My manual for some reason doesn't show a 1.3 Doblo. On the 1.9 Doblo I read this as parallel to 20 minutes toe out as max. tolerance, with ideal 10min. toe out when using a wheel alignment gauge.
This makes sense to me as generally front wheel drive vehicles pull the wheels in and rear wheel drive vehicles push them apart.
Perhaps another Forum member has exact data for your 1.3
