Do not accelerate to prevent your vehi-
cle from rolling backwards on an uphill
gradient. Instead, you should either use
the handbrake or depress the brake ped-
al. This prevents excessive wear on the
clutch.
Select a lower gear (shift range
3, 2 or
1)
(
\2
page 204) in good time on long and
steep downhill gradients, especially if
towing a trailer. This prevents the brakes
from overheating and wearing too rapidly.
It is best not to stop the vehicle immedi-
ately after the brakes have been subject-
ed to an extreme load; continue driving
for a short time instead. The brakes are
cooled down more quickly in the airflow.The first time the brakes are applied af-
ter a long period of driving in heavy rain
without braking, it is possible that:
\4
there will be a delayed braking
response
\4
you will need to depress the brake
pedal more firmly
You should therefore maintain a greater
distance from the vehicle in front.
BrakingWarning
G
There is no power assistance for the ser-
vice brake when the engine is not running.
You will need to use significantly more
force to brake and could therefore lose
control of the vehicle and cause an acci-
dent.
Never switch off the engine while driving.
Warning
G
Make sure that other road users are not
put at risk by your braking.
