Stopping and starting on hills 
If you stop on a hill with the vehicle in gear, you must depress the brake pedal or engage the 
electronic parking brake to keep the vehicle from rolling. Do not release the brake pedal or the parking 
brake until the vehicle has started to move forwards ⇒ . 
Kick-down acceleration 
The kick-down feature permits maximum acceleration when the selector lever is in the Drive (D), Sport 
Drive (S) or Tiptronic mode. 
If you push the accelerator all the way down, the vehicle will automatically downshift, depending on 
vehicle speed and engine speed (rpm). This feature lets you take advantage of the full acceleration 
capacity of the vehicle ⇒ . 
With kick-down actuated, the transmission will stay in the current gear longer and not upshift until the 
engine reaches maximum rpm. 
 .WARNING 
Rapid acceleration can cause skidding and loss of traction, especially on slippery roads, 
resulting in a loss of vehicle control, collisions, and serious personal injury. 
 x Always adapt your driving to the traffic flow.  
 .NOTICE 
 x When stopping on hills with the transmission in a drive gear, do not use the accelerator to 
help prevent the vehicle from rolling backwards. This can cause the automatic transmission to 
overheat and be damaged. 
 x Never let the vehicle coast or roll down a hill in Neutral (N), especially when the engine is 
not running. The transmission will not be lubricated and will be damaged.

Driving 
situations Requirements and conditions Vehicle behavior 
– CAReful use of E-MODE button 
⇒ fig. 251. 
The high-voltage battery discharges quickly 
with the E-MODE button switched on. This 
can increase fuel consumption since driving 
in electric mode is preferred in this case, 
even though the combustion engine would 
be more efficient. 
Driving on 
country roads 
and highways. 
– Conscious easing off of the 
accelerator, to enable longer sailing 
distance. 
By easing off the accelerator, the 
combustion engine is automatically 
switched off and de-clutched. The vehicle 
glides without engine power. 
- Reducing speed by easing off the 
accelerator early and not by 
braking. 
Sailing possible. Reduction of speed this 
way is more fuel-efficient than through 
braking. 
- Avoid speeds of over about 160 
km/h (99 mph). 
Efficient sailing is possible with a speed of 
about 160 km/h (99 mph)  . 
- CAReful selection of gear (S). 
Sporty driving style with activated sport 
programme increases fuel consumption. 
Efficient sailing in sport programme with 
combustion engine automatically switched 
off is possible with a speed of about 70 
km/h (43 mph). 
Driving in cold 
months. 
- Do not warm up the combustion 
engine by running it with the 
vehicle stationary. 
The temperature of the combustion engine 
increases very slowly, but fuel consumption 
increases considerably. 
– CAReful use of heating for 
windshield and the rear window, 
outside mirror, seat and steering 
wheel. 
This prevents energy from being lost and 
saves energy for the electric motor. 
- Never leave the vehicle in a 
garage over night. 
This prevents the high-voltage battery and 
the vehicle interior from cooling down too 
much. The optimal temperature of the high-
voltage battery is reached quicker at the 
beginning of the journey and the 
combustion engine can be switched off 
quicker when the vehicle interior is 
sufficiently heated.
