DRIVING YOUR 406 COUPE127
CRUISE CONTROL Cruise control enables the vehicle to maintain a steady speed pro-
grammed by the driver, regardless ofthe road characteristics and withoutthe driver having to touch the accelerator or brake pedals. In order for it to be memorised, the vehicle speed must be greater than25 mph (40 km/h) or 37 mph (60 km/h), depending on the engine,and fourth gear at least must beengaged (second gear for the auto-matic gearbox). Operation ☞
Place switch 1in the ONposition.
A speed can be memorised.
☞ Place switch 1in the OFF position
to cancel.
Memorising a speedAs soon as you reach the chosen speed, press button 2or 3. This
memorises the speed, which will be
maintained automatically. Note:
It is possible to accelerate and drive
momentarily at a speed greater than the memorised speed. When the acceleratorpedal is released, the vehicle will return tothe memorised speed. Cancelling the memorised speed If you wish to cancel the memorised speed: ☞ Press button 4or the brake or
clutch pedal.
Recalling the memorised speedAfter cancellation, press button 4.
Y our vehicle will return to the last
memorised speed. Changing a memorised speed
To memorise a speed higher than
the previous one: ☞ press button 3;
☞ release it when you have reached the required speed.
To memorise a speed lower than the
previous one: ☞ press button 2;
☞ release it when you have reached the required speed.
Cancelling the cruise control ☞ place switch 1in the OFF position
or switch off the ignition.
Do not use cruise control on slippery roads or inheavy traffic. THE ABS ANTI-LOCK BRAKINGSYSTEM
When used with approved tyres in
good condition, the ABS increasesthe stability and manoeuvrability ofyour vehicle, particularly on poor orslippery road surfaces. The anti-lock braking system comes into operation automatically whenthere is a risk of wheel lock.
EMERGENCY BRAKING
ASSISTANCE SYSTEM
In an emergency, this system enables the optimum braking pres-
sure to be reached more quickly,thus reducing the stopping distance. It is triggered by the speed at which
the brake pedal is activated. The
effect of this is a reduction in theresistance of the pedal and an
increase in braking efficiency. The normal operation of the ABSmay make itself felt by slightvibrations of the brake pedal. In emergency braking, press very firmly without releasingthe pressure.

CHECKING THE LEVELS Oil level Check the level regularly and top up between changes. Maximumconsumption is 0.5 litres per 600miles (1 000 km). The oil level should be checked with the vehicle level and the engine coldusing the oil gauge or the dipstick.Dipstick There are two marks on the dipstick: A= maximum
Never fill past this mark. B = minimum
To maintain the reliability
of the engines and of the emission control sys-tems, the use of additivesin the engine oil is prohi-bited.
Oil change According to the indications of the
"PEUGEOT SERVICES" .
Note: avoid any prolonged contact of
used oil with the skin. V iscosity selection
In all cases, the oil selected must meet the manufacturer's require-ments.

Brakes and clutch level: -The level should always be bet- ween the DANGER and MAX
marks on the reservoir.
- If the level drops substantially,
contact a PEUGEOT dealer imme-
diately.
Fluid change - must be carried out according to the manufacturer's servicing sche-dule.
- use fluids recommended by the
manufacturer, which fulfil DOT 4standards.
Note: the brake fluid is noxious and
very corrosive. Avoid any contactwith the skin. Coolant level Use the fluid recommended by the
manufacturer. When the engine is warm, the tem- perature of the coolant is controlledby the engine fan. Because this fan
can operate with the ignition off andbecause the cooling system is pres-surised, wait for at least one hourafter the engine has stopped beforecarrying out any work.
To avoid any risk of burns, slacken
the cap to the first notch to release the pressure. When the pressure hasdropped, remove the cap and top upthe level. Used products Do not dispose of used oil, brake fluid or coolant down drains or on theground. Power steering fluid level Open the reservoir with the engine cold. The level should always beabove the MINI mark, close to theMAXI mark. W

BATTERY
To
charge the battery using a battery charger:
- Disconnect the battery,
- Follow the instructions for use given by the battery charger manufacturer,
- Reconnect starting with the negative (-) terminal,
- Check that the terminals and connectors are clean. If they are covered with sul- phate (white or greenish deposit), disconnect them and clean them.
To start the vehicle from another battery:
- Connect the red cable to the positive (+) terminals of the two batteries,
- Connect one end of the green or black cable to the negative (-) terminal of the
slave battery,
- Connect the other end of the green or black cable to an earth point on the bro-
ken down vehicle, as far as possible from the battery,
Operate the starter, let the engine run. W ait for the engine to return to idle, then disconnect the cables.
-Never disconnect a terminal when the engine is running.
- Never charge a battery without first disconnecting the terminals.
- Close the sunroof before disconnecting the battery. If it does not opera-
te normally following re-connection of the battery, you must re-initialise it by turning the control to the maximum tilt position and pressing it for a fewseconds.
- After every reconnection of the battery, switch on the ignition and wait 1minute before starting to allow the electronic systems to be initialised. If slight
difficulties are experienced after this, please contact a PEUGEOT dealer.
It is advisable to disconnect the battery if the vehicle is not to be used
for a period of more than one month.
Economy mode
With the engine switched off and the ignition key in the "running" or"accessories" position for about half
an hour, certain electrical equipment(displays, instrument panel, warninglights, courtesy lights, electric win-
dows, wipers etc.) will switch offautomatically to avoid draining the
battery. Once the electrical equipment goes into economy mode, it is necessaryto start the engine to enable theequipment to work again.
