Anti-Slip Regulation (ASR)
ASR reduces engine power directed to spinning wheels and adjusts power to the road conditions.
Even under poor road conditions, ASR can make it easier to get moving, accelerate, and climb hills.
ESC and ASR can help when driving on loose surfaces (such as gravel) and in deep snow. If you get
stuck in deep snow, you may be able to get going again by “rocking” the vehicle back and forth. ESC
and ASR recognize this special driving situation and automatically increase the speed of the front
wheels. Keep pressing the accelerator and let ESC increase the speed of the front wheels to help you
keep moving or get moving again.
Electronic Differential Lock (EDL)
EDL is applied during regular straight-line acceleration. EDL gently brakes a drive wheel that has lost
traction (spinning) and redirects the drive force to other drive wheels. In extreme cases, EDL
automatically switches off to keep the brake from overheating. As soon as the brake has cooled down,
EDL automatically switches on again.
WARNING
Driving fast on icy, slippery, or wet roads can lead to a loss of control and result in serious
personal injury for you and your passengers.
x
Always adjust your speed and driving style to road, traffic, weather, and visibility
conditions. Never let the additional safety that ESC, ABS, BAS, ASR, and EDL can provide
tempt you into taking extra risks.
x
Braking assistance systems cannot overcome the laws of physics and always prevent
loss of vehicle control. Slippery and wet roads are still dangerous even with ESC and the
other systems!
x
Driving too fast on wet roads can cause the wheels to lose contact with the road and
“hydroplane.” A vehicle that has lost road contact cannot be braked, steered, or controlled.
x
These systems cannot reduce the risk of accident, for example if you drive too fast for
conditions or if you do not keep your distance from the vehicle in front of you.
x
Although these systems are very effective and can help you control the vehicle in many
difficult situations, always remember that your vehicle handling control is limited by tire
traction.
x
When accelerating on a slippery surface, for example on ice and snow, depress the
accelerator carefully. Even with these systems, the wheels may start to spin, leading to a loss
of vehicle control.
WARNING
The effectiveness of ESC can be significantly reduced if other components and systems that
affect vehicle dynamics, including but not limited to brakes, tires, and other systems
mentioned above, are not properly maintained or functioning.
x
Always remember that vehicle alterations or modifications can affect the functioning of
the ABS, BAS, ASR, EDL, and ESC systems.
x
Changing the vehicle suspension or using an unapproved tire / wheel combination can
change the way the ABS, BAS, ASR, EDL, and ESC systems work and reduce their
effectiveness.
x
The effectiveness of ESC is also determined by the tires fitted.
All 4 wheels must be equipped with identical tires in order for ESC and ASR to work properly.
Differences in the tread circumference of the tires can cause the system to reduce the engine power
when it is not expected.
