Driver support systems  
Speed-dependent steering wheel  
resistance  
Speed-dependent power steering increases  
the steering wheel resistance in pace with  
the vehicle's speed, which can help give the  
driver an enhanced feeling of control and sta-  
bility.  
Steering is stiffer on highways. When parking  
and at low speeds, it will be easier to move  
the steering wheel.  
The vehicle is equipped with a number of  
driver support systems that can provide the  
driver with active or passive assistance in var-  
ious situations.

In rare situations, the power  
steering may become too hot and  
require temporary cooling – dur-  
ing such time the power steering  
will work at reduced output and the steer-  
ing wheel may feel more difficult to move.  
The message Power steering Assistance  
temporarily reduced will be displayed  
along with this symbol in the instrument  
panel.  
Some of the systems are standard and others  
are options. This also varies from market to  
market.

the system is intervening.  
The driver is advised to read all sec-  
tions in the Owner's Manual about this  
function to learn of its limitations,  
which the driver must be aware of  
before using the function.  
Changing the level of steering wheel  
resistance*  
In INDIVIDUAL drive mode, the level of steer-  
ing wheel resistance can be adjusted.  
When the system has inter-  
vened to apply the brakes, a  
pulsing sound may be heard  
and the vehicle may accelerate more slowly  
than expected when the accelerator pedal is  
depressed.

Driver support functions are not a sub-  
stitute for the driver's attention and  
judgment. The driver is always respon-  
sible for ensuring the vehicle is driven  
in a safe manner, at the appropriate  
speed, with an appropriate distance to  
other vehicles, and in accordance with  
current traffic rules and regulations.  
The system consists of the following sub-func-  
tions:

the driver can select ESC Sport Mode,  
which offers more active driving characteris-

spinning.  
Trailer Stability Assist* (p. 443)  
This function can also help prevent the wheels  
from spinning while the vehicle is accelerating.  
Engine drag control  
Engine drag control (EDC3) can help prevent  
inadvertent wheel lock, e.g. after downshifting  
or using engine braking when driving at low  
speeds on a slippery surface.  
Inadvertent wheel lock while driving could  
impair the driver's ability to steer the vehicle.  
When ESC Sport Mode is selected, the func-  
tion may seem to be disabled even though it  
continues to assist the driver.  
Trailer Stability Assist*4  
Trailer Stability Assist (TSA5) is designed to  
help stabilize a vehicle that is towing a trailer if  
the vehicle and trailer have begun to sway.  
When ESC Sport Mode is selected, the  
trailer stabilizer (TSA7) is switched off.  
Trailer Stability Assist is deactivated if ESC  
Sport Mode is activated.  
ESC Sport Mode also helps provide more  
traction, even if the vehicle gets stuck or is  
driving on a loose surface such as deep snow  
or loose sand.
