Brake system*
This warning lamp lights up if the brake fluid level is too low
or if there is a fault in the system.
This warning lamp lights up if
● the brake fluid level is too low ⇒ page 219.
● there is a fault in the brake system.
This warning lamp can light up together with the ABS system warning lamp.
WARNING
● If the brake warning lamp does not go out, or if it lights up when driv-
ing, the brake fluid level ⇒ page 219, Brake fluid in the reservoir is too
low. Risk of accident. Stop the vehicle and do not drive on. Obtain techni-
cal assistance.
● If the brake warning lamp lights up together with the ABS warning
lamp , the control function of the ABS could be out of action. This could
cause the rear wheels to lock quickly when you brake. This could cause
the rear to break away. Risk of skidding. Stop the vehicle and seek tech-
nical assistance.

the tyre control lamp lights up. The wheel diameter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a load.
● The wheels of one axle are under more pressure (for example, driving
with a trailer or on extreme slopes).
● The vehicle is fitted with snow chains.

system works properly, the sensors must be kept clean and free of ice and
snow.
WARNING
● The sensors have blind spots in which obstacles may not be detected.
● Always look out for small children and animals because the system
will not always detect them. Always pay attention when reversing to
avoid accidents.
● The parking aid is not a replacement for driver awareness. The driver
must take full responsibility for parking and other manoeuvres.
CAUTION
● Please note that low obstacles detected by the system may no longer be
registered by the sensors as the car moves closer, so the system will not
give any further warning. Certain kinds of obstacles (such as wire fences,
chains, thin posts or trailer draw bars, high kerbs or painted railings etc)
may not always be detected by the system, so there is a risk of damaging
the vehicle in such cases.
● In some cases, obstacles with uniform edges and bumps may not be de-
tected immediately by the system due to their geometry. Take special care
of this type of obstacle (corners, rectangular objects, etc.), as they can
cause damage to the vehicle.
● Be especially careful when manoeuvring into a corner between two per-
pendicular walls. Pay special attention to the side distance from the wall us-
ing the mirrors.
● The parking aid system does not replace use of the mirrors for manoeu-
vres.
● External ultra-sonic sources (e.g. pneumatic drills, construction machi-
nery or other vehicles equipped with PND) may interfere with the operation
of the system. ●
Periodic cleaning of the sensors, take care not to damage or scratch
them. When cleaning with high pressure washers or steam cleaners, the
sensors should be sprayed for only a very short period and from a distance
of more than 10 cm.
● If the licence plate (especially the front one) is bent in such a way that it
noticeably juts out from the bumper, false alarms may sound for the front of
the vehicle.
Front parking aid with navigator view

view on the navigation
screen.
When the parking aid system has been activated, the navigation view
screen is also simultaneously activated (if one of the doors or the rear lid is
open, it must be closed before the on-screen information can be viewed).
The distance from the obstacle is estimated ⇒ Fig. 124 with help of seg-
ments around the vehicle. In the front area, the white segments indicate ob-
stacles located between 120 and 30 cm from the vehicle’s rear. In the rear
area, these indicate obstacles located between 160 and 30 cm from the ve-
hicle’s rear. As the vehicle approaches an obstacle, the segments are dis-
played closer to the vehicle. The red segments represent obstacles located
at less than 30 cm from the bumper. At this point the driver should not
move forward/reverse any further.
176Intelligent technology
The ASR helps the car to start moving, accelerate and climb a gradient in
slippery conditions, where this may otherwise be difficult or even impossi-
ble.
The ASR automatically switches on when the engine is started. If necessary,
it may be turned on or off by briefly pushing the ESC button on the centre
console.
When the ASR is off, the warning lamp is lit. The ASR should normally be
left on. Only in exceptional circumstances, when the slipping of the wheels
is required, can they be disconnected using the ESC button, for example.
● With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on loose surfaces
● When the vehicle is bogged-down, to free it by rocking.
The ASR should be switched on again as soon as possible.
WARNING
● Remember that not even the ASR can defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. The greater safety provided by the ASR should not
encourage you to run any risks.
CAUTION
● To ensure that the ASR works correctly, identical tyres should be fitted
on all four wheels. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
● Any modifications made to the vehicle (for example, to the engine,
brake system, running gear or to the combination of wheels and tyres) may
affect the operation of the ABS and ASR. XDS*
Driveshaft differential
When taking a bend, the driveshaft differential mechanism allows the outer
wheel to turn at a higher speed than the inner wheel. In this way, the wheel
that is turning faster (outer wheel) receives less drive torque than the inner
wheel. This may mean that in certain situations the torque delivered to the
inner wheel is too high, causing the wheels to spin. On the other hand, the
outer wheel is receiving a lower drive torque than it could transmit. This
causes an overall loss of lateral grip on the front axle, resulting in under-
steer or “lengthening” of the trajectory.
The XDS system can detect and correct this effect via the sensors and sig-
nals of the ESC.
Via the ESC, the XDS will brake the inside wheel and counter the excess
driving torque of that wheel. This means that the driver's desired trajectory
is much more precise,
The XDS system works in combination with the ESC and is always active,
even when the ASR traction control is disconnected.
Electronic Stability Control (ESC)*
General notes
The Electronic Stability Control increases the vehicle's stabil-
ity on the road. The Electronic Stability Control helps reduce the danger of skidding.
The Electronic Stability Control (ESC) includes the systems ABS, EDL and
ASR

Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.
In winter conditions winter tyres will considerably improve the vehicle's han-
dling. The design of summer tyres (width, rubber compound, tread pattern)
gives less grip on ice and snow.
The winter tyres must be inflated to a pressure 0.2 bar (2.9 psi / 20 kPa)
higher than the pressures specified for summer tyres (see sticker on fuel
tank flap) .
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes can be found in the vehicle's reg-
istration documentation. Use only radial winter tyres. All tyre sizes listed in
the vehicle documentation also apply to winter tyres.
Winter tyres lose their effectiveness when the tread is worn down to a depth
of 4 mm.
The speed rating code ⇒ page 225, New tyres and wheels determines the
following speed limits for winter tyres: ⇒
max. 160 km/h (99 mph)
max. 180 km/h (112 mph)
max. 190 km/h (118 mph)
max. 210 km/h (130 mph)
In some countries, vehicles which can exceed the speed rating of the fitted
tyre must have an appropriate sticker in the driver's field of view. These
stickers are available from your Technical Service. The legal requirements of
each country must be followed.
Do not have winter tyres fitted for unnecessarily long periods. Vehicles with
summer tyres handle better when the roads are free of snow and ice. Q
S
T
H If you have a flat tyre, please refer to the notes on the spare wheel
⇒ page 225, New tyres and wheels.
WARNING
The maximum speed for the winter tyres must not be exceeded. Other-
wise, this could lead to tyre damage and risk of accident.
For the sake of the environment
Fit your summer tyres again as soon as possible. They are quieter, do not
wear so quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front wheels, and only for the follow-
ing tyres:
175/70R14
185/60R15Chains with links not exceeding 15 mm (including the chain
closure)
215/45R16Chains with links not exceeding 9 mm (including the chain
closure)
215/40R17Chains with links not exceeding 7 mm (including the chain
closure)
Remove wheel hub covers and trim rings before fitting snow chains. For
safety reasons cover caps, available in any Technical Service, must then be
fitted over the wheel bolts.
WARNING
Snow chains should be correctly tightened in accordance with the manu-
facturer's instructions. This will prevent the chains coming into contact
with the wheel housing.
Safety FirstOperating instructionsPractical TipsTechnical Specifications
228Checking and refilling levels
CAUTION
Remove the snow chains to drive on roads without snow. Otherwise they
will impair handling, damage the tyres and wear out very quickly.
Note
In some countries, the maximum permitted speed with snow chains is
50 km/h (31 mph). The legal requirements of each country must be fol-
lowed.

