problems shifting gear. The transmission is losing oil.
X Have the transmission checked at a qualified specialist workshop
immediately. The acceleration charac-
teristics are deteriorat-

This section only applies to vehicles with all-
wheel drive (4MATIC). The front and rear axles
are constantly driven.
! Performance tests may only be carried out
on a two-axle roller dynamometer. Otherwise,
the braking system or the transfer case could be damaged. Contact a qualified specialist
workshop for more information on perform-
ance tests.
! Since ESP ®

tion must be switched off (the key or Start/
Stop button must be in position 0or 1) if:
R the electric parking brake is being tested
using a brake dynamometer.
R the vehicle is being towed with only one
axle raised (not permitted for vehicles with

WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rial can come into contact with hot vehicle
components. In particular, do not park on dry grassland or harvested grain fields. G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle.
! Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its driv-
etrain could be damaged. Parking
159Driving and parking Z

To ensure that the vehicle is secured against
rolling away unintentionally:
R the electric parking brake must be applied
R on vehicles with manual transmission, engage
first gear or reverse gear
R on vehicles with automatic transmission, the
transmission must be in position Pand the
key must be removed from the ignition lock
R the front wheels must be turned towards the
kerb on steep uphill or downhill gradients
R the empty vehicle must be secured at the
front axle with a wheel chock or similar
object, for example, on uphill or downhill gra-
dients
R on uphill or downhill gradients the laden vehi-
cle must also be secured at the rear axle, for

The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or the system is malfunc-
tioning, it may not be possible to apply the
released parking brake. X If this is the case, park the vehicle only on
level ground and secure it to prevent it from
rolling away.
X Vehicles with automatic transmission:
shift the automatic transmission to position
P.
X Vehicles with manual transmission:
engage first gear.
It may not be possible to release an applied
parking brake if the on-board voltage is low or if
there is a malfunction in the system. Contact a
qualified specialist workshop.

Important safety notes G
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:
X The tyres should always be inflated to the rec-
ommended tyre pressure.
X Remove unnecessary loads.
X Remove roof racks when they are not needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the Ser-
vice Booklet or by the service interval display.
