Overheating the engine and transmission
In demanding driving conditions, such as when transporting heavy loads, driving in mountainousareas or in very hot weather there is a risk ofoverheating the engine or transmission.
• The engine's output may be slightly limited if there is a risk of overheating.
• Remove e.g., auxiliary lights mounted in frontof the grille in hot weather.
• If the temperature of the engine coolantbecomes too high, the warning symbol will illuminate and the message
Engine
temperature/Stop safely will be displayed.
Stop the vehicle as soon as possible in a safe place and let the engine idle for severalminutes.
• If the message
Engine temperature/High
temperature Turn off engine or Engine
coolant/Stop safely is displayed, stop
safely and turn off the engine.
• If the transmission begins to overheat, an alternative gear shifting program will beselected. An integrated protective functionwill also by activated, the warning symbol will illuminate and the message
Transmission
warmHigh temperature Reduce speed
or Transmission warmStop safely, wait
for cooling will be displayed in the instru-
ment panel. •
The air conditioning may be switched off temporarily.
• After a prolonged period of driving, do notturn off the engine immediately after stop-ping.
• The engine cooling fan commonly continuesto run for several minutes after the enginehas been turned off.
WARNING
The cooling fan (located at the front of the engine compartment, behind the radiator) maystart or continue to operate (for up to6 minutes) after the engine has beenswitched off.

Driving with a trailer
When towing a trailer, always observe the legal requirements of the state/province.
• All Volvo models are equipped with energy- absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par-ticular problems, but take into consideration:
• Increase tire pressure to recommended fullpressure.
• When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.
• If the automatic transmission begins to over-heat, a message will be displayed in the textwindow.
• Avoid overload and other abusive operation.
• Hauling a trailer affects handling, durability,and economy. •
It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safestop (check and observe state/local regula-tions).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch is notbeing used.

Back-up reader in the tunnel console
If Vehicle key not found is displayed in the
instrument panel, place the remote key in the back-up reader in the tunnel console (see theillustration) and try again to start the engine.
NOTE
When the remote key is in the back-up reader, be sure there are no other metallicobjects (e.g., other keys, coins, cell phones) inthe cup holder. This could affect the back-upreader's function.
If Vehicle start System check, wait is dis-
played in the instrument panel when you try to start the vehicle, wait until the message is nolonger displayed and try to start again.
CAUTION
If the engine does not start after the third try, wait for approximately 3 minutes before tryingto start it again to give the battery time torecover its starting capacity.
WARNING
• Always remove the remote key from the passenger compartment when leaving thevehicle and ensure that the ignition in mode
0.
• On vehicles with the optional Passive Entry, never remove the remote key fromthe vehicle while it is being driven ortowed.
• Always place the gear selector in Parkand apply the parking brake before leav-ing the vehicle. Never leave the vehicleunattended with the engine running.
• Always open garage doors fully beforestarting the engine inside a garage toensure adequate ventilation. The exhaustgases contain carbon monoxide, which isinvisible and odorless but very poisonous.
NOTE
After a cold start, idle speed may be noticea- bly higher than normal for a short period. Thisis done to help bring components in theemission control system to their normal oper-ating temperature as quickly as possible,which enables them to control emissions andhelp reduce the vehicle's impact on the envi-ronment.
CAUTION
•
When starting in cold weather, the auto- matic transmission may shift up at slightlyhigher engine speeds than normal untilthe automatic transmission fluid reachesnormal operating temperature.
• Do not race a cold engine immediatelyafter starting. Oil flow may not reachsome lubrication points fast enough toprevent engine damage.
• The engine should be idling when youmove the gear selector. Never accelerateuntil after you feel the transmissionengage. Accelerating immediately afterselecting a gear will cause harsh engage-ment and premature transmission wear.
• Selecting
P or N when idling at a stand-
still for prolonged periods of time will helpprevent overheating of the automatictransmission fluid.

