Switching off the ignition
To switch off the ignition, the vehicle must be
stationary.
Changing to free-wheeling
For more information on Changing to free-
wheeling , refer to the corresponding section.
If you open the driver's door while mode
N is engaged, an audible signal will
sound. It will stop when you close the driver's
door again.
Special aspects of automatic mode
The gearbox selects the gear that offers
optimum performance, taking account of the
outside temperature, the road profile, the vehicle
load and the driving style.
For maximum acceleration, press the accelerator
fully down (kick-down). The gearbox changes
down automatically or holds the selected gear
until the maximum engine speed is reached.
Steering mounted controls allow the driver to
temporarily select a gear, if the vehicle speed
and engine speed conditions permit.
Special aspects of manual mode
The gearbox only changes from one gear to
another if the vehicle speed and engine speed
conditions permit.
Starting the vehicle
From mode P:
►
Fully depress the brake pedal.
►

Start the engine.
►


Maintaining pressure on the brake pedal,
press the

Unlock button.
►

Push once or twice rearwards to select
the automatic mode

D, or forwards to engage
reverse
R.
From neutral
N:
►

Fully depress the brake pedal.
► Start the engine.
► Maintaining pressure on the brake pedal,
push rearwards to select the automatic mode D,
or forwards, while pressing the Unlock button to
engage reverse R.
Then, from D or R:
► Release the brake pedal.
► Accelerate gradually to automatically release
the electric parking brake.
The vehicle moves off immediately.
With an automatic gearbox, never try to
start the engine by pushing the vehicle.
Stopping the vehicle
Whatever the state of the gearbox, when the
ignition is switched off, mode P is engaged
automatically and immediately.
However, in mode N, mode P will be engaged
after a delay of 5 seconds (allowing for the
process of putting the vehicle into free-wheeling
mode).
Check that mode P has been engaged and
that the electric parking brake was applied
automatically; if not, apply it manually.
The corresponding indicator lamps in the selector and the electric parking brake
control lever must be on, as well as those in the
instrument panel.

Driving
control being paused will also cause the
system to be paused.
If the system detects that the driver is not
holding the wheel firmly enough, it
triggers a series of gradual alerts and then
deactivates itself if there is no response from
the driver.
If the function is suspended due to the
prolonged release of the force holding
the steering wheel, you must reactivate it by
pressing the button again.
Automatic pause
– Triggering of the ESC.
– Prolonged failure to detect one of the lane limit
markings. In this case, the active lane departure
warning function can take over
, and the system
will reactivate itself once the operating conditions
are again met.
In response to action by the driver:
suspension
– Activation of the direction indicators.
– T ravelling outside the lane limits.
–

T
oo tight a grip on the steering wheel or
dynamic action on the steering wheel.
–

Action on the brake pedal (resulting in a pause
until cruise control is reactivated) or accelerator
pedal (suspension for as long as the pedal is
depressed).
–


Pausing of the cruise control.
–


Deactivation of the
ASR.

The Diesel fuel system operates under
very high pressure.
All work on this circuit must be carried out
only by a PEUGEOT dealer or a qualified
workshop.
* Depending on engine.
Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a PEUGEOT
dealer or a qualified workshop.
The fluids must comply with the manufacturer's requirements and with
the vehicle's engine.
Take care when working under the bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and the
cooling fan could start at any time (even with
the ignition off).
Used products
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a PEUGEOT dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
►

Grasp the dipstick by its coloured grip and
pull it out completely

.
►

Wipe the end of the dipstick using a clean,
lint-free cloth.


► Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil
level: the correct level is between marks A (max)
and B (min).
Do not start the engine if the level is:
– above mark A: contact a PEUGEOT dealer or
a qualified workshop.
– below mark B: top up the engine oil
immediately.
Oil grade
Before topping up or changing the engine
oil, check that the oil is suitable for the engine
and complies with the recommendations in
the service schedule supplied with the vehicle
(or available from your PEUGEOT dealer and
qualified workshops).
Use of non-recommended oil may invalidate
the contractual warranty in the event of
engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding under-bonnet engine
compartment illustration.

For the location of the engine oil filler cap, please
refer to the corresponding under-bonnet engine
compartment illustration.
► Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►

W
ait a few minutes before checking the level
again using the dipstick.
►

T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
Within 30 minutes of adding oil, the oil
level indication in the instrument panel
when the ignition is switched on is not valid.
Brake fluid
The level of this fluid should be close to the "MAX" mark. If not, check the brake
pad wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A low level presents a risk of serious damage to
the engine.
The level of this fluid should be close to the
"MAX" mark but should never exceed it.
If the level is close to or below the " MIN” mark, it
is essential to top up.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
