Handbrake
125WARNING■ Greater physical effort is required for braking when the engine is switched
off – risk of accident!■
During the braking procedure on a vehicle with manual transmission, when
the vehicle is in gear and at low revs, press the clutch pedal. Otherwise, the
function of the brake booster may be impaired – risk of accident!
■
Never leave children unattended in the vehicle. The children might, for ex-
ample, release the handbrake or take the vehicle out of gear. The vehicle could then start to move – risk of accident!
WARNINGIn the event of damage occurring to the standard fitted front spoiler or the
retrofitting of another front spoiler, wheel hubs etc. » page 184, Service work,
adjustments and technical alterations , It must be ensured that the air supply
to the front brakes is not impaired. The front brakes may overheat which can
have a negative impact on the functioning of the braking system – risk of acci- dent!
CAUTION
■ Observe the recommendations on the new brake pads » page 130.■Never let the brakes slip with light pressure on the pedal if braking is not neces-
sary. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.
Information on braking
First read and observe the introductory information and safety warn-
ings
on page 124.
If the brakes are applied in full and the control unit for the braking system consid-
ers the situation to be dangerous for the following traffic, the brake light flashes
automatically.
After the speed was reduced below around 10 km/h or the vehicle was stopped,
the brake light stops flashing and the hazard warning light system switches on.
The hazard warning light system is switched off automatically after accelerating
or driving off again.
Before driving a long distance at a steep incline, reduce speed and shift into the
next lowest gear. As a result, the braking effect of the engine will be used, reduc- ing the load on the brakes. Any additional braking should be completed intermit-tently, not continuously.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driving style.
The brake pads wear more quickly if a lot of journeys are completed in towns and over short distances or if a very sporty style of driving is adopted.
If operated under severe conditions , the thickness of the brake pads must be
checked by a specialist garage between service appointments as well.
Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake pads may be moist or have a coating of ice or layer of salt on them in winter. The
brakes are cleaned and dried by applying the brakes several times.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking
system. The brakes are cleaned and dried by applying the brakes several times.
Faults in the brake surface
If it is found that the braking distance has suddenly become longer and that the
brake pedal can be depressed further, the brake system may be faulty.
Visit a specialist garage immediately and adjust your style of driving appropriate-ly, as you will not know the exact extent of the damage.
124Driving
The intervention of the wizard is cancelled when you press the pedal and re-
sumed after the pedal is released again.
The hill descent assistant is automatically engaged under the following condi-tions.
The OFF ROAD mode is switched on and the warning light lights up in the
instrument cluster.
The vehicle engine is running and either the 1st, 2nd or 3rd gear, reverse gear
or no gear is engaged and the selector lever is in position R, N, D, S or Tip- tronic.
The downhill gradient is at least 10 % (when driving over sleepers, the limit can briefly drop to 8 %).
Neither the accelerator nor the brake pedal is operated.
It is however a requirement that the vehicle has sufficient grip on the soil. The Downhill Drive Support cannot properly fulfil its function on slushy soil due to
physical reasons (e.g. ice or mud).
For vehicles with manual transmission, the speed is maintained as follows.
› 1st gear - approx. 8 1)
- 30 km/h
› 2nd gear - approx. 13 1)
- 30 km/h
› 3rd gear - approx. 22 1)
- 30 km/h
› Reverse gear - approx. 9 1)
- 30 km/h
› Neutral for driving forwards - as well as driving backwards - approx. 2 - 30 km/h
On vehicles with automatic transmission, the speed is maintained as follows.
› Position D, S, R or Tiptronic (for 1st, 2nd, 3rd gear - approx. 2 - 30 km/h
› Neutral for driving forwards - as well as reversing - approx. 2 - 30 km/h
Start-Off Assist
The assistant supports the driver when starting eg on a steep slope. When the
driver presses the accelerator, the maximum engine speed is electronically limited so that a gentle approach is possible.
