- T he engine cannot be started by pushing
or towing the veh icle.
- If the engine has been under heavy load
for an extended period, heat builds up in

@ Tips
-You can apply the parking brake at any
time - even w ith the ignition switched
off. The ignit ion must be on in order to
release the parking brake.
- Occasiona l noises when the park ing
brake is applied and released are norma l
and are not a cause for concern.
- When the vehicle is parked, the parking
brake goes through a self-test cycle at
regular intervals. Any assoc iated noises
are norma l.
Parking
Various rules apply to prevent the parked ve­
hicle from rolling away accidentally.
P a rking
~ Stop the vehicle w ith the foot brake.
~ Pu ll the switch© to apply the parking
brake.
~ Se lect the P selector lever position
¢page 109.
~ Turn the eng ine off ¢,& .
In addition on incline s and grade s
~ Turn the steering wheel so that your vehicle
will roll against the curb in case it should
start to move.
A WARNING
-When you leave your veh icle - even if on­
ly b riefly - always take the ignition key
with you. This applies particu la rly when
children remain in the veh icle. Otherw ise
the ch ild ren could sta rt the engine, re­
lease the parking brake or operate elec­
trical equipment (e .g. power windows).
There is the risk of an accident.
- When the vehicle is locked, no one - par­
t icu larly not ch ildren should remain in

On th e ro ad 83
difficult for emergency workers to get in­
to the vehicle - putting lives at risk.
Starting from rest
The starting assist function ensures that the
parking broke is released automatically upon
starting.
Stopping and appl ying p arking brake
~ Pull the switch(®) to apply the pa rking
brake.
Sta rting and automaticall y releasing the
parking brak e
~ When you start to drive as us ual, the pa rk­
ing brake is automatically released and your
veh icle begins to move .
When stopp ing at a traffic signal or stopping
in city t raff ic, the parking b rake can be ap­
plied. The vehicle does not have to be held
with the footbrake. The parking brake elimi­
nates the tendency to creep w ith a dr ive range
engaged. As soon as you drive off as usua l,
the parking brake is released automatically
and the vehicle starts to move.
St arting on slope s
When starting on inclines, the sta rting assist
prevents the vehicle from unintentionally roll­
ing back. The braking force of the parking
brake is not re leased until suff ic ient driving
force has been built up at the wheels.
(D Tips
For safety reasons, the parking brake is re­
l eased automatically on ly when the driv­
er's safety belt is engaged in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
~ Keep the switch(®) pulled and depress the
accelerator. The parking brake stays applied
and prevents the vehicle from roll ing back-
