2016 MERCEDES-BENZ CLA COUPE snow chains

Parking tips:
R on narrow roads, drive as closely as possible
past the parking space
R parking spaces that are littered or overgrown
might be identified or measured incorrectly
R parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly
R snowfall or heavy rain may lead to a parking
space being measured inaccurately
R pay attention to the Parking Assist
PARKTRONIC warning messages
(Y page 178) during the parking procedure
R you can intervene in the steering procedure to
correct it at any time. Parking Pilot will then be cancelled
R when transporting a load that protrudes from
your vehicle, you should not use Parking Pilot
R never use Parking Pilot when snow chains are
fitted
R make sure that the tyre pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle
Use Parking Pilot for parking spaces that are:
R parallel or at right angles to the direction of
travel
R on straight roads, not bends
R on the same level as the road, e.g. not on the
pavement
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached a trailer to your vehicle, you
should not use Parking Pilot. Once the electrical
connection is established between your vehicle
and the trailer, Parking Pilot is no longer availa- ble. Parking Assist PARKTRONIC is deactivated
for the rear area.
Detecting parking spaces Objects located above the detection range of
Parking Pilot will not be detected when the park-
ing space is measured. These are not taken into
account when the parking procedure is calcula- ted, e.g. overhanging loads, tail sections or load-
ing ramps of goods vehicles. G
WARNING
If there are objects above the detection range:
R Parking Pilot may steer in too early
R the vehicle may not stop in front of these
objects
This could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop and deactivate Parking Pilot.
Further information on the detection range
(Y page 177).
Parking Pilot does not assist you parking in
spaces at right angles to the direction of travel if:
R two parking spaces are located directly next
to one another
R the parking space is directly next to a low
obstacle such as a low kerb
R you forward-park
Parking Pilot does not assist you parking in
spaces parallel or at right angles to the direction of travel if:
R the parking space is on a kerb
R the system reads the parking space as being
blocked, such as by foliage or grass paving
blocks
R the area is too small for the vehicle to
manoeuvre into
R the parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer :

Parking Pilot is activated automatically when
driving forwards. The system is operational at
speeds of up to approximately 35 km/h. While
in operation, the system independently locates
and measures parking spaces on both sides of
the vehicle. Driving systems

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 only use 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. Permitted wheel/tyre
combinations (Y page 323).
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 do not use Parking Pilot when snow chains are
fitted (Y page 180). You may wish to deactivate ESP
®
when pulling
away with snow chains fitted (Y page 70). 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.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
your vehicle onto the tyre valve. Tyre pressure

Restart with OK
Restart with OK message which appears in
the multifunction display in the Serv.
Serv.menu.
Information on the message display can be
found in the "Restarting the tyre pressure loss
warning system" section (Y page 315).
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 313).
The tyre pressure loss warning system does not
replace the need to regularly check the tyre
pressure. An even loss of pressure on several
tyres at the same time cannot be detected by
the tyre pressure loss warning system.
The tyre pressure loss warning system is not
able to warn you of a sudden loss of air, e.g. if the
tyre is penetrated by a foreign object. In the
event of a sudden loss of air, 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 on your vehicle
R road conditions are wintry
R you are driving on a loose surface (e.g. 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, this incorrect value will be
monitored.
X Observe the notes in the section on tyre pres-
sures (Y page 313).
X Make sure that the key is in position 2in the
ignition lock (Y page 133).

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 vehicle's maximum design speed of
80 km/h.
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 313).
The value on the wheel is valid.
Snow chains must not be fitted to emergency
spare wheels. General notes
You can ask for information regarding permitted
emergency spare wheels at a Mercedes-Benz
Service Centre.
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.
If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning sys- tem or the tyre pressure monitor cannot func-
tion reliably. Restart the tyre pressure loss warn-
ing system or tyre pressure monitor only once
the defective wheel has been replaced with a
new wheel.
Vehicles with tyre pressure monitor: after an
emergency spare wheel has been fitted, the sys- tem may still display the tyre pressure of the
removed wheel for a few minutes. The value dis-
played for the position where the emergency
spare wheel is fitted is not the same as the cur- rent tyre pressure of the emergency spare
wheel. Removing the emergency spare wheel
