2004 MERCEDES-BENZ CLK COUPE snow chains

68 Safety
Driving safety
systems
In this section, you will find information
about the following driving safety system s:
! ABS(A nti-lock B raking S ystem)
! BAS (B rake As sist)
! ESP (E lectronic S tability P rogram)
i In wintry conditions, use winter tyres (M+S
tyres), with snow chains if ne cessary. The maxi-
mu m effect of ABS, BAS, ESP and SBC can only
be ac hievedin this way. ABS regulates the brake
pressure insuch a
way that the wheels do not lock when you
brake. This allows you to continue steer-
ing.
ABS works from a speed of approxi mately
8 km /hupwards, regardless of road sur-
face conditions.
ABS works on slip pery road surfaces, even
when you only brake gent ly.
The - indicator lamp in the instrument
cluster ( =page 12 )light s up when you
turn the keyto position 2in the ignition
lock. It goes out when the engine isrun-
ning. This indicates that ABS is opera-
tional. Dr
iving safety systems G
Risk of accident The risk of an acci
dent increases especially if
you:
! drive too fast, particularly when cornering
and ona wet or slippery road surfa ce
! drive too close to th evehicle in front
The driving safety systems described in this
section are unable to reduce this risk or over-
ride the laws of physics.
For this reason, always adapt your driving
style to suit the current road and weather con-
ditions and maintain asuffici en tdistanc efrom
other road users and objectsonthe road. ABS
G
Risk of accident Do not depress the brake pedal several times
in
qu ick succession (pumping). Depress the
brake firmly and evenly .Pumping the brake
ped alreduces the braking effect. 209en_d2.boo Seite

systems
! ESP only functions prop erly if whe els with
the recommended tyre sizes are used
( =
page 399).
The engine must not be running if:
! the parking brake is being teste dusing a
dynamometer
! the vehicle is being towed with the front axle
ra ised
Appli cation of the brakes by ESP may otherw ise
des troy the braking system on therear axl e. i
Only use wheels with the recommended tyre
si zes. Only then wil lESP function properly. Activating
/deactivating ESP
It may be best to deactivate ESP in the
following situations:
! if snow chains are being used
! in deep snow
! on sand or gra vel When you deactivate ESP:
! ESP no longer improves driving stability
! the engine's torque isthen no longer
limited and the drive wheels could spin.
This res ults in a cutting action ofthe
spinning wheels for better grip
! traction control is still activated
! you can still brake with support from
ESP
i Thev warning lamp in the instrument
clus ter flashes if ESP isdeactivated and one or
mor ewhe els start to spin. ESP doe snot then sta-
bil ise the vehic le. G
Risk of accident Proceed as follows if the
vwarning lamp
in the speedometer flashes:
! under no circumsta nces should you
de activate ESP
! onlydepress the accelerator pedal as
far as necessary when pulling away
! donot keep your foot onthe ac celerator
while you are driv ing
! adapt your driving sty leto suit the road
and weather conditions
Otherwise ,the vehicle could begin toskid.
ESP cannot reduce the risk of an accident if
you drive too fast. G
Riskofaccident Activate ESP as soon as th
esituations
described above no longer apply. ESP will
ot he rwi sebe unable to stabilise the vehicle
if the vehicle starts to skid or when a wheel
spins. 209en_d2.

252 Operation
Tyres and wheels
The tyre pressure loss warning system is
restricted in its function ordelayed if:
! snow chains are fitted to your vehicle
! road and traffic con ditions are affected
by wintry conditions
! you are driving ove ra loose surface
(e.g. sand or gravel)
! you adopt a sporty driving style (with
high cornering speed or rapid accelera-
tion)
! you are driving with a very heavy or
large trailer
! you are driving with roof loads or very
heavy loads Reactivating the
tyre pressure loss warning feature
You must reactivate the tyre pressure
loss
warning featur ein the following cases, if
you:
! have changed the tyre pressure
! have changed the wheels or tyres
! have fitted new wheels or tyres
6 Before reactivating, make sure that the
tyre pressure of all four tyres is set cor-
rectly for local driving conditions using
the table on the inside of the fuel filler
flap.
6 Make sure that the ignition is switched
on. G
Riskofaccident The tyre pressure loss warning system does
not warn
youof an inco rrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you to decide whether the tyre
pressur eshould be corrected.
The tyre pressure loss warning system isnot
a substitute for check ing the tyre pressures
on a regular basis sin ceequal pre ssureloss
in all fo urtyres cannot be detected by the
tyre pressure loss warning system.
Th etyre pressure loss warning system isnot
able to warn you of a sudden loss of pres-
sure, e.g. following penet ration by aforeign
obje ct. In such cases ,stop th evehicle by
braking carefully. Do notma keany sudden
steering movements. G
Risk of accident Th
ety re pre ssureloss warning system can
only work reliably if you have set the tyre
pressure correctly.
If an incorr ect tyre pressure is set, this in-
correct value will be monitored. 209en_d2.

258 Operation
Winter driving
Do not exceed the maximum permissible
spee d of 50 km /h. Remove the snow
chains as soon as pos sible if you are no
longer driving on snow-covered roads.
i Youmay wish to deactivate ESP when pull-
ing away on snow chains ( =
page 70). This will
help you to achieve an effective cutting action.
If you are intending to fit snow chains,
please remember the follow ing:
! Snow chains cannot be fitted on all
whee l/tyre combinations.
! Fit snow chains only to the rear wheels.
Comply with the manufacturer's instal-
lat ion instructions.
! Mercedes-Benz recommends that, for
safety reasons, you only use snow
chains wh ich have been approved for
Mercedes-Benz.
! Youmust not fit snow chains to AMG tyres. You should drive particularly carefully on
icy roads. Avoid sudden accelerati
on,
steering mo vements and braking.
If the vehicle threatens to skid or cannot
be brought to a standstill at a low speed:
! shift in toneut ral
! move the selector lever to N
! try to keep the vehicle under control
using corrective steering G
Risk of accident If you fit the spare wheel
*when driving with
winter tyres, pl ease be awarethat driving
stability will beimp aired owing to unstable
cornering characteristics cause dby the dif-
ferent tyres. You should ther efore adapt
your driving style and drive carefully.
Have the spare wheel* changed at the near-
est qualifi edspecialist workshop which has
the necessary specia list knowledge and
tools to carry out the work required.
Mercedes-Benz recomme nds that youuse a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-re lated systems must be car-
ried out at a qualified specialist workshop. Snow chains Winter driving
