Specifi cation of the fl uid
To ensure optimum cleaning and to avoid freezing, the fluid should never be topped up or replaced by plain water.
According to your version of instrument panel, the additive reser voir low level is indicated by:
- fixed illumination of the particle emissions filter warning lamp, accompanied by an audible signal and a message that the particle emissions filter additive level is too low,
or
- fixed illumination of the ser vice warning lamp, accompanied by

243Practical information
Changing a wheel
Procedure for changing a faulty wheel for the spare w heel using the tools provided with the vehicle.
The tools are installed in the boot under the floor. To gain access to them:  open the boot,  raise the floor,  secure it by hooking its cord on the hook on the rear shelf suppor t,  with a standard size spare wheel, unclip and remove the box in the middle of the wheel containing the tools,
or  with a "space-saver" spare wheel; lift the wheel at the rear towards you for access to the storage box containing the tools.
Access to the tools
List of tools
All of these tools are specific to your vehicle. Do not use them for other purposes.
Wheel with trim
When removing the wheel , detach the trim first using the wheelbrace 1 pulling at the valve passage hole. When refitting the wheel , refit the trim star ting by placing its notch facing the valve and press around its edge with the palm of your hand.
3. "Bolt cover" tool.
For removing the bolt protectors (covers) on alloy wheels. 4. Socket for the security bolts (located in the glove box).
For adapting the wheelbrace to the special "security" bolts.
1. Wheelbrace.
For removing the wheel trim and the wheel fixing bolts. 2. Jack with integral handle. For raising the vehicle.

Removing a wheel
Parking the vehicle
Immobilise the vehicle where it does not block traffic: the ground must be level, stable and non-slippery ground. Apply the parking brake unless it has been programmed to automatic mode, switch off the ignition and engage first gear * to lock the wheels. Check that the braking warning lamps in the instrument panel are on (not flashing). If necessary, place a chock under the wheel diagonally opposite the wheel to be changed. The occupants must get out of the vehicle and wait where they are safe. Never go underneath a vehicle raised using a jack; use an axle stand.
List of operations
 Remove the chromed bolt cover from each of the bolts using the tool 3 (according to
equipment).  Fit the security socket 4 on the wheelbrace 1 to slacken the security bolt.
 Slacken the other bolts using the wheelbrace 1 only.
* position R for the electronic gearbox system.

Fitting a steel or "space-saver" spare wheel
If your vehicle is fitted with alloy wheels, when tightening the bolts on fitting it is normal to notice that the
washers do not come into contact with the steel or "space-saver" spare wheel. The wheel is secured by the conical contact of each bolt.
List of operations
 Put the wheel in place on the hub.  Screw in the bolts by hand to the stop.
 Pre-tighten the security bolt using the wheelbrace 1 fitted with the security socket 4 .  Pre-tighten the other bolts using the wheelbrace 1 only.
After changing a wheel
To store the punctured wheel in the boot correctly, first remove the central cover. When using the "space-saver" type spare wheel, do not exceed 50 mph (80 km/h). Have the tightening of the bolts and the pressure of the spare wheel checked by a CITROËN dealer or a qualified workshop without delay. Have the punctured wheel repaired and replace it on the vehicle as soon as possible.

249Practical information
 Lower the vehicle fully.  Fold the jack 2 and detach it.  Tighten the security bolt using the wheelbrace 1 fitted with the security socket 4 . Tighten the other bolts using the wheelbrace 1 only.  Refit the chromed bolt covers on each of
the bolts (according to equipment).  Store the tools in the box.
