Steering wheel gearshift control
one-touch gearshifting
With the gear selector lever in drive posi-
tion D and driving in shift program C or S,
you can limit or extend the gear range.
With the MAN shift program activated, you
can use the steering wheel gearshift con-
trol to manually shift the gears.
The steering wheel gearshift paddles are
located on the left and right side of the
steering wheel.
Steering wheel gearshift paddles
1 Left paddle: limiting gear range or
downshift (in shift program MAN)
2 Right paddle: extending gear range or
upshift (in shift program MAN)
The following instructions describe opera-
tion of the gear selector lever when driving
in the shift program C or S.
Limiting gear range
̈ Briefly pull left shift paddle 1.
The transmission will shift to the next
lower gear as permitted by the shift
program. This action simultaneously
limits the gear range of the transmis-
sion (
page 174).

For information on using the steering wheel
gearshift control in shift program MAN, see
“Manual shift program” (
page 178).
!
Allow engine to warm up under low load use.
Do not place full load on the engine until the
operating temperature has been reached.
Shift into reverse gear R or park position P only
when the vehicle is stopped.
Avoid spinning of a drive wheel for an extended
period when driving off on slippery road
surfaces. This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
i
You cannot shift with the steering wheel
gearshift paddles when the gear selector lever is
in park position P, neutral position N or reverse
gear R.
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.
