Points to remember
You will find an illustration of the instrument

Risk of accident
No further messages can be displayed if the
instrument cluster and/or the multi-func-
tion display fails.
This means that you will not see information
about the driving situation, such as the
speed, outside temperature, warning/indi-
cator lamps, display messages or system
failures. The vehicle's handling character-
istics may be affected. Adjust your driving
style and speed accordingly.
Immediately consult a qualified specialist
workshop which has the necessary special-
ist knowledge and tools to carry out the
work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop. Cont

6 Deactivating cruise control Selecting cruise control X
Check whether LIM indicator lamp 2is off.
If it is off, cruise control is already selected.
If it is on, press the cruise control lever in
the direction of arrow 5.
LIM indicator lamp 2in the cruise control
lever goes out. Cruise control is selected.
Storing and maintaining the current
speed You can store the current speed if you are
driving faster than 30 km/
h.
X Accelerate the vehicle to the desired
speed.
X Briefly press the cruise control lever up
1 or down 4.
X Remove your foot from the accelerator
pedal.
Cruise control is activated. The vehicle
automatically maintains the stored speed.
i Cruise control may be unable to maintain
the stored speed on uphill and downhill
gradients. The stored speed is resumed
when the gradient levels out.
Vehicles with manual transmission: When selecting another gear, press the
accelerator pedal slightly to increase the
smoothness of the gear change.
When you depress the clutch pedal and
change to another gear, the engine speed
can increase slightly while no gear is selec-
ted.
R
always drive at adequate, but not exces-
sive, engine speeds.
R change gear in good time.
R if possible, do not change down several
gears at a time.

Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for
the current situation. Otherwise, sudden
acceleration or braking could endanger you
or others.
X Briefly pull the cruise control lever towards
you 3.
X Remove your foot from the accelerator
pedal.
Cruise control is activated and adjusts the
vehicle's speed to the last speed stored. Controls

Setting a speed X
Press the cruise control lever up 1for a
higher speed or down 4for a lower speed.
X Keep the cruise control lever pressed until
the desired speed is reached.
X Release the cruise control lever.
The new speed is stored.
i Cruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin-
ished overtaking.
i Vehicles with AUTOTRONIC*:
When you decelerate the vehicle using the
cruise control lever, AUTOTRONIC changes
down if deceleration is insufficient.
Making fine adjustments in
1 km/hincrements X
Briefly press the cruise control lever up
1 for a higher speed or down 4for a
lower speed.
The last speed stored is increased or
reduced. Deactivating cruise control There are several ways to deactivate cruise
control:
X
Briefly press the cruise control lever for-
wards 6.
or
X Brake.
or
X Briefly press the cruise control lever in the
direction of arrow 5.
Variable Speedtronic is selected. LIM indi-
cator lamp 2in the cruise control lever
lights up.
Cruise control is automatically deactivated if,
for example:
R aquaplaning is detected
R you press the clutch pedal for more than
four seconds on vehicles with a manual
transmission
R you move the selector lever to Nwhile driv-
ing in vehicles with AUTOTRONIC*
i The last speed stored is cleared when you
switch off the engine. Speedtronic*
Speedtronic is used to make sure that you do
not exceed a stored speed. You must select
a low gear in good time on long and steep
downhill gradients, especially if the vehicle is
laden or towing a trailer. By doing so you will
make use of the braking effect of the engine,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly. G
Risk of accident
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid. Controls

Jump-starting
266 Reconnecting the battery
! Always reconnect the battery in the
sequence described below. Never swap the
terminal clamps. You may otherwise dam-
age the vehicle electronics.
X Switch off all electrical consumers.
X Connect the positive terminal clamp and
secure the cover.
X Connect the negative terminal clamp.
X Connect the breather hose. Make sure that
a cell cap is fitted on the side.
i If the battery power supply has been inter-
rupted (e.g. if it has been reconnected), you
must carry out the following tasks:
R set the time (Y page 108).
R reset the function for folding the exterior
mirrors in/out automatically* by folding
the mirrors out once (Y page 71).
R reset the side windows (Y page 84) Jump-starting
If your vehicle's battery is discharged, the
engine can be jump-started from another
vehicle or from an external battery using jump
leads.
Observe the following points:
R Jump-starting may only be performed when
the engine and catalytic converter are cold.
R Do not start the engine if the battery is fro-
zen. Let the battery thaw first.
R Jump-starting may only be performed from
batteries with a nominal voltage of 12 V.
R Only use jump leads which have a sufficient
cross-section and insulated terminal
clamps.
i Jump leads and further information about
jump-starting can be obtained from any
Mercedes-Benz Service Centre.
! Avoid repeated and lengthy starting
attempts.
Never start the vehicle using a rapid battery
charger. G
Risk of injury
There is a risk of acid burns when jump-
starting a vehicle due to the gases which
escape from the battery. Do not lean over
the battery while the engine is being jump-
started. G
Risk of explosion
Gases escaping from the battery during
jump-starting may cause minor explosions.
Avoid creating sparks. Keep naked flames
away from the battery, and do not smoke.
Comply with safety precautions and take
protective measures when handling batter-
ies. You will find these under "Battery" in
the index.
X Make sure that the two vehicles do not
touch.
X Apply the parking brake.
X Manual transmission: engage neutral.
X AUTOTRONIC*: move the DIRECT SELECT
selector lever to P.
X Switch off all electrical consumers.
X Open the bonnet (Y page 171). Practical advice
