Britax ISOFIX Leaflet

The Hampshire Trading Standards Authority and Britax advise 

that child car seats should not be bought or sold second-hand. 

Please dispose of your child seat safely. Do not sell or pass it on.
After an accident, the child seat and your vehicle  seat belts 

should be replaced. Although they may look undamaged, if you 

were to have another accident the child seat and your vehicle 

seat belts may not be able to protect your child as well as they 

should.
No child seat is escape proof 

Harness systems cannot be designed to be completely “child 

proof” and yet comply with the legal requirements of European 

Standard ECE R44. The harness must be fastened and adjusted 

correctly at all times and children encouraged to remain within 

the harness system.
Looking after your child seat

 

Food and drink may find their way inside the buckle of the 

harness. This can stop it from working properly – it will not click. 

Wash in warm water until clean 

(dia A and B).

Cleaning the cover 

Please read the labels on the cover for washing instructions. 
DO NOT tumble dry the cover – short spin and drip dry only.
Cleaning the seat shell 

Sponge clean 

ONLY using hand soap and warm water.

DO NOT take apart, or attempt to take apart, any part of the seat 

when cleaning. 
DO NOT use solvents, detergents or washing-up liquid as these 

may weaken the seat. 
DO NOT lubricate or oil any part of the seat.

Removing the cover  

Press in and hold the adjuster button with your hand below the 

chest pads 

(dia 1a) pull BOTH shoulder straps forward as far 

as possible. Unfasten the buckle by pressing the red harness 

buckle button 

(dia 1c). Undo the press studs from around the 

harness straps on either side of the headrest cover, tilt the 

headrest forward and lift off the headrest cover. Undo the press 

studs on the backrest cover, push the harness buckle and 

adjuster strap through the cover, unhook the elastic seam of the 

cover from under the edge of the seat shell and gently lift the 

backrest cover off the shell. 
Re-fitting the cover 

Simply proceed in the reverse order. 

 The cover is a safety feature. 

NEVER use the child 

seat without it. Don’t put your child’s safety at risk by using other 

makes of replacement cover, they could stop the child seat from 

protecting your child as well as it should.
A replacement cover is available from your Britax stockist or 

contact Britax Customer Service Department on 

01264  386034.

 use the child seat on a passenger seat fitted with an 

active front airbag unless your vehicle manufacturer confirms 

that it is safe.

 use the child seat on rearward facing seats.

 use the child seat on side facing vehicle seats.

 use anything, such as a cushion or coat, to raise the child 

seat off the passenger seat. In an accident the child seat and your 

vehicle seat belts would not be able to protect your child as well as 

they should.

 use the child seat in the home. It has not been 

designed for home use and should only be used in your vehicle.

 attempt to dismantle, modify or add to any part of the 

child seat or change the way its harness or your vehicle seat 

belts are made or used. The official approval is no longer valid if 

modifications are made. 

NO modifications may be made to the 

child seat other than by the manufacturer.

 leave children alone in your car, even for a short time.

 leave loose objects, such as luggage or books, in the 

back of your vehicle. They must be properly secured, because 

if you have to stop your vehicle suddenly loose objects will keep 

moving and can then cause serious injuries. Large and heavy 

loose objects are a particular risk. 

 leave folding passenger seats unlatched. If you have to 

stop your vehicle suddenly a loose seat back could injure your 

child.

 allow children to play with or adjust the child seat.

 keep this user guide in the user guide storage slot.

 cover the child seat if your car is left in direct sunlight. 

Fittings can become hot to touch in sunny weather and the cover 

may become faded.

 make sure that the child seat does not become trapped by a 

folding passenger seat or in the door of your car.

 make sure that you adjust the harness to fit the clothes your 

child is wearing before each journey – a fitting for winter clothes 

may be too slack for a child wearing summer clothes.

 store the child seat in a safe place when it is not being used. 

Avoid placing heavy objects on top of it and do not store near 

direct heat sources or in direct sunlight.

 always keep the child seat secure, even if it is not being used 

by your child.

 make sure that all occupants in the vehicle are correctly 

restrained.

 where necessary, use the insertion guides when installing 

the child seat with ISOFIX fittings. Failure to do so may result in 

damage to your vehicle seat.

 make sure that your child seat is firmly latched to its 

anchorage points.
