Checklist before off-road driving
Engine oil level
Check the engine oil level with the oil
dipstick ( page 343).
Only with a proper oil level can the
vehicle obtain a trouble-free oil supply,
even on steep gradients.
!
If the engine oil level warning lamp
( page 434) comes on while driving, stop the
vehicle in a safe location or as soon at is safe to
do so. Check the engine oil level ( page 343).
The engine oil level warnings should not be
ignored. Extended driving with the symbol
displayed could result in serious engine damage
that is not covered by the Mercedes-Benz
Limited Warranty.

Tires
Check the tread depth and maintain
specified tire inflation pressure
(a placard with the recommended tire
inflation pressures is located on the
driver's door B-pillar ( page 352)).
Check tires for possible damage and
remove foreign objects.
Replace missing valve caps.
Rims
Dented or bent rims can cause tire in-
flation pressure loss and damage the
tire beads. For this reason, check and,
if necessary, change rims before driv-
ing off-road.
Vehicle tool kit
Check if the vehicle jack ( page 450)
is functional.
In all cases take the vehicle tool kit, a
strong tow rope, a shovel and a small
plank (to put under the vehicle jack on
sandy soil) with you.
