2009 SAAB 9-5 ESP

155 Starting and driving
Driving on hilly roads with a
heavy loadThe transmission fluid can overheat when
the gearbox is strained, for example, when
driving with a trailer on hilly roads. To avoid
the transmission fluid overheating, always
drive in Normal mode. The adaptive gear
change patterns are then active.
High air temperatures or a faulty oil cooler
can also cause the transmission fluid to
overheat. Overheating reduces the service
life of the fluid. Contact an authorized Saab
dealer (see also page 174).
Towing Towing of cars with automatic transmission,
see page 181.
Descending hillsIf the speed of the car increases while
descending a steep hill, despite the acceler-
ator being released, the control module will
change down a gear when you brake. If you
desire more powerful engine braking, man-
ually select a lower gear.
WARNING
Remember to use engine-braking (selec-
tor position D or L) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!

156 Starting and drivingSentronic, manual mode 3Move the selector lever to the M position.
Select a higher gear by pushing the
right-hand paddle on the steering
wheel. Select a lower gear by pushing the
left-hand paddle on the steering wheel.
An example of when you may wish to make
manual gear changes is when overtaking, to
enable you to remain in a low gear for an
extended period of time.
Changes from 3rd to 4th and from 4th to 5th
can be made when the engine speed is
above roughly 2,000 rpm.
If you select a gear that is judged too high by
the system, the selected gear position will
be shown briefly on the main instrument
panel and then the gear that is actually
engaged.If the road surface is slippery, you may wish
to pull off in 2nd or 3rd to reduce the risk of
wheel spin.
When descending hills you should select a
low gear to increase the braking effect of the
engine and thus spare the brakes.
Manual gear selections are shown on the
main instrument panel. The selector posi-
tion and the current gear are displayed.When the selector lever is in the M position,
as opposed to the D position, engines are
much more responsive to changes in accel-
erator position. The accelerator has a differ-
ent feel.
When in manual mode, kick-down operates
for 4th and 5th gears (below 2,000 rpm).
Kick-down cannot be activated in 1st, 2nd or
3rd gears.
For optimum performance, gear changes
should be made before reaching 6,000 rpm.
To avoid damaging the engine and trans-
mission, the transmission will shift up a gear
if the engine is in danger of overrevving. You
may feel a slight jolt before this gear change
is effected.

160 Starting and drivingTo reduce the preset speedThe cruise control system will always disen-
gage automatically the moment that either
the brake pedal or the clutch pedal is
depressed.
It is also possible to reduce the speed by
means of the RESUME/– button.
Sliding the button to RESUME/– once will
reduce the speed by 1 mph (1.6 km/h).
Holding the button in the RESUME/– posi-
tion will effect a gradual reduction in speed
until the button is released.
Disengaging the system The system will be disengaged:
 When the brake or clutch pedal is
depressed.
 When the switch is moved to CANCEL.
 When the switch is moved to OFF.
 When the engine is switched off.
 When the selector lever is moved to posi-
tion N (cars with automatic transmission).
 When the ESP
® system is operative for
more than 1 second.
BrakingTo avoid the brakes becoming overheated,
(e.g. when negotiating long descents with a
drop of several hundred feet), select a low
gear to use the braking effect of the engine.
If the car has automatic transmission, move
the selector lever to position D or L.
When driving fast, you can help to prolong
the life of the brakes by thinking ahead and
braking harder for short periods, rather than
braking more moderately over long
stretches. Brake pad wear indicatorsThe outboard brake pads on the front
wheels incorporate pad-wear indicators.
When the lining is down to 3 mm, the pad
will produce a screeching, squealing or
scraping noise when the brakes are applied.
New pads should be fitted without delay.
Brake pads should only be replaced by a
workshop. We recommend that you con-
tact an authorized Saab dealer.

161 Starting and driving

ABS brakes
ABS (antilock braking system) modulates
the brake pressure to the respective
wheels. Wheel sensors detect if a wheel is
about to lock, and the control module
reduces the pressure to that wheel and then
increases it once more until the tendency is
detected again.
The brake system is equipped with an Elec-
tronic Brake-force Distribution device
(EBD), which distributes the brake pressure
between the front and rear wheels, in such
a way as to achieve optimum braking perfor-
mance irrespective of the car’s speed and
load.
WARNING
 It is prudent to try your brakes from
time to time, especially when driving in
heavy rain, through water collected on
the road, in snow, on a wet road sur-
face or in salty slush. In such condi-
tions, the brakes may take longer than
normal to take effect. To rectify this,
touch the brake pedal periodically to
dry the brakes out.
 The same applies after the car has
been washed or when the weather is
very humid.
 Avoid parking the car with wet brakes.
Before parking, and if the traffic condi-
tions allow, brake quite heavily so that
the brake discs and pads warm up and
dry.
 The brakes are power assisted and it
should be kept in mind that the servo
unit only provides the power assis-
tance when the engine is running.
 The brake pressure required when the
engine is off,(e.g. when the car is
being towed) is roughly four times the
normal pedal force required. The
pedal also feels hard and unre-
sponsive.
WARNING
 The additional safety afforded by the
ABS system is not designed to allow
drivers to drive faster but to make
normal driving safer.
 To stop as quickly as possible, without
loss of directional stability, whether
the road surface is dry, wet or slippery,
press the brake pedal down hard-
without letting up (do not pump the
pedal), declutching simulta-
neously, and steer the car to safety.

