Faster

Briefly tip the cruise control lever in the
direction of arrow1.
Slower

Briefly tip the cruise control lever in the
direction of arrow2.
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to preset
speed can cause an accident and/or serious
personal injury to you and others.
iDepressing the accelerator pedal does
not deactivate cruise control. After
brief acceleration (e.g. for passing),
cruise control will resume the last
speed set.
iVehicles with automatic transmission:
When you use the cruise control lever
to decelerate, the transmission will au-
tomatically downshift if the engine’s
braking power does not brake the vehi-
cle sufficiently.

Turn key in the starter switch to
position1 or2.

Slide cover2 rearward.

Push in cigarette lighter1.
The lighter will pop out automatically
when hot.
Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
The external antenna must be approved by
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Center for informa-
tion on the installation of an approved
external antenna. Refer to the radio trans-
mitter operation instructions regarding use
of an external antenna.
Warning!
G
Never touch the heating element or sides of
the lighter; they are extremely hot. Hold the
knob only.
When leaving the vehicle, always remove the
key from the starter switch, and lock your
vehicle. Do not leave children unattended in
the vehicle, or with access to an unlocked
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and/or serious
personal injury.iThe lighter socket can be used to ac-
commodate electrical accessories up
to a maximum 85 W.
Warning!
G
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, pos-
sibly resulting in an accident and personal
injury.

222 OperationThe first 1 000 miles (1 500 km)In the “Operation” section you will find de-
tailed information on operating, maintain-
ing and caring for your vehicle.
The first 1 000 miles (1 500 km)The more cautiously you treat your vehicle
during the break-in period, the more satis-
fied you will be with its performance later
on.

Drive your vehicle during the first
1000 miles (1500 km) at varying but
moderate vehicle and engine speeds.


During this period, avoid heavy loads
(full throttle driving) and excessive
engine speeds (no more than
2/3 of
maximum rpm in each gear).


Shift gears in a timely manner.


Avoid accelerating by kick-down.


Do not attempt to slow the vehicle
down by shifting to a lower gear using
the selector lever.


Select positions3, 2 or1 only when
driving at moderate speeds (for hill
driving).
After 1 000 miles (1 500 km) you may
gradually increase vehicle and engine
speeds to the permissible maximum.All of the above instructions, as may apply
to your vehicle type, also apply when
driving the first 1 000 miles (1 500 km)
after the engine or the rear differential has
been replaced
!Additional instructions for AMG
vehicles:

During the first 1 000 miles
(1 500 km), do not exceed a speed
of 85 mph (140 km/h).


During this period, avoid engine
speeds above 4 500 rpm in each
gear.
iAlways obey applicable speed limits.

223 Operation
Driving instructions
Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:

Keep tires at the recommended infla-
tion pressures.


Remove unnecessary loads.


Remove roof rack when not in use.


Allow engine to warm up under low
load use.


Avoid frequent acceleration and decel-
eration.


Have all maintenance work performed
at regular intervals by an authorized
Mercedes-Benz Center.
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly country.
Drinking and driving
Pedals
Warning!
G
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgement.
The possibility of a serious or even fatal ac-
cident is sharply increased when you drink
or take drugs and drive.
Please don’t drink or take drugs and drive or
allow anyone to drive after drinking or taking
drugs.
Warning!
G
Keep driver’s foot area clear at all times. Ob-
jects stored in this area may impair pedal
movement.

224 OperationDriving instructionsPower assistanceBrakesTo help prevent brake disk corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes.
If your brake system is normally only
subject to moderate loads, you should
occasionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads. If the parking brake is released and the
brake warning lamp in the instrument clus-
ter stays on, the brake fluid level in the res-
ervoir is too low.
Brake pad wear or a leak in the system may
be the reason for low brake fluid in the res-
ervoir.
Have the brake system inspected at an au-
thorized Mercedes-Benz Center immedi-
ately.
All checks and service work on the brake
system should be carried out by an autho-
rized Mercedes-Benz Center.
Only install brake pads and brake fluid
recommended by Mercedes-Benz.Warning!
G
When the engine is not running, the brake
and steering systems are without power as-
sistance. Under these circumstances, a
much greater effort is necessary to stop or
steer the vehicleWarning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking ef-
fect. Maintain a safe distance from vehicles
in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating,
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an acci-
dent.
!Be very careful not to endanger other
road users when you apply the brakes.
Refer to the description of the Brake
Assist System (BAS) (
page 74).

225 Operation
Driving instructions
After hard braking, it is advisable to drive
on for some time, rather than immediately
parking, so that the air stream will cool
down the brakes faster.
Driving off
Apply the 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 oper-
ating temperature has been reached.
When starting off on a slippery surface, do
not allow one drive wheel to spin for an ex-
tended 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
Warning!
G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
can result in an accident.!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 pre-
vent overheating of the brakes and re-
duces brake pad wear.
!Simultaneously depressing the
accelerator pedal and applying the
brake reduces engine performance and
causes premature brake and drivetrain
wear.
!Set the parking brake whenever park-
ing or leaving the vehicle. In addition,
move selector lever to positionP (man-
ual transmission: first or reverse gear).
In addition, when parking on hills,
always turn front wheels towards road
curb.