Drive modes
Selecting a drive mode affects the vehicle's driv- ing characteristics to help make driving moreenjoyable or easier in certain types of situations.
The following systems are adapted to help pro- vide the best vehicle performance in the respec-tive drive modes: • Steering
• Engine/transmission/All Wheel Drive
*
• Brakes
• Pneumatic suspensionSuspension control
• Instrument panel
• Climate system settings
Select the drive mode best suited to the current driving conditions. Please be aware that not all modes can be selected in all driving situations. The selectedmode will be displayed in the instrument panel.
Selecting a drive mode
1. Press the DRIVE MODE control in the tun-
nel console.
> A pop-up menu will open in the center display.
2. Roll the control upward or downward to scroll to the desired drive mode.
3. Press the control again to select it. A drive mode can also be selected by tapping its button on the center display.
> The selected drive mode will be displayedin the instrument panel.
When a drive mode cannot be selected, one of the following messages may be displayed:
•
Not possible to select due to gear in manual
•Not possible to select due to low battery
•Not possible to select due to low temperature
•Not possible to select due to limitations
•Not possible to select due to high speed.
Available drive modes
WARNING
• Keep in mind that a hybrid vehicle using the electric motor does not emit enginenoise and may be difficult to detect fore.g., children, pedestrians, cyclists or ani-mals. This is particularly true at lowspeeds.
• Do not leave the vehicle in an unventila-ted area with a drive mode activated andthe gasoline engine switched off. Theengine will start automatically if thecharge level in the hybrid battery is lowand the resulting exhaust gases can bevery harmful to people or animals.

If the vehicle's speed goes above approx. 78 mph (125 km/h)
• If the driver wants more response than theelectric motor alone can provide
• If factors such as cold weather, etc., affectthe system or components
ECO climate
In the Pure drive mode, ECO climate in the pas-
senger compartment is activated automatically to help reduce energy consumption.
NOTE
When the Pure drive mode is activated, set-
tings for certain climate system/electricity- consuming functions are reduced. Some ofthese settings can be reset manually but fullfunctionality will only be restored by leaving the
Pure drive mode or by adapting the set-
tings in the Individual drive mode to full cli-
mate system functionality.
If condensation forms on the windows, tap the max. defroster button, which will function nor-mally.
OFF ROAD
This mode helps maximize the vehicle's capacity to traverse difficult terrain or poor roads. In OFF ROAD, ground clearance is maximized, the steering is light, All Wheel Drive and HillDescent Control are activated and a compass will be displayed between the speedometer and tach-ometer in the instrument panel. This drive mode can only be activated at low speeds (the permissible speed range will beshown on the speedometer). At higher speeds,OFF ROAD mode will be cancelled and AWD willbe activated.
CAUTION
OFF ROAD drive mode may not be used if the vehicle is towing a trailer without an elec-trical connection. This could result in damageto the pneumatic suspension system's bel-lows.
NOTE
•
This mode is not intended for normal street driving.
• Due to the increased ground clearance, ifthe OFF ROAD mode was selected whenthe engine was switched off, the suspen-sion will lower when the engine is restar-ted.
AWD
This mode offers improved traction on slippery surfaces by using four-wheel drive. It also helpsincrease directional stability at higher speeds, forexample when towing a trailer. In this mode, both the electric motor and the gas-oline engine are utilized, which results in higherfuel consumption. In the other drive modes, the vehicle automati- cally adapts the need for all-wheel drive accord-ing to the road surface and may activate the elec-tric motor or start the gasoline engine asrequired.
POWER
Power mode is intended for sportier, more active
driving. This mode maximizes the combined effects of the electric motor and the gasoline engine andprovides power to all four wheels. Response topressure on the accelerator pedal is more imme-diate and the transmission shifts up at higherrpm. Steering response is also more immediate,the suspension is stiffer and lower ground clear-ance reduces body roll when cornering. In this mode, both the electric motor and the gas- oline engine are utilized, which results in higherfuel consumption.

Use of the gasoline engineAn advanced control system determines the dis- tance that the vehicle can be driven using the gasoline engine, electric motor or both at thesame time. Its primary function is to use the motor/engine and the current available in the hybrid battery asefficiently as possible based on the characteris-tics of the various drive modes and the poweroutput requested by the driver by pressing theaccelerator pedal. In certain cases, temporary limitations in the sys- tem or mandatory functions to help maintain alow overall emissions level may result in greateruse of the gasoline engine.
