Energy economy modeSystem which manages the period of use of certain functions to conserve a sufficient level of charge in the battery.
A fter   the   engine   has   stopped,   you   can   still   use   functions   such   as   the   audio   equipment,   windscreen   wipers,   dipped   beam   headlamps,   courtesy   lamps,  
e

tc.   for   a   maximum   combined   period   of   thirty   minutes.
This
  period   may   be   greatly   reduced   if  
t

Observe the legislation in force in your country.
E nsure   that   the   weight   of   the   towing   vehicle   is   higher   than   that   of   the   towed   vehicle.
The
  driver   must   remain   at   the   wheel   of   the   towed   vehicle   and   must   have   a   valid   driving   licence.
When
  towing   a   vehicle   with   all   four   wheels   on   the   ground,   always   use   an   approved   towing  
a

rm;   rope   and   straps   are   prohibited.
The
  towing   vehicle   must   move   off   gently.
When

Towing a trailer
Towbar suitable for the attachment of a trailer with a dditional l ighting an d s ignalling. We
  recommend   the   use   of   genuine  
C

ITR
oË
N towbars and their harnesses
that have been tested and approved
from   the   design   stage   of   your   vehicle,  
a

nd   that   the   fitting   of   the   towbar   is  
e

ntrusted to a CITR
oË
N dealer or a
qualified
 w
orkshop.
If the towbar is not fitted by a CITR
oË
N
dealer,   it   is   imperative   that   it   is  
f

itted in accordance with the vehicle
manufacturer's
 i
nstructions.
Driving   with   a   trailer   places   greater   demands  
o

n   the   towing   vehicle   and   the   driver   must   take

driving advice
distribution of loads
F Distribute the load in the trailer so that the heaviest   items   are   as   close   as   possible   to t

he   axle   and   the   nose   weight   approaches   the
 m

aximum   permitted   without   exceeding   it.
ai

r density decreases with altitude, thus
reducing
  engine   per formance.   Above  
1

  000   metres,   the   maximum   towed   load   must  
b

e   reduced   by   10   %   for   every   1   000   metres   of  
al

titude.
Side wind

RAcING towbar
Your vehicle cannot be fitted with a
towbar.  The   space   occupied   by   the  
s

port   diffuser   prevents   this.
Ty r e s
F Check  the   tyre   pressures   of   the   towing  v
ehicle   and   of   the   trailer,   observing   the  
re

commended
 p
ressures.
cooling
Towing a trailer on a slope increases the temperature   of   the   coolant.
As
  the   fan   is   electrically   controlled,   its   cooling  
c

apacity   is   not   dependent   on   the   engine   speed.
F
 
T
o   lower   the   engine   speed,   reduce   your  
s

peed.
The
  maximum   towed   load   on   a   long   incline  
d

epends   on   the   gradient   and   the   ambient  
t

emperature.
In
  all   cases,   keep   a   check   on   the   coolant  
t

emperature.
Braking
Towing a trailer increases the braking distance.
T o   avoid   overheating   of   the   brakes   on   a   long  
m

ountain   type   of   descent,   the   use   of   engine  
b

raking   is   recommended.
Lighting
F Check   the   electrical   lighting   and   signalling  o
