Starting off with a trailer
T o prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator. The
parking brake stays applied and preve nts the vehicle
f rom rolling backward .
- You can release the switch o nce you are sure t hat you are
deve lop ing enough forward momentum at the whee ls as
you depress the accelerator.
Depending on the weight of the rig (vehicle and trailer) and the
severity of the incline, you may roll backwards as you start. You can
prevent rol ling backwards by holding the parki ng brake sw itch
pul led out and acce lerating -just as you would when starting on a
h ill with a conventional hand brake. •
Emergency braking
In the event that the conventi on al b rake system fails or
locks.
- Pull th e swi tch and continu e to pull it to slow you r veh icle
with t he par king brake in an emergency .
- As soon as you r elease the switch or acc elerate, the
braking pro cess s tops .
If you pull the swi tch and hold it above a speed of about 5 mph (8
km/h), the emergency braking function is initiated . T he vehicle is
braked at all fou r whee ls by activating the hydraulic brake system .
Brake performance is similar to making an emergency stop~&.
So that emergency braking is not activated by mistake, an audib le
warning tone (buzzer) sounds when the switch is pulled . As soon as the switch is released, or the accelerator pedal is depressed, emer­
gency b raking stops .
& WARNING
Emergency braking should only be u sed in an emergen cy, when
the normal foot br ake has f ailed or the br ake ped al i s obstructed .
U sing the parking brake to perform emergen cy brakin g will slow
yo ur vehicle a s if yo u had made a full brake app lication . The law s
of phy sic s cannot be su spe nded even with E SP and it s asso ciated
c ompon ents ( AB S, ASR, EDS ). In corner s and whe n ro ad or
w eather conditions are bad , a full brak e application can cau se the
vehi cle to skid or the r ear end to break a way -ri sking an
ac cident .•
