2017 MERCEDES-BENZ GLA-Class Owner's Manual

XTighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated (:
to A). The specified tightening torque is
96 lb-ft (130 Nm).
XTurn the jack back to its initial position.
XStow the jack and the rest of the vehicle
tools in the vehicle again.
XCheck the tire pressure of the newly moun-
ted wheel and adjust it if necessary.
Observe the recommended tire pressure
(
Ypage 343).
When you are driving with the collapsible
spare wheel mounted, the tire pressure loss
warning system or the tire pressure monitor
cannot function reliably. Only restart the tire
pressure loss warning system or tire pressure
monitor when the defective wheel has been
replaced with a new wheel.
Vehicles with a tire pressure control sys-
tem: all installed wheels must be equipped
with functioning sensors.

General notes
!
For safety reasons, Mercedes-Benz rec-
ommends that you only use tires and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle. These tires have been specially adapted for
use with the control systems, such as ABS
or ESP
®, and are marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended
(tires featuring run-flat characteristics)
RMO1 = Mercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, tire dimen-
sion variations could cause the tires to
come into contact with the bodywork and
axle components. This could result in dam-
age to the tires or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tires,
wheels or accessories other than those tes-
ted and approved.
Information on tires, wheels and approved
combinations can be obtained from any
qualified specialist workshop.
!Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz, since pre-
vious damage cannot always be detected
on retreaded tires. As a result, Mercedes-
Benz cannot guarantee vehicle safety if
retreaded tires are mounted. Do not mount
used tires if you have no information about
their previous usage.
Overview of abbreviations used in the follow-
ing tire tables:
RBA: both axles
RFA: front axle
RRA: rear axle

The recommended pressures for various
operating conditions can be found:
Ron the Tire and Loading Information placardon the B-pillar on the driver's side
Rin the tire pressure table in the fuel filler flap
Observe the notes on recommended tire
pressures under various operating conditions
(
Ypage 343).
Check tire pressures regularly, and only when
the tires are cold. Comply with the mainte-
nance recommendations of the tire manufac-
turer in the vehicle document wallet.
Notes on the vehicle equipment – always
equip the vehicle with:
Rwith tires of the same size on a given axle
(left and right)
Rthe same type of tires at a given time (sum-
mer tires, winter tires, MOExtended tires)
Exception: it is permissible to install a dif-
ferent type or make in the event of a flat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section
(
Ypage 323).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if
you mount tires that do not feature run-flat
properties, e.g. winter tires. A TIREFIT kit may
be obtained from a qualified specialist work-
shop.
iNot all wheel and tire combinations are
available at the factory for all countries.
iThe following pages contain information
on approved wheel rims and tire sizes for
equipping your vehicle with winter tires.
Winter tires are not available at the factory
as standard equipment or optional extras.
If you want to equip your vehicle with
approved winter tires, it may be necessary
to obtain wheel rims in the corresponding
size. The size of the approved winter tires
may differ from the standard tires. This is
dependent on the model and the equip-
ment installed at the factory. The tires and wheel rims, as well as further
information, can be obtained at a qualified
specialist workshop.

Useful information
i
This Operator's Manual describes all
models and all standard and optional equip-
ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
iRead the information on qualified special-
ist workshops (
Ypage 25).
Information regarding technical data
i
The data stated here specifically refers to
a vehicle with standard equipment. Consult an authorized Mercedes-Benz Center for
the data for all vehicle variants and trim
levels.
Vehicle electronics
Retrofitting two-way radios and
mobile phones (RF transmitters)
GWARNING
The electromagnetic radiation from modified
or incorrectly retrofitted RF-transmitters can
interfere with the vehicle electronics. This can compromise the operational safety of the
vehicle. There is a risk of an accident.
You should have all work to electrical and
electronic equipment carried out at a qualified
specialist workshop.
GWARNING
The electromagnetic radiation from incor-
rectly operated RF transmitters can interfere
with the vehicle electronics, for example:
Rif the RF transmitter is not connected with
an exterior antenna
Rthe exterior antenna has been installed
incorrectly or is not a low-reflection type
This can compromise the operational safety
of the vehicle. There is a risk of an accident.
Have the low-reflection exterior antenna
mounted at a qualified specialist workshop.
When operating RF transmitters in the vehi-
cle, always connect them with the low-reflec-
tion exterior antenna.
!The operating permit may be invalidated if
the instructions for installation and use of
RF transmitters are not observed.
In particular, the following conditions must
be complied with:
Ronly approved wavebands may be used.
Rcompliance with the maximum permissi-
ble output in these wavebands is
required.
Ronly approved antenna positions may be used.
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior antenna
takes into account current scientific discus-
sions relating to the possible health hazards
that may result from electromagnetic fields.
