124Driving and operatingEngine exhaust9Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on pages 3 144, 3 202 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
Manual transmission
To engage reverse, with the vehicle
stationary wait 3 seconds after
depressing the clutch pedal and then
press the release button on the
selector lever and engage the gear.
If the gear does not engage, set the
lever to neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch
pedal completely. Do not use the
pedal as a foot rest.

Driving and operating131
Reduce speed
With cruise control active, hold thumb wheel turned to SET/- or briefly turn to
SET/- repeatedly: speed decreases
continuously or in small increments.
Deactivation
Press button y, control indicator m in
instrument cluster illuminates white.
Cruise control is deactivated. Last
used set speed is stored in memory
for later speed resume.
Automatic deactivation:
■ vehicle speed below approx. 20 mph,
■ vehicle speed above approx. 125 mph,
■ the brake pedal is depressed,
■ the clutch pedal is depressed for a few seconds,
■ engine speed 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.
Pressing button L for activating
speed limiter or switching off the
ignition also switches off cruise
control and deletes the stored speed.Speed limiter
The speed limiter prevents the
vehicle 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.

Vehicle care155
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 3 195.
Vehicle battery Vehicles without stop-start system
will be 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 3 109.
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.
In vehicles with stop-start system, be
sure to have the AGM (Absorptive
Glass Mat) battery replaced with
another AGM battery

After having changed defective fuses
close the fuse box cover and press
until it engages.
If the fuse box cover is not closed
correctly, malfunction may occur.
Instrument panel fuse box
In left-hand drive vehicles, the fuse
box is behind the light switch in the
instrument panel.
Hold the handle, then pull and fold
down the light switch.

196Service and maintenance
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 199.
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 3 199.
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.
