Operating noi se
Noises may occur when braki ng depend ing on the
speed, braking force and outside cond itions s uch
as temperature and humidity.
Due to the na ture of t he mate ria ls used in ce ram­
ic bra ke rotors*, noises m ay become mo re appa­
ren t at low speeds.
Effect of wat er and road salt
In ce rtain situat ions, for example after driving
through water, in heavy ra in, afte r ove rnig ht con­
densat ion or after washing your car, the braking
effe ct can be red uced by moisture or ice on the
b rake rotors and brake pads. The brakes must be
dried first w ith a few careful brake applications .
At highe r speeds and with t he windsh ie ld wipers
turned o n, the bra ke pads p ress against the bra ke
rotors for a short amount of time . This occ urs at
regular intervals without the driver noticing and
provides for better bra ke response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered road
and the brakes are not used. L ikewise, you clean
off accumu lated salt coat ing from brake discs
and pads with a few cautious applications of the
brake
c::> ,& .
Due to their sur face characteristics, ceramic
brake rotors* absorb mo isture in such condit ions.
This can cause a temporary reduction in braking
force compared to dry brakes. You can compen­
sate for this by pressing the brake peda l harder.
Cor rosion
There may be a tendency for dirt to b uild up on
the brake pads and corros ion to form on the discs
if the car is not driven regularly or only for short
tr ips with little use of the brakes.
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is adv isable to
clean off the pads and discs by brak ing firmly a
few t imes from a moderately high speed
c::> ,& .

Low brake fluid level
Malfunctions ca n occu r in the brake system if the
brake fluid level is too low . T he brake flu id leve l
is monitored elect ronically.

Brake lining wear status
Brake lining wear may be checked by visua l in­
spect ion of the cond ition of the brake pads
t hr ough the openings in the wheel. If necessary,
the wheel may be removed for t his inspection

.8_ WARNING
-New b rake p ads don't h ave the bes t stop­
p ing power an d must be "broken-in" during
the initial 250 miles (400 km) . The break-in
pe riod can be considerably longer for
veh icles with ceramic brake rotors*. You can
compensate for this by pressing the brake
pedal more firmly. This also applies late r
when new pads are installed.
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system only i f road co ndit ions pe rmit . Other road
users m ust not be put at r is k -you may
cause an ac cident!
- Before descending a steep g rade, reduce
speed and sh ift transmission into a lower
gear o r lower dr iving range. Do not r ide the
b ra kes or hold the pe dal down too long or
too often. This cou ld cause the b rakes to ge t
hot and dimin ish b raking effic iency .
- Do not " ride the bra kes" by rest ing you r foot
on the pedal when you do no t intend to
brake. This may cause the brakes to over­
heat, premature wear and increased stop­
p ing distance.

Driving and the
environment
Breaking in
New eng ine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km).
For the first 600 miles (1 ,000 kilometers):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than 2/3 of the max imum permitted RPM .
"' Avoid high eng ine speeds.
From 600 to 1 ,000 miles (1,000 to 1,500
kilometers ):
"' Speeds can gradually be increased to the maxi­
mum pe rm issib le road or e ngine speed.
During and after b reak-in period
"' Do not rev the engine up to high speeds when it
is cold . This applies whether the transmission is
in N (Neutral) or in gear .
After the bre ak-in period
"' Do not exceed maximum engine speed under
any circumstances .
"' Upshift into the nex t higher gear
before reach­
ing the red area at the end of the tachometer
sca le
c:::;, page 10.
During the first few hours of driving , the eng ine's
internal friction is higher than later when all the
mov ing parts have been broke n in. How well this
b reak-in process is done depends to a considera­
b le exte nt o n the way the veh icle is d rive n du ring
the first 1,0 00 miles (1,500 kilome ters).
(D Note
E xtremely high eng ine speeds a re au toma ti­
cally reduced. However, t hese rpm li mits are
p rogr amme d fo r an eng ine well run-in, not a
new engine .
Driving and the envir onment
{® For the sake of the environment
Do not drive with unnecessarily high engine
spe eds -upshifting early saves fuel, red uces
no ise and protects the environment.
New tires
If your vehicle is runni ng on new tires, drive par­
t icularly careful for the first 3S0 m iles (500 kilo ­
meters) after fitting .
_&. WARNING
New tires tend to be slippe ry and mus t also
b e "bro ken- in". Be sure to remembe r th is dur­
i ng the first 350 m iles ( 500 k ilome ters).
Brake gent ly . Avoid following closely behin d
other vehicles or other s ituations that might
require sudden, hard braking.
Avoid damaging the
vehicle
When you are dr iv ing on poor roads, or over
curbs, steep ramps, etc., make certai n that low ­
ly ing parts such as spo ile rs and exhaust system
parts do not bottom o ut and get damaged .
This is espec ially true for veh icles with low-s lung
chass is (sports c hass is)* and fully loaded
vehicles .
Catalytic converter
Applies to: vehicles with gasoline engine
It is very important that your emission control
system (catalytic converter) is functioning prop ­
erly to ensure that y our vehicle is running in an
environmen tally sound manner.

Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
ope rations.
Starting by pushing or
towing
(D Note
Veh icles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle .
If the engine shou ld fail to start because of a dis ­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumpe r cables to start the engine.
Jumper cables
Use only jumper cables of suffic iently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated term inal
clamps which are dis tinct ly marked :
plus(+) cable in most cases colored re d
minus( -) cable
in most cases colored blac k.
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for safe
handling of your vehicle's battery.
- Always shield your eyes and avo id leaning
over the battery whenever poss ible.
- A discharged battery can freeze at tempera­
tures just below 32 °F (0 °C) . Before con­
necting a jumper cable, you must thaw the
Emergency situations
frozen battery completely, otherwise it
could explode .
- Do not allow battery acid to contact eyes or
skin. Flush any contacted area with water immediately.
- Improper use of a booster battery to start a
vehicle may cause an exp losion.
- Vehicle batteries generate exp losive gases.
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery .
- The vo ltage of the booster battery must also
have a 12-Volt rating. The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batter ies of different voltage or substantial­
ly different "Ah" rating may cause an exp lo­
sion and personal injury .
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen . The battery case may have be weak­
ened .
- Use of batter ies of different voltage or sub ­
stantially different capacity (Ah) rating may
cause an exp losion and injury. The capac ity
(Ah) of the booster battery should not be
lowe r than that of the discharged battery.
- Before you check anything in the eng ine
compartment, always read and heed all
WARNINGS
r::!)page 220.
(D Note
-Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- Th ere must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
(+) terminals are connected.
(D Tips
- The discharged battery must be properly
connected to the vehicle's e lectrica l system. ..,.
271

Emergency situations
When jump starting or charging the bat­
tery, never connect the negative ground ca­
ble to the battery negative post because the
battery manager system must be able to de­
tect the battery's state of charge. Always
connect the negative ground cable to the
negative ground post of the battery manag­
er contro l unit.
Use of jumper cables
Make sure to connect the jumper cable clamps in
exactly the order described below!

Starting the engine
• Start the eng ine of the vehicle with the booster
battery @. Run the eng ine at a moderate
speed.
• Sta rt engine w ith discharged vehicle ba ttery @
in the usual manner.
• If the engine fails to start, do not keep the
starter cranking for longer than 10 seconds.
Wait for about 30 seconds and then try again.
• With engine running, remove jumper cables
from both vehicles in the exact
reverse order.
• Close the red cover on the positive terminal.
The battery is vented to the outside to prevent
gases from entering the vehicle interior . Make
sure that the jumper clamps are well connected
with their metal parts in full contact with the battery terminals.
&_ WARNING
To avoid ser ious personal injury and damage
to the vehicle, heed all warnings and instruc­
tions of the jumper cable manufacturer. If in
doubt, call for road service.
- Jumper cables must be long enough so that
the vehicles do not touch .
- When connecting jumper cables, make sure
that they cannot get caug ht in any moving
parts in the engine compartment.
- Before you check anything in the engine
compartment, always read and heed all
