208Vehicle careIn this case reduce speed, avoid
sharp cornering and strong braking.
Stop at next safe opportunity and
check tyre pressure.
Control indicator w 3 94.
After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.Caution
Deflation detection system warns
just about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
In case of a system malfunction a
message is displayed in the Driver
Information Centre. Set correct tyre
pressure and reinitialise system. If the
failure continues to be displayed,
contact a workshop. The system is
inoperable when ABS or ESC has a
malfunction or a temporary spare
wheel is used. Once the road tyre has
been refitted, check the tyre pressure with cold tyres and initialise the
system.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised to learn new circumference reference values:
1. Always ensure that all four tyres have correct tyre pressure3 239.
2. Apply manual parking brake.
3. Press w to reset deflation
detection system.
4. Reset is confirmed by pop-up indication.
After initialisation system
automatically calibrates to new tyre
pressures during driving. After longer
drive the system will adopt and
monitor new pressures.
Always check tyre pressure with cold
tyres.
System has to be reinitialised when: ● Tyre pressure has been changed
● Load condition has been changed
● Wheels have been swapped or exchanged
The system will not warn instantaneously on a tyre blow out or
a rapid deflation. This is due to
required calculation time.
Tread depthCheck tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).

Vehicle care213Repeat the checking procedure
once more after driving further
10 km (but no more than ten
minutes) to check that there is no
more loss of pressure
If the tyre pressure has fallen
below 1.5 bar, the vehicle must
not be used. Seek the assistance
of a workshop.
17. Stow away tyre repair kit in load compartment.
Note
The driving characteristics of the
repaired tyre are 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 seven 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.
Wheel changing Some vehicles are equipped with a
tyre repair kit instead of a spare wheel
3 210.
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 3 216.
● 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.
● Before screwing in the wheel bolts, clean them.9Warning
Do not grease wheel bolts.
9Warning
Ensure to use always the correct
wheel bolts if changing the
wheels. When installing the spare
wheel, the bolts for alloy wheels can also be used.

Vehicle care215the jacking point in a manner thatprevents it from slipping.
Ensure that the edge of the body
fits into the notch of the jack.
Attach wheel wrench and with the
jack correctly aligned rotate wheel wrench until wheel is clear of the
ground.
5. Unscrew the wheel bolts. 6. Change the wheel. Spare wheel 3 216.
7. Screw on the wheel bolts.
8. Lower vehicle.
9. Install the wheel wrench ensuring that it is located securely and
tighten each bolt in a crosswise
sequence. Tightening torque is
100 Nm for all wheels.
If the vehicle is equipped with
alloy wheels, note that the wheel
bolts can also be used for the steel spare wheel. In this case, the
spare wheel is secured by the
conical contact of each bolt.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel bolt caps.11. Stow and secure the replaced wheel 3 216, the vehicle tools
3 205 and the adapter for the
locking wheel bolts 3 65.
12. Check the tyre pressure of the installed tyre and the wheel bolt
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 at the underbody.

216Vehicle care
Front arm position of the lifting
platform at the underbody.
Spare wheel Mounting the temporary spare
wheel
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.
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.
The temporary spare wheel has a
steel rim.
The temporary spare wheel is located in the load compartment beneath the
floor covering.
To remove: 1. Open the floor cover.
2. The temporary spare wheel is secured with a wing nut. Turn
wing nut anticlockwise and
remove the wheel.
There is a box with tools in the
right wall of the load
compartment. Vehicle tools 3 205
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.
4. After a wheel change back to a full
size wheel, place the spare wheel outside up in the well and secure
with the wing nut.
If your vehicle gets a flat tyre on the
rear while towing another vehicle,
mount the temporary spare wheel in
the front and the full tyre in the rear.
Tyre chains 3 210.
Stowing a damaged full size
wheel in the load compartment
The spare wheel well is not designed
for other tyre sizes than the temporary spare wheel. A damaged full size
wheel must be stowed in the load
