Off-roader?

Description and operation

Driver assistance systems

If your SEAT vehicle is not an off-roader: it

does not have enough ground clearance to

be used as such. It is therefore best to avoid

rough tracks and uneven terrain as much as

possible.

The Start-Stop system helps save fuel and

reduce CO₂emissions.

Start-Stop system*

In Start-Stop mode, the engine will automati-

cally switch off when the vehicle stops or is

stopping; for example when stopping at traf-

fic lights. The ignition remains switched on

during the stopping phase. The engine auto-

matically switches back on when required. In

this situation, the light of the

different from a car without four-wheel

drive. So do not be tempted to drive too fast

on firm or slippery roads just because the

vehicle still has good acceleration in these

conditions. Risk of accident!

wheels may start to “aquaplane” and lose

contact with the road if the car is driven too

fast. If this should happen, there will be no

sudden increase in engine speed to warn

the driver, as occurs with a front-wheel

drive car. For this reason you should always

choose a driving speed suitable for the

road conditions. Risk of accident!

Vehicles with a manual gearbox

●

Before stopping the vehicle or when it is

stopped, put it into neutral and release the

clutch pedal. The engine will switch off. The

warning lamp  will appear on the instru-

ment panel display. The engine may stop be-

fore the vehicle comes to a halt in the decel-

eration phase (at 7 km/h).
