190Driving and operating9Warning
Towing a trailer is permitted only
when a coupling ball bar is fitted correctly. If the coupling ball bardoes not engage correctly, seekthe assistance of a workshop.
Dismounting the coupling ball bar
Insert the key in the lock and unlock
the coupling ball bar.
Push the rotary knob onto the
coupling ball bar and rotate right while pressed down until it engages. Pull
out the ball bar downwards.
Insert sealing plug in opening for
coupling ball bar. Fold away socket.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While system is working keep
steering wheel as still as possible.
Trailer stability assist is a function of
the Electronic Stability Control 3 154.

Tools
Vehicles without spare wheel
The tools are located together with
the towing eye in the load
compartment below the floor cover.
Page 215 of 271

Vehicle care213
The tools and the towing eye are
located on the right side of the load compartment behind a cover.
On OPC or LPG version or versions with rear carrier system, the tools are located together with the towing eye
on the right side of the load
compartment, behind a cover.
Vehicles with spare wheel
The jack, wheel bolt wrench and
some tools are located on the right
side of the load compartment, behind a cover 3 70.
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.
We recommend not swapping the
front wheels with the rear wheels and vice versa, as this can affect vehicle
stability. Always use less worn tyres
on the rear axle.
Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and should
therefore be fitted on all wheels.
All tyre sizes are permitted as winter
tyres 3 255.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
Page 223 of 271

Vehicle care221Tyre 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 permitted on tyres of
size 175/70 R14, 185/70 R14,
185/65 R15, 205/45 R17.
Tyre chains are permitted on tyres of
size 195/55 R16 with rims of size
16 x 6 and 16 x 6.5, the latter only in combination with limited steering
angle. Seek the assistance of a
workshop.
Tyre chains are not permitted on tyres of size 215/45 R17 and 215/40 R18.
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 the tyre's side wall near the rim
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 stowed in the load
compartment.
Depending on the equipment, the tyre repair kit is in a compartment in the
right sidewall or in a compartment
under the floor cover.
Vehicles with tyre repair kit under
the floor cover
1. Take the tyre repair kit from the compartment.
2. Remove the compressor.

3. Remove the electrical connectioncable 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.
6. Unscrew valve cap from defective
tyre.
7. Screw the filler hose to the tyre valve.
8. The switch on the compressor must be set to J.
9. Connect the compressor plug to
the power outlet or cigarette
lighter socket.
To avoid discharging the battery,
we recommend running the
engine.
10. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to six bar
whilst the 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 inflated.

Vehicle care22313. The prescribed tyre pressureshould be obtained within ten
minutes.
Tyre pressure 3 255.
When the correct pressure is
obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within ten minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
ten 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 over the pressure indicator.
Do not run the compressor for
longer than ten minutes.
14. Detach the tyre repair kit. Push catch on bracket to remove
sealant bottle from bracket. Screw the tyre inflation hose to the freeconnection 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.
10 km (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.
