A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we
recommend that you pull over to a safe
location and stop before placing or taking a
telephone call. If you choose to use the
telephone while driving, please use the
hands-free device and only use the
telephone when weather, road and traffic
conditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a
vehicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system,
possibly resulting in an accident and
personal injury.

Manual transmission
 Manual transmission
For more information on driving with a
manual transmission, see “Manual trans-
mission” (
page 48).
Warning!
G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in 1st or reverse
gear and parking brake engaged is danger-
ous. Also, when parked on an incline, an en-
gaged 1st or reverse gear alone may not
prevent your vehicle from moving, possibly
hitting people or objects.
Always set the parking brake in addition to
engaging first or reverse gear (
page 56).
When parked on an incline, turn the front
wheel towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay, or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could move the gearshift lever, which could
result in an accident and/or serious injury.Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.

160 Controls in detailAutomatic transmission*When the gear selector lever is in
positionD, you can influence transmission
shifting by:

limiting the gear range


changing gears manually
One-touch gearshifting
Even with an automatic transmission you
can change the gears manually when the
gear selector lever is in position D.
Downshifting
Briefly press the gear selector lever to
the left in the D-direction.
The transmission will shift from the current
gear to the next lower gear. This action
simultaneously limits the gear range of the
transmission (
page 161). Upshifting

Briefly press the gear selector lever to
the right in the
D+direction.
The transmission will shift from the current
gear to the next higher gear as permitted
by the shift program. This action simul-
taneously extends the gear range of the
transmission.
Warning!
G
It is dangerous to shift the gear selector
lever out of P or N if the engine speed is
higher than idle speed. If your foot is not
firmly on the brake pedal, the vehicle could
accelerate quickly forward or reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.
iTo avoid overrevving the engine when
the gear selector lever is moved to
the D-direction, the transmission will
not shift to a lower gear if the engine’s
max. speed would be exceeded.

other reason with gear selector lever
in N can result in transmission damage
that is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Getting out of your vehicle with the gear
selector lever not fully engaged in position P
is dangerous. Also, position P alone is not
intended to or capable of preventing your
vehicle from moving, possibly hitting people
or objects.
Always set the parking brake in addition to
shifting to position P (
page 50).
When parked on an incline, turn the front
wheels towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay, or
leaves can come into contact with the hot

When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with

could move the gear selector lever from
position P, which could result in an accident
and/or serious personal injury.
