MERCEDES-BENZ GLS SUV 2022 Owners Manual


Avoid obstacles or drive especially care-
full
y. 
Reduce your speed when driving over
k

erbs, speed bumps, manhole covers
and potholes. 
Avoid particularly high kerbs. *
NOTE P
ossible wheel and tyre damage
when parking on kerbs or in potholes Parking on kerbs or in potholes can damage
t
he wheels and tyres. 
Only park on level surfaces if possible. 
Avoid kerbs and potholes when parking. *
NOTE Damag
e to electronic component
parts due to the use of tyre-Ntting tools Vehicles with tyre pressure monitoring sys-
t

em: there are electronic component parts in
the wheel.
If tyre-Ntting tools are positioned in the area of
the valve, the electronic components could be
damaged. 
Tyre-Ntting t
ools should not be applied in
the area of the valve. 
Always have tyres changed at a q
ualiNed
specialist workshop. *
NOTE Damag
e to summer tyres at low
ambient temperatures At low ambient temperatures, tears could form
when dr

iving with summer tyres, causing per-
manent damage to the tyre. 
At temperatures below 7 °C use M
M+S

tyres. Accessory parts which are not approved for your
v
ehicle by Mercedes-Benz, or which are not used
correctly, can impair the operating safety.
Before purchasing and using non-approved acces-
sories, visit a qualiNed specialist workshop and
enquire about:
= Suitability
= Legal stipulations
= Factory recommendations &
WARNING Risk of accident wit
h high per-
formance tyres
The special tyre tread in combination with the
op
timised tyre compound means that the risk
of skidding and hydroplaning on wet roads is
increased.
In addition, the tyre grip is greatly reduced at
a low outside temperature and tyre running
temperature. 
Switch on the ESP n
and adap
t your driv-
ing style accordingly. 
Use M M+S
tyres at outside tempera-
tures of less than 10 °C. 
Only use the tyres for their intended pur-
pose. Observe the following when selecting,
Ntting and
r
eplacing tyres:
= Country-speciNc requirements for tyre
approval that deNne a speciNc tyre type for
your vehicle. 408
Wheels and tyres

=
F urthermore, the use of certain tyre types in
certain regions and areas of operation can be
highly beneNcial.
= Only use tyres and wheels of the same type
(summer tyres, winter tyres, MOExtended
tyres) and the same make.
= Only Nt wheels of the same size on one axle
(les and right).
It is only permissible to Nt a diMerent wheel
size in the event of a Oat tyre in order to drive
to the specialist workshop.
= Do not make any modiNcations to the brake
system, the wheels or the tyres.
The use of shims or brake dust shields is not
permitted and may invalidate the vehicle's
general operating permit.
= Vehicles with a tyre pressure monitoring sys-
tem: all Ntted wheels must be equipped with
functioning sensors for the tyre pressure mon-
itoring system.
= At temperatures below 7 °C use winter tyres
or all-season tyres marked M M+S for all
wheels. Winter tyres provide the best possible grip in
wintr
y road conditions.
= For M+S tyres, only use tyres with the same
tread.
= Observe the maximum permissible speed for
the M+S tyres Ntted.
If the tyre's maximum speed is below that of
the vehicle, this must be indicated by an
appropriate label in the driver's Neld of vision.
= Run in new tyres at moderate speeds for the
Nrst 100 km.
= Replace the tyres aser six years at the latest,
regardless of wear.
= When replacing with tyres that do not feature
run-Oat characteristics: vehicles with
MOExtended tyres are not equipped with a
TIREFIT kit at the factory. Equip the vehicle
with a TIREFIT kit aser replacing with tyres
that do not feature run-Oat characteristics,
e.g. winter tyres.
% You can permanently limit the maximum
speed f

or driving with winter tyres
(  page 243). For more information on wheels and tyres, con-
t
act a qualiNed specialist workshop.

ted subjects: = Notes on tyre pressure (  page 403)

&
WARNING Risk of injur
y through diMerent
wheel sizes
Interchanging the front and rear wheels can
se
verely impair the driving characteristics.
The disk brakes or wheel suspension compo-
nents may also be damaged. 
Only interchange the front and rear
wheels if t
he wheels and tyres have the
same dimensions. Wheels and tyres
409

