Start and driving
WARNING
●
Always adapt your driving style to the
traffic conditions.
●
Only use the Launch control programme
when road and traffic conditions permit,
and make sure your manner of driving and
accelerating the vehicle does not incon-
venience or endanger other road users.
●
Make sure that the ESC remains switched
on. Please note that when the TCS and ESC
are deactivated, the wheels may start to
spin, causing the vehicle to lose grip. Acci-
dent hazard!
●
After moving off, you should activate the
TCS or deactivate the ESC “sport” mode
again using the Infotainment system: func-
tion button > Assistants.
Note
●
After using the Launch control pro-
gramme, the temperature in the gearbox
may have increased considerably. In this
case, the programme could be disabled for
several minutes. The programme can be
used again after the cooling phase.
●
Accelerating with the launch control pro-
gramme places a heavy load on all parts of
the vehicle. This can result in increased
wear and tear.
Downhill assistant*
Downhill speed control is activated when the
lev
er is in the D/S position and the brake is
applied. An appropriate lower gear is engag-
ed.
The assistant attempts to maintain the speed
at which the vehicle was travelling when the
brake was applied, within logical limits. It may
be necessary to correct the speed by press-
ing the brake.
The assistant can only change down as far as
3rd gear. It is possible that on very steep
slopes you may have to switch to tiptronic
mode and thus manually change down to
2nd or 1st gear to take advantage of engine
braking and take the load off the brake sys-
tem.
Downhill speed control is deactivated as
soon as the road levels out again or you press
the accelerator pedal.
On vehicles with cruise control system*
›››
page 234, downhill speed control is acti-
vated when you set a cruising speed.
WARNING
The downhill speed control cannot defy the
laws of physics. Therefore, speed cannot be
maintained constant in all situations. Al-
ways be prepared to use the brakes!
Hill Hold Control (HHC)
When driving up a slope or using Offroad
with the le
ver in position D/S, stopping the
vehicle switches on the hill hold control.
When the brake pedal is released, the assis-
tant keeps the vehicle’s brakes applied for a
few seconds to give the driver time to press
the accelerator pedal and continue driving.
Inertia mode
The inertia mode allows you to travel certain
dist
ances without using the acceler
ator,
which saves fuel. Plan ahead and use the in-
ertia mode to “let” the vehicle “roll”.
Activation of the inertia mode
Condition: lever in position D, slopes of less
than 12% and speeds between 20 and 130
km / h (12 and 80 mph).
●
Gently take your foot off the accelerator.
The indication will be shown on the instru-
ment panel , the engaged gear and cur-
rent consumption will disappear and the
word Inertia will appear.
The gears will automatically disengage and
the vehicle will roll freely, without the effect
of the engine brake. While the vehicle rolls,
the engine runs at idling speed.
