causes you to run off the road before ESC can provide any assistance, you may not experience the
benefits of ESC.
ESC includes and/or works together with the ABS, BAS, ASR, EDL, and XDL systems (see below).
ESC is switched on all the time and cannot be switched off.
Anti-Lock Brake System (ABS)
ABS helps to keep the wheels from locking up and helps to maintain the driver's ability to steer and
control the vehicle. This means the vehicle is less likely to skid, even during hard braking:
x Push the brake pedal down hard and hold it there. Don't take your foot off the pedal or reduce the
force on the pedal!
x Do not “pump” the brake pedal or let up on it!
x Steer the vehicle while pushing down hard on the brake pedal.
x ABS stops working if you release or let up on the brake.
When ABS is doing its job, you will notice a slight vibration through the brake pedal and hear a
noise. ABS cannot shorten the stopping distance under all conditions. The stopping distance may
even be longer, for instance, when driving on gravel or on newly fallen snow covering an icy or
slippery surface.
Brake Assist (BAS)
The Brake Assist System can help to reduce stopping distances. If you press the brake pedal very
quickly, BAS detects an emergency situation. It then very quickly builds up full brake system pressure,
maximizing braking power and reducing the stopping distance. This way, ABS can be activated more
quickly and efficiently.
Do not reduce pressure on the brake pedal! BAS switches off automatically as soon as you release or
let up on the brake.
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 and XDL)
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.
XDL is an extension of the Electronic Differential Lock system. XDL does not react to drive wheel
slippage when driving straight ahead. Instead, XDL detects slippage of the inside front wheel during
fast cornering. XDL applies enough brake pressure to this wheel in order to stop the slippage. This
improves traction, which helps the vehicle stay on track.
Hill Hold helps keep the vehicle from rolling backwards when starting out on a hill, for example after
stopping at a traffic light. You don't have to apply and release the parking brake while depressing the
accelerator. For Hill Hold to work, the engine must be running and the vehicle must be in First Gear or
Reverse (manual transmission) or in Drive (D), Sport Drive (S), or Reverse (R) (automatic
transmission) and you must use the foot brake to hold the vehicle before starting to move.
Hill Hold keeps the brake applied for not quite 2 seconds with the same force you used to prevent the
vehicle from moving. This gives you time to take your foot off the brake, let the clutch out on a manual
transmission vehicle, and gently depress the accelerator to get the vehicle moving again. If you do not
depress the accelerator pedal and get the vehicle moving again within this time, the brakes will release
and the vehicle will roll downhill. Furthermore, if any requirement for engaging Hill Hold is no longer
met while the vehicle is stopped, Hill Hold disengages and the brakes are automatically released and
will no longer hold the vehicle.
Hill Hold is activated automatically when the following conditions are all met at the same
time.
Points 1 to 3 must all be met at the same time:
Step Manual transmission Automatic transmission
1. Hold the stopped vehicle on an incline with the foot or parking brake.
2. The engine must be running “smoothly.”
3.
A manual transmission vehicle must be in 1st
gear (1) if headed up a hill or in Reverse (R) if
backing up a hill; you must hold the clutch
down and the foot brake must be depressed
to keep the vehicle from moving.
An automatic transmission vehicle must be in
Reverse (R), Drive (D), or Sport Drive (S) and
the foot brake must be depressed to keep the
vehicle from moving.
4.
To drive off, take your foot off the brake pedal
as you let the clutch out and gently depress
the accelerator within 2 seconds.
To drive off, take your foot off the brake pedal
and gently depress the accelerator within
2 seconds.
Hill Hold is immediately deactivated:
x If any requirement listed in the table above is no longer met (see., Hill Hold is activated
automatically when the following conditions are all met at the same time.).
x If the engine is not running smoothly or the engine malfunctions.
x If the engine stalls or is switched off.
x Automatic transmission vehicles: If the transmission is in Neutral (N).
x Automatic transmission vehicles: If a tire does not have enough road contact (such as when the
vehicle is tipped or at an angle).
WARNING
The intelligent technology of Hill Hold cannot overcome the laws of physics. Never let the
increased convenience provided by Hill Hold tempt you into taking risks.
x The Hill Hold feature cannot hold the vehicle in all hill start situations (for example, if the
surface is icy or slippery).
x Hill Hold can only help keep the vehicle from moving for less than 2 seconds. After that,
the brakes will be released and the vehicle can roll down the hill.
