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.

Safety
5General safety
recommendations
Do not remove the labels attached in
different places on your vehicle. They
include safety warnings as well as
identification information for the vehicle.
For all work on your vehicle, use a
qualified workshop that has the technical
information, skills and equipment required, all
of which a CITROËN dealer is able to
provide.
Installing electrical accessories:
– The fitting of electrical equipment
or accessories not approved by CITROËN
may cause excessive current consumption
and failure of the vehicle's electrical system.
Contact a CITROËN dealer for information on
the range of approved accessories.
–

As a safety measure, access to the
diagnostic socket, used for the vehicle's
electronic systems, is reserved strictly for
CITROËN dealers, equipped with the special
tools required (risk of malfunctions of the
vehicle's electronic systems that could cause
breakdowns or serious accidents).

The
Manufacturer cannot be held responsible if
this advice is not followed.
–

Any modification or adaptation not intended
or authorised by CITROËN or carried out
without meeting the technical requirements
defined by the Manufacturer will result in the
suspension of the commercial warranty.
Hazard warning lamps



► Pressing the red button causes all the
direction indicators to flash.
They can operate with the ignition off.
Horn

► Press the central part of the steering wheel.
Anti-lock Braking System (ABS) and Electronic
Brake Force Distribution
(EBFD)
These systems enhance the vehicle’s stability
and handling during braking, and enable greater
control while cornering, particularly on poor or
slippery road surfaces.
ABS prevents wheel locking in the event of
emergency braking.
EBFD manages the braking pressure wheel by
wheel.
This warning lamp is continuously on in
the event of an ABS malfunction.
The vehicle retains conventional braking. Drive
carefully at a moderate speed.
Contact a CITROËN dealer as soon as possible.
This warning lamp, accompanied by an audible signal, indicates an EBFD
malfunction.
You must stop as soon as it is safe to do so.
Contact a CITROËN dealer.
The normal operation of the ABS may result in slight vibrations in the brake
pedal.
When braking in an emergency, press
the brake pedal very firmly and
maintain this pressure.
