Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the eng ine is running. ESC detects
certain difficult driv ing situations, including
when the vehicle is beginning to spin (yaw) out of cont ro l and he lps you to get the vehicle
back under control by select ively b rak ing the
wheels, and/or red ucing engine power and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
DJ in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle
hydroplanes (rides on a c ush ion of water in­
stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 171
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather conditions . ESC can­
not override the vehicle's physical lim its, in­
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
driver ina ttent io n. Instead , ESC imp roves the
poss ibility of keep ing the vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering i nputs to
help keep the vehicle go ing in the intended di­
rect ion. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC is switched on all the time. In certain sit­
uat ions when you need less traction, you can
switch off ASR by pressing the butto n
[ill
~ page 173, fig. 166 or~ page 173,
fig. 167. Be sure to sw itch ASR on aga in when
you no lo nger need less traction.
The following systems are integrated in the
ESC:
Anti-lock bra king sy stem (ABS )
ABS prevents the whee ls from locking up
when brak ing. T he vehicle can st ill be steered
even dur ing hard braking. App ly steady pres­
su re to the brake peda l. Do not pump the ped­
al. A pulsing in the brake pedal ind icates that
the system is helping you to brake the veh icle .
Brake assi st system
The brake ass ist system can decrease braking
distance. It increases brak ing power when the
drive r presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the s ituation is over. In
vehicles with adaptive c ruise control*, the
brake assis t system is more sensitive if the

A WARNING
Take the following precautions after re ­
pairing the tire:
- Do not drive faster than 50 mph (80 km/
h)!
- Avoid fu ll-throttle acce leration, heavy
braking and fast cornering.
- The vehicle's road behavior can be affect ­
ed.
- Tires sealed w ith
TMS are intended only
for
temporary, short-te rm u se . Dam­
aged tires must be replaced . Drive care­
fully to the next profess iona l repa ir fa ­
c ility.
- After using the t ire sea lant the tire pres­
sure monitoring system may no longer
work properly. Drive carefully to the next
professional repair fac ility.
- TMS must NOT be used,
- for cuts or punctures in the ti re whi ch
a re l arger tha n 0.16 inch (4 mm)
- for damage to the rim
- if you have been dr iv ing with very low
tire pressures o r ti res with no air
- Seek p rofess ional assistance if it is not
poss ible to repair the tire with the tire
sealant.
- The tire sealant must not come into con­ tact with sk in, eyes or clothing.
- If you get any tire sealant in your eyes or
come into contact with it, r inse the af­
fected a rea t horoughly with cl ean water.
F ind a physicia n immediate ly!
- Change a ny clot hing contam ina ted with
t ir e sea lant immed iate ly.
- Do not inhale the vapo r!
- If you have swallowed t ire sealant, r inse
your mouth thorough ly r ight away a nd
dr ink plenty of water.

(D Note
Do not use comme rcially avai lab le tire
sea lants. T he e lectr ica l components of the
tire pressure monitoring system will no
l onger work properly.
@ For the sake of the environment
Used sealant bottles can be dropped off at
a recycling facility.
(D Tips
- If sea lant has run out, allow it to dry .
Then you can peel it off.
