3. Driving Directions
3.2.6 Hill hold control (HHC)
(applicable to some
models)
Hill Hold Control (HHC) is integrated in the ESP
system. HHC system allows the vehicle to start
on a hill without the parking brake applied, so
that the driver can easily move his/her feet onto
the accelerator pedal from the brake pedal to
prevent accidents.

HHC starting conditions
• When the slope is more than 4%, shift
lever isn't moved to "P" of "ON" position
(for models with G-DCT transmission),
and manual brake isn't pulled up or elec-
tronic parking brake isn't exerted, if the
driver steps the brake pedal to stop the
car or makes the car in stationary condi-
tion, at this moment, the driver releases
the brake pedal, and HAC is activated to
exert brake to the car. For a model with
MT transmission, the pressure will be
maintained for 1.5s after the brake pedal
is released. For a model with G-DCT
transmission, the pressure will be main-
tained for 1s.
• Under HAC working condition, when the
engine torque exceeds the resistance
torque of the car, the brake pressure will
be released to finish starting smoothly.
• For MT model, once the clutch is re -
leased, the HCC function is released im-
mediately.
• Under downhill condition, if the is shifted
to "R" position, HHC function is also
working.
Hint
• The HHC can apply the brake auto -
matically when starting on a steep
uphill or shifting into reverse when
going downhill, to prevent slipping.
• If the HHC fails, the ESP indicator
light is lit and the instrument cluster
display gives prompts accordingly.
