Vehicle care207System 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 238.
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).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. Ensure that
the direction of rotation of the wheels
remains the same.
212Vehicle careReplace 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 3 209.
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 3 214.
● 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.
● Note that the spare wheel is secured by the conical contact ofeach bolt if the wheel bolts for the
alloy wheels are used. In this
case, the washers do not come
into contact with the spare wheel.
1. Disengage wheel bolt caps with a
screwdriver and remove.
Steel wheels with cover: Pull off
the wheel cover.
Alloy wheels: Disengage wheel
bolt caps with a screwdriver and
remove. To protect the wheel,
place a soft cloth between the
screwdriver and the alloy wheel.
214Vehicle careAttach 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 3 214.
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 3 214, the vehicle tools
3 204 and the adapter for the
locking wheel bolts 3 64.
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.
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
50 mph. Take curves slowly. Do not use for a long period of time.
Vehicle care215Caution
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 3 204
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 3 208.
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 loadcompartment and secured with a
strap. Vehicle tools 3 204. 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.
