2016 MERCEDES-BENZ GLA tire pressure

If a tire pressure of 180 kPa (1.8 bar/26 psi)
has not been attained after five minutes, see
"Tire pressure not reached" ( Y
page 326).
If tire sealant has escaped, clean it off affec-
ted areas as quickly as possible. Use plain
water if possible.
If your clothes are soiled with tire sealant,
have them cleaned with perchloroethylene at
a dry cleaner as soon as possible.
Tire pressure not reached If a pressure of 180 kPa (1.8 bar/26 psi) has
not been attained after five minutes: X
Switch off the tire inflation compressor. X
Unscrew the filler hose from the valve of
the faulty tire.
Note that tire sealant may escape when you
unscrew the filler hose. X
Very slowly drive forwards or reverse
approximately 30 ft (10 m). X
Pump up the tire again.
After a maximum of five minutes the tire
pressure must be at least 180 kPa (1.8 bar/
26 psi).
G WARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and a tire
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tire pressure reached
G WARNING
A tire temporarily sealed with tire sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed the specified maximum speed with a tire that
has been repaired using tire sealant.
The maximum permissible speed for a tire
sealed with tire sealant is 50 mph (80 km/h).
The upper part of the TIREFIT sticker must be
affixed to the instrument cluster in the driv-
er's field of vision.
! Residue from the tire sealant may come
out of the filler hose after use. This could
cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.
H Environmental note
Have the used tire sealant bottle disposed of
professionally, e.g. at a qualified specialist
workshop.
If a tire pressure of 180 kPa (1.8 bar/26 psi)
has been attained after five minutes: X
Switch off the tire inflation compressor. X
Unscrew the filler hose from the valve of
the faulty tire. X
Stow the tire sealant bottle and the tire
inflation compressor. X
Pull away immediately .X
Stop after driving for approximately ten
minutes and check the tire pressure with
the tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
G WARNING
If the required tire pressure is not reached
after driving for a short period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.

Operation
Information on driving
Check the tire pressure when the vehicle is
heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you sus-
pect that a tire is defective, reduce your
speed immediately. Stop the vehicle as soon
as possible to check the wheels and tires for
damage. Hidden tire damage could also be
causing the unusual handling characteristics.
If you find no signs of damage, have the tires
and wheels checked at a qualified specialist
workshop.340
Operation
Wheels and tires

When parking your vehicle, make sure that
the tires do not get deformed by the curb or
other obstacles. If they cannot be avoided,
drive over obstacles such as curbs slowly and
at an obtuse angle. Otherwise, you may dam-
age the wheels or tires.
Regular checking of wheels and tires
G WARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Check wheels and tires for damage at least
once a month. Check wheels and tires after
driving off-road or on rough roads. Damaged
wheels can cause a loss of tire pressure. Pay
particular attention to damage such as: R
cuts in the tires R
punctures R
tears in the tires R
bulges on tires R
deformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width
of the tire ( Y
page 341). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tire surface.
All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
mount anything onto the valve other than the
standard valve cap or other valve caps
approved by Mercedes-Benz for your vehicle.
Do not use any other valve caps or systems,
e.g. tire pressure monitoring systems.
Regularly check the pressure of all the tires
particularly prior to long trips. Adjust the tire
pressure as necessary ( Y
page 343). The service life of tires depends, among other
things, on the following factors: R
driving style R
tire pressure R
distance covered
Notes on tire tread
G WARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driving con-
ditions. There is a risk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for: R
Summer tires:

vide the best possible grip in wintry road con-
ditions. Only these tires will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter. These tires have
been developed specifically for driving in
snow.
Use M+S tires of the same make and tread on
all wheels to maintain safe handling charac-
teristics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
When you have mounted the M+S tires: X
Check the tire pressures ( Y
page 343).X
Restart the tire pressure loss warning sys-
tem (Canada) ( Y
page 347) or restart the
tire pressure monitor (USA) ( Y
page 350).
Snow chains
G WARNING
If snow chains are mounted on the rear
wheels, the snow chains could cause abrasion
to the vehicle body or to chassis components.
This could cause damage to the vehicle or the
tires. There is a risk of an accident.
To avoid hazardous situations: R
never mount snow chains on the rear
wheels R
only mount snow chains in pairs on the
front wheels.
! On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and
tire combinations" section under "Tires and
wheels".
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle
by Mercedes-Benz, or are of a corresponding
standard of quality. For more information,
please contact a qualified specialist work-
shop. If you intend to mount snow chains, please
bear the following points in mind: R
Snow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel-tire combinations ( Y
page 367).R
Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as possi-
ble when you come to a road that is not
snow-covered. R
Local regulations may restrict the use of
snow chains. Observe the appropriate reg-
ulations if you wish to mount snow chains. R
Do not exceed the maximum permissible
speed of 30 mph (50 km/h). R
When snow chains are installed, never use
Active Parking Assist ( Y
page 203).
You may wish to deactivate ESP ®
when pull-
ing away with snow chains installed
( Y
page 69). You can thereby allow the wheels
to spin in a controlled manner, achieving an
increased driving force (cutting action).

