2021 MERCEDES-BENZ GLA SUV battery

St
andby mode is characterised bythefo llowing:
R The star ter battery is preser ved.
R The maximum non-operational time appears in
th e media displa y.
R The connection toonline services is inter rup-
te d.
R The ATA (anti-theT alarm system) is not availa-
ble.
R The interior pr otection and tow- aw ay protec-
tion functions are not available.

par kedve hicle is not available.
If th efo llowing conditions are ful/lled, standby
mode can be activated or deactivated using the
multimedia system:
R The vehicle is switched on.
R The vehicle has not been star ted.
Exceeding theve hicle's displ ayed non-operational
time may cause incon venience; i.e. it cannot be
guaranteed that the star ter battery will reliably
start theve hicle. Char
gethe star ter battery in thefo llowing situa-
tions:
R The vehicle's non-ope rational time must be
ex tended.
R The Battery charge insufficient for standby
mode messa geappears in the media displa y.

th th e Mercedes-Benz emer gency call system
as well as the 112 emer gency call system (EU
eCall) can help toreduce the time between an
accident and the ar riva l of emer gency services at
th e site of the accident. They help locate an acci-
dent site in places that are di1cult toaccess. Bo
th emer gency call systems can initia tean emer-
ge ncy call automatically (/ page 330) or man-
ual ly ( / page 331).
Only make emer gency calls if you or others are in
need of rescue. Do not make an emer gency call in
th eev ent of a breakdown or a similar situation.
