2012 MERCEDES-BENZ G-CLASS SUV fog light

The hazard warning lamps automatically
switch on if:
R
an airbag is deployed
R the seat belt tensioners are triggered, or
R the vehicle decelerates rapidly from a
speed of more than 70 km/ha nd comes to
a standstill.
The hazard warning lamp switches on auto-
matically if an airbag or the belt tensioners
are triggered and the key is in position 1in
the ignition lock.
The hazard warning lamps switch off auto-
matically if the vehicle reaches a speed of
over 10 km/h again after a full brake appli-
cation.
i The hazard warning lamps still operate if
the ignition is switched off. Cornering light function
The cornering light functio
nimproves the illu-
mination of the road over a wide angle in the
directio nyou are turning, enabling better vis-
ibility in tight bends, for example. The corner-
ing light function can only be activated if the
dipped-beam headlamps are switched on and
the foglamps are switched off.
Active: if you are driving at speeds below
40 km/ha nd switch on the tur nsignal or turn
the steering wheel
Not active: if you are driving at speeds above
40 km/h or switch off the turn signal or turn
the steering wheel to the straight-ahead posi-
tion The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes. Headlamps and turn signals misted
up on the inside
The headlamps and the indicator lamps in the
exterior mirrors may mist up on the inside if
there is high atmospheric humidity.

Switching the windscreen wipers on/
off G
WARNING
The windscreen will not longer be wiped prop-
erly if the wiper blades are worn. This could
prevent you from observing the traffic condi-
tions, thereby causing an accident .Replace the wiper blades twice a year, ideally in spring
and autumn.
! Do not operate the windscreen wipers
when the windscreen/rear window is dry,
as this could damage the wiper blades.
Moreover, dust that has collected on the
windscreen/rear window can scratch the
glass if wiping takes place when the wind-
screen/rear window is dry.
If it is necessary to operate the windscreen
wipers/rear window wiper in dry weather
conditions, always use washer fluid.
! If the windscreen wipers leave smears on
the windscreen/rear window after the vehi-
cle has been washed in an automatic car
wash, this may be due to wax or other res-
idue. Clean the windscreen/rear window
with washer fluid after an automatic car
wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windscreen
becoming dirty in dry weather conditions,
the windscreen wipers may be activated
inadvertently. This could damage the wind-
screen wiper blades or scratch the wind-
screen.
For this reason, you should always switch
off the windscreen wipers in dry weather. Combination switch

New brake pads/linings
New brake pads/brake pads and discs that
have been replaced only achieve optimum
braking effect after several hundred kilome-
tres of driving. Compensate for the reduced
braking effect by applying greate rforce to the
brake pedal.
For safety reasons, Mercedes-Benz recom-
mends that you only have brake pads/linings
fitted to your vehicle which have been
approved for Mercedes-Benz vehicles or
which correspond to an equivalent quality
standard. Brake pads/linings which have not
been approved for Mercedes-Benz vehicles or
which are not of an equivalent quality could
affect your vehicle's operating safety.
High-performance brake system for
AMG vehicles The high-performance brake system is
designed for high loads. This may lead to
noise when braking. This is dependent on:
R speed
R braking force
R environmental conditions, such as temper-
ature and humidity.
The wear of individual components of the
brake system, such as the brake pads/linings
or brake discs, depends on the individual driv-
ing style and operating conditions.
For this reason, it is impossible to state a
mileage (service life) that will be valid under
all circumstances. An aggressive driving style
will lead to high wear. You can obtain further
information about this from your Mercedes-
Benz Service Centre.
Parking brake G
WARNING
If you must brake the vehicle with the parking
brake, the braking distance is considerably
longer and the wheels could lock. This increa-
ses the risk of skidding and an accident. Only use the parking brake to brake the vehi-
cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
When you apply the parking brake to brake
the vehicle, the brake lamps do not light up.
If you drive on wet roads or dirt-covered sur-
faces, road salt and/or dirt could get into the
parking brake.
In order to prevent corrosion and a reduction
in the braking power of the parking brake,
observe the following:
R pull the parking brake upwards with the
release button depressed from time to time
before beginning the journey
(Y page 164).
R drive for approximately 100 m at a maxi-
mum speed of 20 km/h. Tyre traction
G
WARNING
Whereas the vehicle can be fully controlled at
a certain speed on dry roads, you must reduce
your speed on wet or icy roads to achieve the
same road safety. You could otherwise cause
an accident.
Pay particular attention to the road conditions
at temperatures around freezing point.
If ice has formed on the road surface (e.g.
from fog), a thin film of water rapidly forms on
the ice when you brake, considerably reduc-
ing tyre traction. Drive with particular care in
such weather conditions. Driving on slippery surfaces
! If possible, do not let the drive wheels
spin. Otherwise, you could damage the
drive train.
X Engage the differential locks if necessary
(Y page 204). 166
Driving tipsDriving and parking

DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the carriage-
way, because of its narrow width
.The dis-
tance to the vehicle in front will be too short.
Obstructions and stationary vehicles DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turns a corner and reveals
an obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.
Crossing vehicles
DISTRONIC PLUS may detect vehicles that
are crossing your lane by mistake. Activating
DISTRONIC PLUS at traffic lights with cross-
ing traffic, for example, could cause your vehi-
cle to pull away unintentionally. Blind Spot Assist
Important safety notes G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles approaching and driving by with a
speed difference of more than approx-
imately 11 km/h
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else cover-
ing the sensors
R visibility is poor, e.g. due to fog, heavy rain
or snow
R there is a narrow vehicle travelling in front,
e.g. a motorcycle or bicycle
R the road has very wide lanes
R the road has narrow lanes
R you are not driving in the middle of the lane
R there are barriers or other road boundaries
General notes Blind Spot Assist uses a radar sensor system
to monitor both the left and right sides of your
vehicle. It supports you from speeds of
30 km/h. A warning display in the exterior
mirrors draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical
and audible collision warning. For this pur-
pose, Blind Spot Assist uses sensors in the
rear bumper.190

Important safety notes The reversing camera is only an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe manoeuvring and park-
ing. When manoeuvring or parking, make sure
that there are no persons, animals or objects
in the area in which you are manoeuvring.
Under the following circumstances, the
reversing camera will not function, or will
function in a limited manner:
R the rear door is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent light or LED
lighting (the display may flicker) R
if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In
this event, have the camera position and
setting checked at a qualified specialist
workshop. Mercedes-Ben zrecommends
that you use a Mercedes-BenzS ervice
Centre for this purpose. 200
