Vehicle care197The pressure increases by nearly
10 kPa for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
Tyre deflation detectionsystem
The tyre deflation detection system
continually checks the rotation speed
of all four wheels and warns on low
tyre pressure condition once vehicle
is driving. This is achieved by
comparing tyre rolling circumference
with reference values and further
signals.
If a tyre loses pressure the control
indicator w illuminates and a warning
message is displayed in the Driver
Information Centre.
In this case reduce speed, avoid
sharp cornering and strong braking.
Stop at next safe opportunity and
check tyre pressure.
Control indicator w 3 85.
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.
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.
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 230.
2. Apply parking brake. 3. Press w to reset deflation
detection system.
4. Reset is confirmed by pop-up indication.
198Vehicle careAfter 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 depth
Check 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).
For safety reasons, it is
recommended that the tread depth of
the tyres on one axle should not vary
by more than 2 mm.
The legally permissible minimum tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. If directional tyres are mounted, ensure that thedirection of rotation of the wheels
remains the same.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the tyre
deflation detection system and make
other vehicle modifications.
Tyre deflation detection system
3 197.
Have the label with tyre pressures
replaced.9 Warning
The use of unsuitable tyres or
wheels may lead to accidents and will invalidate the vehicle
operating permit.
Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Vehicle care199Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Vehicles with steel wheels: When
using locking wheel nuts, do not
attach wheel covers.
Tyre chains
Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add no more than 10 mm to the tyre tread
and the inboard sides (including chain lock).9 Warning
Damage may lead to tyre blowout.
Tyre chains are only permitted on
tyres of size 195/65 R15 91 and
195/60 R16 89
Temporary spare wheel
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit
Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is at tyre's sidewall cannot be repaired with the tyre repair kit.
9 Warning
Do not drive faster than 80 km/h.
Do not use for a lengthy period.
Steering and handling may be
affected.
If you have a flat tyre:
Apply the parking brake and engage
first gear, reverse gear or P.
The tyre repair kit is in the load
compartment below the floor cover.
1. Remove the sealant bottle and the
compressor.
Vehicle care201
10. Set the rocker switch on thecompressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to 6 bar whilstthe sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is being
inflated.
13. The prescribed tyre pressure should be obtained within
10 minutes.
Tyre pressure 3 230.
When the correct pressure is
obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
10 minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button on the air hose.
Do not run the compressor longer
than 10 minutes.
14. Detach the tyre repair kit. Remove
sealant bottle from bracket. Screw
the filler hose to the free connection of the sealant bottle.
This prevents sealant from
escaping. Stow tyre repair kit in
load compartment.
15. Remove any excess sealant using a cloth.
16. Continue driving immediately sothat sealant is evenly distributed
in the tyre. After driving approx.
5 km (but no more than 10 min),
stop and check tyre pressure.
Screw compressor air hose
directly onto tyre valve when
doing this. Fill tyre as described
202Vehicle carebefore. Drain excess tyrepressure with the button on the air
hose.
If tyre pressure hasn't decreased under 1.5 bar, set it to the correct
value. Otherwise the vehicle must
not be used. Seek assistance of a workshop.
Repeat the checking procedure
once more after driving further
10 km (but no more than
10 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 700 kPa (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.
Wheel changing
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.
● If necessary, place a chock under
the wheel diagonally opposite the wheel to be changed.
● Apply the parking brake and engage first gear, reverse gear or
P .● 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.
Tightening torques
Caution
If the vehicle is equipped with alloy
wheels, tighten the wheel bolts
manually at least for the first five
turns.
206Vehicle careAttach wheel wrench and with the
jack correctly aligned rotate wheel wrench until wheel is clear of the
ground.
5. Unscrew the wheel nuts. 6. Change the wheel.
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 bolt in a crosswise
sequence. Tightening torque is
100 Nm.
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. In this
case, the washers do not come
into contact with the spare wheel.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
11. Stow and secure the replaced wheel and the tools.
12. Check the tyre pressure of the installed tyre and the tightening
torque as soon as possible.
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
compartment and secured with a
strap.
Vehicle tools 3 194.To secure the wheel:
1. Position the wheel outside up close to one sidewall of the load
compartment.
2. Place the loop end of the strap through the front lashing eye on
the appropriate side.
3. Place the hook end of the strap through the loop and pull it until
the strap is fastened securely to
the lashing eye.
