Driving and operating147Starting the vehicle at lowtemperatures
Starting the engine without additional
heaters is possible down to -25 °С for diesel engines and -30 °C for petrol
engines. Required is an engine oil
with the correct viscosity, the correct fuel, performed services and a
sufficiently charged vehicle battery.
With temperatures below -30 °C the
automatic transmission requires a
warming phase of approx.
five minutes. The selector lever must
be in position P.
Heating functionalities Notice
Individual heating functionalities,
such as heated seats or heated
steering wheel, may be temporarily
unavailable in the event of electrical
loading constraints. Functions will
be resumed after some minutes.Turbo engine warm-up
Upon start-up, engine available
torque may be limited for a short time,
especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully protect the engine.
Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator pedal is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam.Activation
The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.
The system is ready to operate when
the LED in the button Ò is not

Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to
save power.Restart of the engine by the driver
Vehicles with manual transmission
Depress the clutch pedal without
depressing the brake pedal to restart the engine.
Vehicles with automatic transmission The engine is restarted if
● the brake pedal is released while
the selector lever is in position D
or M
● or the brake pedal is released or the selector lever is in position N
when the selector lever is moved
to position D or M
● or the selector lever is moved to position R.
Restart of the engine by the stop- start system

switched off 3 213.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Notice
In the event of an accident with airbag deployment, the engine is
switched off automatically if the
vehicle comes to a standstill within a
certain time.
In countries with extreme low
temperatures it may be necessary to park the vehicle without applied
parking brake. Make sure to park the
vehicle on a level surface.

Driving and operating151Engine 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.
Exhaust filter
Automatic cleaning process
The exhaust filter system filters soot particles out of the exhaust gases.
The start of saturation of the exhaust
filter is indicated by the temporary
illumination of % or C ,
accompanied by a message in the
Driver Information Centre.
As soon as the traffic conditions
permit, regenerate the filter by driving at a vehicle speed of at least 40 mph
until the control indicator
extinguishes.
Notice
On a new vehicle, the first exhaust
filter regeneration operations may
be accompanied by a burning smell,
which is normal. Following
prolonged operation of the vehicle at very low speed or at idle, water
vapour can be emitted at the
exhaust on acceleration. This does
not affect the behaviour of the
vehicle or the environment.
Cleaning process not possible
If % or C stays on, accompanied
by an audible signal and a message,
this indicates that the exhaust filter
additive level is too low.
The reservoir must be topped-up
without delay. Seek the assistance of
a workshop.Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 202, 3 260 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.

Driving and operating153Additionally, control indicator u
will flash and a chime will sound. Refill AdBlue as soon as possible
before the AdBlue tank is
completely empty. Otherwise, a
restart of the engine will not be
possible.
When driving, the chime sounds
and the message is displayed
every 6 miles until the additive
tank has been topped-up.
4. The last warning level is entered when the AdBlue tank is empty.
Restart of the engine is not
possible. The following warning
message will be displayed:
Top up emissions additive:
Starting prevented
Additionally, control indicator u
will flash and a chime will sound.
Refill the tank to a level of at least 5 l of AdBlue, otherwise restarting
of the engine is not possible.
Notice
For D16DT engines, different levels
apply.High emission warnings
In the event of a fault with the
emissions control system, different
messages are displayed in the Driver
Information Centre. The messages
and the restrictions are a legal
requirement.
1. If a fault is detected for the first time, the warning Emissions fault
is displayed.
Additionally, control indicators u,
R and Z will illuminate and a
chime will sound. Driving is
possible without any restrictions.
If it is a temporary fault, the alert
disappears during the next
journey, after self-diagnosis of the
emissions control system.
2. If the fault is confirmed by the emission control system, the
following message will be
displayed:
Emissions fault: Starting
prevented in 650 miles .
Additionally, control indicators u,
C and Z will illuminate and a
chime will sound.When driving, the message is
displayed every 30 s while the
fault persists.
3. If the last warning level is entered,
the following warning message
will be displayed:
Emissions fault: Starting
prevented
Additionally, control indicators u,
C and Z will illuminate and a
chime will sound.
Consult a workshop for
assistance.
Refilling AdBlueCaution
Only use AdBlue that complies
with European standards
DIN 70 070 and ISO 22241-1.
Do not use additives.
Do not dilute AdBlue.
Otherwise the selective catalytic
reduction system could be
damaged.

