KEYLESS GO* You can start, lock or unlock the vehicle using
the KEYLESS GO key. To do this, you only
need carry the key with you. When you touch
the surface of the sensors on the vehicle's
door handles, KEYLESS GO establishes a
radio connection between the vehicle and the
key.
The distance to the door handle from which
you wish to lock or unlock the vehicle must
not be greater than 1 m.
When starting the engine and whilst driving,
KEYLESS GO also checks whether a valid key
is in the vehicle by periodically establishing
radio contact. X
To unlock the vehicle: touch the inner
surface of the door handle.

Risk of accident
The vehicle can be braked when Distronic Plus
is activated. For this reason, deactivate Dis-
tronic Plus if the vehicle is to be set in motion
by other means (e.g. in a car wash or by tow-
ing).
You can activate Distronic Plus in the follow-
ing circumstances:
R after the engine has been running for about
two minutes
R if the parking brake is not applied
R if ESP ®
is activated
R if the automatic transmission* is in position

from Pto Dor your seat belt is fastened.
R if the front-passenger door and the rear
doors are closed
Activating while driving
When driving at speeds below 30 km/h, you
can only activate Distronic Plus if the vehicle
in front has been detected and is shown in the
multi-function display. If the vehicle in front is
not shown in the multi-function display and is
no longer being detected, because it has changed lanes, for example, Distronic Plus is
deactivated and a tone sounds.

vehicle in front, but only up to the stored
speed.
i If you do not fully release the accelerator
pedal, the DISTRONIC PLUS suspended
message appears in the multi-function dis-
play. The set distance to a slower-moving
vehicle in front will then not be maintained.
You will be driving at the speed you deter-
mine by the position of the accelerator
pedal.
Activating when driving towards a sta-
tionary vehicle
If the vehicle in front of you is stationary, you
can only activate Distronic Plus once your
vehicle is stationary as well.
X Briefly pull the cruise control lever towards
you ?.
Distronic Plus is selected.
i Distronic Plus can only be activated at
under 30 km/hi f a vehicle in front has been
detected. Therefore, the Distronic Plus dis-
tance display in the instrument cluster
should be activated.

Risk of injury
Make sure that nobody can become trapped
as you close the bonnet.
X Lower the bonnet and let it fall from a
height of approximately 20 cm.
X Check that the bonnet has engaged prop-
erly.
i If the bonnet can be raised slightly, it is
not properly engaged. Open it again and
close it with a little more force. Engine oil
Depending on driving style, the vehicle con-
sumes up to 0.8 l oil per 1,000 km. The oil
consumption may be higher than this when
the vehicle is new or if you frequently drive at
high engine speeds.
Checking the engine oil level Before checking the engine oil level the fol-
lowing conditions for the vehicle should be
met:
R the vehicle should be parked on level
ground.
R the engine should be switched off for at
least five minutes if the engine is at normal
operating temperature.
R the engine should be switched off for at
least 30 minutes if the engine is not at
operating temperature (i.e. if you only start
the engine briefly).
Depending on the engine, the oil dipstick may
be installed at a different location. 220

Topping up the engine oil H
Environmental note
When topping up the oil, take care not to spill
any. Oil must not be allowed to escape into
the soil or waterways. You would otherwise be
damaging the environment. Cap (example)
X
Turn cap :anti-clockwise and remove.
X Top up with the amount of oil required
(Y page 336). i
The difference in quantity between the
minimum mark and maximum mark is
approximately 2 litres.
i On vehicles with a 4-cylinder petrol
engine and vehicles with an 8-cylinder pet-
rol engine, the difference between the MIN
mark and the MAX mark is approximately
1.5 litres.
! Do not add too much oil. If too much oil
is added and the oil level is above the max-
imum mark on the dipstick, the engine or
catalytic converter could be damaged.
Have excess oil siphoned off.
X Replace cap :on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely.
For further information on engine oil, see
(Y page 336). Coolant
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
X Turn the key to position 2(Y page 75) in
the ignition lock.
X Check the coolant temperature gauge in
the instrument cluster. G
Risk of injury
The cooling system is pressurised. Therefore,
only unscrew the cap once the engine has
cooled down. The coolant temperature gauge
must display less than 70 †. Otherwise, you
could be scalded if hot coolant escapes. Engine compartment

i
On vehicles without level control, the
height of the ball coupling will alter accord-
ing to the load placed on the vehicle. If nec-
essary, use a trailer with a height-adjusta-
ble drawbar.
Coupling up a trailer G
Risk of injury
Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your hand could
become trapped between the bumper and
trailer drawbar.
! Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound-
ing of the overrun brake.
X Position the trailer level behind the vehicle.
X Couple up the trailer.
X Establish the electrical connection
between the vehicle and the trailer.
Driving tips G
Risk of accident
If the Check trailer hitch locking
mechanism message appears in the multi-
function display while the vehicle is in motion,
pull over immediately and check whether the
ball coupling is correctly engaged.
i Observe the notes on ESP ®
trailer stabi-
lisation (Y page 60).
In Germany, the maximum permissible speed
for vehicle/trailer combinations depends on
the type of trailer and is either 80 km/h or
100 km/h. Before beginning the journey,
check the trailer's documents to see what the
maximum permitted speed is. G
Risk of accident
Always observe the maximum speed permit-
ted in Germany for vehicle/trailer combina-
tions, even in countries where higher speeds are permitted. This lowers the risk of an acci-
dent.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
to when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R consumes more fuel
On long and steep downhill gradients you
must select a lower gear in good time, or on
vehicles with automatic transmission*, select
shift range 1,2or 3.
i This also applies if you have activated
cruise control, Speedtronic or Distronic
Plus*.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously. G
Risk of accident
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. 236

Risk of injury
The jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed.
You must use axle stands if you are carrying
out work on the vehicle.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar objects as a jack underlay.
The vehicle could otherwise fall off the jack
and seriously injure you.
Do not start the engine at any time while a
wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise the
vehicle as described, it could slip off the jack Where will I find...?
