2015 MERCEDES-BENZ G-CLASS SUV stop start

The vehicle may roll away. There is a risk of anaccident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parkingbrake.
iBear in mind that the power transmission
between the engine and the transmission is interrupted when the engine is switched
off. For this reason, shift the automatic
transmission to Pwhen the engine is
switched off and the vehicle is at a stand-
still. Apply the parking brake to prevent the vehicle from rolling away.

Overview of transmission positions
!If the engine speed is too high or if the
vehicle is rolling, do not shift the transmis-
sion directly from Dto R, from Rto Dor
directly to P.
Do not open the driver's door while the
vehicle is in motion. At low speeds in trans-
mission position Dor R, park position Pis
otherwise engaged automatically.
The transmission could be damaged.

If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds. Red warning lamp :flashes. If
the turn signal remains on, vehicles detected
are indicated by the flashing of red warninglamp :. There are no further warning tones.

X Make sure that Blind Spot Assist is activa-
ted in the on-board computer(Y page 147).
X Turn the SmartKey to position 2in the igni-
tion lock ( Ypage 103).
Warning lamps :in the exterior mirrors
light up red for approximately 1.5 seconds
and then turn yellow.
HOLD function
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.
iDo not use the HOLD function when driv-
ing off-road, on steep uphill or downhill gra- dients 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 func-
tion (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,R or 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.
X Make sure that the activation conditions
are met.
X Depress the brake pedal.
X Quickly depress the brake pedal furtheruntil ë appears in the multifunction dis-
play.
The HOLD function is activated. You can
release the brake pedal.
iIf depressing the brake pedal the first
time does not activate the HOLD function,
wait briefly and then try again.

is interrupted. As a result, the vehicle could
roll away. There is a risk of an accident.
Secure the vehicle with the parking brake, andon 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 switch off the engine while changing
gear and do not shift the automatic transmis-
sion to another gear.

GWARNING
When the transfer case is in the neutral posi-

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.

stopping and backing up in a traffic-free location.
R Before driving, check:
- Trailer tow hitch
- Safety switch for braked trailers
- Safety chains
- Electrical connections
- Lights
- Wheels
R Adjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
R If the trailer features electronically control-
led brakes, pull away the vehicle/trailer
combination carefully, manually brake
using the brake controller, and check the
brakes for correct function.
R Secure any objects on the trailer to prevent
the cargo from slipping when the vehicle is
in motion.
R If you couple up a trailer, regularly check
the cargo for secure fastening and make
sure that the trailer lamps and (if applica-
ble) the trailer brakes are functioning cor-rectly.
R Bear in mind that the handling will be less
stable when towing a trailer than when driv-
ing without one. Avoid sudden steeringmovements.
R The vehicle/trailer combination is heavier,
accelerates more slowly, has a decreased
gradient climbing capability and a longer
braking distance.
It is more susceptible to side winds and
requires more careful steering.
R If possible, avoid abrupt braking. Depress
the brake pedal moderately at first, so that
the trailer can activate its own brakes. Thenincrease the pressure on the brake pedal.
R If the automatic transmission continues to
shift back and forth between two gears
when driving up or downhill, restrict the
shift range. Select shift range 4, 3, 2,or1.
A lower gear and lower speed reduce the
risk of engine failure. R
When driving downhill, shift to a lower gear
to utilize the engine's braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if
installed, the trailer brakes.
R If the coolant temperature increases dra-
matically while the air-conditioning system
is switched on, switch off the air-condition-
ing system.
Coolant heat can additionally be dissipated
by opening the windows and by setting the
blower fan and the interior temperature tomaximum.
R When overtaking, pay particular attention
to the extended length of your vehicle/
trailer combination.
Due to the length of your vehicle/trailer
combination, you will have to travel an addi-
tional distance beyond the vehicle you are
overtaking before returning to the previous lane.
Decoupling a trailer
!
Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound- ing of the overrun brake.
X Make sure that the automatic transmission
is set to position P.
X Apply the parking brake.
X Start the engine.
X Close all doors, including the rear door.
X Apply the trailer's parking brake.
X Detach the trailer cable and decouple thetrailer.
X Switch off the engine.

Do not drive when your engine is overheated. This can cause some
fluids which may have leaked into the engine compartment to
catch fire.
Steam from the overheated engine can also cause serious burns
which can occur just by opening the hood.
There is a risk of injury. X Pull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions.
X Secure the vehicle against rolling away ( Ypage 110).
X Leave the vehicle and keep a safe distance from the vehicle until
the engine has cooled down.
X Make sure that the air supply to the engine radiator is not
blocked, e.g. by snow, slush or ice.
X Do not start the engine again until the display message goes out
and the coolant temperature is below 248 ‡ (120 †). Other-
wise, the engine could be damaged.
X Pay attention to the coolant temperature display.
X If the temperature increases again, visit a qualified specialist
workshop immediately.
Under normal operating conditions and with the specified coolant
level, the coolant temperature may rise to 248 ‡ (120 †).
The poly-V-belt may have torn.
X Pull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions.
X Check the poly-V-belt.
If the poly-V-belt is torn:
