ing feature (Y page 223).
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill starta ssist G
WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and depress it before the vehicle begins to
roll.
X Take your foot off the brake pedal.
i Once you have taken your foot off the
brake pedal, the vehicle is held for around
one second.
X Pull away.
Hill start assist will not function if:
R you are pulling away on a level road or a
downhill gradient.
R the transmission is in position N.
R the parking brake is applied.
R ESP ®
is malfunctioning. ECO start/stop function (AMG vehi-
cles)

WARNING
If the engine is switched off automatically and
you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving.
There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.
General notes The ECO start/stop function is only available
for the G 63 AMG.

damage by not shifting down.
i If the maximu mengine speed for the shift
range is reached and you continue to accel-
erate, the automatic transmission shifts up
in order to prevent the engine from over-
revving, eve nifthe shift range is restricted.
Extending the shift range X
Pull the right-hand steering wheel gearshift
paddle (Y page 153).
The automatic transmission shifts up one
gear and restricts the shift range to the rel-
evant gear.

gearshift paddle (Y page 153) untilDis
shown again in the multifunction display.
The automatic transmission shifts from the
current shift range directly to D.
Selecting the ideal shift range X
Pull the left-hand steering wheel gearshift
paddle (Y page 153) and hold it in position.
The automatic transmission shifts to the
gear which allows optimum acceleration
and deceleration. To do this, the automatic
transmission shifts down one or more
gears.
i The automatic transmission cannot shift
down beyond second gear. To shift to first

matically even when the engine limiting
speed for the current gear is reached.
When the engine limiting speed is reached,
the fuel supply is cut to prevent the engine
from overrevving. You must make sure that
the engine speed does not reach the red
area of the rev counter. Otherwise, there is
a risk of engine damage.

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

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.

Off-road driving
Important safety notes G
WARNING
If you drive up a steep incline at an angle or
turn on a steep incline, the vehicle could slip
sideways, tip and overturn. There is a risk of
an accident.
When driving up an incline, drive into the line
of fall (upwards or downwards in a straight
line) and do not turn.
! G350 BlueTEC:
The level in the AdBlue ®
tank needs to be
sufficiently high to compensate for driving
at extreme angles when driving off-road.
Before driving off-road, make sure that the
tank contains a minimum of ten litres.
When driving off-road, sand, mud and water,
possibly mixed with oil, for example, could get
into the brakes. This may lead to a reduction
in braking performance or total brake failure
as a result of increased wear. The braking
characteristics will vary, depending on the
substances that get int othe brakes. Cleant he
brakes after driving off-road. If you notice
grinding noises or a reduction in braking per-
formance, have the brake system checked at
a qualified specialist workshop immediately.
Adapt your driving style to the altered braking
characteristics.
Driving off-road increases the possibility of
damage to the vehicle, which may cause
assemblies or systems to fail. Adapt your
driving style to the conditions of the terrain.
Drive carefully. Have vehicle damage rectified
immediately at a qualified specialist work-
shop. Observe the following when on hilly roads:
R
Do not shift the transmission to position
N.
R If the gradient is too steep for your vehicle,
back up in reverse gear.
R Do not continuously depress the brake
pedal, as doing so could cause you to lose
control.
General notes H
Environmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.
Read this section before driving your vehicle
off-road. Practise by travelling over more gen-
tle off-road terrain first.
The following driving systems are specially
adapted to off-road driving:
R 4ETS (Y page 62)
R Transfer case (Y page 201)
R Differential locks (Y page 204)
Observe the following notes:
R stop your vehicle and, if necessary, shift the
transfer case to LOW
RANGE(Y page 202) before driving off-
road.
R AMG vehicles: to shift the transfer case to
LOW RANGE, deactivate the ECO start/
stop function (Y page 146).
R engage the differential locks, if necessary
(Y page 204)
i ABS,4 ETS, ESP ®
and BAS are deactivated
while the differential locks are engaged.
This allows the front wheels to lock briefly,
so tha tthey can dig into a loose surface.

large obstacles. Any damage to the vehicle
always increases the risk of an accident.
! Drive with particular care when driving
over an obstacle while driving up or down
a steep slope.
The vehicle could otherwise tilt and slide
sideways or tip over. Observe the following rules when driving over
tree stumps, large stones and other obsta-
cles:
R
Observe the safety notes (Y page 169)and
the general notes (Y page 169) on off-road
driving.
R Shift the transfer case to LOW

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
173Driving and parking Z

Do not use cruise control:
R
in traffi cconditions that do not allow you
to drive at a constant speed, e.g. heavy
traffic, on winding roads or off-road
R on slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
General notes Cruise control maintains a constant road
speed for you. On long and steep downhill
gradients, especially if the vehicle is laden or
towing a trailer, you must select shift range
1,
2or 3in good time. By doing so, you will
make use of the braking effect of the engine.
This relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h.
