Changing gear
The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D.Gearshifting is deter-
mined by:
R a shift range restriction, if selected
R the position of the transfer case (HIGH
RANGE orLOW RANGE)
R the position of the accelerator pedal
R the road speed Driving tips
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear:
R
little throttle: early upshifts
R more throttle: late upshifts
Kickdown Use kickdown for maximum acceleration.
X
Depress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.
X Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Towing atrailer X

Automatic transmissionDriving and parking

drive short distances, you should take a 20
minute trip on a motorway or rural road at
least every 500km. Brakes
Important safety notes G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must select shift range
1,2or 3
(Y page 153) in good time.
i This also applies if you have activated
cruise control or SPEEDTRONIC.
This will use the braking effec tofthe engine,
so less braking will be required to prevent the
vehicle from gaining 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.
Heavy and light loads G
WARNING
The braking system can overheat if you leave
your foot on the brake pedal while driving.
This increases the braking distance and could
even cause the braking system to fail. There
is a risk of an accident.
Never use the brake pedal as a footrest.Do
not simultaneously depress both the brake
pedal and the accelerato rpedal while driving. If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the air-
flow to cool the brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet road surfaces
If driving in heavy rain for a prolonged period
of time without braking, there may be a
delayed reaction from the brakes when brak-
ing for the first time. This may also occur after
the vehicle has been washed.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehi-
cle washed, brake firmly while paying atten-
tion to the traffic conditions .This will warm
up the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salt-
treated roads If you drive on salt-treated roads, a layer of
salt may form on the brake discs and pads.
This can increase the braking distance con-
siderably.
R
Apply the brakes occasionally in order to
prevent any salt build-up. Ensure that you
do not endanger other road users when
doing so.
R Carefully depress the brake pedal at the
end of the journey and when starting the
next journey.
R Maintain a much greater distance to the
vehicle in front. Driving tips
165Driving and parking Z

R
Chec kthat items of luggage and loads are
stowed safely and are well secured
(Y page 271).
R To avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
R Always keep the engine running and in gear
when driving on a downhill gradient.
R Always keep the engine running and in gear
when driving on a slope.
R Drive slowly and evenly, if necessary at
walking pace.
R Ensure that the wheels are in contact with
the ground at all times.
R Drive with extreme care on unknown off-
road routes where visibility is poor. For
safety reasons, get out of the vehicle first
and survey the off-road route.
R Check the depth of water before fording
rivers and streams.
R When fording, do not stop and do not
switch off the engine.
R Look out for obstacles such as rocks, holes,
tree stumps and furrows.
R Always keep the doors, the rear door or
tailgate (G-Class Cabriolet), the side win-
dows and the sliding sunroof closed while
the vehicle is in motion.
R Switch off cruise control and variable
SPEEDTRONIC.
R Do not stray from marked routes or paths.
R Adapt your speed to the terrain. The
rougher, steeper or more ruts on the ter-
rain, the slower your speed should be.
R Drive slowly and at a constant speed
through the water. Ensure that a bow wave
does not form as you drive.
R On sand, drive quickly to overcome the roll-
ing resistance. Otherwise, the vehicle could
dig itself into the sand.
R Do not jump with the vehicle as this will
interrupt the vehicle's propulsion. R
Avoid high engine speeds. Drive at appro-
priate engine speeds.
R Always check the vehicle for damage after
off-road driving.
i Information about retrofitting special all-
terrain tyres is available from any qualified
specialist workshop.
i Do 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.
Checklist before driving off-road !
If the engine oil warning lamp lights up
during the journey, stop the vehicle in a
safe place as soon as is possible. Check the
engine oil level. The warning given by the
engine oil warning light must not be
ignored. Continuing your journey when the
symbol is shown may result in engine dam-
age.
X Engine oil level: check the engine oil and
top it up if necessary.
Only then does the engine receive enough
oil when the vehicle is standing on a steep
incline.
X G3 50 BlueTEC: have the AdBlue ®
level
checked at a qualified specialist workshop
(Y page 160).
X Tyre-change tool kit: check that the jack
is working and make sure you have the
wheelbrace, a robust tow cable and a fold-
ing spade in the vehicle.
X Wheels and tyres: check the tyre tread
depth and tyre pressure.
X Check for damage and remove any foreign
objects, e.g. small stones, from the
wheels/tyres.
X Replace any missing valve caps.
X Replace dented or damaged wheels.
X Carry a sound spare wheel. 170
Driving tipsDriving and parking

R
Accelerate gently and make sure that the
wheels are gripping.
R Avoid high engine speeds, except when
driving on sandy and muddy routes with
high driving resistance.
R Whe ndriving downaslope, use the braking
power of the engine. Observe the engine
speed; do not overrev the engine.
R Select a shift range appropriate to the gra-
dient.
R Before tackling steep downhill gradients,
select shift range 1(Ypage 153).
R Always check the brakes after driving off-
road.
Maximum gradient-climbing capability On good road surfaces and with the
LOW
RANGE gear selected, the maximum gradi-
ent-climbing capability is 80%.
i If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS recognises this and brakes the
wheels accordingly. The rear wheel torque
is increased and it is easier to pull away.
Hilltops When driving up an uphill gradient, slightly
reduce pressure on the accelerator immedi-
ately before reaching the brow of the hill.
Make use of the vehicle's own impetus to
travel over the brow.
This style of driving prevents:
R the vehicle from lifting off the ground on the
brow of a hill
R loss of traction
R the vehicle from travelling too quickly down
the other side.
Driving downhill R
Before tackling steep downhill gradients,
select shift range 1(Ypage 153). This way you use the engine's braking
effect to reduce the speed. If this is not
sufficient, brake gently. When doing so,
make sure that the vehicle is facing in the
direction of the line of fall.
R Observe the notes on driving in mountain-
ous terrain (Y page 173).
R Drive slowly.
R Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight. Oth-
erwise, the vehicle could slip sideways, tip
and overturn.
R Check that the brakes are working normally
after a long downhill stretch. Driving systems
Cruise control
Important safety notes G
WARNING
The brake pedal moves when cruise control
brakes the vehicle. Afoot in the area under
the brake pedal could become trapped. The
movement of the pedal, and therefore the
vehicle's ability to brake, may be restricted by
objects in the area under the brake. There is
a risk of an accident and injury.
Do not place your foot under the brake pedal.
Keep the area under the brake pedal free from
obstructions.
If you fail to adapt your driving style, cruise
control can neither reduce the risk of acci-
dent nor override the laws of physics. Cruise
control cannot take account of road, weather
and traffic conditions. Cruise control is only
an aid. You are responsible for the distance
to the vehicle in front, for vehicle speed and
for braking in good time. Adjust your driving
style to the traffic conditions. Only engage
cruise control when the current road, weather
and traffic conditions permit it to be done
safely. Drive carefully and maintain a suitable
distance to the vehicle in front. Driving systems
