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.

The ECO display consists of three sections, with
an inner and outer area. The sections corre-
spond to the following three categories: :
Acceleration
(evaluation of all accel-
eration processes):
R the outer area fills up and the inner
area lights up green: moderate
acceleration, especially at higher
speeds
R the outer area empties and the
inner area is grey: sporty acceler-
ation ;
Coasting
(evaluation of all decelera-
tion processes):
R the outer area fills up and the inner
area lights up green: anticipatory
driving, keeping your distance and
early release of the accelerator.
The vehicle can coast without use
of the brakes.
R the outer area empties and the
inner area is grey: frequent heavy
braking =
Constant
(continuous evaluation
over the entire journey):
R the outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and deceleration
R the outer area empties and the
inner area is grey: fluctuations in
speed The three inner areas display the current driving
style and light up green as a result of a particu-
larly economical driving style. Depending on the driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as a result of eco-
nomical driving. A higher level indicates a more
economical driving style. If the three outer areas
are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved range
displayed under Bonus fr. start
Bonus fr. start does not
indicate a fixed consumption reduction. In addition to driving style, the actual consump-
tion is affected by other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factors are not included in the ECO dis-
play.
An economical driving style involves driving at a moderate engine speed.
To achieve a higher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendation
R drive the vehicle in the Comfortdrive pro-
gram.
On long journeys at a constant speed, e.g. on the
motorway, only the outer area for "Constant"
will change.
The ECO display summarises the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of a journey. During a prolonged driving time, these changes are
smaller. For more marked changes, perform a
manual reset (Y page 245).

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 Do not depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by constantly applying light
pressure to the pedal. This results in excessive
and premature wear to the brake pads. Driving tips
173Driving and parking Z

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.
! Take care not to damage the sealing strip
and the moulding on the side of the rear win- dow when scraping ice off the rear window.
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 Shift the transmission to position N.
X Try to bring the vehicle under control by using
corrective steering.
When driving in snow with or without snow
chains, select driving program Slippery
(Y page 155).
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 conditions when tem-
peratures are around freezing point.

section (Y page 369). Off-road driving
Important safety notes 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. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk 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. G
WARNING
If the vehicle level is high, the vehicle centre of gravity is raised. This could cause the vehicleto tip over more easily on uphill or downhill
gradients. There is a risk of an accident.
Select the lowest possible vehicle level.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
kerb or an unpaved road
R you drive too fast over an obstacle, e.g. a
kerb, a speed bump or a pothole in the road
R a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tyres could be damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed
to.
If the underbody panelling is damaged, com-
bustible materials such as leaves, grass or 176

i Information about retrofitting special all-ter-
rain tyres is available from any qualified spe-
cialist workshop.
i 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 AdBlue ®
tank (BlueTEC vehicles): check the
level and top up if necessary (Y page 166).
X Tyre-change tool kit: check that the jack is
working and make sure that the wheel
wrench, a robust tow cable and a folding
spade are 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.
Driving over rough terrain 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.
X If the Off-road orOff-road Plus drive pro-
gram is selected: select the Individual,Sport,
Comfort orSlippery drive program
(Y page 155).
X Deactivate the LOW RANGE offroad gear
(Y page 230).
X Deactivate DSR (Y page 227).
X Lower the vehicle level again to a level suita-
ble to the road conditions, e.g. to the normal
level.
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 rubber 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 for extended periods across
sand, mud, gravel, water or in similarly dirty
conditions, have the brake discs, wheels,
brake pads/linings and axle joints checked
and cleaned.
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 on sand Observe the following rules when driving on
sand:
R Select the Offroaddrive program (vehicles
without Off-Road Engineering package)
(Y page 228).
R Select the Offroaddrive program (vehicles
