ed video Fig. 219
Safety Description and operation
Traffic Jam Assist helps the driver keep the
car w
ithin its

lane and to move in convoy in
case of traffic congestion or slow traffic.
Traffic Jam Assist is an additional function of
Lane Assist ››› page 224 and combines Lane
Assist functions with Adaptive Cruise Control
(ACC) ››› page 214. Therefore, it is essential
that you read these two chapters carefully
and note the limitations of the systems and
the information about them.
Operation of Traffic Jam Assist
At speeds of below 60 km/h (40 mph), Traffic
Jam Assist can maintain a (temporary) dis-
tance preset by the driver with respect to the
vehicle ahead and help stay within the lane
››› .
T o do thi
s, the sy

stem automatically controls
the accelerator, brakes and steering, and
slows the vehicle, stopping it fully if neces-
sary, when faced with a vehicle in front that
has stopped. It automatically moves off again
when the vehicle ahead moves.
Traffic Jam Assist is designed only for use on
motorways and wide roads. Therefore, never
use it in city traffic. Technical requirements for using Traffic Jam

Checking and refilling levels
CAUTION
● Do not mi x
cleaning products recommen-
ded by SEAT with other products. This could
lead to flocculation and may block the wind-
screen washer jets.
● When topping up service fluids, make abso-
lutely c
ertain that you fill the fluids into the
correct reservoirs. Using the wrong fluids
could cause serious malfunctions and engine
damage!
● Not having windscreen wiper fluid reduces
vis
ibility through the windscreen, and leads
to loss of visibility in headlights in models
with headlight washer. Battery
