Electronic speed Limiter
Your v ehicle may be factory equipped with tires
that are rated for a maximum speed of 130 mph (210 km/h). This is less than the maximum sp eed
of your vehicle . To reduce the risk of sudden tire
failure and loss of control if the vehicle is operat ed at excessive speeds, your vehicle also has an
electronic speed limiter . The electronic speed
lim iter prevents your vehicle from going faster
than the t ire speed rating. For mo re information
<=> page 333.
If the engine control unit receives faulty vehicle
road speed s ignals , the Malfunction Indicator
L amp (MIL)
¢..ffi will illumina te . If this occurs,
con tact the nearest au thorized A ud i dealer for
assistance.
_& WARNING
Always observe the posted speed limits and
adjust you r speed to suit prevailing road, traf
fic and weather conditions. Never drive your
vehicle faster than the maximum speed rating
of the tires installed .
Speed warning system
Introduction
Applies to: vehicles with speed warning system
The speed warning system helps you to stay be
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system.
-
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
A wa rning tone will sound as soon as you r speed
ex ceeds the s tored v alue s light ly. Th e indicato r
light also turns on in the instrument cluster dis
p lay
ct] (USA models)/ [SJ (Canada models) and
a message . The indicator light
(CJ / [SJ and the
message turn off if the speed falls back be low
the stored maximum speed.
Se tting a threshold is recommended if you would
like to be reminded when yo u reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gene r-
102
al speed limit or if there is a spec ified maximum
speed for winter tires.

Camera-based traffic

F ig. 98 Windsh ield: came ra window for t raffic s ig n recog
ni tio n
Traff ic sign recognition assists you when driving
by displaying detected speed limits or s igns pro
hibiting passing in the instrument cluster display
c:;, fig . 97 . Within the limits of the system, the le
gal speed lim its in school zones are detected and
disp layed .
General information
Traffic sign recognit ion can detect standard
speed limit signs that are within the camera's vis
ual field . With ass istance from navigation data,
104
detected speed limits are evaluated and shown in
the display . The traffic sign for the current de
tected speed lim it will blink in the display if you
exceed the warning thresho ld set in the Infotain
ment system
c;, page 105.
The traffic sign recognition is subject to certain
system limitations and may be unavai lable or on
ly partially avai lable in the follow ing situations :
- when visibility is poor, such as in snow, rain,
fog or heavy spray
-when there is glare, for example from oncom
ing traffic or the sun
- at high speeds
- if the camera's visual field
¢ fig. 98 is covered,
for examp le by dirt or st ickers. For info rmation
on cleaning, see
¢page 354 .
-if the tra ffic signs are completely or partially
covered, for examp le by trees, snow, dirt or
other vehicles
- if speed traffic signs do not conform to the
standards
- if traffic signs are damaged or bent
- if traffic signs are displayed on sign holders
w ith electronic signs
- if the traffic signs or the configuration of the
road have changed (navigation data is no lon
ger up-to-date)
.&_ WARNING
Pay attention to traffic and the area around
your vehicle when traffic sign recognition is
turned on . The traffic signs insta lled on the
road always take precedence over the display.
The driver is always responsible for assess ing
the traffic situation.
- Under some circumstances, traffic sign rec
ognition may not detect traffic signs cor
rectly or detect them at a ll. As a result, the
system may not display the correct speed
lim it or any speed limit .
- Traff ic sign recognit ion does not adapt your
veh icle's speed to match the speed limit!

General information
The predictive control 1l uses the map informa
tion from the navigation system in order to react
proact ively when driv ing. Information from the
camera-based traffic sign recognition* is also ap plied to recognize traffic signs
<:!)page 104.
When coming up to areas with speed limits or
changes in the course of the road (such as curves,
intersections or traffic circles), the system brakes
automatically and then accelerates back up to
the set speed .
When adaptive cruise control is switched off, the
system only provides notifications without con
trolled interventions ¢
page 105.
The driver can override the predictive control at
any time by pressing the accelerator or brake
pedal. If the system changes the vehicle speed to
adapt to speed limits, you can change the speed
using the lever
¢ page 110, fig. 106 .
Always switch off the predictive control in
the following situations:
- When increased attention is needed from the
driver .
- In poor weather conditions such as snow or
heavy rain.
- When driving on roads in poor condition .
