WARNING Risk of accident due toan
instrument clus ter malfunction
If th e instrument clus ter has failed or mal‐
functioned, you may not notice restrictions to
saf ety-re leva nt sy stem functions.
The operating saf ety of your vehicle may be
impaired. #
Drive on carefull y. #
Have theve hicle checked immediately
at a qualified specialist workshop. If
yo u are uncer tain rega rding the operational
saf ety of your vehicle, park theve hicle safely as
soon as possible. Inform a qualified specialist
wo rkshop.
The on-board computer will show only messages
and warnings from cer tain sy stems on the dis‐
pla y.Yo u should therefore make sure your vehicle
is operating safely at all times.

Speedome ter
In vehicles with Active Dis tance Assi st
DISTRONIC, there are illuminated segments on
th e speedome ter dial. These segments show
you what speed range is
av ailable:
R Variable limiter activated (/ page159)
The segments light up from thest art of the
scale tothe selected limit speed.
R Active Dis tance Assi stDISTRONIC switched
on (/ page 162)
One or two segments light up in the sa ved
speed range.
R Active Dis tance Assi stDISTRONIC de tects a
ve hicle in front.
The segments light up from the speed of the
ve hicle in front up tothe sa ved speed.
Yo u can show the speed as a digital speedome ter
on the display as well.
If yo uch ange your vehicle's wheel size, check its
assignment tothe wheel size group
(/ page 258). If the assignment changes with‐
out recoding the cont rol units in theve hicle, the
speedome ter will not display the speed accu‐
ra tely. The cur rent vehicle speed may then be
higher than the speed shown bythe speedome‐
te r.Driving and driving sa fety sy stems may then
be operationally impaired or may de tect a mal‐
function and switch themselves off.
In some count ries, an audible signal will sound
and/or a message will appear on the display
when theve hicle reaches the maximum speed
permitted bylaw, e.g. at 120 km/h.

R Recharge the battery more frequently in the
fo llowing cases:
- You predominantly drive short dis tances.
- You predominantly drive at low outside
te mp eratures.
- You lea vetheve hicle par kedfo r a lengt hy
period.
In order forth e batteries toachie vetheir max‐

be suf ficiently charge d.
R Consult a qualified specialist workshop if you
wish tolea veyour vehicle par ked up for a
long period of time.
R When you park theve hicle, remo vetheke y if
yo u do not require any elect rical consumers.
The vehicle will then use very little energy,
th us conserving bat tery powe r.
R Ifyo ur vehicle requ ires jump-s tarting, or if you
wish toprov ide jump-s tarting assis tance to
ano ther vehicle, only use the jump-s tart con‐
nection point in the engine compartment
(/ page 237).

Always allow a battery tothaw before
ch arging it or per form ing starting assis‐
ta nce. If

ch arge d battery has frozen. In
this case, obser vethefo llowing points:
R do not give theve hicle starting assis tance or
ch arge the battery
R the service life of a battery that has been
