It is only possible to move the DIRECT
SELECT lever to the desired position from
position Pif you depress the brake pedal.
Only then is the parking lock released.
i The vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors from the inside at
any time.
You can also deactivate the automatic lock-
ing feature (Y page 107).
X Depress the brake pedal and keep it
depressed.
X Shift the transmission to position Dor R.
X Release the parking brake (Y page 91).
X Release the brake pedal.
X Carefully depress the accelerator pedal.
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 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 time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll. G
Risk of accident
Never leave the vehicle when it is held by hill
start assist. After approximately one second,
hill start assist will no longer brake your vehi-
cle and it could roll away.
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 vehicle is secured with the parking
brake.
R ESP ®
is malfunctioning. Parking
G
Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle with the key removed.
Never leave children unsupervised in the vehi-
cle. They could release the parking brake. This
could lead to a serious or fatal accident. G
Risk of fire
Make sure that the exhaust system does not
under any circumstances come into contact
with flammable materials such as dry grass or
petrol. The material could otherwise ignite
and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be applied
R the transmission must be in position Pand
the ignition key must be removed
R on steep uphill or downhill gradients, turn
the front wheels towards the kerb 90

G
Risk of accident
At temperatures just above freezing point, the
road could be icy, particularly in wooded areas
or on bridges. The vehicle could start skidding
if you fail to adapt your driving style. You
should therefore always adapt your driving
style and speed to suit the weather condi-
tions.
Changes in the outside temperature are dis-
played after a short delay. On-board computer
Points to remember
The on-board computer is activated as soon
as you turn the key to position 1in the ignition

Risk of accident
Only use the on-board computer when road
and traffic conditions permit. You would oth-
erwise be distracted and unable to concen-
trate properly on driving, and could cause an
accident. Multi-function steering wheel

Only vehicles with auxiliary heating have this
function.
The
Aux.heating departure time function
allows you to select a stored departure time
or change the departure time for which the
vehicle with auxiliary heating is preheated.
The auxiliary heating timer function calcu-
lates the switch-on time according to the out-
side temperature so that the vehicle is pre-
heated by the departure time. When the
departure time is reached, the auxiliary heat-
ing continues to heat for a further five
minutes and then switches off. The auxiliary
heating adopts the temperature settings
selected for Thermatic 2-zone automatic cli-
mate control or Thermotronic luxury multi-
zone automatic climate control*.
You can switch off the auxiliary heating by
using the remote control or the auxiliary heat-
ing button on the centre console. G
Risk of poisoning
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
Risk of fire
When the auxiliary heating is in operation,
parts of the vehicle can become very hot.
Make sure that the exhaust system does
not under any circumstances come into con-
tact with highly flammable materials such as
dry grass or fuels. The highly flammable mate-
rial could otherwise ignite and set the vehicle
alight. Select your parking space accordingly.
Operating the auxiliary heating is therefore
prohibited at filling stations or when your vehi-
cle is being refuelled. Always switch off the
auxiliary heating at filling stations. On-board computer

Overview of off-road driving systems
The systems which are relevant for off-road
driving are explained on the following pages:
R 4MATIC (permanent four-wheel drive), for
optimum traction
R DSR (Downhill Speed Regulation), which
assists you when driving downhill
R LOW RANGE off-road gear for better trac-
tion off-road
R Differential locks for increased traction off-
road
You will find further information about driving
off-road in the "Operation" section
(Y page 188). 4MATIC (permanent four-wheel drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
and
4ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to insuffi-
cient grip. G
Risk of accident
4MATIC cannot reduce the risk of an accident
if you drive too fast.
If a drive wheel spins due to insufficient grip:
R only depress the accelerator pedal as far as
necessary when pulling away.
R accelerate less when driving.
R adapt your driving style to suit road and
traffic conditions.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres), with snow
chains if necessary.
! When testing the parking brake, operate
the vehicle only briefly (for a maximum of
ten seconds) on a brake test dynamometer.
When doing this, turn the key to position 112

Permanent Speedtronic is deactivated.
R A limit speed between 240 km/hand
160 km/h in increments of 10 km/h. ADS (Adaptive Damping System)
ADS adapts the damping characteristics to
the current operating and driving situation.
How this is adjusted depends on:
R your driving style
R the road surface conditions
R the ADS setting
R the vehicle level setting
Your selection remains stored even if you
remove the key from the ignition lock. You can choose between the following ADS
settings:
R
AUTO for normal driving situations; indica-
tor lamps ;and =are off.
R SPORT for sporty driving; indicator
lamp ;is on. In comparison to AUTOor
COMF, the vehicle is 15 mm lower.
R COMF for a more comfortable ride; indica-
tor lamp =is on.
X Start the engine.
X Press button :repeatedly until the
desired setting is selected. Level control
The level control adapts the vehicle level
automatically to the current operating and
driving situation. This results in reduced fuel
consumption and improved handling.
When you are driving in ADS COMForAUTO
ADS (Ypage 129), the vehicle is lowered to
the high-speed level as the speed increases.
As the vehicle decelerates, the vehicle is
raised back up to highway level.
In ADS SPORT (Ypage 129), the vehicle skips
highway level and is lowered directly to high-
speed level.
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle
to adjust to the new level as quickly as pos-
sible.
The vehicle level may change visibly when you
park the vehicle and the outside temperature
changes. When the temperature drops, the
vehicle level is lower; with an increase in tem-
perature, the vehicle level rises.
When you unlock the vehicle or open a door,
the vehicle begins to balance the load dis-
crepancies while still parked. However, for
significant level changes, e.g. after the vehi-
cle has been stationary for a long period, the
engine must be on. For safety reasons, the
vehicle is only lowered when the doors are
closed. Lowering is interrupted if a door is
opened and continues when the door has
been closed. G
Risk of injury
Make sure that nobody is in the vicinity of the
wheel arch or the underbody when you begin
a level change. You could otherwise trap your-
self or others. G
Risk of accident
Always select as low a vehicle level as possi-
ble. If the vehicle level is high, the vehicle
centre of gravity shifts upwards. This increa-
ses the risk of the vehicle tipping over. Driving systems
