STARTING AND DRIVING
433
Driving through standing water
It may be necessary to drive the vehicle through standing water, e.g. deep puddles orflooding on the road. This must be done withgreat caution.
To help prevent damage to the vehicle when driving through water:
Do not drive in water higher than the floorof the vehicle. If possible, check the depthof the water at its deepest point beforedriving through it. Be particularly carefulwhen driving through flowing water.
Do not drive faster than walking speed.
Do not stop the vehicle in the water. Drivecarefully forward or back the vehicle out ofthe water.
Remember that waves created by passingvehicles could cause the water level to riseabove the vehicle's floor level.
Avoid driving through salt water to helpavoid the risk of corrosion.
CAUTION
Parts of the vehicle (e.g. engine, transmis- sion, driveline, electrical components, etc.)can be damaged if the vehicle is driventhrough water higher than its floor level.Damage to any components caused byflooding, vapor lock or insufficient oil is notcovered under warranty. If the engine stalls while the vehicle is in water, do not attempt to restart it. Havethe vehicle towed on the bed of a towtruck to a workshop - an authorized Volvoworkshop is recommended.
CAUTION
Because it can be difficult to determine the water depth, Volvo recommends not driv-ing through standing or running water. Thedriver is always responsible for operatingthe vehicle in a safe manner and adheringto all applicable laws and regulations.
When you have passed the water, press lightly on the brake pedal and check that the brakesare functioning properly. Water, mud, slush,etc. can make the brake linings slippery,resulting in delayed braking effect. If the vehicle is equipped with a trailer cou- pling contact, clean the contact after driving inwater or mud.

WHEELS AND TIRES
542
CAUTION
Snow chains can be used on the vehicle, with the following restrictions:
Always follow the manufacturer'sinstallation instructions carefully. Installchains as tightly as possible andretighten periodically.
Only put snow chains on the frontwheels (also applies to all-wheel drivevehicles).
If accessory, aftermarket or "custom"tires and wheels with different dimen-sions than the original tires and wheelsare used, snow chains in some casesmay NOT be used. Sufficient distancebetween the chains and brakes, sus-pension and body components mustbe maintained.
Check local regulations regarding theuse of snow chains before installing.
Never exceed the snow chain manu-facturer's specified maximum speedlimit. Under no circumstances shouldyou exceed 50 km/h (30 mph).
Avoid bumps, holes or sharp turnswhen driving with snow chains.
Avoid driving on surfaces withoutsnow as this wears out both the snowchains and the tires.
The handling of the vehicle can be adversely affected when driving withchains. Avoid fast or sharp turns aswell as locked wheel braking.
Some types of strap-on chains affectbrake components and therefore mustNOT be used.
Consult a Volvo retailer for more information about snow chains.

MAINTENANCE AND SERVICE

Automatic car washes
The vehicle should be washed as soon as it becomes dirty. The longer the dirt remains,the more difficult it will be to keep the vehicleclean. It could also lead to paint damage.
Washing your vehicle in an automatic car wash is a fast and easy way to keep your vehi-cle clean, but it does not reach all areas of thevehicle. Volvo recommends washing yourvehicle by hand or supplementing automaticcar washes with a hand wash.
NOTE
Volvo recommends not washing the vehi- cle in an automatic car wash during thefirst few months; the paintwork on newvehicles takes some time to fully harden.
CAUTION
Before driving the vehicle into a car wash, deactivate the Automatic Braking whenStationary and Automatic Parking BrakeApplication functions. If the functions arenot deactivated, the brake system willseize when the vehicle is stationary and thevehicle will not be able to roll.
CAUTION
For automatic car washes in which the vehicle is pulled forward on rolling wheels:
1. Before washing the vehicle, make sure that the automatic rain sensor is deac- tivated. If it is not deactivated andinadvertently starts, the wiper armscould be damaged.
2. To help prevent damage from the auto- matic car wash machinery, make surethat the door mirrors are folded in,antennas retracted or removed, andany auxiliary lights secured.
3. Drive into the automatic car wash.
4. Turn off the "Automatic Braking when Stationary" function using the
but-
ton in the tunnel console.
5. Turn off the "Automatic Parking Brake Application" function in the center dis- play's Top view.
6. Turn off the engine by turning the start knob in the tunnel console clockwise.Hold the knob in position for at least2 seconds.
The vehicle is now ready for the automaticcar wash.
CAUTION
The system will automatically change to P
mode if the above steps are not followed. In P mode, the wheels are locked, which
they should not be when the vehicle isbeing washed in a car wash.
NOTE
Keep in mind that if the vehicle is equipped with the keyless locking and unlocking function *, the doors and tailgate/trunk lid
may open when washing the vehicle if the remote key is within range.