Important safety notes
G WARNING
Underinflated or overinflated tires pose the
following risks: R
the tires may burst, especially as the load
and vehicle speed increase. R
the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction. R
the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident. Tire pressure 343
Wheels and tires Z

Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel: R
monthly, at least R
if the load changes R
before beginning a long journey R
under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
i The data on the Tire and Loading Infor-
mation placard and tire pressure table
shown here are examples. Tire pressure
specifications are vehicle-specific and may
deviate from the data shown here. The tire
pressure specifications that are valid for
your vehicle can be found on the Tire and
Loading Information placard and tire pres-
sure table on the vehicle.
General notes The recommended tire pressures for the tires
mounted at the factory can be found on the
labels described here.
Further information on tire pressures can be
obtained at a qualified specialist workshop.
Tire and Loading Information placard
C
Recommended tire pressures
The Tire and Loading Information placard is
on the B-pillar on the driver's side
( Y
page 351).
The Tire and Loading Information placard con-
tains the recommended tire pressures for cold tires. The recommended tire pressures
are valid for the maximum permissible load
and up to the maximum permissible vehicle
speed.
Tire pressure table The tire pressure table is on the inside of the
fuel filler flap. It shows the tire pressure for all
tires permitted at the factory for this vehicle;
see illustration (example).
The tire pressure table contains the recom-
mended pressures for cold tires for various
operating conditions, i.e. differing load and
speed conditions.
If a tire size precedes a tire pressure, the fol-
lowing tire pressure information is only valid
for that tire size; see illustration (example).
The load conditions "partially laden" and "fully
laden" are defined in the table for different
numbers of occupants and amounts of lug-
gage. The actual number of seats may differ.344
Tire pressure
Wheels and tires

Some tire pressure tables show only the rim
diameters instead of the full tire size, e.g.
R18 . Rim diameter is part of the tire size and
can be found on the tire sidewall
( Y
page 357).
If the tire pressures have been set to the
lower values for lighter loads and/or lower
road speeds, the pressures should be reset to
the higher values: R
if you want to drive with an increased load
and/or R
if you want to drive at higher road speeds
i The tire pressures for increased loads
and/or higher road speeds, shown in the
tire pressure table, may have a negative
effect on driving comfort.
If the tire pressure is not set correctly, this
can lead to an excessive build-up of heat and
a sudden loss of pressure.
For more information, contact a qualified spe-
cialist workshop.
Important notes on tire pressure
G WARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident. R
Check the tire 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.
G WARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire pres-
sure monitors keep the tire valve open. This
can also result in tire pressure loss. There is a
risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve.
Use a suitable pressure gauge to check the
tire pressure. The outer appearance of a tire
does not permit any reliable conclusion about
the tire pressure. On vehicles equipped with
the electronic tire pressure monitor, the tire
pressure can be checked in the on-board
computer.
The tire temperature and pressure increase
when the vehicle is in motion. This is depend-
ent on the driving speed and the load.
Therefore, you should only correct tire pres-
sures when the tires are cold.
The tires are cold: R
if the vehicle has been parked with the tires
out of direct sunlight for at least three
hours and R
if the vehicle has not been driven further
than 1 mile (1.6 km)
The tire temperature changes depending on
the outside temperature, the vehicle speed
and the tire load. If the tire temperature
changes by 18 ‡ (10 †), the tire pressure
changes by approxi mately 10 kPa (0.1 bar/
1.5 psi). Take this into account when check-
ing the pressure of warm tires. Only correct
the tire pressure if it is too low for the current
operating conditions. If you check the tire
pressure when the tires are warm, the result-
ing value will be higher than if the tires were
cold. This is normal. Do not reduce the tire Tire pressure 345
