Uphill driving
Danger!
Danger of serious personal injury or death
and risk of damage if the vehicle should
overturn.
f Do not turn around when driving uphill.
f If it is not possible to climb a gradient, the car
must be backed down in reverse gear.
f Do not drive over embankments or slopes at
steep diagonal angles.
f If the vehicle starts to tilt, immediately steer in
the direction of the tilt (line of slope).
f When driving uphill, never let the vehicle roll
backward when in idle or not in gear.
Exclusive use of the footbrake is too risky in
such situations.
