Then updte-grub afterwords.
But do not change the resume line, otherwise you may not be able to boot.

Quote:'GRUB_TIMEOUT'
Boot the default entry this many seconds after the menu is
displayed, unless a key is pressed. The default is '5'. Set to
'0' to boot immediately without displaying the menu, or to '-1' to
wait indefinitely.

If 'GRUB_TIMEOUT_STYLE' is set to 'countdown' or 'hidden', the
timeout is instead counted before the menu is displayed.

'GRUB_TIMEOUT_STYLE'
If this option is unset or set to 'menu', then GRUB will display
the menu and then wait for the timeout set by 'GRUB_TIMEOUT' to
expire before booting the default entry. Pressing a key interrupts
the timeout.

If this option is set to 'countdown' or 'hidden', then, before
displaying the menu, GRUB will wait for the timeout set by
'GRUB_TIMEOUT' to expire. If <ESC> is pressed during that time, it
will display the menu and wait for input. If a hotkey associated
with a menu entry is pressed, it will boot the associated menu
entry immediately. If the timeout expires before either of these
happens, it will boot the default entry. In the 'countdown' case,
it will show a one-line indication of the remaining time.

This is actually an old issue as GRUB_HIDDEN_TIMEOUT and GRUB_HIDDEN_TIMEOUT_QUIET have been deprecated in grub for some time now (approx. 2013). These have been replaced with GRUB_TIMEOUT_STYLE.

Type the following into a terminal to get grubs options:

Code:

info -f grub -n 'Simple configuration'

Quote:'GRUB_TIMEOUT'
    Boot the default entry this many seconds after the menu is

    If 'GRUB_TIMEOUT_STYLE' is set to 'countdown' or 'hidden', the

So basically this is what should be set to get your desired effect:

Code:

GRUB_THEME=/boot/grub/themes/maui/theme.txt
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=40fcaab4-82a8-4915-99e8-7d6f2e322d73"
GRUB_DISTRIBUTOR="Maui"

GRUB_DEFAULT=0
GRUB_TIMEOUT=90
GRUB_TIMEOUT_STYLE=hidden
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

I re-installed Win7 and freshly installed Maui 2.1 "Blue Tang" (dual boot) and updated/upgraded Maui OS; Build Version:20161117.

KDE Plasma Version: 5.8.3
KDE Apps Version: 16.08.2
Framework Version: 5.27.0
Qt Version: 5.7.0
Kernel Version: 4.4.0-57 generic

According to '/etc/default/grub.ufc-dist' the GRUB_TIMEOUT is originally set to 10 seconds but booting already begins after 3 seconds. I edited my desired boot time to 90 seconds, updated grub, but the '3sec boot time' persists.  
Below is shown my most recent edit of grub.ucf-dist:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=90
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

I can't find a suitable KDE package in Synaptic PM.
I request assistance to manually enable boot time to 90 seconds without installing additional software such as 'Grub Customizer'.
