Parking the vehicle
When the vehicle is stopped, move the
lever to position P while keeping your
foot on the brake pedal: the gearbox is
in neutral and the drive wheels are me-
chanically locked by the driveshaft.
a pply the handbrake or, depending
on the vehicle, ensure that the elec-
tronic parking brake is applied.
Special circumstances
– If the road contours and bends
do not allow you to stay in auto -
matic mode (e.g.: in the mountains),
we recommend that you change to
manual mode.
This will prevent the automatic gear-
box from changing gears repeatedly
when climbing, and permit engine
braking on long descents.
– In cold weather , to prevent the
engine from stalling, wait a few mo-
ments before shifting the selector
lever from position P or N and en -
gaging D or R.
– Vehicles not fitted with traction
control: on a slippery surface or
surface with a low level of adhe -
sion, change to manual mode and
select second gear before starting
the engine to avoid wheelspin when
starting.
Driving in manual mode
With the selector lever in position D,
move the lever to the left. Shifting the
lever repeatedly allows you to change
gears manually:
– To move down through the gears,
push the lever backwards;
– To move up through the gears, push
the lever forwards.
The gear selected is displayed on the
instrument panel.
Special cases
Under certain driving conditions (e.g.
engine protection, electronic stability
program (ESP) operational etc.: ESC),
the “automatic system” may change
gear automatically.
Likewise, to prevent incorrect manoeu -
vres, a gear change may be refused by
the automatic system: in this case the
gear display flashes for a few seconds
as a warning.
aUtoMatIC GeaRBox (2/3)
An impact to the underside
of the vehicle (e.g.: striking
a post, raised kerb or other
street furniture) may result
in damage to the vehicle (e.g.: de -
formation of an axle).
To avoid any risk of accident, have
your vehicle checked by an ap -
proved Dealer.
In very cold weather, the system
may prevent the gears from being
shifted in manual mode until the
gearbox reaches the right tempera-
ture.

AuT oMATIc clIMATE coNTRol (2/4)
The displayed temperature values
show a comfort level.
When starting the engine, increas -
ing or decreasing the value dis -
played will not allow the com -
fort level to be reached any more
quickly. The system will always op-
timise the temperature increase or
decrease (the ventilation system
does not start instantly at maximum
speed: it gradually increases). This
may take several minutes.
Generally speaking, unless there is
a particular reason not to, the dash-
board air vents should remain open.
Switching air conditioning on
or off
In automatic mode, the system switches
the air conditioning system on or off,
depending on the climate conditions.
Press button 10 to switch off the air
conditioning.
Varying the ventilation speed
In automatic mode, the system uses
the most suitable amount of air to reach
and maintain the desired comfort level.
You can always adjust the ventilation
speed by pressing on the top or bottom
of button 11 to increase or decrease the
ventilation speed.
In this situation, the ventilation speed,
which is no longer automatically con -
trolled, appears on the display.
Where possible, it is recom -
mended that automatic mode is
used by selecting one of the auto-
matic programmes: AuT o, SoFT
or FAST.
In automatic mode (indicator light
for button 3 on), all heating and air
conditioning functions are controlled
by the system.
You can also change the system
selection, in this case, indicator
light for button 3 will go out and
the changed function, which is no
longer controlled by the system, is
shown on display 12.
To return to automatic mode, press
one of programmes: AuTo , S o FT
or FAST.

Air conditioning: information and advice on use
AIR coNDITIoNINg: information and advice on use
Fuel consumption
You will normally notice an increase
in fuel consumption (especially
when driving in town) when the air
conditioning is operating.
For vehicles fitted with manual air
conditioning, switch off the system
when it is not required.
Advice for reducing
consumption and therefore
helping to preserve the
environment:
Drive with the air vents open and
the windows closed.
If the vehicle has been parked in
the sun, open the doors for a few
moments to let the hot air escape
before starting the engine.
Maintenance
Refer to the Maintenance Document
for your vehicle for the inspection
frequency.operating faults
As a general rule, contact your ap-
proved Dealer in the event of an op-
erating fault:
– reduction in de-icing, demist -
ing or air conditioning per -
formance. This may be caused
by the passenger compartment
filter cartridge becoming clogged;
– no cold air is being produced.
Check that the controls are set
correctly and that the fuses are
sound. Otherwise, switch off the
system.
Advice on use
In some situations, (air conditioning
off, air recirculation activated, venti-
lation speed at zero or low, etc.) you
may notice that condensation starts
to form on the windows and wind -
screen.
If there is condensation, use the
“clear View” function to remove it,
then use the air conditioning in auto-
matic mode to stop it forming again.
If the condensation does not clear,
use the FAST programme.
Do not open the refriger -
ant fluid circuit. The fluid
may damage eyes or skin.
Note
Presence of water under the ve -
hicle. After prolonged use of the air
conditioning system, it is normal for
water to be present under the vehi-
cle. This is caused by condensation.

one-touch windows
The one-touch mode works in addition
to the operation of the electric windows
described previously.
– Fully press down (beyond the
notch) on the relevant switch: the
window will open completely.
– Fully lift (beyond the notch) the
relevant switch up: the window will
close completely.
Pressing the switch again while the
window is moving will stop its move -
ment.
Note: If the window detects resistance
when closing (e.g.: fingers, branch of
a tree, etc.) it stops and then lowers
again by a few centimetres.
These systems operate up to approxi -
mately 5 minutes after the engine is
switched off or until a door is opened.
If any part of the body be -
comes trapped, reverse the
direction of the window im -
mediately by pressing the
relevant switch.
Driver’s responsibility
Never leave your vehicle
with the RENAULT card
inside and never leave a
child (or a pet) unsupervised, even
for a short while.
They may pose a risk to themselves
or to others by starting the engine,
activating equipment such as the
electric windows or by locking the
doors.
Risk of serious injury.

Engine oil level:
general information
enGIne OIL LeVeL: general information (1/2)
Minimum oil level warning on
the instrument panel
When the message “test of functions
being checked” appears on the instru -
ment panel, press one of the buttons 3
or 4.
If the level is above the minimum
level : the display shows “oil level cor -
rect accompanied by squares 1 which,
when the level drops, are replaced by
dashes 2.
note: the detailed level cannot be dis-
played if the vehicle was previously
only driven for a short time. If the minimum level has been
reached: the message “Adjust oil level”
and warning light © lights up on
the instrument panel.
It is vital to top up the oil as soon as
possible.
n ote : To advance to trip computer
reading, press button 3 or 4 again.
The display only warns the
driver if the oil level is at the
minimum level. It does not
inform the driver that the oil
level has exceeded the maximum
level as this can only be measured
using a dipstick.
It is normal for an engine to use oil for
lubrication and cooling of moving parts
and it is normal to top up the level be-
tween oil changes.
However, contact your approved
Dealer if more than 0.5 litres is being
consumed every 600 miles (1,000 km)
after the running in period.
Oil change frequency: check the oil
level from time to time and certainly
before any long journey to avoid the
risk of damaging your engine.
Reading the oil level
The oil level should be read with the ve-
hicle on level ground, after the engine
has been switched off for some time.
t he dipstick must be used to read
the exact oil level and make sure
that the maximum level has not been
exceeded (risk of engine damage).
Refer to the following pages.
The instrument panel display only
alerts the driver when the oil level is at
its minimum.
