2015 MERCEDES-BENZ GLE COUPE warning

Tyre pressure loss warning system
General notes While the vehicle is in motion, the tyre pressure
loss warning system monitors the set tyre pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in a tyre. If the speed of rotation of a wheel changes as a result of a loss of pressure,
a corresponding warning message will appear in
the multifunction display.
You can recognise the tyre pressure loss warn-
ing by the Run Flat Indicator active

Restart with OK
Restart with OK message which appears in
the Serv.
Serv. menu of the multifunction display.
Information on the message display can be
found in the "Restarting the tyre pressure loss
warning system" section (Y page 353).
Important safety notes The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe the notes on the recommended tyre pressure
(Y page 351).
The tyre pressure loss warning does not replace the need to regularly check the tyre pressures.
An even loss of pressure on several tyres at the
same time cannot be detected by the tyre pres-
sure loss warning system.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the tyre is penetrated by a foreign object. In the event of
a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering
manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt a very sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration).
R you are towing a very heavy or large trailer.
R you are driving with a heavy load (in the vehi-
cle or on the roof). Restarting the tyre pressure loss warn-
ing system Restart the tyre pressure loss warning system if
you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, make sure that the tyre
pressures are set properly on all four tyres for
the respective operating conditions. The rec-
ommended tyre pressures can be found in the
tyre pressure table on the fuel filler flap.
The tyre pressure loss warning system can
only give reliable warnings if you have set the correct tyre pressure. If an incorrect tyre
pressure is set, these incorrect values will be
monitored.

restart will continue to be monitored. Tyre pressure monitor
General notes If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that moni-
tor the tyre pressures in all four tyres. The tyre
pressure monitor warns you if the pressure
drops in one or more of the tyres. The tyre pres- sure monitor only functions if the corresponding
sensors are fitted to all wheels.
Information on tyre pressures is shown in the
multifunction display. After a few minutes of
driving, the current tyre pressure of each tyre is
shown in the Serv.
Serv. menu of the multifunction
display, see illustration (example). For further information on displaying this mes-
sage, refer to the "Checking the tyre pressure
electronically" section (Y page 354).
Important safety notes It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating situation
(Y page 351). Note that the correct tyre pres-
sure for the current operating situation must
first be taught-in to the tyre pressure monitor. If
there is a substantial loss of pressure, the warn- ing threshold for the warning message is aligned
to the reference values taught-in. Restart the
tyre pressure monitor after adjusting to the cold tyre pressure (Y page 355). The current pres-
sures are saved as new reference values. This
will ensure that a warning message will only
appear if the tyre pressure drops significantly.
The tyre pressure monitor does not warn you of
an incorrectly set tyre pressure. Observe the
notes on the recommended tyre pressure
(Y page 351). The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the tyre is penetrated by a foreign object. In the event of
a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering
manoeuvres.
The tyre pressure monitor has a yellow warning
lamp in the instrument cluster for indicating a
pressure loss or malfunction. Depending on how
the warning lamp flashes or lights up, a tyre
pressure that is too low or a malfunction in the
tyre pressure monitor is indicated:
R if the warning lamp is lit continuously, the tyre
pressure on one or more tyres is significantly
too low. The tyre pressure monitor is not mal- functioning.
R if the warning lamp flashes for around a
minute and then remains lit constantly, the
tyre pressure monitor is malfunctioning.
In addition to the warning lamp, a message
appears in the multifunction display. Observe
the information on display messages
(Y page 279).
It may take up to ten minutes for a malfunction
of the tyre pressure monitor to be indicated. A
malfunction will be indicated by the tyre pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
fault has been rectified, the tyre pressure warn- ing lamp goes out after you have driven for a few
minutes.
The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at a filling station using a pressure gauge.
The tyre pressures shown by the on-board com- puter refer to those measured at sea level. At
high altitudes, the tyre pressure values indica-
ted by a pressure gauge are higher than those
shown by the on-board computer. In this case,
do not reduce the tyre pressures.
The operation of the tyre pressure monitor can
be affected by interference from radio transmit-
ting equipment (e.g. radio headphones, two-way radios) that may be being operated in or near the vehicle.