Interchanging the front and rear wheels if the
wheels or tyr
es have diMerent dimensions can
render the general operating permit invalid.
Observe the instructions and safety notes on
"Changing a wheel" ( page 406)
The wear patterns on the front and rear wheels
diMer:
= front wheels wear more on the tyre shoulder
= rear wheels wear more in the centre of the
tyre
Do not drive with tyres that have too little tread
depth. This signiNcantly reduces traction on wet
roads (aquaplaning).
On vehicles with the same front and rear wheel
size, you can interchange the wheels every
5,000 to 10,000 km, depending on the wear.
Ensure the direction of rotation is maintained for
the wheels. Notes on storing wheels
When storing wheels, observe the following notes:
= Aser r

emoving wheels, store them in a cool,
dry and preferably dark place.
= Protect the tyres from contact with oil, grease
or fuel. Overview of the tyre-change tool kit
Apart from some
countr
y-speciNc variants, vehi-
cles are not equipped with a tyre-change tool kit.
For more information on which tools are required
and approved to perform a wheel change on your
vehicle, consult a qualiNed specialist workshop.
Required tyre-changing tools may include,
forexample:
= Jack
= Chock
= Wheel wrench
% The jack weighs approximately 3.4 kg.
The maximum load capacity of t
he jack can
be found on the sticker aPxed to the jack. The jack is maintenance-free. If there is a
malfunction, please cont

act a qualiNed spe-
cialist workshop.
Tyre-change tool kit 1 is locat
ed under the load
compartment Ooor.
% Depending on the model, the tyre change tool
kit ma

y be located in other positions under
the load compartment Ooor. The tyre-change tool kit includes the following:

WARNING Risk of accident fr
om losing a
wheel
Oiled or greased wheel bolts can cause the
wheel bolts t
o come loose, as too can dam-
aged wheel bolts or wheel hub threads. 
Never oil or grease the threads. 
In the event of damage to the threads,
cont

act a qualiNed specialist workshop
immediately. 
Have the damaged wheel bolts or dam-
ag

ed hub threads replaced. 
Do not continue driving. 
Observe the information on the choice of tyres
( pag

e 406).
For tyres with a speciNed dir
ection of rotation, an
arrow on the side wall of the tyre indicates the
correct direction of rotation. Observe the direc-
tion of rotation when Ntting. 
Place the wheel to be Ntt
ed on the wheel hub
and push it on. &
WARNING Risk of injur
y from tightening
wheel bolts and nuts
If you tighten the wheel bolts or wheel nuts
when t
he vehicle is raised, the jack could tip. 
Only tighten wheel bolts or wheel nuts
when t

he vehicle is on the ground. 
Observe the instructions and safety notes on
"Changing a wheel"

( page 406). 
For safety reasons, only use wheel bolts which
ha

ve been approved by Mercedes-Benz and
for the wheel in question. 
Tighten the wheel bolts evenly in a diagonal
patt
ern in the order indicated until they are
Nnger-tight. 
If the collapsible emergency spare wheel has

% Not for Mercedes-Maybach vehicles.
Observe the following notes on Ntting an emer
-
gency spare wheel:
= The maximum permissible speed with an
emergency spare wheel Ntted is 80 km/h.
= Do not Nt the emergency spare wheel with
snow chains.
= Replace the emergency spare wheel aser six
years at the latest, regardless of wear.
= Use the wheel bolts that are included with the
emergency spare wheel. =
Chec
k the tyre pressure of the emergency
spare wheel Ntted. Correct the pressure as
necessary.
% The speciNed tyr
e pressure is stated on the
label of the emergency spare wheel.
% Vehicles with a tyre pressure monitoring sys-
t
em: if an emergency spare wheel is Ntted, the
tyre pressure monitoring system cannot func-

gency spare wheel is Ntted, the system may
still display the tyre pressure of the removed
wheel. Only restart the system again when the
emergency spare wheel has been replaced
with a new wheel.
