134Driving and operating
Automatic deactivation:■ Vehicle speed is below approx. 20 mph.
■ Vehicle speed is above approx. 125 mph.
■ The brake pedal is depressed.
■ The clutch pedal is depressed for a
few seconds.
■ Engine speed is in a very low range.
■ The Traction Control system or Electronic Stability Control is
operating.
Resume stored speed
Turn thumb wheel to RES/+ at a
speed above 20 mph. The stored
speed will be obtained.
Switching off
Press button m, control indicator m in
instrument cluster extinguishes. The
stored speed is deleted.
Switching off the ignition also
switches off cruise control and
deletes the stored speed.Speed limiter
The speed limiter prevents thevehicle exceeding a preset maximum speed.
The maximum speed can be set at a
speed above 15 mph.
The driver can only accelerate up to
the preset speed. Deviations from the
limited speed may occur when driving
downhill.
The preset speed limit is displayed in
the top line of the Driver Information
Centre when the system is active.
ActivationPress button L. If cruise control has
been activated before, it is switched
off when speed limiter is activated
and the control indicator m
extinguishes.
Set speed limit
With speed limiter active, hold thumb
wheel turned to RES/+ or briefly turn
to RES/+ repeatedly until the desired
maximum speed is displayed in the
Driver Information Centre.
Alternatively accelerate to the desired speed and briefly turn thumb wheel to
SET/- : the current speed is stored as
maximum speed. Speed limit is
displayed in the Driver Information
Centre.

Vehicle care157
The brake fluid level must be betweenthe MIN and MAX marks.
If fluid level is below MIN seek the
assistance of a workshop.
Brake and clutch fluid 3 202.
Vehicle battery The vehicle is equipped with a lead
acid battery.
Vehicles with stop-start system will be
equipped with an AGM battery which
is not a lead acid battery.
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the vehicle battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
4 weeks can lead to vehicle battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
The anti-theft alarm siren must be
deactivated as follows: Switch the
ignition on then off, disconnect the
vehicle's battery within 15 seconds.
Battery discharge protection 3 110.
Replacing the vehicle battery
Notice
Any deviation from the instructions
given in this section may lead to
temporary deactivation of the stop-
start system.
When the vehicle battery is being
replaced, please ensure that there
are no open ventilation holes in the
vicinity of the positive terminal. If a
ventilation hole is open in this area, it
must be closed off with a dummy cap,
and the ventilation in the vicinity of the negative terminal must be opened.
Only use batteries that allow the fuse
box to be mounted above the vehicle
battery.
Vehicles with stop-start system
Be sure to have the AGM (Absorptive
Glass Mat) battery replaced with
another AGM battery.

Service and maintenance203
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 206.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 206.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.Coolant and antifreeze
Use only silicate-free long life coolant (LLC) antifreeze. Consult a
workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37 °C. This concentration
should be maintained all year round.
The use of additional coolant
additives that intend to give additional
corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional coolant additives will be rejected.
Brake and clutch fluid Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified
interval.
