Shifting gears !
Mercedes-AMG vehicles:
the automatic
transmission does not shift up automatically
even when the engine limiting speed for the
current gear is reached. When the engine lim- iting speed is reached, the fuel supply is cut to
prevent the engine from overrevving. Always
make sure that the engine speed does not
reach the red area of the rev counter. There is
otherwise a risk of engine damage. X
To shift up: pull steering wheel gearshift pad-
dle ;.
The automatic transmission shifts up to the
next gear.
All vehicles (except Mercedes-AMG vehi-
cles): if the maximum engine speed in the
currently engaged gear is reached and you
continue to accelerate, the automatic trans-
mission automatically shifts up in order to
prevent engine damage.
X To shift down: pull steering wheel gearshift
paddle :.
The automatic transmission shifts down to
the next gear.
Automatic downshifting occurs when coast-
ing.
If the engine were to exceed the maximum
engine speed when shifting down, the auto- matic transmission protects against engine
damage by not shifting down.
Gearshift recommendation The gearshift recommendation assists you in
adopting a fuel-efficient driving style. The rec-
ommended gear is shown on the multifunction
display.

Upshifting (Mercedes-AMG vehicles) !
In manual mode, the automatic transmis-
sion does not shift up automatically 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. Always
make sure that the engine speed does not
reach the red area of the rev counter. There is
otherwise a risk of engine damage. Before the engine speed reaches the red area,
an upshift indicator will be shown on the multi-
function display.

WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving.
Drive sensibly – save fuel Observe the following tips to save fuel:
R The tyres should always be inflated to the rec-
ommended tyre pressure.
R Remove unnecessary loads.
R Remove roof racks when they are not needed.
R Warm up the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Have all maintenance work carried out as
indicated by the service intervals in the Ser-
vice Booklet or by the service interval display.
Fuel consumption also increases when driving in cold weather, in stop-start traffic, on short jour-
neys and in hilly terrain. ECO display

Driving on wet roads
Aquaplaning If water has accumulated to a certain depth on
the road surface, there is a danger of aquaplan- ing occurring, even if:
R you are driving at low speeds
R the tyres have adequate tread depth
For this reason, drive in the following manner in the event of heavy rain or in conditions in which
aquaplaning can occur:
R lower your speed
R avoid tyre ruts
R avoid sudden steering movements
R brake carefully
Driving on flooded roads !
Bear in mind that vehicles travelling in front
or in the opposite direction create waves. This may cause the maximum permissible water
depth to be exceeded.
These notes must be observed under all cir-
cumstances. You could otherwise damage
the engine, the electronics or the transmis-
sion.
If you must drive on stretches of road on which
water has collected, please bear in mind that:
R in the case of standing water, the water level
must be no higher than the lower edge of the
vehicle body
R you should drive no faster than walking pace Winter driving

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. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden acceleration,
steering and braking manoeuvres. Do not use
cruise control or Distance Pilot DISTRONIC.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission: shift
to neutral.
X Vehicles with automatic transmission:
shift the transmission to position N.
X Try to bring the vehicle under control by using
corrective steering.
The outside temperature indicator is not
designed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in wooded areas or on bridges.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.

