Vehicle care217Vehicle tools
Tools
Vehicle with spare wheel
The jack, the towing eye, a strap for
securing a damaged wheel and the tools are located in the tool box below the spare wheel in the load
compartment. Spare wheel 3 230.
Vehicles with tyre repair kit
Some tools and the towing eye are
located together with the tyre repair
kit in a tool box in the right wall of the
load compartment.
Open the cover of the storage
compartment.
Wheels and tyres
Tyre condition, wheel condition Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and shouldtherefore be fitted on all wheels.
All tyre sizes are permitted as winter
tyres 3 253.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
Page 227 of 267
Vehicle care2259Warning
Do not drive faster than 50 mph.
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 on the right side
in the load compartment behind a
cover.
1. Remove the sealant bottle.
2. Insert the thumb into the opening and pull out the compressor.
3. Remove the electrical connection cable and air hose from the
stowage compartments on the
underside of the compressor.
4. Screw the compressor air hose to
the connection on the sealant
bottle.
5. Fit the sealant bottle into the retainer on the compressor.
Set the compressor near the tyre
in such a way that the sealant
bottle is upright.
Page 229 of 267

Vehicle care22714. Detach the tyre repair kit. Pushcatch on bracket to remove
sealant bottle from bracket. Screw the tyre inflation 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. Take the label indicating maximum permitted speed from
the sealant bottle and affix in the
driver's field of view.
17. Continue driving immediately so that sealant is evenly distributedin the tyre. After driving approx.
6 miles (but no more than ten
minutes), stop and check tyre
pressure. Screw compressor air
hose directly onto tyre valve and
compressor when doing this.
If tyre pressure is more than 1.3 bar , set it to the correct value.
Repeat the procedure until there
is no more loss of pressure.
If the tyre pressure has fallen
below 1.3 bar, the vehicle must
not be used. Seek the assistance
of a workshop.
18. Stow away tyre repair kit in load compartment.
Notice
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 102 psi.
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 3 224.

4. Set the jack to the necessaryheight. Position it directly below
the jacking point in a manner that
prevents 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 nuts. 6. Change the wheel. Spare wheel 3 230.
7. Screw on the wheel nuts.
8. Lower the vehicle and remove jack.
9. Install the wheel wrench ensuringthat it locates 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.
11. Stow the replaced wheel 3 230
and the vehicle tools 3 217.
12. 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.

Vehicle care231Stowing a damaged full size
wheel in the load compartment
The spare wheel well is not designed for other tyre sizes than the spare
wheel. A damaged full size wheel
must be stowed in the load
compartment and secured with a
strap. Vehicle tools 3 217. 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.
4. Insert the strap through the spokes of the wheel as shown in
the illustration.
5. Mount the hook to the rear lashing
eye.
6. Tighten the strap and secure it using the buckle.
9 Danger
Always drive with folded up and
engaged rear seat backrests when stowing a damaged full size wheel
in the load compartment.
Temporary spare wheel
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.
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.
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.
