Vehicle care299not be driven. Seek the
assistance of a workshop.
21. Stow tyre repair kit under the front
seat.
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 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-slippery surface. The
front wheels must be in the
straight-ahead position.
● Apply the parking brake and engage first gear or reverse gear(manual transmission) or N
(manual transmission
automated).
● Switch off the air suspension system 3 231.
● Remove the spare wheel 3 301.
● Never change more than one wheel at a time.
● 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.● 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 engine when the vehicle is raised on the jack.
● Clean wheel bolts / nuts and their
threads before mounting the
wheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
1. Remove the wheel cover using the hook supplied.
Vehicle tools 3 290.
Depending on vehicle, first
remove the bolt / nut covers by
hand then remove the wheel
cover, or press wheel cover at the points indicated by the arrows and
turn to release.
Rear-wheel drive, with twin rear
wheels: Remove the tyre valve
extender from the inner rear
wheel.
Vehicle care301Raise the vehicle by pressing the
wheel wrench until the wheel is
clear of the ground.
4. Unscrew wheel bolts / nuts completely and wipe clean with a
cloth.
Put wheel bolts / nuts somewhere
where the threads will not be
soiled.
5. Change the wheel.
6. Screw in the wheel bolts / nuts. Separately supplied bolts must beused for the temporary spare
wheel. These are allowed only for the temporary spare wheel. Refer
to an label on the temporary spare
wheel.
7. Lower vehicle.
8. Install the wheel wrench (depending on vehicle, attach
wheel wrench to adapters)
ensuring that it is securely located and tighten each wheel bolt / nut
in a crosswise sequence.
Tightening torque is: 172 Nm
(Front-wheel drive), 235 Nm(Rear-wheel drive with twin rear
wheels), 264 Nm (Rear-wheel
drive with single rear wheels).
9. Refit wheel cover. Rear-wheel drive, with twin rear
wheels: Install the tyre valve
extender to the inner rear wheel
before refitting the wheel cover.
Note
If applicable, fit anti-theft bolts
nearest the tyre valve (otherwise it
may not be possible to refit the wheel
cover).
10. Stow the replaced wheel 3 301
and the vehicle tools 3 290.
11. Have the new wheel balanced on the vehicle. Check the tyre
pressure of the installed tyre
3 317 and also the wheel bolt /
nut torque as soon as possible.
Have the defective tyre renewed or
repaired.
Spare wheel
The spare wheel can be classified as
a temporary spare wheel depending
on the size compared to the othermounted wheels and country
regulations. In this case a permissible maximum speed applies, even
though no label at the spare wheel
indicates this.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.
The spare wheel is held under the
vehicle frame using a winch and
secured by tightening a cable using
the wheel wrench and adapters
(depending on vehicle).
It may be necessary to jack the
vehicle up to gain access to the spare
wheel on a fully loaded vehicle with a flat rear tyre.
302Vehicle care
To release the spare wheel, loosen
cable by connecting the wheel
wrench and adapters (depending on
vehicle) to the slot position illustrated
and lower the wheel fully by turning
wrench clockwise.
Caution
Only use the wheel wrench and
adapters (depending on vehicle)
to lower the spare wheel.
The use of pneumatic tools is
prohibited. This may result in
damage to the winch cable and
equipment.
Place wheel upright, unclip retainer
from wheel rim and release the wheel
from the cable and connected
retainer by routing these components through the centre of the wheel.
Twin rear wheel vehicles have an
additional mounting plate attached to
the spare wheel. Before using the
wheel, undo the nut and remove the
mounting plate.When reinstalling a spare wheel, first
attach the mounting plate (twin rear
wheel vehicles) and secure with the
nut.
Place wheel upright, then route the
cable and connected retainer from
the front of the wheel (side with tyre
valve) and through the centre of the
wheel. Attach the retainer and clip it
into place, ensuring it is correctly
positioned and that the front of the
wheel (side with tyre valve) will be
facing upwards when reinstalled.
Vehicle care303
Place wheel below the vehicle frame,
directly beneath the winch
mechanism.
Then tighten cable using the wheel
wrench and adapters by connecting
to the slot position illustrated above
and turning wrench anticlockwise
until the wheel is secured in the fully
raised position.
Note
Do not place a wheel with aluminium rim under the vehicle frame.9 Warning
Ensure the front of the wheel (side
with tyre valve) is facing upwards
when the spare wheel is
reinstalled below the vehicle
frame.
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
80 km/h. Take curves slowly. Do not use for a long period of time.
Separately supplied bolts must be
used for the temporary spare wheel.
These are allowed only for the
temporary spare wheel. Refer to an
label on the temporary spare wheel.
Tyre chains 3 295.
Summer and winter tyres
If you use winter tyres, the spare
wheel may still be fitted with a
summer tyre.
If you use the spare wheel when it is
fitted with a summer tyre the vehicle's driveability may be affected,
especially on slippery road surfaces.
Directional tyres Fit directional tyres such that they rollin the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
304Vehicle careThe following applies to tyres fitted
opposing the rolling direction:
● Driveability may be affected. Have the defective tyre renewed
or repaired as soon as possible
and fit it instead of the spare
wheel.
● Do not drive faster than 80 km/h.
● Drive particularly carefully on wet
and snow-covered road
surfaces.Jump starting
The jump start terminal is located in
the engine compartment.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.
Do not start with a quick charger.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
Caution
The air suspension system must
be switched off prior to jump
starting.
Air suspension 3 231.
● Never expose the vehicle battery
to naked flames or sparks.
● A discharged vehicle battery can already freeze at a temperature
of 0 °C. Defrost the frozen vehicle
battery before connecting jump leads.
● Wear eye protection and protective clothing when
handling a vehicle battery.
● Use a booster battery with the same voltage (12 V). Its capacity(Ah) must not be much less than
that of the discharged vehicle
battery.
● Use jump leads with insulated terminals and a cross section of
at least 25 mm 2
.
● Do not disconnect the discharged
battery from the vehicle.
