» Fig. 22 on page 28 shows the actual engine speed per
minute.
The beginning of the tachometer red scale range indicates the maximum per-
mitted speed for an engine that has been driven-in and has reached operating
temperature.
You should shift into the next highest gear before the red scale of the revolu-
tion counter is reached, or select mode D on the automatic gearbox.
The gear recommendation is important to note in order to maintain the opti-
mum engine speed » page 40.
CAUTION
The pointer of the tachometer must reach the red area for only a short time -
there is a risk of engine damage!
Coolant temperature gauge

Coolant temperature gauge
Read and observe on page 28 first.
The display » Fig. 23 provides information on the engine coolant temperature.
The display only works if the ignition is switched on.
Cold range
If the pointer is still in the left area of the scale, this indicates that the engine
has not yet reached its operating temperature. Avoid high speeds, full throttle
and high engine loads. This prevents possible damage to the engine.
The operating range
The engine has reached its operating temperature as soon as the pointer
moves into the middle of the scale A
» Fig. 23 .
High temperature range
If the pointer reaches the red area of the scale, the coolant temperature is too
high.
CAUTION
■ Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.■
Never cover the radiator - there is a risk of the engine overheating.

Brakes and parking
Introduction
This chapter contains information on the following subjects:
Information on braking
119
Handbrake
120
Parking
121WARNING■ Greater physical effort is required for braking when the engine is switch-
ed 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. Other-
wise, the functionality of the brake system may be impaired – risk of acci-
dent!
■
When leaving the vehicle never leave persons leave unattended in the
vehicle who could release the brake. The vehicle could then start to move –
risk of accident!
■
Observe the recommendations on the new brake pads » page 125, New
brake pads .
CAUTION
Never let the brakes slip with light pressure on the pedal if braking is not nec-
essary. This causes the brakes to overheat and can also result in a longer brak-
ing distance and excessive wear.
Information on braking
Read and observe
and on page 119 first.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv-
ing 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 by applying the brakes several times »
.
119Starting-off and Driving
Long or steep slopes
Before travelling a long distance with a steep gradient, reduce speed and shift
into the next lowest gear. As a result, the braking effect of the engine will be
used, reducing the load on the brakes. Any additional braking should be com-
pleted intermittently, not continuously.
Emergency brake display
If the brakes are applied in full and the vehicle systems evaluate the situation
as dangerous for the traffic following behind, the brake light flashes automati-
cally.
After the speed was reduced below around 10 km/h or the vehicle was stop-
ped, the brake light stops flashing and the hazard warning light system
switches on. The hazard warning light system is switched off automatically af-
ter accelerating or driving off again.
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 appropri-
ately, as you will not know the exact extent of the damage.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system.
The level of the brake fluid is monitored electronically » page 33,
Brake sys-
tem .
Brake booster
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.WARNINGOnly apply the brakes for the purpose of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users
in jeopardy.HandbrakeFig. 134
Handbrake
Read and observe and on page 119 first.
The hand brake is used when stopping and parking for securing the vehicle
against unwanted movement.
Apply
›
Pull the handbrake lever firmly upwards.
Release
›
Pull the handbrake lever up slightly and at the same time push in the lock
button » Fig. 134 .
›
Move the lever right down while pressing the lock button.
The handbrake indicator light lights up when the handbrake is applied, pro-
vided the ignition is on.
A warning signal sounds if the vehicle is inadvertently driven off with the
handbrake applied.
The following message is shown in the MAXI DOT display.
Release parking brake!
The handbrake warning is activated if the vehicle is driven at a speed of more
than around 5 km/h for more than 3 seconds.
WARNINGPlease note that the handbrake must be fully released. A handbrake which
is only partially released can result in the rear brakes overheating. This can
have a negative effect on the operation of the brake system – risk of acci-
dent!120Driving
The coolant additive share in the coolant must be at least. 40%.
The coolant additive may be increased to a maximum of 60%.
The correct mixing ratio of water and coolant additive is to be checked if nec-
essary by a specialist garage or is to be restored if necessary.
The description of the coolant is shown in the coolant expansion reservoir
» Fig. 170 on page 170 .WARNINGThe engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 165.■
The coolant is harmful to health.
■
Avoid contact with the coolant.
■
Coolant vapours are harmful to health.
■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurized!
■
When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot
coolant.
■
If any coolant splashes into your eyes, immediately rinse out your eyes
with clear water and contact a doctor as soon as possible.
■
Always keep the coolant in the original container, safe from people who
are not completely independent, especially children - there is a danger of
poisoning!
■
If coolant is swallowed, consult a doctor immediately.
■
Never spill operating fluids over the hot engine - risk of fire.
CAUTION
■ Do not continue if for some reason it is not possible to fill with coolant un-
der the current circumstances! Switch off the engine and seek assistance from
a specialist garage.■
If the expansion tank is empty, do not top up with coolant. The system could
fill with air - risk of engine damage,
stop driving! Switch off the engine and
seek assistance from a specialist garage.
■
The concentration of coolant additive in the coolant must never be under
40%.
■
Over 60% of coolant additive in the coolant reduces the antifreeze protec-
tion and cooling effect.
■
A coolant additive that does not comply with the correct specification can
significantly reduce the corrosion protection of the cooling system.
■ Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage.■
Do not fill the coolant above the mark
A
» Fig. 170 on page 170 .
■
If an error occurs, leading to the engine overheating, the help of a professio-
nal garage is to be sought - there is a risk of serious engine damage occurring.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.
Note
The coolant capacity is approximately 1 l greater on vehicles that are fitted
with an auxiliary heater (auxiliary heating and ventilation).