154Driving and operatingNotice
Whenever a filling pump with a
nozzle for passenger cars is not
available at a filling station, use only
AdBlue bottles or canisters with a
sealed refill adapter for refilling, to
prevent splashback and overspill,
and in order to ensure that the fumes
from the tank are captured and do
not emerge. AdBlue in bottles or
canisters is available in many filling
stations and can be purchased e.g. at Vauxhall dealers and other retail
outlets.
Since AdBlue has a limited
durability, check the date of expiry
before refilling.
Notice
Refill the tank to a level of at least
5 l to ensure that the new AdBlue
level is being detected.
In case AdBlue refill is not
successfully detected:1. Continuously drive the vehicle for 10 min making sure that
vehicle speed is always higher
than 12 mph.
2. If AdBlue refill is detected successfully, AdBlue supply-
driven warnings or limitations will
disappear.
If AdBlue refill is still not detected, seek the assistance of a workshop.
If AdBlue must be refilled at
temperatures below -11 °C, the
refilling of AdBlue may not be
detected by the system. In this
event, park the vehicle in a space
with a higher ambient temperature
until AdBlue is liquified.
Notice
When unscrewing the protective cap
from the filler neck, ammonia fumes
may emerge. Do not inhale as the
fumes have a pungent smell. The
fumes are not harmful by inhalation.
The AdBlue tank should be filled
completely. This must be done if the
warning message regarding
prevention of an engine restart is
already displayed.The vehicle must be parked on a level surface.
The filler neck for AdBlue is located
behind the fuel filler flap, which is located at left rear side of the vehicle.
If the vehicle is equipped with an
electronic key system, the fuel filler
flap can only be opened if the vehicle
is unlocked.
1. Remove key from ignition switch.
2. Close all doors to avoid ammonia fumes entering the interior of the
vehicle.
3. Release the fuel filler flap by pushing the flap 3 204.

156Driving and operatingP:park position, front wheels are

When a gear is engaged, the vehicle
slowly begins to creep when the
brake is released.
Engine braking
To utilise the engine braking effect,select a lower gear when driving
downhill.
Rocking the vehicle Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the gear
selector between D and R in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking Apply the parking brake and select P.
Manual mode Manual mode M can be activated
from position D in each driving
situation and speed.
Press button M.
Pull steering wheel paddles to select
gears manually.

Driving and operating157Pull right paddle + to shift to a higher
gear.
Pull left paddle - to shift to a lower
gear.
Multiple pulls allow gears to be
skipped.
The selected gear is indicated in the
instrument cluster.
If a higher gear is selected when
vehicle speed is too low, or a lower
gear when vehicle speed is too high,
the shift is not executed. This can
cause a message in the Driver
Information Centre.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions.
Gear shift indication
The symbol R or S with a number
beside it is indicated when
gearshifting is recommended for fuel
saving reasons.
Shift indication appears only in
manual mode.Electronic driving
programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● Special programmes automatically adapt the shifting
points when driving up inclines or
down hills.
● In snowy or icy conditions or on other slippery surfaces, the
electronic transmission control
enables the driver to select
manually first, second or third gear for starting off.
Kickdown
Pressing down the accelerator pedal
beyond the kickdown detent will lead to maximum acceleration
independent of selected driving
mode. The transmission shifts to a
lower gear depending on engine speed.Fault
In the event of a fault a message is
displayed in the Driver Information
Centre.
Vehicle messages 3 114.
Electronic transmission control
enables only third gear. The
transmission no longer shifts
automatically.
Do not drive faster than 62 mph.
Have the cause of the fault remedied by a workshop.
Eco mode

Driving and operating159When clutch slip is detected for aspecific time, the engine power will be
reduced. A warning is displayed in the
Driver Information Centre. Release
the clutch.Caution
It is not advisable to drive with the hand resting on the selector lever.
Gear shift indication 3 104.
Stop-start system 3 147.
Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing the journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator m 3 103.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
When braking in an emergency, the
hazard warning flashers are switched
on automatically depending on the
force of deceleration. They are
switched off automatically the first
time you accelerate.
After starting off, the system performs a self-test which may be audible.
