2016 MERCEDES-BENZ G-CLASS SUV air condition

Overview of the climat
econtrol sys-
tem General notes
Observe the settings recommended on the fol-
lowing pages. Otherwise, the windows could
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R activate the "Cooling with dehumidification"
function
R activate the "Windscreen demisting" function
briefly, if required
Climate control regu lates the temperature and
the humidity in the vehicle interior and filters
undesirables ubstances out of the air. The "Cooling with air dehumidification" function
is available only when the engin eisrunning.
Optimum operation is only achieved when the
side windows and the sliding sunroof are closed.
Climate comfor tmay be adversely affected if the
sliding sunroof is open for along period of time.
Set the temperature manually if the sliding sun-
roof is open.
The "Residual heat" function can be switched on or off only when the ignition is switched off
(Y page 89).
The integrated filter can filter out most particles of dust and completely filters out pollen. Aclog-
ged filter reduces the amount of air supplied to
the vehicle interior. Dependin gonthe operating
conditions and environmental influences, the
interval for replacing the filter may be shorter
than specified. Control panel for THERMATIC automatic climate control (dual-zone)

WARNING
If you select the LOW RANGE off-road gearon as lippery road surface, the wheels coul dlose
traction:
R if you release the accelerator peda lwhen
the vehicl eisinmotion
R if Off-road ABS intervenes when braking
If the wheels lose traction, it willnol onger be
possible to steer the vehicle. This increases
the risk of skidding and having an accident.
Never select the LOW RANGE off-road gear
when driving on slippery road surfaces.
Information on the parking brake (Y page114).
Downhill gradients Shift to
alower gearing oodt ime on long and
stee pdownhil lgradients.
Take particula rnote of this when driving alad en
vehicl eand when towing atrailer.
Thi sw illu se the braking effect of the engine, so
less braking will be required to maintai nthe
vehicl espeed. Thi srelieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Heav yand light loads G
WARNING
The braking system can overheat if you leave you rfoot on the brake peda lwhile driving.
This increases the braking distance and could
even caus ethe braking system to fail .There is
ar isk of an accident.
Never use the brake peda lasafootrest. Do
not simultaneously depress both the brake
peda land the accelerator peda lwhile driving.
! Depressing the brake peda
lconstantly
results in excessive and premature wearto
the brake pads.
If heavy demands are made on the brakes ,do
not park the vehicl eimmediately. Drive on for a
short while. This allows the airflow to cool the
brakes more quickly.
If the brakes have been used only moderately,
you should occasionall ytest their effectiveness.
To do this, brake more firmly from ahigher speed while paying attention to the traffic con-
ditions .This improves the grip of the brakes.
Wet road surfaces If driving in heavy rain for
aprolonge dperiod of
time withou tbraking, there may be adelayed
reaction from the brakes when braking for the
first time. This may also occur after the vehicle
has been washed.
You have to depres sthe brake pedalm ore
firmly .Maintai nagreater distance from the
vehicle in front.
After driving on awet road or having the vehicle
washed, brake firmly whilep aying attention to
the traffic conditions. This willw arm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads If you drive on salt-treated roads,
alayer of salt
may form on the brake discs and pads.T his can
increase the braking distance considerably.
R In order to prevent any salt build-up,a pplythe
brakes occasionally whilep aying attention to
the traffic conditions.
R Carefullyd epressthe brake pedalatt he end
of the journey and when starting the next
journey.
R Maintai namuch greater distance to the vehi-
cle in front.
New brake discs and brake pads/
linings Brake pads/linings and discs that either are new
or have been replaced achieve optimum braking
effect only after several hundred kilometres of
driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal.
For safety reasons, Mercedes-Benz recom-
mends only fittingt he following brake discs and
brake pads/linings:
R brake discs that hav ebeena pproved by
Mercedes-Benz
R brake pads/linings that hav ebeena pproved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake discs or brake pads/linings can
compromise the safety of your vehicle. 116

on the engine
! Vehicles with
adiesel engine: your vehi-
cle's exhaust gas turbocharger may get very
hot under heavy engine load, e.g. during:
R trailer towing
R longer motorway journeys at high speed
R longer journeys through mountainous ter-
rain
X Let the engine run for approximately another
two minutes while the vehicle is stationary
before switching off the engine.
This way, the exhaust gas turbocharger can
cool down more effectively. Winte

WARNING
If you shift dow nonaslippery road surface in
an attempt to increas ethe engine's braking
effect, the drive wheels coul dlose their grip.
This increases the risk of skidding and having
an accident.

