3 depth and the condition of the tread
across the entire width of all tyres. If nec
-
essary, turn the steering wheel so that
you can see the tyre tread more easily.
You could otherwise lose control of the
vehicle and cause an accident due to the
reduced grip of the tyres on the road. Tyre pressures
G
Risk of accident
Tyre pressure that is either too high or too
low has a negative effect on the vehicle’ s
active safety, which could lead you to caus e
an accident. You should therefore regularly
check the pressure of all your tyres (includ -
ing the spare tyre*), particularly prior to
long trips, and correct the pressure as nec -
essary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure.
If the vehicle is to be heavily laden or driven
at high speeds, the tyre pressure must be
adapted according to the specifications given
in the fuel filler flap (Y page 204). Use the highest specified tyre pressure for
the spare wheel*
. G
Risk of accident
Should the tyre pressure drop repeatedly:
R Check the tyre for foreign bodies.
R Check whether the wheel is losing air or
the valve is leaking .
Tyre pressure that is too low has a negative
effect on the vehicle’s active safety, which
could lead to your causing an accident .
Tyre pressure changes by approximately
0.1 bar for every 10 °C change in ambient
temperature.
If you measure the tyre pressure in enclosed
spaces where the temperature differs from
the outside temperature, you will have to cor-
rect the measured value accordingly.
When the vehicle is driven, the tyre tempera-
ture, and with it the tyre pressure, will
increase depending on the road speed and
the load on the tyres.
Therefore, you should only correct tyre pres-
sures when the tyres are cold.
The pressure of warm tyres should only be
corrected if it is too low for the current oper-
ating conditions. You will find a table of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
Driving with tyre pressure that is too high or
too low can:
R
shorten the service life of the tyres
R cause increased tyre damag e
R have a negative effect on handling charac-
teristics (e.g. by causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics .
You can, however, also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle.
Also check the tyre pressure of the spare
wheel* . H

4 Tyre pressure loss warning system
G
Risk of accident
The tyre pressure loss warning system*
does not warn you of an incorrectly set tyre
pressure. The table on the inside of the fue l
filler flap will help you decide whether the
tyre pressures should be corrected.
The tyre pressure loss warning system*
does not replace the need to regularly
check your vehicle's tyre pressures, since
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
pressure, e.g. following penetration by a
foreign object.
In the event of a sudden loss of pressure,
bring the vehicle to a halt by braking care-
fully. Do not make any sudden steering
movements when doing so.
While the vehicle is in motion, the tyre pres-
sure loss warning system* monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the spee d
of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning
message will appear in the multi-function dis-
play.
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 grave l
R you adopt a very sporty driving style (cor -
nering 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 th e
vehicle or on the roof)
Restarting the tyre pressure loss warn-
ing system* Restart the tyre pressure loss warning sys-
tem* if you have
:
R changed the tyre pressure
R changed the wheels or tyre s
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler fla pto ensure that the tyre pressure in all fou
r
tyres is set correctly for the operating con-
ditions concerned .
X Also observe the notes in the section on
tyre pressures (Y page 213). G
Risk of accident
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, thes e
incorrect values will be monitored.
A tyre with insufficient pressure results in
an instability of the vehicle when driving,
thus increasing the risk of an accident .

G
Risk of accident
Interchange the front and rear wheels only
if they have the same dimensions, for exam-
ple size, offset, etc.
After every wheel interchange/change,
have the tightening torque checked at a
qualified specialist workshop that has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The wheels could work loose if they are not
tightened to a tightening torque of
130 Nm.
For safety reasons, Mercedes-Benz recom -
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wheels may be interchanged every 5,000
km to 10,000 km depending on the degree of
tyre wear, provided that the vehicle has the
same size front and rear tyres. Do not reverse
the direction of tyre rotation. Operation

7 Snow chains
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains which
have been specially approved for your vehicle
by Mercedes-Benz or are of a correspondin g
standard of quality.
! Information about the use of snow chain
compatible AMG winter tyres is applicable
for AMG tyres. Use of snow chains is only
permissible with these tyres.
If you intend to fit snow chains, please bear
the following points in mind:
R Snow chains cannot be fitted on all wheel /
tyre combinations .
R Snow chains cannot be fitted to emergency
spare wheels, e.g. on a "Minispare" emer-
gency spare wheel .
R Always fit snow chains on both the rea r
wheels, even on vehicles with 4MATIC* .
Comply with the manufacturer's installa-
tion instructions.
! If snow chains are fitted to the fron t
wheels, they may come into contact with
the bodywork and axle components when
the vehicle is in motion and damage th e
tyre or the vehicle. Do not exceed the maximum permissibl
e
speed of 50 km/h.
i You may wish to deactivate ES P®
when
pulling away with snow chains fitted
( Y page 68). This way you can allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action). Winter driving
G
Risk of accident
Do not shift down for additional engine
braking on a slippery road surface. Thi s
could cause the drive wheels to lose thei r
grip and the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission: engage
neutral.
X Vehicles with automatic transmission*:
shift the selector lever to N.
X Try to bring the vehicle under control using
corrective steering. Driving tips
Rolling with the engine switched off
G
Risk of accident
Never switch the engine off while the vehi-
cle is in motion.
There is no power assistance for the steer-
ing and the service brake when the engine
is not running.
You will require considerably more effort to
steer and brake and you could therefore
lose control of the vehicle and cause an
accident. Brakin

On long and steep downhill gradients you
must select a lower gear in good time, or on
vehicles with automatic transmission*, select
the shift range 1,2 or 3.
i This also applies if you have activated
cruise control* or Speedtronic*.
This uses the braking effect of the engine and
you will not have to brake to such an exten t
to maintain the same speed. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly. If you need additional braking ,
depress the brake pedal repeatedly rather
than continuously. G
Risk of accident
Never depress the brake pedal continu -
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely. Driving tips
R
Maintain a greater distance from the vehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine
and with it its gradient-climbing capability
decrease with increasing altitude.
If the trailer swings from side to side:
X Do not accelerate.
X Do not counter-steer.
X Brake if necessary. G
Risk of accident
On no account should you attempt to dra w
the vehicle/trailer combination out by
increasing speed. Folding in the ball couplin

age the surfaces.
X Wipe plastic parts with a damp, lint-free
cloth (e.g. a microfibre cloth).
X Light soiling: use a low-foaming soap (e.g .
a light liquid hand soap) diluted in water.
X Heavy soiling: use a cleaning agent that is
solvent-free and non-corrosive. Mercedes-
Benz recommends that you use a
Mercedes-Benz cleaning product for this
purpose.
Cleaning the steering wheel boss and

Moisten a clean lint-free cloth with water.
X Clean the plastic parts and the dashboard.
X If particularly dirty, use a mild detergent. G
Risk of injury
Do not use cleaners and cockpit care
sprays containing solvents to clean the
cockpit and steering wheel boss. Cleaners
containing solvents cause the surface to
become porous and in the event of an air-
bag being triggered, plastic parts that have
become loose could cause considerable
injuries.
Leather upholstery* !
Cleaning
R Clean genuine leather covers using a
damp cloth, then wipe these down after -
wards using a dry cloth. When doing this,
make sure that the leather does not
become soaked. For leather care, you
should use leather care foam A 001 98 6
59 71 10. You can purchase this at any
Mercedes-Benz Service Centre.
R Clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e. g. Pril).
R Clean fabric covers with a micro-fibr e
cloth moistened with a solution contain-
ing 1% detergent (e .g. Pril). When clean-
ing, take care not to rub too vigorously and always wipe entire seat sections to
avoid leaving visible lines. Leave the sea
t
to dry afterwards. Cleaning results
depend on the type of dirt and how long
it has been there.
R Clean Alcantara covers with a damp
cloth. Make sure you wipe entire seat
sections to avoid leaving visible lines.
i Note that leather covers are subject to a
natural ageing process because they are a
natural product and may react in different
ways (e.g. increased formation of wrinkles)
to certain environmental influences (such
as high humidity, intense heat).
Note that regular care is essential to ensure
that the quality (both appearance and com-
fort) of the covers is retained in the long
term .
