2017 MERCEDES-BENZ GLA SUV spare wheel

Check the tyres regularly for signs of damage
and replace any damaged tyres immediately.
Check wheels and tyres for damage at least
once a month. Check wheels and tyres after
driving off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure. Pay
particular attention to damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on the tyres
R deformation or severe corrosion on the
wheels
Regularly check the tyre tread depth and the
condition of the tread across the whole width of
the tyre (Y page 335). If necessary, turn the
front wheels to full lock to make it easier to
inspect the inner side of the tyre surface.
All wheels must have a valve cap to protect the valve against dirt and moisture. Do not fit any-
thing onto the valve other than the standard
valve cap or other valve caps specially approved
for your vehicle by Mercedes-Benz. Do not fit
any other valve caps or systems, e.g. tyre pres- sure monitors.
Check the pressure of all tyres regularly as well
as prior to long trips. Adjust the tyre pressures
as necessary (Y page 337).
Observe the notes on the emergency spare
wheel (Y page 348).
The service life of a tyre depends on various fac-
tors, including the following:
R driving style
R tyre pressure
R mileage Notes on the tyre tread
G
WARNING
Insufficient tyre tread will reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces, the risk of aquaplaning increases, in particularwhere speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tyre pressure is too high or too low, tyres may exhibit different levels of wear at differ- ent locations on the tyre tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3 mm
R M+S tyres: 4 mm
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached. Selecting, fitting and replacing tyres
G
WARNING
Exceeding the stated tyre load-bearing capa-
city and the approved maximum speed could
lead to tyre damage or the tyre bursting. There is a risk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the
tyre load rating and speed rating required for your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These require-
ments may stipulate a specific tyre type for your
vehicle. Furthermore, the use of a specific tyre
type in certain regions and areas of operation
can be highly beneficial. You can find further
information regarding tyres at specialist tyre
retailers, at qualified specialist workshops or at
any Mercedes-Benz Service Centre.
R Use only tyres and wheels of the same type
and make.
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe here the "MOExtended tyres (tyres
with run-flat characteristics)" section
(Y page 318).
R Fit only tyres of the correct size onto the
wheels.
R Run in new tyres at moderate speeds for the
first 100 km. They reach their full perform-
ance only after this distance. Operation
335Wheels and tyres Z

R
Do not drive with tyres that have too little
tread depth. This significantly reduces trac-
tion on wet roads (aquaplaning).
R Replace the tyres after six years at the latest,
regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 348). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat char- acteristics), you can continue to drive your vehi-
cle even if there is a total loss of pressure in one or more tyres.
MOExtended tyres may be used only in conjunc-tion with an activated tyre pressure loss warning
system or with an activated tyre pressure mon-
itor and only on wheels specifically tested by
Mercedes-Benz.
Notes on driving with MOExtended tyres with a
flat tyre (Y page 318).
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that
do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained from a
qualified specialist workshop. Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 342). Driving with summer tyres
At temperatures below +7 †, summer tyres lose
elasticity and therefore traction and braking
power. Change the tyres on your vehicle to
M+S tyres. Using summer tyres at very cold
temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage. G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damageand replace any damaged tyres immediately. M+S tyres
G
WARNING
M+S tyres with a tyre tread depth of less than 4 mm are not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
M+S tyres with a tread depth of less than
4 mm must be replaced.
At temperatures below +7 †, use winter tyres or all-season tyres. Both types of tyre are identified
by the M+S marking.
Only winter tyres bearing the isnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions. Only these tyres will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tyres have been devel-
oped specifically for driving in snow.
Use M+S tyres of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tyres you have fit-
ted.
If you fit M+S tyres that have a lower maximum
permissible speed than that of the vehicle, affix
an appropriate warning label in the driver's field
of vision. This can be obtained at a qualified
specialist workshop.
Under these circumstances, you should also
restrict the maximum design speed of the vehi- cle using the permanent limiter to the maximumpermissible speed for the M+S tyres
(Y page 180). 336
Winter operationWheels and tyres

When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 337).
X Restart the tyre pressure loss warning system
(Y page 339).
X Restart the tyre pressure monitor
(Y page 341).
Information about driving with an emergency
spare wheel (Y page 348). Snow chains
G
WARNING
If snow chains are fitted to the rear wheels,
they may scrape against the vehicle body or
chassis components. This could cause dam-
age to the vehicle or the tyres. There is a risk of an accident.
To avoid hazardous situations:
R never fit snow chains on the rear wheels
R always fit snow chains in pairs to the front
wheels.
! Vehicles with steel wheels:
if you fit snow
chains on steel wheels, you may damage the
hub caps. Remove the hub caps from the rel- evant wheels before fitting the snow chains.
For safety reasons, Mercedes-Benz recom-
mends that you use only snow chains that have been approved for Mercedes-Benz or that are of
an equivalent standard of quality. For more
information, please contact a qualified special-
ist workshop.
If you wish to fit snow chains, please bear the
following points in mind:
R snow chains cannot be fitted to all wheel/tyre
combinations. Permissible wheel-tyre combi- nations (Y page 347).
R use snow chains only if the road surface is
completely snow-covered. Remove the snow
chains as soon as possible when you come to
a road that is not snow-covered.
R local regulations may restrict the use of snow
chains. Observe the appropriate regulations if you wish to fit snow chains.
R do not exceed the maximum permissible
speed of 50 km/h.
R never use Parking Pilot when snow chains are
fitted (Y page 197). You may wish to deactivate ESP
®
when pulling
away with snow chains fitted. This allows the
wheels to spin in a controlled manner, achieving increased propulsive force (cut).

