Speed-dependent steering force

The car is equipped with different driver sup-

port systems which can assist the driver in

different situations, either actively or pas-

sively.

For example, the systems can help the driver

to:

Speed related power steering causes the

steering wheel force to increase with the

speed of the car so as to be able to give the

driver enhanced sensitivity. On motorways

the steering is firmer. When parking and at

low speed steering is light and requires less

effort.

Reduced power

In rare situations, the power steering may

need to work at reduced power, and turning

the steering wheel may then seem slightly

heavier. This may occur when the power steer-

ing becomes too hot and then needs tempo-

rary cooling. It may also occur if the power

supply is disrupted.

DRIVER SUPPORT

Electronic stability control

WARNING

Electronic Stability Control (ESC¹) helps the

driver to avoid skidding and improves the

car's traction.

If the temperature increases too much, the

servo may be forced to switch off com-

pletely. In such a situation, the driver dis-

play shows the Power steering failure

Stop safely message, combined with a

symbol.

The function is supplementary driver

support intended to facilitate driving

and make it safer – it cannot handle all

situations in all traffic, weather and

road conditions.

•

The driver display shows this

symbol when the system is

engaged.

The driver is advised to read all sec-

tions in the Owner's Manual that relate

to this function to learn about factors

such as its limitations and what the

driver should be aware of before using

the system.

Braking from the system may

be heard as a pulsing sound,

The system consists of the following subfunc-

tions:

Driver support functions are not a sub-

stitute for the driver's attention and

judgement. The driver is always

responsible for ensuring the car is

driven in a safe manner, at the appro-

priate speed, with an appropriate dis-

tance to other vehicles, and in accord-

ance with current traffic rules and reg-

ulations.

DRIVER SUPPORT

Spin control and traction control

system

The function is active at low speed and brakes

the drive wheels that spin so that additional

traction shall be transferred from the drive

wheels that are not spinning.

Roll Stability Control

Electronic Stability Control in sport

mode

The stability system (ESC⁶) is always acti-

vated – it cannot be switched off. However,

the driver can select ESC Sport Mode,

which allows for a more active driving experi-

ence.

With the ESC Sport Mode subfunction

selected, intervention from the system is

reduced and the car is allowed to skid more

and greater control than normal is thus trans-

ferred to the driver.

This function reduces the risk of overturning,

for example during a sudden evasive manoeu-

vre or if the car skids. The system registers if

and how much the car's lateral inclination

changes. This information is used to calculate

the risk of the car overturning. If the car is at

risk, its electronic stability control system

engages, the engine torque is reduced and

one or more wheels are braked until the car

has regained its stability.

The function can also prevent the driving

wheels from spinning against the road surface

during acceleration.

Engine Drag Control

Engine Drag Control (EDC³) can prevent invol-

untary wheel locking, e.g. after shifting down

or engine braking when driving in low gear on

slippery road surfaces.

WARNING

When ESC Sport Mode is selected, the func-

tion can be considered as deactivated, despite

the function continuing to help the driver in

many cases.

Under normal driving conditions, the sys-

tem improves the car's road safety, but this

must not be taken as a reason to increase

speed. Always follow the normal precau-

tions for safe driving.

Involuntary wheel locking while driving can,

amongst other things, impair the driver's abil-

ity to steer the car.
