214Vehicle careWheel changingSome vehicles are equipped with a
tyre repair kit instead of a spare wheel
3 211.
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 3 144.
● Remove the spare wheel 3 216.
● 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 thewheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
1. Remove the wheel cover using the hook supplied.
Vehicle tools 3 204.
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.
2. Install the wheel wrench (depending on vehicle, attach
wheel wrench to adapters)
ensuring that it is located securely and loosen each wheel bolt/nut byhalf a turn.

3. Vehicles with Front-wheel drive:If equipped, attached heightener
to lifting pad when changing a
front wheel.
Raise vehicle by placing lifting
pad spigot of the jack (vehicle
tools 3 204) under the jacking
hole located nearest the wheel
concerned.
Ensure the jack is positioned
correctly. The jack base must be
on the ground directly below the
jacking hole in a manner that
prevents it from slipping.
Attach wheel wrench onto the jack
and raise the vehicle (max. 3 cm)
by turning the wrench until the
wheel is clear of the ground.
Vehicles with Rear-wheel drive:
Pay attention to the operating
instructions supplied with the
hydraulic jack (vehicle tools
3 204) and assemble the parts
required as specified.
Position the adapter at the jacking
hole located nearest the wheel
concerned.
Ensure the jack is positioned
correctly. The jack head must be
level with the jacking hole. Pump
the jack by pressing the wheel
wrench / adapters, to position the base plate correctly.
Raise the vehicle (max. 3 cm) bypressing 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.
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.
216Vehicle careNote
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 3 216
and the vehicle tools 3 204.
11. Have the new wheel balanced on the vehicle. Check the tyre
pressure of the installed tyre
3 252 and also the wheel bolt /
nut torque as soon as possible.
Have the defective tyre renewed or
repaired.
Spare wheel Some vehicles are equipped with atyre repair kit instead of a spare wheel
3 211.
The spare wheel can be classified as
a temporary spare wheel depending
on the size compared to the other
mounted 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.
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.
