Driving tips
Driving tips
Improving fuel economy
The following tips will help you in improving fuel
economy.
–
A
void excessive idling.
–

A
void sudden acceleration.
–

A
void unnecessary deceleration and stopping.
–

Keep steady cruise speed as much as
possible.
Keep the air filter clean
If the air cleaner is clogged with dust, there
will be greater intake resistance, resulting in
decreased power output and increased fuel
consumption.
Keep tire pressures correct
Underinflating of the tires can waste fuel due to
increased running resistance of the tires. Keep
your tires inflated to the correct pressure shown
on the label on the driver’s door lock pillar.
Do not use tires other than those
specified by Citroën. Never use different
sizes or types of tires on the front and rear
wheels.
Driving on hills
When climbing steep hills, the vehicle may begin
to slow down and show a lack of power. If this
happens, you should shift to a lower gear so that
the engine will again be operating in its normal
power range
While driving down a hill, never turn off the
vehicle.
Try not to hold the brake pedal down too long
or too often while going down a long hill. This
could cause the brakes to overheat, resulting in
reduced braking efficiency.
Use the parking brake when parking your
vehicle and shift the gear shift lever into
the first gear or reverse gear position for the
sake of safety.
Driving on slippery roads
Under wet road conditions, you should drive at
a lower speed than on dry roads due to possible
slippage of tires during braking. When driving on
icy, snow-covered, or muddy roads, reduce your
speed and avoid sudden acceleration, abrupt
braking, or sharp steering movements.
Vehicle may break-down, meet with an
accident or catch fire due to:
–

Installation of:
•


High wattage bulbs
•


Non genuine lamps / horns
•


Modified suspension / wheels
•


Non genuine parts / accessories etc.
–


Short circuiting due to tampering of wiring
harness.
Do not store or carry inflammable
materials in the vehicle.
Avoid driving into or starting the vehicle in a heavily water logged area. Vehicle
may break-down or engine may fail due to:
–

W

ater entry into the engine.
–

Short circuiting of the electrical systems.
–


EV
AP (Evaporative Emission Control
System) malfunction.
If the vehicle is stuck into deep water, do not
start / crank the vehicle until the level of water
drops below the level of exhaust pipe.
If the vehicle is submerged in water, report to
the nearest authorized workshop.

verage Fuel Economy (AFE)
Definitions
Odometer
(km)
The total distance the vehicle has driven.
Trip meter A/B
(km)
The distance travelled in short trips or between
fuel stops.
Trips "A" and "B" are independent and are used
identically.
Average Fuel Economy (AFE)
(km/L)
The average fuel consumption calculated based
on the last trip.
Distance To Empty (DTE)
(km)
The distance which can still be travelled with the
fuel remaining in the tank (based on the current
driving conditions).
This value may vary following a change in
the style of driving or the terrain, resulting
in a significant change in the current fuel
consumption.
If dashes instead of figures continue to be
displayed when driving, contact a CITROËN
dealer.

Driving
6Only engage reverse gear when the
vehicle is stationary with the engine at
idle.
As a safety precaution and to facilitate starting the engine:
–

Always select neutral.
–


Press the clutch pedal.
Gear efficiency indicator
This system helps reduce fuel consumption by
recommending the most appropriate gear.
Operation
The system advises to change gear.The information appears in the instrument panel in the form of an ascending or
descending arrow.
The number displayed is the current gear.
Gear shift recommendations should not be
considered compulsory. In fact, the road layout,
the traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued by
the system.
This function cannot be deactivated.
The system adapts its gear shift recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (power, acceleration, braking,
etc.).
The system never suggests:
–

engaging first gear;
–


engaging reverse.
Overspeed alert
An audible overspeed alert is triggered when the
vehicle exceeds predefined speed thresholds.
When the vehicle speed is greater than 80 km/h,
the alert is emitted every 2 minutes.
When the vehicle speed is greater than 120
km/h, the alert is emitted every 2 seconds.
This system cannot be modified nor deactivated.
Parking sensors

Using sensors located in the bumper, this
system signals the proximity of obstacles
(e.g.
pedestrian, vehicle, tree, barrier) present in
their field of detection.
Rear parking sensors
The system is switched on by engaging reverse
gear.
The system is switched off when disengaging
reverse gear.
Audible assistance

The system signals the presence of obstacles
within the sensors’ detection zone.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle
and the obstacle becomes less than about
60
centimetres, the audible signal becomes
continuous.
Operating limits
If the boot is heavily loaded, the vehicle may tilt,
affecting distance measurements.

Practical information
The battery electrolyte must be filled. If the level
is found to be below the “MIN” level line, add
distilled water to the “MAX” level line.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Passenger compartment
filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine
oil is changed.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Brake pads
Brake wear depends on the style of
driving, particularly in the case of vehicles
used in town, over short distances. It may be
necessary to have the condition of the brakes
checked, even between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads
are worn.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc and drum wear
For information on checking brake disc
and drum wear, contact a CITROËN
dealer.
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 10
kilometres at over 50 km/h, add 0.3 bar (30 kPa)
to the values indicated on the label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause ABS and EBFD systems to mistime.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
the shock absorbers have a major impact on
road-holding and braking performance.
For your safety and driving comfort, it is
important to have them regularly checked by a
CITROËN dealer.
