Wa r n i n g !
When leaving the vehicle always remove the key
from the steering lock, and lock the vehicle. Do not
leave children unattended in the vehicle, or with
access to an unlocked vehicle. Unsupervised use of
vehicle equipment may cause serious personal
injury.

171 Automatic transmission
Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Upshift through 2nd gear only. For driving in
mountainous regions or under extreme operating
conditions. This gear selection will allow use of
the engine’s braking power when descending
steep grades.
Use this position, which makes maximum use of
the engine’s braking effect, while descending
very steep or lengthy downgrades and only at
speeds below 40 mph (60 km/h).
Important!
With selector lever in position “D”, “4” or “3”, upshifting
from 1st to 2nd to 3rd gear is delayed depending on
vehicle speed and engine temperature. This allows the
catalytic converter to heat up more q uickly to operating
temperatures.
During the brief warm-up period this delayed upshift
and increased engine noise might be perceived as a
malfunction. However, neither the engine nor
transmission are negatively affected by this mode of
operation.
The delayed upshift is effective with vehicle speeds
below 31 mph (50 km/h) at partial throttle and engine
temperatures below 95°F (35°C).To avoid overrevving the engine when the selector lever
is moved to a lower driving range, the transmission will
not shift to a lower gear, if the engine’s speed limit
would be exceeded. In this case there will be no
downshift, even when the vehicle speed reaches the
engine’s speed limit of that gear, e.g. by applying the
service brakes. Continue driving in the usual manner.
The transmission will then shift down automatically.
To prevent the engine from laboring at low RPM when
driving uphill gradients or with your vehicle heavily
loaded, the automatic transmission will downshift when
necessary to maintain engine RPM within the best
torque range.
Wa r n i n 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.

Maneuvering
To maneuver in tight areas, e.g. when pulling into a
parking space, control the vehicle speed by gradually
releasing the brakes. Accelerate gently and never
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow),
alternately shift from forward to reverse, while applying
only slight partial throttle.
Rocking a vehicle free in this manner may cause the
ABS malfunction indicator lamp to come on. Turn off
and restart the engine to clear the malfunction
indication.
Stopping
For brief stops, e.g. at traffic lights, leave the
transmission in gear and hold vehicle with the service
brake.
For longer stops with the engine idling, shift into “N”
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not
hold it with the accelerator, use the brake. This avoids
unnecessary transmission heat build up.
Wa r n i n g !
Getting out of your vehicle with the selector lever
not fully engaged in position “P” is dangerous.
Also, when parked on an incline, position “P” alone
may not prevent your vehicle from moving,
possibly hitting people or objects.Always set the parking brake in addition to shifting
to position “P”.When parked on an incline, also turn front wheel
towards the road curb.When leaving the vehicle always remove the key
from the steering lock, and lock the vehicle. Do not
leave children unattended in the vehicle, or with
access to an unlocked vehicle. Children could move
the selector lever from position “P”, which could
result in an accident or serious injury.

Caution!
When driving down long and steep grades, relieve the
load on the brakes by shifting into a lower gear to use
the engine’s braking power. This helps prevent
overheating of the brakes and reduces brake pad wear.
After hard braking, it is advisable to drive on for some
time, rather than immediately parking, so the air stream
will cool down the brakes faster.
Driving off
Apply the service brakes to test them briefly after
driving off. Perform this procedure only when the road
is clear of other traffic.
Warm up the engine smoothly. Do not place full load on
the engine until the operating temperature has been
reached.
When starting off on a slippery surface, do not allow one
drive wheel to spin for an extended period with the ESP
switched off. Doing so may cause serious damage to the
drive train which is not covered by the Mercedes-Benz
Limited Warranty.Parking
Important!
Always engage the parking brake whenever parking or
leaving the vehicle. In addition, move selector lever to
position “P”.
When parking on hills, always set the parking brake.
Wa r n i n g !
To reduce the risk of personal injury as a result of
vehicle movement, before
turning off the engine
and leaving the vehicle, always:
1. Keep right foot on the service brake pedal.
2. Firmly engage parking brake.
3. Move the selector lever to position “P”
4. Slowly release the service brake pedal.
5. Turn front wheels towards the road curb.
6. Turn the key to steering lock position 0 and
remove.
7. Take the key and lock vehicle when leaving.

Specified tire pressures must be maintained. This
applies particularly if the tires are subjected to high
loads (e.g. high speeds, heavy loads, high ambient
temperatures).
Aquaplaning
Depending on the depth of the water layer on the road,
aquaplaning may occur, even at low speeds and with
new tires. Reduce vehicle speed, avoid track grooves in
the road and apply brakes cautiously in the rain.Tire traction
The safe speed on a wet, snow covered or icy road is
always lower than on a dry road.
You should pay particular attention to the condition of
the road whenever the outside temperatures are close to
the freezing point.
We recommend M+S rated radial-ply tires for the winter
season for all four wheels to insure normal balanced
handling characteristics. On packed snow, they can
reduce your stopping distance as compared with
summer tires. Stopping distance, however, is still
considerably greater than when the road is not snow or
ice covered.
Wa r n i n g !
Do not drive with a flat tire. A flat tire affects the
ability to steer or brake the vehicle. You may lose
control of the vehicle. Continued driving with a flat
tire or driving at high speed with a flat tire will
cause excessive heat build-up and possibly a fire.
Wa r n i n g !
If ice has formed on the road, tire traction will be
substantially reduced. Under such weather
conditions, drive, steer and brake with extreme
caution.

cluster displayPractical hints Car care Index Tire speed rating
Vehicles without Sport Package:
Your vehicle is factory equipped with “W”-rated tires,
which have a speed rating of 168 mph (270 km/h).
Vehicles with Sport Package:
Your vehicle is factory equipped with “V”-rated tires,
which are permissible for speeds over 149 mph
(240 km/h).
Despite the tire rating, local speed limits should be
obeyed. Use prudent driving speeds appropriate to
prevailing conditions.Snow chains
Use only snow chains that are tested and recommended
by Mercedes-Benz. Your authorized Mercedes-Benz
Center will be glad to advise you on this subject.
Chains should only be used on the rear wheels. Follow
the manufacturer’s mounting instructions.
Snow chains should only be driven on snow covered
roads at speeds not to exceed 30 mph (50 km/h).
Remove chains as soon as possible when driving on
roads without snow.
When driving with snow chains, press the ESP control
switch to OFF, see page 194.
Vehicles with Sport Package
Use of snow chains is not permissible with tire sizes
245/40 ZR 18 or 275/35 ZR 18.
Wa r n i n g !
Even when permitted by law, never operate a
vehicle at speeds greater than the maximum speed
rating of the tires.Exceeding the maximum speed for which tires are
rated can lead to sudden tire failure causing loss of
vehicle control and resulting in personal injury
and possible death.
