You can open the doors from the inside at
any time.
You can also deactivate the automatic lock-
ing feature
(Y page 105).
Manual transmission X
Depress the clutch pedal.
X Shift to either first or reverse gear.
X Slowly release the clutch pedal and
depress the accelerator pedal.
! Change gear in good time and avoid spin-
ning the wheels. You could otherwise dam-
age the vehicle.
Automatic transmission *i
It is only possible to move the selector
lever to the desired position if you depres s
the brake pedal. Only then is the selector
lever lock released.
X Depress the brake pedal and hold it down.
X Release the handbrake .
X Move the selector lever to position Dor R.
i Wait for the shift process to complet e
before pulling away. X
Release the brake pedal .
X Carefully depress the accelerator pedal.
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly. Parking

Risk of fire
Make sure that the exhaust system doe s
not under any circumstances come into
contact with easily ignitable material such
as dry grass or petrol. The material could
otherwise ignite and set the vehicle on fire. Handbrake 1

Risk of injury
Cruise control brakes automatically in
order to avoid exceeding the set speed. As
it does so, the brake pedal is depressed. Do
not place your foot under the brake pedal
as it could become trapped .
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 accelerato r
pedal.
Cruise control is activated. The vehicle
automatically maintains the stored speed.
i Cruise control may be unable to maintai n
the stored speed on uphill gradients. Th e
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by
automatically applying the brakes.
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 as long as no gear is
selected.
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.
Resuming the last speed stored G
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 yo u
or others.
X Briefly pull the cruise control lever towards
you 3.
X Remove your foot from the accelerato r
pedal.
Cruise control is activated and adjusts the
vehicle's speed to the last speed stored. 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 Deceleration of the vehicle by means of
the cruise control lever is assisted by auto-
matic application of the brakes .
Vehicles with automatic transmission*:
On long downhill gradients, the automatic
transmission shifts down as a further meas-
ure. Controls

Making fine adjustments in 1 km/h
increments 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 you apply the handbrake
R you are driving at less than 30 km/h R
ESP ®
is intervening or you deactivat e
ESP ®
R you depress the clutch pedal for more than
seven seconds on vehicles with a manual
transmissio n
R you move the selector lever to Nin vehicles
with automatic transmission* while drivin g
i The last speed stored is cleared when you
switch off the engine. Speedtronic
Speedtronic brakes automatically so that you
do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must shift to a lower gear
in good time or select shift range 1,2 or 3in
vehicles with automatic transmission*. In this
way you will make use of the braking effect of
the engine, which relieves the load on the
brake system and prevents the brakes fro m
overheating and wearing too quickly. If you
need additional braking, depress the brake
pedal repeatedly rather than continuously. 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. Thi s
could cause the drive wheels to lose thei r
grip and the vehicle could skid.
You can set a variable or permanent limit
speed:
R Variable for speed limits, e.g. in built-up
areas (Y page 113 )
R Permanent for long-term speed restric-
tions, e.g. for driving on winter tyres
( Y page 114 ) G
Risk of accident
Speedtronic is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in goo d
time. Controls

Towing and tow-startin
g236 Towing the vehicle
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
With towing distances over 50 km, the
entire vehicle needs to be lifted up and
transported.
! The engine must be switched off (key in
ignition lock in position 0or position 1) if
the vehicle is being towed with the fron t
axle raised or if the parking brake is bein g
tested on a dynamometer. Intervention by
ESP ®
could otherwise damage the brake
system.
Vehicles with manual transmission X
Turn the key to position 2in the ignition
lock .
X Shift to neutral .
Vehicles with automatic transmission *X
Turn the key to position 2in the ignition
lock .
X Move the selector lever to N. Tow-starting (emergency engine
starting )
Please note:
R Vehicles with an automatic transmission*
must not be tow-started.
R The battery must be connected.
R The engine and catalytic converter must be
cold.
R Avoid repeated and lengthy starting
attempts .
Vehicles with manual transmission X
Turn the key to position 2in the ignition
lock .
X Shift to neutral .
X Tow the vehicle or let it roll.
X Shift to a suitable gear and bring the clutch
pedal up slowly. Do not depress the accel-
erator pedal.
The engine is started. Removing the towing ey
e
X Take the wheel wrench from the vehicle
tool kit (Y page 172).
X Insert the wheel wrench handle into the
towing eye and turn it anti-clockwise.
X Unscrew the towing eye.
X Replace the cover and press it until it
engages.
X Return the towing eye and the whee l
wrench to the vehicle tool kit . Transporting the vehicle
The towing eyes can be used to pull the vehi-
cle onto a trailer or transporter for transport-
ing purposes.
! Only lash the vehicle down by the wheels
or wheel rims, not by parts of the vehicl e
such as axle or steering components. The
vehicle could otherwise be damaged.
Vehicles with manual transmission X
Shift to neutral . Practical advice