Tyre pressure specifications
G
WARNING
Underinflated or overinflated tyres pose the
following risks:
R the tyres may burst, especially as the load
and vehicle speed increase.
R the tyres may wear excessively and/or
unevenly, which may greatly impair tyre
traction.
R the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Observe the recommended tyre pressure and check the tyre pressure of all the tyres includ-
ing the spare wheel:
R at least every two weeks
R when the load changes
R before embarking on a longer journey
R for changed operating conditions, e.g. off-
road driving
If necessary, correct the tyre pressure. G
WARNING
If you fit unsuitable accessories onto tyre
valves, the tyre valves may be overloaded and malfunction, which can cause tyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can also result in tyre pressure loss. There is a risk of accident. Tyre pressure
337Wheels and tyres
Z

Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
your vehicle onto the tyre valve. G
WARNING
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in a tyre
blow-out. There is a risk of accident.
R Check the tyre for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days.
The recommended tyre pressures for various
operating conditions can be found on the tyre
pressure table on the fuel filler flap
(Y page 164).
Operation with an emergency spare wheel:
information on operation with an emergency
spare wheel can be found in the general notes in the "Emergency spare wheel" section
(Y page 348).
Operation with a trailer: the applicable value
for the rear axle is the maximum value stated in the tyre pressure table inside the fuel filler flap.
Additionally, the tyre pressure table may also
state tyre pressures for different load condi-
tions. These are defined in the table as different numbers of passengers and amounts of lug-
gage. The actual number of seats may vary; for
more information, please refer to the vehicle
documents.
If tyre sizes are not specified, the tyre pressures
stated on the tyre pressure table apply for all
tyres approved at the factory for this vehicle. If a tyre size precedes a tyre pressure, the fol-
lowing tyre pressure information is valid only for that tyre size.
Use a suitable pressure gauge to check the tyre
pressure. The outer appearance of a tyre does
not give any reliable indication of the tyre pres-
sure. On vehicles fitted with the electronic tyre
pressure monitor, you can also check the tyre
pressure using the on-board computer.
If possible, correct tyre pressures only when the
tyres are cold.
The tyres are cold:
R if the vehicle has been parked with the tyres
out of direct sunlight for at least three hours
and
R if the vehicle has been driven less than
1.6 km
Depending on the ambient temperature, the
vehicle speed and the load on the tyres, the tyre temperature and thus the tyre pressure changes by approximately 10 kPa (0.1 bar/1.5 psi) per
10 †. Take this into account when checking the
pressure of warm tyres. Correct the tyre pres-
sure only if it is too low for the current operating
condition.
Driving with a tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have a negative effect on handling character-
istics and thus driving safety (e.g. aquaplan-
ing)
The tyre pressure values given for low loads are minimum values that offer you good driving
comfort characteristics.
However, you can also use the values given for
higher loads. These are permissible and will not
adversely affect the running of the vehicle. 338

(Y page 256).
If the position of the wheels on the vehicle is
changed, the tyre pressures may be displayed in
the wrong positions for a short time. After a few minutes of driving, this is rectified and the tyre
pressures are displayed in the correct positions. Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tyre pressures as the reference values
for monitoring. In most cases, the tyre pressure monitor will automatically detect the new refer- ence values after you have changed the tyre
pressure. However, you can also set reference
values manually as described here. The tyre
pressure monitor then monitors the new tyre
pressure values.

sors. Wheel and tyre combinations
General notes
You can ask for information regarding permitted
wheel/tyre combinations at a Mercedes-Benz
Service Centre.
You should regularly check the pressure of all
your tyres, including the emergency spare
wheel, particularly prior to long trips, and cor-
rect the pressure as necessary (Y page 337).
The value on the wheel is valid.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres and wheels
which have been approved by Mercedes-Benz specifically for your vehicle.
These are specially adapted to the control
systems, such as ABS or ESP ®
and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz. Only use tyres, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with a load, tyre dimension variations
could cause the tyres to come into contact
with the bodywork and axle components. This
could result in damage to the tyres or the
vehicle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tyres, wheels or accessories other than those tested and
approved.
Further information about wheels, tyres and
approved combinations can be obtained from
any qualified specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected on
retreaded tyres. As a result, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tyres are fitted. Do not fit used tyres if you
have no information about their previous
usage.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll comfort and suspension comfort are reduced and therisk of damage to the wheels and tyres as a
result of driving over obstacles increases.
The recommended tyre pressures for various
operating conditions can be found on the tyre
pressure table on the fuel filler flap. Further
information on tyre pressure (Y page 337).
Check tyre pressures regularly and only when
the tyres are cold.
Notes on the vehicle equipment – always fit the
vehicle:
R with tyres of the same size across an axle
(left/right)
R with the same type of tyre (summer tyres,
MOExtended tyres, winter tyres)
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe the "MOExtended tyres (tyres with
run-flat characteristics)" section
(Y page 318).
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that Wheel and tyre combinations
