indication of hazardous road conditions, and functions as a reminder to take extra care while driving.
BAS (Brake Assist System) Observe the "Important safety notes" section (Y page 56). BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance. X Keep the brake pedal firmly depressed until
the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will function as usual once you release the brake pedal. BAS is deactivated.
56 Driving safety systems
G WARNING If the BAS malfunctions, the brake system still functions, but without the additional brake boost available that the BAS would normally provide in an emergency braking maneuver. Therefore, the braking distance may increase.
ESP® (Electronic Stability Program) General notes i Observe the "Important safety notes"
section (Y page 56).
ESP® monitors driving stability and traction, i.e. power transmission between the tires and the road surface. If ESP® detects that the vehicle is deviating from the direction desired by the driver, one or more wheels are braked to stabilize the vehicle. The engine output is also modified to keep the vehicle on the desired course within physical limits. ESP® assists the driver when pulling away on wet or slippery roads. ESP® can also stabilize the vehicle during braking.
ETS (Electronic Traction System) i Observe the "Important safety notes"
section (Y page 56).
Traction control is part of ESP®. Traction control brakes the drive wheels individually if they spin. This enables you to pull away and accelerate on slippery surfaces, for example if the road surface is slippery on one side. Traction control remains active, even if you deactivate ESP®.
Important safety notes G WARNING If ESP® is malfunctioning, ESP® is unable to stabilize the vehicle. Additionally, further driving safety systems are deactivated. This increases the risk of skidding and an accident.
Drive on carefully. Have ESP® checked at a qualified specialist workshop.
! Switch the ignition off when:
Rthe electric parking brake is being tested
using a brake dynamometer.
Rthe vehicle is being towed with the rear
axle raised.
Application of the brakes by ESP® may otherwise destroy the brake system.
When SPORT handling mode is activated, the M warning lamp lights up in the instrument panel. When ESP® is deactivated, the å and h warning lamps light up in the instrument panel. Observe the information on warning lamps (Y page 190) and display messages which may be shown in the instrument cluster (Y page 166). i Only use wheels with the recommended
tire sizes. Only then will ESP® function properly.
Characteristics of ESP® ESP® is activated automatically when the engine is started. If ESP® intervenes, the h ESP® warning lamp flashes in the instrument cluster. If ESP® intervenes: X Do not deactivate ESP® under any
circumstances.
X Only depress the accelerator pedal as far
as necessary when pulling away.
X Adapt your driving style to suit the
prevailing road and weather conditions.
Deactivating/activating ESP® Important safety notes i Observe the "Important safety notes"
section (Y page 54).
You can select between the following states of ESP®: RESP® is activated. RSPORT handling mode is activated. RESP® is deactivated. G WARNING When SPORT handling mode is activated, there is a greater risk of skidding and accidents. Only activate SPORT handling mode in the situations described in the following. G WARNING If you deactivate ESP®, ESP® no longer stabilizes the vehicle. There is an increased risk of skidding and an accident. Only deactivate ESP® in the situations described in the following.
In the following situations, it may be better to activate SPORT handling mode or deactivate ESP®: Rwhen using snow chains Rin deep snow Ron sand or gravel Rwhen driving on designated roads when the
vehicle's own oversteering and understeering characteristics are desired Driving in SPORT handling mode or without ESP® requires an extremely qualified and experienced driver. i Activate ESP® as soon as the situations described above no longer apply. ESP® will otherwise not be able to stabilize the vehicle if the vehicle starts to skid or a wheel starts to spin.
! Avoid spinning the driven wheels for an extended period with ESP® deactivated. You could otherwise damage the drivetrain.

Deactivating/activating ESP®
X To activate SPORT handling mode:
briefly press button :. The M warning lamp in the instrument cluster lights up. The SPORT handling SPORT handling mode mode message appears in the multifunction display. X To deactivate SPORT handling mode:
briefly press button :. The M warning lamp in the instrument cluster goes out. ESP® is activated.
X To deactivate ESP®: press and hold down button : until theh andå warning lamps in the instrument panel light up. The OFFOFF message appears in the multifunction display.
X To activate ESP®: when SPORT handling mode is activated or ESP® is deactivated, press button : briefly. The h and å warning lamps in the instrument cluster go out. TheONON message appears in the multifunction display. Characteristics of activated SPORT handling mode SPORT handling mode raises the intervention threshold for stabilizing the vehicle. This allows for a sportier driving style on designated race circuits and may in certain situations improve the traction in comparison with ESP®. If SPORT handling mode is activated and one or more wheels start to spin, the h warning lamp in the instrument cluster

flashes. ESP® only stabilizes the vehicle to a limited degree. When SPORT handling mode is activated: RESP® only improves driving stability to a
limited degree.
Rtraction control is still activated. RESP® still provides support when you brake
firmly.
Rengine torque is only restricted to a limited
degree, and the drive wheels are able to spin. The spinning wheels produce a cutting effect for better traction.
Characteristics when ESP® is deactivated If ESP® is deactivated and one or more wheels start to spin, the h warning lamp in the instrument cluster does not flash. In such situations, ESP® will not stabilize the vehicle. If you deactivate ESP®: RESP® no longer improves driving stability. Rtraction control is still activated. RESP® still provides support when you brake
firmly.
Rengine torque is no longer limited and the drive wheels are able to spin. The spinning wheels produce a cutting effect for better traction.
EBD (electronic brake force distribution) Observe the "Important safety notes" section (Y page 56). EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking. G WARNING If the EBD malfunctions, the brake system will still function with full brake boost. However, the rear wheels could lock up during emergency braking situations, for example. You could lose control of the vehicle and cause an accident.
Adapt your driving style to the changed driving characteristics.
ADAPTIVE BRAKE Observe the "Important safety notes" section (Y page 54). ADAPTIVE BRAKE enhances braking safety and offers increased braking comfort. In addition to the braking function, ADAPTIVE BRAKE also features the hill start assist function (Y page 115). For further information, see Driving tips (Y page 131).
Theft deterrent locking system Immobilizer The immobilizer prevents your vehicle from being started without the correct SmartKey. When leaving the vehicle, always take the SmartKey with you and lock the vehicle. The engine can be started by anyone with a valid SmartKey that is left inside the vehicle. X To activate with KEYLESS-GO: switch the
engine off and open the driver's door.
X To activate with the SmartKey: remove
the SmartKey from the ignition lock.
X To deactivate: switch on the ignition. i The immobilizer is always deactivated
when you start the engine. In the event that the engine cannot be started when the starter battery is fully charged, the immobilizer may be faulty. Contact an authorized Mercedes-Benz Center or call 1-800-FOR-MERCedes (in the USA) or 1-800-387-0100 (in Canada).