multifunction display, the tyre pressure in at
least one tyre has dropped significantly. The
tyres must be checked.
R If the Warning tyre defect

appears in the multifunction display, the tyre
pressure in at least one tyre has dropped sud- denly. The tyres must be checked.
If the wheel positions on the vehicle are inter-
changed, the tyre pressures may be displayed
for the wrong positions for a short time. After a
few minutes of driving, this is rectified and the
tyre pressures are displayed for 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.

tance" section (Y page 333). Information on
driving with MOExtended tyres in the event of a flat tyre can be found under "Breakdown assis-
tance" (Y page 333).
Vehicles with an emergency spare wheel: in
the event of a flat tyre, fit the emergency spare
wheel according to the description under "Fit-
ting a wheel" (Y page 357). Interchanging the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions. The wheel brakes or suspension components may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with a tyre pressure mon-
itor, electronic components are located in the wheel.
Tyre-fitting tools should not be applied in thearea of the valve, as this could damage the
electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
Interchanging the front and rear wheels of dif-
fering dimensions can render the general oper-
ating permit invalid.
Observe the instructions and safety notes in the "Fitting a wheel" section (Y page 357).356

WARNING
If you do not position the jack correctly at the appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
Observe the following when raising the vehi- cle:
R only use the vehicle-specific jack that has
been tested and approved by Mercedes-Benz
to raise the vehicle. If the jack is used incor-
rectly, it could tip over while the vehicle is
raised.
R the jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed. It is not permissible to use it to per- form maintenance work under the vehicle.
R avoid changing the wheel on uphill and down-
hill slopes.
R before raising the vehicle, safeguard it from
rolling away by applying the parking brake and positioning wheel chocks. Do not release theparking brake while the vehicle is raised. R
the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large,
flat load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
R do not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack will not
be able to achieve its load-bearing capacity
due to the restricted height.
R make sure that the distance between the
underside of the tyres and the ground does
not exceed 3 cm.
R do not place your hands or feet under the
raised vehicle.
R do not lie under the vehicle.
R do not start the engine when the vehicle is
raised.

Important safety notes
G
WARNING
The wheel/tyre dimensions and the tyre type of the spare wheel/emergency spare wheel
and the wheel to be replaced may differ. Fit-
ting a spare wheel/emergency spare wheel
may severely impair the driving characteris-
tics. There is a risk of accident.
To prevent hazardous situations:
R Adapt your driving style accordingly and
drive carefully.
R Never fit more than one spare wheel/emer-
gency spare wheel if the dimensions are
different to those of the wheel being
replaced.
R Only use a spare wheel/emergency spare
wheel briefly if the dimensions are different to those of the wheel being replaced.
R Do not switch off ESP ®
.
R Have the spare wheel/emergency spare
wheel in question replaced at the nearest
qualified specialist workshop. Make sure
that the wheel/tyre dimensions and tyre
type are correct. When using an emergency spare wheel or spare
wheel of a different size, you must not exceed
the maximum speed of 80 km/h.
Snow chains must not be fitted to emergency
spare wheels. General notes
Fitting the emergency spare wheel is described under "Fitting a wheel" (Y page 357).
You should regularly check the pressure of the
emergency spare wheel, particularly prior to
long trips, and correct the pressure as neces-
sary (Y page 351). The value on the wheel or as
given in the "Wheels and tyres" section is valid
(Y page 371).
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the
time restriction on use as well as the speed lim- itation specified on the emergency spare wheel.
Replace the tyres after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
i If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning
system or the tyre pressure monitor cannot
function reliably. Only restart the tyre pres-
sure loss warning system or tyre pressure
monitor when the defective wheel has been
replaced with a new wheel.