The overspeed trip unit is automatically deactivated after terminating the start-
up procedure.
As part of the Assist System, the accelerator pedal is adapted in its characteristics for an easier start-off on slippery and loose soil.ABS OFF ROAD
The ABS OFF ROAD supports the driver when braking on an unpaved surface such
as gravel, snow, etc.
The system generated by a controlled locking of the wheels braked wheel before a “wedge” of piled material, which shortens the braking distance.
The system is only available, if the front wheels are in the straight-ahead posi-
tion.
The system operates at speeds of up to 50 km/h.
TCS OFF ROAD
The ASR OFF ROAD makes starting and driving on an unpaved surface easier as it partially allows wheel-spin.
EDL OFF ROAD
The EDS supports OFF ROAD vehicle traction when driving on a surface with dif- ferent grip under the drive wheels or when driving over bumps.
A spinning wheel or wheels are braked earlier and with more force than with the
intervention of the standard EDS system.
Note
■ During an active intervention of the Downhill Drive Support, the brake lights do
not light up.■
When disabled, ASR » Fig. 116 on page 136 the OFF ROAD mode works without
the support of the ASR OFF ROAD.

The indicated values represent the average of the lower speed limits if a gear is engaged (depending
on the type of gearbox or engine).

Engine earth: START-STOP sys-
tem
First read and observe the introductory information and safety warn- ings on page 226.
On vehicles with the START-STOP system, the jump-start cable of the charger
must never be connected directly to the negative pole of the vehicle battery, but
only to the engine earth » Fig. 180.
Towing the vehicle
Introduction
This chapter contains information on the following subjects:
Front towing eye
229
Rear towing eye
229
Vehicles with a tow hitch
230
Vehicles with manual transmission may be towed in with a tow bar or a tow rope
or with the front or rear wheels raised.
Vehicles with automatic transmission may be towed in with a tow bar or a tow
rope or with the front wheels raised. If the vehicle is raised at rear, the automatic
gearbox is damaged!
A tow bar is the safest way of towing a vehicle and also minimises any shocks.
Only use a tow rope if a suitable tow bar is not available.
When towing, the following guidelines must be observed.
Driver of the tow vehicle›
Release the clutch particularly gently when starting off or depress the accelera-
tor particularly gently if the vehicle is fitted with an automatic gearbox.
›
On vehicles with a manual transmission, only push down on the accelerator pedal once the rope is taught.
The maximum towing speed is 50 km/h.
Driver of the towed vehicle
›
Switch on the ignition so that the steering wheel is not blocked and so that the
turn signal lights, horn, windscreen wipers and windscreen washer system can be used.
›
Take the vehicle out of gear or move the selector lever into position N if the ve-
hicle is fitted with an automatic gearbox.
Please note that the brake servo unit and power steering only operate if the en-
gine is running. If the engine is not running, significantly more physical force is re- quired to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught.
CAUTION
■ Do not tow start the engine – there is a risk of damaging the engine and the
catalytic converter! The battery from another vehicle can be used as a jump-start aid » page 226 , Jump-starting .■
If the gearbox no longer contains any oil because of a defect, your vehicle must
only be towed with the driven wheels raised clear of the ground or on a special
breakdown vehicle or trailer.
■
The vehicle must be transported on a special breakdown vehicle or trailer if it is
not possible to tow in the vehicle in the way described or if the towing distance is
greater than 50 km.
■
To protect both vehicles when tow-starting or towing, the tow rope should be
elastic. Thus one should only use plastic fibre rope or a rope made out of a simi-
larly elastic material.
■
While towing, take care to avoid impermissibly high tensile forces or jerky loads.
There is always a risk of excessive stresses and damage resulting at the points to which you attach the tow rope or tow bar when you attempt to tow a vehicle
which is not standing on a paved road.
■
Attach the tow rope or the tow bar to the towing eyes » page 229
or » page 229 to the detachable ball head of the towing device » page 152 .
