Driving and operating165Engine 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.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification. The filter is cleaned
by periodically burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may
take up to 25 minutes. Typically it
needs between 7 and 12 minutes. Autostop is not available and fuel
consumption may be higher during
this period. The emission of smells and smoke during this process is
normal.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If the cleaning of the filter is required
and if previous driving conditions did
not enable automatic cleaning, it will
be indicated by control indicator %.
Simultaneously Diesel partic. filter is
full continue driving or warning
code 55 appears in the Driver
Information Centre.
% illuminates when diesel particle
filter is full. Start cleaning process as
soon as possible.
% flashes when diesel particle filter
has reached the maximum filling
level. Start cleaning process
immediately to avoid damage to the
engine.
Cleaning process
To activate cleaning process,
continue driving, keep engine speed
above 2000 revolutions per minute.
Shift down if necessary. Diesel
particle filter cleaning is then started.
If g illuminates additionally,
cleaning is not possible, seek the
assistance of a workshop.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.

168Driving and operatingManual mode
Move selector lever out of position D
towards the left and then forwards or backwards.
<=Shift to a higher gear.]=Shift to a lower gear.
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-Info-Display.
In manual mode no automatic shifting to a higher gear takes place at high
engine revolutions.
Electronic driving
programmes ■ Following a cold start, the operating
temperature programme increasesengine speed to quickly bring the
catalytic converter to the required
temperature.
■ The automatic neutral shift function
automatically shifts to idling when
the vehicle is stopped with a
forward gear engaged and the
brake pedal is pressed.
■ When SPORT mode is engaged, the vehicle shifts at higher engine
speeds (unless cruise control is
on). SPORT mode 3 176.■ Special programmes automatically
adapt the shifting points when
driving up inclines or down hills.
■ When starting off in snowy or icy conditions or on other slippery
surfaces, the electronic
transmission control selects a
higher gear automatically.
Kickdown If the accelerator pedal is pressed
down completely in automatic mode,
the transmission shifts to a lower gear depending on engine speed.
Fault In the event of a fault, g illuminates.
Additionally a code number or a
vehicle message is displayed in the
Driver Information Centre. Vehicle
messages 3 125.
The transmission no longer shifts
automatically. Continued travel is
possible with manual shifting.

brake and retry applying.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking
is required. Maximum brake force is
automatically reduced when the
brake pedal is released.Hill start assist
The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline, the brakes
remain on for a further two seconds.
The brakes release automatically as
soon as the vehicle begins to
accelerate.
The hill start assist is not active during
an Autostop.Ride control systems
Traction Control system
The Traction Control system (TC) is a
component of the Electronic Stability
Control (ESC) 3 174.
TC improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational after each engine
start as soon as the control indicator
b extinguishes.
When TC operates b flashes.

Driving and operating199
Functionality
When the vehicle passes a row of
cars and the system is activated, the
advanced parking assist system
begins searching for a suitable
parking slot. When a suitable slot is
detected, a visual feedback on the
Driver Information Centre and an
acoustic signal are given.
If the driver does not stop the vehicle
within 10 metres after a parking slot is
proposed, the system starts to search for another suitable parking slot.
The parking slot suggestion of the
system is accepted when the vehicle
is stopped by the driver within
10 metres after the "Stop" message is
given. The system calculates the
optimal route into the parking slot.
Then it manoeuvres the driver into the slot by giving detailed instructions.The instructions in the display show:
■ a hint when driving faster than 18 mph,
■ the demand to stop the vehicle, when a parking slot is detected,
■ the direction of driving during the parking manoeuvre,
■ the steering wheel position during parking,
■ for some of the instructions a progress bar is shown.

Vehicle care2239Danger
The ignition system and Xenon
headlights use extremely high

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.

Vehicle care227
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 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 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.

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 vehicle 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.
An AGM battery can be identified by
the label on the battery. We
recommend the use of an original
Vauxhall vehicle battery.

matching process should also be
performed after replacing a spare tyre with a road tyre containing the TPMS
sensor.
The malfunction light and the warning
message or code should go off at the
next ignition cycle. The sensors are
matched to the tyre/wheel positions,
using a TPMS relearn tool, in the
following order: left side front tyre,
right side front tyre, right side rear tyre and left side rear tyre. The turn signal
light at the current active position is
illuminated until sensor is matched.
Consult your workshop for service or
to purchase a relearn tool. There are
two minutes to match the first tyre/
wheel position, and five minutes
overall to match all four tyre/wheel
positions. If it takes longer, the
matching process stops and must be
restarted.The TPMS sensor matching process is:
1. Apply the parking brake; on vehicles with automatic
transmission set the selector lever
to P.
2. Turn the ignition on.
3. Use the MENU button on the turn
signal lever to select the Vehicle
Information Menu in the Driver
Information Centre (DIC).
4. Turn the adjuster wheel to scroll to
the tyre pressure menu.
5. Press the SET/CLR button to
begin the sensor matching
process. A message requesting
acceptance of the process should display.
6. Press the SET/CLR button again
to confirm the selection. The horn sounds twice to signal the
receiver is in relearn mode.
7. Start with the left side front tyre.
8. Place the relearn tool against the tyre sidewall, near the valve stem.
Then press the button to activate
the TPMS sensor. A horn chirpconfirms that the sensor
identification code has been
matched to this tyre and wheel
position.
