2009 MERCEDES-BENZ GL SUV oil level

G
Risk of accident
Grains of sand, particles of dirt and other
abrasive materials can enter the brake sys-
tem. This can lead to excessive wear and
unpredictable braking efficiency.
After the brakes have been exposed to dirty
conditions, have them checked and cleaned
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. Otherwise,
there is a risk that braking power may be
insufficient in the event of an emergency, or
that braking efficiency may be unpredictable.
Read this section before driving your vehicle
off-road. Practise by travelling over more gen-
tle off-road terrain first.
The following driving systems are specially
adapted to off-road driving:
R LOW RANGE off-road gear (Y page 114)
R off-road ABS (Y page 50)
R off-road 4-ETS (Y page 53)
R off-road ESP ®

G
Risk of accident
Damage to the vehicle creates the risk of an
accident for yourself and other road users. If
in doubt, have your vehicle checked at a quali-
fied specialist workshop which has the nec-
essary specialist knowledge and tools to carry
out the work required. Mercedes-Benz rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose. H
