Driving and operating183Change speed limit
With speed limiter active, hold or
briefly turn thumb wheel to RES/+ to
increase or SET/- to decrease the
desired maximum speed.
Exceeding the speed limit
When exceeding the limited speed
without driver input, the speed will
flash in the Driver Information Centre
and a chime sounds during this
period.
In the event of an emergency, it is
possible to exceed the speed limit by
depressing the accelerator pedal
firmly nearly to the final point. In this
case no chime appears.
Release the accelerator pedal and the speed limiter function is
reactivated once a speed lower than
the limit speed is obtained.
Deactivation Press y: speed limiter is deactivated
and the vehicle can be driven without
speed limit.The limited speed will be stored and
is indicated in brackets in the Driver
Information Centre. Additionally, a
corresponding message appears.
Resume limit speed
Turn thumb wheel to RES/+. The
stored speed limit will be obtained.
Switching off
Press L, the speed limit indication in
the Driver Information Centre
extinguishes. The stored speed is
deleted.
By pressing m to activate cruise
control or adaptive cruise control,
speed limiter is also deactivated and
the stored speed is deleted.
By switching off the ignition, speed
limiter is also deactivated, but the
speed limit will be stored for next
speed limiter activation.Adaptive cruise control
Adaptive cruise control (ACC) is an
enhancement to traditional cruise
control with the additional feature of
maintaining a certain distance behind the vehicle ahead.
Adaptive cruise control automatically decelerates the vehicle when
approaching a slower moving vehicle. It then adjusts the vehicle speed to
follow the vehicle ahead at the
selected following distance. The
vehicle speed increases or decreases
to follow the vehicle in front, but will
not exceed the set speed. It may
apply limited braking with activated
brake lights.
The adaptive cruise control can store and maintain speeds over approx.
15 mph. If following a vehicle ahead
driving slower than 15 mph, the
slower speed will be set. On vehicles
with automatic transmission, the
system brakes to a stop.
186Driving and operatingWhen the vehicle ahead stops for
more than two minutes, the electrical
parking brake will apply automatically and the full speed range adaptive
cruise control will be deactivated. In
this event, drive the vehicle normally
by operating the accelerator pedal.
Turn thumb wheel to RES/+ at a
speed above 6 mph to resume full
speed range adaptive cruise control.9 Warning
When full speed range adaptive
cruise control is deactivated or
cancelled, the vehicle will no
longer be held at a stop and can
start to move. Always be prepared to manually apply the brake to hold the vehicle stationary.
Do not leave the vehicle while it is being held at a stop by the full
speed range adaptive cruise
control. Always move selector
lever to park position P and switch
off the ignition before leaving the
vehicle.
Setting the following distance
When adaptive cruise control detects
a slower moving vehicle in the driving path, it will adjust the vehicle speed tomaintain the following distance
selected by the driver.
The following distance can be set to
near, medium or far.
Press E, the current setting is shown
in the Driver Information Centre.
Press E again to change the
following distance. The setting is also displayed in the Driver Information
Centre.
The selected following distance is
indicated by filled distance bars in the
adaptive cruise control page.
Note that the following distance
setting is shared with the sensitivity
setting of forward collision alert
3 190.
Example: If setting 3 (far) is selected,
then the driver is warned sooner
before a possible collision, also if
adaptive cruise control is inactive or
switched off.
188Driving and operating9Warning
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.● Adaptive cruise control does notbrake for pedestrians, animals,very slow speed driving or
stopped vehicles.
● Don't use adaptive cruise control when towing a trailer.
Bends
The adaptive cruise control calculates
a predicted path based on the
centrifugal force. This predicted path
considers the current bend
characteristic, but cannot consider a
future bend change. The system may lose the current vehicle ahead or
consider a vehicle which is not in the
actual lane. This can happen when
entering or exiting a bend or if the
bend gets stronger or weaker. If it no
longer detects any vehicle ahead,
then control indicator A will
extinguish.
260Vehicle careNotice
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
3 257.
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 3 262.
● 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

different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
Vehicle care263even 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.

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 3 251. 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.

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
