2010 CITROEN DS4 overheating

95
With the engine running, the front seats can be
heated separately.
Heated seats control
Do not use the function if the seat is not
occupied.
Reduce the level of heating as soon as
possible.
Once the seat and passenger
compartment are at a comfortable
temperature, you can switch off the
function; reducing electric current
consumption also reduces fuel
consumption.Prolonged use at the highest setting
is not recommended for those with
sensitive skin.
There is a risk of burns for those that
do not have normal perception of heat
(illness, taking medicines,
...).
There is a risk of overheating the
system if material with insulating
properties is used, such as cushions or
seat covers.
Do not use the system:
-

i
f wearing damp clothing,
-

i
f child seats are fitted.
To avoid breaking the heating element
in the seat:
-

d
o not place heavy objects on the
seat,
-

d
o not kneel or stand on the seat,
-

d
o not place sharp objects on the
seat,
-

d
o not spill liquids onto the seat.
To avoid the risk of short-circuit:
-

d
o not use liquid products for
cleaning the seat,
-

n
ever use the heating function
when the seat is damp.

Driving recommendations
Observe the driving regulations and remain vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your hands on the wheel so that you are ready to react at
any time to any eventuality.
As a safety precaution, the driver must only carry out actions requiring sustained attention when
the vehicle is stationary.
On a long journey, a break every two hours is strongly recommended.
In difficult weather, drive smoothly, anticipate the need to brake and increase the distance from
other vehicles.Never drive with the parking brake
applied - Risk of overheating and
damage to the braking system!
Risk of fire!
As the exhaust system of your vehicle
is very hot, even several minutes
after switching off the engine, do not
park or leave the engine running over
areas where inflammable substances
and materials are present: grass,
leaves,
etc.
Never leave a vehicle unsupervised
with the engine running. If you have
to leave your vehicle with the engine
running, apply the parking brake
and put the gearbox into neutral or
position


N or P, depending on the type
of gearbox.
Driving on flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage
to the engine or gearbox, as well as to the
electrical systems of your vehicle.
Important!
- check that the depth of water does not exceed 15 cm, taking account of waves
that might be generated by other users,
-

d
eactivate the Stop & Start system,
-

d
rive as slowly as possible without
stalling. In all cases, do not exceed 6 mph
(10
km/h),
-

d
o not stop and do not switch off the
engine.
If you are obliged to drive through water:
On leaving the flooded road, as soon as
circumstances allow, make several light brake
applications to dry the brake discs and pads.
If in doubt on the state of your vehicle, contact
a CITROËN dealer or a qualified workshop.

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without exceeding
it.
Air density decreases with altitude, thus
reducing engine per formance. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
Side wind
F Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine
as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam
height of your vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding section.
For more information on Weights
, refer
to the corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
If the exterior temperature is high, it
is recommended that the engine be
allowed to idle for 1 to 2 minutes after
the vehicle comes to a stop, to facilitate
its cooling.
