2003 VOLVO XC70 wheel torque

2003 VOLVO XC70
accelerating. This is done by temporarily reducing engine torque to the \
drive wheels, which helps
improve tractive force.
Under certain circumstances, such as when driving with snow chains, or d\
riving in deep snow or loose
sand, it may be advisable to temporarily switch off this function for ma\
ximum tractive force. This is
done by pressing the STC/DSTC button on the center control panel for at \
least a half a second.
When the SC function has been switched off:
l The text window will briefly display "SPIN CONTROL OFF"
l The LED in the STC/DSTC button will be off.
The following two functions are only available with DSTC:
3. Active Yaw Control (AYC)
This function helps maintain directional stability, for example when cor\
nering, by braking one or more
of the wheels if the car shows a tendency to skid or slide laterally. Th\
is is done by activating the Anti-
lock Braking System. A pulsating sound will be audible when the function\
is active, which is quite
normal. If you apply the brakes while this function is active, the brake\
pedal will feel stiffer than usual.
This is also one of the DSTC system's permanent functions and is not aff\
ected when the DSTC button on
the center control panel is pressed.
4. Emergency Brake Assistance (EBA)
The EBA function is an integrated part of the DSTC system. EBA is design\
ed to provide full brake
effect immediately in the event of sudden, hard braking. The system is a\
ctivated by the speed with which
you depress the brake pedal.
When the EBA system is activated, the brake pedal will go down and press\
ure in the brake system
immediately increases to the maximum level. Maintain full pressure on th\
e brake pedal in order to utilize
the system completely. EBA is automatically deactivated when the brake p\
edal is released.
When the car has been parked for some time, the brake pedal may sink mor\
e than usual when the engine
is started. This is normal and the pedal will return to its usual positi\
on when it is released.
* Standard on all models except the T5 turbo.
** Standard on the T5 turbo, option on all other models.

Attaching the jack
NOTE: To avoid excessive wear and the necessity of rebalancing, mark and reins\
tall wheels in the same
location and position as before removal. To lessen the chance of imbalan\
ce, each wheel hub is equipped
with a guide stud to ensure that a removed wheel can be reinstalled in i\
ts original position (as when
changing over to winter tires/wheels).
NOTE: Refer to
page 133 for hoisting the vehicle on a garage lift.

Jack for AWD models
CAUTION:
l The car must not be driven with wheels of different dimensions or with a\
spare tire other than the one
that came with the car. The use of different size wheels can seriously d\
amage your car's transmission.
l Correct tightening torque on wheel bolts must be observed. The wheel bol\
ts should never be greased
or lubricated. The extended, chromed wheel bolts must not be used with s\
teel rims, as they make it
impossible to fit the hub caps.