WARNING
If you driv eonas teep incline at an angle or
turn on asteep incline, the vehicl ecoulds lip
sideways, tip and overturn. There is arisk of
an accident.
When driving on an incline, drive into the line of fall (upwards or downward sinastraight
line) and do not turn. G
WARNING
Flammable materia lsuch as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is arisk
of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
! There is
arisk of damage to the vehicl eif:
R the vehicl ebecome sstuck, e.g. on ahigh
kerb or an unpaved road
R you drive too quickly over an obstacle, e.g.
ak erb, slowing thresholds or apothol ein
the road
R ah eavy object strikes the underbody or
parts of the chassis
In situations like this, the body ,underbody,
chassi sparts, wheels or tyres coul dbedam-
agedw ithout the damage being visible. Com-
ponents damaged in this way can unexpect-
edlyf ail or, in the case of an accident, no lon-
ger withstand the strain they are designed to withstand.
If the underbody panelling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody panelling. If these materials
come into contact with hot parts of the
exhaust system, they can catch fire.
In such situations, have the vehicl echecked
and repaired immediatel yataqualified spe-
cialist workshop. If, on continuing yourj our-
ney, you notice that driving safety is impaired, stop the vehicle immediately
,paying atten-
tion to road and traffic conditions. In such
cases, consult aqualified specialist work-
shop.
! If there are steep gradients while driving off-
road, asufficient filling level in the AdBlue ®
tank must be ensured. Make sure for this rea- son that there is aminimum fill level of ten
litres before driving off-road.
When driving off-road, substances such as sand,
mud and water or water mixed with oil may get
into the brakes. This may lead to areduction in
braking performance or total brake failure as a
result of increased wear. The braking charac-
teristics will vary depending on the substances
that get into the brakes. Cleant he brakes after
driving off-road. If you notice grinding noises or ar eduction in braking performance, have the
brake system checked at aqualified specialist
workshop immediately.A dapt your driving style
to the altered braking characteristics.
Driving off-road increases the possibility of dam- age to the vehicle, which may cause assemblies
or systems to fail. Adapt your driving style to the
conditions of the terrain. Drive carefully.H ave
vehicle damage rectified immediately at aquali-
fied specialist workshop.
Do not shift into transmission position Nwhen
driving off-road. You could lose control of the
vehicle if you attempt to brake the vehicle using
the service brake. If the gradient is too steep for your vehicle, back up in reverse gear.

To avoid hazardous situations:
R make sure to check the noseweight before
each journey
R the noseweight should be as close as possible
to the maximum noseweight
R do not exceed the maximum permissible
noseweight
R the noseweight must not be lower than the
minimum permissible noseweight
Make sure that the following values are not
exceeded:
R the permissible noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
When reversin gthe towing vehicle, make sure
there is nobody between the trailer and the vehi- cle.
The applicable permissible values, which must
not be exceeded, can be found:
R in your vehicle documents
R on the type plates for the trailer
R on the vehicle identification plate
If the values differ, the lowest value applies.
You will find the values approved by the manu-
facturer on the identification plates and for the
towing vehicle under "Technical data"
(Y page 256).
When reversin gthe towing vehicle, make sure
there is nobody between the trailer and the vehi- cle.
Couple and uncouple the trailer carefully. If youdo not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
When towing atrailer, your vehicle's handling
characteristics will be different from when driv-
ing without atrailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
R is affected more by stron gcrosswinds
R demands more sensitiv esteering
R has alarger turnin gcircle This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain asafe distance. Drive carefully.
When towing atrailer, alway sadjust your speed
to the current road and weather conditions. Do
not exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on to
wingatrailer
General notes When towing
atrailer, set the tyre pressure on
the rear axle of the towing vehicle for amaxi-
mum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 109).
The height of the ball coupling changes with the load of the vehicle. If necessary, use atrailer
with aheight-adjustable drawbar.
You will find permissible trailer loads under
"Technical data" (Y page 256).
Driving tips X
Observe the information on ESP ®
trailer sta-
bilisation (Y page 55).
X On long and steep downhill gradients, select
shift range 1,2or 3(Y page 105) in good time.
X If necessary, shift the transfer case to LOW
RANGE (Ypage 124).
This will use the braking effect of the engine, so less braking will be required to maintain
the vehicle 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 continu-
ously.
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginnin gthe journey, check the
trailer's documents to see what the maximum
permitted speed is. Observe the maximum per-
missible speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissibler ear axle load is increased
when towing atrailer. See the "Technical data"
section to find out whether this applies to your
vehicle (Y page 256). In the event of increased
rear axle load, the car/trailer combination may
not exceed amaximum speed of 100 km/h for
reasons concerning the operating permit. This 128