Driving tipsDriving and pa
rking
Observe the following notes:
R Stop the vehicle before driving off-road. If
necessary, activate the off-road program
(Y page 151).
R To avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
R Make sure that items of luggage and loads are
stowed safely and are well secured
(Y page 293).
R Always keep the engine running and in gear
when driving on a downhill gradient. Activate
DSR (Y page 190).
R Drive slowly and evenly, if necessary at walk-
ing 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 rea-
sons, get out of the vehicle first and survey
the off-road route.
R Check the depth of water before fording rivers
and streams.
R Watch out for obstacles.
R Take care when turning on an uphill or down-
hill slope or when driving across a slope. The
vehicle could otherwise tip over.
R Always keep the side windows and the pano-
rama sliding sunroof closed during the jour-
ney.
R Do not deviate from marked routes.
R 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 sur- faces.
Checklist before off-road driving X
Engine oil level: check the engine oil and top
it up if necessary.
When driving on steep gradients, the oil level must be sufficiently high to ensure a correct
oil supply 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 Wheels: dented or bent wheels can lead to a
loss of tyre pressure and damage to the tyre
bead. Before driving off-road, check the
wheels and replace them if necessary.
Checklist after off-road driving !
If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at a qualified specialist work-
shop.
X Deactivate the off-road program
(Y page 151).
X Deactivate DSR (Y page 190).
X Clean the headlamps and rear lights and
check for damage.
X Clean the front and rear licence plates.
X Clean the wheels and tyres with a water jet
and remove any foreign objects.
X Clean the wheels, wheel arches and the vehi-
cle underside with a water jet; check for any
foreign objects and damage.
X Check whether twigs or other parts of plants
have become trapped. These increase the risk
of fire and can damage fuel pipes, brake
hoses or the air bellows of the axle joints and propeller shafts.
X After the trip, examine without fail the entire
undercarriage, wheels, tyres, brakes, body-
work structure, steering, chassis and exhaust
system for damage.
X After driving in sand, mud, gravel, water or
similar dirty conditions, have the following
checked and cleaned:
R brake discs
R wheels
R brake pads
R axle joints
X If you detect strong vibrations after driving
off-road, check for foreign objects in the
wheels and drive train and remove them if
necessary. Foreign objects can disturb the
balance and cause vibrations.
Driving over poor road surfaces places greater
demands on your vehicle than driving on normal roads. After driving off-road, check the vehicle.
This allows you to detect damage promptly and
reduce the risk of an accident to yourself and
other road users. 174
Driving tipsDriving and parking
Driving on sand
Observe the following rules when driving on
sand:
R Activate the off-road program (Y page 151).
R Avoid high engine speeds.
R Use the left-hand steering wheel gearshift
paddle to shift to a lower gear appropriate to
the terrain.
R Drive quickly to overcome the rolling resist-
ance. Otherwise, the vehicle could dig itself
into the sand.
R Drive in the tracks of other vehicles if possi-
ble. Make sure that:
- the tyre ruts are not too deep
- the sand is firm enough
- your vehicle has sufficient ground clear-
ance
Tyre ruts and unpaved roads !
Check that the ruts are not too deep and
that your vehicle has sufficient clearance.
Otherwise, your vehicle could be damaged or bottom out and get stuck.
Observe the following rules when driving along
ruts in off-road terrain or on roads with loose
gravel: R Activate the off-road program (Y page 151).
R Avoid high engine speeds.
R Shift to a lower gear using the left-hand steer-
ing wheel gearshift paddle.
R Drive slowly.
R Where ruts are too deep, drive with the
wheels on one side on the middle section of
turf if possible. Travelling uphill
Approach/departure angle G
WARNING
If you drive on 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 on an incline, drive into the line of fall (upwards or downwards in a straight
line) and do not turn. R
Observe the warnings for off-road driving
(Y page 173).
R Follow the line of fall when driving on slopes
and steep inclines.
R Before driving on extreme uphill and extreme
downhill gradients, select the off-road pro-
gram (Y page 151).
R Drive slowly.
R Accelerate gently and make sure that the
wheels are gripping.
R Avoid high engine speeds, except when driv-
ing on sandy and muddy routes with high driv-
ing resistance.
R Use the left-hand steering wheel gearshift
paddle to shift to a lower gear appropriate to
the gradient.
R Use the left-hand gearshift paddle to shift to a
lower gear on long and steep downhill gradi-
ents.
Hill start assist will aid you when pulling away on
a hill. Further information on hill start assist
(Y page 147).
Do not shift into transmission position iwhen
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.
Always observe the approach/departure angle
values (Y page 359).
Maximum gradient-climbing capability Always observe the maximum gradient climbing
ability values (Y page 359).
Hilltops When driving up an uphill gradient, slightly
reduce pressure on the accelerator immediately
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 the vehicle from travelling too quickly down
the other side Driving tips
