensuring that it
locates securely on the bolt.
● Turn the wheel wrench anticlockwise to loosen the bolt.
Remove the bolt.
● Take the extension bolt from the tool box 3 253 and screw it in
hand-tight using the hexagon key of the wheel wrench.
266Vehicle care
● Store the tool box and thedamaged wheel facing upwards
in the spare wheel well and
secure it by turning the wing nut
clockwise on the bolt.
The floor cover can be placed on the
projecting wheel.
To fit the spare wheel in the well after
renewing the defective wheel use the
short thread bolt again. Exchange the bolt in the same way.
9 Warning
Storing a jack, a wheel or other
equipment in the load
compartment could cause injury if they are not fixed properly. During a sudden stop or a collision, looseequipment could strike someone.
Store wheel, jack and tools always
in the original storage location and secure them by fixing.
Temporary spare wheel
Caution
The use of a spare wheel that issmaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
Only mount one temporary spare
wheel. Do not drive faster than
80 km/h. Take curves slowly. Do not use for a long period of time.
