Notes on breaking-in a new vehicle
Important safety notes
In certain driving and driving safety sys-
tems, the sensors adjust automatically while
a certain distance is being driven after the
vehicle has been delivered or after repairs.
Full system effectiveness is not reached until
the end of this teach-in procedure.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate for this by applying greater force to the brake pedal.
The first 1000 miles (1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
RYou should therefore drive at varying vehi-
cle and engine speeds for the first
1000 miles (1500 km).
RAvoid heavy loads, e.g. driving at full
throttle, during this period.
RChange gear in good time, before the tach-ometer needle is 00C3of the way to the red
area of the tachometer.
RDo not manually shift to a lower gear to
brake the vehicle.
RVehicles with automatic transmission: if
possible, do not depress the accelerator pedal beyond the pressure point (kick-
down).
RVehicles with automatic transmission:
ideally, for the first 1000 miles(1500 km),
drive in program
E(Comfort).
After 1000 miles (1500 km), you can increase
the engine speed gradually and bring the
vehicle to full speed.
You should also observe these notes on run-
ning-in if the engine or parts of the drive
train on your vehicle have been replaced.
Observe the maximum permissible speed.
Driving
Important safety notes
GWARNING
Objects in the driver's footwell can
restrict the pedal travel or obstruct a
depressed pedal. The operating and road
safety of the vehicle is jeopardized. There
is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats securely and as specified in order to
ensure sufficient clearance for the pedals.
Do not use loose floormats and do not place
floormats on top of one another.
GWARNING
Unsuitable footwear can hinder correct
usage of the pedals, e.g.:
Rshoes with thick soles
Rshoes with high heels
Rslippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
GWARNING
If you switch off the ignition while driv-
ing, safety-relevant functions are only
available with limitations, or not at all.
This could affect, for example, the power

>> Driving and parking.

Transmission positions
0045Park position
This prevents the vehicle from
rolling away when stopped.
Only shift the transmission into
positionP(
Ypage 92) when the
vehicle is stationary. The parking
lock should not be used as a brake
when parking. Always apply the
parking brake in addition to the
parking lock in order to secure the
vehicle.
The key can only be removed if the
transmission is in position P. If
the SmartKey is removed from the
ignition lock, the selector lever is
locked.
In the event of a malfunction of the
vehicle's electronics, the trans-
mission may lock. Information on
manually disconnecting the selec-
tor lever lock (
Ypage 97).
Have the vehicle electronics
checked immediately at a quali-
fied specialist workshop.
0046Reverse gear
Only shift the transmission into
position Rwhen the vehicle is sta-
tionary.
0044Neutral
Do not shift the transmission to N
while driving. Otherwise, the
automatic transmission could be
damaged.
No power is transmitted from the
engine to the drive wheels.
Releasing the parking brake and
brake pedal will allow you to move
the vehicle freely, e.g. to push it or
tow it away.
If esp
®is deactivated or faulty:
shift the transmission to position
N if the vehicle is in danger of
skidding, e.g. on icy roads.
!Rolling in neutral Ncan dam-
age the drive train.
003ADrive
The automatic transmission
changes gear automatically. All
forward gears are available.
Driving tips
Changing gear
The automatic transmission shifts to the
individual gears automatically when it is in
transmission position D. This automatic
gearshifting behavior is determined by:
Rthe selected drive program:
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts
