2014 MERCEDES-BENZ G-CLASS SUV light

If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may
be the case if the vehicles are driving on the
inner side of their lane.
Due to the nature of the system:
R warnings may be issued in error when
driving close to crash barriers or similar
solid lane borders.
R the warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
The two sensors for Blind Spot Assist are
integrated into the sides of the rear bumper.
Make sure that the bumper is free from dirt,
ice or slush around the sensors. The rear
sensors must not be covered, for example by
bicycle racks or overhanging loads. Following
a severe impact or in the event of damage to
the bumpers, have the function of the radar
sensors checked at a qualified specialist
workshop. Blind Spot Assist may otherwise
not work properly.
Indicator and warning display 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 6.8 mph
(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
carefully, and maintain a safe lateral distance. :
Yellow indicator lamp/red warning lamp
When Active Blind Spot Assist is activated,
indicator lamp :in the exterior mirrors lights
up yellow at speeds of up to
20 mph(30 km/h). At speeds above 20 mph
(30 km/h) the indicator lamp goes out and
Blind Spot Assist is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
20 mph (30 km/h), warning lamp :on the
corresponding side lights up red. This warning
is always emitted when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 7 mph (12 km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Blind Spot
Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. 122

General notes The HOLD function can assist the driver in the
following situations:
R
when pulling away, especially on steep
slopes
R when maneuvering on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
i Do not use the HOLD function when
driving off-road, on steep uphill or downhill
gradients or on slippery or loose surfaces.
The HOLD function cannot hold the vehicle
on such surfaces.
Activation conditions You can activate the HOLD function if:
R
the vehicle is stationary.
R the engine is running or it has been
switched off by the ECO start/stop
function (AMG vehicles).
R the engine is running.
R the driver's door is closed or your seat belt
is fastened.
R the transmission is in position D,Ror N.
R DISTRONIC PLUS is deactivated.
Activating the HOLD function The vehicle's brakes are applied when the
HOLD function is activated. For this reason,
deactivate the HOLD function while in the car
wash or while towing. Driving systems

Important safety notes The rear view camera is only an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering and
parking. When maneuvering or parking, make
sure that there are no persons, animals or
objects in the area in which you are
maneuvering.
Under the following circumstances, the rear
view 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,

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

Shifting the transfer case
Important safety notes
G
WARNING
When the transfer case is in the neutral
position, power transmission to the driven
wheels is interrupted. As a result, the vehicle
could roll away. There is a risk of an accident.
Secure the vehicle with the parking brake, and
on uphill or downhill gradients, also secure it
with a device such as a wheel chock.
Always wait for the gear change process from
HIGH RANGE toLOW RANGE and from
LOW RANGE toHIGH RANGE to complete.
Do not turn off the engine while changing gear
and do not shift the automatic transmission
to another gear.

Off-road driving systemsDriving and parking

Your vehicle is equipped with a differential
lock each for:
R the transfer case: this controls the balance
between the front and rear axles.
R the rear axle: this controls the balance
between the wheels on the rear axle.
R the front axle: this controls the balance
between the wheels on the front axle.
Information on differential and
differential locks When the vehicle drives around a curve, the
wheels on the outside of the curve must cover
a greater distance. Therefore, the wheels turn
more rapidly than on the inside. The
differential, a transmission in the drive train,
compensates for these different rotational
speeds, making cornering possible.
The disadvantage of a differential is that more
power is transferred to the wheels that have
the least grip. An example: a wheel of a driven
axle is on a snow-covered surface and
therefore does not have any traction. The
differential causes this wheel to be subjected
to the strongest driving force, as the flow of
force takes the path of least resistance. The
opposite wheel on this axle, however, which
stands on firm ground and could therefore
allow propulsion, receives no driving power.
4ETS compensates for this disadvantage.
4ETS provides good steerability by
automatically braking the spinning wheel.
4ETS provides the wheel on the firm surface
with more drive force, which in turn provides
propulsion.
ESP® and 4ETS are traction systems that are
ideal for road driving and suitable for light off-
road driving. The LOW RANGEoff-road gear
also improves off-road capability.
Moreover, the more difficult conditions in off-
road driving require further measures such as
locking one or several differentials. Your
vehicle is equipped with three differential
locks: R
a central differential lock for the transfer
case,
R a differential lock for the front axle and
R a differential lock for the rear axle.
Each differential lock can be engaged with the
respective switch on the center console. If
the transfer case differential is disabled, the
front and rear wheels turn at the same speed.
If the differential for the rear axle is locked,
both rear wheels turn at the same speed,
regardless of their individual torques. Please
note that activating the differential locks
severely restricts the vehicle's steerability.
Please note that the functions of the
differential are absolutely necessary for
driving on paved roads. The differential locks
must never be engaged when driving on
paved roads. Otherwise, the vehicle may not
be steerable and you could lose control of the
vehicle. The differential locks must therefore
only be engaged when driving off-road. You
may only engage the differential locks if the
functions of the 4ETS and ESP ®
driving
systems and the LOW RANGEoff-road gear
are insufficient.
i The differential locks are only available in
the LOW RANGE off-road gear.
Engaging the differential locks Important safety notes
G
WARNING
When differential locks are engaged on a firm,
high-grip surface, the vehicle's steerability is
greatly impaired. In particular, engaging the
differential locks when cornering could lead
to you losing control of the vehicle. There is a
risk of an accident.
Disengage the differential locks immediately
on firm surfaces with good grip. G
WARNING
When the differential locks are engaged, ABS,
4ETS, ESP ®
and BAS are deactivated. As a
result, the wheels could lock when braking 132
Off-road driving systemsDriving and parking

and the braking distance is increased. There
is a risk of an accident.
Disengage the differential locks immediately
on firm surfaces with good grip.
! Only engage the differential locks when:
R you are driving at walking pace.
R the driven wheels are not spinning.
R you are not driving on a firm road surface.
