Passive Safety - Mercedes-Benz GLK-Class Service Manual

Passive safety

Passive safety features include:
• Body structure with high-rigidity passenger cell
• Front and rear structures with high energy
absorption potential due to deformation
• Compact V6 engine, mounted on a bolted frame-
type integral support which deforms in the
direction of impact
• Several parallel load paths for improved load distri-
bution in the event of a partial head-on collision
• Strut installed under the wind deflector from the
spring tower to the crossmember to reduce
movement of the shock absorber tower and
prevent the pedals from being pushed backwards
as a result
• Use of a crash joint between fender and driver door
and between driver and rear door to prevent the
fender and driver door from overlapping and to
reduce the required door opening force after an
impact
• Cockpit crossmember made out of extruded
aluminum section between the A-pillars
• Telescoping steering column with collapsible tube
• Doors with reinforcement profiles
• Cargo retention with anchoring lugs and cargo net
• Pyrofuse in the prefuse box that isolates the starter
and alternator lines from the battery in certain
accident situations
• Armrests and assist handles on door trim have
been strengthened by additional safety measures
