STARTING AND DRIVING

The towing eye may be used to pull the car up onto a recovery vehicle with a flatbed platform.The car's position and ground clearance deter-mine whether it is possible. If the slope of the recovery vehicle's ramp is too steep, or if the ground clearance under the car isinadequate, then the car may be damaged if youtry to pull it up using the towing eye. If necessary, raise the car by using the recovery vehicle's lifting device. Do not use the towing eye.
WARNING
No one/nothing is allowed to remain behind the recovery vehicle while the car pulled uponto the flatbed platform.
IMPORTANT
The towing eye is only designed for towing on roads -
not for pulling the car unstuck or out
of a ditch. Call a recovery service for recovery assistance.

Towing
During towing, one vehicle pulls another vehicle along behind it by means of a towline.
Find out the statutory maximum speed limit for towing before the towing begins.
Preparations and towing1. Activate the car's hazard warning flashers.
2. Secure the towline in the towing eye.
3. Deactivate the steering lock by unlocking the car.
NOTE
In ignition position II the steering lock is
deactivated if the car has been unlocked. See section “Ignition position” for more informa-tion.
4. Set the car in ignition position II by turning
the ignition dial to START and holding the
ignition dial in the START position for
approx. 4 seconds. Then release the knob, which automatically returns to its startingposition.
5. Move the gear selector to neutral position N
and release the parking brake.
> The towing vehicle can now start towing. 6. Keep the towline taut when the towing vehi-
cle reduces speed by holding your foot gen- tly pressed on the brake pedal - therebyavoiding unnecessary jerking.
7. Be prepared to brake to stop.
IMPORTANT
Note that the car must always be towed with the wheels rolling forward. • Do not tow cars with automatic transmis- sion at speeds higher than 80 km/h(50 mph) or for distances in excess of 80km.
WARNING
•Check that the steering lock is unlocked before towing.
• Ignition position
II must be active - in
ignition position I all airbags are deacti-
vated.
• Always keep the remote control key in thecar when it is being towed.
WARNING
The brake servo and power steering do not work when the engine is switched off - thebrake pedal needs to be depressedabout 5 times more heavily and the steering isconsiderably heavier than normal.

WHEELS AND TYRES
}}
* Option/accessory.495
IMPORTANT
Risk of overheating. The compressor must not run for more than 10 minutes.
5. Inflate the tyre to the pressure specified on
the tyre pressure label on the driver side door pillar. (Release air using the pressure reduc-ing valve if the tyre pressure is too high.)
6. Switch off the compressor. Detach the airhose and cable.
7. Refit the dust cap.

When changing wheels
The car's wheels can be changed, e.g. to winter wheels or a spare wheel.
Follow the relevant instructions for removing and fitting wheels.
When changing to another tyre
dimension
Check that the tyre dimension is approved foruse on the car. Contact an authorised Volvo workshop for updat- ing the software at each change of tyre dimen-sion. A software download may be necessaryboth when changing to larger and smaller dimen-sions, and also when switching between summerand winter wheels.

Engine compartment overview
The overview shows some service-related com- ponents.
The appearance of the engine compartment may differ depending on model and engine variant.
Coolant expansion tank
Reservoir for brake and clutch fluid (located on the driver's side)
Washer fluid filler pipe 7
Central electrical unit
Air filter
Engine oil filler pipe
WARNING
Remember that the radiator fan (located at the front of the engine compartment, behindthe radiator) may start automatically someafter the engine has been switched off. Always have the engine cleaned by a work- shop - an authorised Volvo workshop is rec-ommended. There is a risk of fire if the engineis hot.
WARNING
The ignition system works at a very high and hazardous voltage. The car's electrical system must always be in ignition position
0 when
work is being performed in the engine com- partment. Do not touch the spark plugs or ignition coil when the car's electrical system is in ignition position II or when the engine is hot.

Replacing the dipped beam bulb
The dipped beam bulb in halogen headlamps can be replaced by the driver.
Before the bulb can be replaced, the plastic cover over the headlamp must be removed; seethe section "Bulb replacement".
IMPORTANT
Never touch the glass part of the bulbs with your fingers. Grease from your fingers isvaporised by the heat, coating the reflectorand then causing damage.

AAccording to EN standard.
B Cold Cranking Amperes.
IMPORTANT
When replacing the starter battery or support battery, a battery of AGM 15
type must be fit-
ted.
NOTE
• The higher the current take-off in the car, the more the alternator must be workingand the batteries charging = Increasedfuel consumption.
• When the capacity of the starter batteryhas fallen below the lowest permissiblelevel then the Start/Stop function is dis-engaged.
Temporarily reduced Start/Stop function due to high current take-off means: •
The engine starts automatically 16
without the
driver depressing the clutch pedal (manualgearbox).
• The engine starts automatically without thedriver lifting his/her foot off the foot brakepedal (automatic gearbox).
The support battery normally requires no moreservice than the normal starter battery. A work-shop should be contacted in the event of ques-tions or problems - an authorised Volvo workshopis recommended.
IMPORTANT
If the following instruction is not observed then the Start/Stop function may temporarilycease to work after the connection of anexternal starter battery or battery charger:
• The negative battery terminal on the car's starter battery must
never be used for
connecting an external starter battery orbattery charger - only the car's negative
charging point may be used as the
grounding point.
NOTE
If the starter battery has been discharged so much that the car has no normal electricalfunctions and the engine is then jump-startedwith an external battery or a battery charger,the Start/Stop function will continue to beactivated. If the Start/Stop function thenauto-stops the engine shortly after, there is agreat risk that engine auto-start will fail dueto insufficient battery capacity, because thebattery has not had the opportunity torecharge. If the car has been jump-started, or if there is insufficient time to charge the battery with abattery charger, the recommendation is totemporarily deactivate the Start/Stop functionuntil the battery has been recharged by thecar. In an outside temperature of +15 °C, thebattery needs to be charged for at least1 hour by the car. In a lower outside tempera-ture, the charging time may increase to3-4 hours. The recommendation is to chargethe battery using an external battery charger.
