162Driving and operatingOnce the system is activated,
adaptive cruise control decelerates or
brakes if it detects a vehicle ahead,
which is slower or closer than the
desired following distance.9 Warning
Accelerating by the driver
deactivates automatic braking by
the system. This is indicated as a
pop-up warning in the Driver
Information Centre.
Increase speed
With adaptive cruise control active,
hold thumb wheel turned to RES/+:
speed increases continuously in large
increments, or activate repeatedly
RES/+ : speed increases in small
increments.
If the vehicle is driven with adaptive cruise control active much faster than
the desired speed, e.g. after
depressing the accelerator pedal,
then the current speed can be stored
and maintained by turning the thumb
wheel to SET/-.
Reduce speed
With adaptive cruise control active,
hold thumb wheel turned to SET/-:
speed decreases continuously in
large increments, or activate
repeatedly SET/-: speed decreases in
small increments.
If the vehicle is driven with adaptive
cruise control active much slower
than the desired speed, e.g. because of a slower vehicle ahead, then the
current speed can be stored and
maintained by turning the thumb
wheel to SET/-.
Resume stored speed If the system is switched on but
inactive, then turn thumb wheel to
RES/+ at a speed above 31 mph to
resume the stored speed.
Setting the following distance
When adaptive cruise control detects a slower moving vehicle in the drivingpath, it will adjust the vehicle speed to
maintain 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 top line of the Driver
Information Centre.

164Driving and operating● There is no traffic and nothingdetected on the road sides forseveral minutes. In this case,
there are no radar echoes and
the sensor may report that it is
blocked.
● The collision imminent braking system 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.
When adaptive cruise control is
deactivated automatically, the control indicator m illuminates white and a
warning symbol is displayed as a pop-
up in the Driver Information Centre.
The stored speed is maintained.
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
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.
● 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.

Vehicle care237Make 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 3 240.
● 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. Pull off
the wheel cover. Vehicle tools
3 225.
Alloy wheels: Disengage wheel
nut caps with a screwdriver and
remove. To protect the wheel,
place a soft cloth between the
screwdriver and the alloy wheel.Alloy wheels with centre wheel
bolt cap: Disengage centre cap by
inserting and pulling the extractor
in the recess of the brand
emblem. Vehicle tools 3 225.
2. Two types of jacks and wheel nut wrenches are possible dependingon the version. Vehicle tools
3 225.
Variant 1a with rigid wheel
wrench:

Vehicle care239
Set the jack to the necessary
height. Position it directly below
the jacking point in a manner that
prevents it from slipping.
Attach jack handle and with the
jack correctly aligned rotate
handle until wheel is clear of the ground.
5. Unscrew the wheel nuts.
6. Change the wheel. Spare wheel 3 240.
7. Screw on the wheel nuts.
8. Lower the vehicle and remove jack.
9. Install the wheel wrench ensuring that it is located securely and
tighten each nut in a crosswise
sequence. Tightening torque is
140 Nm.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
Install centre cap on alloy wheels.
11. Install vehicle jacking point cover on versions with sill panelling.
12. Stow the replaced wheel 3 240,
the vehicle tools 3 225 and the
adapter for the locking wheel nuts 3 58.
13. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.Have the defective tyre renewed or repaired as soon as possible.
Jacking position for lifting platform
Rear arm position of the lifting
platform centrically under the recess
of the sill.

240Vehicle care
Front arm position of the lifting
platform at the underbody.
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,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.
The spare wheel has always 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. It is secured with a wing nut.
To remove: 1. Open the floor cover.
2. Only 3-door hatchback: remove rear storage by pressing both
buttons. Fold down cover and
extract storage upwards.
3. The spare wheel is secured with a
wing nut. Loosen nut, remove
conus (only 3-door hatchback) to
take out the spare wheel.
Under the spare wheel there is the box with vehicle tools.
4. When, after a wheel change, no wheel is placed in the spare wheel
well, secure the tool box by
tightening the wing nut and close
the floor cover.