Vehicle tools, spare wheel
Vehicle Tools
The vehicle tools are located under the floor panel in the
luggage compartment. – Lift luggage compartment floor panel.
– Take the vehicle tools out of the vehicle.
The vehicle tool kit includes:
● Jack*
● Hook to remove integral* trim and screw caps.
● Box spanner for wheel bolts*
● Towline anchorage*
● Adapter for the anti-theft wheel bolts*
Some of the items listed are only provided in certain model versions, or are
optional extras.
WARNING
● The factory-supplied jack is only designed for changing wheels on
this model. On no account attempt to use it for lifting heavier vehicles or
other loads. Risk of injury.
● Use the jack only on a firm, level ground.
WARNING (Continued)
● Never start the engine when the vehicle is on the jack. Risk of acci-
dent.
● If work is to be carried out underneath the vehicle, this must be se-
cured by suitable means. Otherwise, there is a risk of injury.
Spare wheel (temporary spare wheel)*
The spare wheel (temporary spare wheel) must only be used
for the minimum necessary time.
The temporary spare wheel is stored under the floor panel in the luggage
compartment and is attached by a thumbnut.
How to use the temporary spare wheel
If you ever have a punctured tyre or loss of pressure, the temporary spare
wheel is only intended for temporary use until you reach a workshop.
Change it for a duty wheel as soon as possible.
Please note the following restrictions when using the temporary spare
wheel. This temporary spare wheel has been specially designed for your ve-
hicle, thus, it cannot be changed with the temporary spare wheel from an-
other vehicle.
No other type of tyre (normal summer or winter tyre) may be fitted on the
compact temporary spare wheel rim.
Snow chains
For technical reasons, snow chains must not be used on the compact tem-
porary spare wheel.
Safety FirstOperating instructionsPractical TipsTechnical Specifications
230If and when
If you have a puncture on one of the front wheels when using snow chains,
fit the compact temporary spare wheel in place of one of the rear wheels.
You can then attach the snow chains to the wheel taken from the rear and
use this wheel to replace the punctured front wheel.
WARNING
● The tyre pressures must be checked and corrected as soon as possi-
ble after fitting the temporary spare wheel.
● Do not drive faster than 80 km/h (50 mph), since higher speeds can
cause an accident.
● Avoid heavy acceleration, hard braking and fast cornering. Risk of ac-
cident.
● Never use more than one temporary spare wheel at the same time,
risk of accident.
● No other type of tyre (normal summer or winter tyre) may be fitted on
the compact temporary spare wheel rim.
Tyre repair kit*
The tyre repair kit (for vehicles not including a temporary
spare wheel) is stored under the floor panel in the luggage
compartment. In the event of a punctured tyre, your vehicle is equipped with the Tyre Mo-
bility System (tyre repair kit).
The tyre repair kit consists of a container with sealing product to repair the
puncture and a compressor to generate the required tyre pressure. The kit
will reliably seal punctures up to a size of about 4 mm caused by the pene-
tration of a foreign body into the tyre.
Note
● Seek professional assistance if the repair of a tyre puncture is not possi-
ble with the sealing product.
Wheel change Preparation work
What you must do before changing a wheel.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible. Choose a location that is as
level as possible.
– All vehicle occupants should leave the vehicle. They should
wait in a safe area (for instance behind the roadside crash barri-
er).
– Switch the engine off. Switch the hazard warning lights on and
place the warning triangles in position.
– Apply the handbrake firmly.
– Engage the first gear , or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle.
– Take the vehicle tools and the spare wheel out of the luggage
compartment.

Description of specifications
Weights
Kerb weight refers to the basic model with a fuel tank filled to 90% capacity
and without optional extras. The figure quoted includes 75 kg to allow for
the weight of the driver.
For special versions and optional equipment fittings or for the addition of
accessories, the weight of the vehicle will increase ⇒
.
WARNING
● Please note that the centre of gravity may shift when transporting
heavy objects; this may affect vehicle handling and lead to an accident.
Always adjust your speed and driving style to suit road conditions and re-
quirements.
● Never exceed the gross axle weight rating or the gross vehicle weight
rating. If the allowed axle load or the allowed total weight is exceeded,
the driving characteristics of the vehicle may change, leading to acci-
dents, injuries and damage to the vehicle.
Towing a trailer Trailer weights
Trailer weight
The trailer weights and drawbar loads approved are selected in intensive tri-
als according to precisely defined criteria. The approved trailer weights are
valid for vehicles in the EU for maximum speeds of 80 km/h (50 mph) (in
certain circumstances up to 100 km/h (62 mph)). The figures may be differ-
ent in other countries. All data in the official vehicle documentation takes
precedence over these data at all times ⇒
.Drawbar loads
The maximum permitted drawbar load on the ball joint of the towing bracket
must not exceed
75 kg.
In the interest of road safety, we recommend that you always tow approach-
ing the maximum drawbar load. The response of the trailer on the road will
be poor if the drawbar load is too small.
If the maximum permissible drawbar load cannot be met (e.g. with small,
empty and light-weight single axle trailers or tandem axle trailers with a
wheelbase of less than 1 metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar load.
WARNING
● For safety reasons, you should not drive at speeds above 80 km/h (50
mph) when towing a trailer. This also applies to countries where higher
speeds are permitted.
● Never exceed the maximum trailer weights or the drawbar load. If the
permissible axle load or the permissible total weight is exceeded, the
driving characteristics of the vehicle may change, leading to accidents,
injuries and damage to the vehicle.
