Get Driving and Operation -> Catalytic converter, exhaust gases Guide for Vauxhall Meriva SUV First Generation (2003-2010)

Driving and Operation 145

Damage to the catalytic converter or the

vehicle may result if the following points

are not observed:

z If unburned fuel enters the catalytic

converter, this may result in overheating

and irreparable damage to the catalytic

converter.

z On ignition faults, uneven running after

cold start, a clear drop-off in engine

power or other unusual operating

symptoms which could indicate a fault in

the ignition system, contact a workshop

immediately. Continue driving if

necessary for a short time at low speed

and low revs.

You should therefore avoid

unnecessarily long use of the starter

when starting-off, running the tank dry

(an irregular fuel supply will lead to

overheating) and starting the engine by

pushing or towing.

Irregular engine running and a loss of

engine power when the Electronic

Stability Programme ESP®^Plus3 comes

into action are due to the operating

conditions and are therefore of no

significance - see page 149.

Catalytic converter, exhaust

gases

Catalytic converter for petrol engines

Leaded fuel will damage the catalytic

converter and parts of the elec tronic

system, rendering them inoperative.

Use of high-quality fuels other than those

specified on page 142 (e.g. LRP¹⁾) could

damage the catalytic converter.

1)

LRP = Lead Replacement Petrol.

Drivin g and Operation

z If the control indicator Z flashes to

indicate emissions, back off until the

flashing stops and the control indicator

illuminates. Contact a workshop

immediately. Control indicator for

emissions Z, see page 147.

Catalytic converter for diesel engines

Damage to the catalytic converter or the

vehicle may result if the following points

are not observed:

z On uneven running, a clear drop-off in

engine power or other unusualoperating

symptoms, contact a workshop

immediately. Continue driving if

necessary for a short time at low speed

and low revs.

Irregular engine running and a loss of

engine power when the Electronic

Stability Programme ESP®^Plus3 comes

into action are due to the operating

conditions and are therefore of no

significance - see page 149.

Controlling exhaust emission

Some of the damaging substances in the

exhaust such as carbon monoxide (CO),

hydrocarbons (HC) and nitrous oxides

(NO_x) are reduced to a minimum by

making structural changes – mainly in the

injection system and the ignition system in

conjunction with the catalytic converter.

Driving and Operation 147

Flashing with the engine running indicates

a fault which could lead to catalytic

converter damage. You may continue

driving without damage if you back off

until the flashing stops and the control

indicator illuminates steadily. Contact a

workshop immediately.

Control indicator Z for exhaust

Control indicator A for engine electronics

Illuminates when the ignition is switched on

and during the start attempt. Goes off

shortly after the engine starts running.

Illuminates for a few seconds after the

ignition is turned on.

If it illuminates when the engine is running,

there is a fault in engine or transmission

electronics. The electronic system switches

to an emergency runningprogramme. Fuel

consumption may be increased and the

driveability of the vehicle may be impaired.

Illuminated with the engine running

indicates a fault in the exhaust gas

cleaning system . The permitted em issions

may be exceeded . Contact a workshop

immediately.

In some cases, faults can be elim inated by

switching off the engine and restarting. If

the control indicator illuminates again

when the engine is running, contact a

workshop to eliminate the cause of the

fault.

148

Drivin g and Operation

If it illuminates briefly, but does not recur,

it is of no significance.

Exhaust gases

Under certain driving conditions, e.g. short

journeys, the sy stem may not clea n itself

automatically.

9 Warning

Illumination of control indicator A can

indicate water in the diesel fuel filter 3.

Check diesel fuel filter for possible water

residue, see page 230.

If control indicator ! flashes, drive on and

as soon as road and traffic conditions

allow, increase the speed to over 25 mph

(40 km/h) to start the diesel p article filter

cleaning. Cleaning is quickest at high

speeds and under load . The engine speed

should notfall below 2000 rpm. The control

indicator goes out as soon as cleaning is

complete.

Engine exhaust gases contain poisonous

carbon monoxide, which is colourless and

odourless and could be fatal if inhaled.

If itflashes after the ignition is switched on,

there is a fault in the immobiliser system.

The engine cannot be started –

see page 27.

If exhaust gases penetrate the vehicle

interior, open a window and contact a

workshop.

During the first drive, smoke may develop

because of wax and oilevaporating on the

exhaust system. Park the vehicle in the

open for a while after the first drive and

avoid inhaling the fumes.

We recommend not switching off the

ignition during cleaning.

Diesel particle filter 3

The diesel particle filter system filters

harmful soot particles out of the exhaust

gases.

The system contains a self-cleaning

function at set intervals. The filter is

cleaned by burning the soot particles at

high temperature. This process is

automatic in certain driving conditions and

can take up to 25 minutes. During this time,

fuel consumption may be increased. Some

od our a nd sm ok e are normal.
