X Select the Standard display menu
(Y page 103).
X Press and hold the reset button on the left-
hand side of the instrument cluster until the
trip meter is reset. Rev counter
The red band in the rev counter indicates the
engine's overrevving range. The fuel supply is
interrupted to protect the engine when the
red band is reached.
! Do not drive in the overrevving range.
Doing so will damage the engine. H
Environmental note
Avoid driving at high engine speeds, as this
increases your vehicle's consumption
unnecessarily and pollutes the environ-
ment through increased emissions. Clock
On vehicles without an audio system or with
Audio 5*/Audio 20*, you can set the time
using the on-board computer (Y page 109). Outside temperature display
G
Risk of accident
The road surface may be icy, especially in
wooded areas or on bridges, even if tem-
peratures are just above freezing point. The
vehicle could skid if you fail to adapt your
driving style. You should therefore always
adapt your driving style and speed to suit
the weather conditions.
Changes in the outside temperature are dis-
played after a short delay. On-board computer
Points to remember
The on-board computer is activated as soon
as you turn the key to position 1in the ignition
lock. You can use the on-board computer to
call up information relating to your vehicle
and to make and adjust settings. G
Risk of accident
Only use the on-board computer when road
and traffic conditions permit. You would
otherwise be distracted and unable to con-
centrate properly on driving, and could
cause an accident. Multi-function steering wheel
You can control the multi-function display and
the settings in the on-board computer using
the buttons on the multi-function steering
wheel. Controls

Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R Cruise control* and Speedtronic*, which
are used to control the speed of the vehicle
R Parktronic * and active parking assist*,
which can help you to find a parking space,
to manoeuvre and park
R ECO Start-Stop function*, helps you to
save fuel
The ABS, BAS, adaptive brake lights, ESP ®
and STEER CONTROL driving safety systems
are described in the "Driving safety systems"
section ( Ypage 55). Cruise control*
Cruise control maintains a constant road
speed for you. You must select a low gear in
good time on long and steep downhill gradi-
ents, especially if the vehicle is laden or tow-
ing 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.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good
time. G
Risk of accident
Do not use cruise control:
R in road and traffic conditions which do
not allow you to maintain a constant
speed (e.g. heavy traffic or winding
roads). You could otherwise cause an
accident.
R on slippery roads. Braking or accelerat-
ing could cause the drive wheels to lose
traction and the vehicle could then skid.
R when there is poor visibility, e.g. due to
fog, heavy rain or snow
Cruise control lever You can operate cruise control and variable
Speedtronic with the cruise control lever. Controls

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.

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.

Cruise control is automatically deactivated if,
for example:
R aquaplaning is detected

four seconds on vehicles with a manual
transmission
R you move the selector lever to Nwhile driv-
ing in vehicles with AUTOTRONIC*

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