163 Starting and driving
Electronic Stability
Program (ESP
®)
The system employs both the antilock brak-
ing system (ABS) and the traction control
system (TCS). It is a system that helps the
driver to stabilize the car in unusual circum-
stances that would otherwise be more diffi-
cult to handle.
How the ESP
® system works
The system can help to prevent the car from
skidding by braking one or several wheels
independently of the driver. The engine
output is then also reduced to prevent the
driving wheels from spinning. The car has
sensors that measure wheel speed, yaw
acceleration, lateral acceleration, steering
wheel position and braking pressure. The
values provided by these sensors are used
to calculate the actual direction of the car. If
this direction does not agree with that
intended by the driver, calculated from the
steering wheel position, the ESP
® is
engaged.
The ESP
® system improves the driver’s
chances of retaining control over the car in
critical situations.
To ensure that the system works as
designed, the dimensions of all four tires
must be the same.
WARNING
When driving normally, the ESP
® system
will help to improve the stability of the car.
This does not mean that car can be driven
faster. The same care and prudence as
normally applied should be displayed on
cornering and when driving on slippery
roads.
The illustration shows how the system
brakes one or more wheels (and with var-
ying braking force for each wheel) in order
to increase the car’s chances of following
the direction in which the driver wants to
drive.

164 Starting and drivingThe ESP
® indicator light
The indicator light on the main instru-
ment comes on for a short period of time
when the ESP
® system is operative.
Operation of the ESP
® system indicates
reduced cohesion between the tires and the
road, and that extra care should be taken by
the driver.
The ESP
® OFF-indicator light
The light on the main instrument comes
on if:
 A fault has been detected and the system
has therefore been switched off.
 The system has been switched off manu-
ally.
When the ignition key is turned to the ON
position, the lamp is lit for about four sec-
onds while the system undergoes a
self-test.
Temporarily turning the ESP
®
system off
The system can be turned off manually with
the ESP
® button, whereupon the light
on the main instrument panel will come on.
The ESP® system cannot be switched off if
the car is travelling faster than 35 mph
(60 km/h).
The ESP® system is always operative
during braking, even if it has been switched
off manually.
NOTICESuspension modifications, such as
changing the type of wheels, dampers or
springs, can affect the function of the
ESP
® system.
Always consult a workshop before chang-
ing any suspension components. We rec-
ommend that you contact an authorized
Saab dealer.

168 Starting and drivingSaab Parking
Assistance3The parking aid system facilitates parking
and reversing. There are four sensors in
the rear bumper that detect objects up to
6 feet (1.8 metres) behind the car.The system uses four sensors in the rear
bumper. These emit ultrasound signals that
bounce back to the sensors off any objects
behind the car. The system, however,
cannot always detect small or narrow
objects or objects that do not reflect ultra-
sound back towards the car, such as pipes,
or the corner of a house or rectangular post.The system is activated automatically when
reverse is engaged or selected. When the
sensors detect an object within the moni-
tored area, the SID will display the text
"PARK ASSIST" and pulses of sound
(- - - - -) will be heard. The frequency of the
pulses increases as the car comes closer to
the object.
When the distance to the object is less
than 12 in. (30 cm), a continuous tone
will be heard.
WARNING
Responsibility always lies with the driver
when reversing.
 Saab Parking Assistance can facilitate
reversing at low speeds, such as when
reverse parking.
 Bear in mind that small and/or narrow
objects cannot always be detected by
the system.

173 Starting and driving
If winter tires are fitted, the same type must
be fitted on all wheels. Your Saab dealer will
be pleased to advise you on the best tires for
your car.
Remember that tires age. It may therefore
be necessary to change them before they
reach the legal wear limit, as they gradually
lose their friction properties.
The best response if the car gets into a
front-wheel skid is to freewheel (manual
gearbox only), i.e. disengage the clutch (so
that the wheels are neither driven or
retarded by the engine.
If the car has automatic transmission, ease
up on the accelerator and steer carefully in
the desired direction.
In a rear-wheel skid, steer in the same direc-
tion that the rear of the car is moving.
Tire chains3If you want to fit tire chains (where legally
permitted) they should only be fitted to the
tires recommended under ”Specifications”
(see page 261).
Consult your Saab dealer for details of
approved tire chains.
Driving in hot weatherAlways check the coolant level before start-
ing a journey. When the engine is cold, the
coolant shall lie on or just above the
KALT/COLD mark on the expansion tank..
At the end of a journey, if the engine has
worked hard, allow it to idle for two or three
minutes before switching it off.
If the needle on the temperature gauge
enters the red zone:
1 Bring the car to a standstill but leave the
engine running. Do not remove the cap
on the expansion tank even if the tank is
empty. If the needle on the temperature
gauge continues to rise while the engine
is idling, switch off the engine.
WARNING
 Do not exceed 30 mph (50 km/h)
when tire chains are fitted.
 Tire chains can reduce the directional
stability of the car.
 Tire chains must not be used on the
rear wheels. NOTICE Check the links frequently for wear.
 Check that the chains do not contact
the wheel-arch liner at full lock.
 See section ”Specifications”,
page 261, for information on allowable
wheel dimensions for the fitting of tire
chains.
